The spectrum of glomerular diseases in the kingdom of bahrain: an epidemiological study based on renal biopsy interpretation.
Glomerular diseases continue to be the leading cause of end-stage renal disease globally. Hence it is important to recognize the glomerular disease pattern in any given geographical area to understand the pathobiology in the region as well as the incidence and progression of the disorder. A total of 498 renal biopsies were performed on patients with proteinuria, hematuria, and mild to moderate renal impairment during a period of 13 years (between January 1990 and December 2002) at a tertiary care hospital. Primary glomerular disease accounted for two-thirds of the glomerular diseases, which was 44.8% of all renal biopsies. The most common histological lesion was minimal change disease (30%). Focal segmental glomerulosclerosis was the second most common lesion (23.8%) followed by membranoproliferative glomerulonephritis (14.3%). Secondary glomerular disease included 33.6% of glomerular diseases with 22.7% with lupus nephritis as the commonest lesion (38.9%) followed by diabetic nephropathy (31.9%) and hypertension (20.4%). Tubulointerstitial diseases accounted for 13.1% of all renal biopsies, whereas transplant diseases were noted in 12.2%. The miscellaneous group including inadequate biopsies, which constituted 7.2% of all the tissues. The results of this analysis were compared with surveys from other parts of the world.
