Purpose
Hepatitis 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).

Response to Hepatitis A Vaccine |
Biological: hepatitis A vaccine ( HAVRIX or EPAXAL) |

| Study Type: | Interventional |
| Study Design: | Intervention Model: Single Group Assignment Masking: Open Label Primary Purpose: Prevention |
| Official Title: | Hepatitis A Vaccination in Patients With Rheumatoid Arthritis Treated With TNF-inhibitors and/or Methotrexate |
- seroconversion after a single dose of hepatitis A vaccine [ Time Frame: one month after dose ] [ Designated as safety issue: No ]ELISA-titers are determined before first dose and at 1 and 6 months later
- seroconversion rates after a second dose of hepatitis A vaccine [ Time Frame: 12 monrths ] [ Designated as safety issue: No ]We determine seroconversion rates before the second vaccine dose ( 6 months after the first) and at 1 and 6 months after the second dose

Biological: hepatitis A vaccine ( HAVRIX or EPAXAL)
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.
