RESUMO

OBJECTIVES: Live biotherapeutic products (LBPs) containing vaginal Lactobacillus crispatus are promising adjuvant treatments to prevent recurrent bacterial vaginosis (BV) but may depend on the success of initial antibiotic treatment. METHODS: A post hoc analysis of data collected during the phase 2b LACTIN-V randomized control trial (L. crispatus CTV-05) explored the impact of clinical BV cure defined as Amsel criteria 0 of 3 (excluding pH, per 2019 Food and Drug Administration guidance) 2 days after completion of treatment with vaginal metronidazole gel on the effectiveness of an 11-week LACTIN-V dosing regimen to prevent BV recurrence by 12 and 24 weeks. RESULTS: At enrollment, 88% of participants had achieved postantibiotic clinical BV cure. The effect of LACTIN-V on BV recurrence compared with placebo differed by initial clinical BV cure status. The LACTIN-V to placebo risk ratio of BV recurrence by 12 weeks was 0.56 (95% confidence interval, 0.35-0.77) among participants with initial clinical BV cure after metronidazole treatment and 1.34 (95% confidence interval, 0.47-2.23) among participants without postantibiotic clinical BV cure. Among women receiving LACTIN-V, those who had achieved postantibiotic clinical BV cure at enrollment reached higher levels of detectable L. crispatus CTV-05 compared with women failing to achieve postantibiotic clinical BV cure. CONCLUSIONS: LACTIN-V seems to only decrease BV recurrence in women with clinical cure of BV after initial antibiotic treatment. Future trials of LBPs should consider limiting enrollment to these women.

RESUMO

OBJECTIVE: HIV stigma undermines antiretroviral treatment (ART) adherence and viral suppression. Livelihood interventions may target drivers of negative attitudes towards people living with HIV (PLHIV) by improving their health and strengthening their economic contributions. We examined the effects of a multisectoral agricultural livelihood intervention on HIV stigma among PLHIV in western Kenya. DESIGN: Sixteen health facilities were randomly allocated (1:1) to intervention or control arms in Shamba Maisha, a cluster randomized controlled trial that aimed to improve HIV-related health through behavioral, mental health, and nutritional pathways. METHODS: The intervention included a farming loan and agricultural and financial training. Participants had access to farmland and surface water and were ≥18 years old, on ART >six months, and moderately-to-severely food insecure. We measured internalized, anticipated, and enacted HIV stigma semiannually over two years using validated scales. In blinded intent-to-treat analyses, we compared changes in scores over 24 months, by study arm, using longitudinal multi-level difference-in-differences linear regression models that accounted for clustering. RESULTS: Of 720 enrolled participants (354 intervention), 55% were female, and the median age was 40 years (interquartile range 34-47 years). Two-year retention was 94%. Compared to the control arm, the intervention resulted in significant decreases (p < 0.001) of 0.42 points (95% confidence interval (CI) -0.52, -0.31) in internalized stigma, 0.43 points (95% CI -0.51, -0.34) in anticipated stigma, and 0.13 points (95% CI -0.16, -0.09) in enacted stigma over 24 months. CONCLUSIONS: The agricultural livelihood intervention reduced HIV stigma among PLHIV. Poverty-reduction approaches may be a novel strategy for reducing HIV stigma.

RESUMO

Understanding risk perception and risk-taking among youth can inform targeted prevention efforts. Using a health beliefs model-informed framework, we analysed 8 semi-structured, gender-specific focus group discussions with 93 youth 15-24 years old (48% male, 52% female), drawn from the SEARCH trial in rural Kenya and Uganda in 2017-2018, coinciding with the widespread introduction of PrEP. Highly connected social networks and widespread uptake of antiretrovirals shaped youth HIV risk perception. Amid conflicting information about HIV prevention methods, youth felt exposed to multiple HIV risk factors like the high prevalence of HIV, belief that people with HIV(PWH) purposefully infect others, dislike of condoms, and doubts about PrEP efficacy. Young women also reported minimal sexual autonomy in the context of economic disadvantages, the ubiquity of intergenerational and transactional sex, and peer pressure from other women to have many boyfriends. Young men likewise reported vulnerability to intergenerational sex, but also adopted a sexual conquest mentality. Comprehensive sexuality education and economic empowerment, through credible and trusted sources, may moderate risk-taking. Messaging should leverage youth's social networks to spread fact-based, gender- and age-appropriate information. PrEP should be offered alongside other reproductive health services to address both pregnancy concerns and reduce HIV risk.

