Getting to 90: linkage to HIV care among men who have sex with men and people who inject drugs in India

Associations between HIV disclosure and HIV care continuum outcomes among men who have sex with men living with HIV: systematic review and meta-analysis

ABSTRACTThe objective of this study is to synthesize the existing empirical literature and perform a systematic review and meta-analysis on the relationship between HIV disclosure and engagement in the HIV care continuum among men who have sex with men living with HIV. Twenty-three studies were included, with thirteen quantitative studies and ten qualitative studies. Meta-analytic techniques were used to compute and aggregate effect sizes (odds ratio [OR] and their confidence intervals [95%CI]) for the quantitative studies and a thematic analysis was employed for qualitative studies. Given the small number of eligible studies, meta-analysis was only conducted for the linkage to care outcome, where a positive association was observed from the pooled estimation (OR = 1.51, 95%CI [1.15, 1.99]). Regarding ART initiation, retention in care, and viral suppression outcomes, most of the individual studies revealed a positive association between HIV disclosure and these outcomes. Thematic analysis from qualitative studies complemented the quantitative findings by incorporating the approaching and avoidance motivations underlying the relationship between non-HIV disclosure and the participation in HIV care continuum. The small number of available studies limits the definitive conclusions, and more research is needed to ascertain the magnitude of effect sizes.

A scoping review of lesbian, gay, bisexual, transgender, queer, and intersex (LGBTQI+) people's health in India

Amid incremental progress in establishing an enabling legal and policy environment for lesbian, gay, bisexual, transgender and queer-identified people, and people with intersex variations (LGBTQI+) in India, evidence gaps on LGBTQI+ health are of increasing concern. To that end, we conducted a scoping review to map and synthesize the current evidence base, identify research gaps, and provide recommendations for future research. We conducted a scoping review using the Joanna Briggs Institute methodology. We systematically searched 14 databases to identify peer-reviewed journal articles published in English language between January 1, 2010 and November 20, 2021, that reported empirical qualitative, quantitative or mixed methods data on LGBTQI+ people's health in India. Out of 3,003 results in total, we identified 177 eligible articles; 62% used quantitative, 31% qualitative, and 7% mixed methods. The majority (55%) focused on gay and other men who have sex with men (MSM), 16% transgender women, and 14% both of these populations; 4% focused on lesbian and bisexual women, and 2% on transmasculine people. Overall, studies reported high prevalence of HIV and sexually transmitted infections; multilevel risk factors for HIV; high levels of mental health burden linked to stigma, discrimination, and violence victimization; and non-availability of gender-affirmative medical care in government hospitals. Few longitudinal studies and intervention studies were identified. Findings suggest that LGBTQI+ health research in India needs to move beyond the predominant focus on HIV, and gay men/MSM and transgender women, to include mental health and non-communicable diseases, and individuals across the LGBTQI+ spectrum. Future research should build on largely descriptive studies to include explanatory and intervention studies, beyond urban to rural sites, and examine healthcare and service needs among LGBTQI+ people across the life course. Increased Indian government funding for LGBTQI+ health research, including dedicated support and training for early career researchers, is crucial to building a comprehensive and sustainable evidence base to inform targeted health policies and programs moving forward.

Drug use stigma, antiretroviral therapy use, and HIV viral suppression in a community-based sample of people with HIV who inject drugs

OBJECTIVE

To examine the association of drug use stigma with antiretroviral therapy (ART) use and HIV viral suppression among people with HIV who inject drugs in India.

DESIGN

Cross-sectional biobehavioral survey.

METHODS

Between August 2016 and May 2017, persons aged at least 18 years who reported injection drug use in the past 2 years were recruited via respondent-driven sampling (RDS) in 12 Indian cities (approximately 1000 per city). The analysis was restricted to participants with laboratory-confirmed HIV infection who self-reported a prior HIV diagnosis and were eligible for ART per concurrent national HIV treatment guidelines. Enacted and internalized drug use stigma were each measured by five to six-item subscales. The study outcomes were HIV viral suppression (<150 copies/ml) and self-reported past 30-day ART use. RDS-II weighted multivariable logistic regression with a city-level random-intercept was used to estimate adjusted odds ratios (aOR) and corresponding 95% confidence intervals (CIs).

