Chronic granulomatous disease (CGD) is one of congenital immunodeficient disease and a rare X-linked or autosomal recessive disease characterized by recurrent life- threatening infections and granuloma formation. We observed clinical features, laboratory findings and genetic subgroups of 33 children who were diagnosed with chronic granulomatous disease in the Department of Pediatrics, Seoul National University Children's Hospital. There were 23 males and 10 females. Activated NBT test of all patients revealed 0% positive cell and mothers of 15 patients had 25%- 75% normal neutrophils in the activated NBT test. According to the result of activated NBT test and family history, the ratio of X-linked and autosomal recessive inheritance was 2:3. There was a significant difference for the age at onset of the first infection in the different genetic subgroups. The X-linked group had the mean onset at 1.98 months of age and autosomal recessive group had a mean onset as late as 3.82 months (p<0.05). The most common type of the first infection was lymphadenopathies (41%) and other infections were skin pustules, fever, perianal abscess, pneumonia and chronic diarrhea. However, the age at diagnosis was not significant in the different genetic subgroups. Lymphadenitis (27%) was the most common infection, and pneumonia, gastrointestinal tract infection, skin infection were also common. The most common infectious agent was Candida sp. (5%) and other microorganisms involved were BCG, coagulase-negative staphylococcus, S. aureus, K/ebsiella pneumoniae, Aspergi/lus sp., and Enterococcus faecium. Chronic condition associated with CGD were hepatomegaly (59%), splenomegaly, and anemia of chronic disease, underweight, and lymphadenopathy. The leukocyte count of patients at diagnosis was within normal limit except in three patients and leukopenia was not observed in any of the patients. The humoral and cellular immunity and complement system were normal, but the level of Ig E in four patients was elevated. Early diagnosis of CGD can be made by suspicion if there are lymphadenitis after BCG vaccination and recurrent pyogenic infections under the first year of age. Though progression in the treatment of CGD, like gene therapy, is concerned, genetic counseling and prenatal diagnosis by carrier detection and molecular genetic analysis is thought to be necessary.
