  • Title: Association of symptomatic acute human parvovirus B19 infection with human leukocyte antigen class I and II alleles.
    Author: Kerr JR, Mattey DL, Thomson W, Poulton KV, Ollier WE.
    Journal: J Infect Dis; 2002 Aug 15; 186(4):447-52. PubMed ID: 12195370.
    Abstract:
    To determine the effect of the major histocompatibility complex on the development of symptoms during acute human parvovirus B19 infection, we compared human leukocyte antigen (HLA) class I and II alleles in 36 patients with symptomatic acute B19 infection with those in >900 control subjects from northwestern England. The frequency of each of HLA-DRB1*01 (P=.016), DRB1*04 (P=.007), and DRB1*07 (P<.0001) alleles was significantly higher in parvovirus B19 patients than in control subjects. In the parvovirus group, 63.9% carried the rheumatoid arthritis-associated shared epitope sequence, compared with 45% of control subjects (odds ratio [OR], 2.2; 95% confidence interval [CI], 0.97-4.8; P=.04), and carriage was associated with fatigue during the acute phase (OR, 4.2; 95% CI, 0.8-23.9; P=.047). All symptomatic parvovirus-associated HLA-DRB1 molecules carry a neutrally charged glutamine at position 10 and a positively charged lysine at position 12 of the first hypervariable region. HLA-B49 was associated with parvovirus infection independently of HLA-DRB1*01, DRB1*04, and DRB1*07.
