RESUMEN

The US President's Emergency Plan for AIDS Relief (PEPFAR) supports aggressive scale-up of antiretroviral therapy (ART) in high-burden countries and across all genders and populations at risk toward global human immunodeficiency virus (HIV) epidemic control. PEPFAR recognizes the risk of HIV drug resistance (HIVDR) as a consequence of aggressive ART scale-up and is actively promoting 3 key steps to mitigate the impact of HIVDR: (1) routine access to routine viral load monitoring in all settings; (2) optimization of ART regimens; and (3) routine collection and analysis of HIVDR data to monitor the success of mitigation strategies. The transition to dolutegravir-based regimens in PEPFAR-supported countries and the continuous evolution of HIVDR surveillance strategies are essential elements of PEPFAR implementation.

RESUMEN

BACKGROUND: In 2014, the Joint United Nations Program on HIV/AIDS (UNAIDS) issued treatment goals for human immunodeficiency virus (HIV). The 90-90-90 target specifies that by 2020, 90% of individuals living with HIV will know their HIV status, 90% of people with diagnosed HIV infection will receive antiretroviral treatment (ART), and 90% of those taking ART will be virally suppressed. Consistent methods and routine reporting in the public domain will be necessary for tracking progress towards the 90-90-90 target. METHODS AND FINDINGS: For the period 2010-2016, we searched PubMed, UNAIDS country progress reports, World Health Organization (WHO), UNAIDS reports, national surveillance and program reports, United States President's Emergency Plan for AIDS Relief (PEPFAR) Country Operational Plans, and conference presentations and/or abstracts for the latest available national HIV care continuum in the public domain. Continua of care included the number and proportion of people living with HIV (PLHIV) who are diagnosed, on ART, and virally suppressed out of the estimated number of PLHIV. We ranked the described methods for indicators to derive high-, medium-, and low-quality continuum. For 2010-2016, we identified 53 national care continua with viral suppression estimates representing 19.7 million (54%) of the 2015 global estimate of PLHIV. Of the 53, 6 (with 2% of global burden) were high quality, using standard surveillance methods to derive an overall denominator and program data from national cohorts for estimating steps in the continuum. Only nine countries in sub-Saharan Africa had care continua with viral suppression estimates. Of the 53 countries, the average proportion of the aggregate of PLHIV from all countries on ART was 48%, and the proportion of PLHIV who were virally suppressed was 40%. Seven countries (Sweden, Cambodia, United Kingdom, Switzerland, Denmark, Rwanda, and Namibia) were within 12% and 10% of achieving the 90-90-90 target for "on ART" and for "viral suppression," respectively. The limitations to consider when interpreting the results include significant variation in methods used to determine national continua and the possibility that complete continua were not available through our comprehensive search of the public domain. CONCLUSIONS: Relatively few complete national continua of care are available in the public domain, and there is considerable variation in the methods for determining progress towards the 90-90-90 target. Despite bearing the highest HIV burden, national care continua from sub-Saharan Africa were less likely to be in the public domain. A standardized monitoring and evaluation approach could improve the use of scarce resources to achieve 90-90-90 through improved transparency, accountability, and efficiency.

