ART coverage and viral suppression among female sex workers living with HIV in eThekwini, South Africa: Baseline findings from the Siyaphambili study

In South Africa >60% of female sex workers (FSW) are living with HIV, the majority of whom are not virally suppressed. Identifying multi-level determinants of viral suppression is central to developing implementation strategies to promote retention in HIV care and viral suppression among FSW with unmet treatment needs. Adult cisgender FSW living with HIV for ≥6 months, conducting sex work as their primary source of income, and residing in Durban (South Africa) were enrolled into the Siyaphambili Study, a sequential multiple assignment randomized trial. Baseline viral load and CD4 were assessed, and an interviewer-administered survey was conducted, capturing socio-demographic, reproductive and sexual history and behaviors, vulnerabilities, substance use, mental health, and stigma. We assessed baseline determinants of viral suppression (<50 copies/mL) using bivariate and multivariable robust poisson regression, considering associations across the individual, network, environmental and macrostructural levels. From June 2018 -March 2020, 1,644 women were screened, with 1,391 eligible FSW living with HIV enrolled. The analyses were conducted among the 1,373 participants with baseline data. Overall, 65% (889/1,373) of participants were reported to be on antiretroviral therapy and 38% (520/1,373) were virally suppressed. In the multivariable model, FSW who experienced a lack of housing in the prior six months were less likely to be virally suppressed (aPR: 0.72, 95%CI 0.56-0.91), while older FSW (aPR: 1.46 95%CI: 1.16-1.83 for 30-39 years old vs. 18-29 years old; aPR: 2.15 95%CI: 1.64-2.80 for 40+ years vs. 18-29 years old) and FSW reporting hormonal or long-acting contraception use were more likely to be virally suppressed (aPR: 1.19 95% CI: 1.00-1.43). We found vulnerability to be high among FSW living with HIV in South Africa and identified individual and structural determinants associated with viral suppression. Taken together these results suggest optimizing HIV treatment outcomes necessitates supporting younger sex workers and addressing housing instability. Trial registration: NCT03500172.

Alcohol Use and Antiretroviral Therapy Non-Adherence Among Adults Living with HIV/AIDS in Sub-Saharan Africa: A Systematic Review and Meta-Analysis

Antiretroviral therapy (ART) is efficacious in improving clinical outcomes among people living with HIV (PLWH) and reducing HIV transmission when taken regularly. Research examining modifiable factors associated with ART non-adherence is critical for informing novel intervention development in settings with high HIV prevalence. Alcohol use has been linked with ART non-adherence in studies in sub-Saharan Africa; however, no review has pooled estimates across studies. We reviewed studies of alcohol use and ART non-adherence conducted in sub-Saharan Africa. We searched PubMed, CINAHL, EMBASE, and PsycINFO through August 2019 with terms related to ART non-adherence, alcohol use, and sub-Saharan Africa. One author reviewed titles/abstracts (n = 754) and two authors reviewed full texts (n = 308) for inclusion. Discrepancies were resolved by group consensus. Studies were retained if they quantitatively measured associations between alcohol use and ART non-adherence or viral non-suppression. We defined ART non-adherence using the definitions from each parent study (e.g., patients with > 5% missed ART doses during the previous four, seven or 30 days were considered non-adherent). A random effects meta-analysis was conducted to pool associations and we conducted additional analyses to assess between-study heterogeneity and publication bias and sensitivity analyses to determine robustness of our results when considering only certain study designs, alcohol use or ART scales, or studies that used viral non-suppression as their primary outcome. Of 56 articles meeting our inclusion criteria, 32 articles were included in the meta-analysis. All studies measured alcohol use via self-report. ART non-adherence was assessed using self-report, pill counts, or pharmacy records and definition of non-adherence varied depending on the measure used. Individuals who used alcohol had twice the odds of ART non-adherence compared with those who did not use alcohol (34% non-adherence among alcohol users vs. 18% among non-users; pooled odds ratio: 2.25; 95% confidence interval: 1.87-2.69; p < 0.001). We found evidence of a high degree of heterogeneity between studies (Cochrane Q statistic: 382.84, p< 0.001; I² proportion: 91.9%) and evidence of publication bias. However, the magnitude of our pooled odds ratio was consistent across a number of sensitivity analyses to account for heterogeneity and publication bias. In a secondary analysis with studies using viral non-suppression as their primary outcome, we also estimated a statistically significant pooled effect of alcohol use on viral non-suppression (pooled odds ratio: 2.47; 95% confidence interval: 1.58-3.87). Evidence suggests alcohol use is associated with ART non-adherence in Sub-Saharan Africa, potentially hindering achievement of the UNAIDS 90-90-90 HIV treatment targets.

Are health workers reduced to being drug dispensers of antiretroviral treatment? A randomized cross-sectional assessment of the quality of health care for HIV patients in northern Uganda

High quality of care (QoC) for antiretroviral treatment (ART) is essential to prevent treatment failure. Uganda, as many sub-Saharan African countries, increased access to ART by decentralizing provision to districts. However, little is known whether this rapid scale-up maintained high-quality clinical services. We assess the quality of ART in the Acholi and Lango sub-regions of northern Uganda to identify whether the technical quality of critical ART sub-system needs improvement. We conducted a randomized cross-sectional survey among health facilities (HF) in Acholi (n = 11) and Lango (n = 10). Applying lot quality assurance sampling principles with a rapid health facility assessment tool, we assessed ART services vis-à-vis national treatment guidelines using 37 indicators. We interviewed health workers (n = 21) using structured questionnaires, directly observed clinical consultations (n = 126) and assessed HF infrastructure, human resources, medical supplies and patient records in each health facility (n = 21). The district QoC performance standard was 80% of HF had to comply with each guideline. Neither sub-region complied with treatment guidelines. No HF displayed adequate: patient monitoring, physical examination, training, supervision and regular monitoring of patients' immunology. The full range of first and second line antiretroviral (ARV) medication was not available in Acholi while Lango had sufficient stocks. Clinicians dispensed available ARVs without benefit of physical examination or immunological monitoring. Patients reported compliance with drug use (>80%). Patients' knowledge of preventing HIV/AIDS transmission concentrated on condom use; otherwise it was poor. The poor ART QoC in northern Uganda raises major questions about ART quality although ARVs were dispensed. Poor clinical care renders patients' reports of treatment compliance as insufficient evidence that it takes place. Further studies need to test patients' immunological status and QoC in more regions of Uganda and elsewhere in sub-Saharan Africa to identify topical and geographical areas which are priorities for improving HIV care.

