Renal Data from the Arab World: A five-year analysis of the incidence of glomerulonephritis at Cairo University Hospital-Egypt

Our study aimed to obtain a comprehensive review of the incidence of biopsy-proven glomerulonephritis (GN) at the Cairo University Hospitals,Egypt,over the last five years. We analyzed the clinical and pathological data of all renal biopsy samples that were performed during the period from July 2003 to July 2008. Renal biopsy samples of 924 patients were referred for pathological assessment during the period of the study [437 male and 487 female patients; their mean age was 26.5 ± 14.6 years (range: 2.5-71 years)]. Focal segmental glomerulo-nephritis was the most frequent cause of primary GN (21.21%),followed by mesangial proliferative GN (18.93%), diffuse proliferative GN (13.96%),focal proliferative GN (12.77%) and membranous GN (10.93%). The results could be explained by the high incidence of lupus nephritis among the study subjects as well as the relatively young age of the study group.
