Abstract
This study examined adherence to antiretroviral therapy (ART) among adolescents and young adults living with HIV in South Africa. Using survey data from 857 youth on ART, the study employed latent class analysis to identify subgroups based on self-reported reasons for missed ART doses. Three distinct classes emerged: the largest class (85%) occasionally forgot to take their medication or missed a dose because others were around, the second class (9%) missed doses only due to feeling sick, and the third class (6%) faced multiple barriers such as forgetting, feeling sick, worrying about side effects, or doubting the effectiveness of ART. Youth who reported multiple barriers to adherence had significantly lower adjusted odds (AOR = 0.35, 95% CI = 0.16-0.78) of reporting 90% past month adherence compared to those who occasionally forgot their medication. Additionally, contextual factors such as food security, being treated well at the clinic, and being accompanied to the clinic were associated with higher odds of adherence. The findings highlight the importance of considering co-occurring barriers to adherence and tailoring interventions accordingly. Addressing contextual factors, such as ensuring food security and providing supportive clinic environments, is also crucial for promoting optimal adherence among adolescents and young adults living with HIV.

Abstract
Background Studies which examine quality of life (QOL) provide important insights that are needed to understand the impacts of HIV/AIDS anti-retroviral treatment (ART), comorbid conditions and other factors on the daily activities of people living with HIV/AIDS (PLH). This study aimed to determine the inter-relationships between clinical factors, behavioural, socio-demographic variables and QOL among PLH. Methods The secondary analysis used data collected from 293 people living with HIV/AIDS (PLH) receiving second-line ART in Johannesburg in a clinical trial which evaluated the non-inferiority of ritonavir-boosted darunavir (DRV/r 400/100 mg) compared to ritonavir-boosted lopinavir (LPV/r) over a 48 week-period. Physical functioning, cognitive and mental QOL were measured using the Aids Clinical Trial Group questionnaire. Exploratory factor analyses were used to examine the structure, the relationships between and the construct validity of QOL items. Structural equation models which tested the a priori-hypothesised inter-relationships between QOL and other variables were estimated and goodness of fit of the models to the data was assessed. Results Patients on darunavir presented with lower pill burden. Older patients and women were more likely to report lower QOL scores. Pill burden mediated the effects of age, sex and treatment regimen on physical functioning QOL and adverse effects; the effects of age, sex, treatment regimen and adverse effects on cognitive QOL; and the effects of sex on mental QOL. Conclusion QOL among PLH is associated with socio-demographic and clinical factors. Therefore, QOL could be enhanced by considering PLH characteristics, clinical factors such as regimen side-effects profile, management of comorbid conditions and mitigating risks such as potential adverse drug-to-drug interactions among patients on ART.

Abstract
Latency reversing agents (LRAs), such as protein kinase C (PKC) agonists, constitute a promising strategy for exposing and eliminating the HIV-1 latent reservoir. PKC agonists activate NF-κB and induce deleterious pro-inflammatory cytokine production. Adjuvant pharmacological agents, such as ruxolitinib, a JAK inhibitor, have previously been combined with LRAs to reduce deleterious pro-inflammatory cytokine secretion without inhibiting HIV-1 reactivation in vitro. Histone deacetylase inhibitors (HDACi) are known to dampen pro-inflammatory cytokine secretion in the context of other diseases and synergize with LRAs to reactivate latent HIV-1. This study investigates whether a panel of epigenetic modifiers, including HDACi, could dampen PKC-induced pro-inflammatory cytokine secretion during latency reversal. We screened an epigenetic modifier library for compounds that reduced intracellular IL-6 production induced by the PKC agonist Ingenol-3,20-dibenzoate. We further tested the most promising epigenetic inhibitor class, HDACi, for their ability to reduce pro-inflammatory cytokines and reactivate latent HIV-1 ex vivo. We identified nine epigenetic modulators that reduced PKC-induced intracellular IL-6. In cells from aviremic individuals living with HIV-1, the HDAC1-3 inhibitor, suberohydroxamic acid (SBHA), reduced secretion of pro-inflammatory cytokines TNF-α, IL-5, IL-2r, and IL-17 but did not significantly reactivate latent HIV-1 when combined with Ingenol-3,20-dibenzoate. Combining SBHA and Ingenol-3,20-dibenzoate reduces deleterious cytokine production during latency reversal but does not induce significant viral reactivation in aviremic donor PBMCs. The ability of SBHA to reduce PKC-induced pro-inflammatory cytokines when combined with Ingenol-3,20-dibenzoate suggests SBHA can be used to reduced PKC induced pro-inflammatory cytokines but not to achieve latency reversal in the context of HIV-1.

