Sixty-six cases of acute post-infectious glomerulonephritis, 31,4% of all glomerulopathies diagnosed in our Service were studied. Patients were classified according to the presence (33,3%), or not (66,7%) of arterial hypertension during the acute phase of disease. As far as clinical and analytical data are concerned, the more symptomatic forms were observed among cases with arterial hypertension. However, after the acute phase of disease clinical evolution was similar in both groups.
