Depression, substance abuse and other contextual predictors of adherence to antiretroviral therapy (ART) among Haitians

Substance Use and Depression Impede ART Adherence Among Female Sex Workers Living with HIV in the Dominican Republic

Female sex workers (FSW) have worse HIV outcomes in part due to lower anti-retroviral therapy (ART) adherence. Substance use and depression are important barriers to ART adherence, yet few studies have assessed these relationships among FSW in longitudinal studies. Cross-Lagged Panel Models and autoregressive mediation analyses assessed substance use (illicit drug use and alcohol use disorders) in relation to ART non-adherence and the mediation role of depressive symptoms among 240 FSW living with HIV in the Dominican Republic. In annual visits (T1, T2, T3), the majority (70%, 66%, and 53%) reported at-risk drinking and 15%, 13% and 9% used illicit drug during the past 6 months. Most FSW (70%, 62% and 46%) had mild-to-severe depression. Illicit drug use predicted later ART non-adherence. This relationship was not mediated via depressive symptoms. Integrated substance use and HIV care interventions are needed to promote ART adherence and viral suppression among FSW.

Factors Associated with Adherence to Treatment in Patients with HIV and Diabetes Mellitus

We aim to identify the factors that influence the therapeutic adherence of subjects with chronic disease. The design followed in this work was empirical, not experimental, and cross-sectional with a correlational objective. The sample consisted of a total of 400 subjects (199 patients with HIV and 201 patients with diabetes mellitus). The instruments applied for data collection were a sociodemographic data questionnaire, the 4-item Morisky Medication Adherence Scale (MMAS-4) and the Coping Strategies Questionnaire. In the group of subjects with HIV, that the use of emotional coping strategies was related to lower adherence to treatment. On the other hand, in the group of subjects with diabetes mellitus, the variable related to compliance with treatment was the duration of illness. Therefore, the predictive factors of adherence to treatment were different in each chronic pathology. In the group of subjects with diabetes mellitus, this variable was related to the duration of the disease. In the group of subjects with HIV, the type of coping strategy used predicted adherence to treatment. As a result of these results, it is possible to develop health programmes to promote, from nursing consultations to adherence to treatment of patients with HIV and diabetes mellitus.

Intimate partner violence and HIV treatment adherence in urban South Africa: Mediating role of perinatal common mental disorders

Background

Antiretroviral therapy (ART) has potential to eliminate perinatal HIV infections, but adherence to ART in late pregnancy and postpartum is often suboptimal. Intimate partner violence (IPV) may influence non-adherence among perinatal women living with HIV (WWH), but few quantitative studies have examined this over time or explored mechanisms for this association.

Methods

We used secondary data from a parent trial in Johannesburg comprising WWH from the control arm (n=63) and WWH ineligible for the trial (n=133). Trained nurse researchers administered questionnaires at first antenatal visit on past-year psychological, physical, and/or sexual IPV (WHO instrument), socio-demographics (age, food security, education), and perinatal common mental symptoms of depression (Hospital Anxiety and Depression Screener-d); anxiety (HADS-a); post-traumatic stress disorder (PTSD; Harvard Trauma Questionnaire). At endline visit 2-4 months postpartum, nurse researchers assessed self-reported ART adherence using a visual analog scale (with ≥95% considered "good"). We fitted structural equation models (SEM) in MPlus to explore direct and indirect effects of IPV on ART adherence.

Results

Of 196 perinatal WWH, 53.1% reported IPV exposure at baseline. The majority of participants (85.7%) had good perinatal ART adherence. In adjusted models, IPV at baseline was associated with halved odds of good adherence (aOR=0.51, 95%CI=0.20-0.96). IPV was associated with higher adjusted odds of probable depression (aOR=4.64), anxiety (aOR=2.85), and PTSD (aOR=3.42). In SEM, IPV had a direct (standardized coef=-0.22) and indirect effect (coef=-0.05) on ART via common mental disorders. The total effect of IPV on perinatal adherence was of moderate size (coef= -0.27) and the model had good fit (CFI=0.972; TLI=0.969; RMSEA=0.045; SRMR=0.076).

Conclusion

IPV was longitudinally associated with perinatal ART non-adherence in part due to its relationship with mental health symptomology. Addressing IPV within clinical care has potential to improve perinatal mental health, maternal HIV outcomes, and HIV-free infant survival.

Perceived Barriers to HIV Care and Viral Suppression Comparing Newly Diagnosed Women Living with HIV in Rural Uganda with and without a History of Intimate Partner Violence

Intimate partner violence (IPV) is associated with poor HIV care linkage and retention, medication adherence, and viral suppression. However, limited knowledge exists regarding potential mechanisms linking IPV to these outcomes. We aimed to (a) identify the top barriers to accessing HIV care experienced by women living with HIV (WLHIV) who report a history of IPV and have suppressed viral load (VL) versus unsuppressed VL and (b) understand how these barriers influence VL, comparing WLHIV with a history of IPV to WLHIV without a history of IPV. Study data come from newly diagnosed WLHIV in rural Uganda participating in the standard-of-care control arm of a randomized trial (n = 152). Descriptive results ranking mean scores from highest to lowest showed that, among women with a history of IPV, irrespective of viral suppression status, paying for transportation to come to clinic, having to wait at the clinic for long periods of time, and finding a clinic within reasonable travel distance were the top three barriers to accessing HIV care. WLHIV with a history of IPV were significantly more likely to have unsuppressed VL versus suppressed VL if they reported higher levels of difficulty finding a clinic within reasonable travel distance (RRR = 1.7, 95% CI [1.1-2.7]), getting permission to take time off from work (RRR = 1.5, 95% CI [1.0-2.9]), and finding time to come to the clinic for an appointment (RRR = 1.6, 95% CI [1.0-2.6]). The same relationships were not present among WLHIV without a history of IPV, suggesting these barriers and their effect on VL may be uniquely related to IPV. Interventions should address IPV and HIV care continuum outcomes in tandem, targeting barriers to accessing HIV care likely associated with IPV. Additional research is necessary to better understand how IPV relates to HIV care barriers and VL.

Association Between ART Adherence and Mental Health: Results from a National HIV Sero-Behavioural Survey in South Africa

This paper assesses the levels of antiretroviral treatment (ART) adherence and mental health distress among study participants in a national behavioural HIV-sero prevalence study South Africa. The study was a cross-sectional population-based multi-stage stratified cluster random survey, (SABSSM V, 2017). Structured questionnaires were used to collect information on socio-demographics, HIV knowledge, perceptions, HIV testing and HIV treatment history. Study participants were tested for HIV infection, antiretroviral use, viral suppression, and ART drug resistance. A total of 2155 PLHIV aged 15 years or older who were on ART were included in the study. Incidence of either moderate or severe mental health distress was 19.7%. Self-reported ART adherence among study participants with no, mild, moderate, or severe mental distress was 82%, 83%, 86% and 78%, respectively. The adjusted odds ratio for ART non-adherence was 0.58 (95% CI 0.24; 1.40) for mild mental distress, 0.82 (95% CI 0.35; 1.91) for moderate mental distress and 2.19 (95% CI 1.14; 4.19) for severe mental distress groups compared to the no mental health distress group. The other factors that were associated with ART non-adherence in adjusted models included education level, alcohol use and province/region of residence. The study revealed that mental health remains a challenge to ART adherence in South Africa. To improve ART adherence, HIV continuum of care programs should include screening for mental health among people living with HIV.

A conceptual model of alcohol use and adherence to antiretroviral therapy: systematic review and theoretical implications for mechanisms of action

Alcohol consumption is one of the most prevalent correlates of antiretroviral therapy (ART) adherence, yet causal processes underlying this association remain largely unexplored. The goal of this systematic review was to develop a conceptual model that describes the causal effect of alcohol consumption on ART nonadherence. We reviewed 230 studies that examined the association between alcohol consumption and ART adherence with three primary aims: (1) to replicate and extend previous reviews of the literature, (2) to summarize and critique study designs capable of answering questions about temporal overlap and (3) to summarize potential mechanisms of action. A model of alcohol-associated ART nonadherence was proposed to guide future work, integrating general theories of ART adherence and theory on the psychological and behavioral effects of alcohol intoxication. The conceptual model describes two mechanistic processes-prospective memory impairment and interactive toxicity beliefs/avoidance behaviors-involved in alcohol-associated intentional and unintentional nonadherence, respectively. This model can be used to guide future research on the causal processes involved in the frequently observed correlation between alcohol consumption and adherence.