Abstract
Optimal adherence to HIV antiretroviral therapy (ART) is challenging, and racial/ethnic disparities in adherence rates are substantial. The most common reason persons living with HIV (PLWH) give for missed ART doses is forgetting. We took a qualitative exploratory approach to describe, from the perspectives of African American/Black and Hispanic/Latino PLWH, what it means to forget to take ART and factors that influence forgetting. Participants (N = 18) were purposively sampled for maximum variability and engaged in semi-structured/in-depth interviews on HIV/ART management. The analysis took a directed content analysis approach. Participants were mostly male (56%) and African American/Black (79%), between 50 and 69 years old, and had lived with HIV for an average of 21 years. Findings were organised into six inter-related themes: (1) forgetting to take ART was a shorthand description of a complex phenomenon, but rarely a simple lapse of memory; (2) ‘forgetting’ was means of managing negative emotions associated with HIV; (3) life events triggered mental health distress/substance use which disrupted adherence; (4) historical traumatic events (including AZT monotherapy) and recent trauma/loss contributed to forgetting; (5) patient-provider interactions could support or impede adherence; and (6) intrinsic motivation was fundamental. Implications for HIV social service and health care settings are described.

Abstract
Depression worsens HIV outcomes in populations treated with antiretroviral therapy (ART) medications. Data are limited on the relationship between depression and HIV in untreated populations in sub-Saharan Africa. We aimed to identify associations between likely clinical depression, alcohol use, social support by partners, and HIV viral load (VL) among ART untreated women who recently became HIV positive and enrolled in the Microbicide Trials Network (MTN)-015 study. Analyses used cross-sectional data collected at baseline in MTN-015. Participants in this analysis (N = 190) enrolled from other MTN trials were not receiving ART and provided data on their HIV disclosure status to their husband or male partner and alcohol use behavior. The dependent variable, VL, was categorized as: low (≤400 RNA copies/mL; 9.1% of participants), medium (401-20,000 RNA copies/mL; 48.8%), and high (>20,000 RNA copies/mL; 42.0%). Depression was assessed using eight items from Hopkins Symptom Checklist; a cutoff of ≥1.75 indicated likely clinical depression. Independent variables with a significance of p ≤ 0.05 in unadjusted regressions were included in a regression adjusted for age, education, and time since seroconversion. Depressive symptoms were positively associated with high VL, in the adjusted regression (OR = 1.80; 95% CI = 1.07-3.01). Results suggest that likely having clinical depression may have a biological relationship with HIV disease progression.

Abstract
Introduction Few studies have estimated complete antiretroviral therapy (ART) adherence following HIV infection since the advent of the new ART guidelines in 2012. This study determined the prevalence and influence of sociodemographic, behavioral, and clinical factors on complete ART adherence among people living with HIV (PLWH) receiving medical care in Houston/Harris County, Texas. Methods Data from the Houston Medical Monitoring Project survey collected from 2009 to 2014 among 1073 participants were used in this study. The primary outcome evaluated was combined adherence, defined as complete, partial, and incomplete combined adherence based on three ART adherence types—dose, schedule, and instruction adherence. The duration living since initial HIV diagnosis was classified as <5, 5–10 and >10 years. Rao–Scott Chi-square test and multivariable proportional-odds cumulative logit regression models were employed to identify the sociodemographic, behavioral, and clinical characteristics of complete combined adherence among the three groups of PLWH living with HIV infection. Results More than one-half (54.4%) of PLWH had complete, 37.4% had partial, and 8.3% had incomplete combined adherence. Among these PLWH, 52.2% had been infected with HIV for >10 years, and 26.5% and 21.4% were infected for <5 years and 5–10 years, respectively. PLWH who were diagnosed <5 and 5–10 years were two times (aOR=1.71, 95% CI=1.13–2.57; aOR=1.69, 95% CI=1.10–2.59; respectively) more likely to experience complete combined adherence than those with >10 years of infection. Multiple sociodemographic, behavioral, and clinical characteristics were significantly associated with complete adherence and varied by the duration of HIV infection. Conclusion Measures of adherence should include all adherence types (dose, schedule, instruction), as utilizing a single adherence type will overestimate adherence level in PLWH receiving medical care. Intervention efforts to maintain adherence should target recently infected PLWH, while those aimed at improving adherence should focus on longer infected PLWH.

