Study About Simvastatin in Portal Hypertension in Compensated Cirrhosis (SIMPRO)

Prevention of Progression of Portal Hypertension in Compensated Cirrhosis Using Selective Hepatic Vasodilators. A Double-blind, Multicenter,Randomized Controlled Trial

The purpose of this study is to determine whether simvastatin is effective in the prevention of progression of porta hypertension in compensated cirrhosis patients.

Detailed Description

Decompensation of cirrhosis is associated with a dramatic reduction of survival. Progression of portal hypertension (PHT) is the main determinant of decompensation that appears when portal pressure gradient (PPG) is ≥10mmHg (clinically significant HTP). 40% of compensated cirrhotic patients have mild PHT. However, with progression of disease 41% develop clinically significant PHT. In cirrhosis, PHT results from increased resistance to blood flow, with a dynamic component due to decreased nitric oxide (NO) bioavailability. In advanced disease increased portal venous inflow also contributes to PHT. Beta-blockers have not been useful in compensated cirrhosis with mild PHT. In early cirrhosis, vasodilators may be more adequate. Statins, drugs that inhibit the activity of HMG-CoA reductase, induce selective hepatic vasodilation due to an enhanced bioavailability of NO. Acutely, they decreases hepatic resistance, while with long-term use statins decreases PPG without deleterious effects on systemic circulation. This multicenter, randomized, double-blind placebo-controlled study is aimed at assessing whether treatment with simvastatin may prevent progression of mild PHT (with PPG between 6 and 10 mmHg) to clinically significant PHT. Patients with compensated cirrhosis, without previous decompensation, without esophageal varices at risk and with PPG between 6 and 10 mmHg will be included. The calculated sample size is 80 patients and the duration of the study 4 years (2 years including and a follow-up of at least 2 year).
