title: [Reactivity to hepatitis B vaccination (HBV) in patients with uremia: association with defined HLA antigen configuration and complement protein allotypes C4A, C4B and B factor (Bf)].
abstract: Genes, which are responsible for the effectivity of immune response are located on the chromosome 6 similarly as the genes of the class I and II of the major histocompatibility complex (MHC) together with the genes of some complement proteins (C4A, C4B, B factor/Bf/). The study investigates the interdependence between HLA configuration as well as complement protein allotypes (C4A, C4B, Bf) with the reactivity to HBV vaccination of ESRD [end stage renal disease]-patients. 153 ESRD-patients (68 females, 85 males; mean duration of hemodialysis therapy 8.2 +/- 5.1 years) were studied. Subjects were vaccinated (Gen-H-B-Vax-D; Merck, Sharp and Dohme, 40 micrograms/dosis i.m.) in the schedule at 0, 1, 2, and 6 month. Non-responders (NR) were defined when the anti-HBs antibody titer was below 10 U/liter. HLA typing was performed by means of microlymphocytotoxicity assay, whereas complement allotypes were estimated by using high voltage gel electrophoresis with subsequent specific immunofixation with antibodies against C4A, C4B and Bf. In the non-responders group [NR = 34] a) the significantly higher occurrence of single HLA-A1 and/or HLA-B8 and/or Cw4 or DR3 or DR7 or DQ2 have been found. In about 40% of NR HLA-A1, -B8, -DR3, or -DQ2 antigens occurred as homozygotes.
