Chronic viral diseases of the liver are frequently characterized by clinical signs of intrahepatic complications. Infection caused by the hepatitis C virus should be considered as a systemic disorder associated with the frequent development of various extrahepatic complications, such as cryoglobulinemia, glomerulopathy, lymphoproliferative diseases, seronegative arthritis, type 2 diabetes mellitus, lichen planus, and late cutaneous porphyria. Often, extrahepatic complications become the main

In some cases, the treatment of extrahepatic manifestations becomes an independent, complex task, surpassing the actual treatment of chronic hepatitis C. The relationship between hepatic and extrahepatic complications of viral hepatitis C is not linear; rather, extrahepatic manifestations often outstrip the development of liver damage. The effects of hepatitis C virus on the organs and systems of the body are caused by the direct action of the virus, pathogenetically induced by the development of steatosis/steatohepatitis, and by the disruption of system regulation of hepatokines and cytokines. Treatment of chronic hepatitis C virus infection should be comprehensive and should include antiviral therapy, treatment of metabolic-associated fatty liver disease and treatment of hepatic-related disorders. Antiviral therapy with preparations of direct antiviral action allows the prevention of not only liver complications but also of many extrahepatic complications of hepatitis C virus. Comorbid states significantly increase the natural progression of chronic hepatitis C infection and vice versa: the hepatitis C virus increases the clinical manifestations of co-pathology. In the age of direct antiviral drugs, it is possible to eliminate the hepatitis C virus, but in some cases, elimination alone does not arrest the progression of liver disease.
