Summary: There were 2758 biopsies of glomerulonephritis diagnosed in the Department of Pathology in the 20 years from 1976 to 1995. Of these 1893 (76.1%) were of primary glomerulonephritis while 577 (23.2%) were of secondary glomerulonephritis. Immunofluorescence studies were available in 1494 (80%) cases. Predominantly mesangial IgA staining was seen in 49.1% of cases, thus identifying them as IgA nephropathy. Mesangial glomerulonephritis was found in 79.1% of cases whilst 17.7% had sclerotic lesions either focal or global. One hundred and fifty-one patients were followed up. Of these, 98 (65%) were detected through health screening while 53 (35%) presented with symptoms. Uncontrolled hypertension, proteinuria of more than 2 g, the presence of crescents and glomerulosclerosis on biopsy were unfavourable prognostic factors. Hypertensive patients also had a higher incidence of medial hyperplasia of the blood vessels. However IgA nephropathy is a benign disease with a cumulative renal survival of 91% after 6 years. |
