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

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

BACKGROUND: Bacterial vaginosis affects 15 to 50% of women of reproductive age, and recurrence is common after treatment with an antibiotic agent. The high incidence of recurrence suggests the need for new treatments to prevent recurrent bacterial vaginosis. METHODS: We conducted a randomized, double-blind, placebo-controlled, phase 2b trial to evaluate the ability of Lactobacillus crispatus CTV-05 (Lactin-V) to prevent the recurrence of bacterial vaginosis. Women 18 to 45 years of age who had received a diagnosis of bacterial vaginosis and who had completed a course of vaginal metronidazole gel as part of the eligibility requirements were randomly assigned, in a 2:1 ratio, to receive vaginally administered Lactin-V or placebo for 11 weeks; follow-up occurred through week 24. The primary outcome was the percentage of women who had a recurrence of bacterial vaginosis by week 12. RESULTS: A total of 228 women underwent randomization: 152 to the Lactin-V group and 76 to the placebo group; of these participants, 88% in the Lactin-V group and 84% in the placebo group could be evaluated for the primary outcome. In the intention-to-treat population, recurrence of bacterial vaginosis by week 12 occurred in 46 participants (30%) in the Lactin-V group and in 34 participants (45%) in the placebo group (risk ratio after multiple imputation for missing responses, 0.66; 95% confidence interval [CI], 0.44 to 0.87; P = 0.01). The risk ratio for recurrence by week 24 (also calculated with multiple imputation for missing responses) was 0.73 (95% CI, 0.54 to 0.92). At the 12-week visit, L. crispatus CTV-05 was detected in 79% of participants in the Lactin-V group. The percentage of participants who had at least one adverse event related to Lactin-V or placebo by week 24 did not differ significantly between the groups. The percentage of participants with local or systemic adverse events was similar in the two groups. CONCLUSIONS: The use of Lactin-V after treatment with vaginal metronidazole resulted in a significantly lower incidence of recurrence of bacterial vaginosis than placebo at 12 weeks.

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

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

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

Little is known about the association of gender-based power imbalances and health and health behaviors among women with HIV (WWH). We examined cross-sectional baseline data among WWH in a cluster-randomized control trial (NCT02815579) in rural Kenya. We assessed associations between the Sexual Relationship Power Scale (SRPS) and ART adherence, physical and mental health, adjusting for sociodemographic and social factors. SRPS consists of two subscales: relationship control (RC) and decision-making dominance. Women in the highest and middle tertiles for RC had a 7.49 point and 8.88 point greater Medical Outcomes Study-HIV mental health score, and a 0.27 and 0.29 lower odds of depression, respectively, compared to women in the lowest tertile. We did not find associations between SPRS or its subscales and ART adherence. Low sexual relationship power, specifically low RC, may be associated with poor mental health among WWH. Intervention studies aimed to improve RC among WWH should be studied to determine their effect on improving mental health.


RESUMEN: Poco se sabe acerca de su asociación con los desequilibrios de poder basados en el género y los comportamientos de salud y salud entre las mujeres con Virus de Inmunodeficiencia Humana (VIH). Examinamos los datos de referencia transversales entre mujeres con VIH en un ensayo de control aleatorizado por grupos (NCT02815579) en las zonas rurales de Kenia. Evaluamos las asociaciones entre la Escala de Poder de Relación Sexual y la adherencia a la Terapia Antirretroviral (TAR), la salud física y mental, ajustando por factores sociodemográficos y sociales. La Escala de Poder de Relación Sexual consiste de dos subescalas: control de relaciones y dominio en la toma de decisiones. Las mujeres en los terciles más alto y mediano para control de relaciones tenían una puntuación de salud mental de 7.49 puntos y 8.88 puntos mayor en el Medical Outcomes Study HIV Health Survey (MOS)-HIV, y una puntuación de salud mental de 0.27 y 0.29 menores probabilidades de depresión, respectivamente, en comparación con las mujeres en el tercil más bajo. El bajo poder de relación sexual, específicamente el control de relaciones bajo, puede estar asociado con una salud mental deficiente entre las mujeres con VIH. Se deben estudiar estudios de intervención destinados a mejorar el control de relaciones entre mujeres con VIH para determinar su efecto en mejorar la salud mental.

