RESUMO

Women's ability to control their fertility and have the number of children they want when they want them is an internationally recognized human right. This right has been the driving force behind family planning programs in low- and middle-income countries for more than five decades. The HIV epidemic added greater urgency to those efforts once the risk of vertical transmission of the virus from mothers to their infants was recognized. In 2013, we published a systematic review of the evidence of effectiveness of family planning counseling for women living with HIV, emphasizing HIV related behaviors. In this updated review, we examined 23 studies, primarily from sub-Saharan Africa. The evidence we uncovered reflected efforts to integrate services provided to women. These showed that providing contraceptive services, including intensified counseling and support, in the HIV clinics where women living with HIV received their care increased the likelihood of subsequent use of modern contraception by as much as fourfold. These studies reflected a greater focus on women's family planning decisions and behaviors and less focus on HIV-related behaviors. Among the possible causes of this noted difference we include the widespread coverage of antiretroviral treatment for HIV. This advance has apparently changed the rationale and the approach to integrating family planning and HIV services in ways that may not have been fully appreciated. The results, however, are beneficial: greater coverage of family planning for women who wish to control their fertility and a more equal partnership between family planning services and HIV services in pursuit of the mutual goal of providing integrated services to meet women's needs.

RESUMO

We conducted a systematic review and meta-analysis of the impact of needle and syringe exchange programs (NSP) on both individual- and community-level needle-sharing behaviors and other HIV-related outcomes in low- and middle-income countries (LMIC). A search of five databases for peer-reviewed trial or quasi-experimental studies reported through July 2021 identified 42 interventions delivered in 35 studies, with a total of 56,751 participants meeting inclusion criteria. Random-effects meta-analysis showed a significant protective association between NSP exposure and needle-sharing behaviors at the individual-level (odds ratio [OR] = 0.25, 95% confidence interval [CI] = 0.16-0.39, 8 trials, n = 3947) and community-level (OR 0.39, CI 0.22-0.69, 12 trials, n = 6850), although with significant heterogeneity. When stratified by needle-sharing directionality, NSP exposure remained associated with reduced receptive sharing, but not distributive sharing. NSP exposure was also associated with reduced HIV incidence and increased HIV testing but there were no consistent associations with prevalence of bloodborne infections. Current evidence suggests positive impacts of NSPs in LMICs.


RESUMEN: Realizamos una revisión sistemática y un metanálisis del impacto de los programas de intercambio de agujas y jeringas (NSP, por sus siglas en inglés) de los comportamientos de uso compartido de agujas tanto a nivel individual como comunitario y otros resultados relacionados con el VIH en países de ingresos bajos y medianos (LMIC, por sus siglas en inglés). Realizamos búsquedas sistemáticas en cinco bases de datos hasta julio de 2021 en busca de ensayos revisados por pares o estudios cuasiexperimentales. En general, 42 intervenciones informadas en 35 estudios entre 56 751 participantes cumplieron los criterios de inclusión. El metanálisis de efectos aleatorios de ocho estudios a nivel individual y 12 a nivel comunitario con 11 075 participantes en total mostró una asociación protectora significativa entre la exposición a NSP y los comportamientos de compartir agujas (individual: OR 0,25, IC95%: 0,16­0,39; comunidad: OR 0,39, IC95%:0,22­0,69), aunque con una heterogeneidad importante. Cuando se estratificó por la direccionalidad del intercambio de agujas, la exposición a NSP permaneció asociada con un intercambio receptivo reducido, pero no con un intercambio distributivo. La exposición a NSP también se asoció con una incidencia reducida del VIH y un aumento de las pruebas del VIH, pero no hubo asociaciones consistentes para la prevalencia de infecciones transmitidas por la sangre. La evidencia actual sugiere impactos positivos de los NSP en los LMIC.

