Vasculitis and cryoglobulinemia associated with persisting cholestatic hepatitis A virus infection.

Abstract

Extrahepatic manifestations are rarely found in hepatitis A viral (HAV) infection. Only a single case of HAV infection associated with cutaneous vasculitis and cryoglobulinemia has been reported. Described here is a patient with a persisting cholestatic type of HAV infection who developed cutaneous vasculitis and cryoglobulinemia during the third month of her illness. Analysis of the cryoglobulins revealed IgM anti-HAV antibodies.
