Antiinflammatory treatment

Accentuated by use of powerful bactericidal antibiotics, has led to the hypothesis that injury to the brain may be reduced by anti-inflammatory treatment. In experimental animals, the inflammatory process can be reduced using antiendotoxins (e.g. polymyxin B), blockers of endotoxin binding to macrophages (e.g. bactericidal permeability increasing factor or anti-CD14 antibodies), antibodies against cytokine mediators (e.g. interleukin 1 b or tumor necrosis factor-a), antibodies against neutrophil adhesion molecules, or agents which inhibit neutrophil and macrophage activation (e.g. steroids, pentoxifylline, or non-steroidal anti-inflammatory agents) (Feigin 1992). Many anti-inflammatory agents have proved beneficial in animal experiments, and convincing evidence for a beneficial effect from steroids in humans has now emerged. Initial studies conducted in the United States demonstrated clear benefit from the use of dexamethasone in reducing the severity of neurological sequelae,...

Nonsteroidal antiinflammatory drugs

Non-steroidal anti-inflammatory drugs such as ketorolac trometamol (ketorolac tromethamine) are used as components of 'balanced' analgesia because of their opioid-sparing effects in acute pain management. Potential adverse effects, such as gastric ulceration, renal impairment, and increased bleeding, limit their use in critical care. The synthesis of non-steroidal anti-inflammatory drugs selective for the isomer of cyclo-oxygenase responsible for inflammatory effects may improve the side-effect profile. Acetaminophen (paracetamol), traditionally available for oral or rectal administration, has been released in an injectable form. Dipyrone is a pyrazolone non-opioid analgesic that is much more potent than acetaminophen and probably has a 'central' analgesic action. It has minimal effects on the kidneys, gut, and platelet function. However, it has excellent antispasmodic activity and is valuable when both pain and visceral spasm are present. A rare occurrence of agranulocytosis has...

Anti Inflammatory Agents

Hwang et al. (33) and Sawusch et al. (34) used collagen shields to enhance the penetration of anti-inflammatory agents. Hwang et al. (33) compared the deliver of dexamethasone to the cornea and aqueous humor in normal rabbit eyes by four methods single 0.1 dexamethasone drop, hourly drops, collagen shields hydrated in 0.1 dexamethasone, and collagen shields hydrated in 0.1 dexamethasone followed by hourly topical 0.1 drops. Treatment with the drug-hydrated collagen shields plus hourly drops resulted in both peak and cumulative drug concentrations in the cornea and aqueous humor that were two- to fourfold greater than the concentration achieved by hourly drops alone. Collagen shields without accompanying drops yielded drug concentrations either equal to or greater than the peak and cumulative drug concentrations produced by hourly drops. The authors concluded that collagen shields significantly enhance dexamethasone penetration and would be useful for maximizing the delivery of this...

Possible Use of Antiinflammatory Agents in Treating Alzheimer Disease

The epidemiological and animal model data on traditional NSAIDs, but not selective COX-2 inhibitors, are in accord with what is known about neu-ropathological changes. COX-1 is concentrated in microglia, which are targets for antiinflammatory activity. In contrast, COX-2 is expressed constitutively in pyramidal neurons (Yasojima, Schwab, McGeer, & McGeer, 1999). Neurons are one of the few cell types in the body that constitutively express this COX isoform. Since impairment of COX-2 is unlikely to be beneficial to neurons, particularly the pyramidal neurons vulnerable to the AD process, selective inhibition of COX-2 is a questionable approach.

Antiinflammatory Effects Induced by Ethanol Ingestion

Protein levels, a plasma marker of inflammation, and decreases in the production of inflammatory cytokines such as interleukin-6. Using an intravital microscopic approach to examine postischemic leukocyte rolling, adhesion, and emigration in postcapillary venules in real time, we have demonstrated that antecedent ethanol exposure prevents adhesive interactions between circulating leukocytes and the endothelium from developing in tissues exposed to I R. The temporal expression of this protected or preconditioned state induced by ethanol ingestion is biphasic. The first or acute phase is short-lived, first becoming apparent within 1 hour after ingestion, with peak anti-inflammatory effects occurring 2 to 3 hours after intake, and then disappearing by 4 hours after consumption. The second or delayed phase of ischemic tolerance induced by ethanol becomes evident 18 to 24 hours after ethanol consumption and is notable for its magnitude of protection, being much more powerful than the acute...

Analgesic Antiinflammatory And Antispasmodic Activity

Carvacrol-rich (67 per cent) essential oil of Origanum onites, collected at the Izmir locality (Turkey), showed a marked analgesic activity as assessed by the tail-flick method in male albino mice. The analgesic activity of O. onites essential oil was dose-dependent. When applied at 0.33 ml kg, the activity of O. onites oil was comparable to that of morphine (applied at 1 mg kg), but at 0.03 ml kg more potent than the analgesic activity of fenoprofen (at 8 mg kg) (Aydin et al, 1996). The sample of O. onites, that originated from the Turkish Antalya region and was found to contain linalool (91 per cent) as a major component, showed no analgesic effects. On the basis of these data and on reports on prostaglandin inhibitory effects of carvacrol (Wagner etal, 1986), Aydin and co-workers consider carvacrol content as related to the analgesic activity of essential oil of O. onites. The effects of methanol extracts of O. majorana on human platelet anti-aggregant activity, which is related to...

Antiinflammatory Effects of Statins

Statins have been shown to possess multiple antiinflammatory actions that play an important role in mediating their vasculoprotective properties. Conditions associated with impairment of NO availability and increased oxidant stress, such as hypoxia and ischemia-reperfusion, induce an inflammatory endothelial phenotype characterized by enhanced expression of the surface adhesion molecules, P-selectin, ICAM-1, and VCAM-1. By enhancing eNOS function and reducing ROS, statins decrease expression of adhesion molecules and inhibit leukocyte-EC binding and transmigration in vitro at concentrations as low as 0.01 M. In animal models, statins decrease leukocyte adhesion within the microvasculature in response to thrombin, bacterial toxins, and low-dose LNMA. High-dose LNMA reverses these effects, and they are not observed in eNOS knockout mice. Statins may directly inhibit the transcription factors NF-kB and activator protein-1 (AP-1), and induce the nuclear receptors PPARa and g which...

Discovery of R805 nimesulide

Sulphasalazine 1962

The development of nimesulide arose from investigations by Dr George (GGI) Moore (a medicinal-organic chemist Fig. 2), Dr Karl F Swingle (a pharmacologist), Dr Bob (RA) Scherrer (a medicinal chemist) and their colleagues at Riker Laboratories Inc (Northridge, California, US, later part of the 3M Company at St Paul, Minnesota, US). They had the idea that since the evidence in the late 1960s suggested that free radicals were important in chronic inflammatory diseases then drugs which scavenge these radicals might have novel anti-inflammatory mechanisms to control chronic inflammation. They undertook a detailed structure-activity analysis and determined the pharmacological properties of the sulphonamides 12 . This class of agents had previously been considered in the 1940s to have antirheumatic activity as a consequence of their antibiotic effect by Svartz and her colleagues at Pharmacia in Sweden and this culminated in the development of the sulphonamide-salicylate conjugate,...

Abstract Of The Disclosure

Diphenyl ethers wherein an alkyl- or haloalkylsulfou-amido substituent group is oriented ortho to the ether linkage and a nitro or amino substituent is oriented in the 4 or 5 positions with respect to the sulfonamido group are active anti-inflammatory agents. This invention relates to diphenyl ethers substituted by an alkyl- or haloalkylsulfonamido group and a nitro or amino group (as defined herein) wherein the orientation of the groups is critical. In particular the invention relates to such compounds wherein the alkyl- or haloalkylsulfonamido group is oriented in the 2 position (ortho) with respect to the ether linkage and the nitro or amino group is oriented in the 4 or 5 position with respect to the alkyl- or haloalkylsulfonamido group, and to salts thereof, gg The rings and the sulfonamido nitrogen are optionally substituted. The compounds are anti-inflammatory agents. Methods for the preparation and use of the compounds are also described. Many non-steroidal anti-inflammatory...

In vivo pharmacological actions

Swingle, Moore and co-workers in their preclinical pharmacological investigations of nimesulide (then coded R-805) at Riker Laboratories showed that the drug had relatively potent acute and chronic anti-inflammatory, analgesic and antipyretic effects, in conventional animal models 1, 9 . A summary of the acute anti-oedemic potencies of nimesulide in rats compared with that of some standard reference non-steroidal anti-inflammatories (NSAIDs) shows it has anti-inflammatory effects in the rat paw carrageenan assay some 2-3 times more so than that of indomethacin and naproxen and is also more potent than other NSAIDs (Tab. 1 9 ). Adrenalectomy had no effect on the acute anti-inflammatory effects of nime-sulide in rats although the anti-inflammatory effects of phenylbutazone (15 mg kg, p.o.) were reduced in adrenalectomised rats. This indicates that with the latter drug the anti-inflammatory effects are mediated, in part, by adreno-cortical stimulation, a phenomena not apparent with...

