Abstract
ObjectiveTo determine the presence of human papillomavirus (HPV) in the oral mucosa of blood donors (BD) and risk factors associated with HPV and oral cancer. Materials and methodsProspective cross-sectional study, population matched to BD from the National Cancer Institute, Mexico for HPV identification in oral cytological samples using the CLART® Human Papillomavirus 2 Kit (35 genotypes) and risk factors. ResultsOf 352 BD with signed informed consent, 285 were selected by simple randomization. The prevalence of oral HPV was 17.5% (95% CI 13–21.9%), the genotype was identified in 13 cases, with a total of 16 genotypes (10 high-risk), the most common being 16 and 84. Five cases had multiple infections, three with at least one high-risk type. Associations were found for marital status (OR 3.3) and educational level (OR-1.9). ConclusionsThe percentage of HPV-positive cases in blood donors with no risk practices was similar to that found in Spanish-speaking population studies in which at least one risk practice was described. The presence of other genotypes with high oncogenic risk and multitype infection, described as a marker of persistence of HPV infection, is highlighted.