Abstract
INTRODUCTION Advances in HIV treatment have proven to be effective in increasing virological suppression, thereby decreasing morbidity, and increasing survival. Medication adherence is an important factor in reducing viral load among people living with HIV (PLWH) and in the elimination of transmission of HIV to uninfected partners. Achieving optimal medication adherence involves individuals taking their medications every day or as prescribed by their provider. However, not all PLWH in the USA are engaged in care, and only a minority have achieved suppressed viral load (viral load that is lower than the detectable limit of the assay). Sexual and gender minorities (SGM; those who do not identify as heterosexual or those who do not identify as the sex they were assigned at birth) represent a high-risk population for poor clinical outcomes and increased risk of HIV transmission, as they face barriers that can prevent optimal engagement in HIV care. Research in dyadic support, specifically within primary romantic partnerships, offers a promising avenue to improving engagement in care and treatment outcomes among SGM couples. Dyadic interventions, especially focused on primary romantic partnerships, have the potential to have a sustained impact after the structured intervention ends. METHODS AND ANALYSIS This paper describes the protocol for a randomised control trial of a theory-grounded, piloted intervention (DuoPACT) that cultivates and leverages the inherent sources of support within primary romantic relationships to improve engagement in HIV care and thus clinical outcomes among persons who are living with HIV and who identify as SGM (or their partners). Eligible participants must report being in a primary romantic relationship for at least 3 months, speak English, at least one partner must identify as a sexual or gender minority and at least one partner must be HIV+ with suboptimal engagement in HIV care, defined as less than excellent medication adherence, having not seen a provider in at least the past 8 months, having a detectable or unknown viral load or not currently on antiretroviral therapy. Eligible consenting couples are allocated equally to the two study arms: a structured six-session couples counselling intervention (DuoPACT) or a three-session individually-delivered HIV adherence counselling intervention (LifeSteps). The primary aim is to evaluate the efficacy of DuoPACT on virological suppression among HIV+ members of SGM couples with suboptimal engagement in care. The DuoPACT study began its target enrolment of 150 couples (300 individuals) in August 2017, and will continue to enrol until June 2021. ETHICS AND DISSEMINATION All procedures are approved by the Institutional Review Board at the University of California, San Francisco. Written informed consent is obtained from all participants at enrolment, and study progress is reviewed twice yearly by an external Safety Monitoring Committee. Dissemination activities will include formal publications and report back sessions with the community. TRIAL REGISTRATION NUMBER NCT02925949; Pre-results.

Abstract
For people living with HIV, lack of adherence to antiretroviral therapy (ART) is a serious problem and frequently results in HIV disease progression. Reasons for non-adherence include concomitant psychosocial health conditions – also known as syndemic conditions – such symptoms of depression or posttraumatic stress disorder (PTSD), past physical or sexual abuse, intimate partner violence (IPV), stimulant use, and binge drinking. The aim of this study was to investigate the association between syndemic conditions and medication adherence. The sample included 281 older men living with HIV who have sex with men (MSM). The study period was December 2012–July 2016. We observed the following syndemic conditions significantly decreased medication adherence: symptoms of depression (p = .008), PTSD (p = .002), and stimulant use (p < .0001). Past physical or sexual abuse, IPV, and binge drinking were not significantly associated with decreased medication adherence. The findings suggest that syndemic conditions may impact medication adherence in older MSM living with HIV.

Abstract
We reviewed the medical charts of 1,700 patients diagnosed with HIV who referred to a central HIV clinic in Tehran between 2004 and 2017. Participants who had a viral load of > 200 copies/mL after six months or more on antiretroviral therapy (ART) were grouped as virologic failure (VF). We assessed the demographic characteristics, diagnosis date, first ART regimen, and resistance to various ART drugs. Out of 1,700 patients, 72 (4.2%) had a treatment failure. Among those with treatment failure, 51.3% were on zidovudine + lamivudine + efavirenz, 13.9% were on tenofovir + lamivudine + lopinavir/ritonavir, and 12.5% were on tenofovir + emtricitabine + efavirenz. In patients with treatment failure, the highest resistance was to nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs) combination (44.4%). In these patients, resistance to tenofovir (one of the NRTIs) was 29.1%. The highest treatment failure was observed among patients treated with nevirapine (NVP) and efavirenz (EFV)-based regimen. Our findings suggest that protease inhibitors should be considered as first-line drugs in ART regimens in VF patients in Iran.

