About this trial

This is an interventional treatment trial for Celiac Disease focused on measuring celiac disease, hepatitis B vaccine

Eligibility Criteria

1 Year - undefined (Child, Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patients above 1 year of age with confirmed diagnosis of celiac disease by characteristic symptoms, serology and small bowel biopsy.
  • Completion of the IM HBV vaccine series in infancy.
  • HBsAb titer of ≤10mIU/mL at the time of enrollment.

Exclusion Criteria:

  • Immunocompromised subjects or those receiving medications that may modulate or suppress the immune system (i.e. azathiopurine, 6-MP, steroids).
  • Inability to obtain written informed consent and patients' assent, as appropriate by the maturity age.

Arm Description

celiac patients who did not respond to initial hepatitis B vaccine series , will receive repeat hep B vaccine via intramuscular route

celiac patients who did not respond to initial hepatitis B vaccine series , will receive repeat hep B vaccine via intradermal route

Outcomes

Primary Outcome Measures

1. The primary endpoint of the study will be comparison of the geometric mean titers of anti-HBs between the intradermal and the intramuscular groups.

Secondary Outcome Measures

1. Rate of responders four weeks after the completion of the series 2. Rate and characteristics of adverse drug reactions 3. Numerical increase in the antibodies titer before and after vaccination 4. Rate of responders in the cross over phase

5. Study Description

Brief Summary
Celiac disease and infection with hepatitis B virus (HBV) are very prevalent worldwide and carry a high morbidity rate. It has been recently shown that patients with celiac disease very often fail to develop immunity after standard vaccination for HBV during infancy. In this study, we will evaluate whether a second vaccination series via a different route of administration (into the skin rather than the muscle) results in a better immunological response in celiac patients. Eligible patients will be randomized to receive a 3-dose vaccination series into the skin or to the muscle. Rate of responders and level of immunity will be compared. This study will facilitate better protection of celiac patients to this potentially deadly virus.
