Summary

Hepatopulmonary syndrome (HPS) is a frequent pulmonary complication of end-stage liver disease that is characterized by decreased arterial oxygenation caused by intrapulmonary vascular dilatation. Due to the different diagnostic criteria used in different studies, its prevalence ranges from 4% to 47% in patients with cirrhosis. Main underlaying pathogensis for HPS being activation of macrophages which are responsible for iNOS, PDGF and VEGF release contributing to development of intrapulmonary vascular dilatation(IPVD) , and neoangiogenesis leading to anatomical shunt resulting decreased oxygenation. Sphingosine 1 phosphate (S1P) is an essential compound produced and secreted by endothelial cells, platelets and RBC's. S1P prevents adhesion, transmigration and release of inflammatory mediators from macrophages. S1P levels are decreased in cirrhotics. Simvastatin, a HMG CoA inhibitor has many pleotropic effects, Of which one is by agonizing the S1P response and improving oxygenation in HPS patients. Simvastatin at a optimal dose of 40mg/day for 6months. Pre and post simvastatin treatment related oxygenation changes and concurrently its effect on liver fibrosis will be evaluated.