RESUMO

PURPOSE: To achieve the WHO cervical cancer elimination targets, countries globally must achieve 70% cervical cancer screening (CCS) coverage. We evaluated CCS uptake and predictors of screening positive at two public HIV care programs in western Kenya. METHODS: From October 2007 to February 2019, data from the Family AIDS Care and Education Services (FACES) and Academic Model Providing Access to Healthcare (AMPATH) programs in western Kenya were analyzed. The study population included women age 18-65 years enrolled in HIV care. Screening uptake was calculated annually and overall, determining the proportion of eligible women screened. Multivariate logistic regression assessed predictors of positive screening outcomes. RESULTS: There were 57,298 women living with HIV (WLWHIV) eligible for CCS across both programs during the study period. The mean age was 31.4 years (IQR, 25.9-37.8), and 39% were on antiretroviral therapy (ART) at the first CCS-eligible visit. Of all eligible women, 29.4% (95% CI, 29.1 to 29.8) underwent CCS during the study period, 27.0% (95% CI, 26.5 to 27.4) in the AMPATH program, and 35.6% (95% CI, 34.9 to 36.4) in the FACES program. Annual screening uptake varied greatly in both programs, with coverage as low as 1% of eligible WLWHIV during specific years. Age at first screening, CD4 count within 90 days of screening, current use of ART, and program (AMPATH v FACES) were each statistically significant predictors of positive screening. CONCLUSION: CCS uptake at two large HIV care programs in Kenya fell short of the WHO's 70% screening target. Screening rates varied significantly on the basis of the availability of funding specific to CCS, reflecting the limitations of vertical funding programs.

RESUMO

BACKGROUND: HIV pre-exposure prophylaxis (PrEP) is an effective prevention tool; however, use among adolescents is thought to be low. To determine the unmet need and opportunity to expand use, we assessed awareness, prior use, and willingness to take PrEP among Kenyan adolescents. METHODS: The Maneno Yetu study recruited a community-based sample of adolescents aged 15-19 years (N = 3061) in Kisumu for a survey using respondent-driven sampling. RESULTS: Overall, 50% of adolescents had heard of PrEP and 2% had used PrEP. Girls were more likely than boys to have heard of PrEP (53.4% vs. 45.1%; P < 0.001) and used PrEP (3.6% vs. 0.3%; P < 0.001). Among participants, 14% engaged in transactional sex and 21% experienced forced sexual contact. PrEP use was higher among adolescents who engaged in transactional sex (4.8% vs. 0.6%; P < 0.001) and experienced forced sexual contact (2.7% vs. 0.7%; P < 0.001) compared with those who did not. Among adolescents with no prior use, 53% were willing to consider using PrEP, although girls were less willing than boys (49.7% vs. 55.9%; P = 0.001). CONCLUSIONS: PrEP is an important prevention tool, especially for adolescents whose circumstances potentially expose them to HIV-positive or unknown status sexual partners, yet remains underused, particularly in resource-limited settings. Although many expressed willingness to use PrEP, low awareness and use highlight the need to expand HIV prevention education and services tailored for adolescents. Our finding that boys were more willing to use PrEP suggests campaigns should also be designed to reach male youth to narrow the gender gap and expand uptake in the adolescent population.

