Hypertension in IgA nephropathy.
Abstract
Among 151 patients with IgA nephritis, 18/151 (12%) had hypertension at presentation and 50/151 (33%) were hypertensive after an interval of 65 +/- 40 (Mean +/- SD) months. Hypertensive patients (n = 50) had a higher incidence of glomerulosclerosis, medial hypertrophy of blood vessels, tubular atrophy, poorly selective proteinuria and extension of immunodeposits to peripheral capillary walls compared to normotensive patients (n = 101). Chronic renal failure occurred more commonly among hypertensives compared to normotensive patients (42%) versus 14%. However, the time taken for patients to reach renal impairment or end stage renal failure was not significantly different. The cumulative renal survival for the hypertensive group was 78% after 8 years compared to 91% in the normotensive group (p less than 0.05). In the second part of the study, patients who were hypertensive at presentation (n = 18) were compared with those who developed hypertension on follow up (n = 32). Apart from a shorter duration of follow up for patients with hypertension and a higher incidence of glomerulosclerosis, there were no significant differences in their clinical presentation, laboratory indices or other histological parameters. The incidence of chronic renal failure and the time taken to reach end stage renal failure were not different. Uncontrolled hypertension was an important cause for rapid deterioration to end stage renal failure within 3 years, compared to 8 years when hypertension was controlled.
