Background: Chlamydia trachomatis(CT) and Neisseria gonorrhoeae (NG) are the most common bacterial sexually transmitted infections (STIs) worldwide. In the absence of affordable point-of-care STI tests, WHO recommends STI testing based on risk factors. This study aimed to develop a prediction tool with a sensitivity of >90% and efficiency (defined as the percentage of individuals that are eligible for diagnostic testing) of

Background Female genital schistosomiasis (FGS) occurs when Schistosoma haematobium eggs are deposited in reproductive tissue. Female genital schistosomiasis in the cervical mucosa is associated with increased vascularity. If FGS is associated with the presence of hemoglobin in cervicovaginal lavage (CVL), the use of urinary reagent strips to detect hemoglobin in CVL could supplement FGS diagnosis. Methods Nonmenstruating, nonpregnant, sexually active women aged 18–31 participating in the HPTN 071 (PopART) Population-Cohort were invited in 2 Zambian communities. Genital self-swabs and a urine specimen were collected at a home visit, and CVL and hand-held colposcopy were performed at a midwife led clinic visit. Urinary reagent strips were used to identify hemoglobin in CVL. Eggs and circulating anodic antigen (CAA) were detected from urine. Visual-FGS was defined as the presence of sandy patches, rubbery papules, or abnormal blood vessels. Polymerase chain reaction (PCR)-FGS was defined as Schistosoma deoxyribonucleic acid detected by real-time PCR on CVL or cervical or vaginal swab. Results Of 209 women with home genital swabs and companion CVL specimens, 66% (138 of 209) had detectable CVL hemoglobin, 13.4% (28 of 209) had PCR-defined FGS, and 17.2% (36 of 209) had visual-FGS. Active Schistosoma infection, diagnosed by CAA or urine microscopy, was present in 21.0% (44 of 209) participants. Active Schistosoma infection (P = .4), PCR-FGS (P = 0.7), and visual-FGS (P = 0.3) were not associated with CVL hemoglobin presence. Results did not differ in subgroups with high infection burden (cycle threshold < 35 or 2–3 positive genital PCR). Conclusions Polymerase chain reaction-FGS, visual-FGS, and active Schistosoma infection were not associated with the presence of CVL hemoglobin. Further research is needed to establish accessible community-based FGS diagnostics.

Indigenous adolescents and young people in Panama are at high-risk for sexually transmitted infections, due in part to limited access to condoms and comprehensive sexual and reproductive health (SRH) education. There is a paucity of evidence on how to develop sexual and reproductive health education programmes that incorporate different sources of learning. We used Bronfenbrenner’s Ecological Theory to understand two key sources of learning: noncaregivers (school or healthcare personnel) and caregivers (parents/grandparents/stepparents). Better understanding about sexual and reproductive health learning sources could provide a foundation for the development of targeted, culturally congruent interventions. This study included ethnographic observation in two Indigenous communities in Panama, followed by semi-structured interviews with young people and caregivers. Findings suggest non-caregiver sexual and reproductive health education was commonly provided by teachers, and increasingly through the Internet. Caregivers focused on topics of abstinence/delaying sexual debut, pregnancy, and STIs/HIV; condoms pregnancy, and STIs/HIV. Condoms and condom use were not mentioned. Traditional sexual and reproductive health teaching by same-gender caregivers took place through the rituals of mokän (girls at menarche) and grön (boys 13–14 years). To develop culturally congruent interventions, wesuggest programmes to improve sexual and reproductive health knowledge and access to condoms, which respect and build on social and traditional learning spaces.

Background Youth are a high-risk group for sexually transmitted infections (STIs). To increase access to STI testing, convenient approaches for sampling and testing are needed. We assessed the acceptability of self-collected vaginal swabs (SCVS) for STI testing among young women (16–24 years) attending a community-based sexual and reproductive health service in Zimbabwe. Methods A SCVS was used for point-of-care testing for Trichomonas vaginalis and a urine sample for testing for Chlamydia trachomatis and Neisseria gonorrhoeae. A questionnaire was administered to investigate the acceptability of SCVS versus self-collected urine samples. In-depth interviews (IDIs) explored the experience of SCVS and reasons for sample collection preference. Qualitative analysis was predominantly deductive. Results We recruited 129 women who took up STI testing (median age 20 years, IQR 18–22 years) and conducted 12 IDIs. Most participants reported that they understood the instructions (93.0%) and found SCVS easy (90.7%). Many participants felt relaxed (93.0%), in control (88.4%) and that they had enough privacy (90.7%). Pain or discomfort were reported by 16.3% and embarrassment by 15.5%. Among the 92 (71.3%) participants who provided both a SCVS and urine sample, 60.9% preferred SCVS. Sample collection method preferences were similar between 16–19 and 20–24year-olds. In IDIs, clear instructions, privacy, trust in the service and same-day results were perceived as important facilitators to taking up SCVS. Participants frequently described feeling relaxed and confident whilst taking a SCVS. Pain and discomfort were uncommon experiences. Conclusions SCVS for STI testing are acceptable to young women and a feasible method of sample collection in community-based settings.

Background Human papillomavirus (HPV) associated cancers are increasingly reported globally, including in sub-Saharan Africa (SSA). However, with the exception of cervical HPV infection, data from SSA on the epidemiology of oral and genital HPV infections are limited. This study assessed the prevalence and concordance of oro-genital and anal HPV genotype specific infections among women in the general population. Methods We conducted a cross-sectional study in sexually active women aged 18–45 years in Ibadan, Nigeria. After a face-to-face interview and clinical examination, oral, cervical, vulvar, and anal samples were collected from participants and tested by the Anyplex II 28 HPV assay. Descriptive and multivariable analyses were used to report prevalence and risk factors associated with HPV infections. Results The prevalence of any vulva, cervical, anal, and oral HPV infections was 68.0% (210/309), 59.7% (182/305), 56.8% (172/303), and 16.1% (14/286), respectively. There was an inverse relationship between age-group and HPV prevalence of HPV in all anatomic sites except for the oral HPV infections. HPV 35 was the most prevalent high-risk HPV genotype in the vulva, cervix and oral cavity. Associated risk factors for HPV infection in each of the anatomic sites were reported. Overall, 10.0% (31/310) women had concordance of any HPV type in the four anatomic sites. Conclusion There was a high prevalence of oro-genital and anal HPV infections among sexually active Nigerian women, with concordance of HPV types in the cervix, vulva, anus and oral cavity. We advocate large longitudinal studies that will involve sampling of multiple anatomic sites and inclusion of other women in the community for better understanding of HPV epidemiology in this region.

