The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified June 2012 by Soroka University Medical Center.

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)
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 ]
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.
