Medication Adherence and Health Outcomes of People Living with HIV Who Are Food Insecure and Prescribed Antiretrovirals That Should Be Taken with Food

Adherence to oral antiretroviral therapy in Canada, 2010-2020

OBJECTIVE

To assess antiretroviral therapy (ART) adherence among people with HIV (PWH) in Canada and identify baseline characteristics associated with suboptimal adherence (<95%).

DESIGN

Retrospective observational study using data from the National Prescription Drug Utilization Information System and Régie de l'assurance maladie Quebec (RAMQ) Public Prescription Drug Insurance Plan.

METHODS

This analysis included PWH aged 18 years or older who initiated an ART regimen and were followed for at least 12 months (2010-2020). Patient characteristics were summarized using medical/pharmacy claims data from seven provinces (Alberta, Manitoba, New Brunswick, Newfoundland and Labrador, Ontario, Saskatchewan, and Quebec). ART regimen at index date (first dispensing of a regimen including a core agent) was defined as a single-tablet or multitablet regimen (MTR). Adherence was calculated using a Proportion of Days Covered approach, based on ART dispensing, recorded between April 2010 and the last available date. Multivariate linear regression analysis was used to determine correlations between suboptimal adherence and baseline characteristics.

RESULTS

We identified 19 322 eligible PWH, 44.7% of whom had suboptimal adherence (<95%). Among 12 594 PWH with evaluable baseline data, 10 673 (84.8%) were ART-naive, 74.2% were men, mean age was 42.9 years, and 54.1% received a MTR as their ART. Based on multivariate regression analysis, suboptimal adherence was significantly associated with multitablet ART ( P  < 0.001) and younger age ( P  < 0.001) but not sex.

CONCLUSION

Almost half of adult PWH in Canada had suboptimal adherence to ART. Better understanding of factors influencing adherence may help address gaps in current care practices that may impact adherence.

The impact of food insecurity on receipt of care, retention in care, and viral suppression among people living with HIV/AIDS in the United States: a causal mediation analysis

Introduction

Attaining The Joint United Nations Programme on HIV/AIDS 95-95-95 targets to end the HIV epidemic by 2030 will require a greater understanding of the underlying mechanisms influencing care engagement among people living with HIV/AIDS (PLWHA). One such mechanism is food insecurity, defined as limited or uncertain access to food. Food insecurity has been shown to significantly impact HIV outcomes. Yet, few studies have examined the mechanisms through which food insecurity may influence these outcomes. We aimed to examine the effects of nutritional, behavioral, and mental health mechanisms through which food insecurity may impact HIV care continuum outcomes: receipt of care, retention in care, and viral suppression.

Methods

We conducted a cross-sectional study of 200 PLWHA in New York State, United States from May-August 2022. Participants were recruited using convenience sampling methods. Multivariable logistic regression models were conducted to examine the associations between food insecurity and care continuum outcomes (receipt of care, retention in care, viral suppression), adjusting for age, race, ethnicity, education, income, and marital status. Individual causal mediation analyses were conducted to assess whether behavioral, mental health, and nutritional mechanisms mediated the hypothesized associations.

Results

The median age of participants was 30 years (IQR: 27-37 years). The majority self-identified as Black (54.0%), male (55.5%) and straight/heterosexual (63.0%). Increasing severity of food insecurity was associated with greater odds of non-retention in care (aOR: 1.35, 95% CI: 1.07, 1.70) and viral non-suppression (aOR: 1.29, 95% CI: 1.08, 1.54). For the impact of food insecurity on non-retention in care, there was an indirect relationship (natural indirect effect; NIE) mediated through Body Mass Index (BMI) (ORNIE: 1.08, 95% CI: 1.00, 1.18). For viral non-suppression, there was an indirect relationship mediated through BMI (ORNIE: 1.07, 95% CI: 1.00,1.16) and an indirect relationship mediated through depression (ORNIE: 1.27, 95% CI: 1.07, 1.47).

Discussion

Food insecurity was associated with greater odds of non-retention in care and viral non-suppression among PLWHA. Nutritional and mental health pathways are important mediators of these relationships. Results highlight the need for interventions to target these pathways to address food insecurity as an underlying mechanism influencing engagement in HIV care.

