Chronic granulomatous disease (CGD) is a genetic immunodeficiency characterized by dysfunctional phagocytes.
WHAT CASUES IT?
CGD is most often cause by a gene defect in the NADPH oxidase enzyme complex. This leads to the inability to form hydrogen peroxide, and caused impaired intracellular killing by phagocytes.
WHAT MAKES US SUSPECT IT?
Family history (most cases X-linked recessive)
- Recurrent pulmonary/cutaneous infections
Leukocyte, platelet, B cell, and T cell concentrations are all NORMAL in patines with GCD.
Neutrophil function testing:
- Dihydrorhodamine 123 test
- Nitroblue tetrazolium test
