RESUMO

BACKGROUND: Little is known about penile high-risk HPV among MSM in low-and-middle income countries. We aimed to determine the incidence, clearance and persistence of penile hrHPV among Rwandan MSM. METHODS: We enrolled 350 MSM (345 with valid HPV results), aged ≥18 years, at each visit (6-12 months apart), we collected penile PreservCyt specimens and blood for HPV and HIV testing, socio-demographic and behavioral variables. HPV testing was performed using the Ampfire assay. Penile hrHPV incidence and clearance/1,000 person-months of follow-up (PMF), prevalent- and incident-persistence were computed and compared by HIV status. RESULTS: The mean age was 27.7 ± 6.7 years and 19.4% were living with HIV. Penile hrHPV incidence was 34.8 (95% CI: 29.1, 41.8)/1,000 PMF. HPV16 (11.7, CI 9.26, 14.9) and HPV59 (6.1, CI 4.52, 8.39) had the highest incidence rates. Prevalent- and incident-persistence were 47.5% and 46.6%, respectively. HPV66 (33.3%), HPV52 (30.8%) and HPV16 (29.2%) had the highest prevalent-persistence and HPV33 (53.8%), HPV31 (46.7%) and HPV16 (42.6%) the highest incident-persistence. No differences were found by HIV status except for HPV45 (higher in MSM with HIV). CONCLUSION: We found high incidence and prevalent/incident-persistence of penile hrHPV among Rwandan MSM. This highlights the importance of preventive strategies for HPV-associated anogenital cancers.

RESUMO

Introduction: Pre-exposure Prophylaxis (PrEP) is a daily pill aimed at reducing HIV transmission risk when taken as prescribed. It's highly recommended for high-risk Men who have sex with Men (MSM). This study aimed to assess PrEP awareness and willingness to use it among Rwandan MSM, a critical aspect given PrEP's proven effectiveness. The findings are expected to inform policy decisions and further advance the implementation of PrEP strategies. Methods: This is a cross-sectional study design that utilized a web-based survey conducted between April and June 2019 to assess awareness and willingness to use PrEP among sexually active MSM in Rwanda. A snowball sampling technique was used to recruit participants via social media such as WhatsApp and e-mail. Eligibility criteria included being sexually active, aged ≥18 years, self-identifying as MSM, residing in Rwanda, self-reported engagement in receptive or insertive anal sex in the last 12 months, and self-reported HIV-negative serostatus. We assessed two primary outcomes: PrEP awareness (having ever heard of PrEP) and willingness to use PrEP within one month of completing the survey. Multivariable logistic regression was performed to identify participant characteristics associated with PrEP awareness and willingness to use it. Results: Out of 521 participants, the majority (73%) demonstrated awareness of PrEP. Factors linked to PrEP awareness included residing outside the capital, Kigali, being in the 18-29 age group, having higher education levels, perceiving a benefit from PrEP, and engaging in vaginal sex with a woman while using a condom in the last year. Additionally, 96% of participants expressed a strong willingness to use PrEP. Conclusion: Rwandan MSM exhibits a high level of PrEP awareness, notably associated with factors like location, age, education, perceived benefits, and condom use. The study also revealed a strong willingness to use PrEP, indicating promising prospects for its adoption among this group. These findings highlight the need for targeted awareness campaigns, personalized interventions, and comprehensive sexual health education to promote PrEP adoption and strengthen HIV prevention efforts among Rwandan MSM.