Background The cervicovaginal microbiota, including sexually transmitted infections (STIs), have not been well described in female genital schistosomiasis (FGS). Methods Women (aged 18–31, sexually active, nonpregnant) were invited to participate at the final follow-up of the HPTN 071 (PopART) Population Cohort in January–August 2018. We measured key species of the cervicovaginal microbiota (Lactobacillus crispatus, L. iners, Gardnerella vaginalis, Atopobium vaginae, and Candida) and STIs (Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and Mycoplasma genitalium) using quantitative PCR (qPCR). We evaluated associations of the microbiota and STI presence and concentration with FGS (qPCR-detected Schistosoma DNA in any of 3 genital specimens). Results The presence and concentration of key cervicovaginal species did not differ between participants with (n = 30) or without FGS (n = 158). A higher proportion of participants with FGS had T. vaginalis compared with FGS-negative women (P = .08), with further analysis showing that T. vaginalis was more prevalent among women with ≥2 Schistosoma qPCR-positive genital specimens (50.0%, 8/16) than among FGS-negative women (21.5%, 34/158; P = .01). Conclusions We found weak evidence of an association between the presence of T. vaginalis and FGS, with a stronger association in women with a higher-burden FGS infection. Additional research is needed on potential between-parasite interactions, especially regarding HIV-1 vulnerability.

Background Female genital schistosomiasis (FGS) has been associated with prevalent HIV-1. We estimated the incidence of HIV-1 infection in Zambian women with and without FGS. Methods Women (aged 18–31, nonpregnant, sexually active) were invited to participate in this study in January–August 2018 at the final follow-up of the HPTN 071 (PopART) Population Cohort. HIV-1-negative participants at enrollment (n = 492) were included in this analysis, with testing to confirm incident HIV-1 performed in HPTN 071 (PopART). The association of incident HIV-1 infection with FGS (Schistosoma DNA detected by polymerase chain reaction [PCR] in any genital specimen) was assessed with exact Poisson regression. Results Incident HIV-1 infections were observed in 4.1% (20/492) of participants. Women with FGS were twice as likely to seroconvert as women without FGS but with no statistical evidence for a difference (adjusted rate ratio, 2.16; 95% CI, 0.21–12.30; P = .33). Exploratory analysis suggested an association with HIV-1 acquisition among women with ≥2 positive genital PCR specimens (rate ratio, 6.02; 95% CI, 0.58–34.96; P = .13). Conclusions Despite higher HIV seroconversion rates in women with FGS, there was no statistical evidence of association, possibly due to low power. Further longitudinal studies should investigate this association in a setting with higher schistosomiasis endemicity.

ObjectivesCervical cancer is the leading cause of cancer-related mortality among women in sub-Saharan Africa (SSA). Data on human papillomavirus (HPV) epidemiology in adolescent girls in SSA are essential to inform HPV vaccine policy recommendations for cervical cancer prevention. We assessed the burden of HPV infection, and risk factors for infection, among adolescent girls around the time of sexual debut.MethodsCross-sectional study of secondary school girls aged 17–18 years in Tanzania. Consenting participants provided samples for HPV and STI testing. Vaginal swabs were tested for 37 HPV genotypes by Roche Linear Array. Logistic regression was used to identify factors associated with HPV infection. Y chromosome was tested as a marker of recent condomless sex.Results163/385 girls (42.3%) reported previous penetrative sex. HPV was detected in 125/385 (32.5%) girls, including 84/163 (51.5%) girls reporting previous sex and 41/222 (18.5%) reporting no previous sex. High-risk (HR) genotypes were detected in 70/125 (56.0%) girls with HPV infection. The most common HR genotype was HPV-16 (15/385; 3.9%). The prevalence of other HR HPV vaccine genotypes was between 0.8% and 3.1%. Among 186 girls who reported no previous sex, were negative for Y chromosome, and had no STI, 32 (17%) had detectable HPV. Lactobacillus sp and bacterial vaginosis-associated bacteria were negatively and positively associated, respectively, with HPV.ConclusionsHPV prevalence among adolescent girls around the time of sexual debut was high. However, prevalence of most vaccine genotypes was low, indicating that extending the age range of HPV vaccination in this region may be cost-effective.

Background Oral and anal sexual behaviours are increasingly reported among adolescents and adults reporting heterosexual sex in peer-reviewed journals in high income countries, but less is known about these behaviours in low and middle-income countries, especially in sub-Saharan Africa. The aim of this systematic review is to describe the prevalence of, and motivations for, oral and anal sex among adolescents and adults reporting heterosexual sex in sub-Saharan Africa. Methods A systematic review of published articles that reported oral and or anal sex in sub-Saharan Africa was conducted from seven databases up to and including 30th August 2018. Results Of 13,592 articles, 103 met the inclusion criteria. The prevalence of reporting ever practising oral sex among adolescents, university students and a combined population of adolescents/adults ranged from 1.7–26.6%, 5.0–46.4% and 3.0–47.2% respectively. Similarly, prevalences of reported ever practising anal sex ranged from 6.4–12.4% among adolescents, 0.3–46.5% among university students and 4.3–37.8% amongst combined population of adolescents and adults. Higher prevalences of oral and anal sex were reported among populations at high-risk for sexually transmitted infections and HIV and university students and, in most studies, both behaviours were more commonly reported by males than females. Heterosexual oral and anal sexual acts were associated with some high-risk behaviours such as inconsistent condom use and multiple sexual partners. Conclusion Reported oral and anal sex between men and women are prevalent behaviours in sub-Saharan Africa. Health professionals and policy makers should be aware of these behaviours and their potential associated health risks.

Increased rates of Zika virus have been identified in economically deprived areas in Brazil at the population level, yet, the implications of the interaction between socioeconomic position and prenatal Zika virus exposure on adverse neurodevelopmental outcomes remains insufficiently evaluated at the individual level. Using data collected between September 2015 and September 2019 from 163 children with qRT-PCR and/or IgM-confirmed prenatal exposure to Zika virus participating in a prospective cohort study in Rio de Janeiro, Brazil (NCT03255369), this study evaluated the relationships of socioeconomic indicators with microcephaly at birth and Bayley-III neurodevelopmental scores during the early life course. Adjusted logistic regression models indicated increased odds of microcephaly in children born to families with lower household income (OR, 95% CI: 3.85, 1.43 to 10.37) and higher household crowding (OR, 95% CI: 1.83, 1.16 to 2.91), while maternal secondary and higher education appeared to have a protective effect for microcephaly compared to primary education (OR, 95% CI: 0.33, 0.11 to 0.98 and 0.10, 0.03 to 0.36, respectively). Consistent with these findings, adjusted linear regression models indicated lower composite language (&minus, 10.78, 95% CI: &minus, 19.87 to &minus, 1.69), motor (&minus, 10.45, 95% CI: &minus, 19.22 to &minus, 1.69), and cognitive (&minus, 17.20, 95% CI: &minus, 26.13 to &minus, 8.28) scores in children whose families participated in the Bolsa Fam&iacute, lia social protection programme. As such, the results from this investigation further emphasise the detrimental effects of childhood disadvantage on human health and development by providing novel evidence on the link between individual level socioeconomic indicators and microcephaly and delayed early life neurodevelopment following prenatal Zika virus exposure.