RESUMEN

Background/Aims HIV continues to be a major public health threat in the United States, and mathematical modeling has demonstrated that the universal effective use of antiretroviral therapy among all HIV-positive individuals (i.e. the "test and treat" approach) has the potential to control HIV. However, to accomplish this, all the steps that define the HIV care continuum must be achieved at high levels, including HIV testing and diagnosis, linkage to and retention in clinical care, antiretroviral medication initiation, and adherence to achieve and maintain viral suppression. The HPTN 065 (Test, Link-to-Care Plus Treat [TLC-Plus]) study was designed to determine the feasibility of the "test and treat" approach in the United States. Methods HPTN 065 was conducted in two intervention communities, Bronx, NY, and Washington, DC, along with four non-intervention communities, Chicago, IL; Houston, TX; Miami, FL; and Philadelphia, PA. The study consisted of five components: (1) exploring the feasibility of expanded HIV testing via social mobilization and the universal offer of testing in hospital settings, (2) evaluating the effectiveness of financial incentives to increase linkage to care, (3) evaluating the effectiveness of financial incentives to increase viral suppression, (4) evaluating the effectiveness of a computer-delivered intervention to decrease risk behavior in HIV-positive patients in healthcare settings, and (5) administering provider and patient surveys to assess knowledge and attitudes regarding the use of antiretroviral therapy for prevention and the use of financial incentives to improve health outcomes. The study used observational cohorts, cluster and individual randomization, and made novel use of the existing national HIV surveillance data infrastructure. All components were developed with input from a community advisory board, and pragmatic methods were used to implement and assess the outcomes for each study component. Results A total of 76 sites in Washington, DC, and the Bronx, NY, participated in the study: 37 HIV test sites, including 16 hospitals, and 39 HIV care sites. Between September 2010 and December 2014, all study components were successfully implemented at these sites and resulted in valid outcomes. Our pragmatic approach to the study design, implementation, and the assessment of study outcomes allowed the study to be conducted within established programmatic structures and processes. In addition, it was successfully layered on the ongoing standard of care and existing data infrastructure without disrupting health services. Conclusion The HPTN 065 study demonstrated the feasibility of implementing and evaluating a multi-component "test and treat" trial that included a large number of community sites and involved pragmatic approaches to study implementation and evaluation.

RESUMEN

The World Health Organization (WHO) recommends viral load testing as the preferred method for monitoring the clinical response of patients with human immunodeficiency virus (HIV) infection to antiretroviral therapy (ART) (1). Viral load monitoring of patients on ART helps ensure early diagnosis and confirmation of ART failure and enables clinicians to take an appropriate course of action for patient management. When viral suppression is achieved and maintained, HIV transmission is substantially decreased, as is HIV-associated morbidity and mortality (2). CDC and other U.S. government agencies and international partners are supporting multiple countries in sub-Saharan Africa to provide viral load testing of persons with HIV who are on ART. This report examines current capacity for viral load testing based on equipment provided by manufacturers and progress with viral load monitoring of patients on ART in seven sub-Saharan countries (Côte d'Ivoire, Kenya, Malawi, Namibia, South Africa, Tanzania, and Uganda) during January 2015-June 2016. By June 2016, based on the target numbers for viral load testing set by each country, adequate equipment capacity existed in all but one country. During 2015, two countries tested >85% of patients on ART (Namibia [91%] and South Africa [87%]); four countries tested <25% of patients on ART. In 2015, viral suppression was >80% among those patients who received a viral load test in all countries except Côte d'Ivoire. Sustained country commitment and a coordinated global effort is needed to reach the goal for viral load monitoring of all persons with HIV on ART.

RESUMEN

In 2006, the District of Columbia Department of Health (DC DOH) launched initiatives promoting routine HIV testing and improved linkage to care in support of revised the Centers for Disease Control and Prevention (CDC) HIV-testing guidelines. An ecological analysis was conducted using population-based surveillance data to determine whether these efforts were temporally associated with increased and earlier identification of HIV/AIDS cases and improved linkages to care. Publically funded HIV-testing data and HIV/AIDS surveillance data from 2005 to 2009 were used to measure the number of persons tested, new diagnoses, timing of entry into care, CD4 at diagnosis and rates of progression to AIDS. Tests for trend were used to determine whether statistically significant changes in these indicators were observed over the five-year period. Results indicated that from 2005 to 2009, publically funded testing increased 4.5-fold; the number of newly diagnosed HIV/AIDS cases remained relatively constant. Statistically significant increases in the proportion of cases entering care within three months of diagnosis were observed (p < 0.0001). Median CD4 counts at diagnosis increased over the five-year time period from 346 to 379 cells/µL. The proportion of cases progressing from HIV to AIDS and diagnosed with AIDS initially, decreased significantly (both p < 0.0001). Routine HIV testing and linkage to care efforts in the District of Columbia were temporally associated with earlier diagnoses of cases, more timely entry into HIV-specialized care, and a slowing of HIV disease progression. The continued use of surveillance data to measure the community-level impact of other programmatic initiatives including test and treat strategies will be critical in monitoring the response to the District's HIV epidemic.