Adolescent Girls and Young Women's Experiences of Living with HIV in the Context of Patriarchal Culture in Sub-Saharan Africa: A Scoping Review

Adolescent girls and young women (AGYW) in sub-Saharan Africa are disproportionately affected by the human immunodeficiency virus (HIV) due to socio-cultural gender, power, and economic disparities. This scoping review examined the literature to explore what is known about AGYW's everyday personal, relational, and social experiences of HIV to help shape future protective HIV policy and practice. Six databases were searched: Medline, CINAHL, Scopus, ASSIA, Google Scholar, and ProQuest, resulting in a total of 12,581 articles. Of these, 40 articles were included in the review. Key themes generated from the thematic analysis were relational and psychosocial challenges, inhibiting sexual expression, poverty, stigma, and discrimination; managing health in everyday life; agency and resilience; and personal space and social support. In conclusion, the review found a lack of understanding of AGYW's everyday experiences of living with HIV from their own perspectives. There was also little consideration of the role of patriarchal culture and how this constrains AGYW's ability to negotiate their relationships. Further research is needed to reveal AGYW's perspectives on living with HIV in sub-Saharan Africa.

Senior food insecurity in the USA: a systematic literature review

OBJECTIVE

Understanding the factors associated with senior food insecurity is key to understanding senior-specific needs to develop targeted interventions and ultimately lower the prevalence and the incidence of food insecurity. We aimed to systematically review published literature and summarise the associated factors of food insecurity in older adults in the USA.

DESIGN

We searched PubMed, Scopus, Web of science, EconLit and JSTOR databases for peer-reviewed articles published in English between January 2005 and September 2019 that assessed food security or its associated factors for US adults aged 60 years and older. After a two-step screening process, twenty articles were retained and included in the review.

SETTING

NA.

PARTICIPANTS

NA.

RESULTS

The majority of studies were cross-sectional (70 %), consisted of data from one state (60 %), and had large sample sizes. Food-insecure individuals were more likely to be younger, less educated, Black or African American, female, a current smoker, low income, and self-report fair/poor health, have chronic conditions, and utilise government assistance programmes. Food insecurity was associated with medication non-adherence, poor mental health outcomes and limitations in physical functioning. Results were mixed for overweight/obesity status. There was no discernable pattern related to the consistency of findings by the assessed quality of the included studies.

CONCLUSIONS

Food insecurity is a prevalent and pervasive issue for older adults. The numerous correlates identified suggest that interventions aimed at enhancing food and nutrition safety net and medication assistance programmes are warranted, and upstream, systemic-level interventions may be best suited to deal with the correlates of food insecurity.

Exploring antiretroviral therapy adherence, competing needs, and viral suppression among people living with HIV and food insecurity in the Dominican Republic

Understanding factors related to suboptimal adherence to antiretroviral therapy (ART) and detectable viral load (VL), especially among vulnerable populations, is needed to improve HIV outcomes. The Caribbean is highly impacted by HIV and socioeconomic inequalities, but few studies have been conducted there to explore food insecurity among people with HIV and factors associated with viral suppression in this vulnerable population. Using baseline data from a pilot intervention trial among people living with HIV and food insecurity in the Dominican Republic, we examined psychosocial and behavioral factors associated with viral suppression, ART adherence, and competing needs. Among participants (n = 115), 61% had a detectable VL; the strongest factor associated with detectable VL was having missed taking ART in the last six months due to not having food (OR = 2.68, p = 0.02). Greater odds of reporting missed ART doses due to not having food were associated with severe food insecurity (OR = 4.60, p = 0.006), clinical depression (OR = 2.76, p = 0.018), Haitian background (OR = 6.62 p = 0.017), and internalized HIV stigma (OR = 1.09, p = 0.041), while lower odds were associated with social support (OR = 0.89, p = 0.03) and having health insurance (OR = 0.27, p = 0.017). Ensuring that people with HIV and food insecurity have food to take with their ART is essential for viral suppression.

Economic Burden Among Gay, Bisexual, and Other Men Who Have Sex With Men Living With HIV or Living Without HIV in the Multicenter AIDS Cohort Study

With HIV now considered a chronic disease, economic burden for people living with HIV (LWH) may threaten long-term disease outcomes. We studied associations between economic burden (employment, income, insurance, and financial difficulty) and HIV status for gay, bisexual, and other men who have sex with men (GBMSM) and how economic burden relates to disease progression.

Treatment Satisfaction and Its Associated Factors of Dolutegravir Based Regimen in a Resource Limited Setting

INTRODUCTION

Treatment satisfaction is patient's evaluation of the process of taking the medication and its use. Currently dolutegravir based regimen is first-line agent for treatment of human immunodeficiency virus. But evidence is scarce regarding treatment satisfaction. Thus, the aim of the current study was to assess treatment satisfaction and associated factors of dolutegravir based regimen among adult human immunodeficiency virus patients attending at Debre Markos referral 2020.