RESUMO

Population mobility is associated with higher-risk sexual behaviors in sub-Saharan Africa and is a key driver of the HIV epidemic. We conducted a longitudinal cohort study to estimate associations between recent mobility (overnight travel away from home in past six months) or migration (changes of residence over defined geopolitical boundaries) and higher-risk sexual behavior among co-resident couples (240 couples aged ≥ 16) from 12 rural communities in Kenya and Uganda. Data on concurrent mobility and sexual risk behaviors were collected every 6-months between 2015 and 2020. We used sex-pooled and sex-stratified multilevel models to estimate associations between couple mobility configurations (neither partner mobile, male mobile/female not mobile, female mobile/male not mobile, both mobile) and the odds of higher-risk (casual, commercial sex worker/client, one night stand, inherited partner, stranger) and concurrent sexual partnerships based on who was mobile. On average across all time points and subjects, mobile women were more likely than non-mobile women to have a higher-risk partner; similarly, mobile men were more likely than non-mobile men to report a higher-risk partnership. Men with work-related mobility versus not had higher odds of higher-risk partnerships. Women with work-related mobility versus not had higher odds of higher-risk partnerships. Couples where both members were mobile versus neither had greater odds of higher-risk partnerships. In analyses using 6-month lagged versions of key predictors, migration events of men, but not women, preceded higher-risk partnerships. Findings demonstrate HIV risks for men and women associated with mobility and the need for prevention approaches attentive to the risk-enhancing contexts of mobility.

RESUMO

Few studies have explored land access, a structural driver of health, and women's participation in livelihood interventions to improve food security and HIV outcomes. This qualitative study, embedded within Shamba Maisha (NCT02815579)-a randomized controlled trial (RCT) examining the impact of a multisectoral intervention among farmers living with HIV in western Kenya-sought to explore the influence of perceived access to and control of land on agricultural productivity, investments, and benefits. Thirty in-depth interviews (IDIs) were conducted with purposively sampled men and women, 3 to 6 months after receiving intervention inputs; data were deductively and inductively coded and analyzed. Farming practices and participation in Shamba Maisha were dependent on land tenure and participants' perceived strength of claim over their land, with participants who perceived themselves to be land insecure less likely to make long-term agricultural investments. Land tenure was influenced by a number of factors and posed unique challenges for women which negatively impacted uptake and success in the intervention. Data underscore the importance of secure land tenure for the success of similar interventions, especially for women; future interventions should integrate land security programming for improved outcomes for all.

RESUMO

BACKGROUND: Universal antiretroviral therapy (ART) with annual population testing and a multidisease, patient-centered strategy could reduce new human immunodeficiency virus (HIV) infections and improve community health. METHODS: We randomly assigned 32 rural communities in Uganda and Kenya to baseline HIV and multidisease testing and national guideline-restricted ART (control group) or to baseline testing plus annual testing, eligibility for universal ART, and patient-centered care (intervention group). The primary end point was the cumulative incidence of HIV infection at 3 years. Secondary end points included viral suppression, death, tuberculosis, hypertension control, and the change in the annual incidence of HIV infection (which was evaluated in the intervention group only). RESULTS: A total of 150,395 persons were included in the analyses. Population-level viral suppression among 15,399 HIV-infected persons was 42% at baseline and was higher in the intervention group than in the control group at 3 years (79% vs. 68%; relative prevalence, 1.15; 95% confidence interval [CI], 1.11 to 1.20). The annual incidence of HIV infection in the intervention group decreased by 32% over 3 years (from 0.43 to 0.31 cases per 100 person-years; relative rate, 0.68; 95% CI, 0.56 to 0.84). However, the 3-year cumulative incidence (704 incident HIV infections) did not differ significantly between the intervention group and the control group (0.77% and 0.81%, respectively; relative risk, 0.95; 95% CI, 0.77 to 1.17). Among HIV-infected persons, the risk of death by year 3 was 3% in the intervention group and 4% in the control group (0.99 vs. 1.29 deaths per 100 person-years; relative risk, 0.77; 95% CI, 0.64 to 0.93). The risk of HIV-associated tuberculosis or death by year 3 among HIV-infected persons was 4% in the intervention group and 5% in the control group (1.19 vs. 1.50 events per 100 person-years; relative risk, 0.79; 95% CI, 0.67 to 0.94). At 3 years, 47% of adults with hypertension in the intervention group and 37% in the control group had hypertension control (relative prevalence, 1.26; 95% CI, 1.15 to 1.39). CONCLUSIONS: Universal HIV treatment did not result in a significantly lower incidence of HIV infection than standard care, probably owing to the availability of comprehensive baseline HIV testing and the rapid expansion of ART eligibility in the control group.