Although heterosexual oral and anal sexual behaviors have been reported in sub-Saharan Africa, little is known about how they are understood and perceived, particularly, in West Africa. We undertook a qualitative exploration of local terminologies and sexual scripts associated with heterosexual oral and anal sex in preparation for a quantitative survey. We held focus group discussions (18) and interviews (44) with younger and middle-aged men and women from the general population and female sex workers (FSWs) in selected communities in Ibadan. Most participants had heard of oral and anal sex. Younger adults aged 18-25 years, particularly male participants and FSWs, appeared more informed than older adults in the general population. Sexually explicit movies were the most cited source of information. Oral and anal sexual behaviors were considered sensitive, with different local names, meanings, and interpretations. Participants advised against the use of slang terms in research. We identified six different scripts employed by participants in discussing oral and anal sex practices: protecting sexual relationship, financial reward, an alternative to vaginal sex, pleasure, male dominance and control, and risk, stigma, and disgust.

Background Menstrual health and hygiene (MHH) is a human rights issue; yet, it remains a challenge for many, especially in low- and middle-income countries (LMICs). MHH includes the socio-political, psychosocial, and environmental factors that impact women’s menstrual experiences. High proportions of girls and women in LMICs have inadequate MHH due to limited access to menstrual knowledge, products, and stigma reinforcing harmful myths and taboos. The aim of this pilot was to inform the design of an MHH sub-study and the implementation and scale-up of an MHH intervention incorporated into a community-based cluster-randomized trial of integrated sexual and reproductive health (SRH) services for youth in Zimbabwe. The objectives were to investigate (1) uptake of a novel MHH intervention, (2) menstrual product preference, and (3) the factors that informed uptake and product choice among young women. Methods Female participants aged 16–24 years old attending the community-based SRH services between April and July 2019 were offered the MHH intervention, which included either a menstrual cup or reusable pads, analgesia, and MHH education. Descriptive statistics were used to quantitatively assess uptake and product choice. Focus group discussions and in-depth interviews with participants and the intervention team were used to investigate the factors that influenced uptake and product choice. Results Of the 1732 eligible participants, 1414 (81.6%) took up the MHH intervention at first visit. Uptake differed by age group with 84.6% of younger women (16–19 years old) compared to 79.0% of older women (20–24 years old) taking up the intervention. There was higher uptake of reusable pads (88.0%) than menstrual cups (12.0%). Qualitative data highlighted that internal factors, such as intervention delivery, influenced uptake. Participants noted the importance of access to free menstrual products, analgesics, and MHH education in a youth-friendly environment. External factors such as sociocultural factors informed product choice. Barriers to cup uptake included fears that the cup would compromise young women’s virginity. Conclusions Pilot findings were used to improve the MHH intervention design and implementation as follows: (1) cup ambassadors to improve cup promotion, sensitization, and uptake; (2) use of smaller softer cups; and (3) education for community members including caregivers and partners.

Summary Background The prevalence of sexually transmitted infections (STIs) among youth is high in sub-Saharan Africa. We investigated the uptake of testing for and prevalence of Chlamydia trachomatis (chlamydia) and Neisseria gonorrhoeae (gonorrhoea) infections among youth in community-based settings in Zimbabwe, and explored the facilitators and barriers to testing. Methods This study was nested within a cluster randomised trial of community-based delivery of integrated HIV and sexual and reproductive health services for youth aged 16–24 years. Chlamydia and gonorrhoea testing via urine samples using the Xpert CT/NG test was offered in the four intervention clusters in Harare, Zimbabwe. Factors associated with testing uptake were investigated in a subset of participants (n=257) using hierarchical multivariate logistic regression. In-depth interviews with a separate purposively selected sample (n=26) explored facilitators and barriers to STI testing and partner notification and were analysed using thematic analysis. Findings Between June 1, 2019, and Jan 31, 2020, there were 6200 attendances by 4440 participants (78·2% women, 21·8% men) median age 20·3 (IQR 17·9–22·8) years. 1478 participants had 1501 tests done, and 248 tests were positive and 1253 tests were negative for chlamydia or gonorrhoea, or both. STI test uptake was 33·3% (95% CI 31·9–34·7), increasing from 11·7% in June, 2019, to 37·1% in January, 2020. The prevalence of chlamydia or gonorrhoea, or both, was 16·5% (95% CI 14·7–18·5; 248 of 1501), with only seven participants (3%) showing symptoms. The overall yield of testing was 4·0% (95% CI 3·5–4·5; 248 of 6200). Uptake was associated with having symptoms (adjusted odds ratio [OR] 14·8, 95% CI 1·66–132·07) and negatively associated with being single (adjusted OR 0·33, 95% CI 0·13–0·84) or having a boyfriend or girlfriend (adjusted OR 0·19, 95% CI 0·087–0·43) compared with being married, and being a student compared with being employed (adjusted OR 0·26, 95% CI 0·10–0·68). Perceived risk and symptoms of STIs were motivators for testing whereas misinformation, anticipated stigma, and concern about confidentiality were barriers. Interpretation The prevalence of chlamydia or gonorrhoea, or both, was high among youth but only a minority were symptomatic. Therefore most infections would remain untreated without access to STI testing. Provision of education, counselling, and confidentiality are essential to improve uptake and acceptability of STI testing. Funding Wellcome Trust.

