Abstract

Chronic granulomalous disease (CGD) is a rare genetically determined immunodeficiency. Neutrophils from CGD patients show a defective killing of phagocytosed fungi and bacteria, due. not only to an impairment in oxidative burst, but also to absence of normal pH value within phagocytic vacuole following phagocytosis. Because a weak base such as amantadine could potentially reverse these pH abnormalities, the authors used this drug to treat 2 CGD patients. They observed modifications of both phagosomal pH and killing activity on. their neutrophils compared to those of healthy controls. Since the drug has been employed, the patients have not developed new infections, suggesting a role of amantadine as a part of CGD prophylactic regimen. These results suggest the opportunity of testing the drug in larger studies.