RESULTS

Among 971 ART-eligible participants previously diagnosed with HIV, 65.1% reported ART use and 56.1% were virally suppressed. Reporting any enacted stigma (vs. none) was associated with lower odds of ART use [aOR = 0.26 (95% CI = 0.15-0.44)] and viral suppression [aOR = 0.49 (95% CI = 0.31-0.78)]. High internalized stigma scores (>median vs. ≤median) were associated with lower odds of viral suppression among participants aged at least 35 years [aOR = 0.51 (95% CI = 0.27-0.97)] but not among participants aged less than 35 years [aOR = 1.22 (95% CI = 0.57-2.60)]. Similar associations were observed in analyses restricted to participants ever linked to HIV care.

CONCLUSION

Drug use stigma may be a barrier to HIV viral suppression among people with HIV who inject drugs, thereby hindering efforts to achieve HIV control.

Strategies for retention of heterosexual men in HIV care in sub-Saharan Africa: A systematic review

Expansion of Antiretroviral Therapy (ART) programs in sub-Saharan Africa (SSA) has increased the number of people accessing treatment. However, the number of males accessing and being retained along the human immunodeficiency virus (HIV) care cascade is significantly below the UNAIDS target. Male gender has been associated with poor retention in HIV care programs, and little is known about strategies that reduce attrition of men in ART programs. This review aimed to summarize any studies on strategies to improve retention of heterosexual males in HIV care in SSA. An electronic search was conducted through Ovid^® for three databases (MEDLINE^®, Embase and Global Health). Studies reporting interventions aimed at improving retention among heterosexual men along the HIV care cascade were reviewed. The inclusion criteria included randomized-controlled trials (RCTs), prospective or retrospective cohort studies that studied adult males (≥15years of age), conducted in SSA and published between January 2005 and April 2019 with an update from 2019 to 2020. The search returned 1958 articles, and 14 studies from eight countries met the inclusion criteria were presented using the PRISMA guidelines. A narrative synthesis was conducted. Six studies explored community-based adherence support groups while three compared use of facility versus community-based delivery models. Three studies measured the effect of national identity cards, disclosure of HIV status, six-monthly clinic visits and distance from the health center. Four studies measured risk of attrition from care using hazard ratios ranging from 1.2–1.8, four studies documented attrition proportions at an average of 40.0% and two studies an average rate of attrition of 43.4/1000PYs. Most (62%) included studies were retrospective cohorts, subject to risk of allocation and outcome assessment bias. A pooled analysis was not performed because of heterogeneity of studies and outcome definitions. No studies have explored heterosexual male- centered interventions in HIV care. However, in included studies that explored retention in both males and females, there were high rates of attrition in males. More male-centered interventions need to be studied preferably in RCTs.

Predictors for Poor Linkage to Care Among Hospitalized Persons Living with HIV and Co-Occurring Substance Use Disorder

Persons living with HIV (PLWH) with substance use disorders (SUD) remain a population difficult to engage in HIV care. Project HOPE (Hospital Visits as an Opportunity for Prevention and Engagement), a randomized controlled trial testing patient navigation with/without contingency management for PLWH with SUD, aimed to address this disparity. PLWH with SUD who were out of care were recruited from 11 hospitals across the United States from 2012 to 2014. Baseline socioeconomic factors, medical mistrust scores, and perceived discrimination surveys were collected at enrollment and evaluated for effects on linkage to care at the 6-month follow-up assessment. Linkage to care (attending an outpatient visit for HIV care), early linkage to care (attending first visit within 30 days of enrollment), and engagement in care (two HIV visits within the 6-month period) were determined by medical record abstraction, supplemented by self-report. Among 801 participants enrolled in the study (mean age 45 years, 33% women, and 73% African American), those who did not complete high school and with severe food insecurity had lower odds of being linked to care at 6 months. Those with high levels of medical mistrust, recent drug use, and who did not complete high school had lower odds of early linkage to care. Early linkage was associated with higher odds of engagement at 6 months and was mitigated by both patient navigator interventions (all p < .05). Addressing social determinants of health is critical to correct the disparity seen in HIV outcomes among PLWH with SUD. Identifying factors that alter the effect of interventions could help identify patients who would benefit most.