METHODS

Institutional-based cross-sectional study was conducted. A systematic random sampling technique was used to collect data from June 25 to August 25, 2020 at Debre Markos referral hospital. It was entered into Epi Info and exported to SPSS version 23 for analysis. Bivariable and multivariable logistic regression was used to identify factors. Variables with p<0.05 were considered as statistically significant.

RESULTS

From a total of 359, 349 participants (97.2%) responded to the study. In this study, 70.5% of participants reported higher treatment satisfaction. Monthly average income of ≥3500 birr (AOR: 2.88; 95% CI: 1.26, 6.58), 1600-2500 birr (AOR: 2.47; 95% CI: 1.11, 5.48), 800-1600 birr (AOR: 3.11; 95% CI: 1.31, 7.37), positive belief about medications (AOR: 3.05; 1.76, 5.28), having a discussion with health care providers (AOR: 3.05, 95% CI: 1.58, 5.88), patients without concurrent medication (AOR: 7.72, 95% CI: 3.29, 18.07), and being male (AOR: 2.10, 95% CI: 1.14, 3.87) were associated with treatment satisfaction.

CONCLUSION

Overall, dolutegravir based regimen showed high treatment satisfaction. Monthly income, positive beliefs about medications, discussing about treatment options, sex and concurrent medications were associated with treatment satisfaction. Thus, it is crucial to improve treatment satisfaction by promoting positive belief towards medication and also by engaging patients in treatment decisions.

Promoters and inhibitors of treatment adherence among HIV/AIDS patients receiving antiretroviral therapy in Ghana: Narratives from an underserved population

Adherence to antiretroviral therapy (ART) is essential to achieving an improved cluster of differentiation-4 (CD4) count, viral load, and quality of life while preventing drug resistance. Medication adherence among people living with Human Immunodeficiency Virus (HIV) is influenced by different factors. Several studies have identified adherence promoters and inhibitors that emanate from the internal and external environment. We conducted six (6) individual in-depth interviews and three (3) focus group discussions to explore adherence behaviour among patients diagnosed with HIV in a teaching hospital in Accra, Ghana. Participants were drawn from the intervention arm of a mobile phone adherence intervention program. They had been enrolled in the study for at least six (6) months before the interviews are conducted. Results revealed that participants adhered to treatment irrespective of prompts from significant others. Adherence promoters included perception of ART as part of daily routines, benefits of the ART, awareness of regimen, access to food, and transparency. Adherence inhibitors were forgetfulness, secrecy, waiting time, religious beliefs, and sleep. People living with HIV (PLWHIV) have the personal motivation to take medication; however, negative perceptions about HIV must be addressed to ensure optimum adherence behaviour.

Health professionals' experiences and perspectives on food insecurity and long-term conditions: A qualitative investigation

Estimates suggest that over 10% of the UK population are affected by food insecurity. International evidence indicates that food insecurity is a risk factor for many long-term health conditions, and can adversely affect people's ability to manage existing conditions. Food insecurity is thus not only a serious social concern but also a healthcare issue requiring the attention of UK health professionals. An exploratory qualitative study was undertaken to investigate the experiences and views of health professionals in north east Scotland, with a particular focus on support for people with long-term conditions whom they believed were affected by food insecurity. Two focus groups and nine semi-structured interviews were undertaken with a total of 20 health professionals between March and July 2016. Thematic analysis generated three main themes. The health professionals had (a) diverse levels of understanding and experience of food insecurity, but between them identified a range of (b) negative impacts of food insecurity on condition-management, especially for diet dependent conditions or medication regimes, and for mental health. Even for those health professionals more familiar with food insecurity, there were various (c) practical and ethical uncertainties about identifying and working with food insecure patients (it could be difficult to judge, for example, whether and how to raise the issue with people, to tailor dietary advice to reflect food insecurity, and to engage with other agencies working to address food insecurity). This study indicates that health professionals working with food insecure patients have learning and support needs that warrant further investigation. Debates about health professionals' responsibilities, and interventions to guide and support health professionals, including tools that might be used to screen for food insecurity, must also reflect the diverse lived needs and values of people who experience food insecurity.

