Abstract

There is general agreement that hypertension is a prognostic index of the progression of chronic renal insufficiency (CRI), although it remains to be clarified whether this is related to the hypertension per se, or to the underlying disease and the level of CRI. In an attempt to clarify this important point, an inductive analysis was made of the behavior of blood pressure values and their relationship to the progression of CRI in 456 patients (pts) who participated in a multicenter prospective formal randomized trial, designed to compare the effects of a restricted and a controlled protein diet on CRI progression. An analysis was also made (on the population as a whole and by separating the pts into fast progressive and slowly progressive groups) of the type and frequency of the anthypertensive drugs used, the number and type of drugs used in association, and their possible relationship to the progression of CRI. Of the 456 enrolled pts, 406 (89%) were defined as hypertensive at entry (mean blood pressure 〉 107 mm Hg); 324 out of the 380 pts (85.3%) who completed the 24-month follow-up or reached an end point were treated with anthypertensive drugs. There was a significant difference at entry between the supine blood pressure values of the pts with fast progressive CRI (182 pts), and those of the pts with slowly progressive CRI (198 pts). During the follow-up period, no significant differences were observed between the two groups. There was no difference in the blood pressure levels reached with the different drugs used. The results of our trial seem to give some support to the idea that hypertension may affect the progression of CRI, but the hypothesis that a reduction in blood pressure levels leads to a slowing down in the progression of CRI remains to be clarified. © 1993, National Kidney Foundation, Inc..