Background Qualitative data show negative impacts of menstruation on health and education in many settings, but there are few longitudinal quantitative studies of the impact of menstruation. We analyse associations with menstrual anxiety and school attendance in a study of Ugandan secondary school students. Methods Data were from a longitudinal pilot study of a menstrual health intervention (MENISCUS), conducted in two secondary schools in Entebbe sub-district, Uganda. Self-completed menstrual-related data, including menstrual anxiety, were collected from 232 participants pre- and post-intervention. A sub-cohort of 100 randomly-selected post-menarcheal girls were asked to self-complete daily diaries during 10 months of follow-up, with data on menstrual flow, pain, and school attendance. We used multivariable logistic regression to estimate associations with menstrual anxiety among all girls at baseline, and random-effects logistic regression to estimate associations of menstrual characteristics with school non-attendance for 3 months pre-intervention in the sub-cohort, adjusting for within-girl clustering. Results Overall, 130/222 (58.6%) of menstruating girls reported being anxious about their next period. Menstrual anxiety was higher in those not living with their mother (adjusted odds ratio (OR) = 1.91; 95% confidence interval (CI) 1.01–3.60), believing menstrual myths (aOR = 1.83; 0.95–3.50 for not agreeing that it is healthy for a girl to run, dance or cycle during her period; aOR = 1.97; 1.04–3.73 for agreeing that when a girl has her period she is unclean), lower menstrual confidence (aOR = 2.49; 1.33–4.65 for avoiding physical activity during her period; aOR = 1.68; 0.89–3.17 for not feeling comfortable to talk to other girls about her period; aOR = 2.89; 1.28–6.54 for agreeing that boys/girls tease them about their periods; and aOR = 2.27; 1.21–4.27 for worrying about being teased during her period). Those with lower knowledge about menstruation were less likely to report anxiety (aOR = 0.44; 0.23–0.84). During the pre-intervention period of the sub-cohort, school non-attendance was associated with menstrual pain, with 21.7% of girls missing school on days when they reported pain vs. 8.3% on days when no pain was reported (aOR = 3.82; 1.66–8.77). Conclusions Menstruation causes substantial anxiety in Ugandan schoolgirls, and menstrual pain is associated with missing school on period-days. Menstrual health interventions should address socio-cultural aspects of menstruation to reduce anxiety, and provide education on pain management strategies to support school attendance.

Background Poor menstrual health and hygiene (MHH) is a globally recognised public health challenge. A pilot study of an MHH intervention was conducted in two secondary schools in Entebbe, Uganda, over 9 months. The intervention included five components delivered by the implementing partner (WoMena Uganda) and the research team: (i) training teachers to implement government guidelines for puberty education, (ii) a drama skit to reduce stigma about menstruation, (iii) training in use of a menstrual kit (including re-usable pads), (iv) guidance on pain relief methods including provision of analgesics and (v) improvements to school water, sanitation and hygiene (WASH) facilities. The aim of the process evaluation was to examine implementation, context and possible causal pathways. Methods We collected information on fidelity, dose, reach, acceptability, context and mechanisms of impact using (i) quantitative survey data collected from female and male students in year 2 of secondary school (ages 13–21; 450 at the baseline and 369 at endline); (ii) qualitative data from 40 in-depth interviews with parents, teachers and female students, and four focus group discussions with students, stratified by gender; (iii) data from unannounced visits checking on WASH facilities throughout the study; and (iv) routine data collected as part of the implementation. Quantitative data were used primarily to assess fidelity, dose and reach. Qualitative data were used primarily to assess acceptability, context and possible mechanisms. Results Both schools received all intervention elements that were delivered by the research team and implementing partner. The drama skit, menstrual kit and pain management intervention components were delivered with fidelity. Intervention components that relied on school ownership (puberty education training and WASH improvements) were not fully delivered. Overall, the intervention was acceptable to participants. Multilevel contextual factors including schools’ social and physical environment, and family, cultural and social factors influenced the acceptability of the intervention in the school setting. The intervention components reinforced one another, as suggested in our theoretical framework. Conclusion The intervention was feasible to deliver and acceptable to the schools and students. We propose a full-scale cluster-randomised trial to evaluate the intervention, adding a school-based MHH leadership group to address issues with school ownership. Trial registration ClinicalTrials.gov NCT04064736. Registered August 22, 2019, retrospectively registered.

ObjectivesAchieving good menstrual health and hygiene (MHH) is a public health challenge and there is little evidence to inform interventions. The aim of this study was to pilot test an intervention to improve MHH and school attendance in Uganda, in preparation for a future cluster-randomised trial.DesignLongitudinal study with pre–post evaluation of a pilot intervention.SettingTwo secondary schools in Entebbe, Uganda.ParticipantsOf the 473 eligible students in secondary 2 (S2) at baseline, 450 (95.1%; 232 girls and 218 boys) consented/assented. 369 students (188 girls; 81.0%; and 181 boys; 83.0%) participated in the endline survey.InterventionThe intervention comprised training teachers to improve delivery of government guidelines for puberty education, training in use of a menstrual kit and pain management, a drama skit, provision of analgesics and improvements to school water and sanitation hygiene facilities.Primary and secondary outcome measuresFeasibility and acceptability of delivering the intervention. Baseline and endline quantitative surveys were conducted, with qualitative interviews conducted at endline. School attendance was assessed using self-completed daily diaries among a nested cohort of 100 female students.ResultsThere were high levels of uptake of the individual and behavioural intervention components (puberty education, drama skit, menstrual hygiene management (MHM) kit and pain management). The proportion of girls reporting anxiety about next period decreased from 58.6% to 34.4%, and reported use of effective pain management increased from 76.4% to 91.4%. Most girls (81.4%) reported improved school toilet facilities, which improved their comfort managing menstruation. The diary data and qualitative data indicated a potential intervention impact on improving menstrual-related school absenteeism.ConclusionsThe pilot study showed that the multicomponent MHM intervention was acceptable and feasible to deliver, and potentially effective in improving menstruation knowledge and management. A cluster-randomised trial is needed to evaluate rigorously the intervention effects on MHM and school attendance.Trial registration numberNCT04064736; Pre-results.

BackgroundThere are limited data on the epidemiology of HPV in different anatomical sites of female sex workers (FSW). We investigated the prevalence and concordance of cervical, vulval, oral and anal HPV among FSW in Ibadan, Nigeria.MethodsFSWs aged 18–45 years were enrolled in a cross-sectional survey. After interview and clinical examination, samples were collected from mouth, cervix, vulva and anus. HPV genotyping was done with Anyplex II 28HPV assay. Multivariable analyses were performed to explore associated risk factors and concordance of HPV infections across sites.ResultsIn total, 315 FSWs participated in the study with a mean age of 30–6.5 years. The prevalence of any HPV infection was 88% in the vulva, 84% in the cervix, 75% in the anus and 24% in the oral cavity. HPV 35 was the most prevalent and concordant high-risk type in the four sites. The risk factors for HPV infection by anatomic site varied.ConclusionThis large study showed a high prevalence and concordance of HPV infections of cervical, vulval, oral and anal HPV among FSWs in Nigeria. The potential to acquire and transmit HPV is high in this population, and we highlighted the urgency to protect young women through HPV vaccination.