RESUMO

OBJECTIVE: To evaluate the impact of an agricultural livelihood intervention on gender role conflict and sexual relationship power among people with HIV (PWH) in western Kenya. DESIGN: Study participants were enrolled in Shamba Maisha , a cluster randomized controlled trial of an agricultural intervention conducted among PWH across 16 health facilities during 2016-2020. Intervention participants received a water pump, seeds, and agricultural and financial training; control participants received standard of HIV care. METHODS: We assessed men's views on masculinity and gender roles via the validated gender role conflict score (GRCS; range 18-78, higher = greater gender role conflict). We measured gender power imbalances among women via the validated Sexual Relationship Power Scale (SRPS), which combines subscales of relationship control and decision-making dominance (range 1-4, higher = female holds more power). We compared changes over the study period by arm using longitudinal multilevel difference-in-difference linear regression models accounting for clustering of facilities using the intention-to-treat cohort. RESULTS: We enrolled 720 participants (366 intervention, 354 control); 2-year retention was 94%. Median age was 40 and approximately 55% of participants were female. Among men, after 24-months the decrease in GRCS scores was 4.3 points greater in the intervention than the control arm ( P  < 0.001). Among women, the intervention resulted in 0.25 points greater increase in the SRPS compared to the control arm ( P  < 0.001). CONCLUSIONS: Shamba Maisha resulted in less gender role conflict in men and greater sexual relationship power for women. Agricultural livelihood interventions may be a powerful tool to improve gender power imbalances, which may subsequently mitigate poverty and food insecurity.

RESUMO

BACKGROUND: The syndemic effects of poverty, food insecurity and living with HIV are recognized as global health priorities, including through the United Nations Sustainability Goals 1, 2 and 3. Today, women and girls account for 63% of all new HIV infections in eastern and southern Africa, including Kenya. Pregnant and postpartum women living with HIV in this setting face unique challenges including increased financial insecurity as women leave the work force to care for their newborn infants. This contributes to poverty, food scarcity and stress. METHODS: To address financial insecurity, improve infant feeding and reduce stress among mothers living with HIV in this setting, we developed a multilevel intervention, Supporting Healthy Mothers, consisting of 10 monthly unconditional cash transfers (10,000 KES, ~$75 USD/month) and personalized infant feeding support from pregnancy to 7 months postpartum. We conducted a non-randomized feasibility trial of this intervention among women engaged in HIV care in Kisumu, Kenya. From February 23, 2022 to March 23, 2022, we enrolled a total of 40 women who were 20-35 weeks pregnant-20 women to the intervention group at a public clinic, and 20 women to the control group at a similar clinic. Our aim was to assess feasibility, acceptability, and the potential impact of the intervention on food security, infant feeding and maternal mental health. RESULTS: Analyzing data from all 40 participants, we found a significant reduction in food insecurity scores from baseline for the intervention group when compared to the control group at 6 weeks and 6 months postpartum (p = 0.0008 and p < 0.0001, respectively). Qualitative exit interviews with intervention group participants confirmed women felt more financially secure and had newly acquired practical knowledge and skills related to infant feeding. Women found the two intervention components highly acceptable and described an overall positive impact on wellbeing. CONCLUSIONS: The Supporting Healthy Mothers intervention has potential to positively impact women across the perinatal period and beyond by increasing financial security and supporting women to overcome infant feeding challenges and should be assessed in larger trials. TRIAL REGISTRATION: Supporting Healthy Mothers was registered with ClinicalTrials.gov Protocol Registration and Results System, initially published on February 1, 2022. CLINICALTRIALS: gov ID: NCT05219552 Protocol ID: K23MH116807.

RESUMO

BACKGROUND: Adolescent girls may experience poor psychological well-being, such as social isolation, shame, anxiety, hopelessness, and despair linked to food insecurity. OBJECTIVES: This study aimed to investigate the experiences with and perceived effects of a household-level income-generating agricultural intervention on the psychological well-being of adolescent girls in human immunodeficiency virus (HIV)-affected households in southwestern Kenya. METHODS: We conducted 62 in-depth interviews with HIV-affected adolescent girls and caregiver dyads in Adolescent Shamba Maisha (NCT03741634), a sub-study of adolescent girls and caregivers with a household member participating in Shamba Maisha (NCT01548599), a multisectoral agricultural and finance intervention trial aimed to improve food security and HIV health indicators. Participants were purposively sampled to ensure diversity in terms of age and location. Data were audiotaped, transcribed, translated, and uploaded into Dedoose (Sociocultural Research Consultants, LLC) software for management. Data were analyzed thematically based on reports from Dedoose. RESULTS: We found evidence that a household-level structural intervention aimed at increasing food and financial security among persons living with HIV can contribute to better psychological well-being among adolescent girls residing in these households. The intervention also affected: 1) reduction of social isolation, 2) reduction of shame and stigma, 3) increased attendance and concentration in school, 4) improved caregiver mental health, and 5) reduced parental aggression and improved household communication. These associations were reported more commonly among those in the intervention arm than the control arm. CONCLUSIONS: This study extends existing research by demonstrating how multisectoral structural interventions delivered at a household level can improve the psychological well-being of adolescents. We recommend that future research test livelihood interventions designed specifically for adolescent girls that integrate food-security interventions with other elements to address the social and psychological consequences of food insecurity holistically. This trial was registered at clinicaltrials.gov as NCT03741634.