Patient-level outcomes and virologic suppression rates in HIV-infected patients receiving antiretroviral therapy in Rwanda

The Rwanda national HIV program has been successful at scaling up antiretroviral therapy (ART) to achieve universal access. The AIDSRelief Model of Care focuses on four key principles: (1) earlier initiation of ART; (2) use of durable, highly-potent, and sequence-friendly first-line ART regimens; (3) early detection of treatment failure; and (4) provision of community-based care and support to ensure optimal adherence and follow up/engagement in care. We conducted a retrospective cohort study of randomly-selected HIV-infected patients at AIDSRelief-supported sites using a stratified, random sample of 583 adults (>15 years) who initiated ART from 30 June 2008 to 1 February 2010. At ART initiation, the median patient age was 38 years, and 67% were female. The baseline median CD4+ cell count was 309 cells/mm³. Overall virologic suppression was 91%. Married/ever married status (adjusted prevalence odds ratio [aPOR] 3.75, 95% confidence interval [CI] 1.30-10.78) and self-reported adherence ≥95% in the past month (aPOR 2.76, 95% CI 1.00-7.62) were significantly associated with viral suppression in the multivariable model. Excellent virologic outcomes were achieved in Rwandan AIDSRelief sites utilizing the AIDSRelief Model of Care during the scale-up of ART in the country.

Depression and ART Initiation Among HIV Serodiscordant Couples in Kenya and Uganda

Depression is a known barrier for antiretroviral therapy (ART) adherence, but less is understood about its effects on ART initiation. We followed 1013 HIV-infected individuals participating in the Partners Demonstration Project, an open-label study of integrated pre-exposure prophylaxis (PrEP) and ART delivery for HIV serodiscordant couples in Kenya and Uganda. Associations between depression, measured annually with the Hopkins Symptoms Checklist-Depression (HSCL-D), and ART initiation were assessed with Cox proportional hazards regression. At enrollment, 162 participants (16.0%) reported symptoms consistent with probable depression, defined by a HSCL-D mean score >1.75, and this proportion decreased during study follow-up (6.7 and 3.6% at 12- and 24-months, respectively; p value < 0.001). Greater depressive symptom severity was associated with a greater likelihood of ART initiation overall (adjusted hazard ratio [aHR] 1.32, 95% CI 1.01-1.73) and among participants with CD4 count ≤ 350 cells/µl (aHR 1.30, 95% CI 1.01-1.67). Depression decreased 6 months after ART initiation (adjusted odds ratio [aOR] 0.34, 95% CI 0.23-0.51). Among East African HIV-infected persons in HIV serodiscordant couples, depression was not a barrier to ART initiation. ART initiation was associated with improved depressive symptoms in this setting.

Determinants of adherence to antiretroviral therapy among HIV-positive adults in sub-Saharan Africa: a systematic review

OBJECTIVE

The rapid scale up of antiretroviral treatment (ART) in sub-Saharan Africa (SSA) has resulted in an increased focus on patient adherence. Non-adherence can lead to drug-resistant HIV caused by failure to achieve maximal viral suppression. Optimal treatment requires the identification of patients at high risk of suboptimal adherence and targeted interventions. The aim of this review was to identify and summarise determinants of adherence to ART among HIV-positive adults.

DESIGN

Systematic review of adherence to ART in SSA from January 2002 to October 2014.

METHODS

A systematic search was performed in 6 databases (PubMed, Cochrane Library, EMBASE, Web of Science, Popline, Global Health Library) for qualitative and quantitative articles. Risk of bias was assessed. A meta-analysis was conducted for pooled estimates of effect size on adherence determinants.

RESULTS

Of the 4052 articles screened, 146 were included for final analysis, reporting on determinants of 161 922 HIV patients with an average adherence score of 72.9%. Main determinants of non-adherence were use of alcohol, male gender, use of traditional/herbal medicine, dissatisfaction with healthcare facility and healthcare workers, depression, discrimination and stigmatisation, and poor social support. Promoters of adherence included counselling and education interventions, memory aids, and active disclosure among people living with HIV. Determinants of health status had conflicting influence on adherence.

CONCLUSIONS

The sociodemographic, psychosocial, health status, treatment-related and intervention-related determinants are interlinked and contribute to optimal adherence. Clinics providing ART in SSA should therefore design targeted interventions addressing these determinants to optimise health outcomes.

Depression at Treatment Initiation Predicts HIV Antiretroviral Adherence in Uganda

We examined the relationship between depression (symptom type, diagnostic severity, and change over time) and adherence to HIV antiretroviral therapy (ART) with data from 3 longitudinal studies (N = 1021) of patients starting ART in Uganda. The Patient Health Questionnaire was used to assess depressive symptoms (total score; somatic and cognitive subscales) and categorize severity level. At baseline, 9% had major depression and 30% had minor depression; 82% were adherent (reported no missed ART doses in the past 7 days) at month 6 and 85% at month 12. Controlling for demographic and medical covariates, multivariate random-effects logistic regression models revealed that change in depression was not related to adherence; however, baseline total depression symptoms and cognitive symptoms in particular as well as major and minor depression were significant predictors of adherence. These findings highlight the need for early identification and aggressive treatment of depression to optimize ART adherence.

High-risk alcohol use and associated socio-demographic, health and psychosocial factors in patients with HIV infection in three primary health care clinics in South Africa

Alcohol use may have a negative impact on the course of HIV disease and the effectiveness of its treatment. We studied patients with HIV who use alcohol and associated socio-demographic, health and psychosocial factors. Outcomes from this study may help in selecting patients from clinical practice with high-risk alcohol use and who are likely to benefit most from alcohol reduction interventions. In a cross sectional study in three primary health care clinics in Pretoria, South Africa, from January 2012 to June 2012, patients with HIV infection were interviewed and patients' medical files were reviewed to obtain data on levels of alcohol use (Alcohol Use Disorder Identification Test), patients' socio-demographic characteristics, HIV-related information, health related quality of life (WHOQoL-HIVBref), internalized AIDS stigma, symptoms of depression and adherence to antiretroviral therapy. Analyses consisted of descriptive statistics, bi- and multivariate logistic regression models. A total of 2230 patients (1483 [66.5%] female) were included. The median age was 37 years (interquartile range 31-43), 99.5% were black Africans, 1975 (88.6%) had started ART and the median time on ART was 22 months (interquartile range 9-40). No alcohol was used by 64% of patients, 8.9% were low risk drinkers, 25.1% of patients were hazardous or harmful drinkers and 2.0% had possible alcohol dependence. In multivariate analysis high-risk drinking was positively associated with male gender, never being married, tobacco use, a higher score for the 'level of independence'-domain measured with the WHOQoL-HIVBref questionnaire, and with more depressive symptoms compared to low-risk drinking. This study shows a high prevalence of hazardous or harmful drinking in patients with HIV infection (especially men) attending primary health care clinics in South Africa. Routine screening for alcohol use should be introduced in these clinics and harm reduction interventions should be evaluated, taking into account associated factors.