RESUMO

BACKGROUND: While recognized as a key HIV prevention strategy, preexposure prophylaxis (PrEP) availability and accessibility are not well documented globally. We aimed to describe PrEP drug registration status and the availability of PrEP services across HIV care sites participating in the International epidemiology Databases to Evaluate AIDS (IeDEA) research consortium. METHODS: We used country-level PrEP drug registration status from the AIDS Vaccine Advocacy Coalition and data from IeDEA surveys conducted in 2014, 2017 and 2020 among participating HIV clinics in seven global regions. We used descriptive statistics to assess PrEP availability across IeDEA sites serving adult patients in 2020 and examined trends in PrEP availability among sites that responded to all three surveys. RESULTS: Of 199 sites that completed the 2020 survey, PrEP was available in 161 (81%). PrEP availability was highest at sites in North America (29/30; 97%) and East Africa (70/74; 95%) and lowest at sites in Central (10/20; 50%) and West Africa (1/6; 17%). PrEP availability was higher among sites in countries where PrEP was officially registered (146/161; 91%) than where it was not (14/32; 44%). Availability was higher at health centers (109/120; 90%) and district hospitals (14/16; 88%) compared to regional/teaching hospitals (36/63). Among the 94 sites that responded to all three surveys, PrEP availability increased from 47% in 2014 to 60% in 2017 and 76% in 2020. CONCLUSION: PrEP availability has substantially increased since 2014 and is now available at most IeDEA sites. However, PrEP service provision varies markedly across global regions.

RESUMO

HIV-related stigma in healthcare settings remains a key barrier to engaging people living with HIV (PLHIV) in care. This study investigated the association between clinical encounter frequency and HIV-related anticipated, enacted, and internalized stigma among newly-diagnosed PLHIV in Rwanda. From October 2020 to May 2022, we collected data from adult PLHIV on antiretroviral therapy (ART) in Kigali, Rwanda who were participating in a randomized, controlled trial testing early entry into differentiated care at 6 months after ART initiation. We measured anticipated HIV stigma with five-point Likert HIV Stigma Framework measures, enacted stigma with the four-point Likert HIV/AIDS Stigma Instrument, and internalized stigma with the four-point Likert HIV/AIDS Stigma Instrument. We used multivariable linear regression to test the associations between clinical encounter frequency (average inter-visit interval ≥ 50 days vs. < 50 days) and change in mean anticipated, enacted and internalized HIV stigma over the first 12 months in care. Among 93 individuals enrolled, 76 had complete data on encounter frequency and stigma measurements and were included in the present analysis. Mean internalized stigma scores of all participants decreased over the first 12 months in care. Anticipated and enacted stigma scores were low and did not change significantly over time. There was no association between encounter frequency and change in internalized stigma. In this pilot study of newly-diagnosed Rwandan PLHIV with relatively low levels of HIV-related stigma, clinical encounter frequency was not associated with change in stigma. Additional research in diverse settings and with larger samples is necessary to further explore this relationship.

RESUMO

Introduction: In utero exposure to HIV and/or triple antiretroviral therapy (ART) have been shown to be associated with preterm births and low birth weight (LBW), but data from low-resources settings with high burden of HIV remain limited. This study utilized retrospective data to describe pregnancy outcomes among Rwandan women living with HIV (WLHIV) and HIV-negative women and to assess the association of HIV and ART with LBW. Methods: This study used data from a large cohort of WLHIV and HIV-negative women in Rwanda for a cross-sectional analysis. Retrospective data were collected from antenatal care (ANC), delivery, and Prevention of Mother to Child Transmission (PMTCT) registries within the Central Africa International Epidemiology Databases to Evaluate AIDS (CA-IeDEA) in Rwanda. Data from women with documented HIV test results and known pregnancy outcomes were included in the analysis. Analyses for predictors of LBW (< 2,500 g) were restricted to singleton live births. Logistic models were used to identify independent predictors and estimate the odd ratios (OR) and 95% confidence intervals (CI) measuring the strength of their association with LBW. Results and discussion: Out of 10,608 women with known HIV status and with documented pregnancy outcomes, 9.7% (n = 1,024) were WLHIV. We restricted the sample to 10,483 women who had singleton live births for the analysis of the primary outcome, LBW. Compared with HIV-negative women, WLHIV had higher rates of stillbirth, preterm births, and LBW babies. Multivariable model showed that WLHIV and primigravidae had higher odds of LBW. Lower maternal weight and primigravidae status were associated with greater odds of LBW. Among WLHIV, the use of ART was associated with significantly lower odds of LBW in a bivariate analysis. Even in a sample of relatively healthier uncomplicated pregnancies and women who delivered in low-risk settings, WLHIV still had higher rates of poor pregnancy outcomes and to have LBW infants compared to women without HIV. Lower maternal weight and primigravidae status were independently associated with LBW. Given that supplementary nutrition to malnourished pregnant women is known to decrease the incidence of LBW, providing such supplements to lower-weight WLHIV, especially primigravidae women, might help reduce LBW.

