Adherence to highly active antiretroviral therapies (HAART) in HIV-infected patients: from a predictive to a dynamic approach

Neurocognitive, Sociocultural, and Psychological Factors Impacting Medication Beliefs Among HIV-Seropositive Latinx Adults

Among Latinx people living with HIV (PLWH), neurocognitive (NC) function, culture, and mental health impact medication adherence. Similarly, health beliefs and attitudes play a role in health care barriers and health behaviors. Research has not examined the effect that compromised neurocognition, sociocultural factors, and mental health have on health beliefs and attitudes. This is especially relevant for Latinx PLWH who are disproportionately impacted by HIV, given that sociocultural factors may uniquely impact HIV-related NC and psychological sequelae. This study investigated the associations between neurocognition, sociocultural factors, mental health, health beliefs, and health attitudes among Latinx HIV-seropositive adults. Within a sample of 100 Latinx PLWH, better verbal learning and executive functioning abilities were associated with more positive attitudes about the benefits of medications and memory for medications. In terms of sociocultural factors, higher English language competence was related to better self-reported memory for medications, and overall, higher US acculturation was associated with more positive attitudes toward health professionals. Depressive symptomatology was negatively associated with attitudes toward medications and health professionals, as well as with self-reported memory for medications. These findings highlight the important interplay between NC, sociocultural, psychological factors, and health beliefs among Latinx PLWH. Adherence intervention strategies and suggestions for dispensing medical information are presented for clinicians and health care practitioners.

Health Communication Research Informs Inflammatory Bowel Disease Practice and Research: A Narrative Review

Background

In the absence of targeted empirical evidence on effective clinical communication in inflammatory bowel disease (IBD), a broad overview of existing evidence on effective communication in healthcare and available recommendations for communication in telehealth is provided and mapped onto IBD research and practice.

Methods

A narrative literature review was conducted using Pubmed and Scopus databases and snowballing literature search.

Results

Evidence-based relationship building strategies include communicating emotions, acknowledging and addressing patients' hesitancy, and ensuring continued support. A particular recommendation regarding telehealth interaction is to avoid long stretches of talk. Effective informational strategies include facilitating and supporting information exchange and considering patients' preferences in decision-making. In teleconsultations, clinicians should ask direct questions about patients' emotional state, clarify their understanding of patients' concerns and check patients' understanding, address at least one patient-reported outcome when discussing the recommended treatment, and shorten the consultation where possible. Strategies for maximizing effective clinical communication in the spoken communicative mode include using infographics and simple language, and assessing adherence at the beginning of the consultation. For teleconsultations, clinicians are advised to allow patients to explain the reason for their call at the beginning of the teleconsultation, probe additional concerns early and before ending the teleconsultation, and be mindful of technical issues such as voice delays.

Conclusions

Use of question prompt lists, decision aids, micro-lessons, and communication training interventions for clinicians could be beneficial in IBD care. Further research into the implementation of such interventions as well as clinical communication concerns specific to IBD is warranted.

Adherence to Antiretroviral Therapy and Associated Factors Among HIV-Infected Children in Public Health Institutions of Adwa, Axum, and Shire Towns of Tigray, Northern Ethiopia: A Cross-Sectional Study

Background

Antiretroviral therapy (ART) provision was among the major challenge of treatments. Maintaining the optimal level of adherence among children living with HIV/AIDS is a pivotal step towards achieving treatment success. However, there are limited studies on child's ART adherence. Therefore, this study aimed to assess the level of adherence to antiretroviral therapy and associated factors among HIV-infected children in health institutions of Adwa, Axum, and Shire towns, Tigray, Northern Ethiopia.

Methods

An institutional-based cross-sectional study was conducted among human immunodeficiency virus (HIV)-infected children in between February and April, 2016. A total of 255 children who were taking antiretroviral therapy in the randomly selected three health facilities from Adwa, Axum and Shire towns were included. Data were collected using pretested and structured questionnaires using a face-to-face interview. The collected data were entered into Epi Info version 7 and then exported to SPSS version 21 for analysis. Bivariate and multivariate binary logistic regression models were used to determine the factors associated with adherence to antiretroviral therapy among HIV-infected children.

Results

A total of the 255 study participants were included in the study. The level of ART adherence among HIV-positive children was 212 (84.8%). Knowledge of caregivers about ART treatment (AOR = 2.78, 95% CI: 1.18, 6.53), occupational status (AOR = 4.78, 95% CI: 1.26, 18.91), appointment to ART less than two months (AOR = 3.05, 95% CI: 1.21, 7.70) and use of memory aids (AOR = 4.58, 95% CI: 1.73, 12.13) were independently associated with adherence to ART.

Conclusion

The level of adherence to antiretroviral therapy was low. Healthcare providers should reinforce adherence intervention and counseling sessions during follow-up and address the proper use of medication reminders to help children take their drugs appropriately.

Influence of Material Deprivation on Clinical Outcomes Among People Living with HIV in High-Income Countries: A Systematic Review and Meta-analysis

Despite developments in HIV treatment and care, disparities persist with some not fully benefiting from improvements in the HIV care continuum. We conducted a systematic review to explore associations between social determinants and HIV treatment outcomes (viral suppression and treatment adherence) in high-income countries. A random effects meta-analysis was performed where there were consistent measurements of exposures. We identified 83 observational studies eligible for inclusion. Social determinants linked to material deprivation were identified as education, employment, food security, housing, income, poverty/deprivation, socioeconomic status/position, and social class; however, their measurement and definition varied across studies. Our review suggests a social gradient of health persists in the HIV care continuum; people living with HIV who reported material deprivation were less likely to be virologically suppressed or adherent to antiretrovirals. Future research should use an ecosocial approach to explore these interactions across the lifecourse to help propose a causal pathway.

The contexts of housing stability and change among HIV-positive persons in the Lower Manya Krobo Municipality, Ghana

Due to stigma, discrimination and economic insecurity, persons living with HIV/AIDS (PLWHAs) are highly vulnerable to housing instability. For instance, PLWHAs are more likely to either remain stable in inadequate homes or change residence. Yet, few studies explore the contexts of housing stability and change among PLWHAs, especially in sub-Saharan Africa, where the majority reside. This study used qualitative in-depth interviews to explore the narratives of 38 PLWHAs on the contexts of housing stability and the circumstances leading to change in residence. On diagnosis with HIV, the majority of PLWHAs (58%) changed housing locations, mostly from bad to worse conditions. Reasons for change include: eviction due to stigma and discrimination, inability to afford rent, quest to hide HIV status and death of a cohabiting partner. Our findings suggest policy makers should pay attention to the deplorable and poor housing conditions of PLWHAs in Ghana.

