Abstract

Immune responses to specific antigens can be influenced by an individual’s genetic make-up. We examined whether the efficacy of a vaginal mucosal vaccine for urinary tract infections (UTI) was affected by a patient’s human leucocyte antigen (HLA) phenotype. Urinary tract infection data and the HLA phenotypes of 47 women participating in a phase II clinical trial of immunization for recurrent UTI were statistically analysed for associations between HLA-A, -B, -DR, or -DQ phenotype and postimmunization infection course. Women who received the vaccine and had HLA-DR phenotypes other than DR2 had significantly delayed times to re-infection compared with women receiving placebo. Vaccine-treated patients with the HLA-DR2 phenotype had re-infection courses that were not different than women receiving placebo. These results indicate that the efficacy of a vaginal mucosal UTI vaccine may be influenced by an individual’s HLA-DR phenotype.
