68Hepatitis A vaccine is the most frequently used traveller's vaccine, yet data on its ability to induce protective immunity in immunosuppressed travellers are scarce. The investigators assess the hepatitis A virus (HAV) antibody response in patients with rheumatoid arthritis (RA) treated with Tumor Necrosis Factor (TNF) - inhibitors and/or methotrexate (Mtx).
Methods: Parameters registered at baseline were: age, sex, duration of disease, medications, activity of disease (Visual Analogue Scale=VAS, Health Assessment Questionnaire Disability Index = HAQ, Disease Activity Score =DAS-28, CRP and total IgG in plasma). Hepatitis A vaccine (Epaxal or Havrix) were given at 0 and 6 months. Hepatitis A virus (HAV) antibodies is measured before vaccination and at month 1, 6 (before dose 2), 7 and 12 with quantitative HAV IgG, using the HAVAb-IgG Architect System, and by the HAVAB 2.0 assay on the AxSYM machine from Abbott. The level of protective immunity to HAV is defined as HAV IgG > 10mIU/mL.
1.0 ml im ( Havrix) and 0.5 ml im (Epaxal. Both vaccines are given two times with 6 months interval
Inclusion Criteria: Diagnosis of rheumatoid arthritis TNF-alfa blocker and / or methotraxate in use as a medication against RA A desire to get protected against hepatitis A Men and women age 18-65 years Written informed consent Women of childbearing potential must use effective contraception - Exclusion Criteria: Treatment with rituximab within 9 months before study start Known previous hepatitis A infection Previous vaccination against hepatitis A Allergy to eggs or formaldehyde Pregnancy or lactation Excessive use of alcohol Mental retardation Acute disease at the time of examination (fever > 38 degrees) Volunteer works as an employee of the researchers Previous vaccination against hepatitis A Egg-, henprotein- or formaldehyde allergy Pregnancy or lactation Excessive use of alcohol Another vaccine given within a month Acute disease at the time of examination (fever > 38 degrees) Not suitable for other reason in the investigator's opinion (other serious disease, i.e. AIDS/HIV-positive, cancer with ongoing cytostatic treatment)
