Renal Data from Asia - Africa: End-stage renal disease in Nigeria: an overview of the epidemiology and the pathogenetic mechanisms

There is paucity of information on the magnitude of the burden of renal disease in our environment. Obtaining accurate data is hampered by the poor socioeconomic status of most patients with lack of access to specialized care in tertiary institutions,where most of the data is generated. The incidence of chronic renal failure (CRF) and end-stage renal disease (ESRD) in any specified area is known to be influenced by the prevalence of specific disease entities resulting in CRF. Hypertension,glomerulonephritis (GN),sickle cell disease,quartan malaria nephropathy,urinary tract schistosomiasis and other parasite-related forms of chronic GN are known to contribute significantly to the incidence of CRF in Nigeria. As is the situation in other parts of the world,diabetic nephropathy appears to be of increasing importance in the causation of ESRD in Nigeria. Even though the underlying cause of renal disease can often not be treated,extensive studies in experimental animals and preliminary studies in humans suggest that progression in chronic renal disease may largely be due to secondary factors,attention to which may be important in the prevention and/or control of renal disease.