McMahon JM, Braksmajer A, Zhang C, Leblanc N, Chen M, Aidala A, Simmons J. Syndemic factors associated with adherence to antiretroviral therapy among HIV-positive adult heterosexual men. AIDS Res Ther 2019; 16:32. [PMID: 31706357 PMCID: PMC6842154 DOI: 10.1186/s12981-019-0248-9] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2019] [Accepted: 10/25/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Suboptimal adherence to HIV antiretroviral therapy (ART) and concomitant lack of viral control can have severe consequences for health and onward transmission among persons living with HIV. Little is known about the barriers and facilitators of optimal ART adherence among heterosexual HIV-positive men. METHODS Structural equation modeling (SEM) was performed to test a theory-derived model of ART adherence using data from a cross-sectional sample of 317 HIV-positive self-identified heterosexual men residing in New York City. We assessed a conceptual model in which mental health (depression, anxiety) and substance use dependence mediated the effects of socio-structural factors (HIV-related stigma, social support) on ART adherence, and subsequently, undetectable viral load. RESULTS Structural equation modeling analyses indicated that men who reported higher levels of HIV-related stigma tended to experience higher levels of general anxiety, which in turn was associated with reduced probability of optimal ART adherence. Moreover, men who reported higher levels of social support tended to exhibit less dependence on illicit substance use, which in turn was associated with increased probability of optimal ART adherence. African-American men reported lower ART adherence compared to other racial/ethnic groups. CONCLUSIONS Our findings support the hypothesis that substance use dependence and mental health problems, particularly anxiety, may be primary drivers of suboptimal ART adherence among heterosexual men, and that socio-structural factors such as HIV-related stigma and social support are potential modifiable antecedents of these drivers.

[PMID: 31647806 PMCID: PMC6812809 DOI: 10.1371/journal.pone.0219415] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Accepted: 10/10/2019] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Despite recent efforts to scale-up lifelong combination antiretroviral therapy (cART) in sub-Saharan Africa, high rates of unsuppressed viremia persist among cART users, and many countries in the region fall short of the UNAIDS 2020 target to have 90% virally suppressed. We sought to determine the factors associated with unsuppressed viremia (defined for the purpose of this study as >200 copies/ml) among sub-Saharan African women on lifelong cART. METHODS This cross-sectional analysis was based on baseline data of the PROMOTE longitudinal cohort study at 8 sites in Uganda, Malawi, Zimbabwe and South Africa. The study enrolled 1987 women living with HIV who initiated lifelong cART at least 1-5 years ago. Socio-demographic, clinical, and cART adherence data were collected. We used multivariable Poisson regression with robust variance to identify factors associated with unsuppressed viremia. RESULTS At enrolment, 1947/1987 (98%) women reported taking cART. Of these, HIV-1 remained detectable in 293/1934 (15%), while 216/1934 (11.2%) were considered unsuppressed (>200 copies/ml). The following factors were associated with an increased risk of unsuppressed viremia: not having household electricity (adjusted prevalence risk ratio (aPRR) 1.74, 95% confidence interval (CI) 1.28-2.36, p<0.001); not being married (aPRR 1.32, 95% CI 0.99-1.78, p = 0.061), self-reported missed cART doses (aPRR 1.63, 95% CI 1.24-2.13, p<0.001); recent hospitalization (aPRR 2.48, 95% CI 1.28-4.80, p = 0.007) and experiencing abnormal vaginal discharge in the last three months (aPRR 1.88; 95% CI 1.16-3.04, p = 0.010). Longer time on cART (aPRR 0.75, 95% CI 0.64-0.88, p<0.001) and being older (aPRR 0.77, 95% CI 0.76-0.88, p<0.001) were associated with reduced risk of unsuppressed viremia. CONCLUSION Socioeconomic barriers such as poverty, and individual barriers like not being married, young age, and self-reported missed doses are key predictors of unsuppressed viremia. Targeted interventions are needed to improve cART adherence among women living with HIV with this risk factor profile.

Patient Self-Reported Adherence to Ritonavir-Boosted Darunavir Combined With Either Raltegravir or Tenofovir Disoproxil Fumarate/Emtricitabine in the NEAT001/ANRS143 Trial. J Acquir Immune Defic Syndr 2019; 79:481-490.

Abstract
Supplemental Digital Content is Available in the Text. Background: The NEAT001/ANRS143 trial demonstrated noninferiority of ritonavir-boosted darunavir combined with either raltegravir (RAL + DRV/r) or tenofovir disoproxil fumarate/emtricitabine (TDF/FTC + DRV/r) in HIV-positive, antiretroviral-naive adults. In post hoc analyses, however, RAL + DRV/r showed inferiority in patients with baseline CD4+ <200/mm3 and HIV-1 RNA ≥100,000 copies per milliliter. This preplanned ancillary study was conducted to assess whether differences in adherence might explain efficacy results. Setting: Phase III, open-label, randomized, multicenter study in 15 European countries (ClinicalTrials.gov, NCT01066962). Methods: Seven hundred seventy-four participants self-reported adherence (modified AIDS Clinical Trials Group questionnaire) over 96 weeks [383 RAL + DRV/r (twice daily; 5 pills/day), 391 TDF/FTC + DRV/r (once daily; 4 pills/day)]. Primary endpoint was ≥95% versus <95% adherence to prescribed doses recorded (1) over the last 4 days or (2) on the visual analogue scale over the last 30 days. Results: Characteristics, except age, were similar between arms; 9% had CD4+ <200 cells/mm3 and HIV-1 RNA ≥100,000 copies per milliliter. Adherence ≥95% in the last 4 days (P = 0.029) or at the visual analogue scale (P = 0.0072) was higher with TDF/FTC + DRV/r than with RAL + DRV/r. Adherence ≥95% over the last 4 days was associated with lower probability of virological failure (P = 0.015). Adherence in patients with baseline CD4+ <200 cells/mm3 and HIV-1 RNA ≥100,000 copies per milliliter was similar to the rest of the population, and not significantly associated with efficacy measures, with no significant differences between arms. Conclusion: Adherence was high and slightly better in the TDF/FTC + DRV/r than in the RAL + DRV/r arm. No convincing evidence was found that higher failure rate in the RAL + DRV/r arm in the subgroup with worse baseline viroimmunological status is caused by adherence differences.