RESUMEN

BACKGROUND AND SETTING: The Botswana Combination Prevention Project demonstrated a 30% reduction in community HIV incidence through expanded HIV testing, enhanced linkage to care, and universal antiretroviral treatment and exceeded the Joint United Nations Programme on HIV/AIDS 90-90-90 targets. We report rates and characteristics of incident HIV infections. METHODS: The Botswana Combination Prevention Project was a community-randomized controlled trial conducted in 30 rural/periurban Botswana communities from 2013 to 2017. Home-based and mobile HIV-testing campaigns were conducted in 15 intervention communities, with 39% of participants testing at least twice. We assessed the HIV incidence rate [IR; number of new HIV infections per 100 person-years (py) at risk] among repeat testers and risk factors with a Cox proportional hazards regression model. RESULTS: During 27,517 py, 195 (women: 79%) of 18,597 became HIV-infected (0.71/100 py). Women had a higher IR (1.01/100 py; 95% confidence interval: 0.99 to 1.02) than men (0.34/100 py; 95% confidence interval: 0.33 to 0.35). The highest IRs were among women aged 16-24 years (1.87/100 py) and men aged 25-34 years (0.56/100 py). The lowest IRs were among those aged 35-64 years (women: 0.41/100 py; men: 0.20/100 py). The hazard of incident infection was the highest among women aged 16-24 years (hazard ratio = 7.05). Sex and age were significantly associated with incidence (both P < 0.0001). CONCLUSIONS: Despite an overall reduction in HIV incidence and approaching the United Nations Programme on HIV/AIDS 95-95-95 targets, high HIV incidence was observed in adolescent girls and young women. These findings highlight the need for additional prevention services (pre-exposure prophylaxis and DREAMS) to achieve epidemic control in this subpopulation and increased efforts with men with undiagnosed HIV.

RESUMEN

INTRODUCTION: Until COVID-19, tuberculosis (TB) was the leading infectious disease killer globally, disproportionally affecting people with HIV. The COVID-19 pandemic is threatening the gains made in the fight against both diseases. DISCUSSION: Although crucial guidance has been released on how to maintain TB and HIV services during the pandemic, it is acknowledged that what was considered normal service pre-pandemic needs to improve to ensure that we rebuild person-centred, inclusive and quality healthcare services. The threat that the pandemic may reverse gains in the response to TB and HIV may be turned into an opportunity by pivoting to using proven differentiated service delivery approaches and innovative technologies that can be used to maintain care during the pandemic and accelerate improved service delivery in the long term. Models of care should be convenient, supportive and sufficiently differentiated to avoid burdensome clinic visits for medication pick-ups or directly observed treatments. Additionally, the pandemic has highlighted the chronic and short-sighted lack of investment in health systems and the need to prioritize research and development to close the gaps in TB diagnosis, treatment and prevention, especially for children and people with HIV. Most importantly, TB-affected communities and civil society must be supported to lead the planning, implementation and monitoring of TB and HIV services, especially in the time of COVID-19 where services have been disrupted, and to report on legal, policy and gender-related barriers to access experienced by affected people. This will help to ensure that TB services are held accountable by affected communities for delivering equitable access to quality, affordable and non-discriminatory services during and beyond the pandemic. CONCLUSIONS: Successfully reaching the related targets of ending TB and AIDS as public health threats by 2030 requires rebuilding of stronger, more inclusive health systems by advancing equitable access to quality TB services, including for people with HIV, both during and after the COVID-19 pandemic. Moreover, services must be rights-based, community-led and community-based, to ensure that no one is left behind.

