Chronic Granulomatous Disease: a Cohort of 173 Patients—10-Years Single Center Experience from Egypt

PURPOSE: Chronic granulomatous disease (CGD) is an inherited primary immunodeficiency disorder of phagocytes, characterized by recurrent fungal and bacterial infections. Our aim is to describe the different clinical presentations, non-infectious auto-inflammatory features, types and sites of infections, and to estimate the mortality among our large cohort. METHODS: This is a retrospective study conducted at the Pediatric Department of Cairo University Children’s Hospital in Egypt, including cases with a confirmed CGD diagnosis. RESULTS: One hundred seventy-three confirmed CGD patients were included. AR-CGD was diagnosed in 132 patients (76.3%) including 83 patients (48%) with p47(phox) defect, 44 patients (25.4%) with p22(phox) defect, and 5 patients (2.9%) with p67(phox) defect. XL-CGD was diagnosed in 25 patients (14.4%). The most common recorded clinical manifestations were deep-seated abscesses and pneumonia. Gram-negative bacteria and Aspergillus were the most frequently isolated species. Regarding the outcome, 36 patients (20.8%) were lost from follow-up. Among patients with known outcome, 94/137 patients (68.6%) are living, while 43/137 patients (31.4%) died. CONCLUSION: AR-CGD is predominant in Egypt; CGD must always be ruled out in any patient presenting with typical or atypical mycobacterial or BCG-disease.