Use of the FITT framework to understand patients' experiences using a real-time medication monitoring pill bottle linked to a mobile-based HIV self-management app: A qualitative study. Int J Med Inform 2019; 131:103949. [PMID: 31561192 DOI: 10.1016/j.ijmedinf.2019.08.009] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2019] [Revised: 07/14/2019] [Accepted: 08/08/2019] [Indexed: 01/15/2023]
Abstract
OBJECTIVE The purpose of this work was to conduct an in-depth analysis to understand patients' experiences using a real-time medication monitoring pill bottle linked to an HIV self-management app. METHODS A descriptive qualitative study design was used. In-depth interviews were conducted using a semi-structured interview guide at the 3-month follow-up visit during a trial of the app for improving medication adherence which began in January 2018. Eligibility criteria were HIV-positive, over the age of 18, ownership of a smartphone, able to speak and understand English and self-report less than 80% adherence to medications in the past 30 days or a viral load of over 20 copies/mL (detectable). All interviews were audio-recorded and transcribed. Using thematic analysis, we explored emerging themes with similar patterns across interviews and organized the themes according to the constructs of the Fit between Individuals, Task and Technology (FITT) framework. RESULTS Thirty-eight persons living with HIV (PLWH), who were randomized to the intervention arm of the study trial, participated in the interviews. 79.0% of participants reported their race as African American/Black, 63.2% had completed some high school or less, and 79.0% reported an annual median income of less than $20,000. Data was collected until saturation was reached. A total of nine major themes organized by the FITT framework were identified. Three themes related to the fit between individuals and task were: motivation for strict medication adherence, self-efficacy for overall health management, and engagement with medication reminders. Four themes related to the fit between individual and technology were: ease of use, HIV-related stigma and disclosure of HIV status, customized alert of medication time windows based on individual routine set-up, and preference for device design. Two themes related to the fit between task and technology were: system functionality of data transfer from the electronic pill bottle to the app and self-awareness of system syncing signals. CONCLUSIONS This study demonstrated that tracking medication adherence and receiving push-notification medication reminders through the electronic pill bottle connected to the app encourages and supports PLWH in adhering to their medication regimens. Findings from this work highlight the importance of adequate consideration of the needs of intended users in designing customizable mobile health technology, including HIV-related stigma, disclosure of HIV status and antiretroviral therapy regimens.

[PMID: 30865051 PMCID: PMC6417801 DOI: 10.1097/qai.0000000000001965] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2018] [Accepted: 12/20/2018] [Indexed: 11/26/2022]
Abstract
BACKGROUND HPTN 067 assessed the feasibility of daily and non-daily dosing of open-label emtricitabine/tenofovir disoproxil fumarate (FTC/TDF)-based pre-exposure prophylaxis (PrEP). METHODS Factors associated with sex-related PrEP adherence were assessed among men who have sex with men (MSM) randomized to one of 3 PrEP dosing arms in HPTN 067 in New York City. Sex-related PrEP adherence was defined per protocol as at least 1 PrEP tablet taken within 4 days pre-sex and at least 1 additional PrEP tablet taken within 24 hours post-sex, assessed via electronic drug monitoring and weekly interviews. Demographic data and behavioral measures were evaluated for association with sex-related PrEP adherence. Logistic regression for clustered data was used to estimate the unadjusted and adjusted odds ratios. RESULTS Of 176 randomized MSM participants, 59% were Black, 10% White, 25% Hispanic, and 6% other; median age was 31 years. In the multivariable analyses, higher sex-related PrEP adherence was significantly associated with daily dosing arm, older age, employment, and higher PrEP adherence behavioral skills. Lower sex-related PrEP adherence was significantly associated with identifying as Black or Hispanic (compared with White), opiate use, and reporting "I forgot" as an adherence barrier. CONCLUSIONS This analysis identified populations of MSM who might benefit from additional support to optimize PrEP adherence, including those who are younger, unemployed, or opiate users. MSM with lower PrEP behavioral skills may benefit from targeted interventions. Further study is needed to assess racial and ethnic disparities in PrEP adherence, which may reflect broader social and economic inequalities not captured in this study.