RESUMEN

BACKGROUND: Increasing HIV treatment coverage is crucial to reducing population-level HIV incidence. METHODS: The Botswana Combination Prevention Project (BCPP) was a community randomized trial examining the impact of multiple prevention interventions on population-level HIV incidence and was conducted from October 2013 through June 2017. Home and mobile campaigns offered HIV testing to all individuals ≥ age 16. All identified HIV-positive persons who were not on antiretroviral therapy (ART) were referred to treatment and tracked to determine linkage to care, ART status, retention in treatment, and viral suppression. RESULTS: Of an estimated total of 14,270 people living with HIV (PLHIV) residing in the 15 intervention communities, BCPP identified 13,328 HIV-positive persons (93%). At study start, 10,703 (80%) of estimated PLHIV knew their status; 2,625 (20%) learned their status during BCPP, a 25% increase with the greatest increases occurring among men (37%) and youth (77%). At study start, 9,258 (65%) of estimated PLHIV were on ART. An additional 3,001 persons started ART through the study. By study end, 12,259 had initiated and were retained on ART, increasing coverage to 93%. A greater increase in ART coverage was achieved among men (40%) compared to women (29%). Of the 11,954 persons who had viral load (VL) test results, 11,687 (98%) were virally suppressed (HIV-1 RNA ≤400 copies/mL). Overall, 82% had documented VL suppression by study end. CONCLUSIONS: Knowledge of HIV-positive status and ART coverage increased towards 95-95 targets with universal testing, linkage interventions, and ART. The increases in HIV testing and ART use among men and youth were essential to reaching these targets. CLINICAL TRIAL NUMBER: NCT01965470.

RESUMEN

INTRODUCTION: The scale-up of Universal Test and Treat has resulted in reductions in HIV morbidity, mortality and incidence. However, healthcare system and personal challenges have impacted the levels of treatment coverage achieved. We implemented interventions to improve linkage to care, retention, viral load (VL) coverage and service delivery, and describe the HIV care cascade over the course of the Botswana Combination Prevention Project (BCPP) study. METHODS: BCPP was designed to evaluate the impact of prevention interventions on HIV incidence in 30 communities in Botswana. We followed a longitudinal cohort of newly identified and known HIV-positive persons not on antiretroviral therapy (ART) identified through community-based testing activities through BCPP and referred with appointments to local HIV clinics in 15 intervention communities. Those who did not keep the first or follow-up appointments were tracked and traced through phone and home contacts. Improvements to service delivery models in the intervention clinics were also implemented. RESULTS: A total of 3,657 newly identified or HIV-positive persons not on ART were identified and referred to their local HIV clinic; 90% (3,282/3,657) linked to care and of those, 93% (3,066/3,282) initiated treatment. Near the end of the study, 221 persons remained >90 days late for appointments or missing. Tracing efforts identified 54/3,066 (2%) persons who initiated treatment but died, and 106/3,066 (3%) persons were located and returned to treatment. At study end, 61/3,066 (2%) persons remained missing and were never reached. Overall, 2,951 (98%) persons living with HIV (PLHIV) who initiated treatment were still alive, retained in care and still receiving ART out of the 3,001 persons alive at the end of the study. Of those on ART, 2,854 (97%) had current VL results and 2,784 (98%) of those were virally suppressed at study end. CONCLUSIONS: This study achieved high rates of linkage, treatment initiation, retention and VL coverage and suppression in a cohort of newly identified and known PLHIV not on ART. Tracking and tracing interventions effectively identified those persons who needed more resource intensive follow-up. The interventions implemented to improve service delivery and data quality may have also contributed to high linkage and retention rates. Clinical trial number: NCT01965470.

RESUMEN

The main objective of this paper was to identify HIV risk factors at the individual, partner, and partnership levels among married, lifetime monogamous women in a nationally representative sample of Zimbabweans aged 15-29 years. Cross-sectional data were collected through individual survey interviews among 1,286 women who provided blood for HIV testing. The HIV prevalence among these women was high (21.8%). HIV risk increased with female age, within-couple age difference of more than 5 years, the husband having children with other women, and the respondent being 'extremely likely' to discuss monogamy in the next 3 months with her husband. The latter suggests that women were attempting to communicate their concerns while unaware that they were already HIV positive. HIV risk largely appears related to the partner's past and present sexual behavior, resulting in limited ability for married women to protect themselves from infection. Overall, lifetime monogamy offers insufficient protection for women.