Making the Link: A Pilot Health Navigation Intervention to Improve Timely Linkage to Care for Men Who have Sex with Men and Transgender Women Recently Diagnosed with HIV in Guatemala City

We piloted a health navigation strategy to promote timely linkage to care among men who have sex with men (MSM) and transgender women (TW) recently diagnosed with HIV in Guatemala City. We used a mixed-methods approach, integrating quantitative data collected during clinic visits and qualitative data from in-depth interviews, to characterize acceptability of navigation and time to linkage, defined as having the first clinical care visit. Out of 54 participants who enrolled in the pilot (n = 52 MSM; n = 2 TW), 50 (92.6%) accepted navigation and all were linked to care. Median time to linkage was 3 days (Interquartile Range 2-5 days). In qualitative interviews, participants expressed feeling scared and alone following their diagnosis and appreciated the support of a navigator, especially when they did not feel they could access their existing support networks. Future research and evaluation should continue to assess how to best use health navigation to support key populations recently diagnosed with HIV.

Individual and Network Factors Associated With HIV Care Continuum Outcomes Among Nigerian MSM Accessing Health Care Services

BACKGROUND AND SETTING

Because data on the determinants of the HIV care continuum from key populations such as men who have sex with men (MSM) in resource-limited settings are limited, the study aimed to characterize HIV care continuum outcomes and assess individual and network barriers to progression through the HIV care continuum among MSM in Abuja and Lagos, Nigeria.

METHODS

TRUST/RV368 study used respondent-driven sampling to accrue MSM into community-based clinics in Nigeria. Participants received HIV testing at enrollment. HIV-infected participants were offered antiretroviral therapy (ART) with HIV RNA testing every 3 months (Abuja) or 6 months (Lagos). Multiple logistic regression models were used to calculate adjusted odds ratios for factors associated with each point in the HIV care continuum, including HIV testing, ART initiation, and 6-month viral suppression.

RESULTS

A total of 1506 MSM were recruited, 1178 (78.2%) tested for HIV and 369 (31.3%) were HIV positive newly diagnosed. Of these, 188 (50.1%) initiated ART, 136 (72.3%) completed 6 months, and 96 (70.6%) were virally suppressed. Larger network size and stronger social network support were each positively associated with HIV testing uptake. Factors associated with ART initiation were higher education and stronger social network support. Having stronger social network support was associated with increased odds of viral suppression at 6 months.

CONCLUSIONS

Social determinants of health potentiated increased HIV care continuum outcomes. Integration of HIV prevention, HIV counseling and testing services, and universal coverage of ART into a community-based clinic is critical in achieving better HIV care continuum outcomes.

Overlap between harm reduction and HIV service utilisation among PWID in India: Implications for HIV combination prevention

BACKGROUND

In some regions, HIV incidence is rising among people who inject drugs (PWID). Combination prevention approaches are well suited to PWID who face multiple sources of HIV risk. This analysis investigates patterns of utilisation to basic HIV services (HIV counselling and testing [HCT], antiretroviral therapy [ART]) as well as harm reduction programs (needle and syringe exchange programs [NSEP] and opioid agonist therapy [OAT]) among PWID and how utilisation of harm reduction services is associated with HIV-related care seeking behaviours.

METHODS

Respondent-driven sampling was used to recruit 14,481 PWID across 15 cities in India. Sampling-weighted multilevel logistic regression models assessed associations between utilisation of harm reduction service and HCT and ART use among those indicated (90.3% and 5.0% of full sample, respectively). We considered both recent (prior year) and ever use of services.