The Situated Information, Motivation, and Behavioral Skills Model of HIV Antiretroviral Therapy Adherence Among Persons Living With HIV in Haiti: A Qualitative Study Incorporating Culture and Context

ABSTRACT

To inform a clinic-based adherence-promotion intervention, this qualitative study applied the Situated Information, Motivation, and Behavioral Skills Model of Care Initiation and Maintenance to elucidate cultural and contextual factors affecting antiretroviral therapy adherence in Haiti. From the 23 focus group discussions with patients (n = 58) and health care workers (n = 57), culturally specific themes emerged relating to Information (e.g., conflicts with allopathic medicine and heuristics about how treatment failure occurs), Motivation (e.g., protecting family members, health and physical appearance, material advantages, and relationships with health workers), and Behavioral Skills (e.g., managing food intake and side effects, navigating health services utilization, accessing medication, and advocating for care needs). Recommendations include: provide therapeutic education on HIV drug resistance; promote the concept of "undetectable = untransmittable"; develop treatment buddy relationships; invest in training and enforcement of patient privacy, transparency, and fairness in access to services and resources; and provide patient-centered behavioral skills counseling.

Effect and implementation experience of intensive adherence counseling in a public HIV care center in Uganda: a mixed-methods study

Background

Intensive adherence counseling (IAC) is an intervention recommended by the World Health Organization to improve anti-retroviral therapy (ART) adherence among people living with HIV on ART with unsuppressed viral load; and in 2016, the intervention was implemented in Uganda. This study evaluated the effect and experiences of providing IAC in an urban HIV care center in Kampala, Uganda.

Methods

This was a sequential explanatory mixed-method study that compared viral load suppression during IAC implementation (intervention) to the period before IAC at Kisenyi Health centre IV. Data were abstracted from patient files and viral load register. The effect of IAC on viral load suppression and associated factors were analyzed using modified Poisson regression with robust standard errors. Using in-depth interviews and an inductive analysis approach in Atlas-ti 8. We also explored experiences of providing IAC among healthcare workers.

Results

A total of 500 records were sampled: 249 (49.8%) in the intervention period and 251 (51.2%) in the pre-intervention period. The mean age was lower during the intervention period 33.1 (± 12.0) than 36.5 (± 13.4) in the pre- intervention period, p = 0.002. More clients were currently on Protease-based regimen in the pre-intervention period 179 (71.3%) than 135 (54.2%) in the intervention period, p ≤ 0.001. In the intervention period, all eligible clients received IAC [249/249 (100.0%)]. Overall, 325 (65.0%) received IAC and of these, 143 (44.1%) achieved viral load suppression compared to 46 (26.3%) who received regular counseling. Receiving IAC significantly increased viral load suppression by 22% (aPR 1.22, 95% CI 1.01–1.47). Clients on Protease-based regimen were less likely to suppress than those on Efavirenz or Nevirapine-based regimens (aPR 0.11, 95% CI 0.08–0.15). All the interviewed healthcare workers lauded IAC for improving ART adherence. However, patient and health care system related factors hindered adherence during IAC.

Conclusions

The full potential of IAC in achieving viral load suppression in this setting has not been reached due to a combination of the patient and health care system related factors. Provision of adequate IAC necessities and use of patient centered approach should be emphasized to obtain the maximum benefit of the intervention.

Factors associated with antiretroviral therapy adherence among people living with HIV in Haiti: a cross-sectional study

BACKGROUND

Socioeconomic, demographic and clinical factors can affect adherence to treatment among people living with HIV (PLH) and potentially have an impact on their prognosis and survival. The main objective of this study was to assess these factors as potential barriers to adherence among patients receiving care in central Haiti.

METHODS

A cross-sectional study was conducted among PLH receiving antiretroviral therapy (ART) at the TB/HIV clinic at St. Therese Hospital in Hinche, Haiti. A total of 426 potential participants were approached during their follow-up visits from June to August 2019, of whom 411 participated in the study. After giving informed consent, study participants completed a structured interview that included the Self-Report Item Scale (SRIS), a standard measure, to assess adherence. Socio-demographic, economic and clinical factors were assessed for their association with adherence.

RESULTS

The 411 participating patients represented 39% of the patient population at the TB/HIV clinic during the timeframe of the study. The mean age was 43.7 years (range: 19-80), 65.5% were female and 78.1% had only achieved a primary level of schooling. Nearly 78% had received ART for less than 10 years, 3.41% reported having poor adherence and 28% less than excellent adherence. Factors related to poor adherence in bivariate analysis were age less than 40 years (OR: 6.32, 95% CI 2.04-10.58, p < 0.01) and inability to meet basic needs (OR: 2.70, 95% CI 1.04-7.0, p = 0.03).

CONCLUSIONS

To improve medication adherence, the hospital should strengthen patient counselling of younger recipients of ART and provide financial assistance and other social service interventions. Studies should be implemented in other HIV management centers in Haiti and similar contexts to examine barriers to ART adherence with the goal of improving prognosis and survival in the long-term among PLH in resource-limited setting.

Depressive symptoms among people with HIV/AIDS in Northwest Ethiopia: comparative study

OBJECTIVES

The objective of this study was to compare depressive symptoms among people with HIV/AIDS and the general population sample. We also assessed the factors associated with depressive symptoms.

DESIGN

A comparative cross-sectional study was conducted.

SETTINGS

Antiretroviral therapy clinics in three primary healthcare facilities and semi-urban area in Northwest Ethiopia.

PARTICIPANTS

A total of 1115 participants (558 people with HIV/AIDS and 557 comparison group) aged 18 years and above were recruited. A total of 1026 participants (530 people with HIV/AIDS and 496 comparison group) completed the interview. We excluded people with known HIV-positive status from the comparison group.

OUTCOME MEASURE

Patient Health Questionnaire (PHQ-9) was used to assess depressive symptoms. The proportion of depressive symptoms was compared between samples of the general population and people with HIV/AIDS using χ2 statistics. Multivariable logistic regression analysis was done to examine the associated factors.

RESULTS

The overall prevalence of depressive symptoms was 13.3% (11.2%-15.4%). The prevalence was significantly higher in people with HIV/AIDS compared with the community sample (16.6% vs 12.3%), p=0.001. The difference was also significant in the multivariable logistic regression (OR 1.7). For the overall sample, depressive symptoms were significantly associated with older age, being single, divorced/widowed marital status, and poor social support.

CONCLUSIONS

Depressive symptoms were higher in people with HIV/AIDS compared with the general population. It is necessary to include mental healthcare and screening for depression in routine HIV/AIDS care.

A systematic review of psychosocial interventions for older adults living with HIV

The rapidly growing segment of older adults living with HIV faces unique set of psychosocial challenges that may differ from their younger counterparts. The objective of this review is to systematically examine current published literature on interventions designed to improve the psychosocial wellbeing of older adults living with HIV. A pre-specified search strategy was applied to four databases: PubMed, CINAHL Plus with Text, PsycINFO, and Health Source. Authors reviewed published studies on psychosocial interventions for older adults with HIV and reported psychosocial variables as primary outcomes of the interventions. The final review included nine intervention studies. Psychosocial outcomes measured across multiple studies included depression, quality of life, social support, cognitive functioning, and coping skills. Some studies also measured physical activity, HIV-related discrimination, lack of affordable housing, and access to substance abuse treatment. Our study suggests a paucity of psychosocial intervention research on adults aging with HIV. This review suggests that most psychosocial interventions had small to moderate effects in improving the psychosocial wellbeing of older people living with HIV. Findings highlight the need for clinical, community, and home-based interventions to ensure that individuals can achieve a higher quality of life while aging with HIV.

