Dynamics of Fibrotic Changes in the Liver After the Successful Eradication of Hepatitis C Virus in Patients With Nafld

Abstract

The aim: To assess the dynamics of serum levels of angiopoietin-2 and transforming growth factor-β1 in patients with chronic hepatitis C (CHC) with concomitant nonalcoholic fatty liver disease (NAFLD) after successful DAAs. Materials and methods: 82 patients with CHC were examined, of which 56 were diagnosed with NAFLD and increased body weight. Ang-2, TGF-β1, leptin, adiponectin, and the degree of liver fibrosis were determined for all participants. The patients were divided into groups: 1 gr. (n=23) – CHС + increased body weight + hepatic steatosis, 2 gr. (n=33) – СНС + increased body weight + nonalcoholic steatohepatitis, 3rd gr. (n=26) – CHC. All patients received DAAs for 12 weeks. Results: From 82 patients F3-4 had 31 people, F1-2 – 25, F0-1 – 11, F0 -15 patients. F3-4 and steatosis S2-3 (p<0.05) was more common in patients of 2 gr.. Serum Ang-2 levels were higher (p<0.05) in patients of 2 gr. with F3-4, than in patients with F0-2. Fibrosis regression occurred more often in patients with 1 and 3 gr. with F1-2 than in patients 2 gr. and F3-4 and was accompanied by a decrease in Ang-2 and TGF-β1 levels. Conclusions: High levels of Ang-2 and TGF-β1 are registered in patients with CHC+NAFLD, which correlate with the degree of liver fibrosis and significantly decrease after successful DAAs in patients with low initial stages of liver fibrosis and normal body weight.
