Abstract:
OBJECTIVEChronic granulomatous disease (CGD) is a rare primary immunodeficiency of phagocytic oxidative bursts leading to recurrent severe bacterial and fungal infections as well as granuloma formation. There were few reports on the clinical characteristics of this disease in China. The purpose of this study was to evaluate the clinical features of 48 Chinese cases with CGD which were confirmed by clinical features, dihydrorhodamine (DHR) assay and gene mutation analysis.
METHODThe study cohort was the population of CGD patients diagnosed in Children's Hospital of Fudan University from January, 2004, to June, 2011. Cases included in our analysis were restricted to those who had complete data of the clinical symptoms and laboratory tests. The patients were followed up by outpatient visiting and telephone call regularly for 0.5 to 6 years. The history and data of physical examination and treatment of 48 cases were collected and reviewed.
RESULTAll the patients were diagnosed by DHR analysis. The age of onset of all the 48 patients were less than 6 months, including 43 male and 5 female. The mean age at diagnosis was 2.42 years; 12 patients were infants under six months, 10 were between 6 and 12 months, 9 were between 1 and 2 years, 5 patients were between 2 and 3 years, 4 were between 4 and 5 years, and 8 were between 6 and 10 years. Recurrent respiratory infection (44/48) and chronic diarrhea (31/48) were the common symptoms in all the patients, and then skin lesion (22/48), including marked reaction at BCG infected site, pustular eruption and infected skin ulcer and urinary tract infection (3/48) were also general symptoms in our study. In addition, lymphadenectasis occurred in 31 cases and 23 of them were considered to be associated with BCG vaccination. The pathogens caused the infection were mycobacteria (52.08%), fungi (43.75%) and pyogenic bacteria. Thirty-seven patients had mutations in CYBB/CYBA/NCF1/NCF2 genes. Recombinant human interferon-gamma (rhIFN-γ) plus sulfamethoxazole were used for the prevention and treatment of infection, the frequency and severity of the disease could be reduced.
CONCLUSIONThe age at onset and diagnosis of the present group of CGD was younger. Clinical symptoms were associated with recurrent mycobacterial, fungal and pyogenic bacterial infection, which involved respiratory tract, alimentary tract, skin and lymph node. rhIFN-γ partially improved the prognosis of CGD.