The long-term effects of a family based economic empowerment intervention (Suubi+Adherence) on suppression of HIV viral loads among adolescents living with HIV in southern Uganda: Findings from 5-year cluster randomized trial

BACKGROUND

The rapid scale-up of HIV therapy across Africa has failed to adequately engage adolescents living with HIV (ALWHIV). Retention and viral suppression for this group (ALWHIV) is 50% lower than for adults. Indeed, on the African continent, HIV remains the single leading cause of mortality among adolescents. Strategies tailored to the unqiue developmental and social vulnerabilities of this group are urgently needed to enhance successful treatment.

METHODS

We carried out a five-year longitudinal cluster randomized trial (ClinicalTrials.gov ID: NCT01790373) with adolescents living with HIV (ALWHIV) ages 10 to 16 years clustered at health care clinics to test the effect of a family economic empowerment (EE) intervention on viral suppression in five districuts in Uganda. In total, 39 accredited health care clinics from study districts with existing procedures tailored to adolescent adherence were eligible to participate in the trial. We used data from 288 youth with detectable HIV viral loads (VL) at baseline (158 -intervention group from 20 clinics, 130 -non-intervention group from 19 clinics). The primary end point was undetectable plasma HIV RNA levels, defined as < 40 copies/ml. We used Kaplan-Meier (KM) analysis and Cox proportional hazard models to estimate intervention effects.

FINDINGS

The Kaplan-Meier (KM) analysis indicated that an incidence of undetectable VL (0.254) was significantly higher in the intervention condition compared to 0.173 (in non-intervention arm) translated into incidence rate ratio of 1.468 (CI: 1.064-2.038), p = 0.008. Cox regression results showed that along with the family-based EE intervention (adj. HR = 1.446, CI: 1.073-1.949, p = 0.015), higher number of medications per day had significant positive effects on the viral suppression (adj.HR = 1.852, CI: 1.275-2.690, p = 0.001).

INTERPRETATION

A family economic empowerment intervention improved treatment success for ALWHIV in Uganda. Analyses of cost effectiveness and scalability are needed to advance incorporation of this intervention into routine practice in low and middle-income countries.

Assessing the impact of food insecurity on HIV medication adherence in the context of an integrated care programme for people living with HIV in Vancouver, Canada

OBJECTIVE

Food insecurity, or self-reports of inadequate food access due to limited financial resources, remains prevalent among people living with HIV (PLHIV). We examined the impact of food insecurity on combination antiretroviral therapy (cART) adherence within an integrated care programme that provides services to PLHIV, including two meals per day.

DESIGN

Adjusted OR (aOR) were estimated by generalized estimating equations, quantifying the relationship between food insecurity (exposure) and cART adherence (outcome) with multivariable logistic regression.

SETTING

We drew on survey data collected between February 2014 and March 2016 from the Dr. Peter Centre Study based in Vancouver, Canada.

PARTICIPANTS

The study included 116 PLHIV at baseline, with ninety-nine participants completing a 12-month follow-up interview. The median (quartile 1-quartile 3) age was 46 (39-52) years at baseline and 87 % (n 101) were biologically male at birth.

RESULTS

At baseline, 74 % (n 86) of participants were food insecure (≥2 affirmative responses on Health Canada's Household Food Security Survey Module) and 67 % (n 78) were adherent to cART ≥95 % of the time. In the adjusted regression analysis, food insecurity was associated with suboptimal cART adherence (aOR = 0·47, 95 % CI 0·24, 0·93).

CONCLUSIONS

While food provision may reduce some health-related harms, there remains a relationship between this prevalent experience and suboptimal cART adherence in this integrated care programme. Future studies that elucidate strategies to mitigate food insecurity and its effects on cART adherence among PLHIV in this setting and in other similar environments are necessary.

Necessity and concerns beliefs and HIV medication adherence: a systematic review

According to the Necessity-Concerns Framework, beliefs about medication necessity and concerns are two core themes from diverse patient medication beliefs across chronic illnesses that may directly influence adherence. Past work has supported associations of necessity and concerns to adherence in the chronic disease literature and in HIV research. However, there has not been a focused review of the literature on associations of necessity and concerns to HIV medication adherence, nor on what variables may influence these associations. This systematic review synthesized findings from 26 studies regarding associations of necessity and concerns to HIV medication adherence. Both beliefs showed small, clinically significant effects on adherence. A subset of studies identified perceptions of healthcare providers as determinants of necessity and concerns beliefs with indirect effects on adherence. Overall, necessity and concerns demonstrated clinically significant associations to adherence among people with HIV.

Food Insecurity and Unmet Needs Among Youth and Young Adults Living With HIV in the San Francisco Bay Area

PURPOSE

Little is known about food insecurity and unmet subsistence needs and their association with antiretroviral therapy adherence among youth and young adults living with HIV (YLWH).