Adequate menstrual hygiene management (MHM) requires access to water and sanitation and can be challenging for many women and girls living in resource-poor settings. Inadequate MHM has been associated with urogenital infections. The aim of this study is to assess the impact of a combined household-level piped water and sanitation intervention on MHM practices and urogenital infection symptoms (UGS) among women living in rural communities of Odisha (India). This study was nested within a pair-matched cohort study designed to assess impact of the Gram Vikas MANTRA program, which provided household-level piped water, bathing areas and latrine to all households in intervention villages, on diarrheal disease (primary outcome). The program did not specifically promote menstrual hygiene practices. Forty-five intervention villages were randomly selected from a list of those where implementation was previously completed at least five years before and matched to 45 control villages. Data for the main study was collected in four rounds from June 2015 to October 2016. For the MHM sub study, household surveys were administered in round four to randomly selected women aged 18 or older among study households from the 90 villages, to assess self-reported MHM practicesand urogenital infections symptoms. MHM practices were deemed adequate if they met some of the criteria developed on the basis of international monitoring that the GV program could modify (adequate frequency of absorbent change, washing the body with soap and privacy for managing menstruation). Multilevel mixed-effects logistic regression with a random effect distribution at the level of the pair and village was used to estimate the effect of the intervention on adequate MHM practices (primary outcome) and reported UGS (secondary outcome). A total of 1045 women (517 from intervention and 528 from control) were included in the study. Women who lived in the villages receiving the intervention, were more likely to report adequate MHM practices than those in control villages (Adjusted OR (AOR) 3.54, 95% Confidence Interval (CI): 1.86-6.78). 14.51% and 15.53% of women living in the control and intervention villages reported having at least one UGS. There was no evidence of an intervention effect on reported UGS (AOR = 0.97, 95%CI: 0.64-1.46). While household latrines or bathing areas with access to piped water improve the environment that enable MHM practices related to privacy, the provision of such facilities alone had only a moderate impact in adequate MHM and did not have an effect on self-reported UGS. More targeted inventions that include behavior change strategies and that address other barriers may be necessary to improve MHM practices.

ObjectivesBacterial vaginosis (BV) increases women’s susceptibility to sexually transmitted infections (STIs) and HIV and may partly explain the high incidence of STI/HIV among girls and young women in East and southern Africa. The objectives of this study were to investigate the association between BV and sexual debut, to investigate other potential risk factors of BV and to estimate associations between BV and STIs.MethodsSecondary school girls in Mwanza, aged 17 and 18 years, were invited to join a cross-sectional study. Consenting participants were interviewed and samples were obtained for STI and BV testing. Factors associated with prevalent BV were analysed using multivariable logistic regression. Y-chromosome was tested as a biomarker for unprotected penile-vaginal sex.ResultsOf the 386 girls who were enrolled, 163 (42%) reported having ever had penile-vaginal sex. Ninety-five (25%) girls had BV. The prevalence of BV was 33% and 19% among girls who reported or did not report having ever had penile-vaginal sex, respectively. BV was weakly associated with having ever had one sex partner (adjusted odds ratio (aOR) 1.59;95% CI 0.93 to 2.71) and strongly associated with two or more partners (aOR = 3.67; 95% CI 1.75 to 7.72), receptive oral sex (aOR 6.38; 95% CI 1.22 to 33.4) and having prevalent human papillomavirus infection (aOR = 1.73; 95% CI 1.02 to 2.95). Of the 223 girls who reported no penile-vaginal sex, 12 (5%) tested positive for an STI and 7 (3%) tested positive for Y-chromosome. Reclassifying these positive participants as having ever had sex did not change the key results.ConclusionsTanzanian girls attending school had a high prevalence of BV. Increasing number of sex partner was associated with BV; however, 19% of girls who reported no penile-vaginal sex had BV. This suggests that penile-vaginal sexual exposure may not be a prerequisite for BV. There was evidence of under-reporting of sexual debut.

Highlights • FGS is associated with prevalent HIV-1 infection. • Characteristic FGS lesions may allow HIV-1 access to sub-epithelial target cells • Cervical egg granulomas bring together the target cells needed for HIV-1 infection • S. haematobium has been associated with altered systemic/genital cytokine levels • HIV-1 RNA concentrations may be altered in HIV-1 and schistosomiasis coinfection, Female genital schistosomiasis (FGS) results from egg-deposition in the female reproductive tract primarily by the waterborne parasite Schistosoma (S.) haematobium, and less commonly by Schistosoma (S.) mansoni. FGS affects an estimated 20-56 million women worldwide, mostly in sub-Saharan Africa. There is cross-sectional evidence of increased HIV-1 prevalence in schistosomiasis-infected women, but a causal relationship between FGS and either HIV-1 acquisition or transmission has not been fully established. Beyond the pathognomonic breach in the cervicovaginal barrier caused by FGS, this narrative review explores potential mechanisms for a synergistic relationship between S. haematobium infection, FGS, and HIV-1 acquisition through vaginal inflammation and target cell recruitment., Graphical abstract Female Genital Schistosomiasis and HIV-1 acquisition may be associated through vaginal inflammation, barrier dysfunction, and target cell recruitment.

Background There is scant information on sexually transmitted infection (STI) prevalence and risk factors among Latin American indigenous populations. We investigated STI prevalence and risk factors among adolescents of the Comarca Ngabe-Bugle indigenous region of Panama. Methods A population-based cross-sectional study was conducted among school-going adolescents aged 14 to 19 years. Eligible consenting participants self-completed a questionnaire and provided blood and urine samples. Female participants provided additional self-administered genital swabs. Seroprevalences of human immunodeficiency virus (HIV), syphilis, hepatitis B (HBsAg, anti-HBc), and herpes simplex virus type 2 (HSV-2) were determined in all participants; genital Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) by PCR among participants who reported sexual experience or were seropositive for HIV/syphilis/HSV2/HBsAg; high-risk human papillomavirus (HPV) by qualitative DNA assay and bacterial vaginosis (BV) by Gram-stain among female participants. Risk factors were identified by estimating adjusted odds ratios (AOR) using random-effects logistic regression. Results We enrolled 700 participants (median age, 17 years [female participants]; 18 years [male participants]) from 20 schools. Sexual experience was reported by 536 participants (76.6%). The HIV/STI prevalences among females and males were: HIV 0.4% and 1.0%, high-titer active syphilis 1.3% and 6.6%, HSV-2 16.1% and 16.1%, HBsAg 1.3% and 1.4%, anti-HBc 3.2% and 1.4%, NG 1.8% and 1.7%, CT 17.5% and 10.7%; among females: BV 42.9% and HPV 33.2%. CT was independently associated with being female (AOR, 2.02; 95% confidence interval [CI], 1.20-3.41); high-titer active syphilis with being male (AOR, 4.51; 95% CI, 1.17-17.40). Bacterial vaginosis was associated with sexual behavior (≥3 lifetime sex partners: AOR, 3.81; 95% CI, 1.29-11.26), HPV with sexual experience (AOR, 4.05; 95% CI, 1.62-10.09). Conclusions School-going indigenous adolescents in rural Panama have substantial STI burden. Targeted STI screening is required.