RESULTS

Overall, 42.3% reported prior HIV testing and 57.9% of eligible persons reported ART initiation, but overlap with NSEP and OAT use was limited. In adjusted models, recent and ever use of both NSEP and OAT were significantly associated with recent and ever HCT utilisation, respectively; however, harm reduction utilisation was not associated with ART initiation among eligible participants.

CONCLUSIONS

Harm reduction services may play a key role in linking PWID with HIV testing; however, they were not associated with ART initiation among eligible individuals. Moreover, a large majority who utilised NSEP and OAT were not engaged in optimal HIV care or prevention, highlighting missed opportunities and a need for stronger linkages between NSEP/OAT and HIV care and treatment, particularly among those actively injecting. These findings provide key insights to better understand how services can be linked or combined to optimise service utilisation among PWID.

Opportunities for Enhanced Strategic Use of Surveys, Medical Records, and Program Data for HIV Surveillance of Key Populations: Scoping Review

BACKGROUND

Normative guidelines from the World Health Organization recommend tracking strategic information indicators among key populations. Monitoring progress in the global response to the HIV epidemic uses indicators put forward by the Joint United Nations Programme on HIV/AIDS. These include the 90-90-90 targets that require a realignment of surveillance data, routinely collected program data, and medical record data, which historically have developed separately.

OBJECTIVE

The aim of this study was to describe current challenges for monitoring HIV-related strategic information indicators among key populations ((men who have sex with men [MSM], people in prisons and other closed settings, people who inject drugs, sex workers, and transgender people) and identify future opportunities to enhance the use of surveillance data, programmatic data, and medical record data to describe the HIV epidemic among key populations and measure the coverage of HIV prevention, care, and treatment programs.

METHODS

To provide a historical perspective, we completed a scoping review of the expansion of HIV surveillance among key populations over the past three decades. To describe current efforts, we conducted a review of the literature to identify published examples of SI indicator estimates among key populations. To describe anticipated challenges and future opportunities to improve measurement of strategic information indicators, particularly from routine program and health data, we consulted participants of the Third Global HIV Surveillance Meeting in Bangkok, where the 2015 World Health Organization strategic information guidelines were launched.

RESULTS

There remains suboptimal alignment of surveillance and programmatic data, as well as routinely collected medical records to facilitate the reporting of the 90-90-90 indicators for HIV among key populations. Studies (n=3) with estimates of all three 90-90-90 indicators rely on cross-sectional survey data. Programmatic data and medical record data continue to be insufficiently robust to provide estimates of the 90-90-90 targets for key populations.

CONCLUSIONS

Current reliance on more active data collection processes, including key population-specific surveys, remains warranted until the quality and validity of passively collected routine program and medical record data for key populations is optimized.

Hepatitis C care continuum and associated barriers among people who inject drugs in Chennai, India

BACKGROUND

Little is known regarding barriers to hepatitis C virus (HCV) treatment among people who inject drugs (PWID) in low-resource settings, particularly in the era of direct-acting antiviral therapies.

METHODS

Between March, 2015-August, 2016, a cross-sectional survey was administered to community-based PWID in Chennai, India to examine the HCV care continuum and associated barriers. Adjusted prevalence ratios (APR) were estimated by multivariable Poisson regression with robust variance.