Relationship between depressive symptoms, alcohol use, and antiretroviral therapy adherence among HIV-infected, clinic-attending patients in South Africa

Despite the prevalence of depression and alcohol use among HIV-infected individuals, few studies have examined their association together in relation to nonadherence to antiretroviral therapy in sub-Saharan Africa. This study examined depressive symptoms, alcohol use, and other psychosocial factors (stigma, demographic characteristics) in relation to nonadherence to antiretroviral therapy among clinic-attending, HIV-infected individuals in South Africa ( n = 101). Nonadherence was assessed using event-level measurement (missed doses over the past weekend). Multivariable logistic regression analyses revealed that only alcohol use, over and above depressive symptoms and education level, was associated with antiretroviral therapy nonadherence(AOR = 1.15; 95%CI = 1.02-1.29; p < .05). Findings point to the independent association of alcohol use and nonadherence to antiretroviral therapy above and beyond depressive symptoms.

Religious Beliefs and Depression: Psychosocial Factors Affecting HIV Treatment Outcomes in South Africa

Analyzing factors associated with virological failure (VF) may improve antiretroviral therapy (ART) outcomes for individuals living with HIV. The Risk Factors for Virological Failure (RFVF) study compared 158 cases with VF (viral load, VL, >1,000 copies/mL) and 300 controls with virological suppression (VL ≤1,000 copies/mL) after ≥5 months on their first ART regimen at McCord Hospital in Durban, South Africa between October 2010 and June 2012. RFVF participants completed a battery of various psychosocial measures. Using multivariate logistic regression stratified for gender, the association of various psychosocial factors with VF was assessed. It was found that not all factors were equally significant for both genders. The factors that were significantly associated with VF for both genders were younger age, shorter treatment duration and reporting depressive symptoms. The factors associated with VF that differed by gender were religious inactivity, having HIV+ family members, and status disclosure to friends.

A psychosocial perspective of medication side effects, experiences, coping approaches and implications for adherence in hypertension management

INTRODUCTION

This study examined whether psychosocial variables influenced patients' perception and experience of side effects of their medicines, how they coped with these experiences and the impact on medication adherence behaviour.

METHODS

A hospital-based mixed methods study using quantitative and qualitative approaches was conducted with hypertensive patients. Participants were asked about side effects, medication adherence, common psychological symptoms and coping mechanisms with the aid of standard questionnaires and an interview guide.

RESULTS

The experiences of side effects-such as palpitations, frequent urination, recurrent bouts of hunger, erectile dysfunction, dizziness, cough, physical exhaustion-were categorized as no/low (39.75 %), moderate (53.0 %) and high (7.25 %). Significant relationships between depression (x (2) = 24.21, p < 0.0001), anxiety (x (2) = 42.33, p < 0.0001), stress (x (2) = 39.73, p < 0.0001) and side effects were observed. A logistic regression model using the adjusted results for this association is reported-depression [OR = 1.9 (1.03-3.57), p = 0.04], anxiety [OR = 1.5 (1.22-1.77), p ≤ 0.001] and stress [OR = 1.3 (1.02-1.71), p = 0.04]. Side effects significantly increased the probability of individuals to be non-adherent [OR = 4.84 (95 % CI 1.07-1.85), p = 0.04] with social factors, media influences and attitudes of primary care givers further explaining this relationship. Personal adoption of medication modifying strategies, espousing the use of complementary and alternative treatments and interventions made by clinicians were the main forms of coping with side effects.

DISCUSSION

Results from this study show that, in addition to a biomedical approach, the experience of side effects has biological, social and psychological interrelations. The results offer more support for the need for a multi-disciplinary approach to healthcare where all forms of expertise are incorporated into health provision and patient care.

Implementation of HIV Palliative Care: Interprofessional Education to Improve Patient Outcomes in Resource-Constrained Settings, 2004-2012

Palliative care (PC), introduced early in the management of chronic illness, improves patient outcomes. Early integration of a palliative approach for persons with HIV has been documented to be effective in identifying and managing patient-level concerns over the past decade in African settings. The experience of implementing PC in multiple African and other resource-constrained settings (RCSs) emphasizes the need for essential palliative competencies that can be integrated with chronic disease management for patients and their families facing life-limiting illness. This article is an historical description of how basic palliative competencies were observed to be acceptable for health workers providing outpatient HIV care and treatment during eight years of U.S. implementation of "care and support," a term coined to represent PC for persons living with HIV in RCS. The need for team building and interprofessional education is highlighted. The model is currently being tested in one U.S. city and may represent a mechanism for expanding the palliative approach into management of chronic disease. Such competencies may play a role in the development of the patient-centered medical home, a critical component of U.S. health care reform.

Rethinking HIV prevention to prepare for oral PrEP implementation for young African women

INTRODUCTION

HIV incidence remains high among young women in sub-Saharan Africa in spite of scale-up of HIV testing, behavioural interventions, antiretroviral treatment and medical male circumcision. There is a critical need to critique past approaches and learn about the most effective implementation of evidence-based HIV prevention strategies, particularly emerging interventions such as pre-exposure prophylaxis (PrEP).

DISCUSSION

Women in sub-Saharan Africa are at increased risk of HIV during adolescence and into their 20s, in part due to contextual factors including gender norms and relationship dynamics, and limited access to reproductive and sexual health services. We reviewed behavioural, behavioural economic and biomedical approaches to HIV prevention for young African women, with a particular focus on the barriers, opportunities and implications for implementing PrEP in this group. Behavioural interventions have had limited impact in part due to not effectively addressing the context, broader sexual norms and expectations, and structural factors that increase risk and vulnerability. Of biomedical HIV prevention strategies that have been tested, daily oral PrEP has the greatest evidence for protection, although adherence was low in two placebo-controlled trials in young African women. Given high efficacy and effectiveness in other populations, demonstration projects of open-label PrEP in young African women are needed to determine the most effective delivery models and whether women at substantial risk are motivated and able to use oral PrEP with sufficient adherence to achieve HIV prevention benefits.

CONCLUSIONS

Social marketing, adherence support and behavioural economic interventions should be evaluated as part of PrEP demonstration projects among young African women in terms of their effectiveness in increasing demand and optimizing uptake and effective use of PrEP. Lessons learned through evaluations of implementation strategies for delivering oral PrEP, a first-generation biomedical HIV prevention product, will inform development of new and less user-dependent PrEP formulations and delivery of an expanding choice of prevention options in HIV prevention programmes for young African women.

