The antifibrotic potential of a sustained release formulation of a PDGF beta-receptor targeted rho kinase inhibitor

2019

Rho kinase activity in hepatic stellate cells (HSCs) is associated with activation, transformation and contraction of these cells, leading to extracellular matrix production and portal hypertension in liver cirrhosis. Inhibition of rho kinase activity can reduce these activities, but may also lead to side effects, for instance systemic hypotension. This can be circumvented by liver-specific delivery of a rho kinase inhibitor to effector cells. Therefore, we targeted the rho kinase inhibitor Y27632 to the key pathogenic cells in liver fibrosis, i.e. myofibroblasts including activated HSCs that highly express the PDGF beta-receptor, using the drug carrier pPB-MSA. This carrier consists of mou…

Effects of Eradicating Hepatitis C Virus Infection in Patients With Cirrhosis Differ With Stage of Portal Hypertension.

2016

Clearance of hepatitis C virus (HCV) via antiviral treatment changes the course of liver disease. We evaluated the benefit of sustained virologic response (SVR) in patients with HCV and cirrhosis without (stage 1) and with (stage 2) esophageal varices (EV).We performed a prospective cohort study of 444 patients with HCV and compensated cirrhosis (218 with stage 1 and 226 with stage 2 disease) treated with peg-interferon and ribavirin from June 2001 through December 2009 at the University of Palermo, Italy and followed for a median of 7.6 years (range, 1-12.6 years). We used Cox regression analysis to identify variables associated with appearance or progression of EVs, development of hepatoc…

Baveno VII – Renewing consensus in portal hypertension

2022

To expand on the work of previous meetings, a virtual Baveno VII workshop was organised for October 2021. Among patients with compensated cirrhosis or compensated advanced chronic liver disease (cACLD – defined at the Baveno VI conference), the presence or absence of clinically significant portal hypertension (CSPH) is associated with differing outcomes, including risk of death, and different diagnostic and therapeutic needs. Accordingly, the Baveno VII workshop was entitled “Personalized Care for Portal Hypertension”. The main fields of discussion were the relevance and indications for measuring the hepatic venous pressure gradient as a gold standard, the use of non-invasive tools for the …