Abstract
Relying on the most frequently reported barriers to adherence and convenient definitions of non-adherence may lead to less valid results. We used a dominance analysis (a regression-based approach) to identify the most important barriers to adherence based on effect size using data collected through an online survey. The survey included the Adherence Barrier Questionnaire, self-reported non-adherence defined as a 4-day treatment interruption, and HIV clinical outcomes. The sample (N = 1217) was largely male, gay identified, and White. Nearly 1 in 3 participants reported "simply forgot" as a barrier; however, in a dominance analysis, it yielded a small effect size it its association with a 4-day treatment interruption. Further, dominance analyses stratified by race/ethnicity and age suggested that not all barriers impact all groups equally. The most frequently reported barriers to adherence were not the most important, and interventions should focus on barriers more strongly linked to clinical outcomes.

Abstract
HIV-infected migrants were shown to have poorer treatment outcomes than Dutch HIV-infected patients, often due to worse treatment adherence. Self-reported adherence would be an easy way to monitor adherence, but its validity relative to pharmacy refill adherence has not been extensively evaluated in migrants. All HIV-infected migrants older than 18 years and in care at the two Rotterdam HIV-treatment centers were eligible. Refill data with leftover medication (PRL) (residual pill count) were obtained from their pharmacies up to 15 months prior to inclusion. Self-reported adherence to combination Antiretroviral Therapy was assessed by four questions about adherence at inclusion. Additionally, risk factors for pharmacy refill non-adherence were examined. In total, 299 HIV-infected migrants were included. Viral load (VL) was detectable in 11% of the patients. Specificity of PRL was 53% for patients with an adherence of 100% and decreased with lower cut-off values. Sensitivity and negative predictive value (NPV) were 68% and 15% and increased with lower cut-off values. Positive predictive value (PPV) was around 93% for all cut-off values. Using the self-reported questions, 139 patients (47%) reported to be adherent. Sensitivity was 49% and specificity was 72%. PPV and NPV were 95% and 13%. No risk factors for pharmacy refill non-adherence were found in multivariable analyses. Both PRL and self-reported adherence, can predict undetectable VL in HIV-infected migrants. PPV and NPV are similar for both methods. This study shows that using four self-reported items is sufficient to predict adherence which is crucial for optimal clinical outcome in HIV-infected migrants.

Abstract
BACKGROUND In light of recent changes to antiretroviral treatment (ART) guidelines of the World Health Organization and ongoing concerns about adherence with earlier initiation of ART, we conducted a systematic review of published literature to review the association between baseline (pre-ART initiation) CD4 count and ART adherence among adults enrolled in ART programs worldwide. METHODS We performed a systematic search of English language original studies published between January 1, 2004 and September 30, 2015 using Medline, Web of Science, LILACS, AIM, IMEMR, and WPIMR databases. We calculated the odds of being adherent at higher CD4 count compared with lower CD4 count according to study definitions and pooled data using random effects models. RESULTS Twenty-eight articles were included in the review and 18 in the meta-analysis. The odds of being adherent was marginally lower for patients in the higher CD4 count group (pooled odds ratio, 0.90; 95% confidence interval, 0.84 to 0.96); however, the majority of studies found no difference in the odds of adherence when comparing CD4 count strata. In analyses restricted to comparisons above and below a CD4 count of 500 cells per microliter, there was no difference in adherence (pooled odds ratio, 1.01; 95% confidence interval: 0.97 to 1.05). CONCLUSIONS This review was unable to find consistent evidence of differences in adherence according to baseline CD4 count. Although this is encouraging for the new recommendations to treat all HIV-positive individuals irrespective of CD4 count, there is a need for additional high-quality studies, particularly among adults initiating ART at higher CD4 cell counts.