RESUMO

Adolescent girls and young women (AGYW) are disproportionately affected by HIV, and oral pre-exposure prophylaxis (PrEP) can reduce HIV acquisition. The purpose of this scoping review was to synthesize results from interventions along the PrEP continuum for AGYW to inform research and programs. We searched electronic databases for studies published between January 2012-July 2021 and conducted secondary reference searching. Studies were included if they assessed interventions to increase PrEP interest, uptake, or continuation among AGYW. Results were synthesized narratively. Of 2168 citations identified, 50 studies were eligible for inclusion, and 20 contained AGYW-specific data. Among cisgender and transgender AGYW, studies overall demonstrated a positive impact on PrEP interest and uptake but generally attained suboptimal continuation rates. Results demonstrate feasibility of deploying PrEP across diverse settings-particularly when interventions are layered, tailored to AGYW, and include differentiated delivery-but also highlight knowledge gaps and the need for more holistic metrics of success.


RESUMEN: Las adolescentes y las mujeres jóvenes se ven afectadas de forma desproporcionada por el VIH, y la Profilaxis Pre-Exposición oral (PrEP) puede reducir la adquisición del VIH. El propósito de esta revisión de alcance fue sintetizar los resultados de las intervenciones a lo largo del continuo de la PrEP para las adolescentes y las mujeres jóvenes con el fin de informar la investigación y los programas. Se realizaron búsquedas en bases de datos electrónicas de estudios publicados entre enero 2012 a julio 2021 y se llevó a cabo una búsqueda secundaria de referencias. Los estudios se incluyeron si evaluaban intervenciones para aumentar el interés, la iniciación, o la continuación de la PrEP entre las adolescentes y las mujeres jóvenes. Los resultados se sintetizaron narrativamente. De las 2168 citas identificadas, 50 estudios fueron elegibles para inclusión y 20 contenían datos específicos de las adolescentes y las mujeres jóvenes. Entre las adolescentes y las mujeres jóvenes cisgénero y transgénero, los estudios demostraron un impacto positivo en el interés y la iniciación de la PrEP, pero en general alcanzaron tasas de continuación subóptimas. Los resultados demuestran la viabilidad del despliegue de la PrEP en diversos entornos­en particular cuando las intervenciones son estratificadas, se adaptan a las adolescentes y las mujeres jóvenes, e incluyen una prestación diferenciada­pero también destacan las lagunas de conocimiento y la necesidad de una métrica más holística del éxito.

RESUMO

Background. Across settings, individuals from populations that are multiply stigmatized are at increased risk of HIV and experience worse HIV treatment outcomes. As evidence expands on how intersecting stigmatized identities and conditions influence HIV outcomes, researchers have used diverse quantitative approaches to measure HIV-related intersectional stigma and discrimination. To date, no clear consensus exists regarding how to best quantitatively measure and analyze intersectional stigma and discrimination. Objectives. To review and document existing quantitative measures of HIV-related intersectional stigma and discrimination to inform research, programmatic, and policy efforts. Search Methods. We searched 5 electronic databases for relevant studies. References of included articles were screened for possible inclusion. Additional articles were screened on the basis of consultations with experts in the field. Selection Criteria. We included peer-reviewed studies published between January 1, 2010, and May 12, 2021, that were HIV related and presented 1 or more quantitative measures of stigma and discrimination using an intersectional lens in measure design or analysis. Data Collection and Analysis. Systematic methods were used to screen citations and abstract data via a standardized coding form. Data were analyzed by coding categories stratified according to 2 subgroups: (1) studies incorporating a single intersectional measure and (2) studies that examined intersectional stigma through analytical approaches combining multiple measures. Main Results. Sixteen articles met the inclusion criteria, 7 of which explicitly referenced intersectionality. Ten studies were from the United States. All of the studies included participants living with HIV. Among the 4 studies incorporating a single intersectional stigma measure, 3 explored race and gender stigma and 1 explored gender and HIV stigma. Studies involving analytic approaches (n = 12) mostly examined intersectional stigma via interaction terms in multivariate regression models. Three studies employed structural equation modeling to examine interactive effects or latent constructs of intersectional stigma. Conclusions. Research on the measurement of HIV-related intersectional stigma and discrimination is currently concentrated in high-income settings and generally focuses on the intersection of 2 identities (e.g., race and gender). Efforts are needed to expand appropriate application of intersectionality in the development, adaptation, and use of measures of HIV-related intersectional stigma and discrimination. The use of context-, identity-, or condition-adaptable measures should be considered. Researchers should also carefully consider how to meaningfully engage communities in the process of measurement development. Public Health Implications. The measures and analytic approaches presented could significantly enhance public health efforts in assessing the impact of HIV-related intersectional stigma and discrimination on critical health outcomes.