Structural aspects of cyclooxygenase COX activity and COX2 inhibition by nimesulide

Since inhibition of COX-2 alone has been considered sufficient to obtain an anti-inflammatory effect and most mechanism-based side effects result from blockade of COX-1 activity in normal tissues, targeting COX-2 stimulated development of new agents (coxibs) with an improved safety profile 78 . Several classes already

Novel nonpain uses of nimesulide

Early epidemiological studies, especially in arthritic patients taking NSAIDs long-term, suggested that there may be improvements in cognitive function or preventative effects of these drugs on the symptoms of AD 195-199 . More convincing data came from the longitudinal study in 1,686 patients by Stewart et al. 200 who showed that the risk of developing AD was reduced by 60 following use of NSAIDs for two or more years that by aspirin users over the same period was associated with risk reduction of 36 , while there was no significant benefits from use of paracetamol over the same period. Another epidemiological study involving 1,648 patients showed that concurrent use of anti-inflammatory agents (and oestrogens in women) was associated in improvements in mental functions and cognition 201, 202 . A smaller scale clinical trial in 41 patients with mild-to-moderate AD treated for 25 weeks with a combination of diclofenac and miso-prostol (as a gastroprotective agent) did not show any...

Nimesulide and neutrophil functional responses

Last 3-4 decades, a variety of non-prostaglandin mediated effects of non-steroidal anti-inflammatory drugs have been reported 128-133 , suggesting that inhibition of cyclooxygenase does not represent the only explanation for the activity of these drugs. In this regard, neutrophils are considered a major potential target for NSAIDs because of the relevant role of these cells in natural and immune-driven inflammatory responses 128-130, 133-135 . Here we consider the role of neutrophils in inflammatory reactions and review in vitro and in vivo effects of nime-sulide on activities of this cell population.

Cox2human Sglddinptvllkerstel Cox2mouse Srlddinptvlikrrstel

Exist of compounds that display such selectivity, and many of them have in common the presence of two appropriately substituted aromatic rings on adjacent positions about a central, usually heterocyclic ring 79 . Remarkably, nimesulide shares some of these characteristics (Fig. 6) 46 , but was already on the market as an anti-inflammatory agent without the gastrointestinal (GI) side effects of classical NSAIDs prior to the discovery of the second COX isoform 40 . Indeed, a selectivity of this drug towards the PGHS involved in inflammation was suggested more than 25 years ago when a lack of correlation was found between its potency to inhibit PGHS in preparations from bovine seminal vesicles and its anti-inflammatory potency in vivo, which was comparable to that of indomethacin 46 . More recently, nimesulide has been demonstrated to be a potent time-dependent inhibitor of COX-2 39, 40, 77 , like that of other COX-2 inhibitors, and has been shown to competitively inhibit binding of 3H...

Miscellaneous uses

A patent claiming benefits of nimesulide as an 'anti-cataract agent' has been reported 242 . The evidence was based on inhibition by nimesulide of depolymerisation of hyaluronic acid and the development of opacity of rat lens incubated in vitro for 4 days in the presence of glucose and foetal calf serum, the treatment of which leads to lens protein denaturation 242 . No in vivo evidence appears to have been reported to support these claims, although other NSAIDs have been found to suppress formations of cataract and reduce inflammation during and

Dorsal Horn Neuron

Studies in laboratory animal models have provided evidence for both central as well as peripheral actions of NSAIDs in mediating pain responses 246, 247 . Thus C-fibre activity in the thalamus is blocked by NSAIDs 246 . Most of the data that further our understanding of the mode of action of NSAIDs is derived from animal models of hyperalgesia, which demonstrate that high anti-inflammatory doses of other NSAIDs do not affect physiological nociception in animals 247 . However, nimesulide has recently proved able to modulate nociceptive (physiological) pain 248 . Bianchi et al. 249 recently demonstrated that nime-sulide completely prevents the development of thermal hyperalgesia induced by injection of formalin in the tail, producing an inhibitory effect that was more marked and complete than that of diclofenac and or celecoxib. In addition, nime-sulide was also capable of reducing the mechanical hind paw hyperalgesia induced by the intraplantar injection of Freund's complete adjuvant...

The Immune Response to Fungi From Microbe Sensing to Host Defensing

Most pathogenic fungi need a stable host-parasite interaction characterized by an immune response strong enough to allow host survival without elimination of the pathogen, thereby establishing commensalisms and latency. Therefore, the balance of pro-inflammatory and anti-inflammatory signaling is a prerequisite for successful host-fungus interaction. In light of these considerations, the responsibilities for virulence is shared by the host and the fungus at the pathogen-host interface, regardless the mode of its generation and maintenance. Studies with C. albicans have provided a paradigm that incorporates contributions from both the fungus and the host to explain the theme of the origin and maintenance of virulence for pathogens and commensals (Romani, 2004a). Through a high degree of

Nervous System Communication to the Immune System

There are also data that support a role for the parasympathetic nervous system in influencing the immune system. Both muscarinic and nicotinic acetylcholine (Ach) receptors have been detected on T lymphocytes and macrophages (Tracey 2002). The cholinergic anti-inflammatory pathway, via the vagus nerve, may control the inflammatory response by inhibiting cytokine release from macrophages bearing nicotinic Ach receptors (Pavlov, Wang, Czura, Friedman, and Tracey 2003). Thus, since lymphoid tissues are innervated with sympathetic and parasympathetic fibers and contain specific receptors on their cell surfaces, it seems reasonable to perceive a mechanism by which the nervous system may communicate or regulate specific aspects of the immune response.

Contrastinduced Nephrotoxicity

A number of risk factors for the development of CIN have been described, particularly pre-existing renal insufficiency (21-26). Patients whose renal failure is the result of diabetic nephropathy are at even greater risk, and when renal failure occurs, it is more likely to be irreversible (27). However, the presence of diabetes mellitus alone (in the absence of renal failure) is probably not a risk factor for contrast-induced renal failure (28-30). Other risk factors that have been implicated include American Heart Association class IV congestive heart failure, hyperuricemia, dehydration, concurrent use of such nephrotoxic drugs as aminoglycoside antibiotics and nonsteroidal anti-inflammatory agents, advanced age, and administration of large doses of

Pharmacological support

Attempts to modify the inflammatory process in ARDS with pharmacological agents have met with only limited success. Agents used have included non-steroidal anti-inflammatory drugs (e.g. ibuprofen), prostaglandins (alprostadil), thromboxane synthetase inhibitors (ketoconazole), antioxidants ( -acetylcysteine), and neutrophil activator inhibitors (e.g. pentoxifylline). Corticosteroids are beneficial in animal models, but clinical trials have been disappointing. High-dose steroids have a place in the treatment of patients with significant fibroproliferation or high bronchoalveolar eosinophil counts, where sepsis is excluded. Most progress has been made in the area of inhaled vasodilators used in an attempt to improve ventilation-perfusion relationships and decrease intrapulmonary shunting. This is achieved by increasing blood flow to ventilated lung units. Reducing pulmonary vascular resistance may also decrease pulmonary edema formation and therefore increase arterial oxygenation....

Mechanism of Action

The anti-inflammatory and immunosuppressive actions of steroids are complex, and, to date, not fully understood. The effects of steroids are mediated through the binding of these steroids to cytoplasmatic glucocorticoid receptors in target cells. Glucocorticoid receptors are expressed on almost every type of human cell, including lymphocytes, monocytes, and neutrophils (22). Steroids have several effects on the pathogenesis of inflammation. In general, steroids suppress cellular immunity more than humoral immunity. Steroids inhibit the production of multiple The anti-inflammatory properties of steroids may explain the efficacy of selective injections in pain relief among patients with radicular pain. Some authors have proposed that radicular pain is a result of chemical radiculitis induced by leakage of breakdown products such as phospholipase A2 from a degenerating nucleus pulposus (14). Other causes of nerve root i rritation include mechanical compression by disk herniation or...

The Central Role of the Tryptophan Metabolic Pathway in Tolerance and Immunity to Fungi

The inflammatory anti-inflammatory state of DC is strictly controlled by the metabolic pathway involved in tryptophan catabolism and mediated by the enzyme IDO. IDO has a complex role in immunoregulation in infection, pregnancy, autoimmunity, transplantation, and neoplasia (Mellor & Munn, 2004). IDO-expressing DC are regarded as regulatory DC specialized to cause antigen-specific deletional tolerance or otherwise negatively regulating responding T cells. In experimental fungal infections IDO blockade greatly exacerbated infections, the associated inflammatory pathology and swept away resistance to reinfection, as a result of deregulated innate and adaptive immune responses caused by the impaired activation and functioning of suppressor CD4+ CD25+ Treg cells producing IL-10 (Bozza et al., 2005 Montagnoli et al., 2006). The results provide novel mechanistic insights into complex events that, occurring at the fungus-pathogen interface, relate to the dynamics of host adaptation by fungi....

Postoperative Analgesia

Non-steroidal anti-inflammatory drugs (NSAIDs) can be a useful adjunct for post-operative pain control. However, NSAIDs have some well-known adverse effects, including effects on platelet function and renal function, and may increase CBF 24 . Further studies comparing the efficacy and safety of different analgesic regimens in craniotomy patients are needed.