RESUMO

Youth aged 15-24 years comprise 48% of new HIV infections and 15% of persons living with HIV in Kisumu County, Kenya. We assessed factors associated with HIV infection among youth participating in the Community Health Initiative (CHI) implemented in an urban informal settlement in 2018. Predictors of HIV infection were assessed by multivariable logistic regression. CHI engaged 4,441 youth through community health campaigns and home-based HIV testing. HIV prevalence was 3.5% overall and 7.1% among young women aged 20-24. There were 24 youth newly identified as HIV-positive out of 157 total HIV-positive youth. HIV-positive status was positively associated with being female (aOR = 2.46; 95% CI 1.57, 3.84) and aged 20-24 (aOR = 2.40; 95% CI 1.52, 3.79), and inversely associated with secondary school education or higher (aOR = 0.27; 95% CI 0.16, 0.44). Our findings highlight the need for HIV prevention programs specially tailored for youth to further reduce new HIV infections in this priority population.

RESUMO

Reliable access to safe and acceptable water in sufficient quantities (i.e., water security) is important for medication adherence and limiting pathogen exposure, yet prior studies have only considered the role of food security as a social determinant of HIV-related health. Therefore, the objective of this analysis was to assess the relationships between household water insecurity and HIV-related outcomes among adults living with HIV in western Kenya (N = 716). We conducted a cross-sectional analysis of baseline data from Shamba Maisha (NCT02815579), a cluster randomized controlled trial of a multisectoral agricultural and asset loan intervention. Baseline data were collected from June 2016 to December 2017. We assessed associations between water insecurity and HIV-related outcomes, adjusting for clinical and behavioral confounders, including food insecurity. Each five-unit higher household water insecurity score (range: 0-51) was associated with 1.21 higher odds of having a viral load ≥ 1000 copies/mL (95% CI 1.07, 1.36) and 1.26 higher odds of AIDS-defining illness (95% CI 1.11, 1.42). Household water insecurity was not associated with CD4 cell count (B: 0.27; 95% CI -3.59, 13.05). HIV treatment and support programs should consider assessing and addressing water insecurity in addition to food insecurity to optimize HIV outcomes.


RESUMEN: El acceso seguro al agua potable en cantidades suficientes (es decir, seguridad hídrica) es importante para la adherencia a la medicación y para limitar la exposición a patógenos; sin embargo, estudios anteriores solo han considerado el papel de la seguridad alimentaria como un determinante social de salud relacionado con el VIH. Por lo tanto, el objetivo de este análisis fue evaluar las relaciones entre la inseguridad hídrica en hogares y los resultados relacionados con el VIH en adultos que viven con VIH en el oeste de Kenia (N = 716). Realizamos un análisis transversal de los datos basales de la iniciativa Shamba Maisha (NCT02815579), un ensayo controlado aleatorio por conglomerados de una intervención multisectorial de créditos para insumos agrícolas. Los datos basales se recopilaron de junio de 2016 a diciembre de 2017. Evaluamos las asociaciones entre la inseguridad hídrica y resultados relacionados con el VIH, ajustando por factores de confusión clínicos y conductuales, incluyendo inseguridad alimentaria. Cada cinco unidades superiores de puntajes de inseguridad hídrica doméstica (rango: 0-51) fue asociado con 1.21 mayores probabilidades de tener una carga viral más alta ≥ 1000 copias / ml (CI 95%: 1,07-1,36) y con 1.26 mayores probabilidades de factores determinantes del SIDA (CI 95%: 1,11-1,42). La inseguridad de hídrica doméstica no se asoció con el recuento de células CD4 (B: −0,27; CI 95%: -13,59-13,05). Los programas de tratamiento y de apoyo al VIH deben considerar evaluar y abordar la inseguridad hídrica además de la inseguridad alimentaria para optimizar los resultados del VIH.

