Oral sex practices, oral human papillomavirus and correlations between oral and cervical human papillomavirus prevalence among female sex workers in Lima, Peru

Few data exist on oral human papillomavirus (HPV) prevalence in female sex workers (FSWs). Information regarding oral sex practices of 185 Peruvian FSWs, 18-26 years of age, was obtained via survey and compared with HPV testing results of oral rinse samples. Oral HPV prevalence was 14/185 (7.6%); four (28.9%) HPV genotypes were carcinogenic. One hundred and eighty-two participants reported having had oral sex; 95% reported condom use during oral sex with clients and 9.5% with partners. Women who had oral sex more than three times with their partners in the past month were more likely to have oral HPV than women who had oral sex three times or less (P = 0.06). Ten (71.4%) women with oral HPV were HPV-positive at the cervix; conversely 8.3% of women with cervical HPV were HPV-positive in the oral cavity. The prevalence of oral HPV was relatively low, considering the high rates of oral sex practiced by these women.

Female sex workers (FSWs) have a notably high risk of acquiring human papillomavirus (HPV) infections. Relatively few studies address the type-specific prevalence and incidence of HPV among FSWs in sub-Saharan Africa. FSWs (n = 348) attending the Korogocho clinic in Nairobi, Kenya participated from August 2009 to March 2011. HPV DNA was detected using the SPF10-LiPA25 PCR assay. Baseline prevalence of HPV infection and cervical dysplasia were calculated, stratified by HIV-serostatus. Incidence rate (IR) of infection was calculated as number of new infections from baseline over person-months among 160 HPV-negative participants with complete 12-month follow-up. Baseline HPV prevalence was 23.6% for any HPV and 20.4% for high-risk HPV (hrHPV) types. Most prevalent types were HPV52 (10.1%), HPV35 (2.3%), and HPV51 (2.3%). A quarter (24%) of participants were HIV-positive. HPV prevalence was higher in HIV-positive (32.1%) than HIV-negative (20.8%) participants. hrHPV prevalence was higher in HIV-positive (27.4%) than HIV-negative (18.2%) women. During follow-up, HPV IR was 31.4 (95% CI: 23.8–41.5) for any HPV and 24.2 (95% CI: 17.9–32.8) for hrHPV types. HPV52 had the highest IR (6.0; 95% CI: 6.5–10.3). Overall HPV and hrHPV prevalence were lower than expected, but both prevalence and incidence were higher in HIV-positive than in HIV-negative women.

The Difference

The prevalence of high-risk human papillomavirus (HR-HPV) has been reported to be three times higher in female sex workers (FSWs) in Callao, Peru than in the general population of women in Peru. Prevalence of HR-HPV among male clients has not yet been reported. A total of 150 men soliciting intercourse in sex work venues submitted questionnaires, samples for sexually transmitted infection (STI) testing, and self-collected penile samples prior to and following intercourse for HPV genotyping. We identified variables associated with pre-coital HR-HPV, and compared HR-HPV detection pre- and post-coitus. Prior to intercourse, HR-HPV prevalence was 41.9%. Married clients were less likely than unmarried clients to have HR-HPV detected ( p = 0.03). While post-coital HR-HPV prevalence was higher (47.6%), the difference was not statistically significant. However, there was a significant increase in the mean number of HR-HPV DNA strains detected before (0.75) and after (0.94) intercourse ( p = 0.02). No cases of gonorrhoea or syphilis and six (4.1%) cases of chlamydial infection were detected. Despite low prevalence of other STIs, male clients had a high HR-HPV prevalence. The increase in detection of HR-HPV following intercourse demonstrates a potential for transmission of HR-HPV despite high self-reported condom use.