Gender differences in the association between childhood sexual abuse and risk behaviors among people living with HIV in Haiti

Research shows that in the Caribbean one-third of people living with HIV continue to engage in unprotected sexual practices. Childhood sexual abuse (CSA) and HIV-related risk behaviors have been found to play a contributory role in HIV transmission. We aimed to analyze gender differences in the association between CSA and substance use and sexual risk behaviors among Haitians living with HIV. A total of 276 HIV-positive individuals participated in this study with 56% experiencing sexual abuse during childhood. Results showed that participants who experienced CSA had increased odds of hazardous drinking compared to those who did not experience CSA; men (OR 2.9, 95% CI 1.2-7.3) and women (OR 2.5, 95% CI 1.2-5.6). While, marijuana use was only significantly associated in women (OR 5.2, 95% CI 2.1-13.5). For sexual risk behaviors, unprotected sex was significantly associated in both men (OR 3.0, 95% CI 1.3-7.1) and women (OR 2.0, 95% CI 1.5-7.7) who experienced CSA. Results of this study underscore the need for further research to better understand the role of gender in the relationship between CSA and risky behaviors among PLWH.

The Effects of Childhood Sexual Abuse: The Role of Anxiety and Alcohol Use among Haitian Women Living with HIV

Childhood abuse has been linked to problematic drinking in adulthood. It is also documented that people living with HIV have higher rates of alcohol use than the general population. In Haiti, a total of 25% of women living with HIV have experienced childhood sexual abuse (CSA), which puts them at an increased risk for alcohol abuse. CSA has also been associated with anxiety disorders in adulthood. Therefore, it is critical to understand the relationship between CSA, anxiety, and alcohol use among women living with HIV. A total of 244 women living with HIV participated in this study, with 35% reporting CSA. Alcohol abuse was measured with the AUDIT, anxiety with the State-Trait Anxiety Inventory test, and sexual abuse with the Childhood Trauma Questionnaire. Compared to participants who did not experience childhood sexual abuse, participants who experienced childhood sexual abuse reported greater levels of alcohol use [(17.0, SD = 9.1) (11.9, SD = 8.6) p =.001] and anxiety [(55.8, SD = 9.8) (48.9 SD = 8.3) p =.001] respectively. The indirect effect of anxiety on the association between CSA and alcohol use was significant [(ß =.19 p =.05) 95% bootstrap CI.019 -.13] Thus, women who reported being sexually abused as children reported anxiety, which in turn, was associated with an increased risk for alcohol abuse. Results demonstrate that alcohol may be used as a negative coping mechanism to alleviate anxiety symptoms triggered by CSA. These findings elucidate the need for further research examining the impact that sexual trauma has on mental health.

Assessing the interaction between depressive symptoms and alcohol use prior to antiretroviral therapy on viral suppression among people living with HIV in Rural Uganda

Although there is evidence of individual associations between depressive symptoms and hazardous alcohol use with suboptimal antiretroviral therapy (ART) adherence among people living with HIV (PLWH), few studies have established how the two risk factors may interact to predict viral suppression. We conducted secondary data analyses with two cohorts of Ugandan PLWH (N = 657) to investigate the hypothesized interaction between depressive symptoms (Center for Epidemiological Studies Depression Scale) and hazardous alcohol use (Alcohol Use Disorder Identification Test -Consumption and/or Phosphatidylethanol biomarker) prior to ART initiation with viral suppression (<550 copies/ml). We were unable to detect an interaction between depressive symptoms and hazardous alcohol use prior to ART initiation with viral suppression in the first two years (M = 19.9 months) after ART initiation (p = 0.75). There was also no evidence of a main effect association for depressive symptoms (Adjusted Odds Ratio [AOR] = 0.88, 95% Confidence Interval [CI]: 0.50, 1.55) or hazardous alcohol use (AOR = 1.37, 95% CI: 0.80, 2.33). PLWH with depressive symptoms and/or hazardous alcohol use appear to exhibit similar levels of viral suppression as others in care; further work is needed to determine effects on HIV testing and treatment engagement.

The FANMI ("my FAMILY" in Creole) study to evaluate community-based cohort care for adolescent and young women living with HIV in Haiti: protocol for a randomized controlled trial

BACKGROUND

Adolescent girls and young women living with HIV in resource-limited settings have the poorest health outcomes of any age group, due in part to poor retention in care. Differentiated models of HIV care that target the specific challenges of young people living with HIV are urgently needed.

METHODS

The FANMI study is an unblinded randomized controlled trial designed to evaluate the efficacy of an adolescent-specific model of HIV care in Port-au-Prince, Haiti. The FANMI intervention places newly young women living with HIV who are not currently on ART or on ART ≤ 3 months, in cohorts of 5-10 peers to receive monthly group HIV care in a community location. In contrast, participants in the standard care arm receive routine HIV care and individual counseling each month in GHESKIO's Adolescent Clinic. A total of 160 participants ages 16-23 years old are being randomized on a 1:1 basis. The primary outcome is retention in HIV care defined as being alive and in care at 12 months after enrollment. Secondary outcomes include viral suppression at 12 months, sexual risk behaviors, acceptability of the FANMI intervention, and health care utilization and costs.

DISCUSSION

The FANMI study evaluates a novel community-based cohort model of HIV care aimed at improving retention in care and reducing risk behaviors for HIV transmission among adolescent girls and young women living with HIV. Specifically, the FANMI model of care addresses social isolation by placing participants in cohorts of 5-10 peers to provide intensified peer support and makes HIV health management a group norm; reduces stigma and improves convenience by providing care in a community setting; and integrates clinical care and social support by the same providers to streamline care and promote long-term patient-provider relationships. If shown to be effective, the FANMI intervention may serve as a model of HIV care for improving retention among hard-to-reach adolescents and young adults in Haiti and could be adapted for other high-risk groups globally.

Brief Report: Intimate Partner Violence and Antiretroviral Therapy Initiation Among Female Sex Workers Newly Diagnosed With HIV in Zambia: A Prospective Study

Supplemental Digital Content is Available in the Text.

Background:

Intimate partner violence (IPV) is common among female sex workers (FSW) globally. Here, we prospectively assessed the relationship between IPV and engagement in HIV care in a cohort of FSW who had been newly diagnosed with HIV.

Methods:

Data arose from the Zambian Peer Educators for HIV Self-Testing study, a randomized controlled trial of HIV self-test distribution among FSW in 3 transit towns in Zambia. Participants were self-reported to be HIV-uninfected or unaware of their status at baseline. IPV in the previous 12 months was assessed at baseline. At 4 months, participants were asked the results of their last HIV test and those who reported testing positive were asked whether they had engaged in HIV-related care and started antiretroviral therapy (ART).

Results:

Of 964 participants, 234 (24.3%) reported that they were living with HIV at 4 months. Of these 234 participants, 142 (60.7%) reported a history of IPV (past 12 months) at baseline and at 4 months, 152 (65.0%) reported that they were in HIV-related care, and 132 (56.7%) reported that they had initiated ART. Participants who reported IPV had significantly reduced odds of engagement in care (adjusted odds ratio = 0.48, 95% confidence interval: 0.26 to 0.91) and ART initiation (adjusted odds ratio = 0.40, 95% confidence interval: 0.22 to 0.72).

Conclusions:

FSW living with HIV in Zambia reported very high rates of IPV. Structural and individual interventions for violence prevention are urgently needed to better protect this population. Given the strong negative relationship between IPV and engagement in HIV-related care, such interventions could also substantially improve HIV-related health outcomes.

Adherence to antiretroviral therapy for HIV/AIDS in Latin America and the Caribbean: Systematic review and meta-analysis

INTRODUCTION

Optimal adherence to antiretroviral therapy is closely related with suppression of the HIV viral load in plasma, slowing disease progression and decreasing HIV transmission rates. Despite its importance, the estimated proportion of people living with HIV in Latin America and the Caribbean with optimal adherence has not yet been reported in a meta-analysis. Moreover, little is known of the factors leading to poor adherence which may be setting-specific. We present a pooled estimate of adherence to antiretroviral therapy (ART) of people living with HIV in Latin America and Caribbean, report the methods used to measure adherence and describe the factors associated with poor adherence among the selected studies.

METHODS

We electronically searched published studies up to July 2016 on the PubMed, Web of Science and Virtual Health Library (Latin America and the Caribbean Regional Portal); considering the following databases: MEDLINE, LILACS, PAHO and IBECS. Two independent reviewers selected and extracted data on ART adherence and study characteristics. Pooled estimate of adherence was derived using a random-effects model. Risk of bias in individual studies was assessed independently by two investigators using the Risk of Bias Assessment tool for Non-randomized Studies (RoBANS).

