RESUMEN

Ending the HIV epidemic in the United States will require addressing social determinants contributing to poor care engagement among people living with HIV (PLH), such as food insecurity. Food insecurity is associated with poor care engagement among PLH. Yet, few studies have examined the perspectives of healthcare and social services providers on addressing food insecurity in HIV care. Guided by the Social Ecological Model, we conducted semi-structured interviews with 18 providers in New York State to understand barriers and facilitators to addressing food insecurity in HIV care. Thematic analysis illustrated eight themes across various levels of the Social Ecological Model. At the patient-level, providers perceived patients' feelings of embarrassment, shame, and judgement, and low health literacy as barriers. At the provider-level, challenges included limited time. Facilitators included fostering strong, patient-provider relationships. Barriers at the clinic-level included limited funding, while clinic resources served as facilitators. At the community-level, challenges included intersecting stigmas arising from community norms towards PLH and people who receive food assistance and limited access to healthy food. Findings suggest the need to incorporate their insights into the development of interventions that address food insecurity in HIV care.

RESUMEN

The COVID-19 pandemic was one of the deadliest global public health events. In the United States, over 1.1 million individuals have died, and now COVID-19 is the third leading cause of death (CDC, 2023). Vaccine uptake has stalled among different demographics. Vaccine hesitancy, a delay in accepting or refusing vaccines, poses a significant challenge regardless of the availability of safe and effective COVID-19 vaccines. This study aimed to identify disparate COVID-19 vaccine uptake among individuals in Western New York. The primary objective was to identify the factors contributing to lower rates of COVID-19 vaccination within this population.Data were collected from 585 adults recruited from 20 Niagara and Erie Counties sites using a self-administered survey on vaccine hesitancy, vaccination status, and COVID-19-related characteristics. The survey included the adult Vaccine Hesitancy Scale (aVHS) and acquired information on demographic characteristics and COVID-19 impact, knowledge, and information sources. Data were analyzed using descriptive statistics, a chi-squared test, a Wilcoxon rank-sum test, and a logistic regression model.Findings suggest that unvaccinated participants (n = 35) were concerned about vaccine side effects (48.6%). For vaccinated/unboosted participants (n = 52), they (40.0%) reported clinical concerns. After adjusting for gender and age, healthcare provider guidance and family guidance remained significant predictors of vaccination status, while clinical research studies were significant predictors of booster status. Findings from this study suggest public health interventions that target vaccine education and facilitate well-informed decisions about COVID-19 vaccines lead to less vaccine hesitancy.

RESUMEN

BACKGROUND: Neurocognitive impairment (NCI) in people with HIV (PWH) on antiretroviral therapy (ART) is common and may result from persistent HIV replication in the central nervous system. METHODS: A5324 was a randomized, double-blind, placebo-controlled, 96-week trial of ART intensification with dolutegravir (DTG) + MVC, DTG + Placebo, or Dual - Placebo in PWH with plasma HIV RNA <50 copies/mL on ART and NCI. The primary outcome was the change on the normalized total z score (ie, the mean of individual NC test z scores) at week 48. RESULTS: Of 357 screened, 191 enrolled: 71% male, 51% Black race, 22% Hispanic ethnicity; mean age 52 years; mean CD4+ T-cells 681 cells/µL. Most (65%) had symptomatic HIV-associated NC disorder. Study drug was discontinued due to an adverse event in 15 (8%) and did not differ between arms (P = .17). Total z score, depressive symptoms, and daily functioning improved over time in all arms with no significant differences between them at week 48 or later. Adjusting for age, sex, race, study site, efavirenz use, or baseline z score did not alter the results. Body mass index modestly increased over 96 weeks (mean increase 0.32 kg/m2, P = .006) and did not differ between arms (P > .10). CONCLUSIONS: This is the largest, randomized, placebo-controlled trial of ART intensification for NCI in PWH. The findings do not support empiric ART intensification as a treatment for NCI in PWH on suppressive ART. They also do not support that DTG adversely affects cognition, mood, or weight.

RESUMEN

Major depression is the most common neuropsychiatric disorder among people living with HIV (PLWH) and is predictive of high morbidity and mortality among them. This study estimated the prevalence and explored factors associated with depression among PLWH in two rural secondary health facilities providing anti-retroviral therapy (ART) services in Southwestern Nigeria between September and December 2020. The Patient Health Questionnaire-9 (PHQ-9) was used to screen and identify PLWH aged 18 years or older with depression. Descriptive statistics, bivariate and multivariate analyses were performed with SPSS version 23. A total of 172 respondents were screened. The prevalence of depression was 16.3% (95% CI 11.1%, 22.7%). Mild, moderate, and moderately severe depression was identified in 17 (9.9%), 8(4.7%) and 3(1.7%) of the participants, respectively. One (0.6%) respondent had suicidal ideation. Of PLWH with any depression, 20/28(71.4%) were within the 40-59 years of age range. None of the participants was on antidepressants. The factor most associated with depression was hypertension, with adjusted odd ratios of 9.8(95% CI 3.5-27.3, p < 0.0001). The study highlights the importance of screening for the severity of depression among PLWH in rural hospitals providing ART services in Africa. PLWH with comorbid hypertension were more likely to suffer from some form of depression.

