Celiac.com 06/07/2013 - A number of studies have indicated that people with celiac disease have an inadequate response to hepatitis B vaccination. In an effort to better understand the issue, a team of researchers recently set out to assess hepatitis B vaccination response in relation to gluten exposure status in patients with celiac disease.
The research team included F. Zingone, P. Capone, R. Tortora, A. Rispo, F. Morisco, N. Caporaso, N. Imperatore, G. De Stefano, P. Iovino, and C. Ciacci. They are affiliated with the Department of Medicine and Surgery at the University of Salerno in Salerno, Italy.
To measure the gluten exposure status at the time of vaccination, they compare three groups of patients, along with a control group. In all, the study included 163 celiac patients.
- Group A contained 57 patients exposed to gluten, including patients vaccinated as 12-year-old adolescents, for whom celiac disease diagnosis was established after vaccination.
- Group B contained 46 patients not exposed to gluten, including patients vaccinated as 12-year-old adolescents and on a gluten-free diet at the time of vaccination.
- Group C was composed of 60 infants, including those vaccinated at birth.
- Group D included 48 healthy, vaccinated, non-celiac subjects.
The researchers then compared the response of celiac patients to hepatitis B vaccination with the response by healthy subjects. They found that 43.9% of patients in group A, 34.8% of patients in group B, 58.3% of patients in group C, and 8.3% of patients in group D showed inadequate response to hepatitis B immunization.
Overall, group A versus group D, P less than 0.001; group B versus group D, P = 0.002; group C versus group D, P = 0.001, while they found no significant difference for group A versus group B and group A versus group C.
This study suggests that gluten exposure does not influence the response to hepatitis B immunization, and that the human leukocyte antigen likely plays the main immunological role in poor responses to hepatitis B-vaccinated celiac patients.
