Abstract Background: It has been demonstrated in immunocompromised females that HR HPV genotypes other than 16 and 18 have been detected in a significant proportion of these individuals. We aim to evaluate the frequency of HR HPV genotypes in a population of HIV-positive Caribbean women, detect characteristics associated with HR HPV infections other than HPV16 and 18, and investigate the clustering of HPV genotypes in this population. Methods: One hundred and seventy-six non-pregnant, HIV-positive females ≥18 years were recruited. Each participant received a vaginal examination and completed a questionnaire. Results: Mean age was 38.7 years for women positive for HR HPV and 44.4 years for women negative for HR HPV (P value = 0.0018). The majority of the HR HPV-positive women were on HAART for 2-4 years. Non-negative matrix factorization identified HPV 16, 18, 52 and 58 as the most influential HPV high-risk types. Among the women who were HIV+ for more than 2 years, secondary CART analysis revealed those aged ≤29 had statistically significant different cervical abnormality profile compared to women >29 years; specifically, younger women were more likely to have dysplasia, while older women had normal cervical cytology. Also, the mean number of years on HAART for ≤29 years old was only 1 year (std dev. ±1.3) while those >29 years old the mean was 3.6 years (std. dev. ± 2.5) (p = 0.009). Conclusions: HR HPV in the immunocompromised female consists of more than just HPV 16 and 18, but also types HPV 52 and 58, which are likely to influence the course of HPV infections and the development of cervical cytological abnormalities. Targeted interventions to boost treatment compliance among HIV- positive women are needed to reduce the risk of cervical abnormalities. Citation Format: Elizabeth Blackman, Dionne N.