RESUMEN

INTRODUCTION: Success with highly active antiretroviral therapy (ART) for the human immunodeficiency virus (HIV) in developing countries has been attributed to collaborative North-South resource-sharing and capacity-building. Academic research and training programmes have contributed towards policy entrepreneurship in a manner that influenced capacity-building within health systems. However, the documented capacity-building frameworks rarely elucidate how such programmes can be designed and implemented efficiently and sustainably. METHOD: We implemented the University of Zimbabwe (UZ)-State University of New York at Buffalo (UB) collaborative HIV clinical pharmacology capacity-building programme in Zimbabwe in 1998. We intuitively operationalized the programme around a mnemonic acronym, "RSTUVW", which spells out a supportive framework consisting of "room (space), skills, tools (equipment)", underpinned by a set of core values, "understanding, voice (clout) and will". Subsequent to our two decades of successful collaborative experience, we tested the general validity and applicability of the framework within a prospective programme aimed at expanding the role of health professionals. RESULTS AND CONCLUSION: Based on this collaborative North-South research and training capacity-building programme which has been positively validated in Zimbabwe, we propose this novel mnemonic acronym-based framework as an extra tool to guide sustainable capacity-building through collaborative North-South implementation research. Its extended use could also include assessment and evaluation of health systems within resource-constrained settings.

RESUMEN

BACKGROUND: Biological sex and the estrogen receptor alpha (ESR1) modulate human immunodeficiency virus (HIV) activity. Few women have enrolled in clinical trials of latency reversal agents (LRAs); their effectiveness in women is unknown. We hypothesized that ESR1 antagonism would augment induction of HIV expression by the LRA vorinostat. METHODS: AIDS Clinical Trials Group A5366 enrolled 31 virologically suppressed, postmenopausal women on antiretroviral therapy. Participants were randomized 2:1 to receive tamoxifen (arm A, TAMOX/VOR) or observation (arm B, VOR) for 5 weeks followed by 2 doses of vorinostat. Primary end points were safety and the difference between arms in HIV RNA induction after vorinostat. Secondary analyses included histone 4 acetylation, HIV DNA, and plasma viremia by single copy assay (SCA). RESULTS: No significant adverse events were attributed to study treatments. Tamoxifen did not enhance vorinostat-induced HIV transcription (between-arm ratio, 0.8; 95% confidence interval [CI], .2-2.4). Vorinostat-induced HIV transcription was higher in participants with increases in H4Ac (fold increase, 2.78; 95% CI, 1.34-5.79) vs those 9 who did not (fold increase, 1.04; 95% CI, .25-4.29). HIV DNA and SCA plasma viremia did not substantially change. CONCLUSIONS: Tamoxifen did not augment vorinostat-induced HIV RNA expression in postmenopausal women. The modest latency reversal activity of vorinostat, postmenopausal status, and low level of HIV RNA expression near the limits of quantification limited assessment of the impact of tamoxifen. This study is the first HIV cure trial done exclusively in women and establishes both the feasibility and necessity of investigating novel HIV cure strategies in women living with HIV. CLINICAL TRIALS REGISTRATION: NCT03382834.

RESUMEN

Support groups for people living with the Human Immunodeficiency Virus (HIV) have continued to evolve since their emergence over two decades ago. In addition to providing HIV education and fostering psychosocial support, recent efforts have shifted the focus to socio-economic activities and retention in care. The sense of urgency to adopt new treatment and prevention strategies in sub-Saharan Africa necessitates greater engagement of established HIV care programs, especially among researchers seeking to conduct implementation research, promote prevention strategies and optimize treatment as prevention. To maximize the utility of support groups in doing so, efforts to create an organized, collaborative framework should be considered. This paper aims to describe the process of refocusing an adult HIV peer-support group and illustrate how a structured program was strengthened to sustain implementation research in resource-limited settings, while promoting patient recruitment and retention. A multidisciplinary team of scientists supporting an HIV peer-support group spearheaded the implementation process that authored the successes, challenges and lessons documented over eight years. Psychosocial support, nutrition care and support, adherence education and income generating projects were the main interventions employed. The initiative resulted in seven peer-reviewed publications, submission of 23 scientific abstracts, scientific dissemination at 12 international conferences. Eleven research studies and 16 income generating projects were successfully conducted over eight years. More than 900 patients participated in peer-support group activities every month and 400 were engaged in income generating activities. This multidisciplinary structured program was valuable in the retention and recruitment of patients for implementation research and benefits extended to psychosocial support, microeconomic projects, and improved nutrition. The support group contributed to strengthening implementation research through providing a platform for identification of research priorities, patient recruitment and retention in studies and dissemination of research findings.