Bidirectional Communication and Sleep

Decreased rapid eye movement (REM) sleep (Bryant, Trinder, and Curtis 2004). Infection with influenza virus in human causes reduced sleep during the incubation period but increased sleep during the symptomatic period (Smith 1992). Exposure to microbial components such as lipopolysaccaride and muramyl peptides mimics the sleep effect (Mullington et al. 2000). Finally, increases in the intracerebral or plasma levels of TNF or IL1-P result in an increase in SWS duration, whereas antagonizing these cytokines with specific antibodies inhibit SWS (Opp and Krueger 1994). It appears that most proinflammatory cytokines are somnogenic, whereas most anti-inflammatory cytokines are not.

Dampening Inflammation and Allergy to Fungi A Job for Treg Cells

A number of clinical observations suggest an inverse relationship between IFN-y and IL-10 production in patients with fungal infections. High levels of IL-10, negatively affecting IFN-y production, are detected in chronic candidal diseases, in the severe form of endemic mycoses and in neutropenic patients with aspergillosis (Romani, 2004b). Fungal polysaccharides are known to negatively modulate CMI through the production of IL-10, a finding suggesting that IL-10 production may be a consequence of infection (Romani & Puccetti, 2006b). However, tolerance to fungi can also be achieved through the induction of Treg cells capable of finely tuning antifungal Th reactivity. Naturally occurring Treg cells operating in the respiratory or the gastrointestinal mucosa accounted for the lack of pathology associated with fungal clearance in mice with fungal pneumonia or mucosal candidiasis (Montagnoli et al., 2002, 2006). Distinct Treg populations capable of mediating anti-inflammatory or...

Disease Modification Studies

With AD in mild-to-moderate stages using nonsteroidal anti-inflammatory drugs (NSAID) have failed, despite the weight of evidence from epidemiological research and the biological plausibility of an inflammatory component to AD pathology (McGeer, Schulzer, & McGeer, 1996). It may be that treatment with NSAID in the presymptomatic or in the prodromal stages of AD would be a more appropriate time from a pathophysiology point of view, or that doses tested so far were too low. On the other hand, studies in these stages of AD require 3-5 years, a very long time for a proof of concept. Alternatively, patients groups at very high risk of progression could be considered, such as presenilin mutation carriers, or aMCI carrying the apoE4 genotype with hippocampal atrophy (Pennanen et al., 2006).

Preventing AD and future treatments

A number of factors such as non-steroidal anti-inflammatory drugs, hormone replacement therapy, and the antioxidant vitamin E, might be of some use in strategies to prevent AD. Prevention could be primary before any signs of the disease or secondary after some manifestation of the process. Primary preventive measures would have to be directed at either the entire population or to groups at risk (identified by family history or genotype, for example), and therefore would have to be entirely benign and almost cost-free to be acceptable. Secondary prevention, possibly in those with memory impairments not amounting to dementia (minimal cognitive impairment), is a more realistic prospect rendering the determination of the very earliest signs of disease or evidence of a prodromal state a high priority. A biological marker for AD would have immense utility in both clinical practice and in clinical trials. Markers suggested have included platelet membrane fluidity and measurement of amyloid,...

Neuroinflammatory processes

It has been suggested that immune alterations may occur prior to amyloid deposition and neuronal degenerations. In PS-1 mutant knock-in mice, calcium regulation is altered in neurons which makes them more vulnerable to A excitotoxicity and apoptosis. These and other changes in lymphocyte signaling occur prior to any evidence of degenerative changes in the brain (250). Moreover, several cytokines may serve neuroprotective functions, e.g. TNF-a mediates anti-apoptotic and antiexcitatory pathways, e.g. Mg-SOD and Bcl-2 inducing increased resistance to cell death (127). The spectrum of antiinflammatory mediators upregulated in AD, suggests many routes for further therapeutic intervention (245).

Insect Models for Studying Microbial Pathogens of Mammals

In vertebrates the different aspects of the innate and adaptive immune responses intertwine, connect and overlap. For example, interleukin-12 (IL-12), an anti-inflammatory cytokine that acts as an immunological messenger, is produced and secreted by macrophages during an immune response. IL-12 activates T cells, which in turn activate other cells involved in the immune response. In order to investigate those responses that are solely components of the innate immune response, employing an invertebrate model such as an insect that relies exclusively on an innate immune response, is advantageous. It is also becoming increasingly

Etiology And Risk Factors

Reports from epidemiological studies of protective effects of certain prescribed medication, non-steroidal anti-inflammatory drugs, hormone replacement therapy (HRT) and cholesterol-lowering therapies are now being investigated in randomized controlled trials. The randomized controlled trial of HRT in postmenopausal women indicated, against expectation, that it increased rather than lowered the incidence of dementia.

Gastroduodenal sources

While melena and hematemesis alone may be caused by any lesion in the upper gastrointestinal tract, the appearance of coffee-ground vomitus or gastric aspirate indicates that blood has been in contact with acidic gastric contents. Erosive gastroduodenitis is suspected when a patient with upper gastrointestinal bleeding gives a history of having recently ingested non-steroidal anti-inflammatory drugs or significant amounts of alcohol. These patients may also give a history of upper abdominal discomfort, occurring irregularly for days or weeks prior to the bleeding episode, and may have noted that liquid antacids provided them with temporary relief. The alcoholic patient with erosive gastritis may be either a chronic or a binge drinker bleeding from such lesions may occur at any age. Stress ulceration is a process similar to erosive gastritis, but occurs primarily in patients confined to intensive care units, suffering from severe injuries, infections, or cardiovascular problems, and...

Inhibition of Mediator Induced Macromolecular Leakage

Theless they all inhibit macromolecular leakage in postcapil-lary venules, thus emphasizing that in spite of increased blood flow and perfusion pressure in the arterioles that should favor plasma leakage from the venules, the effect of the drug localized to receptors on the endothelial cells of the postcapillary venules is the dominant factor in the regulation of plasma leakage in inflammation. Neutrophil-induced changes in vascular permeability are the result of a complex interaction between adhesive proteins expressed on the surface of leukocytes and endothelial cells, selectins, and integrins, which finally results in the firm adhesion of leukocytes in postcapillary venules. It is possible to interfere with the leukocyte-endothelial cell interaction at different steps. Monoclonal antibodies against adhesion glycopro-teins have been used to elaborate mechanisms of leukocyte rolling and adhesion. Dextran sulfate, and possibly also heparin, acts by neutralizing charged peptides...

Concluding Remarks

Transduction pathways as a redox regulator but also inhibits the neutrophil extravasation as an anti-inflammatory drug. Evidence shows that TRX-Tg mice are resistant in several tissue injury models, and that the administration of rhTRX can ameliorate the tissue damage. Thus, since TRX is considered as a unique and promising target molecule regulating the inflammation, the translational research using rhTRX as a therapeutic drug of ALI ARDS is in progress. In the near future, the clinical application of TRX may be expanded to other oxidative stress-associated diseases.

Autacoid Production by Hemodynamic Forces

In all higher organisms the cardiovascular system represents an elaborated transport network, which is essential for the maintenance of vital functions by supplying oxygen and nutrients to tissue and removing by-products of metabolism. In order to adapt to the varying demands of the tissues, the circulatory system has evolved central and local control mechanisms that act in concert to maintain an adequate blood flow. At a given blood pressure, the blood flow to each organ is determined by the peripheral vascular resistance of this organ, which is adjusted by a variety of local mechanisms affecting the tone of the smooth muscle cells in the so-called resistance vessels, that is, small terminal arteries and large and small arterioles. Endothelial cells, situated at the interface between blood and the vessel wall, play a crucial role in controlling vascular tone and homeostasis, particularly in determining the expression of pro- and antiinflammatory genes. Many of these effects are...

Hypothalamic PituitaryAdrenal Axis and Glucocorticoid Responses

The many functions of glucocorticoids are elicited through the glucocor-ticoid receptor (GR), a cytosolic receptor. This receptor, along with receptors such as the thyroid hormone, mineralocorticoid, estrogen and progesterone receptors, is a member of the nuclear hormone receptor superfamily (Evans, 1988). For GR, the receptor is located in the cytoplasm in a protein complex, which includes Hsp90 and Hsp70, in the absence of ligand. When the ligand binds, GR is released from the protein complex, dimerizes, and translocates to the nucleus. Once in the nucleus, GR regulates gene expression by binding to specific DNA sequences called glucocorticoid response elements (GREs) (Aranda and Pascual, 2001 Schoneveld et al., 2004). GR is able to upregulate gene expression, such as for the gluconeogenic enzyme tyrosine animotransferase (TAT) (Jantzen et al., 1987), through direct DNA binding. However, it can also repress gene activation, such as the POMC gene, by direct binding to DNA sequences...

