AIM: Human leucocyte antigen (HLA) system plays an essential role in the human immune system activity and the expression of some specific HLA antigens could modify the immune response to vaccinations. Celiac disease is included among the diseases associated to specific HLA profiles, principally characterized by the expression of the HLA DQ2 antigen.
METHODS:Our study was a retrospective study, leaded on a group of celiac children, with the object to evaluate their immunological response to both obligatory and recommended vaccinations in childhood. It was a retrospective study, including 66 patients affected by celiac disease, between 3 and 15 years of age, and a control group of 50 children of the same age. All patients performed both obligatory and recommended vaccinations as indicated in the Italian standard regimen for vaccinations. The immunologic response to each vaccine was analysed and compared in the two groups. Moreover, authors also studied the immunologic response to vaccines in celiac children comparing patients whose diagnosis was made before 18 months of age with those whose disease was diagnosed after 18 months of age.
RESULTS: Our results showed that in celiac patients the immunological response to vaccine is similar to that one found in general population, except for HBV vaccine.
CONCLUSION: The evaluation of immunological response to HBV vaccine should be regularly effectuated in celiac children and revaccination should be recommended.