RESUMEN

While important advances have been made in the prevention and treatment of Human Immunodeficiency Virus (HIV) infection, limited expertise and resource constraints to effectively manage rollout of HIV programs often contribute to poor treatment outcomes in Sub-Saharan Africa. In 1998, the University of Zimbabwe (UZ) and the University at Buffalo, State University of New York (UB), developed a collaborative clinical pharmacology capacity building program in Zimbabwe to train the next generation of HIV researchers and support rollout of the national HIV program. The collaboration was funded by research and training grants that were competitively acquired through United States of America government funding mechanisms, between 1998 and 2016. Thirty-eight research fellows were trained and a specialty clinical pharmacology laboratory was established during this period. Knowledge and skills transfer were achieved through faculty and student exchange visits. Scientific dissemination output included sixty-two scholarly publications that influenced three national policies and provided development of guidelines for strategic leadership for an HIV infection-patient adherence support group. The clinical pharmacology capacity building program trained fellows that were subsequently incorporated into the national technical working group at the Ministry of Health and Child Care, who are responsible for optimizing HIV treatment guidelines in Zimbabwe. Despite serious economic challenges, consistent collaboration between UZ and UB strengthened UZ faculty scholarly capacity, retention of HIV clinical research workforce was achieved, and the program made additional contributions toward optimization of antiretroviral therapy in Zimbabwe.

RESUMEN

BACKGROUND: Direct-acting antivirals (DAAs) targeting hepatitis C virus (HCV) have revolutionized outcomes in human immunodeficiency virus (HIV) coinfection. METHODS: We examined early events in liver and plasma through A5335S, a substudy of trial A5329 (paritaprevir/ritonavir, ombitasvir, dasabuvir, with ribavirin) that enrolled chronic genotype 1a HCV-infected persons coinfected with suppressed HIV: 5 of 6 treatment-naive enrollees completed A5335S. RESULTS: Mean baseline plasma HCV ribonucleic acid (RNA) = 6.7 log10 IU/mL and changed by -4.1 log10 IU/mL by Day 7. In liver, laser capture microdissection was used to quantify HCV. At liver biopsy 1, mean %HCV-infected cells = 25.2% (95% confidence interval [CI], 7.4%-42.9%), correlating with plasma HCV RNA (Spearman rank correlation r = 0.9); at biopsy 2 (Day 7 in 4 of 5 participants), mean %HCV-infected cells = 1.0% (95% CI, 0.2%-1.7%) (P < .05 for change), and DAAs were detectable in liver. Plasma C-X-C motif chemokine 10 (CXCL10) concentrations changed by mean = -160 pg/mL per day at 24 hours, but no further after Day 4. CONCLUSIONS: We conclude that HCV infection is rapidly cleared from liver with DAA leaving <2% HCV-infected hepatocytes at Day 7. We extrapolate that HCV eradication could occur in these participants by 63 days, although immune activation might persist. Single-cell longitudinal estimates of HCV clearance from liver have never been reported previously and could be applied to estimating the minimum treatment duration required for HCV infection.

RESUMEN

BACKGROUND: Tenofovir alafenamide fumarate (TAF) co-formulated with elvitegravir (EVG; E), cobicistat (C), and emtricitabine (F), a recommended antiretroviral regimen, was evaluated for distribution and antiviral activity in cerebrospinal fluid (CSF) as well as neurocognitive (NC) performance change in participants switching from E/C/F/tenofovir disoproxil fumarate (TDF) to E/C/F/TAF. METHODS: This was a 24-week, single-arm, open-label study in treatment-experienced adults living with human immunodeficiency virus (HIV). Nine participants switched from E/C/F/TDF (150/150/200/300 mg once daily) to E/C/F/TAF (150/150/200/10 mg once daily) at week 12. CSF and total plasma concentrations of EVG, TDF, TAF, tenofovir (TFV), and HIV RNA levels were measured at baseline and week 24. NC performance was estimated by the Montreal Cognitive Assessment. RESULTS: EVG concentrations in CSF and the CSF:plasma ratio remained stable (P = .203) over time. Following the switch, TFV concentrations in CSF and plasma declined (P = .004), although the TFV CSF:plasma ratio increased (P = .004). At week 24, median TAF plasma concentration was 11.05 ng/mL (range, 2.84-147.1 ng/mL) 2 hours postdose but was below assay sensitivity 6 hours after dosing. TAF was below assay sensitivity in all CSF specimens. HIV RNA was ≤40 copies/mL in all CSF and plasma specimens. Three participants (33%) had NC impairment at baseline and 2 (22%) remained impaired at week 24. CONCLUSIONS: Switch to E/C/F/TAF was associated with reductions in TFV concentrations in CSF but stable EVG concentrations that exceeded the 50% inhibitory concentration for wild-type HIV, suggesting that EVG achieves therapeutic concentrations in the central nervous system. No virologic failure or significant NC changes were detected following the switch. CLINICAL TRIALS REGISTRATION: NCT02251236.