RESUMO

Introduction: Pre-exposure Prophylaxis (PrEP) is a daily pill intended to reduce the risk of acquiring Human Immunodeficiency Virus (HIV) when taken as prescribed. It is strongly recommended for Men who have sex with Men (MSM) at high risk of HIV transmission to minimize infection risk. Despite its proven effectiveness, there is a lack of information about awareness and willingness to use PrEP among Rwandan MSM. In the context of HIV acquisition, the purpose of this study was to ascertain the awareness and willingness to use PrEP among high-risk Rwandan MSM. The findings of this research will provide valuable perspectives to mold policy and direct the effective execution of PrEP within the country. Method: This is a cross-sectional study design that utilized a web-based survey conducted between April and June 2019 to assess awareness and willingness to use PrEP among sexually active MSM in Rwanda. A snowball sampling technique was used to recruit participants who were contacted via social medial such as WhatsApp and e-mail. To be eligible, participants were supposed to be sexually active, aged ≥18 years, self-identify as MSM, residence in Rwanda, self-reported engagement in receptive or insertive anal sex in the last 12 months, and self-reported HIV-negative sero-status. We assessed two primary outcomes: PrEP awareness (having ever heard of PrEP) and willingness to use PrEP within one month of completing the survey. Multivariable logistic regression was performed to identify participant characteristics associated with PrEP awareness and willingness to use it. Results: Among the 521 participants included in the analysis, 63% were aged below 24 years. The majority (73%) demonstrated awareness of PrEP. Factors associated with PrEP awareness included residing outside of the capital, Kigali, as opposed to living in Kigali (adjusted odds ratio [aOR] 2.35, 95% confidence interval [CI] 1.40-3.97), being in the age groups 18-24 years (aOR 2.28, 95% CI: 1.03-5.01) or 25-29 years (aOR 3.06, 95% CI 1.35-6.93) compared to those aged 30 or older, having higher education levels, such as completing secondary education (aOR 1.76, 95% CI 1.01-3.06) or university education (aOR 2.65, 95% CI 1.18-5.96) in contrast to having no education. Lastly, perceiving a benefit from PrEP (aOR 9.52, 95% CI 4.27-21.22), and engaging in vaginal sex with a woman using a condom in the last 12 months (aOR 1.82, 95% CI 1.14-2.91) versus not. Impressively, 96% of participants expressed a strong willingness to use PrEP. Conclusion: Among Rwandan MSM, there is a high level of awareness of PrEP, notably associated with factors such as residing outside Kigali, younger age, higher education, perceived benefits of PrEP and condom use during vaginal sex in the past year. Furthermore, a significant portion of participants demonstrated an intense desire to use PrEP, suggesting promising possibilities for its extensive implementation among this group of people. The findings from this study emphasize the importance of implementing highly focused awareness campaigns, personalized intervention, and comprehensive sexual health education programs in order to enhance the adoption of PrEP and bolster HIV prevention initiatives among the Rwandan population of MSM.

RESUMO

BACKGROUND: 'Treat All' policies recommending immediate antiretroviral therapy (ART) soon after HIV diagnosis for all people living with HIV (PLHIV) are now ubiquitous in sub-Saharan Africa. While early ART initiation and retention is effective at curtailing disease progression and transmission, evidence suggests that stigma may act as a barrier to engagement in care. This study sought to understand the relationships between HIV stigma and engagement in care for PLHIV in Rwanda in the context of Treat All. METHODS: Between September 2018 and March 2019, we conducted semi-structured, qualitative interviews with adult PLHIV receiving care at two health centers in Kigali, Rwanda. We used a grounded theory approach to data analysis to develop conceptual framework describing how stigma influences HIV care engagement in the context of early Treat All policy implementation in Rwanda. RESULTS: Among 37 participants, 27 (73%) were women and the median age was 31 years. Participants described how care engagement under Treat All, including taking medications and attending appointments, increased their visibility as PLHIV. This served to normalize HIV and use of ART but also led to high levels of anticipated stigma in the health center and community at early stages of treatment. Enacted stigma from family and community members and resultant internalized stigma acted as additional barriers to care engagement. Nonetheless, participants described how psychosocial support from care providers and family members helped them cope with stigma and promoted continued engagement in care. CONCLUSIONS: Treat All policy in Rwanda has heightened the visibility of HIV at the individual and social levels, which has influenced HIV stigma, normalization, psychosocial support and care engagement in complex ways. Leveraging the individual and community support described by PLHIV to deliver evidence-based, peer or provider-delivered stigma reduction interventions may aid in attaining Treat All goals.

