Why is there so much end-stage renal failure of undetermined cause in UK Indo-Asians?
There is a high incidence of end-stage renal failure (ESRF) of undetermined cause in the Indo-Asian population of the UK. We studied patients presenting from the district of Brent and Harrow, which has a large Indo-Asian community, and whose renal services are largely provided by our centre. The diagnosis and ethnicity of patients starting renal replacement therapy and/or undergoing renal biopsy were collated. The incidences of ESRF, rates of renal biopsy and underlying diagnoses were calculated for Indo-Asians and Caucasians. Requirement for renal replacement therapy in Indo-Asians presenting to our centre from Brent and Harrow was 221/10(6)/year; no underlying diagnosis was identified in 77/10(6)/year. Renal biopsy rate in these patients was 456/10(6)/year, and the diagnostic categories significantly over-represented compared to Caucasians were: hypertension and ischaemia, focal segmental glomerulosclerosis (FSGS), idiopathic interstitial nephritis (IIN), diabetic nephropathy, minor