Abstract
Medication adherence is the "Plus" in the global challenge to have 90% of HIV-infected individuals tested, 90% of those who are HIV positive treated, and 90% of those treated achieve an undetectable viral load. The latter indicates viral suppression, the goal for clinicians treating people living with HIV (PLWH). The comparative importance of different psychosocial scales in predicting the level of antiretroviral adherence, however, has been little studied. Using data from a cross-sectional study of medication adherence with an international convenience sample of 1811 PLWH, we categorized respondent medication adherence as None (0%), Low (1-60%), Moderate (61-94%), and High (95-100%) adherence based on self-report. The survey contained 13 psychosocial scales/indices, all of which were correlated with one another (p < 0.05 or less) and had differing degrees of association with the levels of adherence. Controlling for the influence of race, gender, education, and ability to pay for care, all scales/indices were associated with adherence, with the exception of Berger's perceived stigma scale. Using forward selection stepwise regression, we found that adherence self-efficacy, depression, stressful life events, and perceived stigma were significant predictors of medication adherence. Among the demographic variables entered into the model, nonwhite race was associated with double the odds of being in the None rather than in the High adherence category, suggesting these individuals may require additional support. In addition, asking about self-efficacy, depression, stigma, and stressful life events also will be beneficial in identifying patients requiring greater adherence support. This support is essential to medication adherence, the Plus to 90-90-90.

Abstract
INTRODUCTION HIV treatment guidelines recommend initiating antiretroviral therapy (ART) regardless of CD4 cell (CD4) count, barring contraindications or barriers to treatment. An estimated 6% of persons receiving HIV care in 2013 were not prescribed ART. We examined reasons for this gap in the care continuum. METHODS During 2013-2014, we surveyed a probability sample of HIV care providers, of whom 1234 returned surveys (64.0% adjusted response rate). We estimated percentages of providers who followed guidelines and their characteristics, and who deferred ART prescribing for any reason. RESULTS Barring contraindications, 71.2% of providers initiated ART regardless of CD4 count. Providers less likely to initiate had caseloads ≤20 vs. >200 patients [adjusted prevalence ratios (aPR) 0.69, 95% confidence interval (CI): 0.47 to 1.02, P = 0.03], practiced at non-Ryan White HIV/AIDS Program-funded facilities (aPR 0.85, 95% CI: 0.74 to 0.98, P = 0.02), or reported pharmaceutical assistance programs provided insufficient medication to meet patients' needs (aPR 0.79, 95% CI: 0.65 to 0.98, P = 0.02). In all, 17.0% never deferred prescribing ART, 69.6% deferred for 1%-10% of patients, and 13.3% deferred for >10%. Among providers who had deferred ART, 59.4% cited patient refusal as a reason in >50% of cases, 31.1% reported adherence concerns because of mental health disorders or substance abuse, and 21.4% reported adherence concerns because of social problems, eg, homelessness, as factors in >50% of cases when deferring ART. CONCLUSIONS An estimated 29% of HIV care providers had not adopted recommendations to initiate ART regardless of CD4 count, barring contraindications, or barriers to treatment. Low-volume providers and those at non-Ryan White HIV/AIDS Program-funded facilities were less likely to follow this guideline. Among all providers, leading reasons for deferring ART included patient refusal and adherence concerns.

Abstract
Following global efforts to increase antiretroviral therapy (ART) access in Sub-Saharan Africa, ART coverage among HIV-infected Cameroonians increased from 0% in 2003 to 22% in 2014. However, the success of current HIV treatment programs depends not only on access to ART, but also on retention in care and good treatment adherence. This is necessary to achieve viral suppression, prevent virologic failure, and reduce viral transmission and HIV/AIDS-related deaths. Previous studies in Cameroon showed poor adherence, treatment interruption, and loss to follow-up among HIV+ subjects on ART, but the factors that influence ART adherence are not well known. In the current cross-sectional study, patient/self-reported questionnaires and pharmacy medication refill data were used to quantify ART adherence and determine the factors associated with increased risk of non-adherence among HIV-infected Cameroonians. We demonstrated that drug side-effects, low CD4 cell counts and higher viral loads are associated with increased risk of non-adherence, and compared to females, males were more likely to forego ART because of side effects (p<0.05). Univariate logistic regression analysis demonstrated that subjects with opportunistic infections (on antibiotics) had 2.42-times higher odds of having been non-adherent (p<0.001). Multivariable analysis controlling for ART regimen, age, gender, and education showed that subjects with opportunistic infections had 3.1-times higher odds of having been non-adherent (p<0.0003), with significantly longer periods of non-adherence, compared to subjects without opportunistic infections (p = 0.02). We further showed that compared to younger subjects (≤40 years), older subjects (>40 years) were less likely to be non-adherent (p<0.01) and had shorter non-adherent periods (p<0.0001). The presence of depression symptoms correlated with non-adherence to ART during antibiotic treatment (r = 0.53, p = 0.04), and was associated with lower CD4 cell counts (p = 0.04) and longer non-adherent periods (p = 0.04). Change in ART regimen was significantly associated with increased likelihood of non-adherence and increased duration of the non-adherence period. Addressing these underlying risk factors could improve ART adherence, retention in care and treatment outcomes for HIV/AIDS patients in Cameroon.