RESULTS AND DISCUSSION

The meta-analysis included 53 studies published between 2005 and 2016, which analysed 22,603 people living with HIV in 25 Latin America and Caribbean countries. Overall adherence in Latin America and Caribbean was 70% (95% CI: 63-76; I²  = 98%), similar to levels identified by studies conducted in high-income regions. Self-report was the most frequently used method to measure adherence. Subgroup analysis showed that adherence was higher for the shortest recall time frame used, as well as in countries with lower income level, Gross National Income (GNI) per capita and Human Development Index (HDI). Studies reported diverse adherence barriers, such as alcohol and substance misuse, depression, unemployment and pill burden.

CONCLUSIONS

Our study suggests that adherence to ART in Latin America and Caribbean may be below the sufficient levels required for a successful long-term viral load suppression.

The Role of Religious Service Attendance, Psychosocial and Behavioral Determinants of Antiretroviral Therapy (ART) Adherence: Results from HPTN 063 Cohort Study

Early and sustained antiretroviral therapy (ART) adherence can suppress the HIV virus in individuals and reduce onward transmission of HIV in the population. Religiosity has been associated with better HIV clinical outcomes. Data are from a longitudinal, observational study of 749 HIV-infected individuals from Brazil, Zambia, and Thailand (HPTN 063). Ordered logistic regression assessed whether religious service attendance was associated with ART adherence (self-reported and plasma HIV-RNA) and moderated the association between alcohol problems and ART adherence. In each country, > 80% of participants reported high self-reported ART adherence (good/very good/excellent). Religious service attendance exceeded 85% but was statistically unrelated to adherence. In combined-country models, (p = 0.03) as alcohol problems increased, the probability of high self-reported ART adherence, as well as viral-load, became weaker at higher compared to low service attendance frequency. Future studies should evaluate spirituality variables and replicate the moderation analyses between religious attendance and alcohol problems.

Harmful alcohol drinking among HIV-positive people in Nepal: an overlooked threat to anti-retroviral therapy adherence and health-related quality of life

Background: People living with Human Immunodeficiency Virus (HIV) often suffer from alcohol-use disorders resulting in their poor health and treatment outcomes. Little is known about the association of harmful alcohol drinking with their adherence to anti-retroviral therapy (ART) and health-related quality of life (QOL) in low-resource settings.

Objective: This study aimed to investigate associations between harmful alcohol drinking, adherence to ART and health-related QOL in HIV-positive people, stratified by gender, in Nepal.

Methods: We conducted a cross-sectional study of 682 HIV-positive people on ART to measure their self-reported harmful alcohol drinking and non-adherence to ART in the previous month of data collection. We also measured health-related QOL using a WHOQOL-HIV BREF scale. The association between harmful alcohol drinking and non-adherence to ART was examined using multiple logistic regressions. Additionally, multiple linear regressions examined association between harmful alcohol drinking and QOL.

Results: Harmful alcohol drinking was associated with non-adherence to ART among men (AOR: 2.48, 95% CI: 1.50, 4.11, p < 0.001) and women (AOR: 2.52, 95% CI: 1.32, 4.80, p = 0.005). Men were more likely to have lower score for the psychological (β = −0.55, p = 0.021) and level of independence (β = −0.68, p = 0.018) domains when they had harmful alcohol drinking. Moreover, women were more likely to have lower scores for the physical (β = −1.01, p = 0.015), social relations (β = −0.82, p = 0.033), environmental (β = −0.88, p = 0.011), and spiritual (β = −1.30, p = 0.005) domains of QOL when they had harmful alcohol drinking.

Conclusions: Harmful alcohol drinking had a negative association with ART adherence and QOL in both HIV-positive men and women in Nepal. Screening for alcohol-use disorders and community-based counseling services should be provided while delivering ART services to improve treatment adherence and QOL.

Violence From a Sexual Partner is Significantly Associated With Poor HIV Care and Treatment Outcomes Among Female Sex Workers in the Dominican Republic

BACKGROUND

Female sex workers (FSWs) experience high rates of violence from their sexual partners. Although violence is associated with HIV risk behaviors among FSWs, there is limited evidence on the association between violence and HIV treatment outcomes.

METHODS

We analyzed data from a socio-behavioral survey with a cohort of FSWs living with HIV in the Dominican Republic (n = 268) to describe the burden of violence from a sexual partner in the last 6 months. We assessed the relationship between violence and HIV treatment outcomes, comparing findings across 2 types of sexual partners: intimate partners and clients.

RESULTS

Nearly one-fifth of women (18.3%) experienced violence in the last 6 months. More women experienced violence from an intimate partner (12.3%) than a client (8.3%), with some (2.6%) reporting both. Although violence from an intimate partner was significantly associated with not currently being on antiretroviral treatment [ART; adjusted odds ratio (AOR): 4.05, 95% confidence interval (CI): 1.00 to 16.36] and missing an ART dose in the last 4 days (AOR: 5.26, 95% CI: 1.91 to 14.53), violence from a client was associated with never having received HIV care (AOR: 2.85, 95% CI: 1.03 to 7.92) and ever interrupting ART (AOR: 5.45, 95% CI: 1.50 to 19.75).

CONCLUSIONS

Violence from a sexual partner is associated with poor HIV treatment outcomes among FSWs. Different patterns by type of partner reflect how relationship dynamics may influence these associations. Violence prevention and support services should be tailored based on type of partner. Violence screening and referrals should be integrated into HIV care services for FSWs to improve their health and reduce ongoing transmission.

Mortality in Children with Human Immunodeficiency Virus Initiating Treatment: A Six-Cohort Study in Latin America

OBJECTIVES

To assess the risks of and factors associated with mortality, loss to follow-up, and changing regimens after children with HIV infected perinatally initiate combination antiretroviral therapy (cART) in Latin America and the Caribbean.

STUDY DESIGN

This 1997-2013 retrospective cohort study included 1174 antiretroviral therapy-naïve, perinatally infected children who started cART age when they were younger than 18 years of age (median 4.7 years; IQR 1.7-8.8) at 1 of 6 cohorts from Argentina, Brazil, Haiti, and Honduras, within the Caribbean, Central and South America Network for HIV Epidemiology. Median follow-up was 5.6 years (IQR 2.3-9.3). Study outcomes were all-cause mortality, loss to follow-up, and major changes in cART. We used Cox proportional hazards models stratified by site to examine the association between predictors and times to death or changing regimens.

RESULTS

Only 52% started cART at younger than 5 years of age; 19% began a protease inhibitor. At cART initiation, median CD4 count was 472 cells/mm³ (IQR 201-902); median CD4% was 16% (IQR 10-23). Probability of death was high in the first year of cART: 0.06 (95% CI 0.04-0.07). Five years after cART initiation, the cumulative mortality incidence was 0.12 (95% CI 0.10-0.14). Cumulative incidences for loss to follow-up and regimen change after 5 years were 0.16 (95% 0.14-0.18) and 0.30 (95% 0.26-0.34), respectively. Younger children had the greatest risk of mortality, whereas older children had the greatest risk of being lost to follow-up or changing regimens.

CONCLUSIONS

Innovative clinical and community approaches are needed for quality improvement in the pediatric care of HIV in the Americas.

Patient Use of Electronic Prescription Refill and Secure Messaging and Its Association With Undetectable HIV Viral Load: A Retrospective Cohort Study

BACKGROUND

Electronic personal health records (PHRs) can support patient self-management of chronic conditions. Managing human immunodeficiency virus (HIV) viral load, through taking antiretroviral therapy (ART) is crucial to long term survival of persons with HIV. Many persons with HIV have difficulty adhering to their ART over long periods of time. PHRs contribute to chronic disease self-care and may help persons with HIV remain adherent to ART. Proportionally veterans with HIV are among the most active users of the US Department of Veterans Affairs (VA) PHR, called My HealtheVet. Little is known about whether the use of the PHR is associated with improved HIV outcomes in this population.

OBJECTIVE

The objective of this study was to investigate whether there are associations between the use of PHR tools (electronic prescription refill and secure messaging [SM] with providers) and HIV viral load in US veterans.