RESUMO

The World Health Organization recommends thermal ablation (TA) as an alternative to cryotherapy within "screen-and-treat" cervical cancer programs in low- and middle-income countries (LMICs), including among women living with HIV (WLWH). Data on TA efficacy among WLWH are limited, however. We conducted a clinical trial to evaluate efficacy of TA for treatment of biopsy-confirmed cervical intraepithelial neoplasia grades 2 and 3 (CIN2/3) among WLWH in Kenya. Nonpregnant HPV-positive WLWH age 25 to 65 years underwent colposcopy-directed biopsy, and same-day treatment with TA, if eligible. Women with biopsy-confirmed CIN2/3 at baseline had colposcopy-directed biopsies at 12 months to determine cure. A total of 376 participants underwent TA during the study period. At baseline, 238 (63.3%) had normal histology, 39 (10.4%) had CIN1, 15 (4.0%) had CIN2, 55 (14.6%) had CIN3, 7 (1.9%) had microinvasive cancer and 22 (5.6%) had indeterminate results. Twelve-month follow-up pathology results are available for 59 of 70 (84.3%) participants with CIN2/3 at baseline. Of these, 39 (66.1%, 95% CI 0.54-0.99) had successful treatment, defined as biopsy-confirmed CIN1 or normal findings, while 20 (33.9%, 95% CI 0.22-0.46) had treatment failure, defined as persistent biopsy-confirmed CIN2 or worse. Treatment failure was 23.1% (95% CI 0.17-0.46) and 39.9% (95% CI 0.23-0.51) among women with CIN2 and CIN3 at baseline, respectively. HIV-positive women with CIN2/3 have high rates of treatment failure at 1-year following thermal ablation. This highlights a significant limitation in the current WHO cervical cancer secondary-prevention strategy and calls for strategies to optimize cervical precancer treatment in this population.

RESUMO

Adolescents comprise approximately 15% of new HIV infections in Kenya. Impoverished living conditions in informal settlements place residents at high risk for HIV infection. We assessed factors associated with HIV infection among adolescents residing in urban informal settlements in Kisumu. We recruited 3,061 adolescent boys and girls aged 15-19. HIV prevalence was 2.5% overall, all newly identified cases were among girls and infection was positively associated with not completing a secondary education (p < .001). Girls who had ever been pregnant (p < .001) or out-of-school without completing a secondary education (p < .001) were more likely to be HIV-positive. Our findings of higher HIV prevalence among adolescent girls who had been pregnant or did not complete secondary school highlight the need to facilitate access to HIV testing, HIV pre-exposure prophylaxis, and sexual and reproductive health services as components of a comprehensive prevention strategy to decrease HIV infections in this priority population.

