IgA nephropathy in Malaysia.

A total of 164 patients with IgA nephropathy were diagnosed at the Department of Medicine, Universiti Kebangsaan Malaysia and the Department of Nephrology, General Hospital, Kuala Lumpur between 1981-1988. This represented an incidence of 20.1% of all primary glomerulopathies seen in both units. The 3 major ethnic groups were equally affected with 59.7% occurring between the ages of 20-36 years. It was not uncommon in females. The high prevalence of hypertension, renal failure, heavy proteinuria at presentation and the increased chronicity index in the biopsy, suggest that IgA nephropathy is progressive disease leading to chronic renal failure.