Local Complications After Radiation Synovectomy

(cooling with ice packs, over-the-counter anti-inflammatory drugs) Joint puncture is associated with the risks of local bleeding, bruising, and infection Risks associated with application of radionuclides are local tissue necrosis as well as radionuclide (47). Aggravation of local pain and swelling 6 to 48 hours after treatment has been observed in about 15 of our patients, mostly in finger and toe joints which received no steroid application. These symptoms are usually self-limited without further intervention and can be treated simply by cooling the joint with ice packs or, if necessary, with anti-inflammatory drugs such as ibuprofen.

General Considerations

Recently, significant emphasis has been placed on elucidating the cellular and molecular mechanisms governing the pulmonary microvascular endothelial cell response to inflammatory stimuli 16 . Constituent protein flux is greatly attenuated in response to inflammation 17,18 . This enhancement in barrier property is associated with increased expression of focal adhesion complexes that promote cell-cell contact 19-21 . Increases in cAMP may account for enhanced barrier properties of pulmonary endothelial cells, since elevating cAMP may reduce inflammation permeability by promoting cell-cell contact. When an aerosolized drug is administered to the respiratory tract, it must cross the epithelial cell barrier to enter either the lung tissue (topical effect) or

Yarrow Achillea Millefolium

Yarrow stops bleeding wounds and is used as a healing lotion and ointment. It also is used to reduce pain and heavy bleeding due to menstrual irregularities and helps to regulate the menstrual cycle. Yarrow enhances circulation, lowers blood pressure, and has an antispasmodic and anti-microbial effect. It also has an anti-inflammatory effect on skin and on mucous membranes. The most frequently reported side effect of Yarrow is dermatitis (skin rash). Yarrow should not be used for patients who have epilepsy or are pregnant.

Other causes of acute intrinsic renal failure

Other less common etiologies of ARF include acute allergic interstitial nephritis, characterized by inflammatory cell infiltration and interstitial edema. It is typically induced by antibiotics (penicillins, cephalosporins, and sulfonamides), diuretics (hydrochlorothiazide), non-steroidal anti-inflammatory drugs, allopurinol, and angiotensin-converting enzyme inhibitors (captopril). Renal artery or vein occlusion and glomerulonephritis may also reduce glomerular filtration rate and generate ARF, the etiology of which is often suspected by the clinical setting.

Relevant Clinical Data on Disease Modification

Chronic treatment with the Ml agonists, AF102B and talsaclidine, decreased significantly CSF Ap in AD patients (Hock et al., 2003 Nitsch, Deng, Tennis, Schoenfield, & Growdon, 2000). Physostigmine and the anti-inflammatory drug, hydroxychloroquine, were not effective on CSF Ap levels when tested in AD patients in the same study as AF102B (Nitsch et al.). Also, galantamine, rivastigmine, and donepezil were ineffective on CSF Ap levels in AD patients (Parnetti et al., 2002).

Metabolic abnormalities

Kaliuresis is impaired in chronic renal failure with normal plasma levels maintained by an adaptive increase in secretion by the remaining nephrons and by increased colonic excretion under the influence of aldosterone. Potassium-sparing diuretics, angiotensin-converting enzyme inhibitors, and non-steroidal anti-inflammatory drugs can precipitate hyperkalemia, and the composition of fluid replacement and feeding should be considered with care.

Upper gastrointestinal tract

Increased gastrin levels in response to hypochlorhydria, reduced renal clearance, stress, and hyperparathyroidism. Biliary reflux due to gastrin-induced pyloric sphincter incompetence coupled with reduced basal bicarbonate excretion by the pancreas may be contributory, but there appears to be no predisposition to infection with Helicobacter. Clinically significant disease is often silent, and bleeding is very commonly precipitated by pro-ulcerogenic drugs such as aspirin, non-steroidal anti-inflammatory drugs, and steroids. Critically ill patients should receive enteral feeding and H 2 antagonists, as prophylaxis with treatment of established gastritis or ulcers is the same as for non-uremic patients, although drug dosages may require adjustment.

Damage to the Basement Membrane

Tumor cells adhere more efficiently to the exposed collagen of a damaged blood vessel than to normal vessel walls, and so damaged areas provide prime targets for cell arrest. Vessels can be damaged by trauma or inflammation in fact, evidence is mounting that surgical removal of some tumors can promote tumor metastasis to existing wounds.13,14 This effect may also be facilitated by the growth factors present in wound fluid. Therefore, natural compounds that protect the vascula-ture or reduce inflammation may limit cell arrest. A host of anti-inflammatory and anticollagenase compounds have already been discussed (see Chapters 8 and 9). Some natural compounds like proanthocyanidins appear to have a specific affinity for vascular tissue and may be particularly useful.

Mechanisms of Immune Signaling to the Brain

Endothelium consists of the luminal lining of cells within blood vessels, rendering them in contact with virtually every circulating substance, including those derived from immune activation such as cytokines. Endothelial cells express a diverse array of substances and receptors, including receptors for IL-1, IL-6, and interferons, which have been implicated in modulation of sleep (Opp 2005) and they also express enzymes necessary for producing prostaglandins. Prostaglandin E2 (PGE2) is strongly implicated in the mediation of several illness responses, including fever and activation of the HPA axis, based on the observations that anti-inflammatory drugs that prevent the synthesis of prostaglandins prevent these responses to systemic cytokine treatment. Compelling evidence indicates that PGE2 produced in endothelial cells contributes to actions of circulating IL-1 (Ericsson, Arias, and Sawchenko 1997). For instance, IL-1 receptors are codistributed in endothelial cells with synthetic...

Nongenetic causes of Parkinsons disease A R Chade M Kasten and C M Tanner

Study of the nongenetic causes of Parkinson's disease (PD) was encouraged by discovery of a cluster of parkinsonism produced by neurotoxic pyridine (MPTP) in the 1980s. Since that time, epidemiologic investigations have suggested risk factors, though their results do not establish causality. Pesticide exposure has been associated with increased risk in many studies. Other proposed risks include rural residence and certain occupations. Cigarette smoking, use of coffee caffeine, and non-steroidal anti-inflammatory drugs (NSAIDs) all appear to lower risk of PD, while dietary lipid and milk consumption, high caloric intake, and head trauma may increase risk. The cause of PD is likely multifactorial. Underlying genetic susceptibility and combinations of risk and protective factors likely all contribute. The combined research effort by epidemiologists, geneticists, and basic scientists will be needed to clarify the cause(s) of PD.

Aging and Conformational Diseases Failures of Law Enforcement Leading to Lawlessness

Interestingly, Hsp70 has been shown to protect against cell death by directly interfering with the mitochondrial apoptosis pathway.31 This is exemplified in the case of the acute respiratory distress syndrome (ARDS), which is an inflammatory response in the lungs culminating in necrosis and fatal apoptosis. Sepsis-induced ARDS in rats correlates with the specific failure of Hsp70 expression in alveolar tissues.32 In contrast, in a rat model of sepsis-induced ARDS, adenovirus-mediated transient expression of Hsp70 in the lungs effectively prevented apoptosis, lung failure and dramatically improved survival.33 The overproduction of molecular chaperones observed following treatments with various nonsteroidal anti-inflammatory drugs (NSAIDs), such as sodium salicylate,13 ibuprofen,34 and less classical Hsp-inducers such as celastrol,35 resveratrol (the French paradox), geranylgeranylacetone,37 may be responsible for the observed reduction of damages related to reactive oxygen species and...

Some Major Biomarkers Related To Multistage Carcinogenesis

A promising strategy applicable to the identification and development of chemopreventive agents is the inhibition of inflammation. Cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) are important enzymes that mediate inflammatory processes. Improper upregulation of COX-2 and or iNOS is associated with the pathophysiology of certain types of human cancers as well as with inflammatory disorders. Tumor promoters and lipopolysaccharide can induce inflammation through the overexpression of COX-2 and iNOS with the concomitant generation of ROS and RNS. Because inflammation is closely linked to tumor promotion, substances with potent anti-inflammatory activities are anticipated to exert chemopreventive effects on carcinogenesis, particularly in the promotion stage.

Catalytic Selectivity of CYP2C9

Substrates for CYP2C9 include many non-steroidal anti-inflammatory drugs plus a reasonably diverse set of compounds including phenytoin, (S)-warfarin and tolbutamide. All the substrates with routes of metabolism attributable to CYP2C9 have hydrogen bond donating groups a discrete distance from a lipophilic region which is the site of hydroxylation. The hydrogen bond donating groups and sites of metabolism on each of the substrates have been overlaid with those of phenytoin to produce a putative template of the active site of CYP2C9 (Figure 7.7). The mechanism of action of CYPs is radical rather than electrophilic and the actual substitution pattern is important the role of chlorine is one of blocking rather than deactivation. Many non-steroidal anti-inflammatory drugs are substrates for the

Radioiodine Complications

Neck edema, nausea, and gastritis (95). The salivary glands concentrate iodine and sialoadenitis may occur in about 30 of patients treated with radioiodine (96). It is characterized by pain, tenderness, and swelling of the salivary glands. Some patients suffer from reduced salivary gland function for more than one year after therapy with I-131. The use of lemon juice or lemon candies and abundant water ingestion reduces the incidence and severity of sia-loadenitis and reduces absorbed radiation dose to the salivary glands. Recently, a study indicated that an early start of sucking lemon candy may provoke an increase in salivary gland damage suggesting that lemon candy should not be given until 24 hours after therapy with I-131 (97). The use of amifostine may reduce significantly the damage to salivary glands, mainly when high doses are administered (98). Radiation thyroiditis and neck edema (99), when symptomatic, are usually treated with nonsteroidal anti-inflammatory drugs, or with...