RESUMO

INTRODUCTION: Widowed women make up 18-40% of the 12 million women living with HIV in eastern and southern Africa. Widowhood has also been associated with greater HIV morbidity and mortality. We compared the effectiveness of a multisectoral climate adaptive agricultural livelihood intervention (called Shamba Maisha) on food insecurity, and HIV related health outcomes among widowed and married women living with HIV in western Kenya. METHODS: We implemented Shamba Maisha (NCT02815579) using a cluster-randomized control trial design. The intervention arm received an US$175 in-kind loan to purchase a micro-irrigation pump, seeds, and fertilizer, and received eight training sessions on sustainable agriculture and financial management. Study outcomes were measured every 6 months over a 24-month follow-up period and trends in outcomes assessed using multilevel mixed-effects models. RESULTS: The trial enrolled 232 (61.5%) married and 145 (38.5%) widowed women. Widowed women (mean age 42.8 ± 8.4 years) were older than married women (35.8 ± 9.0 years) (p < 0.01). Almost all widowed women (97.2%) self-identified as household heads compared to 10.8% of married women. Comparing widowed vs married women, reduction in food insecurity (-3.13, 95%CI -4.42, -1.84 vs. -3.08, 95%CI -4.15, -2.02), depressive symptoms (-0.21, 95%CI -0.36, -0.07 vs. -0.19, 95%CI -0.29, -0.08), internalized stigma (-0.33, 95%CI -0.55, -0.11 vs. -0.38, 95%CI -0.57, -0.19), and anticipated stigma (-0.46 95%CI -0.65, -0.28 vs. -0.35, 95%CI -0.50, -0.21) was similar for both groups. In contrast, improvements in social support (-2.22, 95%CI -3.85, -0.59 vs. -4.00, 95%CI -5.16, -2.84; p = 0.08) and reduction in enacted stigma (0.01, 95%CI -0.06, 0.08 vs. -0.14, 95%CI -0.20, -0.09; p < 0.01) were weaker for widowed than married women. CONCLUSIONS: Our study is among the first comparing the effect of a livelihood intervention on HIV health outcomes among widowed and married women. Widowed women experienced similar benefits as married women on individual-level outcomes, but weaker benefit on outcomes dependent on their external environment like enacted stigma and social support. Future trials and programs targeting widowed women should bolster stigma reduction and social support.

RESUMO

OBJECTIVES: Determine whether patient-centered, streamlined HIV care achieves higher antiretroviral therapy (ART) uptake and viral suppression than the standard treatment model for people with HIV (PWH) reporting hazardous alcohol use. DESIGN: Community cluster-randomized trial. METHODS: The Sustainable East Africa Research in Community Health trial (NCT01864603) compared an intervention of annual population HIV testing, universal ART, and patient-centered care with a control of baseline population testing with ART by country standard in 32 Kenyan and Ugandan communities. Adults (15 years or older) completed a baseline Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) and were classified as no/nonhazardous (AUDIT-C 0-2 women/0-3 men) or hazardous alcohol use (≥3 women/≥4 men). We compared year 3 ART uptake and viral suppression of PWH reporting hazardous use between intervention and control arms. We compared alcohol use as a predictor of year 3 ART uptake and viral suppression among PWH, by arm. RESULTS: Of 11,070 PWH with AUDIT-C measured, 1723 (16%) reported any alcohol use and 893 (8%) reported hazardous use. Among PWH reporting hazardous use, the intervention arm had higher ART uptake (96%) and suppression (87%) compared with control (74%, adjusted risk ratio [aRR] = 1.28, 95% CI: 1.19 to 1.38; and 72%, aRR = 1.20, 95% CI: 1.10 to 1.31, respectively). Within arm, hazardous alcohol use predicted lower ART uptake in control (aRR = 0.86, 95% CI: 0.78 to 0.96), but not intervention (aRR = 1.02, 95% CI: 1.00 to 1.04); use was not predictive of suppression in either arm. CONCLUSIONS: The Sustainable East Africa Research in Community Health intervention improved ART uptake and viral suppression among PWH reporting hazardous alcohol use and eliminated gaps in ART uptake between PWH with hazardous and no/nonhazardous use. Patient-centered HIV care may decrease barriers to HIV care for PWH with hazardous alcohol use.

RESUMO

Non-disclosure of human immunodeficiency virus (HIV) status can hinder optimal health outcomes for people living with HIV (PLHIV). We sought to explore experiences with and correlates of disclosure among PLHIV participating in a study of population mobility. Survey data were collected from 1081 PLHIV from 2015-16 in 12 communities in Kenya and Uganda participating in a test-and-treat trial (SEARCH, NCT#01864603). Pooled and sex-stratified multiple logistic regression models examined associations of disclosure with risk behaviors controlling for covariates and community clustering. At baseline, 91.0% (n = 984) of PLHIV had disclosed their serostatus. Amongst those who had never disclosed, 31% feared abandonment (47.4% men vs. 15.0% women; p = 0.005). Non-disclosure was associated with no condom use in the past 6 months (aOR = 2.44; 95%CI, 1.40-4.25) and with lower odds of receiving care (aOR = 0.8; 95%CI, 0.04-0.17). Unmarried versus married men had higher odds of non- disclosure (aOR = 4.65, 95%CI, 1.32-16.35) and no condom use in the past 6 months (aOR = 4.80, 95%CI, 1.74-13.20), as well as lower odds of receiving HIV care (aOR = 0.15; 95%CI, 0.04-50 0.49). Unmarried versus married women had higher odds of non-disclosure (aOR = 3.14, 95%CI, 1.47-6.73) and lower odds of receiving HIV care if they had never disclosed (aOR = 0.05, 95%CI, 0.02-0.14). Findings highlight gender differences in barriers to HIV disclosure, use of condoms, and engagement in HIV care. Interventions focused on differing disclosure support needs for women and men are needed and may help facilitate better care engagement for men and women and improve condom use in men.

