Absence of hepatitis C virus in British patients with type 1 autoimmune chronic active hepatitis--a polymerase chain...

Despite several studies from continental Europe reporting a high prevalence of antibodies to the hepatitis C virus (HCV), there has been little evidence of such infection in patients from the United Kingdom. The use of the polymerase chain reaction combined with two separate second generation anti-HCV assays is reported here in 58 UK patients with well-documented autoimmune chronic active hepatitis. All patients were in corticosteroid induced remission. All sera were collected prospectively for the specific purpose of this study. HCV-RNA was not detected by use of the polymerase chain reaction in any of the patients and antibodies to HCV were only detected in one patient. No evidence was found for the involvement of the hepatitis C virus in UK patients with classical, corticosteroid sensitive autoimmune chronic active hepatitis.