METHODS

We conducted a cross-sectional survey to examine this association in 101 YLWH (aged 18-29 years). Poisson regression models with robust standard errors were used to estimate adjusted risk ratios (RRs) and 95% confidence intervals (CIs).

RESULTS

Approximately 51.7% of participants experienced at least one unmet subsistence need (difficulty finding enough to eat [36.6%], clothing [22.8%], place to sleep [21.8%], place to wash [17.8%], and bathroom [15.8%]), and 64.2% reported being food insecure. For every additional unmet need, the risk of very good/excellent adherence was reduced by 15% (RR = .85; 95% CI = .72-.99; p value = .04). The risk of very good/excellent adherence was lowered by 39% (RR = .61; 95% CI = .43-.87; p value = .005) among food insecure youth, compared with those who were food secure.

CONCLUSIONS

These data highlight the need for more research and structural interventions targeting food assistance strategies among YLWH.

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.

HIV-Related Stress and Life Chaos Mediate the Association Between Poverty and Medication Adherence Among People Living with HIV/AIDS

HIV treatment depends on high-levels of antiretroviral therapy (ART) adherence, which is severely impeded by poverty. Men and women living with HIV infection (N = 92) completed computerized interviews of demographic and health characteristics, poverty markers, stressful life events, and life chaos, as well as unannounced pill counts to determine prospective medication adherence and medical record chart abstractions for HIV viral load. Poverty markers were associated with both stressors and chaos, and the direct effects of all three factors predicted ART non-adherence. The multiple mediation model showed that accounting for stressors and chaos resulted in a non-significant association between poverty markers and ART adherence. The indirect effect of poverty markers on adherence through life chaos was significant, whereas the indirect effect of poverty markers on adherence through stressors was not significant. Factors that render HIV-related stress and create chaos offer intervention targets that are more amenable to change than poverty itself.

The Daily Relationship Between Aspects of Food Insecurity and Medication Adherence Among People Living with HIV with Recent Experiences of Hunger

BACKGROUND

Limited access to resources can significantly impact health behaviors. Previous research on food insecurity and HIV has focused on establishing the relationship between lacking access to nutritious food and antiretroviral (ARV) medication non-adherence in a variety of social contexts.

PURPOSE

This study aims to determine if several aspects of food insecurity co-occur with missed doses of medication on a daily basis among a sample of people living with HIV who have recently experienced hunger.

METHODS

The current study utilized a prospective, observational design to test the daily relationship between food insecurity and medication non-adherence. Participants were followed for 45 days and completed daily assessments of food insecurity and alcohol use via interactive text message surveys and electronic medication adherence monitoring using the Wisepill.

RESULTS

Fifty-nine men and women living with HIV contributed a total of 2,655 days of data. Results showed that severe food insecurity (i.e., hunger), but not less severe food insecurity (i.e., worrying about having food), significantly predicted missed doses of medication on a daily level. Daily alcohol use moderated this relationship in an unexpected way; when individuals were hungry and drank alcohol on a given day, they were less likely to miss a dose of medication.

CONCLUSIONS

Among people living with HIV with recent experiences of hunger, this study demonstrates that there is a daily relationship between hunger and non-adherence to antiretroviral therapy. Future research is needed to test interventions designed to directly address the daily relationship between food insecurity and medication non-adherence.

Food Insecurity, HIV Disease Progression and Access to Care Among HIV-Infected Russians not on ART

Food insecurity (FI) has been associated with HIV disease progression among people on antiretroviral therapy (ART), presumably a consequence of poor medication adherence. We assessed whether there is a longitudinal association between FI and two primary outcomes reflecting on HIV disease progression (i.e., CD4 count and time to ART initiation) among people not on ART. Analyses used linear mixed effects and Cox models controlling for confounders. In this cohort (n = 310) FI was common (53%). Most (71.3%) reported past month heavy alcohol use and 37.1% reported past month injection drug use. Only 50 participants initiated ART during the study and mean time to ART was 128 days (SD 120). There were no significant differences in CD4 cell count between the groups with mild/moderate FI or severe FI versus those with no FI [adjusted mean difference, mild/moderate insecurity versus no FI -32.5 (95% CI -94.3, 29.3); severe versus no FI -45.5 (95% CI -124.1, 33.0); global p = 0.42]. We found no significant association between FI and longer time to ART initiation (p = 0.36). Food security is a desirable goal for overall health and shown beneficial for those on ART, however it does not appear to be associated with HIV disease progression among those with high prevalence of substance use and not yet on ART.