Contribution of HIV/AIDS-Related Human and Social Sciences Research to a Better Understanding of the Challenges of Hepatitis B Prevention, Diagnosis and Care

Recent scientific advances in hepatitis B virus research hint at the possibility of finding a cure in the medium term. In this context, the characterization of infected persons constitutes a major public health issue in terms of implementing adapted screening and prevention strategies. Overcoming the current challenges national health systems face in hepatitis B diagnosis is essential if the World Health Organization's target of treating 80% of infected patients by 2030 is to be reached. These challenges reflect those previously faced in the fight against HIV/AIDS. Using the knowledge produced to date in Human and Social Sciences research in the fight against HIV/AIDS, we propose avenues of reflection to support and guide the development of research in the diagnosis of hepatitis B infection. More specifically, we present theoretical, methodological and epistemological considerations for how HSS research can be optimized in the following three HBV diagnosis-related areas: (i) access to screening; (ii) retention in care; and (iii) the integration of quality of life measurement in clinical trials.

The Effect of Partnership Presence and Support on HIV Viral Suppression Among Serodiscordant Partnered and Single Heterosexual HIV-Positive Individuals in Brazil

HIV-negative individuals in serodiscordant partnerships experience reduced risk of HIV acquisition when their partners adhere to ART and achieve undetectable viral loads. Partnership support may encourage ART adherence, reducing viral load and the risk of HIV transmission. This study aims to determine whether HIV viral suppression is associated with partnership status and partnership support among 201 HIV positive (HIV+ individuals in serodiscordant partnerships and 100 HIV+ unpartnered individuals receiving care at Hospital Nossa Senhora da Conceição in Porto Alegre, Brazil between 2014 and 2016. Clinical data and patient-reported questionnaire data were assessed, and propensity scores were used to control for confounding variables in adjusted logistic regression models. Viral suppression did not significantly differ between HIV+ partnered (78.5% virally suppressed) and unpartnered (76.0% virally suppressed) individuals. Among individuals in partnerships, viral suppression was significantly associated with having a partner who attended monthly clinic visits (AOR 2.99; 95% CI 1.00-8.93). Instrumental social support-attending monthly visits-may improve the odds of viral suppression among HIV+ individuals in serodiscordant relationships.

Event-Level Association Between Daily Alcohol Use and Same-Day Nonadherence to Antiretroviral Therapy Among Young Men Who Have Sex With Men and Trans Women Living With HIV: Intensive Longitudinal Study

BACKGROUND

Young trans women (TW) and men who have sex with men (MSM) are disproportionately impacted by HIV. Optimizing adherence to antiretroviral therapy (ART) is one mechanism by which public health experts aim to achieve favorable HIV health outcomes while reducing disease transmission. However, alcohol use is prevalent among young TW and MSM and threatens optimal adherence. In addition, the daily variations in alcohol use and ART adherence and their association with each other are poorly understood, warranting more appropriate methodological approaches, such as analysis of ecological momentary assessment (EMA) data.

OBJECTIVE

The aim of this analysis is to characterize the association between daily alcohol use and same-day ART nonadherence captured by an EMA study of young MSM and TW living with HIV in San Francisco.

METHODS

Young MSM and TW enrolled in the Health eNav digital HIV care navigation intervention were included in the analytic sample (N=113). Data on alcohol and ART use were collected by daily EMA surveys administered via text messaging and were analyzed over 30 days of follow-up. A multivariable mixed-effects logistic regression model adjusting for baseline sociodemographic characteristics was specified to investigate whether daily alcohol use was associated with same-day ART nonuse.

RESULTS

Daily alcohol use was associated with higher same-day ART nonuse. On average, participants drank alcohol on 15.20 (SD 8.93) days and used ART on 15.19 (SD 10.16) days out of 30 days. Daily alcohol use was associated with 1.89 (95% CI 1.14-3.15) times the adjusted odds of same-day ART nonuse for each participant.

CONCLUSIONS

Results are consistent with other analyses of daily alcohol and ART use and underscore the importance of individually targeted interventions that are sensitive to each participant's dynamic risk environment.

Self-Esteem and HIV Infection in Morocco: Associated Factors Among People Living with HIV-Results from a Community-Based Study

People living with HIV (PLHIV) face specific issues regarding mental quality of life (QoL), in particular self-esteem. The objective of this study was to measure self-esteem and to identify associated factors among PLHIV in Morocco. A 125-item questionnaire was administered to 300 PLHIV. The dependent variable was adapted from Rosenberg's self-esteem scale (range 0-4). A weighted multiple linear regression was performed. The mean level of self-esteem was 2.4 ± 1.0. The factors independently associated with self-esteem were: feeling of loneliness (p = 0.001), perceived seriousness of infection (p = 0.006), thinking serostatus disclosure was a mistake (p = 0.007), thinking HIV infection will last for life (p = 0.008), sexual orientation (p = 0.050), satisfaction with sexual life (p = 0.019) and perceived treatment efficacy (p = 0.009). These results underline the need for evidence-based interventions (e.g. anti-discrimination measures, interventions to prevent social isolation of PLHIV, support in the serostatus disclosure process), in order to improve the social environment and eventually improve their self-esteem and QoL.

Attitudes Toward Long-Term Use of Antiretroviral Therapy Among HIV-Infected Pregnant Women in Moshi, Tanzania: A Longitudinal Study

Adherence to antiretroviral therapy (ART) during pregnancy and the postpartum period is necessary to prevent vertical HIV transmission and to secure the long-term health of an HIV-infected woman. Health behavior theory suggests that patients' attitudes towards medication can predict their medication-taking behaviour. This study sought to understand how women's attitudes towards ART changes between the pregnancy and postpartum periods, and the factors associated with these attitudes. The study enrolled 200 pregnant women living with HIV. Structured surveys were administered during pregnancy and at three and 6 months postpartum. Overall, attitudes towards ART were stable over time. More positive attitudes towards ART were associated with HIV acceptance, lower levels of depression, and lower levels of shame. Counselling interventions are needed to help HIV-infected women accept their status and reduce shameful emotions. Depression screening and treatment should be integrated into PMTCT services. This study emphasizes the importance of early attention to attitudes towards ART, in order to establish a trajectory of sustained care engagement.

Depression, Social Support, and Adherence to Antiretroviral Therapy Among People Living With HIV in Guangxi, China: A Longitudinal Study

Depression can result in poor adherence to antiretroviral therapy (ART) among people living with HIV (PLHIV), and social support can help mitigate the negative relationship. However, little is known about how depression and social support synergistically influence ART adherence over time. The current study aims to explore longitudinal associations between them and examine which sources of social support can play a mediating role between depression and ART adherence over time. A randomized controlled clinical trial was conducted between 2013 and 2016 in Guangxi, China. The study sample was composed of 319 PLHIV who were randomized into control condition and provided data at baseline and at least one of the six follow-ups. The results revealed negative associations of depression with ART adherence over time, and a mediating effect of perceived support from spouse/partner or children. Interventions to promote ART adherence should focus on strengthening PLHIV's relationships with their spouse/partner and children, promoting collaborative provider-patient relationships, and enhancing peer support among PLHIV.