Women’s concerns about infertility and return to fertility after using hormonal contraceptives are well documented and are often dismissed as ‘myths’. Yet in settings with uncontrolled epidemics of sexually transmitted infections (STIs) among young people, using contraceptives to delay childbearing may coincide with being infected with an STI. Chlamydia in particular is an important cause of tubal factor infertility. The extent of STI prevalence has long been unmeasured in low-income and middle-income settings. Recent studies, however, have found a major uncontrolled chlamydia epidemic among young people in South Africa,1 2 suggesting that in other similar contexts there is also likely to be an unmeasured epidemic. This high prevalence of undiagnosed and untreated chlamydia is likely to be causing widespread fertility problems. Fears about future infertility are some of the most widely cited reasons for avoiding highly effective contraceptives, and are often characterised in the literature as ‘misconceptions’ or ‘myths’ because the methods themselves are unlikely to cause infertility directly.3 Infertility is devastating anywhere in the world and for many can cause economic deprivation and social isolation as well as personal grief. For example, while pregnancy can confer adult status on women,4 studies from Nigeria4 and Tanzania5 report women who had never given birth being characterised as ‘useless’. Infertile women in Ghana can face severe social stigma, marital strain and a range of mental health difficulties. …

Background Currently, bacterial 16S rRNA gene analyses are based on sequencing of individual variable regions of the 16S rRNA gene (Kozich, et al Appl Environ Microbiol 79:5112–5120, 2013).This short read approach can introduce biases. Thus, full-length bacterial 16S rRNA gene sequencing is needed to reduced biases. A new alternative for full-length bacterial 16S rRNA gene sequencing is offered by PacBio single molecule, real-time (SMRT) technology. The aim of our study was to validate PacBio P6 sequencing chemistry using three approaches: 1) sequencing the full-length bacterial 16S rRNA gene from a single bacterial species Staphylococcus aureus to analyze error modes and to optimize the bioinformatics pipeline; 2) sequencing the full-length bacterial 16S rRNA gene from a pool of 50 different bacterial colonies from human stool samples to compare with full-length bacterial 16S rRNA capillary sequence; and 3) sequencing the full-length bacterial 16S rRNA genes from 11 vaginal microbiome samples and compare with in silico selected bacterial 16S rRNA V1V2 gene region and with bacterial 16S rRNA V1V2 gene regions sequenced using the Illumina MiSeq. Results Our optimized bioinformatics pipeline for PacBio sequence analysis was able to achieve an error rate of 0.007% on the Staphylococcus aureus full-length 16S rRNA gene. Capillary sequencing of the full-length bacterial 16S rRNA gene from the pool of 50 colonies from stool identified 40 bacterial species of which up to 80% could be identified by PacBio full-length bacterial 16S rRNA gene sequencing. Analysis of the human vaginal microbiome using the bacterial 16S rRNA V1V2 gene region on MiSeq generated 129 operational taxonomic units (OTUs) from which 70 species could be identified. For the PacBio, 36,000 sequences from over 58,000 raw reads could be assigned to a barcode, and the in silico selected bacterial 16S rRNA V1V2 gene region generated 154 OTUs grouped into 63 species, of which 62% were shared with the MiSeq dataset. The PacBio full-length bacterial 16S rRNA gene datasets generated 261 OTUs, which were grouped into 52 species, of which 54% were shared with the MiSeq dataset. Alpha diversity index reported a higher diversity in the MiSeq dataset. Conclusion The PacBio sequencing error rate is now in the same range of the previously widely used Roche 454 sequencing platform and current MiSeq platform. Species-level microbiome analysis revealed some inconsistencies between the full-length bacterial 16S rRNA gene capillary sequencing and PacBio sequencing.

Background Fifteen longitudinal studies have shown associations between bacterial vaginosis and high risk human papillomavirus (hrHPV) acquisition and/or persistence, and/or cervical dysplasia. However, few studies assessed the vaginal microbiota (VMB) comprehensively, and none controlled the dysplasia association for persistent hrHPV. Methods 623 women attending HIV outpatient clinics in Johannesburg, South Africa, were examined for hrHPV (InnoLipA HPV Genotyping Extra Assay), cervical dysplasia (histology), and vaginal microbiota (VMB; V3-V4 Illumina HiSeq 2x300bp with Swarm OTU-picking) at baseline and endline, a median of 16 months after baseline. VMB research questions were addressed in two nested case-control designs. Results Hierarchical clustering resulted in seven VMB types: L. iners-dominated (Li; n=214 samples), Lactobacillus crispatus or L. jensenii-dominated (Lcj; n=68), Bifidobacterium-dominated (BD; n=2), lactobacilli + bacterial vaginosis (BV)-anaerobes (L+A; n=208), BV-like (BV; n=303); BV-anaerobe dominated (AD; n=56); and pathobiont-characterised (PB; n=19). Women with new or persistent hrHPV during follow-up were less likely to have an Lcj VMB type (compared to Li) at endline, and persistent hrHPV was associated with vaginal anaerobic dysbiosis at baseline (decreased lactobacilli, increased BV-anaerobes, and increased Nugent score). Women who developed CIN2+, compared to women with persistent hrHPV but no CIN2+, were more likely to have vaginal anaerobic dysbiosis at endline (decreased lactobacilli, increased BV-anaerobes, and increased diversity), but not at baseline. These associations persisted after controlling for age, hormonal contraception, and CD4+ count; several additional potential confounders (HIV plasma viral load, antiretroviral therapy, sexually transmitted infections, sexual risk-taking, among others) were evaluated. Conclusion Frequent hrHPV exposure (and/or increased sexual risk-taking) likely causes vaginal dysbiosis, but a bilateral relationship cannot be ruled out. Women with vaginal dysbiosis are not at increased risk of CIN2+ development when hrHPV status is taken into account, but vaginal dysbiosis does develop when CIN2+ lesions develop. These results should be confirmed in even larger longitudinal studies. Disclosure No significant relationships.