Food insecurity may lead to incomplete HIV viral suppression and less immune reconstitution among HIV/hepatitis C virus-coinfected people

OBJECTIVES

The aim of this study was to determine the impact of food insecurity (FI) on HIV viral load and CD4 count among people coinfected with HIV and hepatitis C virus (HCV).

METHODS

This study was conducted using data from the Food Security & HIV-HCV Sub-Study of the Canadian Co-Infection Cohort study. FI was measured using the adult scale of Health Canada's Household Food Security Survey Module and was classified into three categories: food security, moderate food insecurity and severe food insecurity. The association between FI, HIV viral load, and CD4 count was assessed using a stabilized inverse probability weighted marginal structural model.

RESULTS

A total of 725 HIV/HCV-coinfected people with 1973 person-visits over 3 years of follow-up contributed to this study. At baseline, 23% of participants experienced moderate food insecurity and 34% experienced severe food insecurity. The proportion of people with undetectable HIV viral load was 75% and the median CD4 count was 460 [interquartile range (IQR): 300-665] cells/μL. People experiencing severe food insecurity had 1.47 times [95% confidence interval (CI): 1.14, 1.88] the risk of having detectable HIV viral load and a 0.91-fold (95% CI: 0.84, 0.98) increase in CD4 count compared with people who were food secure.

CONCLUSIONS

These findings provide evidence of the negative impact of food insecurity on HIV viral load and CD4 count among HIV/HCV-coinfected people.

Drug interactions and the role of pharmacokinetic trials in guiding choices in first-line HIV therapy in low-income and middle-income countries

PURPOSE OF REVIEW

Low- and middle-income countries (LMICs) face specific challenges in the treatment of people living with HIV. Drug-drug interactions (DDIs) involving antiretrovirals (ARVs) are prevalent in all settings and have considerable potential to cause clinical harm to patients via toxicity or reduced efficacy of treatment. Differing comorbidities, endemic infections and traditional medicines may complicate ARV therapy (ART) in LMICs, which usually takes a public health approach in these settings, with fewer alternative regimens available. This review discusses the issues surrounding pharmacokinetic DDI studies and their application to ART in LMICs, with particular reference to first-line ART regimens.

RECENT FINDINGS

Pharmacokinetic studies with clinical endpoints are the gold standard for informing management of DDIs; however, data relevant to LMICs are sparse and of low quality. There is significant potential for clinically relevant DDIs between ARVs and antimalarials, antimycobacterials and drugs used in the treatment of neglected tropical diseases.

SUMMARY

Many pharmacokinetic studies are difficult to interpret in LMICs due to differences in patient factors including weight, disease state and genetic polymorphisms. DDI studies relevant to LMICs may also be lacking due to the neglected nature of relevant comorbidities. The ARVs currently available as first-line ART in LMICs are among those with highest propensity for DDIs.

Would I take antipsychotics, if I had psychotic symptoms? Examining determinants of the decision to take antipsychotics

Poor adherence to treatment in schizophrenia is mainly associated to patients-related factors. However, social negative representations of schizophrenia and its treatment may also contribute to patients' decision to take or not to take antipsychotics. A web-based study on 1,807 participants was conducted during which participants imagined that they had a particular chronic illness based on clinical vignettes (mental illnesses: schizophrenia, depression; somatic illnesses: multiple sclerosis, rheumatoid arthritis). Participants rated their subjective distress and perceived social stigma associated with each illness. They also rated the perceived treatability of the illness, their belief in the effectiveness of treatment, and their treatment preference regarding medication. Results show that schizophrenia was considered more distressful, less treatable and associated with higher social stigma than somatic illnesses. Medication was less preferred for treating schizophrenia compared to somatic illnesses. Perceived treatability of illness and belief in the effectiveness of pharmacological treatment were the factors driving preference for medication in schizophrenia and depression, respectively; these factors had weaker influence on preference for medication in somatic illnesses. Our study points out more severe negative representations of mental illnesses in general, and their treatment, particularly schizophrenia. These attitudes are not confined to patients, and may influence patients' decisions to take psychotropic drugs.

