Angiotensin converting enzyme inhibitors (ACE-i) and angiotensin II receptor blockers (ARB) are considered to be equally effective for patients with diabetic kidney disease, while only ACE-i have been shown to determine a significant reduction in the risk of all-cause mortality, predominantly cardiovascular, in these patients. Studies on the cardio-renal efficacy of combined therapy with ACE-i and ARB are not available or not conclusive, in a population with cardiovascular risk with micro- or macroalbuminuria. In this paper, we present the protocol of a randomized controlled clinical trial that will address the question. The LIRICO (Long-term Impact of RAS Inhibition on Cardiorenal Outcomes) study will evaluate the comparative efficacy for cardiovascular and renal outcomes of combined therapy with ACE-i and ARB versus monotherapy with ACE-i or ARB in micro/macroalbuminuric individuals at cardio-renal risk. The study will enrol 2100 patients allocated to monotherapy with ACE-i, ARB or combined treatment with ACE-i + ARB. The LIRICO study is a randomized comparative trial, with PROBE (Prospective Randomized Open Blinded End-Point) design. The study has been approved and funded by the Agenzia Italiana del Farmaco (AIFA) within the 2005 funding plan for independent research on drugs. Availability of funding for this study provides, for the first time in our Country, an opportunity to organize a collaborative national network of nephrology, internal medicine and diabetology outpatient clinics to develop a large multicentre trial collaboration. The results of this trial will establish the optimal therapy for micro/macroalbuminuric individuals with cardiovascular and renal risk.