RESUMO

Pediatric HIV remains a significant global concern, with 160,000 new infections annually. Accelerating Children's HIV/AIDS Treatment (ACT) provided a strategic response to the "treatment gap" for children. We examined whether activities under ACT increased testing and identification of youth living with HIV (YLWH). Family AIDS Care & Education Services implemented ACT across 130 health facilities in western Kenya between October 2015 and September 2016, providing: HIV-testing counselors and space; training on the Family Information Table (FIT) and chart audits; community outreach testing; and text message reminders for pregnant women. We analyzed the number of youths tested and identified with HIV over time and between intervention and control sites using interrupted time series analysis. We tested 268,312 youths (7,183 infants <18 months; 145,833 children 18 months to 9 years; and 115,296 adolescents 10-14 years). Mean monthly number tested per health facility increased from 2.8 to 7.2 (p < 0.0001) in infants, 44.8-142.0 (p < 0.0001) in children, and 30.1-123.3 (p < 0.0001) in adolescents. Mean monthly number identified with HIV per facility increased from 0.06 to 0.37 (p < 0.0001) in infants; 0.34-0.62 (p = 0.008) in children; and 0.17-0.26 (p = 0.04) in adolescents, resulting in 1,328 diagnoses. Among infants, FIT training was associated with increased HIV testing over time, incidence rate ratio (IRR) = 3.85 (95% confidence interval [CI] 2.16-6.84; p < 0.0001). Text messaging increased testing, IRR = 2.10 (95% CI 1.57-2.80; p < 0.0001) and identification of HIV in infants, IRR = 1.83 (95% CI 1.06-3.18; p = 0.0381) and older children, IRR = 2.25 (95% CI 1.62, 3.13; p < 0.0001). Chart audits increased testing over time among adolescents (IRR = 2.11; 95% CI 1.21-3.66; p = 0.0082). Outreach was associated with identification of adolescents with HIV, IRR = 1.58 (95% CI 1.22-2.06; p = 0.0005). In lower-income settings, targeted interventions effective at reaching YLWH can help optimize resource allocation to address gaps in testing and identification to further reduce HIV-related morbidity and mortality.

RESUMO

INTRODUCTION: Despite the increased risk of cervical cancer among HIV-positive women, many HIV-care programs do not offer integrated cervical cancer screening. Incorporating self-collected Human Papillomavirus (HPV) testing into HIV programs is a potential strategy to identify women at higher risk for cervical cancer while leveraging the staffing, infrastructure and referral systems for existing services. Community-based HIV and HPV testing has been effective and efficient when offered in single-disease settings. METHODS: This cross-sectional study was conducted within a community outreach and multi-disease screening campaigns organized by the Family AIDS Care and Education Services in Kisumu County, Kenya. In addition to HIV testing, the campaigns provided screening for TB, malaria, hypertension, diabetes, and referrals for voluntary medical male circumcision. After these services, women aged 25-65 were offered self-collected HPV testing. Rates and predictors of cervical cancer screening uptake and of HPV positivity were analyzed using tabular analysis and Fisher's Exact Test. Logistic regression was performed to explore multivariate associations with screening uptake. RESULTS: Among the 2016 women of screening age who attended the outreach campaigns, 749 women (35.6%) were screened, and 134 women (18.7%) were HPV-positive. In bivariate analysis, women who had no children (p < 0.01), who were not pregnant (p < 0.01), who were using contraceptives (p < 0.01), who had sex without using condoms (p < 0.05), and who were encouraged by a family member other than their spouse (p < 0.01), were more likely to undergo screening. On multivariable analysis, characteristics associated with higher screening uptake included: women aged 45-54 (OR 1.62, 95% CI 1.05-2.52) compared to women aged 25-34; no children (OR 1.65, 95% CI 1.06-2.56); and family support other than their spouse (OR 1.53, 95% CI 1.09-2.16). Women who were pregnant were 0.44 times (95% CI 0.25-0.76) less likely to get screened. Bivariate analyses with participant characteristics and HPV positivity found that women who screened HPV-positive were more likely to be HIV-positive (p < 0.001) and single (p < 0.001). CONCLUSIONS: The low screening uptake may be attributed to implementation challenges including long waiting times for service at the campaign and delays in procuring HPV test kits. However, given the potential benefits of integrating HPV testing into HIV outreach campaigns, these challenges should be examined to develop more effective multi-disease outreach interventions.

