Clinical features and course of IgA glomerulonephritis.

Abstract

A review of the clinical features, laboratory findings and course in 50 cases of IgA glomerulonephritis confirmed by biopsy is presented. The onset and clinical course of the process was oligosymptomatic in the majority of the cases with a predominance of microhematuria and persistent proteinuria. By the end of the observation period more than 50 per cent of the patients became hypertensive and in 16 cases serum creatinine levels attained 132 mumol/l (1.5 mg per 100 ml) or more. Proteinuria in excess of 1 g/24h, hypertension and an impaired concentration capacity at the onset heralded early progression.
