Objectives. To investigate associations between HLA-DRB1 and HLA-DQB1 polymorphisms with low- and high-grade cervical lesions in Argentine population and the role human papillomavirus status in these associations.
Materials and Methods. Cervical biopsies and peripheral blood samples were taken from 32 patients with cervical intraepithelial neoplasia grade 1 (CIN 1) and 44 patients with cervical CIN 3 or invasive squamous cell carcinomas. Cervical cells and peripheral blood samples from 40 healthy women were included as control group. Human papillomavirus detection and typing were done by polymerase chain reaction (PCR) MY09, 11-restriction fragment length polymorphisms, or PCR 5+, 6+ dot-blot hybridization, and HLA DR/DQ typing by the PCR-sequence-specific oligonucleotide probes method.
Results. HLA-DRB1*04 and HLA-DQB1*0302 were found to be positive associated with the CIN 3/invasive squamous cell carcinomas subgroup, whereas HLA-DRB1*13 and HLA-DQB1*02 were negatively associated with the same group, when comparing to the control group.
Conclusions. The data support the hypothesis that HLA-DRB1*04 and HLA-DQB1*0302 may be considered risk factors for malignant progression, whereas HLA-DRB1*13 and HLA-DQB1*02 may have a protective role. Further studies with a larger group are needed to confirm these susceptibility and protective roles in disease progression in Argentine population.