RESUMO

A Lactobacillus-dominated vaginal microbiota (VMB) has been associated with health and considered an important host defense mechanism against urogenital infections. Conversely, depletion of lactobacilli and increased microbial diversity, amplifies the risk of adverse gynecologic and obstetric outcomes. A common clinical condition that exemplifies dysbiosis is bacterial vaginosis (BV). BV is currently treated with antibiotics, but frequently recurs, due in part to persistent dysbiosis and failure of lactobacilli to repopulate the vagina. New treatment options are needed to address BV. The VMB is relatively simple and optimally dominated by one or several species of Lactobacillus. Lactobacillus crispatus is strongly associated with vaginal health and depleted in dysbiosis. Replenishing the dysbiotic VMB with protective L. crispatus CTV-05 is a promising approach to prevent recurrent infections and improve women's health. Here we discuss confirmation of this approach with the microbiome-based biologic drug, LACTIN-V (L. crispatus CTV-05), focusing on prevention of BV recurrence.

RESUMO

Pelvic inflammatory disease (PID) is a clinical syndrome that has been associated with a wide range of potential causal pathogens. Three broad groups of organisms have been isolated from the genital tract of people with PID: sexually transmitted organisms such as Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, and Trichomonas vaginalis; bacterial vaginosis (BV)-associated species and genera such as Atopobium vaginae, Sneathia, and Megasphaera; and genera and species usually associated with the gastrointestinal or respiratory tracts such as Bacteroides, Escherichia coli, Streptococcus, or Haemophilus influenza. Although PID is often considered to be synonymous with gonorrhea or chlamydia, these pathogens are found in only one quarter to one third of people with PID, suggesting that broader screening and diagnostic and treatment strategies need to be considered to reduce the burden of PID and its associated sequelae.

RESUMO

BACKGROUND: We tested the hypothesis that patient-centered, streamlined human immunodeficiency virus (HIV) care would achieve lower mortality than the standard treatment model for persons with HIV and CD4 ≤ 350/uL in the setting of population-wide HIV testing. METHODS: In the SEARCH (Sustainable East Africa Research in Community Health) Study (NCT01864603), 32 communities in rural Uganda and Kenya were randomized to country-guided antiretroviral therapy (ART) versus streamlined ART care that included rapid ART start, visit spacing, flexible clinic hours, and welcoming environment. We assessed persons with HIV and CD4 ≤ 350/uL, ART eligible in both arms, and estimated the effect of streamlined care on ART initiation and mortality at 3 years. Comparisons between study arms used a cluster-level analysis with survival estimates from Kaplan-Meier; estimates of ART start among ART-naive persons treated death as a competing risk. RESULTS: Among 13 266 adults with HIV, 2973 (22.4%) had CD4 ≤ 350/uL. Of these, 33% were new diagnoses, and 10% were diagnosed but ART-naive. Men with HIV were almost twice as likely as women with HIV to have CD4 ≤ 350/uL and be untreated (15% vs 8%, respectively). Streamlined care reduced mortality by 28% versus control (risk ratio [RR] = 0.72; 95% confidence interval [CI]: .56, .93; P = .02). Despite eligibility in both arms, persons with CD4 ≤ 350/uL started ART faster under streamlined care versus control (76% vs 43% by 12 months, respectively; P < .001). Mortality was reduced substantially more among men (RR = 0.61; 95% CI: .43, .86; P = .01) than among women (RR = 0.90; 95% CI: .62, 1.32; P = .58). CONCLUSIONS: After population-based HIV testing, streamlined care reduced population-level mortality among persons with HIV and CD4 ≤ 350/uL, particularly among men. Streamlined HIV care models may play a key role in global efforts to reduce AIDS deaths.