METHODS

We conducted a retrospective cohort study using data from the VA's electronic health record (EHR) and the PHR. We identified veterans in VA care from 2009-2012 who had HIV and who used the PHR. We examined which ones had achieved the positive outcome of suppressed HIV viral load, and whether achievement of this outcome was associated with electronic prescription refill or SM. From 18,913 veterans with HIV, there were 3374 who both had a detectable viral load in 2009 and who had had a follow-up viral load test in 2012. To assess relationships between electronic prescription refill and viral control, and SM and viral control, we fit a series of multivariable generalized estimating equation models, accounting for clustering in VA facilities. We adjusted for patient demographic and clinical characteristics associated with portal use. In the initial models, the predictor variables were included in dichotomous format. Subsequently, to evaluate a potential dose-effect, the predictor variables were included as ordinal variables.

RESULTS

Among our sample of 3374 veterans with HIV who received VA care from 2009-2012, those who had transitioned from detectable HIV viral load in 2009 to undetectable viral load in 2012 tended to be older (P=.004), more likely to be white (P<.001), and less likely to have a substance use disorder, problem alcohol use, or psychosis (P=.006, P=.03, P=.004, respectively). There was a statistically significant positive association between use of electronic prescription refill and change in HIV viral load status from 2009-2012, from detectable to undetectable (OR 1.36, CI 1.11-1.66). There was a similar association between SM use and viral load status, but without achieving statistical significance (OR 1.28, CI 0.89-1.85). Analyses did not demonstrate a dose-response of prescription refill or SM use for change in viral load.

CONCLUSIONS

PHR use, specifically use of electronic prescription refill, was associated with greater control of HIV. Additional studies are needed to understand the mechanisms by which this may be occurring.

Healthy Aging in Older Women Living with HIV Infection: a Systematic Review of Psychosocial Factors

Due to life-enhancing effects of antiretroviral therapy, HIV-positive persons have the potential for long life comparable to their uninfected peers. Older women (age 50+) living with HIV (OWLH) are often an under-recognized aging group. We conducted a systematic review to examine psychosocial factors that impact how OWLH live, cope, and age with HIV. Initial key word search yielded 1527 records, and 21 studies met our inclusion criteria of original quantitative or qualitative research published between 2013 and 2016 with results specific to OWLH. These focused on health care and self-management, sexual health and risk, stigma, loneliness, mental health (depression, substance use), and protective factors (coping, social support, well-being). Due to the scarcity of studies on each topic and inconclusive findings, no clear patterns of results emerged. As the number of OWLH continues to grow, more research, including longitudinal studies, is needed to fully characterize the psychosocial factors that impact aging with HIV.

Antiretroviral Adherence Perspectives of Pregnant and Postpartum Women in Guyana

The Caribbean region has the second highest HIV prevalence after Sub-Saharan Africa. Guyana's adult HIV prevalence is 1.9% among pregnant women, with women accounting for an estimated 58% of all persons living with HIV. However, there are few studies on ART adherence in the Caribbean, none from Guyana, and none focusing on adherence in pregnancy and the postpartum period. The objective of this study was to explore the perspectives of HIV-infected pregnant and postpartum women and healthcare providers in Guyana about barriers and facilitators to ART adherence. Data was collected using semi-structured interviews with 24 HIV-infected pregnant and postpartum women and nine healthcare professionals at five clinics between February and April 2012. The Framework Method for analysing qualitative data identified facilitators and barriers related to five core themes: (i) Concern for wellbeing of children; (ii) ART-related factors; (iii) Disclosure; (iv) Socio-economic issues; and (v) Religious and cultural beliefs. Non-disclosure did not adversely affect adherence, contrary to other studies in the literature. Two broad categories emerged from the lived experiences of women in Guyana. The first is related to the act of actually taking their medication where their tenacity is displayed in efforts made to ensure ART is taken. The second relates to the significance of ART to them in terms of reduced risk of MTCT, and the possibility of better health for themselves to enable them to care for their children. However, issues related to poverty, food insecurity and side effects reduced adherence need to be adequately addressed.

Mechanisms linking intimate partner violence and prevention of mother-to-child transmission of HIV: A qualitative study in South Africa

Prevention of mother-to-child transmission (PMTCT) can virtually eliminate HIV infection among infants, yet up to one-third of women miss PMTCT steps. Little is known about how partner dynamics such as intimate partner violence (IPV) influence pregnant and postpartum women's adherence to PMTCT. We conducted 32 qualitative interviews with HIV-positive pregnant and postpartum women in Johannesburg who experienced IPV. Trained researchers conducted in-depth interviews over the period of May 2014-Nov 2015 using narrative and social constructionist approaches. Interviews were transcribed verbatim and analyzed thematically and inductively using Dedoose qualitative software. Twenty-six women experienced recent IPV and one-third had poor adherence to PMTCT. Women's experience of partner violence influenced PMTCT behaviors through four pathways. First, fear of partner disclosure led some women to hide their HIV status to avoid a violent reaction. Despite strategic non-disclosure, several maintained good adherence by hiding medication or moving out from their partner's home. Second, IPV caused feelings of depression and anxiety that led to intentionally or accidentally missing medication. Five women stopped treatment altogether, in a type of passive suicidality, hoping to end the distress of IPV. Third, men's controlling behaviors reduced access to friends and family, limiting social support needed for good adherence. Fourth, in a protective pathway, women reported good adherence partly due to their mothering role. The identity around motherhood was used as a coping technique, reminding women that their infant's wellbeing depended on their own health. PMTCT is essential to prevent vertical HIV transmission, but women living with IPV face multiple pathways to non-adherence. Addressing IPV in antenatal care can support the health of women and infants and may enhance PMTCT coverage.

Predicting adherence to antiretroviral therapy among pregnant women in Guyana: Utility of the Health Belief Model

Barriers to antiretroviral therapy (ART) adherence among pregnant women are varied and complex. This study explored the constructs of a theoretical model, the Health Belief Model (HBM) to understand and predict ART adherence among pregnant women in Guyana. A cross-sectional study surveyed 108 pregnant women attending 11 primary care clinics. ART adherence ranging from the past weekend to three months was assessed through self-reports, and health beliefs with the Adherence Determinants Questionnaire (ADQ). Constructs with sufficient variation in responses were tested for association with the level of adherence using Spearman's rank correlation coefficient and test. Sixty-seven per cent (72) of the women reported being always adherent. Although there was positive endorsement of ART treatment and adherence, the HBM did not help in understanding or predicting ART adherence in this population. Only one item from the perceived susceptibility construct was significantly associated (p = 0.009) with adherence. Interventions are warranted to address ART adherence in this population, as 19% of the women were recently non-adherent. Although the ADQ did not contribute to a deeper understanding or provide insight into pathways that can be targeted for intervention, theoretical models can play a key role in identifying these pathways.

Optimal Treatment Adherence Counseling Outcomes for People Living with HIV and Limited Health Literacy

Limited health literacy has been shown to contribute to poor adherence to antiretroviral therapy (ART) in people living with HIV/AIDS. Given the mixed results of previous interventions for people with HIV and low health literacy, investigating possible targets for improved adherence is warranted. The present study aims to identify the correlates of optimal and suboptimal outcomes among participants of a recent skills-based medication adherence intervention. This secondary analysis included 188 men and women living with HIV who had low health literacy and who had complete viral load data. Adherence was assessed by unannounced pill count and follow-up viral loads were assessed by blood draw. Results showed that higher levels of health literacy and lower levels of alcohol use were the strongest predictors of achieving HIV viral load optimal outcomes. The interplay between lower health literacy and alcohol use on adherence should be the focus of future research.

Barriers to HIV Medication Adherence: Examining Distinct Anxiety and Depression Symptoms among Women Living with HIV Who Experienced Childhood Sexual Abuse

Experiencing sexual violence in childhood or adolescence is highly prevalent among some women living with HIV, often resulting in anxiety and depression symptoms in adulthood. Anxiety and depression have been associated with HIV medication nonadherence, yet little research has assessed distinct components of anxiety and depression as risk factors of HIV medication nonadherence. The current study examined distinct symptom components of anxiety and depression as predictors of HIV medication non-adherence among women living with HIV and childhood sexual abuse enrolled in a coping intervention. This secondary analysis included a sample of 85 women living with HIV and childhood sexual abuse and being prescribed antiretroviral medication who completed measures on anxiety, depression, and medication adherence. Results from a logistic regression analysis suggest that distinct components of anxiety may be related to medication nonadherence among this population. Targeted mental health interventions for this population may increase adherence to antiretroviral medication.