Transactional Sex Among Women Accessing Antiretroviral Care in Sagamu, Nigeria: A Descriptive Survey

HIV prevalence and transmission is still of public health concern in low-resource climes like Nigeria. Transactional sex is a well-known risk factor for HIV transmission. This study therefore assessed the prevalence of transactional sex and associated factors among women attending the antiretroviral clinic in Sagamu, Nigeria. A cross-sectional study was carried out among 204 women attending antiretroviral treatment center in Sagamu, Ogun State, Nigeria, selected via total population recruitment. Data were collected using a validated, semistructured questionnaire. Respondents' written informed consent was obtained. The mean age of respondents was 38.3 ± 9.0 years. Two thirds (66%) were in monogamous marriages. About two thirds (64.2%) had at least secondary education. Almost 50% spent more than half of their income on food. About 90% had commenced antiretroviral therapy. The prevalence of transactional sex was 7.4%. Household size ( p = .031), marital status ( p = .015), reduction of food ration ( p = .010), skipping of medication ( p = .001), and starving for a whole day ( p = .044) were associated with transactional sex. Food assistance programs, socioeconomic empowerment schemes, and targeted counseling should be given to people living with HIV to halt HIV transmission.

Discussing HIV Status: Is It Easier After 10 Years of Antiretroviral Treatment? The ANRS CO8 APROCO-COPILOTE Cohort

This study's objective was to explore the factors associated with the belief (or not) by people living with HIV that it is easier to talk about their seropositivity 10 years after initiating a protease inhibitor-containing ART. All patients in the ANRS CO8 APROCO-COPILOTE cohort who completed a self-administered questionnaire at 10 years of follow-up were included in this study. Forty-four percent of patients declared that discussing their seropositivity with their family was easier 10 years later, while 28 % declared this was true for discussing their status with a new sexual partner. Having a low socioeconomic status, not receiving social support from a steady partner and declaring a low number of discomforting symptoms 12 months after PI initiation were all independently associated with less difficulty in discussing seropositivity. This study highlights the difficulties in disclosing HIV 10 years after PI initiation, and the important influence of psychosocial factors and patients' daily-life experience on disclosure.

Illness Representations of HIV Positive Patients Are Associated with Virologic Success

Introduction: It is important for HIV positive patients to be engaged in their care and be adherent to treatment in order to reduce disease progression and mortality. Studies found that illness representations influence adherence through the mediating role of coping behaviors. However, no study has ever tested if patient engagement to the visits mediate the relationship between illness perceptions and adherence. This study aimed to explore illness representations of HIV positive patients and test the hypothesis that illness representations predict adherence through the mediating role of a component of behavioral engagement. Methods: HIV-positive patients treated with highly active antiretroviral therapy (HAART) for at least one year and presenting to a check-up visit were eligible to participate in the study. Patients completed the Illness Perception Questionnaire-Revised. Behavioral engagement was measured based on the patients' clinical attendance to the check-up visits; adherence to HAART was measured by viral load. Undetectable viral load or HIV-RNA < 40 copies/ml were considered indexes of virologic success. Results: A total of 161 patients participated in the study. Most of them coherently attributed the experienced symptoms to HIV/HAART; perceived their condition as chronic, stable, coherent, judged the therapy as effective, and attributed their disease to the HIV virus and to their behavior or bad luck. The majority of patients (80.1%) regularly attended check-up visits and 88.5% of them reached virologic success. The mediation model did not show good fit indexes. However, a significant direct effect of two independent variables on virologic success was found. Specifically, the perception that the disease does not have serious consequences on patient's life and the prevalence of negative emotions toward HIV were associated with virologic success. On the contrary, the patient's perception that the disease has serious consequences on his/her life and the prevalence of positive emotions were associated with virologic failure. This model showed good fit indexes (CFI = 1; TLI = 1; RMSEA = 0.00; and WRMSR = 0.309). Discussion: Results do not support the mediating role of behavioral engagement in the relationship between illness representations and adherence. As perception of serious consequences coupled with positive emotions are directly associated with virologic failure, clinicians should take them into account to promote treatment adherence.

Counselling Psychology in South Africa

The origin and development of counselling psychology in South Africa has been profoundly influenced by the country's socio-political history and the impact of apartheid. As a result of this, counselling psychologists in the country face a number of challenges and opportunities for the future. In this paper we provide a portrait of counselling psychology in South Africa by describing the current character of the specialty and the context in which South African psychologists work. We critically discuss the challenges that the specialty faces to meet the country's mental health care needs, contest the current Scope of Practice; affirm multiculturalism without essentializing or reifying race and ethnicity, and build an evidence base for community interventions in the country. We also consider how, in the future, counselling psychologists in South Africa may make a more meaningful contribution within public health and the country's health care and education systems.

The Clarification of Depression and Social Support's Contribution to the Prediction of Antiretroviral Medication Adherence and the Rate of CD4 in People with HIV

With the development of the antiretroviral therapy, the number of the people with HIV is increasing; therefore, identifying the factors affecting HIV is of great importance. This study aimed to investigate the relationship between the antiretroviral medication adherence and the rate of CD4 with depression and social support in the people with HIV. The research method was a descriptive study kind of correlation. The statistical population included all patients with HIV in Shiraz, of whom, 220 people who had referred to the Behavioral Diseases Consultation Center were selected using the available sampling method. Philips et al.'s Social Support Questionnaire, Beck's Depression Questionnaire II, and ACTG Medication Adherence Questionnaire were used as the research tools. Results were analyzed using the stepwise regression and stepwise hierarchical multiple regression. Regression analysis showed that social support and depression variables could predict totally 47% (P<0.001) of changes of medication adherence variable, and depression could predict only 2% (P<0.01) of rate variance of CD4.

Exploring the Interaction between Comorbid Psychiatric and Medical Diagnoses: The Potential Impact of Borderline Personality Disorder on Adherence to Highly Active Antiretroviral Therapy (HAART)

It is well documented that patient adherence to medical advice and prescription medication is suboptimal. While the reasons for non-compliance are varied and complex, it is essential that they be expounded to facilitate the efficacy of medical interventions. In no other illness is this more pertinent than with the human immunodeficiency virus (HIV). Highly active antiretroviral therapy (HAART) has become the first line of treatment for HIV, but stringent adherence is a prerequisite for therapeutic efficacy. As with other treatments, adherence to HAART is problematic. One factor that may play a significant role is if the patient has a comorbid psychiatric illness. This article provides a theoretical exposition of how a patient with Borderline Personality Disorder (BPD) might suffer innumerable exigencies with adherence as a hypothesised function of the individual properties of his or her illness that is likely to be compounded when the properties interact with one another.

