chronic granulomatous disease

Definition: a congenital defect in the killing of phagocytosed bacteria by polymorphonuclear leukocytes, which cannot increase their oxygen metabolism due to dysfunctional NADPH oxidase, either because of defective cytochrome [MIM*233710 and MIM*233690] or other specific factor deficiencies [MIM*233700 and MIM*306400]. As a result there is an increased susceptibility to severe infection by catalase-positive microorganisms; inheritance is usually autosomal recessive or X-linked.

Synonym(s): congenital dysphagocytosis, granulomatous disease
