Consequences of extrahepatic manifestations of hepatitis C viral infection (HCV)
Journal Title: Advances in Hygiene and Experimental Medicine - Year 2016, Vol 70, Issue
Abstract
The hepatitis C virus (HCV) is a primarily hepatotropic virus. However, numerous extrahepatic symptoms are observed in patients chronically infected with HCV, e.g. cryoglobulinemia, lymphoproliferative disorders, kidney diseases, disturbances of the central and peripheral nervous system, thyroid gland, pancreas, lymph nodes and pituitary gland, that develop at various times after the infection. Complex mechanisms underlie these processes, both molecular, related to direct effects of the virus on cells or tissues and indirect mechanisms, resulting from the response of the immune system to infection (via cytokines or oxidative stress), and from the antiviral treatment used. Understanding these mechanisms may contribute to the definition of new prognostic factors, important for the early diagnosis of the infection, which in turn may improve treatment efficacy.This paper is a review of the incidence of selected extrahepatic manifestations of HCV infection and their underlying pathogenetic mechanisms and risk factors.
