A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem

Genetic factors are implicated in the response of normal subjects to hepatitis B vaccine. The aim of our study was to investigate if HLA Class I and II proteins could participate in a nonresponse to this vaccine in immunocompromised, namely hemodialyzed, patients. One hundred and seven hemodialyzed patients (68 men and 39 women, mean age 35 years) were vaccinated with Pasteur Hevac B vaccine, with a mean delay of 2 months following the onset of chronic hemodialysis. Patients were considered nonresponders when their serum antiHBs remained less than 10 mUI/ml on at least two occasions within the 12 months following the vaccination. HLA-A, B and DR antigens were determined by complement-dependent microlymphotoxicity. Ninety patients (84%) were responders and 17 (16%) nonresponders. The HLA-A1, B8 and DR3 frequency was higher in nonresponders (35, 35 and 44%, respectively) than in responders (18, 4 and 14%, respectively). The extended haplotype HLA-A1, B8, DR3 was more frequent in the former (19%) than in the latter (2%) (p less than 0.03). There was only one female within the nonresponders (6%) as compared to 37 (41%) in the responders (p less than 0.05). We conclude that genetic determinants (sex and HLA markers) play a critical role in the induction of an antiHBs immune response in both immunoincompetent hemodialyzed patients and normal immunocompetent hosts.
