Chronic granulomatous disease: a case report
1Department of Pediatrics, Taichung Veterans General Hospital, Taiwan, ROC.
Insights
Chronic granulomatous disease (CGD) is a rare inherited disorder affecting phagocytic leukocytes. Early diagnosis and antimicrobial prophylaxis are crucial for managing recurrent infections in CGD patients.
Area of Science:
- Immunology
- Genetics
- Pediatrics
Background:
- Chronic granulomatous disease (CGD) is a rare inherited immune deficiency.
- It results from defects in the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex.
- Phagocytic leukocytes in CGD patients cannot produce sufficient reactive oxygen species to kill microbes.
Purpose of the Study:
- To present a typical case of CGD in a young boy with recurrent infections.
- To highlight the importance of considering CGD in the differential diagnosis of such cases.
- To review recent advances in the diagnosis and management of CGD.
Main Methods:
- Case report of a young boy with recurrent perianal abscess, osteomyelitis, and bacterial enterocolitis.
- Flow cytometric analysis of neutrophil respiratory burst pathway.
- Literature review on CGD diagnosis and management.
Main Results:
- The patient presented with symptoms consistent with CGD.
- Flow cytometry confirmed defects in the neutrophil respiratory burst pathway.
- The carrier status of the mother and younger sister was identified.
- Antimicrobial prophylaxis led to a well clinical outcome for the patient.
Conclusions:
- CGD should be considered in children with recurrent severe infections.
- Accurate diagnosis through methods like flow cytometry is essential.
- Prophylactic antimicrobial therapy is effective in managing CGD and preventing infections.
Abstract:
Chronic granulomatous disease (CGD) is a rare inherited disorder caused by defects in the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex of phagocytic leukocytes. The leukocytes of the CGD patients cannot produce adequate amount of superoxide and other oxygen metabolites which are toxic to microorganisms. As a result, the phagocytes fail to kill the ingested microorganisms, especially those with catalase activity. Typically, CGD patients suffer from recurrent pyogenic infections starting from the first year of life. We report a young boy who had experienced recurrent perianal abscess, osteomyelitis and bacterial enterocolitis. Flow cytometric analysis revealed defects in the neutrophil respiratory burst pathway and defined the carrier state of his mother and younger sister. He received antimicrobial prophylaxis at our out-patient clinics and remained well at present. We try to make clinical physician keep in mind the diagnosis of CGD by presenting this typical case. In the meantime, we review the recent literature regarding the advances in diagnosis and management of CGD.