Qualitative study of changes in alcohol use among HIV-infected adults entering care and treatment for HIV/AIDS in rural southwest Uganda

Alcohol has a substantial negative impact on the HIV epidemic in sub-Saharan Africa, particularly in Uganda, where heavy alcohol consumption is common. Using a content analytic approach, this qualitative study characterizes changes in alcohol use among 59 HIV-infected Ugandan adults (>18 years old), who reported any alcohol use in the previous year as they entered HIV care. Most participants reported attempting to cease or reduce alcohol intake over the study period. Reasons for decreased use included advice from clinicians, interference with social obligations, threats to financial security, and negative impact on social standing. Participants reported difficulty abstaining from alcohol, with incentives to continue drinking including desire for social inclusion, stress relief, and enjoyment of alcohol. These contrasting incentives created a moral quandary for some participants, who felt 'pulled' between 'good' and 'bad' influences. Results suggest brief interventions addressing self-identified obstacles to change may facilitate long-term reductions in drinking in this population.

'I was thinking too much': experiences of HIV-positive adults with common mental disorders and poor adherence to antiretroviral therapy in Zimbabwe

OBJECTIVE

To document the lived experiences of people with both poor mental health and suboptimal adherence to antiretroviral therapy in high HIV prevalence settings.

METHODS

In-depth qualitative interviews were conducted with 47 (female = 31) HIV-positive adults who scored above the cut-point on a locally validated scale for common mental disorders (CMDs). Purposive sampling was used to recruit participants with evidence of poor adherence. Six additional key informant interviews (female = 6) were conducted with healthcare workers. Data were collected and analysed inductively by an interdisciplinary coding team.

RESULTS

The major challenges faced by participants were stressors (poverty, stigma, marital problems) and symptoms of CMDs ('thinking too much', changes to appetite and sleep, 'burdened heart' and low energy levels). Thinking too much, which appears closely related to rumination, was the symptom with the greatest negative impact on adherence to antiretroviral therapy among HIV-positive adults with CMDs. In turn, thinking too much was commonly triggered by the stressors faced by people living with HIV/AIDS, especially poverty. Finally, participants desired private counselling, access to income-generating activities and family engagement in mental health care.

CONCLUSIONS

Better understanding of the local expression of mental disorders and of underlying stressors can inform the development of culturally sensitive interventions to reduce CMDs and poor adherence to antiretroviral therapy.

The effect of depressive symptoms and CD4 count on adherence to highly active antiretroviral therapy in sub-Saharan Africa

BACKGROUND

Studies have identified several programmatic and nonprogrammatic indicators that affect adherence to highly active antiretroviral therapy (HAART). Depression has been shown to impact adherence to HAART. This cross-sectional analysis of data collected from Nigeria, Uganda, Zambia, and Tanzania in 2008 examined the relationship between levels of depressive symptoms, clinical progression, and adherence to HAART.

METHODS

A multinational, multicenter, observational, retrospective cross-sectional evaluation of a population of focus comprised randomly selected patients on HAART. The dependent variable was adherence to HAART. The primary variable of interest to be assessed was patients' level of depressive symptom score. A multivariable logistic regression model was used to examine the relationship between explanatory variables and adherence to HAART.

RESULTS

A total of 2344 patients were recruited for adherence survey. About 70% of the study sample reported having some level of depression. Logistic regression results show that patients who reported, respectively, low, moderate, and high levels of depressive symptoms are 35% (P < .001), 56% (P < .001), and 64% (P < .001) less likely to adhere to HAART than those who reported having no depressive symptoms. At multivariate analysis, adherence to HAART was independently associated with the levels of depressive symptoms, older age, CD4 count >200 cells/mm3, Truvada (tenofovir [TDF]/emtricitabine [FTC])-based regimens, good knowledge about HAART, and longer period on therapy.

CONCLUSIONS

These results indicate that mental health and clinical parameters are significant factors in determining patients' adherence to their HAART, which need to be more aggressively addressed as a critical component of care and treatment support.

Depression and adherence to antiretroviral therapy in low-, middle- and high-income countries: a systematic review and meta-analysis

We investigated the associations between depressive symptoms and adherence to antiretroviral therapy (ART) among people living with HIV (PLHIV). We searched the PubMed, EMBASE and Cochrane CENTRAL databases for studies that reported an association between depression and adherence to ART as a primary or secondary outcome. We used a random-effect model to pool the risk estimates from the individual studies. The odds ratio (OR) with their 95 % CIs were used as summary estimates. Of 2861 citations, 111 studies that recruited 42,366 PLHIV met our inclusion criteria. When reported, the rate of PLHIV with depressive symptoms ranged from 12.8 to 78 % and the proportion of PLHIV who achieved good adherence (≥ 80 %) ranged from 20 to 98 %. There were no significant differences in rate of depressive symptoms in PLHIV by country income group; however, the proportion of PLHIV who achieved good adherence was significantly higher in lower-income countries (as defined in the 2012 World Bank Country Income Groups) (pooled rate=86 %) compared to higher-income countries (pooled rate=67.5 %; p< .05). We found that the likelihood of achieving good ART adherence was 42 % lower among those with depressive symptoms compared to those without (pooled OR=0.58, 95 % CI 0.55 to 0.62). The relationship between depressive symptoms and adherence to ART was consistent across the country's income group, study design and adherence rates. We found that the magnitude of the association significantly decreases with more recent publications and increasing study sample size. The higher the prevalence of depressive symptoms of PLHIV recruited in the studies, the lower the likelihood of achieving good adherence to ART. In conclusion, the likelihood of achieving good adherence was lower among those with depressive symptoms compared to those without.

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.

Moreover, these findings suggest that simplification of regimens might have smaller but significant effects.

Evaluation of treatment outcomes for patients on first-line regimens in US President's Emergency Plan for AIDS Relief (PEPFAR) clinics in Uganda: predictors of virological and immunological response from RV288 analyses

OBJECTIVES

Viral load (VL) monitoring is recommended, but seldom performed, in resource-constrained countries. RV288 is a US President's Emergency Plan for AIDS Relief (PEPFAR) basic programme evaluation to determine the proportion of patients on treatment who are virologically suppressed and to identify predictors of virological suppression and recovery of CD4 cell count. Analyses from Uganda are presented here.

METHODS

In this cross-sectional, observational study, patients on first-line antiretroviral therapy (ART) (efavirenz or nevirapine+zidovudine/lamivudine) from Kayunga District Hospital and Kagulamira Health Center were randomly selected for a study visit that included determination of viral load (HIV-1 RNA), CD4 cell count and clinical chemistry tests. Subjects were recruited by time on treatment: 6-12, 13-24 or >24 months. Logistic regression modelling identified predictors of virological suppression. Linear regression modelling identified predictors of CD4 cell count recovery on ART.