Missed Initial Medical Visits: Predictors, Timing, and Implications for Retention in HIV Care

HIV disproportionately affects racial/ethnic minorities and individuals living in the southern United States, and missed clinic visits account for much of this disparity. We sought to evaluate: (1) predictors of missed initial HIV medical visits, (2) time to initial visit, and (3) the association between initial visit attendance and retention in HIV care. Chart reviews were conducted for 200 consecutive HIV-infected patients (100 in Dallas, 100 in San Antonio) completing case management (CM) intake. Of these, 52 (26%) missed their initial visit, with 22 (11%) never presenting for care. Mean age was 40 years, 85% were men, >70% were of minority race/ethnicity, and 28% had a new HIV diagnosis. Unemployment (OR [95% CI] = 2.33 [1.04-5.24], p = 0.04) and lower attendance of CM visits (OR = 3.08 [1.43-6.66], p = 0.004) were associated with missing the initial medical visit. A shorter time to visit completion was associated with CD4 ≤ 200 (HR 1.90 [1.25-2.88], p = 0.003), Dallas study site (HR = 1.48 [1.03-2.14], p = 0.04), and recent hospitalization (HR = 2.18 [1.38-3.43], p < 0.001). Patients who did not complete their initial medical visit within 90 days of intake were unlikely to engage in care. Initial medical visit attendance was associated with higher proportion of visits attended (p = 0.04) and fewer gaps in care (p = 0.01). Missed medical visits were common among HIV patients initiating or reinitiating care in Texas. Employment and CM involvement predicted initial medical visit attendance, which was associated with retention in care. New, early engagement strategies are needed to decrease missed visits and reduce HIV health disparities.

Household food insecurity among people living with HIV in Sagamu, Nigeria: A preliminary study

BACKGROUND

Household food insecurity has been associated with increased risk of transmission of HIV infection and poor treatment outcomes. This study therefore determined the prevalence of household food insecurity and its associated factors among people living with HIV in Sagamu, Ogun State, Nigeria.

METHODS

A cross-sectional descriptive study was carried out among 244 adult clients accessing care and support at the teaching hospital in Sagamu, Nigeria, selected via systematic sampling. Data was collected with the aid of a semi-structured, interviewer-administered questionnaire. Data was analysed using SPSS 21.0. Relevant descriptive and inferential statistics were calculated. Informed consent was obtained and strict confidentiality was ensured.

RESULTS

The mean age of respondents was 38.8 ± 9.2 years; 84% of respondents were female; 69.3% were married, 12.9% had lost their partners. About 12% spent more than three-quarters of the household income on food. The prevalence of household food insecurity was 71.7%. Food insecurity was associated ( p < 0.05) with educational status; occupation; type of housing; availability of toilet facilities; benefiting from food assistance; delaying drugs to prevent hunger; skipping drugs; vegetable consumption pattern; and exchanging sex for food.

CONCLUSION

The prevalence of household food insecurity in this study was high. Living conditions were significantly associated with food insecurity. Socio-economic conditions need to be improved, to optimize the health and food security status of people living with HIV in Sagamu.

Psychosocial correlates of nutritional status among people living with HIV on antiretroviral therapy: A matched case-control study in Central zone of Tigray, Northern Ethiopia

BACKGROUND

Malnutrition hastens progression to Acquired Human Immunodeficiency Syndromes (AIDS) related illnesses; undermines adherence and response to antiretroviral therapy (ART) in resource-poor settings. However, nutritional status of people living with HIV (PLHIV) can be affected by various psychosocial factors which have not been well explored in Ethiopia. Therefore, the objective of this study was to determine psychosocial correlates of nutritional status among people living with HIV (PLHIV) on ART in Central zone of Tigray, Northern Ethiopia.

METHODS

A matched case-control study design was conducted to assess psychosocial correlates of nutritional status among PLHIV on ART. Data were collected by an interviewer-administered technique using structured pre-tested questionnaire, record review using a checklist and anthropometric measurements. Cases were selected by simple random sampling and controls purposively to match the selected cases. Conditional logistic regression was used to compute relevant associations by STATA version 12.

RESULTS

The psychosocial factors independently associated with malnutrition were ever consuming alcohol after starting ART [AOR = 4.7, 95% CI: 1.8-12.3], ever smoking cigarette after starting ART [AOR = 7.6, 95% CI: 2.3-25.5], depression [AOR = 2.8, 95% CI: 1.3, 6.1], not adhering to ART [AOR = 6.8,95% CI: 2.0-23.0] and being in the second lowest wealth quintile [AOR = 4.3,95% CI: 1.1-17.7].

CONCLUSION

Ever consuming alcohol and ever smoking cigarette after starting ART, depression, not adhering to ART and being in the second lowest wealth quintile were significantly associated with malnutrition. Therefore; policies, strategies, and programs targeting people living with HIV should consider psychosocial factors that can impact nutritional status of people living with HIV enrolled on ART.