RESUMO

Introduction: The AmpFire HPV genotyping Assay (Atila Biosystems, Mountain View, CA, USA) is a new test for which there are few data regarding its analytic performance and reliability. Using anal and penile swab specimens from a cohort study of men who have sex with men (MSM) in Rwanda, we compared high-risk HPV (hrHPV) detection by AmpFire done at two laboratories, one at University of California San Francisco (UCSF) and the other Rwanda Military Hospital, and well-validated MY09/11-based assay done at UCSF. Methods: Anal and penile specimens collected from 338 MSM from March 2016 to September 2016 were tested for high-risk HPV genotypes (hrHPV) by MY09/11, AmpFire UCSF and AmpFire RMH. Cohen's kappa coefficient was used to test for reproducibility. Results: The hrHPV positivity by MY09/11 and AmpFire UCSF was 13% and 20.7% (k = 0.73) for anal specimens and was 26.3% and 32.6% (k = 0.67) for penile specimens. Specifically, good reproducibility was for types 16 and 18 (k = 0.69 and k = 0.71) for anal specimens and (k = 0.50 and k = 0.72) for penile specimens. The hrHPV positivity by AmpFire at UCSF and RMH was 20.7% for both laboratories (k = 0.87) for anal specimens and was 34.9% and 31.9% (k = 0.89) for penile specimens. Specifically, excellent reproducibility was for types 16 and 18 for anal specimens (k = 0.80 and k = 1.00) and penile specimens (k = 0.85 and k = 0.91). Conclusion: Results show that MY09/11 and AmpFire assays have good reproducibility while the AmpFire UCSF and RMH assays have excellent reproducibility. These results show that AmpFire is a promising HPV genotyping test.

RESUMO

The WHO recommends the integration of routine HIV services within maternal and child health (MCH) services to reduce the fragmentation of and to promote retention in care for pregnant and postpartum women living with HIV (WWH) and their infants and children exposed to HIV (ICEH). During 2020-2021, we surveyed 202 HIV treatment sites across 40 low- and middle-income countries within the global International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. We determined the proportion of sites providing HIV services integrated within MCH clinics, defined as full [HIV care and antiretroviral treatment (ART) initiation in MCH clinic], partial (HIV care or ART initiation in MCH clinic), or no integration. Among sites serving pregnant WWH, 54% were fully and 21% partially integrated, with the highest proportions of fully integrated sites in Southern Africa (80%) and East Africa (76%) compared to 14%-40% in other regions (i.e., Asia-Pacific; the Caribbean, Central and South America Network for HIV Epidemiology; Central Africa; West Africa). Among sites serving postpartum WWH, 51% were fully and 10% partially integrated, with a similar regional integration pattern to sites serving pregnant WWH. Among sites serving ICEH, 56% were fully and 9% were partially integrated, with the highest proportions of fully integrated sites in East Africa (76%), West Africa (58%) and Southern Africa (54%) compared to ≤33% in the other regions. Integration was heterogenous across IeDEA regions and most prevalent in East and Southern Africa. More research is needed to understand this heterogeneity and the impacts of integration on MCH outcomes globally.