Combating Inflammation

Although inflammation is a natural response to injury, this process can be uncomfortable for a patient, especially when there is fever, pain, and swelling. Anti-inflammatory medication can be given to reduce the inflammatory process and bring comfort to the patient. Anti-inflammatory medication stops the production of prostaglandins resulting in a decrease in the inflammatory process. There are three categories of anti-inflammatory medication. Many anti-inflammatory medications fall within all three categories. Aspirin is one of them, which is the oldest and least expensive anti-inflammatory medication available and, along with acetaminophen and ibuprofen, is the choice for relieving headaches. Corticosteroids, such as prednisone, are frequently used as anti-inflammatory agents. This group of drugs can control inflammation by suppressing or preventing many of the components of the inflammatory process at the injured site. There are other anti-inflammatory medications that are not...

Types And Causes Of Hypertension

The sympathetic nervous system or insulin resistance can also cause hypertension.19 Abnormal renin that triggers angiotensin21 and oxidation that produces aldosterone21 are further risk factors.19 Other causes of clinical variable hypertension are physiologic variables.22 The first is vascular tone, which establishes the elastic properties of veins and arteries, vessel diameter, and vascular resistance.22 Additional variables causing high blood pressure are inotropic state and heart rate.22 Hypertension can result also from the use of drugs, medications, and other substances such as oral contraceptives, nonsteroidal anti-inflammatory drugs, licorice, cocaine, and amphetamines.23

Degeneration of Chronically Demyelinated Axons

Recent studies indicate that although significant axonal loss often occurs early during RR-MS in association with inflammation, permanent disability is not clinically evident because of the compensatory capacity of the CNS. In addition most symptoms are transitory because they are caused predominantly by inflammation, edema, and demyelination. Once axonal loss surpasses the reserve compensatory capacity of the CNS, however, irreversible neurological disability becomes clinically evident and the disease transitions to the SP-MS phase (Fig. 1). During the SP-MS stage of the disease, active inflammation is no longer prominent, as indicated by MRI and suggested by the lost efficacy of anti-inflammatory therapeutics. Although inflammation is no longer prominent during SP-MS, there is a steady progression of irreversible neurological disability. Also, CNS atrophy and axonal loss continue as indicated by MRI measurements (Rudick et al., 1999a Miller et al., 2002) and MRS measurements (De...

Prognosis and predictive factors

Laryngeal IMT is usually cured by conservative resection 2761 . Corticosteroid and nonsteroidal anti-inflammatory agents have been used for treatment resulting in regression in some patients 795,2487 . A recurrence rate of approximately 25 has been reported for extrapulmonary IMTs 467 . IMT was originally believed to be a reactive non-neoplastic lesion. This has been refuted by the above genetic studies. An occasional

Microglial Response in Cortical MS Lesions

Alzheimer's disease (AD), activated microglia are associated with damaged neurites and neuronal loss (Haga et al., 1989 McGeer et al., 1992 Mochizuki et al., 1996). Some of the most promising AD therapeutics are anti-inflammatory therapies targeting activated microglia (Breitner, 1996 Combs et al., 2000). Thus, similar anti-inflammatory therapies, which reduce microglial activation in the cerebral cortex, may benefit patients with MS.

Use of medication to delay symptom progression

Nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen have been associated with a lower incidence of dementia. Because of the risks of gastrointestinal and renal toxicity, these agents cannot be routinely recommended as a preventive measure against Alzheimer's disease.

Novel therapies in sepsis

Greater understanding of the pathophysiology of sepsis has stimulated the development and investigation of agents that modulate different components of the inflammatory response. These drugs have been targeted at triggers (e.g. endotoxin), cytokines (e.g. tumour necrosis factor, interleukin (IL)-1), and effector cells and their products (e.g. neutrophils, free oxygen radicals, nitric oxide) or aim to boost a general anti-inflammatory response (e.g. steroids). An increasing area of research is in replacement or augmentation of endogenous anti-inflammatory systems, e.g. activated Protein C, antithrombin-III, IL-10, as there is an increasing realisation of the degree of disruption and imbalance between pro- and anti-inflammatory substances.

Future Directions in the Treatment of Alzheimers Disease

Several new directions in therapeutic approaches are being investigated. One is to lower Ap peptide levels and thus reduce Ap deposits through the use of molecules that prevent the proteolytic cleavage of amyloid precursor protein or through a novel immunization technique that would use antibodies to remove the Ap peptides from the cells and brain. Other approaches being examined are targeted at blocking the more downstream effects, such as the use of antiinflammatory agents and antioxidants.

Further Developments And Key Issues

Further improvements to the sensitivity and specificity of the method include stratifying by age and sex examining serious or fatal reactions only. (The proportion of reactions that are fatal, stratified by age is itself a potential signalling method.) Where a drug has a well-known ADR that is reported very frequently, such as gastrointestinal (GI) bleeding with non-steroidal antiinflammatory drugs (NSAIDs), this will distort the PRR for other reactions with that drug. The best approach is then to remove the known reactions from the totals for that drug and the database as a whole and recalculate the PRR for all other reactions with that drug. This is simple to do on an ad hoc basis but is more difficult to implement in an automated way.

Outcome Measures Used to Measure MS Disease Severity

By the end of the 1990s, groups from around the world were working on methods to quantify CNS atrophy in MS, and reports were appearing at an increasing rate in the literature. As a result, an international workshop was convened in London, England, in November 2001. At that workshop, it was noted that atrophy was an attractive disease measure because it reflected a global marker of the adverse outcome of MS pathology. The workshop attendees reached the consensus that atrophy in MS probably reflects both inflammation-induced axonal loss followed by wallerian degeneration and postinflammatory neurodegeneration that may be partly due to failure of remyelination. It was concluded that atrophy provides a sensitive measure of the neurodegenerative component of multiple sclerosis and should be measured in trials evaluating potential anti-inflammatory, remyelinating or neuroprotective therapies (Miller et al., 2002).

Treatment Of Radiationinduced Late Injury With Ras Blockade

Direct evidence implicating a role for RAS or NADPH oxidase-mediated oxidative stress in radiation-induced late effects is lacking. However, in vitro studies in our laboratory have generated data that suggest a role for both Ang II and NADPH oxidase in the radiation-induced increase in intracellular ROS observed in rat brain microvas-cular endothelial cells in the hours immediately after exposure to radiation. Although a causal link between chronic oxidative stress, the RAS and radiation-induced late normal tissue injury remains to be established, a growing body of evidence supports the hypothesis that chronic oxidative stress in combination with activation of the local tissue RAS may serve to drive the progression of radiation-induced late effects. Indeed, the efficacy of RAS blockers to modulate radiation-induced late effects may also reflect an anti-inflammatory intervention that acts to prevent the propagation and or maintenance of a radiation-induced chronic oxidative stress....

Fish And Omega3 Fatty Acids

The cardioprotective benefits of the 'Mediterranean' diet and its reduction of mortality are strikingly evident in the results of studies such as the DART study (32) and the Lyon Diet Heart Study (33). The results of these studies are not solely due to the regular inclusion of oily fish, but this did have a key role. Oily fish such as mackerel, herring, sardines, trout and salmon are a rich source of the n-3 polyunsaturates. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), the long-chain omega-3 PUFAs, are thought to be beneficial due to their anti-thrombolytic and anti-inflammatory action as well as their triglyceride-lowering effects. The UK Department of Health has recommended to the general population that they consume two portions of fish (100 g or 3-4 oz portion) a week, one of which should be oily (34). People with diabetes should be encouraged to include oily fish in the diet, ideally two to three times a week (35). Fish oils are increasingly available in capsule or...

Inhibition of YSecretase

Although Y-secretase inhibitors have been readily identified from cell-based screens, the finding that this protease mediates the intramembrane proteolysis of a large number of unrelated proteins has raised concern of potential toxic effects, owing to inhibition of the Y-secretase processing of other substrates. However, Lilly have recently reported preliminary safety and tolerability data together with changes in Ap levels for a Y-secretase inhibitor, LY450139 (Siemers et al., 2005), which has now entered a phase II clinical trial. Various other compounds have been identified that also inhibit or modulate Y-secretase activity, including nonpeptidic isocoumarin compounds (JLK inhibitors), STI571 (Gleevec), and nonsteroidal antiinflammatory drugs (NSAIDs) (Beher et al., 2004 Netzer et al., 2003 Petit et al., 2001). Some of these compounds appear to modulate the Y-secretase processing of APP without altering Notch cleavage, raising the possibility of therapeutics that selectively target...