BACKGROUND: Few studies have evaluated the acceptability of self-collected vaginal swabs among young women in sub-Saharan Africa, including in school settings. We evaluated the acceptability of 2 conditions for the self-collection of swabs in secondary schools in Entebbe, Uganda. METHODS: Assenting girls with parental consent from 3 secondary schools were provided instructions for sampling, and randomly allocated to self-collection of vaginal swabs with or without nurse assistance to help with correct placement of the swab. Swabs were tested for bacterial vaginosis by Gram stain. Participants were followed up after 1 to 2 days and 1 to 2 weeks and invited for a qualitative interview. RESULTS: Overall 96 girls were enrolled (median age, 16 years; interquartile range, 15-17 years). At the first follow-up visit, participants in both arms reported that instructions for sample collection were easy to understand, and they felt comfortable with self-collection. Girls in the nurse assistance arm reported feeling less relaxed (27% vs. 50%, P = 0.02) than those in the arm without nurse assistance, but more confident that they collected the sample correctly (96% vs. 83%, P = 0.04). About half (47%) of participants agreed that self-sampling was painful, but almost all (94%) would participate in a similar study again. Qualitative data showed that participants preferred self-collection without nurse assistance to preserve privacy. Bacterial vaginosis prevalence was 14% (95% confidence interval, 8-22). CONCLUSIONS: In this setting, self-collection of vaginal swabs in secondary schools was acceptable and feasible, and girls preferred self-collection without nurse assistance. Self-collection of swabs is an important tool for the detection, treatment and control of reproductive tract infections in girls and young women.

Background Management of menstruation can present substantial challenges to girls in low-income settings. In preparation for a menstrual hygiene intervention to reduce school absenteeism in Uganda, this study aimed to investigate menstruation management practices, barriers and facilitators, and the influence of menstruation on school absenteeism among secondary school students in a peri-urban district of Uganda. Methods Qualitative and quantitative studies were conducted among consenting girls and boys aged 14–17 years in four secondary schools in Entebbe sub-District, Uganda. Methods included group and in-depth interviews with students, a quantitative cross-sectional questionnaire, a prospectively self-completed menstrual diary, key informant interviews with policy makers, and observations of school water, sanitation and hygiene facilities. Multiple logistic regression was used to assess factors associated with school absenteeism during the most recent menstrual period. Results Girls reported substantial embarrassment and fear of teasing related to menstruation in the qualitative interviews, and said that this, together with menstrual pain and lack of effective materials for menstrual hygiene management, led to school absenteeism. All policy makers interviewed reported poverty and menstruation as the key factors associated with school attendance. The 352 girls with questionnaire data had a median age of 16 (inter-quartile range (IQR) = 15,16) years, with median age at menarche of 13 (IQR = 13,14) years. Of these, 64 girls (18.7%) reported having stained their clothes and 69 (19.7%) reported missing at least 1 day of school, during their most recent period. Missing school during the most recent period was associated with physical symptoms (headache (odds ratio (OR) = 2.15, 95%CI:1.20, 3.86), stomach pain (OR = 1.89, 95%CI:0.89, 4.04), back pain (OR = 1.75, 95%CI:0.97, 3.14), and with changing protection 4 or more times per 24 h period (OR = 2.08, 95%CI:1.06, 4.10). In the diary sub-study among 40 girls, school absence was reported on 28% of period-days, compared with 7% of non-period days (adjusted odds ratio = 5.99, 95%CI:4.4, 8.2; p

Objectives Bacterial vaginosis (BV) is associated with increased risk for sexually transmitted infections (STIs) and HIV acquisition. This study describes the epidemiology of BV in a cohort of women at high risk for STI/HIV in Uganda over 2 years of follow-up between 2008–2011. Methods 1027 sex workers or bar workers were enrolled and asked to attend 3-monthly follow-up visits. Factors associated with prevalent BV were analysed using multivariate random-effects logistic regression. The effect of treatment on subsequent episodes of BV was evaluated with survival analysis. Results Prevalences of BV and HIV at enrolment were 56% (573/1027) and 37% (382/1027), respectively. Overall, 905 (88%) women tested positive for BV at least once in the study, over a median of four visits. Younger age, a higher number of previous sexual partners and current alcohol use were independently associated with prevalent BV. BV was associated with STIs, including HIV. Hormonal contraception and condom use were protective against BV. Among 853 treated BV cases, 72% tested positive again within 3 months. There was no difference in time to subsequent BV diagnosis between treated and untreated women. Conclusions BV was highly prevalent and persistent in this cohort despite treatment. More effective treatment strategies are urgently needed.

Background Sexually transmitted infections (STIs) and bacterial vaginosis (BV) are associated with increased transmission of HIV, and poor reproductive and sexual health. The burden of STIs/BV among young people is unknown in many high HIV prevalence settings. We conducted an acceptability, feasibility, and prevalence study of home-based sampling for STIs/BV among young men and women aged 15–24 years old in a health and demographic surveillance site (HDSS) in rural KwaZulu-Natal, South Africa. Methods and findings A total of 1,342 young people, stratified by age (15–19 and 20–24 years) and sex were selected from the HDSS sampling frame; 1,171/1,342 (87%) individuals had ≥1 attempted home visit between 4 October 2016 and 31 January 2017, of whom 790 (67%) were successfully contacted. Among the 645 who were contacted and eligible, 447 (69%) enrolled. Consenting/assenting participants were interviewed, and blood, self-collected urine (men), and vaginal swabs (women) were tested for herpes simplex virus type 2 (HSV-2), chlamydia, gonorrhoea, syphilis, trichomoniasis, and BV. Both men and women reported that sample collection was easy. Participants disagreed that sampling was painful; more than half of the participants disagreed that they felt anxious or embarrassed. The weighted prevalence of STIs/BV among men and women, respectively, was 5.3% and 11.2% for chlamydia, 1.5% and 1.8% for gonorrhoea, 0% and 0.4% for active syphilis, 0.6% and 4.6% for trichomoniasis, 16.8% and 28.7% for HSV-2, and 42.1% for BV (women only). Of the women with ≥1 curable STI, 75% reported no symptoms. Factors associated with STIs/BV included having older age, being female, and not being in school or working. Among those who participated in the 2016 HIV serosurvey, the prevalence of HIV was 5.6% among men and 19% among women. Feasibility was impacted by the short study duration and the difficulty finding men at home. Conclusions A high prevalence of STIs/BV was found in this rural setting with high HIV prevalence in South Africa. Most STIs and HIV infections were asymptomatic and would not have been identified or treated under national syndromic management guidelines. A nested STI/BV survey within a HDSS proved acceptable and feasible. This is a proof of concept for population-based STI surveillance in low- and middle-income countries that could be utilised in the evaluation of STI/HIV prevention and control programmes., Suzanna C Francis and colleagues report on acceptability, feasibility and prevalence results from home-based STI sampling among young men and women in rural KwaZulu-Natal, South Africa., Author summary Why was this study done? Adolescents and young adults are particularly vulnerable to sexually transmitted infections (STIs). The first strategic direction of the WHO Global Health Sector Strategy on Sexually Transmitted Infections 2016–2021 is to collect information on STI prevalence and incidence across representative populations. There is evidence that bacterial vaginosis (BV) is a risk factor for poor birth outcomes and STIs including HIV. The collection of BV prevalence may therefore also be important. Developing new cohorts for dedicated STI/BV prevalence studies may not be realistic, particularly in sub-Saharan Africa, where the impact of STIs/BV and their consequences may be greatest. Nesting STI/BV surveys within networks of health and demographic surveillance sites (HDSSs) would be an efficient way of providing data to better understand STI epidemiology among adolescents and young people in high HIV prevalence settings. What did the researchers do and find? We carried out a nested STI/BV survey among 1,342 adolescent and young people in an HDSS in KwaZulu-Natal, South Africa, between October 2016 and January 2017. Potential participants were contacted at home and invited to participate. Participants were interviewed, and samples were collected for STI/BV testing. We showed that this study was feasible within the 3.5-month time period: 1,171/1,342 (87%) individuals had ≥1 attempted home visit, of whom 790 (67%) were successfully contacted. The study was acceptable: among those contacted and eligible, 447/645 (69%) enrolled. Both men and women reported few problems with sample collection. We report a high burden of STIs/BV in this population, particularly of chlamydia (5% in men and 11% in women), herpes simplex virus type 2 (17% in men and 29% in women), and BV (42% in women). What do these findings mean? Nested STI/BV surveys in HDSSs can be feasible and acceptable; however, more survey time is needed to ensure that all potential participants are visited and contacted. These studies should be carried out in conjunction with studies to measure STI/BV prevalence in high-risk populations (e.g., female sex workers) to provide robust prevalence estimates. These data are essential to advocate, fund, plan, implement, and evaluate interventions for STI prevention and control among adolescents and young people. Strategies for the prevention and control of chlamydia, herpes simplex virus type 2, and BV are needed in this population.