BACKGROUND Asymptomatic Trichomonas vaginalis (TV) and human papillomavirus (HPV) co-infection is perceived to have a devastating combined effect on victims. Hence, we investigated TV/ HPV co-infection and determined the risk factors associated with it in female sex workers (FSW). METHODS A cross-sectional study was used to recruit 338 subjects from 6 local government areas (LGAs) in Nigeria for 18 months. Agglutination tests for blood samples, and direct and wet examination of urine and vaginal swabs were conducted in the laboratory. Life style of FSWs was surveyed; data were analyzed with Chi-Square test (X2), paired and unpaired t-test and logistic regression analysis with statistical significance set at p< 0.05. RESULTS Life style characteristics were significantly associated with HPV and TV co-infection (p < 0.001). The model explained 49.9% (Nagelkerke R2) of the variance in infections among FSWs and effectively classified 93.2% of cases. Those involved in oral sex were 1.795 times more likely to be infected compared to those not involved (OR: 1.795; 95% C.I.: 1.005 – 33.525; p=0.001). Street and residential FSWs all have increased likelihood of being infected. Hard drug usage was also associated with an increased likelihood of being infected with the disease (OR: 3.582; 95% C.I.: 1.573 - 11.756; p=0.001). CONCLUSIONS Life style (hard drug usage and oral sex practices) was observed in association with HPV/ TV co-infection in FSWs with a preponderance of 49.9%. This study demonstrated the value of screening for genital infections in HPV positive subjects in order to reduce the probable synergistic effects of co-infections.

Sex Practices

Background Previous studies have described inconsistent condom use in Chinese- and Thai-speaking female sex workers in Sydney, Australia. In the present study, we describe the demographics and safe sexual practices in the Chinese- and Thai-speaking female sex workers attending the Sydney Sexual Health Centre (SSHC) in 2014–15. Methods: A self-completed 60-item anonymous questionnaire, adapted from previous surveys conducted in 1993 and 2003, was translated into Chinese and Thai and administered to female sex workers attending the SSHC or seen on outreach. Results: In all, 488 surveys were distributed, of which 435 were returned; 43% in Chinese and 57% in Thai. Most women did not plan on sex work before their arrival in Australia. Compared with Chinese-speaking women, Thai-speaking women rated themselves higher on English language literacy, had better knowledge of the transmission of HIV and sexually transmissible infections (STIs) and were more likely to practice 100% condom use. Overall, 72% of the sex workers surveyed reported consistent condom use for vaginal sex at work. Conclusions: Consistent condom use for vaginal sex at work among Chinese- and Thai-speaking female sex workers has decreased slightly from that reported in a similar survey conducted by the SSHC in 2003, when 85% of sex workers reported consistent condom use. There are significant differences between Chinese- and Thai-speaking sex workers in terms of both knowledge and safer sex practices. Ongoing health promotion efforts should focus on providing culturally appropriate education around STIs and safe sex practices not only to workers, but also to parlour owners, managers and consumers.

Cervical cancer is a largely preventable disease mediated by persistent infection with high-risk Human Papillomaviruses (Hr-HPV). There are now three approved vaccines against the most common HPV genotypes. In Ghana, mortality due to cervical cancer is on the rise, due to the absence of an organized and effective cervical cancer prevention and control program. Data on circulating HPV genotypes is important for studying the likely impact of mass introduction of HPV vaccination of the female population before sexual debut. High HPV prevalence has been reported in Female Sex Workers (FSWs), who constitute an important active group for maintenance of HPV in the population. This study was conducted to determine the size of HPV prevalence in this group and to provide information for future assessment of the impact of vaccine introduction in the country. We conducted a cross-sectional study where the snowballing technique was used to identify and select FSW’s ≥18 years, operating within suburbs of Greater Accra Region (GAR). A risk factor assessment interview was conducted and cervical swabs were collected for HPV-DNA detection and genotyping by Nested Multiplex PCR. Hundred participants, age ranging from 18 to 45 years, median 24 years, were studied. The prevalence of Cervical HPV was 26%. Eleven genotypes were detected comprising 9 high-risk in order of decreasing prevalence HPV-16 (8%), HPV-35 (5%), HPV-33/39/-68 (3%), HPV-52/51/59 (2%) and HPV-18 (1%) and 2 Low-risk types, HPV-42(3%), and HPV-43 (1%). Three women had HPV types that could not be genotyped by our method. Oral contraceptives use was associated with a reduced chance of HPV infection (P=0.002; OR=0.19, 95% CI 0.07-0.54). This study found a high HPV prevalence among FSWs in the GAR. A high number of Hr-HPV genotypes seen are vaccine preventable, providing additional compelling argument for implementing a national cervical cancer prevention plan including vaccination.