RESUMO

If sexual partner concurrency drives HIV transmission dynamics, shouldn't HIV prevention efforts be addressing this behavior? We systematically reviewed studies evaluating interventions to reduce sexual partner concurrency in low- and middle-income countries using pre/post or multi-arm designs. Only two studies met our inclusion criteria; neither found significant differences by intervention exposure on self-reported concurrency. Overall, very few interventions have specifically targeted concurrency, and those that did have not been rigorously evaluated. In practice, concurrency may be difficult to separate from multiple partnerships more generally.

RESUMO

Decentralization of HIV care across sub-Saharan Africa has increased access to anti-retroviral therapy (ART). Although traveling for care has traditionally been viewed as a barrier, some individuals may choose to travel for care due to stigma and fear of HIV status disclosure. We sought to understand the prevalence of traveling long distances for HIV care, as well as reasons for engaging in such travel. Using a concurrent embedded mixed-methods study design, individuals receiving care at two HIV care and treatment clinics in Tanzania completed a quantitative survey (n = 196), and a sub-set of participants reporting long-distance travel for care were interviewed (n = 31). Overall 58.2% of participants (n = 114/196) reported knowing of a closer clinic than the one they chose to attend. Having experienced enacted stigma was significantly associated with traveling for care (OR 2.31, 95% CI 1.12, 4.75, p = 0.02). Reasons for clinic choice centered on three main themes: clinic familiarity, quality of care, and stigma. Traveling for care was often viewed as an enabling strategy for remaining engaged in care by helping overcome other barriers, including stigma and suboptimal quality of care.

RESUMO

BACKGROUND: A substantial number of new HIV infections in sub-Saharan Africa occur within stable couples. Biomedical prevention (pre-exposure prophylaxis, PrEP) and treatment (antiretroviral therapy, ART) can provide benefits to sexual partners and can be used to prevent infection within HIV serodiscordant couples. However, research is typically focused on individuals, not dyads, even when the intervention may directly or indirectly impact sexual partners. Gaps remain in understanding best practices for recruitment, informed consent, and intervention implementation in studies involving HIV prevention and treatment among heterosexual serodiscordant couples. This qualitative study was undertaken to understand and describe decision-making and dyadic-level influence among members of serodiscordant couples regarding (1) participation in a dyadic-based research study involving HIV self-testing and access to PrEP, and (2) utilization of PrEP and ART. METHODS: This qualitative study was nested within an observational cohort study assessing the acceptability of home-based couples' HIV self-testing and uptake of dyadic care for serodiscordant couples involving facilitated referral for HIV-positive partners and access to PrEP for HIV-negative partners. Semi-structured in-depth interviews were conducted among a subset of study participants (n = 22) as well as individuals involved in serodiscordant relationships who chose not to participate (n = 9). Interviews focused on couples' decision-making regarding study participation and dyadic-level influence on medication use. Interviews were transcribed verbatim and translated from Kiswahili into English. Data were analyzed using thematic analysis. RESULTS: Three major themes were identified: (1) HIV as "two people's secret" and the elevated role of partner support in serodiscordant relationships; (2) the intersectional role of HIV-status and gender on decision-making; (3) the relational benefits of PrEP, including psychosocial benefits for the couple that extend beyond prevention. CONCLUSIONS: The study found that couples made joint decisions regarding study participation and uptake of HIV-related medication. Relational autonomy and dyadic-level influence should be considered within research and programs involving HIV serodiscordant couples.