RESUMO

Exclusive breastfeeding for the first 6 months and continued breastfeeding for 24 months or longer is recommended for all mothers world-wide, including women living with HIV (WLWH). Given evidence of suboptimal infant feeding and the need to understand context specific barriers, we explored experiences of perinatal WLWH in Kisumu, Kenya. We applied a longitudinal qualitative approach (4 in-depth interviews) with 30 women from pregnancy to 14-18 months postpartum. Cross-sectional profiling led to a narrative description of infant feeding across time. The majority of women breastfed exclusively for 6 months and weaned by 18 months. Severe financial and food insecurity were primary challenges as women worked through when/how to breastfeed or stop breastfeeding in the setting of multiple competing priorities/pressures across time. Financial and food support and increased support for breastfeeding beyond 18 months have the potential to reduce women's stress and uncertainty associated with infant feeding as well as optimize infant health and nutrition in this setting.


RESUMEN: Se recomienda la lactancia materna exclusiva durante los primeros 6 meses y la continuación de la lactancia durante 24 meses o más para todas las madres en todo el mundo, incluidas las mujeres que viven con el VIH (WLWH). Debido a la evidencia de alimentación infantil subóptima y la necesidad de comprender las barreras específicas del contexto, exploramos las experiencias de WLWH perinatal en Kisumu, Kenia. Aplicamos un enfoque cualitativo longitudinal (4 entrevistas en profundidad) con 30 mujeres desde el embarazo hasta los 14-18 meses posparto. El perfil transversal resultó en una descripción narrativa de la alimentación infantil a través del tiempo. La mayoría de las mujeres amamantaron exclusivamente durante 6 meses y dejó de amamantar a los 18 meses. La grave inseguridad financiera y alimentaria fueron los principales desafíos cuando las mujeres analizaban cuándo y cómo amamantar o dejar de amamantar en el contexto de múltiples prioridades y presiones en competencia a través del tiempo. El apoyo financiero y alimentario y un mayor apoyo para la lactancia más allá de los 18 meses tienen el potencial de reducir el estrés y la incertidumbre de las mujeres asociados con la alimentación infantil, así como optimizar la salud y la nutrición infantil en este entorno.

RESUMO

Safer conception services are needed to minimize HIV transmission among HIV sero-different couples desiring pregnancy. Few studies have evaluated the choices couples make when offered multiple safer conception methods or real-world method acceptability and effectiveness. We piloted a comprehensive safer conception program (Clintrials.gov identifier: NCT03049176) for HIV sero-different couples planning pregnancy in Zimbabwe to measure feasibility, method uptake, acceptability, pregnancy outcome, and HIV transmission. This study was not designed to compare rates of HIV transmission by safer conception method choice but rather to understand choices couples make when seeking to minimize risk of HIV transmission and maximize likelihood of pregnancy. Couples in this prospective, non-randomized study were given a choice of one or more currently available safer conception methods: antiretroviral therapy (ART) with monthly viral load (VL) monitoring for the HIV-positive partner (ART/VL), pre-exposure prophylaxis (PrEP) for the HIV-negative partner, vaginal insemination (VI) for couples with an HIV-positive woman, and semen washing (SW) for couples with an HIV-positive man. Couples were followed monthly for up to 12 months of pregnancy attempts, quarterly during pregnancy, and 12 weeks post-partum. At each visit, data on method use, urine for pregnancy testing, and blood for HIV antibody testing, or viral load if HIV-positive, were obtained. Infants born to HIV-positive women were tested for HIV at 6 and 12 weeks. Between March 2017 and June 2019, 46 individuals from 23 HIV sero-different partnerships were enrolled and followed. At enrollment, all couples chose ART/VL, and all couples chose at least one additional method; 74% chose PrEP, 36% chose SW, and 25% chose VI. During pre-pregnancy follow-up visits, three couples discontinued SW, and one couple discontinued VI; all four of these couples opted for ART/VL plus PrEP. Satisfaction with safer conception methods was high among those who chose ART/VL and PrEP. Twelve couples achieved pregnancy. There were no cases of HIV transmission to partners, and no infants tested positive for HIV. This safer conception program is feasible and acceptable, allowing sero-different couples to safely achieve pregnancy. Sero-different couples in Zimbabwe seek a combination of HIV prevention methods, particularly ART/VL plus PrEP. Trial Registration: Clintrials.gov, NCT03049176.

