[Hypertension and primary glomerulonephritis in adults. A study of 302 cases].

The purpose of the present work was to show the place of hypertension in primary glomerulonephritis in adults. Hypertension was defined as diastolic blood pressure above 90 mmHg and renal insufficiency as serum creatinine above 135 mc mol/L. Secondary glomerulonephritis was excluded. The study was performed in 302 patients with primary glomerulonephritis biopsied between March 1994 and March 1996. They were 183 males and 119 females, aged from 16 to 63 years (mean: 29.8 years). The incidence of hypertension at the time of admission was 46.6%: 141/302 cases. The only consideration of prolonged hypertension (excluded transient hypertension of acute nephritic syndrome) shows an incidence of 31.4%: 95/302 cases (table). Frequency of hypertension (HT) in different types of primary glomerulonephritis (GN): [table: see text] The histological types observed in these cases of hypertension were represented essentially by the proliferative lesions: 73% (72/95 cases) who were grouped mainly in proliferative glomerulonephritis postinfectious and IgA nephropathy. No proliferative lesions: 24% (23/95 cases) were especially represented by focal segmental sclerosis. Renal insufficiency noted in 69 cases on 95 hypertensions was probably the result of the parallel evolution of hypertension renal lesions and those belonging to these histologic types. In conclusion, this study shows a narrow correlation between the hypertension and proliferative glomerulonephritis in our young adults population.
