Is this high prevalence due to a greater susceptibility to HPV infection, which is known to be frequent in its latent form in women? Objective: This study aims to identify HPV genotypes in HIV+ and HIV−women to understand HPV molecular epidemiology in Senegal. Material and Method: Endocervical samples from 331 HIV+ and HIV−women, sexually active, were collected. The molecular identification of the 28 genotypes studied (19 HPV-HR and 9 HPV-LR) was carried out after DNA extraction, by multiplex PCR with the Anyplex™II HPV28 detection kit from Seegene on CFX96™Bio-Rad machine. The comparisons were made by calculating the p-value and odds ratio with R Studio software (version 4.1.0). The results were considered significant if p Results: The general prevalence of HPV was significantly higher in HIV+ women with 78.95% vs 64.65% for HPV;72.18% vs 57.07% for HPV-HR;57.14% vs 34.34% for HPV-BR (p −women. Conclusion: Our results showed that the prevalence of HPV, HPV-HR and HPV-BR was significantly higher in HIV+ women. Non-vaccine genotypes were among the most found genotypes. Groups of HIV+ women aged between 35 and 50, married and using contraception were significantly more infected with HPV than the same groups of HIV-women.展开更多
A total of 531 sexually active female populations from Manipur (north-eastern India), was chosen for this study.

Out of 531 females from Manipur, 111 (20.9%) were HIV positive and 420 were HIV negative (79%). PCR amplification of the MY region of the HPV L1 gene using consensus MY09/11 primer showed 3.7% positivity in Manipur. Interestingly HPV infection among the HIV infected population from Manipur was found to be higher (9%) compared to the non HIV infected population from Manipur (3.7%). Further, single PCR for detecting the 16/18 genotypes and multiplex PCR for the other high risk groups showed equal prevalence of 16 and 18 and other high risk groups (1.3% each) in Manipur. This result was further confirmed by the sequencing and phylogenetic analysis. Thus, our study showed fairly high HPV prevalence rate among the HIV infected population compared to the non HIV cases in Manipur and also equal prevalence of 16/18 genotypes with other high risk groups. According to our knowledge this is the first kind of a genotypic study among the HPV-HIV co-infected population from northeastern states of India.展开更多