[Poor quality of sleep associated with low adherence to highly active antiretroviral therapy in Peruvian patients with HIV/AIDS]

This cross-sectional study analyzed the association between poor quality of sleep and adherence to highly active antiretroviral therapy (HAART) in 389 Peruvian patients with HIV/AIDS. Poor quality of sleep was measured with the Pittsburgh Sleep Quality Index (PSQI) and adherence with the CEAT-VIH (Peruvian adaptation). A Poisson generalized linear model with robust standard errors was used to estimate prevalence ratios and 95%CI. A crude model showed that mild, moderate, and severe poor quality of sleep were associated with inadequate treatment adherence. In the adjusted model for variables associated in the bivariate analysis or variables theoretically associated with adherence, only moderate/severe poor quality of sleep remained associated (PR = 1.34, 95%CI: 1.17-1.54; and PR = 1.34, 95%CI: 1.16-1.57, respectively). The study concluded that moderate/severe poor quality of sleep was independently associated with adherence to HAART. Assessing quality of sleep may be helpful in the comprehensive evaluation of HIV patients.

Intimate partner violence and engagement in HIV care and treatment among women: a systematic review and meta-analysis

OBJECTIVE

We aimed to estimate the odds of engagement in HIV care and treatment among HIV-positive women reporting intimate partner violence (IPV).

DESIGN

We systematically reviewed the literature on the association between IPV and engagement in care. Data sources included searches of electronic databases (PubMed, Web of Science, CINAHL and PsychoInfo), hand searches and citation tracking.

METHODS

Two reviewers screened 757 full-text articles, extracted data and independently appraised study quality. Included studies were peer-reviewed and assessed IPV alongside engagement in care outcomes: antiretroviral treatment (ART) use; self-reported ART adherence; viral suppression; retention in HIV care. Odds ratios (ORs) were pooled using random effects meta-analysis.

RESULTS

Thirteen cross-sectional studies among HIV-positive women were included. Measurement of IPV varied, with most studies defining a 'case' as any history of physical and/or sexual IPV. Meta-analysis of five studies showed IPV to be significantly associated with lower ART use [OR 0.79, 95% confidence interval (95% CI) 0.64-0.97]. IPV was associated with poorer self-reported ART adherence in six studies (OR 0.48, 95% CI 0.30-0.75) and lower odds of viral load suppression in seven studies (OR 0.64, 95% CI 0.46-0.90). Lack of longitudinal data and measurement considerations should temper interpretation of these results.

CONCLUSION

IPV is associated with lower ART use, half the odds of self-reported ART adherence and significantly worsened viral suppression among women. To ensure the health of HIV-positive women, it is essential for clinical programmes to address conditions that impact engagement in care and treatment. IPV is one such condition, and its association with declines in ART use and adherence requires urgent attention.

The interaction of active substance use, depression, and antiretroviral adherence in methadone maintenance

BACKGROUND

Adherence to highly active antiretroviral therapy (HAART) remains crucial in successfully treating HIV. While active substance use and depression are both associated with each other and with HAART nonadherence, little is known about their interaction. An understanding of the interaction of substance use and depressive symptoms on HAART adherence can inform adherence-enhancing interventions as well as interventions that target substance use and depression.

PURPOSE

We tested an interaction between substance use and depression on HAART adherence among methadone maintenance patients.

METHOD

We assessed substance use, depressive symptoms, and HAART adherence among 100 HIV-infected individuals receiving methadone maintenance in The Bronx, New York. Regressions were performed on adherence using an interaction term comprised of substance use and depressive symptoms. MODPROBE was used to assess significant interactions.

RESULTS

Any use of illicit substances was associated with HAART nonadherence (p = 0.043). Cannabis was the single substance of abuse most strongly associated with nonadherence (p = 0.003). Depressive symptoms approached significance in bivariate analysis (p = 0.066). In regression analysis, a significant interaction was found between illicit substance use and depressive symptoms [OR (95% CI) 1.23 (1.06-1.44), p = 0.007], where illicit substance use was associated with nonadherence in individuals with lower depressive symptoms, but not among those with depressive symptoms at higher levels. No individual substances interacted with depressive symptoms on adherence.

CONCLUSION

Though substance use and depressive symptoms interacted on HAART adherence, they did not have a synergistic effect. Continued substance use (51% of the sample) suggests an unmet need for treatment, even in methadone maintenance. Further examinations of the interplay of substance use and depression on HAART adherence are warranted.

Adherence to Early Antiretroviral Therapy: Results From HPTN 052, a Phase III, Multinational Randomized Trial of ART to Prevent HIV-1 Sexual Transmission in Serodiscordant Couples

BACKGROUND

Combination antiretroviral therapy (ART) for HIV-1-infected individuals prevents sexual transmission if viral load is suppressed.

METHODS

Participants were HIV-1-infected partners randomized to early ART (CD4 350-550) in HPTN052 (n = 886, median follow-up = 2.1 years), a clinical trial of early ART to prevent sexual transmission of HIV-1 in serodiscordant couples at 13 sites in 9 countries. Adherence was assessed through pill count (dichotomized at <95%) and through self-report items. Predictors of adherence were mental health and general health perceptions, substance use, binge drinking, social support, sexual behaviors, and demographics. Viral suppression was defined as HIV plasma viral load <400 copies per milliliter. Adherence counseling and couples' counseling about safer sex were provided. Logistic and linear regression models using generalized estimating equation for repeated measurements were used.

FINDINGS

Through pill count, 82% of participants were adherent at 1 month and 83.3% at 1 year. Mental health was the only psychosocial variable associated with adherence [pill count, odds ratios (OR) = 1.05, 95% confidence intervals (CIs): 1.00 to 1.11; self-report parameter estimate, OR = 0.02, 95% CI: 0.01 to 0.04], although regional differences emerged. Pill count (OR = 1.19, 95% CI: 1.10 to 1.30) and self-report (OR = 1.42, 95% CI: 1.14 to 1.77) adherence were associated with viral suppression.

INTERPRETATION

Although adherence was high among individuals in stable relationships taking ART for prevention, mental health and adherence covaried. Assessing and intervening on mental health in the context of promoting adherence to ART as prevention should be explored. Adherence and couples' counseling, feedback about viral suppression, and/or altruism may also help explain the magnitude of adherence observed.

Depression and Apathy Among People Living with HIV: Implications for Treatment of HIV Associated Neurocognitive Disorders

Depression and apathy are common among people living with HIV (PLWH). However, in PLWH, it is unclear whether depression and apathy are distinct conditions, which contribute to different patterns of disruption to cognitive processing and brain systems. Understanding these conditions may enable the development of prognostic indicators for HIV associated neurocognitive disorders (HAND). The present study examined substance use behavior and cognitive deficits, associated with depression and apathy, in 120 PLWH, using hierarchical regression analyses. Higher levels of depression were associated with a history of alcohol dependence and greater deficits in processing speed, motor and global cognitive functioning. Higher levels of apathy were associated with a history of cocaine dependence. It is recommended that PLWH get screened appropriately for apathy and depression, in order to receive the appropriate treatment, considering the comorbidities associated with each condition. Future research should examine the neurological correlates of apathy and depression in PLWH.

Disclosure of their HIV status to perinatally infected youth using the adapted Blasini disclosure model in Haiti and the Dominican Republic: preliminary results

OBJECTIVES

To assess the safety, acceptability, and preliminary efficacy of a culturally-adapted disclosure intervention for perinatally HIV-infected combined antiretroviral therapy patients in Haiti and the Dominican Republic.

DESIGN

A quasi-experimental trial was conducted comparing caregiver-youth pairs who completed the intervention [adapted Blasini disclosure model (aBDM)] to pairs who discontinued aBDM participation before disclosure. aBDM consists of five components: structured healthcare worker training; one-on one pre-disclosure intervention/education sessions for youth (describing pediatric chronic diseases including cancer, diabetes and HIV) and for caregivers (strengthening capacity for disclosure); a scheduled supportive disclosure session; and one-on-one postdisclosure support for caregivers and youth.