RESUMO

Despite improved clinical outcomes of initiating antiretroviral therapy (ART) soon after diagnosis, conflicting evidence exists regarding the impact of same-day ART initiation on subsequent clinical outcomes. We aimed to characterize the associations of time to ART initiation with loss to care and viral suppression in a cohort of newly diagnosed people living with HIV (PLHIV) entering care after Rwanda implemented a national "Treat All" policy. We conducted a secondary analysis of routinely collected data of adult PLHIV enrolling in HIV care at 10 health facilities in Kigali, Rwanda. Time from enrollment to ART initiation was categorized as same day, 1-7 days, or >7 days. We examined associations between time to ART and loss to care (>120 days since last health facility visit) using Cox proportional hazards models, and between time to ART and viral suppression using logistic regression. Of 2,524 patients included in this analysis, 1,452 (57.5%) were women and the median age was 32 (interquartile range: 26-39). Loss to care was more frequent among patients who initiated ART on the same day (15.9%), compared with those initiating ART 1-7 days (12.3%) or >7 days (10.1%), p < .001. In multivariable analyses, same-day ART initiation was associated with a greater hazard of loss to care compared with initiating >7 days after enrollment (adjusted hazard ratio 1.39, 95% confidence interval: 1.04-1.85). A total of 1,698 (67.3%) had available data on viral load measured within 455 days after enrollment. Of these, 1,476 (87%) were virally suppressed. A higher proportion of patients initiating ART on the same day were virally suppressed (89%) compared with those initiating 1-7 days (84%) or >7 days (88%) after enrollment. This association was not statistically significant. Our findings suggest that ensuring adequate, early support for PLHIV initiating ART rapidly may be important to improve retention in care for newly diagnosed PLHIV in the era of Treat All.

RESUMO

BACKGROUND: Malaria is a public health concern worldwide. A figure of 3.2 billion people is at risk of malaria a report of World Health Organization in 2013. A proportion of 89 and 91 cases of malaria reported during 2015 were respectively attributed to malaria cases and malaria deaths in Sub-Saharan Africa. Rwanda is among the Sub-Saharan Africa located in East Africa. The several reports indicate that from 2001 to 2011, malaria cases increased considerably especially in Eastern and Southern Province with five million cases. The affected districts included Bugesera in the Eastern and Gisagara in the Southern Province of Rwanda with a share of 41% of the country prevalence in 2014 and during 2017-2018 a figure of 11 deaths was attributed to malaria and both Gisagara and Bugesera Districts were the high burdened. METHODOLOGY: The RDHS 2014-2015 data was used for the study and a cross-sectional survey was used in which two clusters were considered both Gisagara and Bugesera Districts in the Southern and Eastern Province of Rwanda. Bivariate analysis was used to determine the significant predictors with malaria and reduced logistic regression model was used. RESULTS: The results of the study show that not having mosquito bed nets for sleeping is 0.264 times less likely of having malaria than those who have mosquito bed nets in Gisagara District. In Bugesera District, living in low altitude is 2.768 times more likely associated with the risk of getting malaria than living in high altitude. CONCLUSION: The results of the study concluded that environmental and geographical factor such as low altitude is the risk factor associated with malaria than the high altitude in Bugesera District. While not having mosquito bed nets for sleeping is the protective factor for malaria than those who have it in Gisagara District. On the other hand, socio-economic and demographic characteristics do not have any effect with malaria on the results of the study.

RESUMO

INTRODUCTION: The COVID-19 pandemic has impacted population health around the globe, directly and indirectly. The objective of this study was to document changes in HIV care associated with the COVID-19 pandemic at selected clinics in Central Africa, along with clinic-level strategies for minimizing disruptions in HIV care and treatment for people with HIV (PWH). METHODS: A 51-item questionnaire on COVID-19 pandemic-associated changes in HIV service delivery was completed by clinicians involved in HIV care at 21 clinics in five countries participating in Central Africa International epidemiology Databases to Evaluate AIDS (CA-IeDEA). The survey was completed at two timepoints: June-July 2020 and October 2020 to February 2021. Descriptive statistics were used to characterize changes in HIV care and related services. RESULTS: While 81% of sites reported at least one negative consequence of COVID-19 for clinic operations during the first survey, none reported suspending antiretroviral therapy (ART) initiation services for new patients, and 24% reported adopting telemedicine. In the follow-up survey, fewer sites (48%) reported at least one disruption to clinic operations, and more sites reported mitigation strategies, including expanding rapid ART initiation services and providing extra supplies of ART medications to reduce visit frequency. In the follow-up survey, more sites, especially in Rwanda, reported stockouts of commodities, including HIV and viral load testing and HIV pre-exposure prophylaxis. More than one-fifth of sites reported stockouts of second- or third-line ART at each survey timepoint. CONCLUSIONS: While the initial wave of the COVID-19 pandemic resulted in concerning disruptions to HIV service delivery at CA-IeDEA sites, most of these disruptions attenuated over time, and many sites introduced measures to help PWH avoid frequent visits to the clinic for care and medications. The impact of HIV commodity stockouts and clinic mitigation strategies on treatment outcomes needs to be assessed.

