[Update in Hepatitis C virus associated extrahepatic manifestations].
BACKGROUND
Since the discovery of the hepatitis C virus, many manifestations, so called extra-hepatic manifestations (EHM), are largely reported with more or less relationship proofs.
This article proposes a review of the main extra-hepatic manifestations associated with the Hepatis C Virus infection and which remain a topical subject, more than fifteen years after the discovery of this virus. Mixed cryoglobulin and its vasculitic manifestations are still one of the more frequent Hepatis C Virus associated-extra-hepatic manifestations. Its management may be critically changed due to the increasing use of anti-CD20 therapy. Among other HCV-EHM, the following extra-hepatic manifestations are still of interest: the chronic fatigue syndrome, the sicca syndrome, the non-insulin-dependent diabetes mellitus, malignant B cell proliferations, mainly the Hepatis C Virus-related splenic lymphoma with villous lymphocytes and the production of auto-antibodies.


CONCLUSIONS
The mechanisms underlying these HCV-associated EHM are ill-elucidated and still remain of great interest as proved by current studies. The use of anti-CD20 antibodies in the treatment of cryoglobulinemic vasculitis is also under investigation.