METHODS

Caregivers of nondisclosed combined antiretroviral therapy patients aged 10.0-17.8 years were invited to participate. Data were collected by separate one-on-one face-to-face interviews of caregivers and youth by study staff and medical record review by pediatricians at enrollment and 3 months after disclosure or after intervention discontinuation.

RESULTS

To date, 65 Dominican Republic and 27 Haiti caregiver-youth pairs have enrolled. At enrollment, only 46.4% of youth had viral suppression and 43.4% of caregivers had clinically significant depressive symptomatology. To date, two serious study-related adverse events have occurred. Seven of the 92 (7.6%, 6 in the Dominican Republic) enrolled pairs discontinued participation before disclosure and 39 had completed postdisclosure participation. Median plasma HIV-RNA concentration was lower in youth who completed aBDM than in youth who discontinued participation before aBDM disclosure (<40 versus 8673 copies/ml; P = 0.027). Completers expressed considerable satisfaction with aBDM.

CONCLUSION

Preliminary results suggest safety, acceptability, and possible effectiveness of the aBDM.

Depression in caregivers of status-naïve pediatric HIV patients participating in a status disclosure study in Haiti and the Dominican Republic: preliminary report

A pilot study is underway to assess safety and acceptability of an intervention to disclose their HIV infection status to status-naïve pediatric antiretroviral therapy patients in Hispaniola [the island shared by Haiti and the Dominican Republic (DR)]. Of 22 Haiti and 47 DR caregivers recruited to date, 68.2% Haiti and 34.0% DR caregivers had clinically significant depressive symptomatology at the time of enrollment (p = 0.008). Depressive symptom prevalence was higher in Haiti caregivers who were female (81.3% vs. 0 in males; p = 0.02) and in DR caregivers who were patients' mothers (50.0%) or grandmothers (66.7%; 56.0% combined) than others (9.1%), (p < 0.001). Internalized stigma was more commonly reported by Haiti (85.7%) than DR (53.2%; p = 0.01) caregivers; 56.4% of Haiti and DR caregivers reporting internalized stigma vs. 26.1% of caregivers denying it had depressive symptoms (p = 0.02). Depression is common in Hispaniola caregivers possibly affecting disclosure timing. Study participation presents opportunities for addressing caregiver depression.

Reliability and validity of a single-item rating scale to monitor medication adherence for people living with HIV and lower health literacy

BACKGROUND

Monitoring medication adherence in clinical and research settings may be especially challenging for people with lower literacy skills.

OBJECTIVE

The current study examined the measurement properties of a single-item rating scale (SIRS) for assessing medication adherence in a sample of 468 people living with HIV and lower health literacy skills.

METHODS

Participants completed two versions (computerized and telephone interview) of an SIRS as well as unannounced monthly pill counts. We also collected measures of common correlates of adherence and obtained participants' HIV RNA viral load from medical records.

RESULTS

Results indicated that the SIRS is time stable over one month (r = 0.46 to 0.52). There was limited evidence for modality effects between the computerized and phone administered SIRS. Associations with unannounced pill counts demonstrated concurrent and predictive validity of the SIRS, and criterion-related validity by associations with viral load. However, the SIRS also demonstrated inflated adherence estimates relative to unannounced pill counts and these discrepancies were greatest for persons of lower income and who reported alcohol use.

CONCLUSIONS

A simple SIRS to monitor medication adherence may therefore be reliable and valid for use with people challenged by lower literacy skills in both clinical and research settings.

Bidirectional links between HIV and intimate partner violence in pregnancy: implications for prevention of mother-to-child transmission

Introduction

Prevention of mother-to-child transmission (PMTCT) has the potential to eliminate new HIV infections among infants. Yet in many parts of sub-Saharan Africa, PMTCT coverage remains low, leading to unacceptably high rates of morbidity among mothers and new infections among infants. Intimate partner violence (IPV) may be a structural driver of poor PMTCT uptake, but has received little attention in the literature to date.

Methods

We conducted qualitative research in three Johannesburg antenatal clinics to understand the links between IPV and HIV-related health of pregnant women. We held focus group discussions with pregnant women (n=13) alongside qualitative interviews with health care providers (n=10), district health managers (n=10) and pregnant abused women (n=5). Data were analysed in Nvivo10 using a team-based approach to thematic coding.

Findings

We found qualitative evidence of strong bidirectional links between IPV and HIV among pregnant women. HIV diagnosis during pregnancy, and subsequent partner disclosure, were noted as a common trigger of IPV. Disclosure leads to violence because it causes relationship conflict, usually related to perceived infidelity and the notion that women are “bringing” the disease into the relationship. IPV worsened HIV-related health through poor PMTCT adherence, since taking medication or accessing health services might unintentionally alert male partners of the women's HIV status. IPV also impacted on HIV-related health via mental health, as women described feeling depressed and anxious due to the violence. IPV led to secondary HIV risk as women experienced forced sex, often with little power to negotiate condom use. Pregnant women described staying silent about condom negotiation in order to stay physically safe during pregnancy.

Conclusions

IPV is a crucial issue in the lives of pregnant women and has bidirectional links with HIV-related health. IPV may worsen access to PMTCT and secondary prevention behaviours, thereby posing a risk of secondary transmission. IPV should be urgently addressed in antenatal care settings to improve uptake of PMTCT and ensure that goals of maternal and child health are met in sub-Saharan African settings.

The examination of emotion dysregulation as a moderator of depression and HIV-relevant outcome relations among an HIV+sample

The present study examined whether emotion dysregulation moderated the relations between depressive symptoms and HIV symptoms, HIV medication adherence due to medication side effects, avoidant coping, and distress tolerance among people living with HIV/AIDS (PLHA). Participants included 115 PLHA (16.8% female; Mage = 49.70, SD = 8.57). Results indicated that there was a significant interaction between depressive symptoms and emotion dysregulation in relation to HIV symptoms, HIV medication adherence due to medication side effects, avoidant coping, and distress tolerance. The form of the interaction indicated that PLHA experiencing higher depressive symptoms and higher levels of emotion dysregulation reported the highest levels of HIV symptoms and lowest levels of distress tolerance. Additionally, results indicated that at lower levels of depressive symptoms, very high levels of emotion dysregulation predicted higher rates of medication nonadherence, whereas at higher levels of depressive symptoms, very high levels of emotion dysregulation predicted the lowest rates of medication nonadherence. Moreover, those experiencing lower levels of depressive symptoms and higher levels of emotion dysregulation reported the greatest rates of avoidant coping. In total, the present results suggest a complex interplay between emotion dysregulation and depressive symptoms with regard to HIV symptoms, medication nonadherence, and self-regulatory processes (e.g., avoidant coping, distress tolerance) among PLHA.

Psychosocial predictors of non-adherence and treatment failure in a large scale multi-national trial of antiretroviral therapy for HIV: data from the ACTG A5175/PEARLS trial

Background

PEARLS, a large scale trial of antiretroviral therapy (ART) for HIV (n = 1,571, 9 countries, 4 continents), found that a once-daily protease inhibitor (PI) based regimen (ATV+DDI+FTC), but not a once-daily non-nucleoside reverse transcriptase inhibitor/nucleoside reverse transcriptase inhibitor (NNRTI/NRTI) regimen (EFV+FTC/TDF), had inferior efficacy compared to a standard of care twice-daily NNRTI/NRTI regimen (EFV+3TC/ZDV). The present study examined non-adherence in PEARLS.

Methods

Outcomes: non-adherence assessed by pill count and by self-report, and time to treatment failure. Longitudinal predictors: regimen, quality of life (general health perceptions  =  QOL-health, mental health  =  QOL-mental health), social support, substance use, binge drinking, and sexual behaviors. “Life-Steps” adherence counseling was provided.

Results

In both pill-count and self-report multivariable models, both once-a-day regimens had lower levels of non-adherence than the twice-a-day standard of care regimen; although these associations attenuated with time in the self-report model. In both multivariable models, hard-drug use was associated with non-adherence, living in Africa and better QOL-health were associated with less non-adherence. According to pill-count, unprotected sex was associated with non-adherence. According to self-report, soft-drug use was associated with non-adherence and living in Asia was associated with less non-adherence. Both pill-count (HR = 1.55, 95% CI: 1.15, 2.09, p<.01) and self-report (HR = 1.13, 95% CI: 1.08, 1.13, p<.01) non-adherence were significant predictors of treatment failure over 72 weeks. In multivariable models (including pill-count or self-report nonadherence), worse QOL-health, age group (younger), and region were also significant predictors of treatment failure.

