The objective is to assess the efficacy of Hepatitis B Virus vaccination in a population of IBD patients treated with immunosuppressive medications.
Inflammatory Bowel Disease
Biological: ENGERIX-B (HBV Vaccine)
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
||Assessment of Hepatitis B Vaccination Efficacy in Patients With Inflammatory Bowel Diseases
Primary Outcome Measures:
- protective level of anti HBs antibodies [ Time Frame: 1 month after the last does of vaccine ] [ Designated as safety issue: No ]
Antibody titer >10 IU/ml 30 days following last vaccine dose will be considered protective.
In the work done by Altunoz et al., titer rate below 10 IU was observed in 40% of the patients, while 40% of the patients achieved a rate of above 100 IU. Therefore, we can estimate that the geometric mean of distribution is approx. 50 IU. A sample size of 37 patients in each group achieves a power of 80% to detect a ratio above 1.37 between the two vaccinated groups.