Supportive Relationships and Medication Adherence in HIV-Infected, Low-Income Latinos

Inadequate social support and poor communications with health care providers can affect adherence to antiretroviral therapy. The magnitude of independent effects of these factors on adherence is not fully known. This study examined the relationship of perceived emotional or informational social support from family and friends, quality of physician-patient communications and relationships, and medication adherence in a sample of low-income, Spanishspeaking, HIV-positive Latino men and women receiving treatment in community-based clinics (n = 85). Results of the study indicated that, whereas emotional or informational support was significantly associated with level of dose adherence (OR, 1.04, 95% CI, 1.01-1.08;p = .03), quality of physician-patient communications or relationships was significantly associated with adherence to medication schedule,t (6, 71) = 4.45,p < .001. Quality of patient-physician relationship accounted for 22% of the variance in adherence to medication schedule. Both kinds of support were associated with better adherence in this population but may affect adherence behaviors in different ways.

Socioeconomic status and response to antiretroviral therapy in high-income countries: a literature review

It has been shown that socioeconomic factors are associated with the prognosis of several chronic diseases; however, there is no recent systematic review of their effect on HIV treatment outcomes. We aimed to review the evidence regarding the existence of an association of socioeconomic status with virological and immunological response to antiretroviral therapy (ART). We systematically searched the current literature using the database PubMed. We identified and summarized original research studies in high-income countries that assessed the association between socioeconomic factors (education, employment, income/financial status, housing, health insurance, and neighbourhood-level socioeconomic factors) and virological response, immunological response, and ART nonadherence among people with HIV-prescribed ART. A total of 48 studies met the inclusion criteria (26 from the United States, six Canadian, 13 European, and one Australian), of which 14, six, and 35 analysed virological, immunological, and ART nonadherence outcomes, respectively. Ten (71%), four (67%), and 23 (66%) of these studies found a significant association between lower socioeconomic status and poorer response, and none found a significant association with improved response. Several studies showed that adjustment for nonadherence attenuated the association between socioeconomic status and ART response. Our review provides strong support that socioeconomic disadvantage is associated with poorer response to ART. However, most studies have been conducted in settings such as the United States without universal free healthcare access. Further study in settings with free access to ART could help assess the impact of socioeconomic status on ART outcomes and the mechanisms by which it operates.

HIV/AIDS Competent Households: Interaction between a Health-Enabling Environment and Community-Based Treatment Adherence Support for People Living with HIV/AIDS in South Africa

In the context of severe human resource shortages in HIV care, task-shifting and especially community-based support are increasingly being cited as potential means of providing durable care to chronic HIV patients. Socio-ecological theory clearly stipulates that-in all social interventions-the interrelatedness and interdependency between individuals and their immediate social contexts should be taken into account. People living with HIV/AIDS (PLWHA) seldom live in isolation, yet community-based interventions for supporting chronic HIV patients have largely ignored the social contexts in which they are implemented. Research is thus required to investigate such community-based support within its context. The aim of this study is to address this research gap by examining the way in which HIV/AIDS competence in the household hampers or facilitates community-based treatment adherence support. The data was analyzed carefully in accordance with the Grounded Theory procedures, using Nvivo 10. More specifically, we analyzed field notes from participatory observations conducted during 48 community-based treatment adherence support sessions in townships on the outskirts of Cape Town, transcripts of 32 audio-recorded in-depth interviews with PLWHA and transcripts of 4 focus group discussions with 36 community health workers (CHWs). Despite the fact that the CHWs try to present themselves as not being openly associated with HIV/AIDS services, results show that the presence of a CHW is often seen as a marker of the disease. Depending on the HIV/AIDS competence in the household, this association can challenge the patient's hybrid identity management and his/her attempt to regulate the interference of the household in the disease management. The results deepen our understanding of how the degree of HIV/AIDS competence present in a PLWHA's household affects the manner in which the CHW can perform his or her job and the associated benefits for the patient and his/her household members. In this respect, a household with a high level of HIV/AIDS competence will be more receptive to treatment adherence support, as the patient is more likely to allow interaction between the CHW and the household. In contrast, in a household which exhibits limited characteristics of HIV/AIDS competence, interaction with the treatment adherence supporter may be difficult in the beginning. In such a situation, visits from the CHW threaten the hybrid identity management. If the CHW handles this situation cautiously and the patient-acting as a gate keeper-allows interaction, the CHW may be able to help the household develop towards HIV/AIDS competence. This would have a more added value compared to a household which was more HIV/AIDS competent from the outset. This study indicates that pre-existing dynamics in a patient's social environment, such as the HIV/AIDS competence of the household, should be taken into account when designing community-based treatment adherence programs in order to provide long-term quality care, treatment and support in the context of human resource shortages.

Housing Status, Medical Care, and Health Outcomes Among People Living With HIV/AIDS: A Systematic Review

BACKGROUND

Accumulating evidence suggests responses to HIV that combine individual-level interventions with those that address structural or contextual factors that influence risks and health outcomes of infection. Housing is such a factor. Housing occupies a strategic position as an intermediate structural factor, linking "upstream" economic, social, and cultural determinants to the more immediate physical and social environments in which everyday life is lived. The importance of housing status for HIV prevention and care has been recognized, but much of this attention has focused on homeless individuals as a special risk group. Analyses have less often addressed community housing availability and conditions as factors influencing population health or unstable, inadequate, or unaffordable housing as a situation or temporary state. A focus on individual-level characteristics associated with literal homelessness glosses over social, economic, and policy drivers operating largely outside any specific individual's control that affect housing and residential environments and the health resources or risk exposures such contexts provide.

OBJECTIVES

We examined the available empirical evidence on the association between housing status (broadly defined), medical care, and health outcomes among people with HIV and analyzed results to inform future research, program development, and policy implementation.

SEARCH METHODS

We searched 8 electronic health and social science databases from January 1, 1996, through March 31, 2014, using search terms related to housing, dwelling, and living arrangements and HIV and AIDS. We contacted experts for additional literature.

SELECTION CRITERIA

We selected articles if they were quantitative analyses published in English, French, or Spanish that included at least 1 measure of housing status as an independent variable and at least 1 health status, health care, treatment adherence, or risk behavior outcome among people with HIV in high-income countries. We defined housing status to include consideration of material or social dimensions of housing adequacy, stability, and security of tenure.

DATA COLLECTION AND ANALYSIS

Two independent reviewers performed data extraction and quality appraisal. We used the Cochrane Risk of Bias Tool for randomized controlled trials and a modified version of the Newcastle Ottawa Quality Appraisal Tool for nonintervention studies. In our quality appraisal, we focused on issues of quality for observational studies: appropriate methods for determining exposure and measuring outcomes and methods to control confounding.

RESULTS

Searches yielded 5528 references from which we included 152 studies, representing 139,757 HIV-positive participants. Most studies were conducted in the United States and Canada. Studies examined access and utilization of HIV medical care, adherence to antiretroviral medications, HIV clinical outcomes, other health outcomes, emergency department and inpatient utilization, and sex and drug risk behaviors. With rare exceptions, across studies in all domains, worse housing status was independently associated with worse outcomes, controlling for a range of individual patient and care system characteristics.

