[Hepatitis C virus infection and hepatocarcinogenesis].

Hepatitis C virus infection causes approximately 4 million new infections worldwide, and 399 000 deaths due to its complications, cirrhosis and hepatocellular carcinoma (HCC). Microenvironmental changes, chronic inflammation, oxidative stress, endoplasmic reticulum stress caused by HCV infection, genetic and epigenetic changes can result in primary liver cancer during decades. The direct oncogenic property of HCV is wellknown.

[The role of gut microbiota in chronic liver diseases, and treatment possibilities].

The community of microorganisms in the intestine, namely gut microbiome lives in symbiosis with the host, contributing to its homeostasis and influencing it simultaneously. It can be suspected that gut microbiome plays a central role in the pathophysiology of intestinal and extraintestinal diseases: determining their development, progress and complications. Recently, intestinal microbiome has become a highlighted field of interest and important topic in research, especially in hepatology.
