Human leukocyte antigen (HLA) phenotype DQ2 is considered the most important genetic marker for un-responsiveness to hepatitis B vaccine. Since celiac disease (CD) is also strongly associated with the same haplo-type it may be hypothesized that celiac patients are less able to respond to the vaccine. We report a retrospective study on celiac patients vaccinated with three doses of 10 mu g at 3, 5 and 11 months of age by an intramuscular injection of a recombinant hepatitis B vaccine (Engerix B). We found 30 of 60 celiac patients (50%) unresponsive to vaccination and a significant higher number of responders among patients younger than 18 months at the time of celiac disease diagnosis. Our study confirms that celiac patients have a lower percentage of response to hepatitis B vaccination than healthy subjects. These findings provide useful information to evaluate if current vaccine strategies should be reassessed and if revaccination should be recommended. (C) 2009 Elsevier Ltd. All rights reserved.