Topical Corticosteroids

Each steroid base, such as prednisolone or dexamethasone, may be available in more than 1 form for example, dexamethasone is available as dexamethasone alcohol or dexamethasone sodium phosphate. The alcohol or phosphate form is known as its derivative. The derivative of the corticosteroid has an important role in both its overall effect and its vehicle. In therapeutic mixtures, acetate and alcohol formulations will form suspensions, while phosphate preparations will remain true solutions. Furthermore, given the same corticosteroid base, acetate preparations have more anti-inflammatory activity than alcohols phosphate preparations are yet less effective. The choice of which steroid to use is made weighing the relative cost, convenience, safety, and effectiveness of the available corticosteroids (Table 7-3) against the patient's condition and need for treatment.

Cyclooxygenase Products

Prostaglandin (PG) D2 is the predominant cyclooxygenase product generated by human mast cells, whereas human basophils do not generate this molecule. The production of PGD2 from PGH2 is glutathione dependent and is blocked by nonsteroidal antiinflammatory drugs and dapsone. It is a potent vasoactive and smooth muscle reactive compound that causes vasodilation when injected into human skin, induces gut and pulmonary muscle contraction, and, in vitro, inhibits platelet aggregation (35). PGD2 is thought to be responsible for flushing and hypotension in some patients with mastocytosis and to be an important mediator of allergic asthma (36). PGD2 is further metabolized to PGJ2, a natural ligand for peroxisome proliferator-activated receptor-g (37), a nuclear receptor important in diabetes and atherosclerosis.

What Does Atrophy Teach Us about the Pathogenesis of MS

Finally, preliminary studies reviewed in the next section suggest that anti-inflammatory therapy may slow the rate of brain atrophy progression during RR-MS, but thus far no study has demonstrated a beneficial effect of anti-inflammatory therapy on atrophy progression in SP-MS. These findings are consistent with the view that atrophy progression is driven to some degree by the inflammatory process in early stages of MS.

Relapsing Remitting MS

Results have been more encouraging with RR-MS trials, where some but not all trials show therapeutic benefits on the rate of atrophy progression. To date, no studies in progressive MS have shown a therapeutic effect of anti-inflammatory therapy on atrophy progression. These results are consistent with the view that inflammation drives atrophy during early stages of MS to a greater degree than later in the disease (Fig. 3).

Alcohol Dependence Sleep and Immunity

Just as sleep can influence cytokine expression, cytokines can affect sleep in alcohol dependence. In clinical studies with alcoholic patients, higher levels of circulating IL-6 before sleep (11 PM) were associated with prolonged sleep latency (Irwin and Rinetti 2004) (Fig. 10.4). In addition, IL-6 is associated with increases in REM sleep during the later half of the night. In contrast, expression of the anti-inflammatory cytokine, IL-10 before sleep predicted increases in delta sleep, accounting for over 23 of the variance in delta sleep independent of age, and alcohol consumption (Redwine et al. 2003).

Salicylates European Pharmacopoeia 231

Salicylic acid and a number of related substances are used in therapy as nonsteroid antiinflammatory drugs. Besides the acetyl ester (Figure 3.28.2) aspirin, 5-amino salicylic acid (Figure 3.28.3) could be mentioned. Salicylic acid is also used for its acidic properties in the treatment of warts because it is a relatively strong organic acid with a pKa of 3. At the present reference to salicylates is made in six monographs including salicylic acid itself and its sodium salt. Being a carboxylic acid, salicylic acid has a water solubility that depends strongly on solvent pH. This, and its well-defined melting point, forms the basis of test (b). In test (a) a strongly colored complex is formed with iron(III).

Subsequent management

Patients with chest injuries require excellent pain control in order to facilitate adequate pulmonary physiotherapy. Adequate pain control alone may improve functional residual capacity and thereby enhance pulmonary function. Dosing of narcotic analgesics on an as-needed basis is a much less effective method of controlling pain than other modalities, such as patient-controlled analgesia. Other methods of pain control, including intrapleural and epidural analgesia, are efficacious in patients with chest injury and avoid some of the systemic effects of narcotics. Non-steroidal anti-inflammatory agents may also be used to supplement the effects of narcotics and allow a lower dose of opiates to be administered.

Interpretation of Test Results

For classic FAP, DNA testing usually is suggested for children at 10 years of age or older, as colon surveillance is recommended to begin at 10 to 12 years of age.1 For individuals at risk for attenuated FAP, colon screening should begin at 18 to 20 years of age and so genetic testing should be offered at that time. There is some debate as to the adequacy of using flexible sigmoidoscopy or if full colonoscopy is required for surveillance. Prophylactic colectomy should be performed to prevent colon cancer after adenomas are identified, but controversy remains regarding the timing and extent of the procedure (ileorec-tal anastomosis or ileoanal pouch anastomosis). If a rectal segment remains after surgery, routine endoscopic screening is required on a biannual basis. The use of oral non-steroidal antiinflammatory Cox-2 inhibitors to prevent or eliminate polyps in the retained rectum has been reported to be effective in the short term but has not been recommended as a means of primary...

Therapeutic Potential of ySecretase Modulators

In contrast, compounds that can modulate the enzyme to alter or block Ap production with little or no effect on Notch would bypass this potential roadblock to therapeutics. Recent studies suggest that the protease complex contains allosteric binding sites that can alter substrate selectivity and the sites of substrate proteolysis. Certain nonsteroidal antiinflammatory drugs (NSAIDs, e.g., ibuprofen, indomethacin, and sulindac sulfide) can reduce the production of the highly aggregation-prone Ap42 peptide and increase a 38-residue form of Ap (Fig. 5) (Weggen et al., 2001). This pharmacological property is independent of inhibition of cyclooxygenase (COX) the Ap modulating effects are seen in COX-1 2 knockout cells and with structurally related compounds that do not inhibit COX. The alteration of the proteolytic cleavage site is observed with isolated or purified y-secretase (Fraering, Ye, et al., 2004 Weggen et al., 2003), indicating that the compounds can interact directly with the...

Evolution of Cortical Visual Evoked Potential Abnormalities after Optic Neuritis

In a minority of cases, visual function remains persistently impaired and VEPs remain attenuated, even after the resolution of inflammation. This can probably be ascribed to axonal damage, although whether it occurs as an intraneuronal process or as a consequence of demyelination and inflammation is unclear. Attempts have been made to discover electrophysiological or anatomical (MRI) factors that may predict a good or poor recovery (Kapoor et al., 1998), so that patients with a poor prognosis might be targeted for treatment, but so far no such indices have been found. In any case, the bulk of evidence suggests that the benefits of anti-inflammatory treatment are transitory, causing an acceler

Project Title Ethnopharmacological Studies In Oral Medicine

Summary (Provided by applicant) Aphthous ulcers and oral pain are considered the most frequent oral ulcerative pathologies of the human species. Oral dermatological conditions, oral cancer and xerostomia are significant related oral pathologies and these conditions also produce significant pain and ulcerative conditions within the oral cavity. Few scientific studies exist which survey, identify and assess, in controlled formats, the efficacy of the various phytomedicines, which are used by humans throughout the planet, for the myriad pain and pathological conditions of the oral cavity. Minimal scientific data are available which identifies the medicinally active compounds and histopathological effects of phytomedicines used as treatments for oral pain, ulcer and cancer pathologies. This proposed project intends to observe, survey and identify, the ethno-pharmaceutical oral medicine practices and oral phytomedicinal preparations used by the indigenous peoples and populations of Costa...

The Rationale for an Immunological Approach to Alzheimers Therapeutics

The Elan-Wyeth clinical trial of their vaccine, AN-1792, was interrupted after 6 of patients developed an aseptic meningoencephalitic syndrome. The majority of patients responded well to steroidal anti-inflammatory treatment, but no further inoculations with the vaccine were performed (Orgogozo et al., 2003).

Corticosteroids In The Treatment Of Multiple Sclerosis

Glucocorticosteroids (GCSs) and adrenocorticotropic hormone (ACTH) are potent immunosuppressive and anti-inflammatory drugs. Since their discovery about six decades ago, GCSs have been used for a variety of human autoimmune disorders including multiple sclerosis (MS). After a clinical relapse, most MS patients will improve to some extent without treatment. Some will be left with clinically detectable neurologic impairment and, after a few relapses, substantial disability may accumulate. The main use of GCS and ACTH in MS has been to treat clinically significant relapses in an attempt to hasten recovery. It is not known if corticosteroids affect the eventual course of MS. The optimal dosage, route of administration, and duration of treatment of corticosteroids remain controversial.

Proton Magnetic Resonance Spectroscopy

1H-MRS detects neurometabolite variation of potential importance in understanding neuronal functioning and status. NAA plays a role in myelin synthesis in the developing brain 3 , has been implicated in lipid repair 4 , has recently been implicated as an antiinflammatory agent 5 , and appears to function as a molecular water pump in active neurons 6 . In the context of brain disorders, reduced NAA has often been construed as reflecting neuronal death 1 however, a recent report of a child entirely lacking the NAA resonance 7, 8 has necessitated an adaptation of this conceptualization to include metabolic dysfunction without neuronal loss per se. The Cho peak reflects MRS-visible choline moieties (phosphocholine, glycerolphospho-choline, choline), likely reflective of tissue synthesis breakdown or inflammatory processes. The Cre peak includes creatine and phosphocreatine resonances, reflective of tissue energetics. An important dimension of difference among MRS studies is whether...