RESUMO

INTRODUCTION: Prophylactic human papillomavirus (HPV) vaccines have been shown to be highly effective in protecting women against cervical infections, high-grade abnormalities and cancer caused by the targeted HPV types. However, the evidence for their effectiveness in women living with HIV (WLWH) is less clear. METHODS: WLWH and HIV-negative women who likely did (birth cohorts 1996 and later) and WLWH and HIV(-) negative who likely did not (birth cohorts before 1996) receive HPV vaccination (n=3028; 757 participants for each of the four groups). Between groups, we will compare cervicovaginal, anal and oral prevalent and 6-12 month persistent HPV6/11/16/18 infections as measured using a modified AmpFire HPV genotyping assay that tests for 15 high-risk or intermediate-risk HPV genotypes, HPV6 and HPV11. We will also compare the HPV immune response in HPV-vaccinated WLWH to HPV-vaccinated HIV-negative women using an anti-HPV16 and anti-HPV18 ELISA. Vaccination status will be confirmed through national vaccination records. ANALYSIS: We will calculate point prevalence and prevalence of 6-12 month persisting infections by individual HPV-type specific infections and groups of infections for each anatomic site and for each group of women. Results will be stratified by age at vaccination, age at enrolment and the number of doses (3 vs 2) as well as other factors possibly associated with HPV prevalence. Differences in endpoints between groups, overall and between subgroups, will be tested for statistical significance (p<0.05) using Fisher's exact or Pearson χ2 test. Differences in geometric mean titres and seropositivity will be tested for statistical significance using the Mann-Whitney and Fisher's exact tests, respectively. ETHICS AND DISSEMINATION: The study was approved by the Albert Einstein College of Medicine Institutional Review Board and the Rwanda National Ethics Committee. Results will be disseminated through publication in peer-reviewed journals.

RESUMO

INTRODUCTION: HIV treatment guidelines recommend that all people living with HIV (PLWH) initiate antiretroviral therapy (ART) as soon as possible after diagnosis (Treat All). As Treat All is more widely implemented, an increasing proportion of PLWH are likely to initiate ART when they are asymptomatic, and they may view the relative benefits and risks of ART differently than those initiating at more advanced disease stages. To date, patient perspectives of initiating care under Treat All in sub-Saharan Africa have not been well described. METHODS: From September 2018 to March 2019, we conducted individual, semi-structured, qualitative interviews with 37 patients receiving HIV care in two health centers in Kigali, Rwanda. Data were analyzed using a mixed deductive and inductive thematic analysis approach to describe perceived barriers to, facilitators of and acceptability of initiating and adhering to ART rapidly under Treat All. RESULTS: Of 37 participants, 27 were women and the median age was 31 years. Participants described feeling traumatized and overwhelmed by their HIV diagnosis, resulting in difficulty accepting their HIV status. Most were prescribed ART soon after diagnosis, yet fear of lifelong medication and severe side effects in the immediate period after initiating ART led to challenges adhering to therapy. Moreover, because many PLWH initiated ART while healthy, taking medications and attending appointments were visible signals of HIV status and highly stigmatizing. Nonetheless, many participants expressed enthusiasm for Treat All as a program that improved health as well as health equity. CONCLUSION: For newly-diagnosed PLWH in Rwanda, initiating ART rapidly under Treat All presents logistical and emotional challenges despite the perceived benefits. Our findings suggest that optimizing early engagement in HIV care under Treat All requires early and ongoing intervention to reduce trauma and stigma, and promote both individual and community benefits of ART.