RESUMO

Voluntary male medical circumcision (VMMC) reduces HIV acquisition by up to 60%. Kenya has successfully scaled up VMMC to an estimated 91% of eligible men and boys in certain regions in combination due to VMMC and cultural circumcisions. VMMC as a program is implemented regionally in traditionally non-circumcising counties where the prevalence is still below 91%, ranging from 56.4% to 66.7%. Given that funding toward VMMC is expected to decline in the coming years, it is important to identify what models of service delivery are most appropriate and efficient to sustainably meet the VMMC needs of new cohorts' eligible men. To this end, we compared the costs of facility-based VMMC and one within a rapid results initiative (RRI), a public health service scheduled during school holidays to perform many procedures over a short period. We employed activity-based micro-costing to estimate the costs, from the implementer perspective, of facility-based VMMC and RRI-based VMMC conducted between October 2017 and September 2018 at 41 sites in Kisumu County, Kenya supported by the Family AIDS care & Education Services (FACES). We conducted site visits and reviewed financial ledger and programmatic data to identify and quantify resources consumed and the number of VMMC procedures performed during routine care and RRIs. Ledger data were used to estimate fixed costs, recurring costs, and cost per circumcision (CPC) in United States dollar (USD). A sensitivity analysis was done to estimate CPC where we allocated 6 months of the ledger to facility-based and 6 months to RRI. Overall, FACES spent $3,092,891 toward VMMC services and performed 42,139 procedures during the funding year. This included $2,644,910 in stable programmatic costs, $139,786 procedure costs, and $308,195 for RRI-specific activities. Over the year, 49% (n = 20,625) of procedures were performed as part of routine care and 51% (n = 21,514) were performed during the RRIs. Procedures conducted during facility-based cost $99.35 per circumcision, those conducted during the RRIs cost $48.51 per circumcision, and according to our sensitivity analysis, CPC for facility-based ranges from $99.35 to $287.24 and for RRI costs ranged from $29.81 to $48.51. The cost of VMMC during the RRI was substantially lower than unit costs reported in previous costing studies. We conclude that circumcision campaigns, such as the RRI, offer an efficient and sustainable approach to VMMC.

RESUMO

Background: Bacterial vaginosis (BV) is a proinflammatory genital condition associated with adverse reproductive health outcomes, including increased HIV incidence. However, BV recurrence rates are high after standard antibiotic treatment. While the composition of the vaginal microbiota before BV treatment may be linked to BV recurrence, it is unclear whether the preceding genital immune milieu is predictive of treatment success. Methods: Here we assessed whether baseline vaginal soluble immune factors or the composition of the vaginal microbiota predicted treatment success 1 month after metronidazole treatment in 2 separate cohorts of women with BV, 1 in the United States and 1 in Kenya; samples within 48 hours of BV treatment were also available for the US cohort. Results: Neither soluble immune factors nor the composition of the vaginal microbiota before BV treatment was associated with treatment response in either cohort. In the US cohort, although the absolute abundances of key vaginal bacterial taxa pretreatment were not associated with treatment response, participants with sustained BV clearance had a more pronounced reduction in the absolute abundance of Gardnerella vaginalis immediately after treatment. Conclusions: Pretreatment immune and microbial parameters were not predictive of BV treatment success in these clinical cohorts.