RESUMO

Communication between sexual partners is an important component of HIV prevention and occurs within a broader context of socio-culturally defined gender norms and dynamics. We analyzed cross-sectional data from a community-based random sample of men and women living in Kisarawe, Tanzania to understand factors related to partner communication about HIV. Bivariate and multivariate logistic regression analyses, disaggregated by gender, included variables at the individual-, relational-, and community-levels. Individuals who knew their HIV-positive status prior to the study were excluded as the focus was on risk communication, not HIV status disclosure. Of 524 participants, 129 women (43.3%) and 96 men (42.5%) reported HIV-related communication with their most recent sexual partner. For women but not men, individual-level socioeconomic factors-including education, possession of a household radio, and employment-and relational-level factors-including partner age and type-were significantly associated with partner communication. At the community level, being socially engaged was positively correlated with partner communication across genders (aOR = 2.02, 95% CI 1.05-3.89, p = 0.03 for men and aOR = 1.74, 95% CI 1.03-2.95, p = 0.04 for women). For women, having less discriminatory attitudes toward people living with HIV and favorable perceived norms of HIV-related communication were significantly associated with partner communication. For men, agreeing that women should be allowed to work outside the home was significantly correlated with partner communication (aOR = 6.02, 95% CI 2.23-16.24, p < 0.001). Findings suggest a link between gender dynamics and partner communication, with individual and relational factors being associated with communication for women and community-level factors being associated with communication for both genders.

RESUMO

Capacity development is a process by which individuals, organizations and societies develop abilities to perform functions, solve problems and achieve objectives. This systematic review sought to document capacity development interventions, the associated outcomes and its effectiveness in increasing demand for rights and health services among key populations (KP) in low and middle-income countries. Twenty papers met our review's selection criteria. Significant improvements in health service utilization were achieved in most community mobilization and peer-led interventions. Whilst we found ample evidence linking capacity development to uptake of services, there was a striking dearth of research examining the impact of capacity development on demand for rights among KP. There was inadequate contextual data to explain variations in intervention effectiveness across different projects. More evidence is needed on the impact of capacity development on demand for health services and rights among KP. Consensus on parameters of capacity development and priority outcomes is required.

RESUMO

Daily oral pre-exposure prophylaxis (PrEP) is the use of antiretroviral drugs by HIV-negative people to prevent HIV infection. WHO released new guidelines in 2015 recommending PrEP for all populations at substantial risk of HIV infection. To prepare these guidelines, we conducted a systematic review of values and preferences among populations that might benefit from PrEP, women, heterosexual men, young women and adolescent girls, female sex workers, serodiscordant couples, transgender people and people who inject drugs, and among healthcare providers who may prescribe PrEP. A comprehensive search strategy reviewed three electronic databases of articles and HIV-related conference abstracts (January 1990-April 2015). Data abstraction used standardised forms to categorise by population groups and relevant themes. Of 3068 citations screened, 76 peer-reviewed articles and 28 conference abstracts were included. Geographic coverage was global. Most studies (N = 78) evaluated hypothetical use of PrEP, while 26 studies included individuals who actually took PrEP or placebo. Awareness of PrEP was low, but once participants were presented with information about PrEP, the majority said they would consider using it. Concerns about safety, side effects, cost and effectiveness were the most frequently cited barriers to use. There was little indication of risk compensation. Healthcare providers would consider prescribing PrEP, but need more information before doing so. Findings from a rapidly expanding evidence base suggest that the majority of populations most likely to benefit from PrEP feel positively towards it. These same populations would benefit from overcoming current implementation challenges with the shortest possible delay.