RESUMO

INTRODUCTION: Current HIV guidelines recommend differentiated service delivery (DSD) models that allow for fewer health centre visits for clinically stable people living with HIV (PLHIV). Newly diagnosed PLHIV may require more intensive care early in their treatment course, yet frequent appointments can be burdensome to patients and health systems. Determining the optimal parameters for defining clinical stability and transitioning to less frequent appointments could decrease patient burden and health system costs. The objectives of this pilot study are to explore the feasibility and acceptability of (1) reducing the time to DSD from 12 to 6 months after antiretroviral therapy (ART) initiation,and (2) reducing the number of suppressed viral loads required to enter DSD from two to one. METHODS AND ANALYSES: The present study is a pilot, unblinded trial taking place in three health facilities in Kigali, Rwanda. Current Rwandan guidelines require PLHIV to be on ART for ≥12 months with two consecutive suppressed viral loads in order to transition to less frequent appointments. We will randomise 90 participants to one of three arms: entry into DSD at 6 months after one suppressed viral load (n=30), entry into DSD at 6 months after two suppressed viral loads (n=30) or current standard of care (n=30). We will measure feasibility and acceptability of this intervention; clinical outcomes include viral suppression at 12 months (primary outcome) and appointment attendance (secondary outcome). ETHICS AND DISSEMINATION: This clinical trial was approved by the institutional review board of Albert Einstein College of Medicine and by the Rwanda National Ethics Committee. Findings will be disseminated through conferences and peer-reviewed publications, as well as meetings with stakeholders. TRIAL REGISTRATION NUMBER: NCT04567693.

RESUMO

BACKGROUND: Persistent infection with high-risk human papillomavirus (hrHPV) is a critical step in cervical carcinogenesis. We report on type-specific hrHPV persistence, clearance and incidence among screen-positive Rwandan women living with HIV (WLWH). METHODS: This was a nested analysis from a large cervical cancer screening study of ~ 5000 Rwandan WLWH. Women who tested positive for hrHPV and/or visual inspection with acetic acid were referred to colposcopy. For a subset of women (n = 298) who were ≥ 6 months delayed in receiving colposcopy, we tested their screening and colposcopy visit specimens using the AmpFire HPV genotyping assay that tests 14 hrHPV types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) individually. RESULTS: The mean, median (interquartile range [IQR]) and range of time between the screening and colposcopy visits were 644, 650 (490-820.5) and 197-1161 days, respectively. Mean, median (IQR) and range of age at the screening visit were 38, 37 (34-43) and 30-54 years, respectively. Two-hundred eighty-three (95.0%) had CD4 count (cells per mm3) data available at baseline with mean, median (IQR) and range of 592, 513 (346-717) and 0-7290, respectively. Two-hundred thirty-five WLWH were positive for at least one hrHPV type at the screening visit, of whom 50.2% had at least one HPV type-specific infection persist; 37.2% of all HPV infections detected at the screening visit persisted. Compared to all other HPV types in aggregate, HPV16 (vs. non-HPV16 types) (47.7%, p = 0.03) and HPV33 (vs. non-HPV33 types) (56.7%, p = 0.03) were significantly more likely, and HPV39 (vs. non-HPV39 types) (6.7%, p = 0.01), HPV51 (vs. non-HPV51 types) (15.6%, p < 0.01), and HPV66 (vs. non-HPV66 types (17.9%, p = 0.04) were significantly less likely, to persist. Lower CD4 counts were associated with having any persistent hrHPV infection (ptrend = 0.04) and multiple persistent hrHPV infections (ptrend = 0.04). CONCLUSION: There is a significant proportion of WLWH with persistent hrHPV infection, emphasizing the need to vaccinate them against HPV prior to becoming sexually active.

RESUMO

To address gaps in access to cervical cancer screening and early diagnosis of breast cancer services in Sub-Saharan African (SSA), this scoping review was conducted to explore facilitators and barriers that exist on the patient-, provider-, and system-level. An extensive literature search was conducted in accordance with scoping review methodology and the Cochrane guidelines. Our search criteria were limited to original research studies conducted in community or clinical settings in SSA within the last 10 years (2010-2020). Themes found from this review included patient knowledge and provider education, access to screening services, trust, health-related behaviors, attitudes, values, and practices, community and social values, health infrastructure, resource allocation, and political will. Identified barriers included lack of knowledge about cervical and breast cancer among patients, gaps in education and training among providers, and lack of resources and health infrastructure at the facility level and within the overall health system. Facilitators included perceived risk of cancer, support and encouragement of the provider, and utilization of novel approaches in low-resource settings by health systems. To better address individual-, provider-, and health system and facility-based facilitators and barriers to care, there is a need for political and financial investment and further research on the health service delivery in specific national health systems, especially in the context of the global campaign to eliminate cervical cancer as a public health problem.