Postoperative Application

Renard et al. (36) compared the effectiveness of subconjunctival injections and collagen shields in delivering anti-inflammatory agents and antibiotics after cataract surgery. The occurrence of folds in Descemet's membrane was less frequent and aqueous flare less severe in the collagen shield-treated group than in those treated with subconjunctival injections.

Other Types of Injuries

Only after excluding bony and ligamentous injury can soft tissue injury to the thoracic spine can be diagnosed. A short course of bed rest and non-steroidal anti-inflammatory agents should precede mobilization with physical therapy. Prolonged pain and discomfort can be evaluated with lateral flexion-extension films to exclude a

Pathophysiology of Diabetes

Type-2 diabetes is characterised by a combination of insulin resistance and defective insulin response that results from it 21 . Blood insulin concentrations are raised, at least initially, but are never sufficient to meet the resistance that entrains them. Like type-1, type-2 diabetes also presents after a variable period of prediabetes, whose presence might be revealed by high fasting insulin glucose ratios and later by glycosuria or hyperglycemia in circumstances which temporarily increase insulin resistance - typically pregnancy, thyrotoxicosis or a course of anti-inflammatory steroids. Between 17 and 63 of women whose glycosuria during pregnancy is attributable to glucose intolerance will subsequently become diabetic, depending on the series quoted 22 . Of these, a proportion (around 20 according to one study 23 ) will develop type-1 diabetes, underscoring the principle to be established here that the prediabetes of type 1 and type 2 differs only in tempo, not in outcome. Both...

Inflammation as an Important Factor in Many Aging Diseases

Chronic inflammation appears an important factor in many of the important diseases of aging. Immunohistochemical evidence for chronic inflammation in affected tissue is seen not only in AD, PD, ALS, and multiple sclerosis but also in other conditions such as atherosclerosis, heart disease, and macular degeneration (Bok, 2005 Kuehn, 2005). Finch (2005), for example, has recently reviewed the remarkable convergence of inflammatory mechanisms in the etiology of cardiovascular disease and Alzheimer disease. The more than 20 epidemiological studies indicating that chronic use of nonsteroidal antiinflammatory drugs (NSAIDs) greatly reduces the risk of AD testifies to the importance of the inflammatory reaction (McGeer & McGeer, 2004a). And recently single epidemiological studies have been published indicating that such use of NSAIDs also reduces the risk of PD (Chen et al., 2003) and macular degeneration (McGeer & Sibley, 2005). Moreover, forms of various

Immunological Factors Cytokines

The knowledge regarding the orchestrated balance of cytokine synthesis and function during pregnancy is evolving on a regular basis. The construal of a working system that explains success or failure of pregnancy is exciting. Although very general, the Th1 (proinflammatory) versus Th2 (anti-inflammatory) working model has been undeniably helpful in understanding immune functioning, particularly in the murine model (Dudley 1996). Although readily applicable to the mouse, it is not as clear-cut in humans. IL-6, for instance, is listed among the proinflammatory cytokines because it is a mediator of host response to tissue damage but it has properties that make it associated with a Th2 (anti-inflammatory) state because it increases IL-4 and IL-10 (Hunt 2000). Despite the prominence of proinflammatory cytokines such as TNF-a, IL-1P, and IL-6 at the beginning and the end of pregnancy, it is currently accepted that Th2-type dominance must occur for a successful pregnancy and that this...

Cyclooxygenase Activity And Expression

Cyclooxygenases catalyze the formation of prostaglandins from arachidonic acid. COX-1 is expressed constitutively as a housekeeping gene in most normal tissues, while COX-2 expression is induced by pro-inflammatory and other mitogenic signals. Aberrant COX-2 upregulation is a common feature of cancer cells and potentially preneoplastic conditions such as tissue inflammation. COX-2 has been causally linked to epithelial tumorigenesis and is under investigation as a target for cancer prevention and therapy (reviewed in Reference 33). COX-catalyzed conversion of arachidonic acid to prostaglandin involves two sequential reactions at spatially distinct active sites, i.e., a cyclooxygenase reaction followed by a hydroperoxidase reaction. In assessing resveratrol as a cancer preventive agent, the Pezzuto team reported that resveratrol inhibited the cyclooxygenase and hydroperoxidase activities of COX-1 but exhibited much weaker effects against COX-2 activity.3 More recently, a detailed...

Antioxidant Strategies In Hypercholesterolemia

Statins were first introduced as lipid-lowering drugs, by virtue of their blocking action on the conversion of HMG-CoA to mevalonoate, the substrate for cholesterol. However, recently, it has become increasingly apparent that statins exert many anti-inflammatory properties that extend beyond their cholesterol-lowering effect. For example, several statins have been shown to increase eNOS expression and subsequently endothelial NO production (67). Furthermore, there is evidence that statins may reduce oxidant production both by preventing enzyme activation, in particular NAD(P)H oxidase activation (68), and by increasing levels of antioxidants such as catalase (55). This would lead to a diminished oxidant stress, and possibly offer an explanation for the ability of statins to attenuate transcription factor activation, reduce CAM expression and cytokine release, and ultimately inhibit leukocyte and platelet recruitment in a cholesterol level-independent manner.

Pregnancy Complications

In an attempt to reduce their frequency, various pregnancy complications or poor outcomes and their potential causes (particularly increased proinflammatory cytokine levels) have been evaluated by researchers. Increased levels of proinflammatory cytokines, such as IL-2, IL-6, TNFa, and IFN-y, have been observed in spontaneous abortions (Clark et al. 1996), recurrent miscarriages (MacLean, Wilson, Jenkins, Miller, and Walker 2002 Raghupathy 2001), and preeclampsia (Afshari et al. 2005 Dekker and Sibai 1999), while anti-inflammatory cytokines, including IL-3, -4, and -10, have been noted to assist in the promotion, establishment, and completion of successful fetal growth (Clark et al. 1996 Dekker et al. 1999 Gaunt and Ramin 2001 Gennaro and Fehder 1996 Hanson 2000 Piccinni et al. 2000 Raghupathy 2001 Sacks, Studena, Sargent, and Redman 1998 Saito, Sakai, Sasaki, Tanebe, Tsuda, and Michimata 1999). It has been suggested that a predominance of proinflammatory cytokines at various points...

Possible Therapeutic Applications of AT for Microcirculatory Disturbances

As described earlier, intravenous administration of AT reduced pulmonary vascular injury and hypotension because of its anti-inflammatory activity in rats given endotoxin, suggesting that AT supplementation might be useful for treatment of acute respiratory distress syndrome and shock associated with sepsis. Administration of AT was also effective in the treatment of ischemia-reperfusion-induced liver and kidney injuries and stress-induced gastric mucosal injury in rats based on its capacity to promote endothelial production of PGI2, suggesting that AT might be useful for treatment of various organ failures associated with circulatory shock. administration of AT significantly improved motor disturbances by inhibiting reduction of the number of motor neurons in rats subjected to transient spinal cord ischemia 10 . Since both local inflammatory responses and spinal cord microinfarction were significantly reduced through increases in spinal cord tissue levels of PGI2 in animals treated...

The splanchnic circulation

Tissues differ in their susceptibility to hypoxia, and a minor oxygen debt for some organs may cause considerable dysfunction in others. The splanchnic organs may be at risk of hypoxia-induced cellular dysfunction for several reasons. The gut does not autoregulate flow for pressure, and gut blood flow falls markedly in response to reductions in cardiac output. Splanchnic vasoconstriction persists despite correction of systemic hemodynamics. The gut mucosa and the renal medulla demonstrate approximately the same vascular architecture of arterioles and venules, allowing oxygen shunting and consequent distal hypoxia under normal conditions. The oxygen content in these vessels is also reduced by plasma skimming, giving a hematocrit of around 10 per cent. This potential for dysoxic damage will be aggravated by alterations in systemic oxygen supply, sepsis-induced changes in tissue perfusion, and certain drugs such as non-steroidal anti-inflammatory analgesics. Because of its main function...

Ts in Microvascular Endothelial Dysfunction

Endothelial cell dysfunction is increasingly being realized as the unifying mechanism of development and progression of chronic diabetic complications. Endothelial cells are critical for a complex array of functions such as providing a barrier between blood and tissues, maintaining growth and phenotypic characteristics of smooth muscle cells, balancing pro- and anti-inflammatory changes, and fluidity of blood. Alteration of endothelial function, therefore, may affect one or more of these properties. In diabetic microan-giopathy, endothelial dysfunction is exhibited as increased permeation, vasoconstriction, and increased synthesis of ECM proteins. Hyalinosis of arterioles and capillaries in diabetes suggests accelerated loss of microvascular endothelial cells and increased ECM deposition. Endothelial degeneration, together with pericyte loss, may bring about a proliferative response and successive elaboration of BM proteins. ETs are implicated in several parameters of microvascular...