RESUMO

A community empowerment-based response to HIV is a process by which sex workers take collective ownership of programmes to achieve the most effective HIV outcomes and address social and structural barriers to their overall health and human rights. Community empowerment has increasingly gained recognition as a key approach for addressing HIV in sex workers, with its focus on addressing the broad context within which the heightened risk for infection takes places in these individuals. However, large-scale implementation of community empowerment-based approaches has been scarce. We undertook a comprehensive review of community empowerment approaches for addressing HIV in sex workers. Within this effort, we did a systematic review and meta-analysis of the effectiveness of community empowerment in sex workers in low-income and middle-income countries. We found that community empowerment-based approaches to addressing HIV among sex workers were significantly associated with reductions in HIV and other sexually transmitted infections, and with increases in consistent condom use with all clients. Despite the promise of a community-empowerment approach, we identified formidable structural barriers to implementation and scale-up at various levels. These barriers include regressive international discourses and funding constraints; national laws criminalising sex work; and intersecting social stigmas, discrimination, and violence. The evidence base for community empowerment in sex workers needs to be strengthened and diversified, including its role in aiding access to, and uptake of, combination interventions for HIV prevention. Furthermore, social and political change are needed regarding the recognition of sex work as work, both globally and locally, to encourage increased support for community empowerment responses to HIV.

RESUMO

The purpose of this study was to assess the effectiveness of behavioral counseling interventions in reducing sexual risk behaviors and HIV/STI prevalence in low- and middle-income countries. A systematic review of papers published between 1990 and 2011 was conducted, identifying studies that utilized either a multi-arm or pre-post design and presented post-intervention data. Standardized methods of searching and data abstraction were used, and 30 studies met inclusion criteria. Results are summarized by intervention groups: (a) people living with HIV; (b) people who use drugs and alcohol; (c) serodiscordant couples; (d) key populations for HIV prevention; and (e) people at low to moderate HIV risk. Evidence for the effectiveness of behavioral counseling was mixed, with more rigorously designed studies often showing modest or no effects. Recommendations about the use of behavioral counseling in developing countries are made based on study results and in light of the field's movement towards combination prevention programs.

RESUMO

When evaluating HIV prevention interventions, condom use is a common outcome measure used to assess changes in HIV-related behaviors; however, no widely accepted standards exist for its measurement. Using systematic review data on HIV prevention interventions conducted in low- and middle-income countries, we examined trends in condom use measurement since 1990. We abstracted data from standardized forms on six dimensions of condom use: partner type, temporal period, measurement scale, consistency, controlling for abstinence, and type of sex. Of 215 studies reviewed, 109 studies (51 %) measured condom use as a primary outcome. Outcomes were stratified by partner type in 47 studies (43 %). Assessing condom use at last sex was the most common measurement. Consistency of condom use was assessed in 47 studies (43 %). Developing and utilizing standards for condom use measurement would increase comparability of findings across studies and benefit HIV prevention research. Recommendations include measuring condom use at last sex, frequency of condom use, and number of protected sex acts in studies evaluating the efficacy of behavioral interventions on sexual risk behavior.

RESUMO

Income generation interventions, such as microfinance or vocational skills training, address structural factors associated with HIV risk. However, the effectiveness of these interventions on HIV-related outcomes in low- and middle-income countries has not been synthesized. The authors conducted a systematic review by searching electronic databases from 1990 to 2012, examining secondary references, and hand-searching key journals. Peer-reviewed studies were included in the analysis if they evaluated income generation interventions in low- or middle-income countries and provided pre-post or multi-arm measures on behavioral, psychological, social, care, or biological outcomes related to HIV prevention. Standardized forms were used to abstract study data in duplicate and study rigor was assessed. Of the 5218 unique citations identified, 12 studies met criteria for inclusion. Studies were geographically diverse, with six conducted in sub-Saharan Africa, three in South or Southeast Asia, and three in Latin America and the Caribbean. Target populations included adult women (N = 6), female sex workers/bar workers (N = 3), and youth/orphans (N = 3). All studies targeted females except two among youth/orphans. Study rigor was moderate, with two group-randomized trials and two individual-randomized trials. All interventions except three included some form of microfinance. Only a minority of studies found significant intervention effects on condom use, number of sexual partners, or other HIV-related behavioral outcomes; most studies showed no significant change, although some may have had inadequate statistical power. One trial showed a 55% reduction in intimate partner violence (adjusted risk ratio 0.45, 95% confidence interval 0.23-0.91). No studies measured incidence/prevalence of HIV or sexually transmitted infections among intervention recipients. The evidence that income generation interventions influence HIV-related behaviors and outcomes is inconclusive. However, these interventions may have important effects on outcomes beyond HIV prevention. Further studies examining not only HIV-related outcomes but also causal pathways and intermediate variables, are needed. Additional studies among men are also needed.