RESUMO

BACKGROUND: Men who have sex with men (MSM) have a high prevalence of anal and penile human papillomavirus (HPV) infections with MSM living with HIV (MSMLH) bearing the highest rates. Data on anogenital high-risk HPV (hrHPV) among MSM in Rwanda and the associated risk factors are scant. METHODS: We recruited 350 self-identified MSM aged 18 years living in Kigali, Rwanda, with 300 recruited from the community and 50 from partner clinics. Anal and penile specimens from all participants were analyzed for hrHPV using the AmpFire platform. Logistic regression was used to calculate crude odds ratios (ORs) and adjusted ORs (aORs) with 95% confidence intervals (95% CIs) as a measure of association between various factors and anal and penile hrHPV infection prevalence. RESULTS: Anal hrHPV prevalence was 20.1%, was positively associated with having receptive anal sex with more partners (aOR: 9.21, 95% CI: 3.66 to 23.14), and was negatively associated with having insertive anal sex with more partners (aOR: 0.28, 95% CI: 0.12 to 0.66). Penile hrHPV prevalence was 35.0%, was negatively associated with having receptive anal sex with more partners (aOR: 0.29, 95% CI: 0.13 to 0.66), and differed significantly by HIV status, with 55.2% and 29.7% for MSMLH and HIV-negative MSM, respectively (P < 0.01). CONCLUSION: Penile hrHPV prevalence was higher than that of anal hrHPV and it was significantly higher in Rwandan MSMLH than in HIV-negative MSM. The prevalence of anal and penile HPV infections is likely variable at different locations in Africa, according to a number of factors including HIV status and sexual practices.

RESUMO

INTRODUCTION: Aiming to reach UNAIDS 90-90-90 targets, nearly all sub-Saharan African countries have expanded antiretroviral therapy (ART) to all people living with HIV (PLWH) (Treat All). Few published data exist on viral load testing and viral suppression under Treat All in this region. We assessed proportions of patients with available viral load test results and who were virally suppressed, as well as factors associated with viral suppression, among PLWH in 10 Rwandan health centres after Treat All implementation. METHODS: Cross-sectional study during 2018 of adults (≥15 years) engaged in HIV care at 10 Rwandan health centres. Outcomes were being on ART (available ART initiation date in the study database, with no ART discontinuation prior to 1 January 2018), retained on ART (≥2 post-ART health centre visits ≥90 days apart during 2018), available viral load test results (viral load measured in 2018 and available in study database) and virally suppressed (most recent 2018 viral load <200 copies/mL). We used modified Poisson regression models accounting for clustering by health centre to determine factors associated with being virally suppressed. RESULTS: Of 12,238 patients, 7050 (58%) were female and 1028 (8%) were aged 15 to 24 years. Nearly all patients (11,933; 97%) were on ART, of whom 11,198 (94%) were retained on ART. Among patients retained on ART, 10,200 (91%) had available viral load results; of these 9331 (91%) were virally suppressed. Viral suppression was less likely among patients aged 15 to 24 compared to >49 years (adjusted prevalence ratio (aPR): 0.83, 95% CI 0.76 to 0.90 and those with pre-ART CD4 counts of <200 compared to ≥500 cells/mm3 (aPR: 0.92, 95% CI 0.90 to 0.93). There was no statistically significant difference in viral suppression among patients who entered after Treat All implementation compared to those who enrolled before 2010 (aPR 0.98, 95% CI 0.94 to 1.03). CONCLUSIONS: In this large cohort of Rwandan PLWH receiving HIV care after Treat All implementation, patients in study health centres have surpassed the third UNAIDS 90-90-90 target. To ensure all PLWH fully benefit from ART, additional efforts should focus on improving ART adherence among younger persons.
