Abstrakt: Background/aims: Pharmacological inhibition of renin-angiotensin-aldosteron system (RAAS) may reduce proteinuria and the rate of chronic kidney disease progression. The aim was to compare the effects on albuminuria of the therapy with either: (i) telmisartan 80 mg and aliskiren 300 mg, (ii) telmisartan 80 mg and eplerenone 50 mg, (iii) telmisartan 160 mg as monotherapy.
Design and Patients: Randomized, double-center, double-blind, cross-over, three treatments-three periods of 8 weeks each study. 18 patients with non-diabetic proteinuric CKD stage 1-3 completed the protocol.
Results: There was significant difference in albuminuria between studied therapies (ANOVA; p<0.01). The combination therapy with telmisartan plus aliskiren decreased albuminuria more effectively than the treatment with telmisartan plus eplerenone and monotherapy with telmisartan 160 mg OD [376 mg/g creatinine (286-686) vs. 707 (502-1204) vs. 525 (318-763); post-hoc p<0.01 and p<0.05, respectively].
Conclusions: The study demonstrated that the combination therapy with angiotensin receptor blocker (ARB) and renin inhibitor was more effective in albuminuria lowering than the concomitant usage of ARB and mineralocorticoid receptor antagonist as well as than ARB in doses two-fold higher than usually used in treatment of hypertension in patients with non-diabetic CKD and that this higher antiproteinuric efficacy was independent on changes in blood pressure.
