Clinical features

Bacterial infections—recurrent chest infections (may lead to bronchiectasis), sinus, skin and urinary tract infections common. Fulminant viral infections, especially measles, varicella.


• May improve with treatment of the underlying disease.

• IVIg should not be used routinely as prophylaxis.