RESUMEN

BACKGROUND: Increased funding for global human immunodeficiency virus prevention and control in developing countries has created both a challenge and an opportunity for achieving long-term global health goals. This paper describes a programme in Zimbabwe aimed at responding more effectively to the HIV/AIDS epidemic by reinforcing a critical competence-based training institution and producing public health leaders. METHODS: The programme used new HIV/AIDS programme-specific funds to build on the assets of a local education institution to strengthen and expand the general public health leadership capacity in Zimbabwe, simultaneously ensuring that they were trained in HIV interventions. RESULTS: The programme increased both numbers of graduates and retention of faculty. The expanded HIV/AIDS curriculum was associated with a substantial increase in trainee projects related to HIV. The increased number of public health professionals has led to a number of practically trained persons working in public health leadership positions in the ministry, including in HIV/AIDS programmes. CONCLUSION: Investment of a modest proportion of new HIV/AIDS resources in targeted public health leadership training programmes can assist in building capacity to lead and manage national HIV and other public health programmes.

RESUMEN

The Maputo Declaration of 2008 advocated for commitment from global stakeholders and national governments to prioritise support and harmonisation of laboratory systems through development of comprehensive national laboratory strategies and policies in sub-Saharan Africa. As a result, HIV laboratory medicine in Africa has undergone a transformation, and substantial improvements have been made in diagnostic services, networks, and institutions, including the development of a competent workforce, introduction of point-of-care diagnostics, and innovative quality improvement programmes that saw more than 1100 laboratories enrolled and 44 accredited to international standards. These improved HIV laboratories can now be used to combat emerging continental and global health threats in the decades to come. For instance, the unprecedented Ebola virus disease outbreak in west Africa exposed the severe weaknesses in the overall national health systems in affected countries. It is now possible to build robust health-care systems in Africa and to combat emerging continental and global health threats in the future. In this Personal View, we aim to describe the remarkable transformation that has occurred in laboratory medicine to combat HIV/AIDS and improve global health in sub-Saharan Africa since 2008.

RESUMEN

Supervised dosing is a cornerstone of tuberculosis treatment. HIV treatment strategies that use directly administered antiretroviral therapy (DAART) are increasingly being assessed. In a prospective single-arm clinical trial, we enrolled methadone-maintained, HIV-infected participants to receive supervised doses of antiretroviral therapy (ART) on days when they received methadone. Other ART doses were self-administered. In this analysis we examined factors associated with retention to DAART, adherence to supervised doses, and virologic failure. Factors associated with retention to DAART were assessed with the Kaplan-Meier method and Cox proportional hazards models. Factors associated with nonadherence with supervised dosing and with virologic failure were assessed by logistic regression and techniques for longitudinal data analysis. A total of 16,453 supervised doses were administered to 88 participants over a median follow-up of 9.4 months. The median participant adherence with supervised dosing was 83%. Active drug use, determined by urine drug screens, was associated twofold increased risks of both intervention dropout and nonadherence with supervised doses. Adherence with supervised doses was strongly associated with virologic failure. Because DAART was administered only on methadone dosing days, fewer than half of the total ART doses were scheduled to be supervised in most participants. The percent of doses that was scheduled to be supervised was not associated with either adherence or with virologic failure. Given that a relatively small proportion of the total ART doses were supervised in many patients, future studies should assess how DAART affects adherence with nonsupervised doses and retention to ART.

