Comparison of the efficacy of triple blockade, double blockade and single blockade of RAAS in non diabetic chronic kidney disease

ABSTRACT

Background: Although dual blockade of the renin-angiotensin-aldosterone system with the combination of an angiotensin-converting enzyme inhibitor and angiotensin II receptor blocker is generally well established as a treatment for nephropathy, this treatment is not fully effective in some patients.Methods: A prospective observational study was done on 600 chronic kidney disease patients during July 2012 to August 2014 to compare the efficacy of triple blockade, double blockade and single blockade of renin-angiotensin-aldosterone system in non diabetic chronic kidney disease.Results: At the end of the study, 24 hours urinary protein excretion rate of group I and group III were compared by using student t-test and p value (0.0268) was found significant. Similarly, on comparing group II and group III, p value (0.0160) was again found significant.Conclusions: Triple blockade of the renin-angiotensin-aldosterone system was effective for the treatment of proteinuria in patients with non-diabetic nephropathy whose increased urinary protein had not responded sufficiently to a dual blockade.