RESULTS

We found that 85.2% of 325 subjects were virologically suppressed (viral load<47 HIV-1 RNA copies/ml). There was no difference in the proportion of virologically suppressed subjects by time on treatment, yet CD4 counts were higher in each successive stratum. Women had higher median CD4 counts than men overall (406 vs. 294 cells/μL, respectively; P<0.0001) and in each time-on-treatment stratum. In a multivariate logistic regression model, predictors of virological suppression included efavirenz use [odds ratio (OR) 0.47; 95% confidence interval (CI) 0.22-1.02; P=0.057], lower cost of clinic visits (OR 0.815; 95% CI 0.66-1.00; P=0.05), improvement in CD4 percentage (OR 1.06; 95% CI 1.014-1.107; P=0.009), and care at Kayunga vs. Kangulamira (OR 0.47; 95% CI 0.23-0.92; P=0.035). In a multivariate linear regression model of covariates associated with CD4 count recovery, time on highly active antiretroviral therapy (ART) (P<0.0001), patient satisfaction with care (P=0.038), improvements in total lymphocyte count (P<0.0001) and haemoglobin concentration (P=0.05) were positively associated, whereas age at start of ART (P=0.0045) was negatively associated with this outcome.

CONCLUSIONS

High virological suppression rates are achievable on first-line ART in Uganda. The odds of virological suppression were positively associated with efavirenz use and improvements in CD4 cell percentage and total lymphocyte count and negatively associated with the cost of travel to the clinic. CD4 cell reconstitution was positively associated with CD4 count at study visit, time on ART, satisfaction with care at clinic, haemoglobin concentration and total lymphocyte count and negatively associated with age.

Mental health in hypertension: assessing symptoms of anxiety, depression and stress on anti-hypertensive medication adherence

Background

Patients with chronic conditions like hypertension may experience many negative emotions which increase their risk for the development of mental health disorders particularly anxiety and depression. For Ghanaian patients with hypertension, the interaction between hypertension and symptoms of anxiety, depression and stress remains largely unexplored. To fill this knowledge gap, the study sought to ascertain the prevalence and role of these negative emotions on anti-hypertensive medication adherence while taking into account patients’ belief systems.

Methods

The hospital-based cross-sectional study involving 400 hypertensive patients was conducted in two tertiary hospitals in Ghana. Data were gathered on patient’s socio-demographic characteristics, anxiety, depression and stress symptoms, spiritual beliefs, and medication adherence.

Results

Hypertensive patients experienced symptoms of anxiety (56%), stress (20%) and depression (4%). As a coping mechanism, a significant relation was observed between spiritual beliefs and anxiety (x² = 13.352, p = 0.010), depression (x² = 6.205, p = 0.045) and stress (x² = 14.833, p = 0.001). Stress among patients increased their likelihood of medication non-adherence [odds ratio (OR) = 2.42 (95% CI 1.06 – 5.5), p = 0.035].

Conclusion

The study has demonstrated the need for clinicians to pay attention to negative emotions and their role in medication non-adherence. The recommendation is that attention should be directed toward the use of spirituality as a possible mechanism by which negative emotions could be managed among hypertensive patients.

Pain Management for Persons Living With HIV Disease

Context:

Pain management (PM) has not been routinely incorporated into HIV/AIDS care and treatment in resource-constrained settings.

Objectives:

We describe training for multidisciplinary teams tasked with integrating care management into HIV clinics to address pain for persons living with HIV in Nigeria.

Methods:

Education on PM was provided to mixed-disciplinary teams including didactic and iterative sessions following home and hospital visits. Participants identified challenges and performed group problem solving.

Results:

HIV trainers identified barriers to introducing PM reflecting views of the patient, providers, culture, and the health environment. Implementation strategies included (1) building upon existing relationships; (2) preliminary advocacy; (3) attention to staff needs; and (4) structured data review.

Conclusion:

Implementing PM in Nigerian HIV clinics requires recognition of cultural beliefs.

Reduced adherence to antiretroviral therapy among HIV-infected Tanzanians seeking cure from the Loliondo healer

: The predictors for seeking alternative therapies for HIV-infection in sub-Saharan Africa are unknown. Among a prospective cohort of 442 HIV-infected patients in Moshi, Tanzania, 249 (56%) sought cure from a newly popularized religious healer in Loliondo (450 km away), and their adherence to antiretrovirals (ARVs) dropped precipitously (odds ratio = 0.20, 95% confidence interval: 0.09 to 0.44, P < 0.001) after the visit. Compared with those not attending Loliondo, attendees were more likely to have been diagnosed with HIV more remotely (3.8 vs. 3.0 years before, P < 0.001), have taken ARVs longer (3.4 vs. 2.5 years, P < 0.001), have higher median CD4 lymphocyte counts (429 vs. 354 cells/mm, P < 0.001), be wealthier (wealth index: 10.9 vs. 8.8, P = 0.034), and receive care at the private versus the public hospital (P = 0.012). In multivariable logistic regression, only years since the start of ARVs remained significant (odds ratio = 1.49, 95% confidence interval: 1.23 to 1.80). Treatment fatigue may play a role in the lure of alternative healers.

Alcohol use, antiretroviral therapy adherence, and preferences regarding an alcohol-focused adherence intervention in patients with human immunodeficiency virus

BACKGROUND

The primary objectives of this study were to determine the association between alcohol and antiretroviral therapy (ART) adherence and the perceived appropriateness and acceptability of elements of an adherence counseling program with a focus on alcohol-related ART nonadherence among a sample of ART recipients in human immunodeficiency virus (HIV) clinics in Tshwane, South Africa.

METHODS

We conducted a cross-sectional study with purposive sampling. The sample comprised 304 male and female ART recipients at two President's Emergency Plan For AIDS Relief-supported HIV clinics. Using an interview schedule, we assessed patients' alcohol use (Alcohol Use Disorders Identification Test), other drug use, level of adherence to ART, and reasons for missing ART doses (AIDS Clinical Trials Group adherence instrument). Additionally, patients' views were solicited on: the likely effectiveness of potential facilitators; the preferred quantity, duration, format, and setting of the sessions; the usefulness of having family members/friends attend sessions along with the patient; and potential skill sets to be imparted.

RESULTS

About half of the male drinkers' and three quarters of the female drinkers' Alcohol Use Disorders Identification Test scores were suggestive of hazardous or harmful drinking. Average self-reported ART adherence was 89.7%. There was a significant association between level of alcohol use and degree of ART adherence. Overall, participants perceived two clinic-based sessions, each of one hour's duration, in a group format, and facilitated by a peer or adherence counselor, as most appropriate and acceptable. Participants also had a favorable attitude towards family and friends accompanying them to the sessions. They also favored an alcohol-focused adherence counseling program that employs motivational interviewing and cognitive behavioral therapy-type approaches.

CONCLUSION

The association between alcohol use and ART nonadherence points to a need for alcohol-focused ART adherence interventions. Patients' perceptions suggest their amenability to clinic-based brief motivational interviewing and cognitive behavioral therapy-type adherence interventions delivered by lay persons in group settings. Further research should investigate how best to implement such interventions in the existing health system.

