ABSTRACT
Background: Hepatitis C virus (HCV) has been related to inflammatory myopathies
and serum markers of autoimmunity.
Clinical cases:The cases of three patients with positive to HCV by ELISA are described.
One woman and two men with mean age of 55 years (limits: 35-68). They
were referred to our hospital because of muscle weakness, myalgia and skin lesions in
one case. The woman had a history of blood transfusion before 1990 and the men used
illegal drugs. Serum muscle enzymes, including creatine kinase, aldolase, LDH, AST, and
ALT, were markedly elevated. Inflammation in the muscle tissue was demonstrated by
biopsy specimens of these patients. Two ended up with kidney damage and underwent
peritoneal dialysis. Patients received prednisone without antivirals for their short stay
and elevated muscle enzymes were decreased. Two of them died.
Conclusions: HCV might be one of the possible etiological factors responsible for
inflammatory myopathy, although relation cause and effect have yet to be demonstrated.
