HCV-associated mixed cryoglobulinemia and b-cell non-Hodgkin's lymphoma - pathogenetically related problems.

Hepatitis C virus (HCV) is a global population problem due to its high prevalence, usually late diagnosis, the difficulties of treatment. In the prognosis of patients with HCV not only hepatic, but increasingly frequent of extrahepatic HCV manifestations, such as mixed cryoglobulinemia (CG), are important. Mixed CG is currently considered as a B-cell benign lymphoproliferative disorders. The role of HCV virus in the pathogenesis of lymphoproliferative diseases is confirmed by a large number of epidemiological studies, as well as by the effectiveness of antiviral therapy in patients with non-Hodgkin's lymphoma (NHL). The purpose of the review was to provide an overview of recent literature data and the meta-analysis of epidemiological data explaining the role of HCV in the development of NHL. The review also discusses the treatment for HCV-associated NHL by antiviral therapy or other therapeutic options, such as chemotherapy.