CONCLUSIONS

Lack of stable, secure, adequate housing is a significant barrier to consistent and appropriate HIV medical care, access and adherence to antiretroviral medications, sustained viral suppression, and risk of forward transmission. Studies that examined the history of homelessness or problematic housing years before outcome assessment were least likely to find negative outcomes, homelessness being a potentially modifiable contextual factor. Randomized controlled trials and observational studies indicate an independent effect of housing assistance on improved outcomes for formerly homeless or inadequately housed people with HIV. Housing challenges result from complex interactions between individual vulnerabilities and broader economic, political, and legal structural determinants of health. The broad structural processes sustaining social exclusion and inequality seem beyond the immediate reach of HIV interventions, but changing housing and residential environments is both possible and promising.

Does Food Insecurity Undermine Adherence to Antiretroviral Therapy? A Systematic Review

A growing body of research has identified food insecurity as a barrier to antiretroviral therapy (ART) adherence. We systematically reviewed and summarized the quantitative literature on food insecurity or food assistance and ART adherence. We identified nineteen analyses from eighteen distinct studies examining food insecurity and ART adherence. Of the thirteen studies that presented an adjusted effect estimate for the relationship between food insecurity and ART adherence, nine found a statistically significant association between food insecurity and sub-optimal ART adherence. Four studies examined the association between food assistance and ART adherence, and three found that ART adherence was significantly better among food assistance recipients than non-recipients. Across diverse populations, food insecurity is an important barrier to ART adherence, and food assistance appears to be a promising intervention strategy to improve ART adherence among persons living with HIV. Additional research is needed to determine the effectiveness and cost-effectiveness of food assistance in improving ART adherence and other clinical outcomes among people living with HIV in the era of widespread and long-term treatment.

Psychiatric symptoms and antiretroviral nonadherence in US youth with perinatal HIV: a longitudinal study

OBJECTIVES

The relationship of specific psychiatric conditions to adherence has not been examined in longitudinal studies of youth with perinatal HIV infection (PHIV). We examined associations between psychiatric conditions and antiretroviral nonadherence over 2 years.

DESIGN

Longitudinal study in 294 PHIV youth, 6-17 years old, in the United States and Puerto Rico.

METHODS

We annually assessed three nonadherence outcomes: missed above 5% of doses in the past 3 days, missed a dose within the past month, and unsuppressed viral load (>400 copies/ml). We fit multivariable logistic models for nonadherence using Generalized Estimating Equations, and evaluated associations of psychiatric conditions (attention deficit hyperactivity disorder, disruptive behavior, depression, anxiety) at entry with incident nonadherence using multivariable logistic regression.

RESULTS

Nonadherence prevalence at study entry was 14% (3-day recall), 32% (past month nonadherence), and 38% (unsuppressed viral load), remaining similar over time. At entry, 38% met symptom cut-off criteria for at least one psychiatric condition. Greater odds of 3-day recall nonadherence were observed at week 96 for those with depression [adjusted odds ratio (aOR) 4.14, 95% confidence interval (CI) 1.11-15.42] or disruptive behavior (aOR 3.36, 95% CI 1.02-11.10], but not at entry. Those with vs. without attention deficit hyperactivity disorder had elevated odds of unsuppressed viral load at weeks 48 (aOR 2.46, 95% CI 1.27-4.78) and 96 (aOR 2.35, 95% CI 1.01-5.45), but not at entry. Among 232 youth adherent at entry, 16% reported incident 3-day recall nonadherence. Disruptive behavior conditions at entry were associated with incident 3-day recall nonadherence (aOR 3.01, 95% CI 1.24-7.31).

CONCLUSION

In PHIV youth, comprehensive adherence interventions that address psychiatric conditions throughout the transition to adult care are needed.

Long-term postpartum adherence to antiretroviral drugs among women in Latin America

Antiretroviral adherence in the postpartum period is crucial for maternal health and decreasing the risk of mother-to-child HIV transmission and transmission to sexual partners. Self-reported antiretroviral adherence was examined between 6- to 12-weeks and 30 months postpartum among 270 HIV-infected women enrolled in a prospective cohort study from 2008 to 2010 at multiple sites in Latin America. Adherence data were collected at each study visit to quantify the proportion of prescribed antiretrovirals taken during the previous three days, assess the timing of the last missed dose, and identify predictors of adherence. Mean adherence rates were 89.5% at 6-12 weeks and 92.4% at 30 months; the proportions with perfect adherence were 80.3% and 83.6%, respectively. The overall trend for perfect adherence was not significant (p = 0.71). In adjusted regression modelling, younger age was associated with an increased probability of non-perfect adherence at 18 and 24 months postpartum. Other factors associated with increased probability of non-perfect adherence were higher parity, current use of alcohol and tobacco, and more advanced HIV disease. Women with perfect adherence had lower viral loads. Interventions for alcohol and tobacco use cessation, and support for young women and those with advanced HIV disease should be considered to improve postpartum adherence.

[Factors associated with non-adherence of adults infected with HIV on antiretroviral therapy in a referral hospital in Douala]

Introduction

Le succès du traitement antirétroviral repose sur l'observance. Elle est nécessaire pour réduire la mortalité, diminuer le risque de résistance et restaurer l'immunité. Cette étude a pour but d'identifier et analyser les différents facteurs associés à la non observance thérapeutique des patients infectés par le VIH sous traitement antirétroviraux à l'hôpital de référence Laquintinie de Douala.

Méthodes

Il s'agit d'une étude transversale et analytique effectuée de mars à juin 2014. La non observance est mesurée à travers les déclarations du patient et sur consultation des registres de renouvellement des ordonnances. Etaient non observant, ceux ayant consommé moins de 95% de médicaments et ceux ne s’étant pas présentés pour le renouvellement de l'ordonnance. L'analyse bivariée et le modèle de régression logistique ont été utilisés pour la détermination des facteurs associés à la non observance.

Résultats

Au total, 524 patients ont été enrôlés dans l’étude;l’âge moyen était de 43,0 ± 10,7 ans et le sexe ratio H/F de 0,54. De ces patients, 49,0% étaient non observant, majoritairement des femmes (61,9%). Les principales raisons avancées de la non observance sont: l'oubli (32,9%), la rupture de médicaments (14,0%), les occupations (12,8%). Les personnes veuves(IC 95% OR= 1,31-5,22, p= 0,006), la consommation des excitants (IC 95%, OR= 2,30-6,90, p= 0,0001) et la présence d'infection opportuniste (IC 95%, OR= 1,41-17,54, p= 0,01) ont fortement été associés à la non observance.

Conclusion

Le taux d'observance était faible, lié à plusieurs facteurs. Des mesures sont nécessaires pour résoudre ce problème, y compris des stratégies tendant à l'amélioration du soutien psycho-social, et la limitation des ruptures de stock de médicaments. La recherche qualitative est souhaitée pour comprendre les raisons de la non observance afin de mettre au point des interventions fondées sur des données probantes.

