The currently used quadrivalent vaccine may be insufficient to give satisfactory HPV coverage in Rwanda. HPV Screening may be effective to identify women at risk of developing cervical cancer, particularly if provided to high-risk patients.
Objectives
In this study, we determined the incidence and persistence of human papillomavirus (HPV) strains and of squamous intraepithelial lesions (SIL) or worse cytology in 237 HIV‐positive and HIV‐negative Rwandan women and whether the interleukin (IL)‐28B single nucleotide polymorphism (SNP) at rs12979860 correlated with susceptibility to and persistence of HPV infection.
Methods
Cervical samples were collected at baseline and after 9, 18 and 24 months for a 40‐HPV DNA screening test and a ThinPrep Pap test. Genotyping of the IL‐28B SNP rs12979860 was performed using real‐time polymerase chain reaction (PCR).
Results
Chronic high‐risk (HR) HPV infections occurred in 56% of HIV‐positive women, while no HIV‐negative women developed HPV chronicity. High‐grade SIL (HSIL) or cancer was diagnosed in 38% of HIV‐positive women with persistent HR‐HPV infections. HIV and HR‐HPV positivity at baseline were factors associated with an increased risk of HPV persistence. Additionally, HR‐HPV positivity at baseline was associated with an increased risk of developing HSIL or worse cytology. The unfavourable T/x genotype at rs12979860 is common among Africans, and women with this genotype were found to be more commonly infected with HPV.
Conclusions
HPV screening in Rwanda may help to identify women at risk of developing cervical cancer and polymorphism in IL‐28B may be associated with risk of contracting HPV infection.
Here we wanted to assess whether sexual risk behaviour differs dependent by human immunodeficiency virus (HIV) status by following 100 HIV− and 137 HIV+ women recruited at two university teaching hospitals in Rwanda. Women were tested for sexually transmitted infections (STIs; trichomoniasis, syphilis, hepatitis B and C) and for reproductive tract infections (RTIs; candidiasis, bacterial vaginosis (BV)) and were interviewed at baseline and 9 months later. BV was the most prevalent infection, while syphilis was the most common STI with a 9-month incidence of 10.9% in HIV+ women. Only 24.5% of women positive for any RTI/STI contacted their health facility and got treatment. More HIV− women than HIV+ women had had more than one sexual partner and never used condoms during the follow-up period. The use of condoms was affected neither by marital status nor by concomitant STIs besides HIV. Our data highlight the importance of public education regarding condom use to protect against STIs in an era when HIV no longer is a death sentence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