RESUMO

BACKGROUND: HIV-positive women suffer a high burden of mental disorders due in part to gender-based violence (GBV). Comorbid depression and posttraumatic stress disorder (PTSD) are typical psychiatric consequences of GBV. Despite attention to the HIV-GBV syndemic, few HIV clinics offer formal mental healthcare. This problem is acute in sub-Saharan Africa, where the world's majority of HIV-positive women live and prevalence of GBV is high. METHODS AND FINDINGS: We conducted a randomized controlled trial at an HIV clinic in Kisumu, Kenya. GBV-affected HIV-positive women with both major depressive disorder (MDD) and PTSD were randomized to 12 sessions of interpersonal psychotherapy (IPT) plus treatment as usual (TAU) or Wait List+TAU. Nonspecialists were trained to deliver IPT inside the clinic. After 3 months, participants were reassessed, and those assigned to Wait List+TAU were given IPT. The primary outcomes were diagnosis of MDD and PTSD (Mini International Neuropsychiatric Interview) at 3 months. Secondary outcomes included symptom measures of depression and PTSD, intimate partner violence (IPV), and disability. A total of 256 participants enrolled between May 2015 and July 2016. At baseline, the mean age of the women in this study was 37 years; 61% reported physical IPV in the past week; 91% reported 2 or more lifetime traumatic events and monthly income was 18USD. Multilevel mixed-effects logistic regression showed that participants randomized to IPT+TAU had lower odds of MDD (odds ratio [OR] 0.26, 95% CI [0.11 to 0.60], p = 0.002) and lower odds of PTSD (OR 0.35, [0.14 to 0.86], p = 0.02) than controls. IPT+TAU participants had lower odds of MDD-PTSD comorbidity than controls (OR 0.36, 95% CI [0.15 to 0.90], p = 0.03). Linear mixed models were used to assess secondary outcomes: IPT+TAU participants had reduced disability (-6.9 [-12.2, -1.5], p = 0.01), and nonsignificantly reduced work absenteeism (-3.35 [-6.83, 0.14], p = 0.06); partnered IPT+TAU participants had a reduction of IPV (-2.79 [-5.42, -0.16], p = 0.04). Gains were maintained across 6-month follow-up. Treatment group differences were observed only at month 3, the time point at which the groups differed in IPT status (before cross over). Study limitations included 35% attrition inclusive of follow-up assessments, generalizability to populations not in HIV care, and data not collected on TAU resources accessed. CONCLUSIONS: IPT for MDD and PTSD delivered by nonspecialists in the context of HIV care yielded significant improvements in HIV-positive women's mental health, functioning, and GBV (IPV) exposure, compared to controls.

RESUMO

BACKGROUND: Hypertension treatment reduces morbidity and mortality yet has not been broadly implemented in many low-resource settings, including sub-Saharan Africa (SSA). We hypothesized that a patient-centered integrated chronic disease model that included hypertension treatment and leveraged the HIV care system would reduce mortality among adults with uncontrolled hypertension in rural Kenya and Uganda. METHODS AND FINDINGS: This is a secondary analysis of the SEARCH trial (NCT:01864603), in which 32 communities underwent baseline population-based multidisease testing, including hypertension screening, and were randomized to standard country-guided treatment or to a patient-centered integrated chronic care model including treatment for hypertension, diabetes, and HIV. Patient-centered care included on-site introduction to clinic staff at screening, nursing triage to expedite visits, reduced visit frequency, flexible clinic hours, and a welcoming clinic environment. The analytic population included nonpregnant adults (≥18 years) with baseline uncontrolled hypertension (blood pressure ≥140/90 mm Hg). The primary outcome was 3-year all-cause mortality with comprehensive population-level assessment. Secondary outcomes included hypertension control assessed at a population level at year 3 (defined per country guidelines as at least 1 blood pressure measure <140/90 mm Hg on 3 repeated measures). Between-arm comparisons used cluster-level targeted maximum likelihood estimation. Among 86,078 adults screened at study baseline (June 2013 to July 2014), 10,928 (13%) had uncontrolled hypertension. Median age was 53 years (25th to 75th percentile 40 to 66); 6,058 (55%) were female; 677 (6%) were HIV infected; and 477 (4%) had diabetes mellitus. Overall, 174 participants (3.2%) in the intervention group and 225 participants (4.1%) in the control group died during 3 years of follow-up (adjusted relative risk (aRR) 0.79, 95% confidence interval (CI) 0.64 to 0.97, p = 0.028). Among those with baseline grade 3 hypertension (≥180/110 mm Hg), 22 (4.9%) in the intervention group and 42 (7.9%) in the control group died during 3 years of follow-up (aRR 0.62, 95% CI 0.39 to 0.97, p = 0.038). Estimated population-level hypertension control at year 3 was 53% in intervention and 44% in control communities (aRR 1.22, 95% CI 1.12 to 1.33, p < 0.001). Study limitations include inability to identify specific causes of death and control conditions that exceeded current standard hypertension care. CONCLUSIONS: In this cluster randomized comparison where both arms received population-level hypertension screening, implementation of a patient-centered hypertension care model was associated with a 21% reduction in all-cause mortality and a 22% improvement in hypertension control compared to standard care among adults with baseline uncontrolled hypertension. Patient-centered chronic care programs for HIV can be leveraged to reduce the overall burden of cardiovascular mortality in SSA. TRIAL REGISTRATION: ClinicalTrials.gov NCT01864603.