Antiretroviral Treatment Adherence Rate and Associated Factors among People Living with HIV in Dubti Hospital, Afar Regional State, East Ethiopia

Introduction. Antiretroviral Therapy has transformed HIV infection into a chronic manageable disease; it requires near perfect adherence rates (as high as 95%). In this study, we assessed antiretroviral treatment adherence rate and associated factors among people living with HIV in Dubti Hospital. Methods. A retrospective cross-sectional study design was conducted within February 1-30, 2014. All HIV-infected patients above the age of 18 years who took first line Antiretroviral Therapy were eligible for inclusion of the study. Adherence Scale was used for labeling patients as adherent or nonadherent. All HIV-infected patients record data were collected from the medical records, entered, and analyzed using Epi Info 7 and SPSS Version 20. Multivariable analysis was used to identify the relative effect of explanatory variables on low adherence rate. Results. A total of 370 patients aged 18 years and above, who started ART, were included in this study. The self-reported adherence rate of the patient on ART was 81.1%. Independent predictors of adherence were treatment duration. Conclusion. Adherence rate was associated with time to ART. That is, the longer they were on ART, the lesser they adhered.

The relationship of CSF and plasma cytokine levels in HIV infected patients with neurocognitive impairment

Although HAD is now rare due to HAART, the milder forms of HAND persist in HIV-infected patients. HIV-induced systemic and localized inflammation is considered to be one of the mechanisms of HAND. The levels of cytokines in CSF were associated with neurocognitive impairment in HIV infection. However, the changes of cytokines involved in cognition impairment in plasma have not been shown, and their relationships between CSF and plasma require to be addressed. We compared cytokine levels in paired CSF and plasma samples from HIV-infected individuals with or without neurocognitive impairment. Cytokine concentrations were measured by Luminex xMAP. In comparing the expression levels of cytokines in plasma and CSF, IFN-α2, IL-8, IP-10, and MCP-1 were significantly higher in CSF. Eotaxin was significantly higher in plasma, whereas G-CSF showed no difference between plasma and CSF. G-CSF (P = 0.0079), IL-8 (P = 0.0223), IP-10 (P = 0.0109), and MCP-1 (P = 0.0497) in CSF showed significant difference between HIV-CI and HIV-NC group, which may indicate their relationship to HIV associated neurocognitive impairment. In addition, G-CSF (P = 0.0191) and IP-10 (P = 0.0377) in plasma were significantly higher in HIV-CI than HIV-NC. The consistent changes of G-CSF and IP-10 in paired plasma and CSF samples might enhance their potential for predicting HAND.

Correlates of unstructured antiretroviral treatment interruption in a cohort of HIV-positive individuals in British Columbia

Treatment interruptions (TIs) limit the therapeutic success of combination antiretroviral therapy and are associated with higher morbidity and mortality. HIV-positive individuals dealing with concurrent health issues, access challenges and competing life demands are hypothesized to be more likely to interrupt treatment. Individuals were included if they initiated cART ≥1 year prior to interview date and had a CD4 cell count and initial regimen recorded at initiation. Using pharmacy recording, a TI was defined as a patient-initiated gap in treatment ≥90 consecutive days during the 12 months preceding or following the study interview. 117 (15.2 %) of 768 participants included in this study had a TI during the study window. 76.0 % of participants were male, 27.5 % were of Aboriginal ancestry and the median age was 46 (interquartile range 40-52). In multivariable logistic regression, TIs were significantly associated with current illicit drug use (adjusted odds ratio [aOR] 1.68, 95 % confidence interval [CI] 1.05-2.68); <95 % adherence in the first year of treatment (aOR 2.68, 95 % CI 1.67-4.12); living with at least one person (aOR 1.95; 95 % CI 1.22-3.14) or living on the street (aOR 5.08, 95 % CI 1.72-14.99) compared to living alone; poor perception of overall health (aOR 1.64 95 % CI 1.05-2.55); being unemployed (aOR: 2.22, 95 % CI 1.16-4.23); and younger age at interview (aOR 0.57, 95 % CI 0.44-0.75, per 10 year increase). Addressing socioeconomic barriers to treatment retention is vital for supporting the continuous engagement of patients in care.

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.

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.

Virus against virus (VIVI): a potential solution against HIV/AIDS

Most therapeutic regimens are aimed at the use of pharmacologic agents or the induction of immunological response against the pathological agent. However, these methods tend to be insufficient for the management of some of the most debilitating infectious diseases. Here we present a novel therapeutic approach. It involves voluntary super-infection of a subject having HIV/AIDS with a virus (GBV-C), which to date has not been shown to be responsible for any pathology. It has been shown to counter, suppress or eradicate the agent responsible for the severe disease. Several studies demonstrate the role of different micro-organisms in influencing the growth of other pathogens in the human body. This hypothesis requires meticulous testing before its implementation on humans. If the trials are successful, the implications for this hypothesis are promising considering the compliance issues and adverse effects associated with current standard of HIV care.

Antiretroviral treatment and quality of life in Africans living with HIV: 12-month follow-up in Burkina Faso

Introduction

The scale-up of highly active antiretroviral therapy (HAART) has led to a significant improvement in survival of the HIV-positive patient but its effects on health-related quality of life (HRQOL) are less known and context-dependent. Our aim was to assess the temporal changes and factors associated with HRQOL among HIV-positive adults initiating HAART in Burkina Faso.

Methods

HIV-positive people initiating HAART were prospectively included and followed over a one-year period in three HIV clinics of Ouagadougou. HRQOL was assessed at baseline and at each follow-up visit using physical (PHS) and mental (MHS) summary scores derived from the Medical Outcome Study 36-Item short-form health survey (MOS SF-36) questionnaire. Toxicity related to HAART modification and self-reported symptoms were recorded during follow-up visits. Determinants associated with baseline and changes in both scores over a one-year period were assessed using a mixed linear model.

Results

A total of 344 patients were included. Their median age at baseline was 37 years [interquartile range (IQR) 30–44] and their median CD4 count was 181 cells/mm³ (IQR 97–269). The mean [standard deviation (SD)] PHS score increased from 45.4 (11.1) at baseline to 60.0 (3.1) at 12 months (p<10⁻⁴) and the mean (SD) MHS score from 42.2 (8.7) to 43.9 (3.4) (p<10⁻²). After one year of treatment, patients that experienced on average two symptoms during follow-up presented with significantly lower PHS (63.9) and MHS (43.8) scores compared to patients that presented no symptoms with PHS and MHS of 68.2 (p<10⁻⁴) and 45.3 (p<10⁻³), respectively.

Discussion

The use of HAART was associated with a significant increase in both physical and mental aspects of the HRQOL over a 12-month period in this urban African population. Perceived symptoms experienced during follow-up visits were associated with a significant impairment in HRQOL. The appropriate and timely management of reported symptoms during the follow-up of HAART-treated patients is a key component to restore HRQOL.