RESUMEN

BACKGROUND: Directly administered antiretroviral therapy (DAART) in methadone clinics has the potential to improve treatment outcomes for human immunodeficiency virus (HIV)-infected injection drug users (IDUs). METHODS: DAART was provided at 3 urban methadone clinics. Eighty-two participants who were initiating or reinitiating highly active antiretroviral therapy (HAART) received supervised doses of therapy at the clinic on the mornings on which they received methadone. Treatment outcomes in the DAART group were compared with outcomes in 3 groups of concurrent comparison patients, who were drawn from the Johns Hopkins HIV Cohort. The concurrent comparison patients were taking HAART on a self-administered basis. The 3 groups of concurrent comparison patients were as follows: patients with a history of IDU who were receiving methadone at the time HAART was used (the IDU-methadone group; 75 patients), patients with a history of IDU who were not receiving methadone at the time that HAART was used (the IDU-nonmethadone group; 244 patients), and patients with no history of IDU (the non-IDU group; 490 patients). RESULTS: At 12 months, 56% of DAART participants achieved an HIV type 1 RNA level <400 copies/mL, compared with 32% of participants in the IDU-methadone group (P=.009), 33% of those in the IDU-nonmethadone group (P=.001), and 44% of those in the non-IDU group (P=.077). The DAART group experienced a median increase in the CD4 cell count of 74 cells/mm3, compared with 21 cells/mm3 in the IDU-methadone group (P=.04), 33 cells/mm3 in the IDU-nonmethadone group (P=.09), and 84 cells/mm3 in the non-IDU group (P=.98). After adjustment for other covariates in a logistic regression model, DAART participants were significantly more likely to achieve viral suppression than were patients in each of the 3 comparison groups. CONCLUSIONS: These results suggest that methadone clinic-based DAART has the potential to provide substantial clinical benefit for HIV-infected IDUs.

RESUMEN

BACKGROUND: A randomized, controlled trial was conducted to evaluate the impact of a directly administered antiretroviral therapy program (DAART) and intensive adherence case management (IACM) intervention on virologic and immunologic response to highly active antiretroviral therapy (HAART) among patients at 3 public human immunodeficiency virus clinics in Los Angeles County, California. METHODS: Participants included 250 treatment-naive and treatment-experienced persons for whom no more than 1 prior HAART regimen had failed. Five days per week for 6 months, a community worker delivered 1 HAART dose to DAART participants and observed the participant take it. IACM participants met weekly with a case manager to overcome barriers to HAART adherence. A control group (the standard of care [SOC] group) received the usual care. RESULTS: The majority of patients were Latino (64%) or African American (24%); 57% were monolingual Spanish speakers. Seventy-five percent of the patients were male, and 64% reported an annual income of <10,000 dollars. In an intent-to-treat analysis, no statistical differences were observed in the percentage of patients with an undetectable viral load (i.e., <400 copies/mL) at 6 months between the DAART group (54%), IACM group (60%), and SOC group (54%; P>.05). An on-treatment analysis determined that there were no statistical differences in the percentage of patients with an undetectable viral load at 6 months between the DAART group (71%), IACM group (80%), and SOC group (74%; P>.05). Additionally, there were no statistical differences in 6-month changes in the CD4+ cell count or in self-reported adherence to therapy. CONCLUSIONS: Among patients with limited prior HAART experience and adherence barriers that had not been assessed before randomization, no differences were found in virologic or immunologic response for DAART or IACM, compared with SOC, at 6 months. DAART and IACM did not improve short-term outcomes when SOC included other means of adherence support that were not controlled for by the study design.

RESUMEN

Methadone-maintenance treatment clinics are strategically appealing sites for provision of directly administered antiretroviral therapy (DAART) to human immunodeficiency virus type 1 (HIV-1)-infected injection drug users (IDUs). We initiated an ongoing DAART protocol at a university-associated methadone clinic in April 2001, which continues to enroll participants. Participants ingested antiretroviral medications under direct supervision on days they attended the clinic; evening doses and doses on "methadone take-home days" were self-administered. Comparison IDUs receiving either standard care or treatment-adherence support were randomly selected from the population of the HIV-1 clinic where DAART participants received their primary care for HIV-1 infection, with frequency matching by sex, prior antiretroviral exposure, and receipt of methadone therapy. In an intention-to-treat analysis, 79% of DAART participants achieved HIV-1 RNA levels of <400 copies/mL by month 6 of therapy, compared with 54% in the standard care group (P=.035) and 48% in the adherence support group (P=.008). The preliminary results of this study both suggest that DAART can be feasible and acceptable to patients in a methadone clinic setting and provide impetus for further study of this treatment strategy in randomized controlled trials.