RESUMO

The Evidence Project conducts systematic reviews and meta-analyses of HIV behavioral interventions, behavioral aspects of biomedical interventions, combination prevention strategies, modes of service delivery, and integrated programs in low- and middle-income countries. Here, we present the overall protocol for our reviews. For each topic, we conduct a comprehensive search of five online databases, complemented by secondary reference searching. Articles are included if they are published in peer-reviewed journals and present pre/post or multi-arm data on outcomes of interest. Data are extracted from each included article by two trained coders working independently using standardized coding forms, with differences resolved by consensus. Risk of bias is assessed with the Evidence Project tool. Data are synthesized descriptively, and meta-analysis is conducted when there are similarly measured outcomes across studies. For over 20 years, this approach has allowed us to synthesize literature on the effectiveness of interventions and contribute to the global HIV response.

RESUMO

We conducted a systematic review and meta-analysis of community empowerment interventions for HIV prevention among sex workers in low- and middle-income countries from 1990-2010. Two coders abstracted data using standardized forms. Of 6,664 citations screened, ten studies met inclusion criteria. For HIV infection, two observational studies showed a significantly protective combined effect [odds ratio (OR): 0.84, 95% confidence interval (CI): 0.709-0.988]. For STI infection, one longitudinal study showed reduced gonorrhoea/chlamydia (OR: 0.51, 95% CI: 0.26-0.99). Observational studies showed reduced gonorrhoea (OR: 0.65, 95% CI: 0.47-0.90), but non-significant effects on chlamydia and syphilis. For condom use, one randomized controlled trial showed improvements with clients (beta: 0.3447, p = 0.002). One longitudinal study showed improvements with regular clients (OR: 1.9, 95% CI: 1.1-3.3), but no change with new clients. Observational studies showed improvements with new clients (OR: 3.04, 95% CI: 1.29-7.17), regular clients (OR: 2.20, 95% CI: 1.41-3.42), and all clients (OR: 5.87, 95% CI: 2.88-11.94), but not regular non-paying partners. Overall, community empowerment-based HIV prevention was associated with significant improvements across HIV outcomes and settings.

RESUMO

Provider-initiated HIV testing and counseling (PITC) has expanded since 2007 WHO guidelines were established. We conducted a systematic review of PITC in low- and middle-income countries. Peer-reviewed studies were included if they measured pre-post or multi-arm outcomes. Two coders abstracted data using standardized forms. Nineteen studies were included, all from sub-Saharan Africa (N = 15) or Asia (N = 4). Studies were conducted in clinics for antenatal/family planning/child health (N = 12), tuberculosis (N = 4), outpatient (N = 1), sexually transmitted diseases (N = 1), and methadone maintenance (N = 1). HIV testing uptake increased after PITC. Condom use also increased following PITC in most studies; nevirapine uptake and other outcomes were mixed. Few negative outcomes were identified. Findings support PITC as an important intervention to increase HIV testing. PITC's impact on other outcomes is mixed, but does not appear to be worse than voluntary counseling and testing. PITC should continue to be expanded and rigorously evaluated across settings and outcomes.