The Immune Response To Infection Injury And Inflammatory Agents

The immune system has a large capability for immobilizing invading microbes, creating a hostile environment for them, and bringing about their destruction (1). The immune system may also become activated, in a similar way to the response to microbial invasion, by a wide range of stimuli and conditions that do not directly involve pathogens these include burns, penetrating and blunt injury, the presence of tumor cells, environmental pollutants, radiation, exposure to allergens, and the presence of chronic inflammatory diseases. The response of the immune system to this diverse range of agents and conditions contains many common elements. These, however, vary in intensity according to their impact on the body. The elements of the response include the production of immunomodulatory proteins (cytokines), oxidant molecules (hydrogen peroxide, superoxide, hypochlorous acid, and nitric oxide), anti-inflammatory hormones (cortisol), natural antagonists (cytokine receptor antagonists), and...

Cytokines and Sleep

To date, the majority of studies on cytokines and sleep examined the impact of individual cytokines. However, individual cytokines are only one facet of a complex signaling network. Cells are seldom, if ever, exposed to a single cytokine, but rather experience a changing milieu of proinflammatory and anti-inflammatory cytokines, soluble cytokine receptors, receptor antagonists, hormones, and other inflammatory modulators. Furthermore, the regulation of complex traits such as sleep is itself complex. Therefore, the effects of single cytokines may diverge from those of an array of cytokines. The overall inflammatory milieu is likely to be crucial in determining the sleep response.

Prescription Drug Data

Both generic and proprietary names are used so the ability to differentiate between product types is available. The total amount of drug dispensed is also entered together with the dosing instructions, thus allowing the duration of any prescription to be calculated. Community prescribing data have been entered for selected medications from January 1989 (notably non-steroidal anti-inflammatory drugs, ulcer healing drugs, lipid-lowering drugs and hormone replacement therapy) and all prescribed medications from January 1993. MEMO now has records of 15 million prescriptions dispensed in Tayside up to December 1996.

Immunogenetics In Infectious Diseases Drug Hypersensitivity

Many hypersensitivity reactions appear to be the result of direct activation of the immune system. There is strong evidence for a role of drugs or drug metabolites as antigens or haptens in major histocompatibility complex (MHC)-restricted T-cell activation. Drugs may be conjugated to intracellular proteins and presented by MHC class I or class II molecules to CD8+ or CD4+ T-cells (164). They may also directly alter the MHC-associated peptide complex with subsequent recognition and activation of peptide-specific CD8+ T-cells (165). MHC alleles have been associated with idiosyncratic reactions to nonsteroidal anti-inflammatory agents, pyrazolone derivatives, trimethoprim-sulfamethoxazole, and contact allergens (166-169). Two recent studies used immunogenetics to approach the problem of early, and some times deadly, hypersensitivity reactions to the reverse transcriptase inhibitor abacavir used in the treatment of HIV infection (170,171). The genetic susceptibility to abacavir...

Dualaction Antihistamines

A number of agents currently not available for clinical use in the United States have been discovered to have some clinical effects in addition to their antihistaminic properties. The derivation of these compounds is summarized in TabieS (3,30,31). Although many of their mechanisms of action are unknown, they have been hypothesized to act on mast cells and basophils by preventing calcium influx or intracellular calcium release, which interferes with activation and release of potent bioactive mediators (48,49,50, and 51). Azelastine has been demonstrated to inhibit superoxide generation by eosinophils and neutrophils, which may represent one of its important antiinflammatory mechanisms (52). These drugs can bind to H-, receptors in a competitive and noncompetitive fashion (3,53,54). In addition to their calcium antagonistic activity, they have variable amounts of antiserotonin, anticholinergic, and antileukotriene activities ( 5.5,5.6,5,7,5.8,5.9 and 60).

Summary and Lessons Learned

Randomized clinical trials remain the most robust test of an intervention, and a review of cancer prevention trials provides valuable lessons. In this chapter, we discussed examples of trials that highlight the effects of several prevention modalities on different stages of cancer, from late-stage intermediate endpoints (such as colon polyps) through second primary cancers (such as head and neck tumors). Of the five modalities discussed (diet, pharmacologic agents, selective hormone therapies modulators, nonsteroidal antiinflammatory drugs, and vitamin and mineral supplements), two of the modalities, notably the NSAIDs and calcium supplements, were true successes without significant side effects. Both these interventions were effective at reducing risk of colonic malignancies, perhaps because the colon is an organ with higher cellular turnover in the adult years than other targeted organ sites.104 The other case studies provided examples of either null results, mixed results (i.e.,...

Introduction History and Definitions

The first eicosanoids identified were members of a category known as prostaglandins. Prostaglandins were discovered in the 1930s when a reproductive physiologist, von Euler, observed that a substance in human semen induced contraction of uterine smooth muscle. Because he assumed that the active agent was produced by the prostate gland, he named this substance prostaglandin. Members of the leukotriene family were first identified in the early 1940s as a result of their effects as mediators of anaphylaxis. In 1969, Piper and Vane showed that aspirin inhibited vasoactive substances produced by rabbit aorta, and in 1971, Vane discovered that prostaglandins were the target of nonsteroidal anti-inflammatory drug (NSAID) activity. Samuelsson identified thromboxanes as distinct products in 1979. In the latter half of the 20th century, the recognition of eicosanoids as important mediators of both normal and pathologic physiological responses has added a wealth of data to this increasingly...

Understanding the Side Effects of TNFa Inhibitors

The induction of antinuclear antibodies is common, but rarely associated with clinical manifestations of lupus (Shakoor et al., 2002). A positive connection between TNFa and lupus has been established in lupus mice where the inhibition of TNFa increases incidence and mortality from renal disease (Kontoyiannis and Kollias, 2000). Conversely, administration of TNFa has a protective effect on mouse lupus. The anti-inflammatory cytokine IL-10 is directly involved in the production of autoantibodies and IgG (Llorente et al., 1995). These properties indicate a mutual inhibition between TNFa and IL-10 actions. Furthermore, the inhibition of TNFa favors the production of IL-10, leading to the production of

Obesity and Type 2 Diabetes

A common feature of obesity, insulin resistance, and T2D is chronic, low-grade inflammation (Dandona, Aljada, and Bandyopadhyay 2004 Dandona, Aljada, Chaudhuri, Mohanty, and Garg 2005 Weisberg et al. 2006 Weisberg, McCann, Desai, Rosenbaum, Leibel, and Ferrante 2003 Wellen and Hotamisligil 2005). Markers of chronic subclinical inflammation (e.g., C-reactive protein and IL-6) are closely linked to insulin resistance and obesity (Finegood 2003 Temelkova-Kurktschiev, Henkel, Koehler, Karrei, and Hanefeld 2002). In addition, proinflammatory cytokines such as TNF-a, monocyte chemotactic protein-1 (MCP-1), IL-6, IL-8, and macrophage inflammatory peptide (MIP)-1aare often increased in patients with obesity, insulin resistance and T2D (Gerhardt, Romero, Cancello, Camoin, and Strosberg 2001 Mohamed-Ali et al. 1997 Sartipy and Loskutoff 2003 Takahashi et al. 2003 Uysal, Wiesbrock, Marino, and Hotamisligil 1997 Weisberg et al. 2003, 2006 Xu et al. 2003 Yudkin, Kumari, Humphries, and Mohamed-Ali...

Other Cytokine Inhibitors

As for IL-1 and TNF, IL-6 is highly present in the context of chronic inflammation. There has been some debate on the classification of IL-6 as a proinflammatory or an anti-inflammatory cytokine, and controlling IL-6 as a therapeutic approach was the best way to clarify this issue. For that purpose an

Adverse Effects Contraindications and Drug Interactions

The most immediately serious adverse effect associated with cidofovir therapy is nephrotoxicity. Accumulation of the drug within the proximal tubule epithelial cells can lead to proteinuria, azotemia, glycosuria, elevated serum creatinine, and rarely, Fanconi's syndrome. Probenecid is administered along with cidofovir to block its uptake into the proximal tubule epithelial cells and thereby inhibit its tubular secretion as well as its toxicity. Probenecid carries its own adverse effects, including gastrointestinal upset, hypersensitivity reactions, and a decrease in the elimination of drugs that also undergo active tubular secretion (e.g. nonsteroidal antiinflammatory drugs NSAIDs , penicillin, acyclovir, zidovudine).

Non Related Neurotransmitters

Acetylcholine is found in animals, plants and bacteria 164 . In humans, acetylcholine is an important neurotransmitter, but it also plays a role in nonneural tissues including epithelial and endothelial cells as well as leukocytes 164 . Receptors for acetylcholine are divided in two groups according to their binding of the plant alkaloids nicotine and muscarine 165 . Nicotinic acetylcholine receptors (nAChR) are pentameric cation channels, and muscarinic acetylcholine receptors (mAChR) are GPCRs. Lymphocytes express both of these receptor subtypes, contain and release acetylcholine, and express the choline acetyltransferase which is the enzyme that generates acetylcholine 166, 167 . Acetylcholine regulates the function of NK cells and lymphocytes 168 . Engagement of nAChR leads to the release of the proinflammatory chemokine interleukin-8 from neutrophil granulocytes 169 , and leads to proinflammatory responses in macrophages 170 , although the cholinergic system in leukocytes is in...
