Molecular epidemiology of human papillomavirus genotypes in oral rinses from HIV‐positive and HIV‐negative Jamaican patients

Abstract

Aim Human papillomavirus (HPV) has been reported to be associated with oral and oropharyngeal cancer. However, little information is available about the epidemiology of oral HPV infection in Jamaica. The purpose of the present study was to assess the prevalence of oral HPV strains using the oral rinse method in HIV and non‐HIV Jamaican patients, as well as to determine the association of HPV with sexual practices, smoking, and alcohol use. Methods A cross‐sectional study was conducted on patients attending The University of the West Indies Mona Dental Polyclinic and the Centre for HIV/AIDS Research and Education Services. Salivary samples were tested through molecular analysis for 37 HPV genotypes using the linear array HPV genotyping test. A survey questionnaire was used to obtain demographic details, smoking history, alcohol practice, sexual practice, and history of HPV testing. Results The HPV prevalence was 8.65% in 18‐64 y olds (N = 104), with a slight female predilection (55%). No high‐risk HPV types were found. HPV‐84 was the most common type in both HIV and non‐HIV patients; 66.7% of HPV‐positive participants reported that they had six or more lifetime sexual partners. Conclusion The prevalence of oral HPV was similar to that in other countries. No statistically‐significant relationship was observed between the prevalence of HPV and either the number of sexual partners, smoking, or alcohol history. A nationwide study on oral HPV detection might be helpful in developing a HPV vaccination policy in Jamaica.