Incidence and predictive factors of depression among patients with HIV infection in Guadeloupe: 1988-2009

A retrospective cohort study was conducted to determine the incidence and the predictive factors of depression in a cohort of 2737 HIV/AIDS-infected patients in Guadeloupe followed for a total of 8402 patient-years. The incidence rate of first observed depression was 2.2 per 100 person-years (95% confidence interval [CI], 1.9-2.6). A single failure Cox proportional hazards model showed that the 1997-2000 inclusion period (hazard ratio [HR] = 1.60; 95% CI = 1.10-2.40;p = 0.01), the 2001-2009 inclusion period (HR = 1.50; 95% CI = 1.02-2.40;p = 0.04), the more advanced CDC stage (HR = 2.30; 95% CI = 1.30-3.10;p = 0.000) and the annual frequency of visits > 10 (HR = 2.30; 95% CI = 1.70-3.30;p = 0.000) were associated with an increased risk of depression. Incidence of depression in this HIV cohort was high and the hazard function showed three peaks of depression (2, 7 and 12 years). Physicians should be vigilant to psychological distress throughout life with HIV.

Impact of HIV-related stigma on treatment adherence: systematic review and meta-synthesis

Introduction

Adherence to HIV antiretroviral therapy (ART) is a critical determinant of HIV-1 RNA viral suppression and health outcomes. It is generally accepted that HIV-related stigma is correlated with factors that may undermine ART adherence, but its relationship with ART adherence itself is not well established. We therefore undertook this review to systematically assess the relationship between HIV-related stigma and ART adherence.

Methods

We searched nine electronic databases for published and unpublished literature, with no language restrictions. First we screened the titles and abstracts for studies that potentially contained data on ART adherence. Then we reviewed the full text of these studies to identify articles that reported data on the relationship between ART adherence and either HIV-related stigma or serostatus disclosure. We used the method of meta-synthesis to summarize the findings from the qualitative studies.

Results

Our search protocol yielded 14,854 initial records. After eliminating duplicates and screening the titles and abstracts, we retrieved the full text of 960 journal articles, dissertations and unpublished conference abstracts for review. We included 75 studies conducted among 26,715 HIV-positive persons living in 32 countries worldwide, with less representation of work from Eastern Europe and Central Asia. Among the 34 qualitative studies, our meta-synthesis identified five distinct third-order labels through an inductive process that we categorized as themes and organized in a conceptual model spanning intrapersonal, interpersonal and structural levels. HIV-related stigma undermined ART adherence by compromising general psychological processes, such as adaptive coping and social support. We also identified psychological processes specific to HIV-positive persons driven by predominant stigmatizing attitudes and which undermined adherence, such as internalized stigma and concealment. Adaptive coping and social support were critical determinants of participants’ ability to overcome the structural and economic barriers associated with poverty in order to successfully adhere to ART. Among the 41 quantitative studies, 24 of 33 cross-sectional studies (71%) reported a positive finding between HIV stigma and ART non-adherence, while 6 of 7 longitudinal studies (86%) reported a null finding (Pearson's χ²=7.7; p=0.005).

Conclusions

We found that HIV-related stigma compromised participants’ abilities to successfully adhere to ART. Interventions to reduce stigma should target multiple levels of influence (intrapersonal, interpersonal and structural) in order to have maximum effectiveness on improving ART adherence.

Adherence to antiretroviral drug therapy in adult patients who are HIV-positive in Northwest Ethiopia: a study protocol

INTRODUCTION

Achievement of optimal medication adherence and management of antiretroviral toxicity pose great challenges among Ethiopian patients with HIV/AIDS. There is currently a lack of long-term follow-up studies that identify the barriers to, and facilitators of, adherence to antiretroviral therapy (ART) in the Ethiopian setting. Therefore, we aim to investigate the level of adherence to ART and a wide range of potential influencing factors, including adverse drug reactions occurring with ART.

METHODS AND ANALYSIS

We are conducting a 1-year prospective cohort study involving adult patients with HIV/AIDS starting on ART between December 2012 and March 2013. Data are being collected on patients' appointment dates in the ART clinics. Adherence to ART is being measured using pill count, medication possession ratio and patient's self-report. The primary outcome of the study will be the proportion of patients who are adherent to their ART regimen at 3, 6 and 12 months using pill count. Taking 95% or more of the dispensed ART regimen using pill count at given points of time will be considered the optimal level of adherence in this study. Data will be analysed using descriptive and inferential statistical procedures.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Tasmania Health and Medical Human Research Ethics Committee and Bahir-Dar University's Ethics Committee. The results of the study will be reported in peer-reviewed scientific journals, conferences and seminar presentations.

An exploratory study on the mental health of immigrants, refugees and non-status people living with HIV in Toronto

Purpose

– Canadian HIV/AIDS researchers, service providers and policy-makers are faced with new challenges of providing effective and inclusive care that meets the needs of the changing populations infected with and affected by HIV. Since 2005 immigrants and refugees from ethno-racial minority communities have comprised close to 20 percent of all new HIV infections in Canada. Anecdotes shared by PLWHAs and service providers indicated that mental health challenges faced by newcomer PLWHAs was a priority concern for HIV prevention, treatment and care. This paper reports on the results of an exploratory study, which examined the complex factors that influence the mental health of immigrants and refugees living with HIV/AIDS (IR-PLWHAs).

Design/methodology/approach

– This exploratory study is informed by a critical social science paradigm, which acknowledges that the everyday reality is shaped by interlocking systems of social processes and unequal power relations. The paper used a qualitative interpretative design and focus groups to explore the intersecting effects of living with HIV/AIDS, migration and settlement, and HIV stigma and discrimination on the mental health of IR-PLWHAs.

Findings

– The paper found that in addition to social and economic marginalization, IR-PLWHAs experienced multiple stressors associated with their HIV status: neurocognitive and physical impairments, HIV stigma and discrimination, and fear of deportation. The paper also found that the experiences of stigma and discrimination among IR-PLWHAs were complex and contextual, closely linked to their social positions defined by the intersecting dimensions of race, class, gender, citizenship, sexualities, body norms, and HIV status. The paper concludes that effective HIV prevention, treatment and care, and mental health promotion in newcomer and ethno-racial minority communities must consider the bio-psycho-social connections of different stressors and the interlocking systems of oppression faced by IR-PLWHAs.

Research limitations/implications

– This study was exploratory in nature with a small number of participants who were recruited through AIDS organizations in Toronto. Consequently, the recruitment strategy may reach only those who were connected to the AIDS organizations. The paper believes that IR-PLWHAs who were not connected to the AIDS organizations might experience even more social exclusion and marginalization. These factors may limit the transferability of this study.

Originality/value

– This is the first study that explores the bio-psycho-social connections and intersecting determinants of mental health among immigrants and refugees living with HIV and AIDS in Canada. The results of this study contribute to cross-sector dialogue among practitioners and researchers in the HIV/AIDS, mental health, and immigration and settlement services sectors.