WHO estimated that nearly 1 million people become infected every day with any of four curable sexually transmitted infections (STIs): chlamydia, gonorrhoea, syphilis, and trichomoniasis. Despite their high global incidence, STIs remain a neglected area of research. In this Commission, we have prioritised five areas that represent particular challenges in STI treatment and control. Chlamydia remains the most commonly diagnosed bacterial STI in high-income countries despite widespread testing recommendations, sensitive and specific non-invasive testing techniques, and cheap effective therapy. We discuss the challenges for chlamydia control and evidence to support a shift from the current focus on infection-based screening to improved management of diagnosed cases and of chlamydial morbidity, such as pelvic inflammatory disease. The emergence and spread of antimicrobial resistance in Neisseria gonorrhoeae is globally recognised. We review current and potential future control and treatment strategies, with a focus on novel antimicrobials. Bacterial vaginosis is the most common vaginal disorder in women, but current treatments are associated with frequent recurrence. Recurrence after treatment might relate to evidence that suggests sexual transmission is integral to the pathogenesis of bacterial vaginosis, which has substantial implications for the development of effective management approaches. STIs disproportionately affect low-income and middle-income countries. We review strategies for case management, focusing on point-of-care tests that hold considerable potential for improving STI control. Lastly, STIs in men who have sex with men have increased since the late 1990s. We discuss the contribution of new biomedical HIV prevention strategies and risk compensation. Overall, this Commission aims to enhance the understanding of some of the key challenges facing the field of STIs, and outlines new approaches to improve the clinical management of STIs and public health.

BACKGROUND: Uganda has long been successful in controlling the HIV epidemic; however there is evidence that HIV prevalence and incidence are increasing again. Data on the HIV/STI epidemic among sex workers are so far lacking from Uganda. This paper describes the baseline epidemiology of HIV/STI in a newly established cohort of women involved in high-risk sexual behavior in Kampala Uganda. METHODS: Women were recruited from red-light areas in Kampala. Between April 2008 and May 2009 1027 eligible women were enrolled. Sociodemographic and behavioral information were collected; blood and genital samples were tested for HIV/STI. Risk factors for HIV infection were examined using multivariate logistic regression. RESULTS: HIV seroprevalence was 37%. The prevalence of Neisseria gonorrhoeae was 13% Chlamydia trachomatis 9%; Trichomonas vaginalis 17%; bacterial vaginosis 56% and candida infection 11%. Eighty percent had herpes simplex virus 2 antibodies (HSV-2) 21% were TPHA-positive and 10% had active syphilis (RPR+TPHA+). In 3% of the genital ulcers Treponema pallidum (TP) was identified Haemophilus ducreyi in 6% and HSV-2 in 35%. Prevalent HIV was independently associated with older age being widowed lack of education sex work as sole income street-based sex work not knowing HIV-status using alcohol and intravaginal cleansing with soap. HIV infection was associated with N. gonorrhoeae T. vaginalis bacterial vaginosis HSV-2 seropositivity and active syphilis. CONCLUSIONS: Prevalence of HIV/STI is high among women involved in high-risk sexual behavior in Kampala. Targeted HIV prevention interventions including regular STI screening voluntary HIV testing and counseling condom promotion and counseling for reducing alcohol use are urgently needed in this population.

Am J Reprod Immunol 2011; 65: 368–376 The spread of HIV continues unabated in the most vulnerable populations of the world. HIV prevention methods, such as a vaginal microbicide, a mucosal vaccine, pre-exposure prophylaxis or a vaccine, are urgently needed in the fight against new infections. We must make a commitment to supporting innovative research and product design, so that one or more of these products provide a halt to the spread of HIV. Above all, these products should be proven to be safe and not negatively disturb the local immune system in a way that facilitates or enhances heterosexual transmission of HIV. HIV specific and non specific cellular and humoral local vaginal immunity must be assessed in clinical trials when testing prevention products for safety or efficacy. A proven, well-documented and standardized sampling strategy will provide high quality data to be able to assess both safety and local immune responses. In this paper, we will discuss methods for vaginal immunology sampling in the context of clinical trials.

Intravaginal and menstrual practices may potentially influence results of trials of microbicides for HIV prevention through effects on the vaginal environment and on adherence to microbicide and placebo products. As part of the feasibility study for the Microbicides Development Programme Phase 3 trial of a vaginal microbicide in Mwanza, a variety of quantitative and qualitative methods were used to describe these practices, associations with behaviour and underlying social norms among women working in food and recreational facilities. Intravaginal cleansing by inserting fingers and either water alone or soap and water was thought necessary to remove "uchafu" (dirt), referring to vaginal secretions, including menstrual blood and post-coital discharge. Vaginal cleansing was carried out within 2 hours after 45% of sex acts. Sexual enhancement practices were less common. Intravaginal and menstrual practices and associated behaviours and demographic factors should be measured and monitored throughout microbicide trials to enable analyses of their impacts on microbicide effectiveness.
