RESUMO
Despite the frequency of sickle cell disease (SCD) in the West African population, the renal changes and outcome associated with it have been poorly characterized. We retrospectively studied 22 renal patients; 19 heterozygous sickle cell trait (AS) and three homozygous (SS) evaluated between 1996-2002. The mean age was 43 years (range from 19-69 years). The observed nephropathies included chronic glomerulonephritis (CGN) in eight (36.3%) cases, advanced chronic renal failure (CRF) in seven (31.8%), chronic tubulointerstitial nephropathy (CTIN) in four cases (18.1%), post-infectious acute glomerulonephritis (AGN) in two(9.1%) cases and pregnancy related nephropathy in one (4.5%) case. Renal biopsy was performed in five (22.7%) patients (three AS and two SS patients); the findings included membranoproliferative glomerulonephritis (MPGN), CTIN, focal and segmental glomerulosclerosis (FSGS) and membranous glomerulonephritis. We conclude that there are various renal abnormalities associated with SCD and optimal management needs early diagnosis and multidisciplinary follow-up.