RESUMO

BACKGROUND: Family planning is an important public health intervention with numerous potential health benefits for all women. One of those key benefits is the prevention of mother-to-child transmission of HIV, through the prevention of unintended pregnancies among women living with HIV. METHODS: We conducted a systematic review of the effectiveness of family planning counseling interventions for HIV infected women in low- and middle-income countries. RESULTS: We found nine articles which met the inclusion criteria for this review, all from Africa. Though these studies varied in the specifics of the interventions provided, research designs and measures of outcomes, key features were discernible. Providing concerted information and support for family planning use, coupled with ready access to a wide range of contraceptive methods, seemed most effective in increasing use. Effects on pregnancy overall were difficult to measure, however: no studies assessed the effect on unintended pregnancy. CONCLUSIONS: Though these results are far from definitive, they do highlight the need for strengthened efforts to integrate family planning counseling and access to services into HIV prevention, and for greater consistency of effort over time. Studies which specifically investigate fertility intentions and desires of women living with HIV, contraception use following interventions to increase knowledge, awareness, motivation and access to the means to act on those intentions and unintended pregnancies would be valuable to help clinic personnel, programme planners and policy makers guide the development of the integrated services they offer.

RESUMO

Reaching zero-dose (ZD) children, operationally defined as children who have not received a first dose of the diphtheria, tetanus, and pertussis (DTP1) vaccine, is crucial to increase equitable immunisation coverage and access to primary health care. However, little is known about the approaches already taken by countries to improve immunisation equity. We reviewed all Health System Strengthening (HSS) proposals submitted by Gavi-supported countries from 2014 to 2021 inclusively and extracted information on interventions favouring equity. Pro-equity interventions were mapped to an analytical framework representing Gavi 5.0 programmatic guidance on reaching ZD children and missed communities. Data from keyword searches and manual screening were extracted into an Excel database. Open format responses were analysed using inductive and deductive thematic coding. Data analysis was conducted using Excel and R. Of the 56 proposals included, 51 (91%) included at least one pro-equity intervention. The most common interventions were conducting outreach sessions, tailoring the location of service delivery, and partnerships. Many proposals had "bundles" of interventions, most often involving outreach, microplanning and community-level education activities. Nearly half prioritised remote-rural areas and only 30% addressed gender-related barriers to immunisation. The findings can help identify specific interventions on which to focus future evidence syntheses, case studies and implementation research and inform discussions on what may or may not need to change to better reach ZD children and missed communities moving forward.

RESUMO

OBJECTIVE: HIV remains a significant burden, despite expanding HIV prevention tools. Long-acting injectable cabotegravir (CAB-LA) is a new preexposure prophylaxis (PrEP) product. We reviewed existing evidence to determine the efficacy and safety of CAB-LA as PrEP to inform global guidelines. DESIGN: Systematic review and meta-analysis. METHODS: We systematically reviewed electronic databases and conference abstracts for citations on CAB-LA from January 2010 to September 2021. Outcomes included HIV infection, adverse events, drug resistance, pregnancy-related adverse events, and sexual behavior. We calculated pooled effect estimates using random-effects meta-analysis and summarized other results narratively. RESULTS: We identified 12 articles/abstracts representing four multisite randomized controlled trials. Study populations included cisgender men, cisgender women, and transgender women. The pooled relative risk of HIV acquisition comparing CAB-LA to oral PrEP within efficacy studies was 0.21 (95% confidence interval: 0.07-0.61), resulting in a 79% reduction in HIV risk. Rates of adverse events were similar across study groups. Of 19 HIV infections among those randomized to CAB-LA with results available, seven had integrase strand transfer inhibitor (INSTI) resistance. Data on pregnancy-related adverse events were sparse. No studies reported on sexual behavior. CONCLUSIONS: CAB-LA is highly efficacious for HIV prevention with few safety concerns. CAB-LA may lead to an increased risk of INSTI resistance among those who have acute HIV infection at initiation or become infected while taking CAB-LA. However, results are limited to controlled studies; more research is needed on real-world implementation. Additional data are needed on the safety of CAB-LA during pregnancy (for mothers and infants) and among populations not included in the trials.