Incidence rate of modifying or discontinuing first combined antiretroviral therapy regimen due to toxicity during the first year of treatment stratified by age

Toxicity is the most frequently reported reason for modifying or discontinuing the first combined antiretroviral therapy regimens, and it can cause significant morbidity, poor quality of life and also can be an important barrier to adherence, ultimately resulting in treatment failure and viral resistance. Elderly patients with HIV/AIDS (≥50 years) may have a different profile in terms of treatment modification due to higher incidence of comorbidities and polypharmacy. The aim of this study was to describe the incidence of modifying or discontinuing first combined antiretroviral therapy regimen due to toxicity (TOX-MOD) during the first year of treatment at the IPEC – FIOCRUZ HIV/AIDS cohort, Rio de Janeiro, Brazil, stratified by age. Demographic, clinical and treatment characteristics from antiretroviral-naïve patients who first received combined antiretroviral therapy between Jan/1996 and Dec/2010 were collected. Incidence rate and confidence interval of each event were estimated using quasipoisson model. To estimate hazard ratio (HR) of TOX-MOD during the first year of combined antiretroviral therapy Cox's proportional hazards regression was applied. Overall, 1558 patients were included; 957 (61.4%), 420 (27.0%) and 181 (11.6%) were aged <40, 40–49, and ≥50 years, respectively. 239 (15.3%) events that led to any modifying or discontinuing within the first year of treatment were observed; 228 (95.4%) of these were TOX-MOD, corresponding to an incidence rate of 16.6/100 PY (95% CI: 14.6–18.9). The most frequent TOX-MOD during first combined antiretroviral therapy regimen were hematologic (59; 26.3%), central nervous system (47; 20.9%), rash (42; 19.1%) and gastrointestinal (GI) (38; 16.7%). In multivariate analysis, incidence ratio of TOX-MOD during the first year of combined antiretroviral therapy progressively increases with age, albeit not reaching statistical significance. This profile was maintained after adjusting the model for sex, combined antiretroviral therapy regimen and year of combined antiretroviral therapy initiation. These results are important because not only patients are living longer and aging with HIV, but also new diagnoses are being made among the elderly. Prospective studies are needed to evaluate the safety profile of first line combined antiretroviral therapy on elderly individuals, especially in resource-limited countries, where initial regimens are mostly NNRTI-based.

Assessing adherence to antiretroviral therapy in randomized HIV clinical trials: a review of currently used methods

Antiretroviral therapy for the treatment of HIV infection requires high levels of adherence to both maintain plasma HIV RNA at undetectable levels and prevent the emergence of drug resistance. As adherence to treatment is a major criterion for the evaluation of therapeutic outcomes, randomized clinical trials (RCTs) conducted among HIV-infected patients commonly include an assessment of adherence. However, there is still no gold-standard tool for assessing adherence behaviors in HIV RCTs. The methods currently used to collect and analyze adherence data are varied, which makes the comparison of results between studies difficult. The scope of this article is to review and discuss the range of adherence measures currently used in RCTs conducted among HIV-infected adults.

Toward the integration of comprehensive mental health services in HIV care: an assessment of psychiatric morbidity among HIV-positive individuals in sub-Saharan Africa

Existing evidence from research supports the desirability of integration of mental health services into HIV care in order to mitigate the grave consequences of unattended mental health morbidity among People Living with HIV/AIDS (PLWHA). This study aims to find out the burden and pattern of psychiatric disorders that is prevalent among HIV-positive individuals attending a Nigerian-based HIV clinic. The study participants, consisting of 295 HIV-positive adults were recruited using systematic random sampling method. The participants were subjected to questionnaire to elicit demographic profile and General Health Questionnaire (GHQ-28) to screen for probable psychiatric disorders. This was followed by Structured Clinical Interview for DSM-IV Non patient (SCID-NP) to diagnose the presence of psychiatric morbidity in any of the participant with a GHQ-28 score ≥5 and 10% of those with GHQ-28 score <5. Data were analyzed with SPSS 17. Of the 295 participants interviewed, approximately one-quarter (25.1%) of the participants had diagnosable psychiatric illness based on SCID-NP. Depression was the commonest mental disorder detected as 44 (14.9%) met the DSM-IV Axis 1 diagnosis of major depressive disorders. Anxiety disorders, concurrent Nicotine with Alcohol dependence and cannabis abuse were elicited in 24 (8.1%), 4 (1.3%), and 2 (0.7%) participants, respectively. This study finds a higher burden of psychiatric disorders in PLWHA in comparison to what is obtainable in the general population based on previous research works in similar context. Thus further underscores the need for integration of comprehensive psychiatric services into HIV care. We advocate the support and commitment of key stakeholders in HIV care to the translation of this research-based evidence into practice among PLWHA.

Housing characteristics and their influence on health-related quality of life in persons living with HIV in Ontario, Canada: results from the positive spaces, healthy places study

Although lack of housing is linked with adverse health outcomes, little is known about the impacts of the qualitative aspects of housing on health. This study examined the association between structural elements of housing, housing affordability, housing satisfaction and health-related quality of life over a 1-year period. Participants were 509 individuals living with HIV in Ontario, Canada. Regression analyses were conducted to examine relationships between housing variables and physical and mental health-related quality of life. We found significant cross-sectional associations between housing and neighborhood variables-including place of residence, housing affordability, housing stability, and satisfaction with material, meaningful and spatial dimensions of housing-and both physical and mental health-related quality of life. Our analyses also revealed longitudinal associations between housing and neighborhood variables and health-related quality of life. Interventions that enhance housing affordability and housing satisfaction may help improve health-related quality of life of people living with HIV.

In-home mental health treatment for individuals with HIV

Mental health problems are highly prevalent among individuals with HIV and are consistently associated with negative health outcomes. However, mental illness often remains untreated due to significant psychosocial and physical barriers to treatment participation. The Collaborative HIV/AIDS Mental Health Program (CHAMP) assessed the outcomes associated with providing 9 months of in-home mental health counseling for 40 individuals with HIV and a Major Axis I mental disorder. The evidence-based Illness Management and Recovery Model was adapted for use with HIV-positive individuals for the study using a community-based participatory research approach. Study participants were surveyed at baseline, 5 and 9 months to assess for changes in health outcomes. Thirty-five percent of study participants were female, 80% African American, 33% self-identified as MSM and the average participant age was 43. Forty percent of participants were on psychotropic medication at baseline. Participants had an average of 8 counseling visits (median 9). Statistically significant decreases in the global Brief Symptom Inventory (BSI) score and a number of BSI symptoms dimensions including anxiety, depression, obsessive compulsive, phobic anxiety and hostility were detected, indicating a reduction of psychiatric symptoms. Statistically significant improvement was also identified for the SF-12 mental health scale, adaptive coping, overall social support and emotional support. No differences in psychiatric outcomes were identified by gender, race/ethnicity, or sexual preference. Findings from the CHAMP Study suggest that the use of in-home mental health treatment may be beneficial in engaging and treating HIV-positive individuals with comorbid mental health disorders.