Stigma in Ethiopia: association with depressive symptoms in people with HIV

Rates of depression among people living with HIV can be as high as 50%. In many settings, HIV-related stigma has been associated with depressive symptoms which may lead to poor engagement in care and ultimately, poorer health outcomes. Stigma is a major issue in Ethiopia but data examining the relationship between stigma and depression in Ethiopia are lacking. We performed a mixed-methods cross-sectional study to examine the relationship between stigma of HIV/AIDS and depressive symptoms in Gondar, Ethiopia. We interviewed patients who presented for routine HIV care at Gondar University Hospital during the study period, examining depressive symptoms and HIV/AIDS-related stigma using standardized measures. Multiple-regression was used to assess the relationship between depressive symptoms, stigma, and gender. Of 55 patients included in this analysis, 63.6% were female and most participants had limited formal education (69%, less than 12th grade education). The majority reported experiencing both stigma (78%) and depressive symptoms (60%) ranging in severity from mild to moderately severe. Higher levels of HIV-related stigma were significantly associated with higher levels of depressive symptoms (β = 0.464, p ≤ 0.001). Although gender was associated with stigma, it was not associated with depressive symptoms (β = -0.027, p > 0.05). Results suggest the importance of psychosocial issues in the lives of people with HIV in Ethiopia.

Lifetime depressive disorders and adherence to anti-retroviral therapy in HIV-infected Ugandan adults: a case-control study

BACKGROUND

There is limited information on the impact of lifetime depressive disorders on adherence to ART.

AIM

We examined the association between lifetime depressive disorders and adherence to anti-retroviral therapy (ART) among a rural clinic-based HIV positive population. We further explored whether this association was mediated by current depression and moderated by gender.

METHODS

Two hundred HIV positive individuals who had<95% adherence and two hundred HIV positive individuals who had ≥95% adherence were screened for depression using the self-reporting questionnaire (SRQ-20) and evaluated with the Mini neuropsychiatric interview (MINI). Multivariate logistic regression was used to assess the association between lifetime depressive disorders and adherence to ART. The logistic regression model of Baron and Kenny was used to evaluate the mediating effect of current depression. Hierarchical binomial logistic regression was used to evaluate the moderating effect of gender.

RESULTS

HIV positive individuals with lifetime depressive disorders had an increased risk of non-adherence to ART after controlling for education status, income, self-efficacy, perceived social support, cognitive impairment and current alcohol use disorders [AOR=1.68, 95%CI (1.02-2.79), p=0.04]. This association was stronger in females than males [AOR= 4.76, 95%CI (1.52-14.97), p=0.008].

LIMITATIONS

Findings cannot be generalized to ART naïve individuals or those using ART for less than six months.

CONCLUSION

Lifetime depressive disorders are associated with increased risk of non-adherence to ART in rural women with HIV infection in southern Uganda. Detection and treatment of depression can potentially improve adherence with HIV treatment in this setting.

Missed Doses and Missed Appointments: Adherence to ART among Adult Patients in Uganda

Background. Missed doses and appointments are predictors of incomplete adherence among patients on ART. The AIDSRelief model emphasizes treatment preparation and continuous treatment support for ART patients including community followup. Methods. In August 2008, a survey was conducted among patients on antiretroviral therapy (ART) (interquartile range for duration of ART = 29-46 months, median = 33 months, n = 763, age >16 years), in 15 health facilities in Uganda. Missed doses and appointments among adult patients on ART and the factors most associated with these were identified. Reasons for missed doses were also explored. Results. The survey revealed that 97% of the patients had not missed their doses in the last week while 93% had not missed their appointments in the last three months. For those who had missed their doses, the most common reasons were travel (48%) and forgetfulness (28%). There was a significant association between missing doses and missing appointments (P = 0.0004) and between alcohol use and missed doses (P < 0.005). Conclusions. The level of adherence to medication and clinic appointments for patients on ART in the study population was very high. It is important to strengthen adherence strategies at both facility and community levels to assist patients that are likely to miss their doses or appointments.

High levels of adherence and viral suppression in a nationally representative sample of HIV-infected adults on antiretroviral therapy for 6, 12 and 18 months in Rwanda

Background

Generalizable data are needed on the magnitude and determinants of adherence and virological suppression among patients on antiretroviral therapy (ART) in Africa.

Methods

We conducted a cross-sectional survey with chart abstraction, patient interviews and site assessments in a nationally representative sample of adults on ART for 6, 12 and 18 months at 20 sites in Rwanda. Adherence was assessed using 3- and 30-day patient recall. A systematically selected sub-sample had viral load (VL) measurements. Multivariable logistic regression examined predictors of non-perfect (<100%) 30-day adherence and detectable VL (>40 copies/ml).

Results

Overall, 1,417 adults were interviewed and 837 had VL measures. Ninety-four percent and 78% reported perfect adherence for the last 3 and 30 days, respectively. Eighty-three percent had undetectable VL. In adjusted models, characteristics independently associated with higher odds of non-perfect 30-day adherence were: being on ART for 18 months (vs. 6 months); younger age; reporting severe (vs. no or few) side effects in the prior 30 days; having no documentation of CD4 cell count at ART initiation (vs. having a CD4 cell count of <200 cells/µL); alcohol use; and attending sites which initiated ART services in 2003–2004 and 2005 (vs. 2006–2007); sites with ≥600 (vs. <600 patients) on ART; or sites with peer educators. Participation in an association for people living with HIV/AIDS; and receiving care at sites which regularly conduct home-visits were independently associated with lower odds of non-adherence. Higher odds of having a detectable VL were observed among patients at sites with peer educators. Being female; participating in an association for PLWHA; and using a reminder tool were independently associated with lower odds of having detectable VL.

Conclusions

High levels of adherence and viral suppression were observed in the Rwandan national ART program, and associated with potentially modifiable factors.

Depression, alcohol use and adherence to antiretroviral therapy in sub-Saharan Africa: a systematic review

This study evaluated estimates of depression symptoms, major depression, alcohol use or disorders and their association with ART adherence in sub-Saharan Africa. Studies published between January 1, 2006 and July 31, 2011 that documented rates of these mental health problems were identified through electronic databases. A pooled analysis of 23 studies reporting rates of depression symptoms and six studies reporting rates of major depression indicated a pooled estimate of 31.2% (95% CI 25.5-38.2%, Tau(2) = 0.23) and 18% (95% CI 12.3-25.8%, Tau(2) = 0.19) respectively. Few studies reported rates of alcohol use or disorders, and so we did not pool their estimates. Likelihood of achieving good adherence was 55% lower among those with depression symptoms compared to those without (pooled OR = 0.45 (95% CI 0.31-0.66, Tau(2) = 0.20, P value = 0.000). Interventions to improve mental health of HIV-positive individuals and to support adherence are desperately needed in sub-Saharan Africa.

