Polymorphisms of the Human Leukocyte Antigen DRB1 and DQB1 Genes and the Natural History of Human Papillomavirus Infection
Copyright policy )Polymorphisms of the Human Leukocyte Antigen DRB1 and DQB1 Genes and the Natural History of Human Papillomavirus Infection
This study investigated, through cohort analysis, whether HLA-DRB1 and -DQB1 variability is related to human papillomavirus (HPV) infection prevalence and persistence. HLA-DRB1 and -DQB1 genes were typed in 620 samples from the Ludwig-McGill cohort. HPV positivity was tested in specimens collected every 4 months during the first year of follow-up. Persistent and long-term infections were defined as at least 2 or 3 consecutive positive results for the same HPV type, respectively. The magnitudes of associations were estimated by unconditional logistic regression analysis adjusted for potential confounders. The DRB1*0301-DQB1*0201 haplotype was associated with a 2-fold reduction in risk for transient and persistent HPV infections. DRB1*1102-DQB1*0301 showed a lower-risk effect only for persistence. DRB1*1601-DQB1*0502 and DRB1*0807-DQB1*0402 were associated with a 7-fold and a 3-fold increase, respectively, in risk for persistence. The results suggest that HLA class II polymorphisms are involved in clearance and maintenance of HPV infection.