Conclusion

In the context of a large, multi-national, multi-continent, clinical trial there were variations in adherence over time, with more simplified regimens generally being associated with better adherence. Additionally, variables such as QOL-health, regimen, drug-use, and region play a role. Self-report and pill-count adherence, as well as additional psychosocial variables, such QOL-health, age, and region, were, in turn, associated with treatment failure.

Predictors and correlates of adherence to combination antiretroviral therapy (ART) for chronic HIV infection: a meta-analysis

BACKGROUND

Adherence to combination antiretroviral therapy (ART) is a key predictor of the success of human immunodeficiency virus (HIV) treatment, and is potentially amenable to intervention. Insight into predictors or correlates of non-adherence to ART may help guide targets for the development of adherence-enhancing interventions. Our objective was to review evidence on predictors/correlates of adherence to ART, and to aggregate findings into quantitative estimates of their impact on adherence.

METHODS

We searched PubMed for original English-language papers, published between 1996 and June 2014, and the reference lists of all relevant articles found. Studies reporting on predictors/correlates of adherence of adults prescribed ART for chronic HIV infection were included without restriction to adherence assessment method, study design or geographical location. Two researchers independently extracted the data from the same papers. Random effects models with inverse variance weights were used to aggregate findings into pooled effects estimates with 95% confidence intervals. The standardized mean difference (SMD) was used as the common effect size. The impact of study design features (adherence assessment method, study design, and the United Nations Human Development Index (HDI) of the country in which the study was set) was investigated using categorical mixed effects meta-regression.

RESULTS

In total, 207 studies were included. The following predictors/correlates were most strongly associated with adherence: adherence self-efficacy (SMD = 0.603, P = 0.001), current substance use (SMD = -0.395, P = 0.001), concerns about ART (SMD = -0.388, P = 0.001), beliefs about the necessity/utility of ART (SMD = 0.357, P = 0.001), trust/satisfaction with the HIV care provider (SMD = 0.377, P = 0.001), depressive symptoms (SMD = -0.305, P = 0.001), stigma about HIV (SMD = -0.282, P = 0.001), and social support (SMD = 0.237, P = 0.001). Smaller but significant associations were observed for the following being prescribed a protease inhibitor-containing regimen (SMD = -0.196, P = 0.001), daily dosing frequency (SMD = -0.193, P = 0.001), financial constraints (SMD -0.187, P = 0.001) and pill burden (SMD = -0.124, P = 0.001). Higher trust/satisfaction with the HIV care provider, a lower daily dosing frequency, and fewer depressive symptoms were more strongly related with higher adherence in low and medium HDI countries than in high HDI countries.

CONCLUSIONS

These findings suggest that adherence-enhancing interventions should particularly target psychological factors such as self-efficacy and concerns/beliefs about the efficacy and safety of ART. Moreover, these findings suggest that simplification of regimens might have smaller but significant effects.

Predictors and correlates of adherence to combination antiretroviral therapy (ART) for chronic HIV infection: a meta-analysis

Background

Adherence to combination antiretroviral therapy (ART) is a key predictor of the success of human immunodeficiency virus (HIV) treatment, and is potentially amenable to intervention. Insight into predictors or correlates of non-adherence to ART may help guide targets for the development of adherence-enhancing interventions. Our objective was to review evidence on predictors/correlates of adherence to ART, and to aggregate findings into quantitative estimates of their impact on adherence.

Methods

We searched PubMed for original English-language papers, published between 1996 and June 2014, and the reference lists of all relevant articles found. Studies reporting on predictors/correlates of adherence of adults prescribed ART for chronic HIV infection were included without restriction to adherence assessment method, study design or geographical location. Two researchers independently extracted the data from the same papers. Random effects models with inverse variance weights were used to aggregate findings into pooled effects estimates with 95% confidence intervals. The standardized mean difference (SMD) was used as the common effect size. The impact of study design features (adherence assessment method, study design, and the United Nations Human Development Index (HDI) of the country in which the study was set) was investigated using categorical mixed effects meta-regression.

Results

In total, 207 studies were included. The following predictors/correlates were most strongly associated with adherence: adherence self-efficacy (SMD = 0.603, P = 0.001), current substance use (SMD = -0.395, P = 0.001), concerns about ART (SMD = -0.388, P = 0.001), beliefs about the necessity/utility of ART (SMD = 0.357, P = 0.001), trust/satisfaction with the HIV care provider (SMD = 0.377, P = 0.001), depressive symptoms (SMD = -0.305, P = 0.001), stigma about HIV (SMD = -0.282, P = 0.001), and social support (SMD = 0.237, P = 0.001). Smaller but significant associations were observed for the following being prescribed a protease inhibitor-containing regimen (SMD = -0.196, P = 0.001), daily dosing frequency (SMD = -0.193, P = 0.001), financial constraints (SMD -0.187, P = 0.001) and pill burden (SMD = -0.124, P = 0.001). Higher trust/satisfaction with the HIV care provider, a lower daily dosing frequency, and fewer depressive symptoms were more strongly related with higher adherence in low and medium HDI countries than in high HDI countries.

Conclusions

These findings suggest that adherence-enhancing interventions should particularly target psychological factors such as self-efficacy and concerns/beliefs about the efficacy and safety of ART. Moreover, these findings suggest that simplification of regimens might have smaller but significant effects.

Psychosocial burdens negatively impact HIV antiretroviral adherence in gay, bisexual, and other men who have sex with men aged 50 and older

We sought to characterize HIV antiretroviral therapy (ART) adherence and psychosocial correlates of adherence in a sample of gay, bisexual, and other non-gay or -bisexual identified men who have sex with men aged 50 and over. As part of a cross-sectional study we recruited a community-based sample of 199 men and assessed adherence to current ART medications along four domains: (1) missing doses in the past 4 days, (2) taking doses on the specified schedule in the past 4 days, (3) following instructions about how to take the medications (e.g., to take medications with food), and (4) missing doses in the last weekend. A total adherence score was also computed. Bivariable analyses indicated negative associations between depression, sexual compulsivity, and HIV-related stigma with each of the individual adherence variables and the composite adherence score, while an older age was found to be protective. In multivariable analyses, controlling for age and educational attainment, a higher likelihood of missing doses and failing to follow instructions were related to higher levels of HIV-related stigma, while dosing off-schedule and missing doses on weekends was associated with higher levels of sexual compulsivity. These results indicate that psychosocial burdens undermine the adherence behaviors of older HIV-positive sexual minority men. Programming and services to address this compromising health behavior must embrace a holistic approach to health as informed by syndemics theory, while attending to the developmental and age-specific needs of older men.

Alcohol abuse and HIV infection: role of DRD2

According to a survey from the HIV Cost and Services Utilization Study (HCSUS), approximately 53% of HIV-infected patients reported drinking alcohol and 8% were classified as heavy drinkers. The role of alcohol as a risk factor for HIV infection has been widely studied and recent research has found a significant association between heavy alcohol consumption and lower levels of CD4 T cells among HIV-infected alcoholics. Although there is evidence on the role of alcohol as a risk factor for HIV transmission and disease progression, there is a need for population studies to determine the genetic mechanisms that affect alcohol's role in HIV disease progression. One of the mechanisms of interest is the dopaminergic system. To date, the effects of dopamine on HIV neuroimmune pathogenesis are not well understood; however, dopaminergic neural degeneration due to HIV is known to occur by viral invasion into the brain via immune cells, and modulation of dopamine in the CNS may be a common mechanism by which different types of substances of abuse impact HIV disease progression. Although previous studies have shown an association of D(2) dopamine receptor (DRD2) polymorphisms with severity of alcohol dependence, the expression of this allele risk on HIV patients with alcohol dependence has not been systematically explored. In the current study, DRD2 Taq1A and C957T SNP genotyping analyses were performed in 165 HIV-infected alcohol abusers and the results were examined with immune status and CD4 counts.