Association Between Food Insecurity and HIV Viral Suppression: A Systematic Review and Meta-Analysis

Although an increasing number of HIV infected people are accessing antiretroviral treatment, many do not achieve complete HIV viral suppression and remain at risk for AIDS and capable of HIV transmission. Food insecurity has been identified as a potential risk factor for poor virologic response, but the association between these factors has been inconsistently documented in the literature. We systematically searched five electronic databases and bibliographies of relevant studies through April 2015 and retrieved 11 studies that met our inclusion criteria, of which nine studies were conducted in North America and the remaining two studies were in Brazil and Uganda respectively. Meta-analyzed results indicated that experiencing food insecurity resulted in 29% lower odds of achieving complete HIV viral suppression (OR = 0.71, 95% CI 0.61-0.82) and this significant inverse association was consistently found regardless of study design, exposure measurement, and confounder adjustment methods. These findings suggest that food insecurity is a potential risk factor for incomplete HIV viral suppression in people living with HIV.

Socioeconomic status and treatment outcomes for individuals with HIV on antiretroviral treatment in the UK: cross-sectional and longitudinal analyses

Background

Few studies have assessed the effect of socioeconomic status on HIV treatment outcomes in settings with universal access to health care. Here we aimed to investigate the association of socioeconomic factors with antiretroviral therapy (ART) non-adherence, virological non-suppression, and virological rebound, in HIV-positive people on ART in the UK.

Methods

We used data from the Antiretrovirals, Sexual Transmission Risk and Attitudes (ASTRA) questionnaire study, which recruited participants aged 18 years or older with HIV from eight HIV outpatient clinics in the UK between Feb 1, 2011, and Dec 31, 2012. Participants self-completed a confidential questionnaire on sociodemographic, health, and lifestyle issues. In participants on ART, we assessed associations of financial hardship, employment, housing, and education with: self-reported ART non-adherence at the time of the questionnaire; virological non-suppression (viral load >50 copies per mL) at the time of questionnaire in those who started ART at least 6 months ago (cross-sectional analysis); and subsequent virological rebound (viral load >200 copies per mL) in those with initial viral load of 50 copies per mL or lower (longitudinal analysis).

Findings

Of the 3258 people who completed the questionnaire, 2771 (85%) reported being on ART at the time of the questionnaire, and 2704 with complete data were included. 873 (32%) of 2704 participants reported non-adherence to ART and 219 (9%) of 2405 had virological non-suppression in cross-sectional analysis. Each of the four measures of lower socioeconomic status was strongly associated with non-adherence to ART, and with virological non-suppression (prevalence ratios [PR] adjusted for gender/sexual orientation, age, and ethnic origin: greatest financial hardship vs none 2·4, 95% CI 1·6–3·4; non-employment 2·0, 1·5–2·6; unstable housing vs homeowner 3·0, 1·9–4·6; non-university education 1·6, 1·2–2·2). 139 (8%) of 1740 individuals had subsequent virological rebound (rate=3·6/100 person-years). Low socioeconomic status was predictive of longitudinal rebound risk (adjusted hazard ratio [HR] for greatest financial hardship vs none 2·3, 95% CI 1·4–3·9; non-employment 3·0, 2·1–4·2; unstable housing vs homeowner 3·3, 1·8–6·1; non-university education 1·6, 1·1–2·3).

Interpretation

Socioeconomic disadvantage was strongly associated with poorer HIV treatment outcomes in this setting with universal health care. Adherence interventions and increased social support for those most at risk should be considered.

Brief Report: Food Insufficiency Is Associated With Lack of Sustained Viral Suppression Among HIV-Infected Pregnant and Breastfeeding Ugandan Women

Supplemental Digital Content is Available in the Text.

Food insecurity is associated with poor virologic outcomes, but this has not been studied during pregnancy and breastfeeding. We assessed sustained viral suppression from 8 weeks on antiretroviral therapy to 48 weeks postpartum among 171 pregnant and breastfeeding Ugandan women; 74.9% experienced food insufficiency. In multivariable analysis, food insufficiency [adjusted odds ratio (aOR) 0.38, 95% confidence interval (CI): 0.16 to 0.91], higher pretreatment HIV-1 RNA (aOR 0.55 per 10-fold increase, 95% CI: 0.37 to 0.82), and lopinavir/ritonavir versus efavirenz (aOR 0.49, 95% CI: 0.24 to 0.96) were associated with lower odds of sustained viral suppression. Interventions to address food security may improve virologic outcomes among HIV-infected women.

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.