RESUMO

BACKGROUND: Oral pre-exposure prophylaxis (PrEP) is highly effective for HIV prevention, but data are limited on HIV incidence among PrEP users in generalized epidemic settings, particularly outside of selected risk groups. We performed a population-based PrEP study in rural Kenya and Uganda and sought to evaluate both changes in HIV incidence and clinical and virologic outcomes following seroconversion on PrEP. METHODS AND FINDINGS: During population-level HIV testing of individuals ≥15 years in 16 communities in the Sustainable East Africa Research in Community Health (SEARCH) study (NCT01864603), we offered universal access to PrEP with enhanced counseling for persons at elevated HIV risk (based on serodifferent partnership, machine learning-based risk score, or self-identified HIV risk). We offered rapid or same-day PrEP initiation and flexible service delivery with follow-up visits at facilities or community-based sites at 4, 12, and every 12 weeks up to week 144. Among participants with incident HIV infection after PrEP initiation, we offered same-day antiretroviral therapy (ART) initiation and analyzed HIV RNA, tenofovir hair concentrations, drug resistance, and viral suppression (<1,000 c/ml based on available assays) after ART start. Using Poisson regression with cluster-robust standard errors, we compared HIV incidence among PrEP initiators to incidence among propensity score-matched recent historical controls (from the year before PrEP availability) in 8 of the 16 communities, adjusted for risk group. Among 74,541 individuals who tested negative for HIV, 15,632/74,541 (21%) were assessed to be at elevated HIV risk; 5,447/15,632 (35%) initiated PrEP (49% female; 29% 15-24 years; 19% in serodifferent partnerships), of whom 79% engaged in ≥1 follow-up visit and 61% self-reported PrEP adherence at ≥1 visit. Over 7,150 person-years of follow-up, HIV incidence was 0.35 per 100 person-years (95% confidence interval [CI] 0.22-0.49) among PrEP initiators. Among matched controls, HIV incidence was 0.92 per 100 person-years (95% CI 0.49-1.41), corresponding to 74% lower incidence among PrEP initiators compared to matched controls (adjusted incidence rate ratio [aIRR] 0.26, 95% CI 0.09-0.75; p = 0.013). Among women, HIV incidence was 76% lower among PrEP initiators versus matched controls (aIRR 0.24, 95% CI 0.07-0.79; p = 0.019); among men, HIV incidence was 40% lower, but not significantly so (aIRR 0.60, 95% CI 0.12-3.05; p = 0.54). Of 25 participants with incident HIV infection (68% women), 7/25 (28%) reported taking PrEP ≤30 days before HIV diagnosis, and 24/25 (96%) started ART. Of those with repeat HIV RNA after ART start, 18/19 (95%) had <1,000 c/ml. One participant with viral non-suppression was found to have transmitted viral resistance, as well as emtricitabine resistance possibly related to PrEP use. Limitations include the lack of contemporaneous controls to assess HIV incidence without PrEP and that plasma samples were not archived to assess for baseline acute infection. CONCLUSIONS: Population-level offer of PrEP with rapid start and flexible service delivery was associated with 74% lower HIV incidence among PrEP initiators compared to matched recent controls prior to PrEP availability. HIV infections were significantly lower among women who started PrEP. Universal HIV testing with linkage to treatment and prevention, including PrEP, is a promising approach to accelerate reductions in new infections in generalized epidemic settings.
