Overview

Prevention of infectious hepatitis type A and B in patients with autoimmune hepatitis is important with regardto possible course deterioration of the basic disease after a history of infectious hepatitis. The most effectivepossibility is immunisation with a combined vaccine against both types of viral hepatitis. The objective of thepresented study implemented in 2000 - 2001 was to assess the safety and immunogenicity of vaccination incl. theinfluence on the clinical course of autoimmune hepatitis in patients vaccinated with the combined vaccine Twinrix.In the immunogenicity no significant difference was recorded in the post-vaccination titres of anti-HAV antibodiesbetween the patients and healthy subjects in similar clinical studies. Child patients (6 subjects,mean age 12.8 years)as well as patients older than 16 years (4 subjects, mean age 19.8 years) achieved significantly lower anti-HBsantibody values than their healthy peers. In all investigated patients a 100% anti-HAV seroconversion was foundone month after the completed basic immunization with 3 doses of vaccine (pattern: month 0, 1, 6). Two patients(age 19 and 21 years) did not respond to the antigen of the hepatitis B virus in the vaccine and were described asnon-responders. Anti-HBs seroprotection was only 50% in group older than 16 years.Vaccination did not influencein a significant way the clinical course of the disease and the vaccine was well tolerated.