RESULTS

All participants were male (n = 541); 152 participants had HCV mono-infection and 61 participants had HIV/HCV co-infection. Only one HCV mono-infected and one HIV/HCV co-infected participant was linked to HCV care. Overall, there was moderate knowledge of HCV disease but poor knowledge of HCV treatment. Higher total knowledge scores were negatively associated with HIV/HCV co-infection (vs. HCV mono-infection), though this was not statistically significant in adjusted analysis (APR = 0.71 [95%CI = 0.47-1.06]). Participants ≥45 years (APR = 0.73 [95%CI = 0.58-0.92]) and participants with HIV/HCV co-infection (APR = 0.64 [95%CI = 0.47-0.87]) were less willing to take weekly interferon injections for 12 weeks. Willingness to undergo HCV treatment improved with decreasing duration of therapy, higher perceived efficacy, and use of pills vs. interferon, though willingness to use interferon improved with decreasing duration of therapy. Most participants preferred daily visits to a clinic for HCV treatment versus receiving a month's supply. Participants ≥45 years (vs. <45 years; APR = 0.70 [95%CI = 0.56-0.88]) and participants with HIV/HCV co-infection (APR = 0.75 [95%CI = 0.57-0.98]) were less likely to intend on seeking HCV care. Common reasons for not having already seen a provider for HCV treatment differed by HIV status, and included low perceived need for treatment (HCV-mono-infected), competing money/health priorities and costs/fears about treatment (HIV/HCV-co-infected).

CONCLUSION

Residual gaps in HCV knowledge and continuing negative perceptions related to interferon-based therapy highlight the need to scale-up educational initiatives. Readiness for HCV treatment was particularly low among HIV/HCV co-infected and older PWID, emphasizing the importance of tailored treatment strategies.

HIV viral load monitoring among key populations in low- and middle-income countries: challenges and opportunities

Introduction

Key populations bear a disproportionate HIV burden and have substantial unmet treatment needs. Routine viral load monitoring represents the gold standard for assessing treatment response at the individual and programme levels; at the population‐level, community viral load is a metric of HIV programme effectiveness and can identify “hotspots” of HIV transmission. Nevertheless, there are specific implementation and ethical challenges to effectively operationalize and meaningfully interpret viral load data at the community level among these often marginalized populations.

Discussion

Viral load monitoring enhances HIV treatment, and programme evaluation, and offers a better understanding of HIV surveillance and epidemic trends. Programmatically, viral load monitoring can provide data related to HIV service delivery coverage and quality, as well as inequities in treatment access and uptake. From a population perspective, community viral load data provides information on HIV transmission risk. Furthermore, viral load data can be used as an advocacy tool to demonstrate differences in service delivery and to promote allocation of resources to disproportionately affected key populations and communities with suboptimal health outcomes. However, in order to perform viral load monitoring for individual and programme benefit, health surveillance and advocacy purposes, careful consideration must be given to how such key population programmes are designed and implemented. For example, HIV risk factors, such as particular sex practices, sex work and drug use, are stigmatized or even criminalized in many contexts. Consequently, efforts must be taken so that routine viral load monitoring among marginalized populations does not cause inadvertent harm. Furthermore, given the challenges of reaching representative samples of key populations, significant attention to meaningful recruitment, decentralization of care and interpretation of results is needed. Finally, improving the interoperability of health systems through judicious use of biometrics or identifiers when confidentiality can be maintained is important to generate more valuable data to inform monitoring programmes.

Conclusions

Opportunities for expanded viral load monitoring could and should benefit all those affected by HIV, including key populations. The promise of the increasing routinization of viral load monitoring as a tool to advance HIV treatment equity is great and should be prioritized and appropriately implemented within key population programmatic and research agendas.

HIV Linkage to Care and Retention in Care Rate Among MSM in Guangzhou, China

Quantifying HIV service provision along the HIV care continuum is increasingly important for monitoring and evaluating HIV interventions. We examined factors associated with linkage and retention in care longitudinally among MSM (n = 1974, 4933 person-years) diagnosed and living in Guangzhou, China, in 2008-2014. We measured longitudinal change of retention in care (≥2 CD4 tests per year) from linkage and antiretroviral therapy initiation (ART). We examined factors associated with linkage using logistic regression and with retention using generalized estimating equations. The rate of linkage to care was 89% in 2014. ART retention rate dropped from 71% (year 1) to 46% (year 2), suggesting that first-year retention measures likely overestimate retention over longer periods. Lower CD4 levels and older age predicted retention in ART care. These data can inform interventions to improve retention about some subgroups.