Abstract
BACKGROUND Reasons for and frequency of nonadherence to antiretroviral therapy (ART) may have changed due to pharmacological improvements. In addition, the importance of known non-pharmacologic reasons for nonadherence is unclear. METHODS We performed a cross-sectional, noninterventional, multicenter study to identify current reasons for nonadherence. Patients were categorized by physicians into the following adherence groups: good, unstable, or poor adherence. Co-variables of interest included age, sex, time since HIV diagnosis, ART duration, current ART regimen, HIV transmission route, comorbidity, HIV-1 RNA viral load (VL), and CD4 cell count. Patients self-reported the number of missed doses and provided their specific reasons for nonadherent behavior. Statistical analyses were performed using Fisher's extended exact test, Kruskal-Wallis test, and logistic regression models. RESULTS Our study assessed 215 participants with good (n=162), unstable (n=36), and poor adherence (n=17). Compared to patients with good adherence, patients with unstable and poor adherence reported more often to have missed at least one dose during the last week (good 11% vs unstable 47% vs poor 63%, p<0.001). Physicians' adherence assessment was concordant with patients' self-reports of missed doses during the last week (no vs one or more) in 81% cases. Similarly, we found a strong association of physicians' assessment with viral suppression. Logistic regression analysis showed that "reduced adherence" - defined as unstable or poor - was significantly associated with patients <30 years old, intravenous drug use, history of acquired immune deficiency syndrome (AIDS), and psychiatric disorders (p<0.05). Univariate analyses showed that specific reasons, such as questioning the efficacy/dosing of ART, HIV stigma, interactive toxicity beliefs regarding alcohol and/or party drugs, and dissatisfaction with regimen complexity, correlated with unstable or poor adherence (p<0.05). CONCLUSION Identification of factors associated with poor adherence helps in identifying patients with a higher risk for nonadherence. Reasons for nonadherence should be directly addressed in every patient, because they are common and constitute possible adherence intervention points.

Abstract
Persons living with HIV (PLWH) in rural areas face different barriers to care and treatment adherence compared to persons in urban areas. Our project identified strategies used by a rural HIV clinic with high rates of viral suppression, as evidenced by data abstraction from medical records from January 2010 through December 2014, including 411 patients ages 18 years or older. As HIV viral load is used as a marker for adherence and impacts health outcomes and transmission, it is an important assay. The national goal is for 80% of PLWH to be virologically suppressed by the end of 2020. This clinic exceeded the goal in 2014 with observed rates of 80% to 90% suppression. Eleven national guidelines for HIV care have been adopted by this clinic, along with five additional evidence-based interventions. Nurses played a critical role in all of these methods, and our intent was to report success-related factors.

Abstract
Background Antiretroviral therapy (ART) treatment interruptions lead to poor clinical outcomes with unplanned or unstructured TIs (uTIs) likely to be underreported. This study describes; uTIs, their risk factors and association with survival. Methods Analysis of ART programmatic data from 11 countries across Asia and Africa between 2003 and 2013 where an uTI was defined as a ≥90-day patient initiated break from ART calculated from the last day the previous ART prescription would have run out until the date of the next ART prescription. Factors predicting uTI were assessed with a conditional risk-set multiple failure time-to-event model to account for repeated events per subject. Association between uTI and mortality was assessed using Cox proportional hazards, with a competing risks extension to test for the influence of lost to follow-up (LTFU). Results 40,632 patients were included from 11 countries across 33 sites (17 Africa, 16 Asia). Median duration of follow-up was 1.61 years (IQR 0.54–3.31 years), 3386 (8.3 %) patients died, and 3453 (8.5 %) were LTFU. There were 14,817 uTIs, with 10,162 (25 %) patients having more than one uTI. In the adjusted model males were at lower risk of uTI (aHR 0.94, p < 0.01, and age 20–59 was protective compared to <20 years (20–39 years aHR 0.87, p < 0.01; 40–59 years aHR 0.86, p < 0.01). Preserved immune function, as measured by higher CD4 cell count, was associated with a reduced rate of uTI compared to CD4 <200 cells/μL (CD4 200–350 cells/μL aHR 0.89, p < 0.01; CD4 >350 cells/μL aHR 0.87, p < 0.01), whereas advanced clinical disease was associated with increased uTI rate (WHO stage 3 aHR 1.10, p < 0.01; WHO stage 4 aHR 1.21, p < 0.01). There was no relationship between uTI and mortality after adjusting for disease status and considering LTFU as a competing risk. Conclusions uTIs were frequent in people in ART programs in low-middle income countries and associated with younger age, female gender and advanced HIV. uTI did not predict survival when loss to follow-up was considered a competing risk. Further evaluation of uTI predictors and interventions to reduce their occurrence is warranted.
