The occurrence of alterations was verified in some parameters of the assymptomatic individuals' renal function infected by the virus of the human imunodeficiency (HIV). Forty seven individuals were studied, taking place renal functional tests, as: creatinina clearance, clearance of free water, clearance osmolar, reabsorption tubular proximal and distal of sodium and potassium and urinary pH. The results revealed significant differences (p < 0.05) in the urinary pH, larger in the group with HIV (6.36 ± 0.41), that in the controls (6.02 ± 0.41); in the clearance of free water, that indicated reabsorption of larger water in the group with HIV (1.00 ± 0.64ml/min) and in the clearance osmolar, that was 2.00 ± 0.83ml/min in the group with HIV and 1.57 ± 0.48ml/min. The remaining of the indicators of renal function was not shown statisticaly different between an and other group. It was ended that those differences are significant, in spite of the absolute values they be inside of the normality, because could be associated to late evolutionary alterations of the disease, such as the increase of the frequency of infections of the urinary treatment and the hyponatremia dilucional. More studies are necessary for if they confirm those hypotheses.