RESUMO

BACKGROUND: Population mobility is prevalent and complex in sub-Saharan Africa, and can disrupt HIV care and fuel onward transmission. While differentiated care models show promise for meeting the needs of mobile populations by addressing care cascade gaps, the voices of mobile populations need to be included when designing care delivery models. We assessed the unmet needs of mobile populations and engaged mobile stakeholders in the design and implementation of service delivery to improve care outcomes for mobile people living with HIV (PLHIV). METHODS: CBPR was conducted in 12 rural communities in Kenya and Uganda participating in a mobility study within the Sustainable East Africa Research in Community Health (SEARCH) test-and-treat trial (NCT# 01864603) from 2016 to 2019. Annual gender-balanced meetings with between 17 and 33 mobile community stakeholders per meeting were conducted in local languages to gather information on mobility and its influence on HIV-related outcomes. Discussions were audio-recorded, transcribed and translated into English. Findings were shared at subsequent meetings to engage mobile stakeholders in interpretation. At year three, intervention ideas to address mobile populations' needs were elicited. After refinement, these intervention options were presented to the same communities for prioritization the following year, using a participatory ranking approach. RESULTS: Transit hubs, trading centers, and beach sites were identified as desirable service locations. Communities prioritized mobile health 'cards' with electronic medical records and peer-delivered home-based services. Mobile health clinics, longer antiretroviral refills, and 24/7 (after service) were less desirable options. Care challenges included: lack of transfer letters to other clinics; inability to adhere to scheduled appointments, medication regimens, and monitoring of treatment outcomes while mobile amongst others. CONCLUSIONS: Iterative discussions with mobile community stakeholders elicited communities' health priorities and identified challenges to achieving HIV care cascade outcomes. Understanding the mobility patterns and unique needs of mobile populations through responsive community engagement is critical.

RESUMO

Bacterial vaginosis (BV) is a proinflammatory genital condition characterized by high vaginal bacterial diversity and a paucity of Lactobacillus species. BV has been linked to an elevated risk of HIV acquisition among HIV-negative women and of forward HIV transmission to male sex partners among women living with HIV (adjusted hazard ratios of 1.69 and 3.17, respectively), potentially by eliciting genital inflammation in women with BV and their male sex partners. BV is also highly prevalent among women in sub-Saharan Africa, suggesting that BV treatment may have potential as an HIV prevention strategy. BV is typically treated with antibiotics but recurrence rates are high, possibly because treatment does not directly promote Lactobacillus growth. More recently, BV treatment strategies incorporating live biotherapeutic lactobacilli have led to sustained optimization of the vaginal microbiome and a decrease in inflammatory biomarkers previously associated with HIV susceptibility. Future studies are urgently needed to evaluate BV treatment strategies that can optimize the vaginal microbiome in the long term through colonization with H2 O2 -producing vaginal lactobacilli and to assess whether vaginal microbiota optimization is able to reduce the risk of HIV transmission.

RESUMO

PURPOSE: Respondent-driven sampling (RDS) uses long-chain referral whereby members of the target population recruit other members. We describe the use of RDS for a mixed-methods sexual and reproductive health (SRH) study in Kisumu, Kenya. METHODS: Initial seeds for the cross-sectional surveys were selected from adolescents aged 15-19 residing in urban informal settlements. Participants were provided up to five referral coupons to distribute. RESULTS: Across four communities, 18 seeds were selected, 13,489 coupons distributed, and 3381 adolescents referred, yielding a 25% coupon return rate. We enrolled 3061 participants for a 23% survey rate. Median referral lag time was three days (IQR 1, 7). Demographic characteristics reached equilibrium between recruitment waves 5 to 8 in three communities, and waves 7 to 15 in the fourth. CONCLUSIONS: Our study demonstrated that RDS is a feasible and efficient approach for recruiting a large sample of adolescents. Though our research focused on SRH, many adolescents residing in the impoverished urban environments where our study was implemented also experience food insecurity, housing instability and violence. RDS can therefore be a valuable recruitment approach for future studies to reach vulnerable adolescents and design interventions that address the variety of health-related challenges that affect this underserved population.