"Oh, I'm Not Alone": Experiences of HIV-Positive Men Who Have Sex With Men in a Health Navigation Program to Promote Timely Linkage to Care in Guatemala City

Men who have sex with men (MSM) are disproportionately affected by HIV in Guatemala and may benefit from health navigation programs designed to support timely linkage to HIV care. We conducted qualitative in-depth interviews with MSM (n = 19) linked to care within days of their diagnosis with the support of a health navigator. We used narrative analysis and systematic coding to identify themes related to HIV diagnosis and experiences with navigators. Participants experienced strong feelings of fear upon receiving a positive HIV test result. This fear led to social isolation and limited reliance on family and friend networks for support. Health navigators developed strong relationships with participants by providing the emotional support they were lacking and supporting them to overcome their fear and other structural barriers to HIV care, including stigma. Findings support the important role of navigation for MSM in Guatemala and could be transferable to other settings in Latin America.

Association between internalized stigma and depression among HIV-positive persons entering into care in Southern India

BACKGROUND

In India, which has the third largest HIV epidemic in the world, depression and HIV-related stigma may contribute to high rates of poor HIV-related outcomes such as loss to care and lack of virologic suppression.

METHODS

We analyzed data from a large HIV treatment center in southern India to estimate the burden of depressive symptoms and internalized stigma among Indian people living with HIV (PLHIV) entering into HIV care and to test the hypothesis that probable depression was associated with internalized stigma. We fitted modified Poisson regression models, adjusted for sociodemographic variables, with probable depression (PHQ-9 score ≥10 or recent suicidal thoughts) as the outcome variable and the Internalized AIDS-Related Stigma Scale (IARSS) score as the explanatory variable.

FINDINGS

521 persons (304 men and 217 women) entering into HIV care between January 2015 and May 2016 were included in the analyses. The prevalence of probable depression was 10% and the mean IARSS score was 2.4 (out of 6), with 82% of participants endorsing at least one item on the IARSS. There was a nearly two times higher risk of probable depression for every additional point on the IARSS score (Adjusted Risk Ratio: 1.83; 95% confidence interval, 1.56-2.14).

CONCLUSIONS

Depression and internalized stigma are highly correlated among PLHIV entering into HIV care in southern India and may provide targets for policymakers seeking to improve HIV-related outcomes in India.

Challenges and emerging opportunities for the HIV prevention, treatment and care cascade in men who have sex with men in Asia Pacific

In Asia Pacific, most countries have expanded HIV treatment guidelines to include all those with HIV infection and adopted antiretroviral treatment for prevention (TFP) as a blanket strategy for HIV control. Although the overall epidemic development associated with this focus is positive, the HIV epidemic in men who have sex with men (MSM) is continuing unperturbed without any signs of decline or reversal. This raises doubt about whether TFP as a blanket HIV prevention policy is the right approach. This paper reviews currently available biomedical HIV prevention strategies, national HIV prevention policies and guidelines from selected countries and published data on the HIV cascade in MSM. No evidence for efficacy of TFP in protecting MSM from HIV infection was found. The rationale for this approach is based on assumptions about biological plausibility and external validity of latency-based efficacy found in heterosexual couples. This is different from the route and timing of HIV transmission in MSM. New HIV infections in MSM principally occur in chains of acutely HIV-infected highly sexually active young men, in whom acquisition and transmission are correlated in space and time. By the time TFP renders its effects, most new HIV infections in MSM will have already occurred. On a global level, less than 6% of all reports regarding the HIV care cascade from 1990 to 2016 included MSM, and only 2.3% concerned MSM in low/middle-income countries. Only one report originated from Asia Pacific. Generally, HIV cascade data in MSM show a sobering picture of TFP in engaging and retaining MSM along the continuum. Widening the cascade with a preventive extension, including pre-exposure prophylaxis, the first proven efficacious and only biomedical HIV prevention strategy in MSM, will be instrumental in achieving HIV epidemic control in this group.