The impact of DSM-IV mental disorders on adherence to combination antiretroviral therapy among adult persons living with HIV/AIDS: a systematic review

This is a systematic review of eighty-two published studies investigating the impact of DSM-IV mental disorders on combination antiretroviral therapy (cART) adherence and persistence among persons living with HIV/AIDS (PLWHA). Sixty-two articles examined depression, with 58 % (N = 32/62) finding lower cART adherence and persistence. Seventeen articles examined one or more anxiety disorders, with the majority finding no association with cART adherence or persistence. Eighty percent of the studies that evaluated the impact of psychotic (N = 3), bipolar (N = 5) and personality disorders (N = 2) on cART adherence and persistence also found no association. Seven out of the nine studies (78 %) evaluating the impact of antidepressant treatment (ADT) on cART adherence found improvement. Adherence and depression measurements varied significantly in studies; common research measurements would improve data harmonization. More research specifically addressing the impact of other mental disorders besides depression on cART adherence and RCTs evaluating ADT on cART adherence are also needed.

The efficacy of a brief intervention to reduce alcohol misuse in patients with HIV in South Africa: study protocol for a randomized controlled trial

Background

Alcohol abuse comes with risks for increased morbidity and mortality among patients with HIV. This study aims to determine the prevalence of alcohol use and other risk factors in a sample of primary care patients with HIV in South Africa and to assess a brief intervention to reduce the use of alcohol in this group.

Methods/Design

A single-blinded randomized controlled trial is designed to determine the efficacy of a brief intervention to reduce hazardous alcohol use in patients with HIV. The study will be carried out on out-patients with HIV in two primary healthcare HIV clinics near Pretoria, South Africa. Alcohol use will be assessed with the Alcohol Use Disorder Identification Test questionnaire. Other data that will be collected relate to health-related quality of life, depression, sexual behavior, internalized AIDS stigma, HIV-related information and adherence to antiretroviral therapy (self-reported 7-day recall of missed doses, Visual Analog Scale and pill count). The intervention consists of a brief counseling session to reduce alcohol risk; the control group receives a health education leaflet.

Discussion

The findings will be important in the public health setting. If the intervention proves to be efficient, it could potentially be incorporated into the HIV care policy of the Ministry of Health.

HIV in Africa: Challenges and Directions for the Next Decade

Africa carries a disproportionate burden of the global HIV endemic, accounting for two thirds of the global 33.3 million people living with HIV. While tremendous advances have been made in addressing the HIV epidemic in Africa, considerable challenges remain. Testing for HIV increased by 86% from 2007 to 2009 but more than 75% of people 15-49 years remain unaware of their HIV status. CD4 count at diagnosis tends to be low and linkage to care and treatment is suboptimal. The scale-up of antiretroviral therapy is ongoing but is hampered by the lack of diagnostic capability to monitor response to therapy and a substantial healthcare workforce shortage. Prevention strategies such as male circumcision, pre-exposure prophylaxis, and antiretroviral therapy for prevention have generated great excitement but cost and healthcare infrastructure deficiencies may limit their widespread applicability. Operational research to validate and inform treatment decisions, health care policies, and prevention strategies is sorely needed.

Factors associated with patterns of plural healthcare utilization among patients taking antiretroviral therapy in rural and urban South Africa: a cross-sectional study

Background

In low-resource settings, patients’ use of multiple healthcare sources may complicate chronic care and clinical outcomes as antiretroviral therapy (ART) continues to expand. However, little is known regarding patterns, drivers and consequences of using multiple healthcare sources. We therefore investigated factors associated with patterns of plural healthcare usage among patients taking ART in diverse South African settings.

Methods

A cross-sectional study of patients taking ART was conducted in two rural and two urban sub-districts, involving 13 accredited facilities and 1266 participants selected through systematic random sampling. Structured questionnaires were used in interviews, and participant’s clinic records were reviewed. Data collected included household assets, healthcare access dimensions (availability, affordability and acceptability), healthcare utilization and pluralism, and laboratory-based outcomes. Multiple logistic regression models were fitted to identify predictors of healthcare pluralism and associations with treatment outcomes. Prior ethical approval and informed consent were obtained.

Results

Nineteen percent of respondents reported use of additional healthcare providers over and above their regular ART visits in the prior month. A further 15% of respondents reported additional expenditure on self-care (e.g. special foods). Access to health insurance (Adjusted odds ratio [aOR] 6.15) and disability grants (aOR 1.35) increased plural healthcare use. However, plural healthcare users were more likely to borrow money to finance healthcare (aOR 2.68), and incur catastrophic levels of healthcare expenditure (27%) than non-plural users (7%). Quality of care factors, such as perceived disrespect by staff (aOR 2.07) and lack of privacy (aOR 1.50) increased plural healthcare utilization. Plural healthcare utilization was associated with rural residence (aOR 1.97). Healthcare pluralism was not associated with missed visits or biological outcomes.

Conclusion

Increased plural healthcare utilization, inequitably distributed between rural and urban areas, is largely a function of higher socioeconomic status, better ability to finance healthcare and factors related to poor quality of care in ART clinics. Plural healthcare utilization may be an indication of patients’ dissatisfaction with perceived quality of ART care provided. Healthcare expenditure of a catastrophic nature remained a persistent complication. Plural healthcare utilization did not appear to influence clinical outcomes. However, there were potential negative impacts on the livelihoods of patients and their households.

Depression in HIV-positive women in Gaborone, Botswana

This cross-sectional study measured prevalence of depression and suicide ideation in 62 randomly selected HIV-positive (HIV+) women in Botswana, a resource-limited country at the center of the HIV/AIDS epidemic. They were administered two screening measures of depression, an inventory of activities of daily living (ADL), and subjective questionnaire of cognitive functioning. Results show that the two screening measures are useful for detecting depression in women infected with HIV in resource-limited countries. Diagnosis of depression is of great importance, not only clinically, but also to ensure judicious allocation of scarce medical resources in the regions worst affected by the HIV epidemic.

Cross-cultural adaptation and validation of the self-reporting questionnaire among HIV+ individuals in a rural ART program in southern Uganda

BACKGROUND

HIV treatment programs are in need of brief, valid instruments to identify common mental disorders such as depression.

AIM

To translate and culturally adapt the Self-Reporting Questionnaire (SRQ-20) for use in Uganda and to investigate its psychometric properties in this setting.

METHODS

Following an initial translation of the SRQ-20 from English to Luganda, key informant interviews and focus-group discussions were used to produce a culturally adapted version of the instrument. The adapted SRQ-20 was administered to 200 HIV-positive individuals in a rural antiretroviral therapy program in southern Uganda. All study participants were also evaluated by a psychiatric clinical officer with the Mini International Neuropsychiatric Interview (MINI). Receiver-operating-characteristic analysis was used to examine the sensitivity and specificity of the SRQ-20 compared to the clinical diagnosis generated by the MINI.

