Chronic granulomatous disease of childhood
Insights
Recurrent severe bacterial infections in three children were linked to chronic granulomatous disease, a condition affecting neutrophil function. Genetic testing confirmed a sex-linked inheritance pattern in one case.
Area of Science:
- Immunology
- Genetics
- Pediatrics
Background:
- Recurrent severe bacterial infections can indicate underlying immunodeficiencies.
- Chronic granulomatous disease (CGD) is a primary immunodeficiency characterized by defective microbial killing by phagocytes.
Abstract:
Two boys and one girl suffering from recurrent severe bacterial infections were investigated. All 3 exhibited normal cellular and humoral immunity, normal neutrophil phagocytic ability, and defective neutrophil bacterial capacity. The clinical features and laboratory findings in these patients are diagnostic of chronic granulomatous disease. A sex-linked inheritance pattern was confirmed in 1 patient by the demonstration of a heterozygous carrier state in the mother.