RESULTS

The prevalence estimates of any depressive disorder and current depression were 24% (n = 48) and 12% (n = 24), respectively. The SRQ-20 scores discriminated well between subjects with and without current depression based on the MINI, with an area under the curve of 0.92, as well as between subjects with and without any current or past depressive disorder, with an area under the curve of 0.75. A score of 6 or more had 84% sensitivity and 93% specificity for current depression, and 75% sensitivity and 90% specificity for any depressive disorder.

CONCLUSION

The SRQ-20 appears to be a reliable and valid screening measure for depression among rural HIV-positive individuals in southern Uganda. The use of this screening instrument can potentially improve detection and management of depression in this setting.

Adding fuel to the fire: alcohol's effect on the HIV epidemic in Sub-Saharan Africa

Alcohol consumption adds fuel to the HIV epidemic in sub-Saharan Africa (SSA). SSA has the highest prevalence of HIV infection and heavy episodic drinking in the world. Alcohol consumption is associated with behaviors such as unprotected sex and poor medication adherence, and biological factors such as increased susceptibility to infection, comorbid conditions, and infectiousness, which may synergistically increase HIV acquisition and onward transmission. Few interventions to decrease alcohol consumption and alcohol-related sexual risk behaviors have been developed or implemented in SSA, and few HIV or health policies or services in SSA address alcohol consumption. Structural interventions, such as regulating the availability, price, and advertising of alcohol, are challenging to implement due to the preponderance of homemade alcohol and beverage industry resistance. This article reviews the current knowledge on how alcohol impacts the HIV epidemic in SSA, summarizes current interventions and policies, and identifies areas for increased research and development.

Prevalence and factors associated with depressive disorders in an HIV+ rural patient population in southern Uganda

BACKGROUND

Depressive disorders are estimated to occur in nearly half of HIV-infected individuals worldwide.

AIM

To examine the prevalence and cardinal demographic, psychosocial and clinical features associated with having any depressive disorder, sub-clinical depression, current and lifetime depressive disorders among patients with human immunodeficiency virus (HIV) in southern Uganda.

METHODS

Five hundred HIV+ individuals were screened for depression using a 20 item self-reporting questionnaire (SRQ-20) and evaluated with the mini neuropsychiatric interview(MINI) that assessed current and lifetime depressive disorders.

RESULTS

The prevalence estimates of any depressive disorder, subclinical depression, both current and lifetime major depression, and bipolar depression were 46.4%, 17.8%, 25% and 3.6% respectively. In comparison to non-depressed patients, those with sub-clinical depression were less likely to have high levels of self-efficacy, more likely to be using ART for less than one year, have advanced HIV disease and current alcohol use disorders (AUD's). Those with both current and lifetime depressive disorders were less likely to be 85% adherent to antiretroviral therapy (ART), have social support and high levels of self-efficacy, more likely to have tuberculosis and past manic episodes. Those with only lifetime depressive disorders were more likely to have current AUD's and past manic episodes.

LIMITATIONS

Information concerning exposures and outcomes was collected simultaneously, thus causal relationships are difficult to establish.

CONCLUSIONS

Sub-clinical depression, major depression and bipolar depression are widespread among HIV patients receiving ART. Integration of mental health services into HIV Care is desperately needed.

Palliative care and support for persons with HIV/AIDS in 7 African countries: implementation experience and future priorities

To combat morbidity and mortality from the worldwide epidemic of the human immunodeficiency virus (HIV), the United States Congress implemented a President's Emergency Plan for AIDS Relief (PEPFAR) in 30 resource-limited countries to integrate combination antiretroviral therapy (ART) for both prevention and cure. Over 35% of eligible persons have been successfully treated. Initial legislation cited palliative care as an essential aspect of this plan but overall health strengthening became critical to sustainability of programming and funding priorities shifted to assure staffing for care delivery sites; laboratory and pharmaceutical infrastructure; data collection and reporting; and financial management as individual countries are being encouraged to assume control of in-country funding. Given infrastructure requisites, individual care delivery beyond ART management alone has received minimal funding yet care remains necessary for durable viral suppression and overall quality of life for individuals. Technical assistance staff of one implementing partner representing seven African countries met to clarify domains of palliative care compared with the substituted term "care and support" to understand potential gaps in on-going HIV care. They prioritized care needs as: 1) mental health (depression and other mood disorders); 2) communication skills (age-appropriate disclosure of HIV status); 3) support of care-providers (stress management for sustainability of a skilled HIV workforce); 4) Tied Priorities: symptom management in opportunistic infections; end-of-life care; spiritual history-taking; and 5) Tied Priorities: attention to grief-related needs of patients, their families and staff; and management of HIV co-morbidities. This process can inform health policy as funding transitions to new priorities.

Adherence to antiretroviral treatment in HIV-positive patients in the Cameroon context: promoting the use of medication reminder methods

OBJECTIVES

Antiretroviral treatment (ART) scale-up in sub-Saharan Africa has made it possible to investigate the maintenance of adherence to HIV medications. We describe here adherence to ART and identify its correlates in the Cameroonian context.

DESIGN

Prospective cohort study in 9 rural district hospitals.

METHODS

A mixed logistic regression model was used to identify factors associated with adherence to ART in 401 patients with data prospectively collected on adherence.

RESULTS

Although 73% of patients were adherent after the first month on ART, this proportion decreased to 61% after 24 months. After adjustment for known factors of adherence to ART (such as knowledge, motivation and side-effects), patients who reported willingness to start ART before initiation, those who were satisfied with information provided by their physicians, and those who implemented reminder methods for ART intake {eg, using an alarm clock, mobile phone, or watch [odds ratio (95% confidence interval)] = 2.45 (1.58 to 3.79), but also the help of a relative to remind them or other methods} were more likely to be adherent to ART.

CONCLUSIONS

Besides highlighting some correlates already known to have an impact on adherence to ART, our findings also underline the need to reinforce the counseling component of follow-up through innovative methods. Accordingly, training and implementation research should encourage the use of medication reminder methods, such as mobile phones, to assure adherence over time and improve long-term response to ART.

Watering flowers in the rain: The elusive nature of executive dysfunction in HIV

Individuals infected with human immunodeficiency virus (HIV) frequently experience both neurocognitive and psychiatric dysfunction. Apathy is a prominent neuropsychiatric symptom associated with HIV and is related to neurologic dysfunction. In contrast, depression is independent of neurocognitive impairment in HIV. This case report illustrates the importance of behavioral observations from family members of HIV-positive (HIV+) individuals as a valuable source of information. These behavioral observations can be particularly important in rural resource-limited settings, where cognitive testing is often limited to standardized mental status examinations.
