Experiences of Migrant People Living with HIV in a Multidisciplinary HIV Care Setting with Rapid B/F/TAF Initiation and Cost-Covered Treatment: The 'ASAP' Study.

This study aimed to explore the experiences of migrant people living with HIV (MLWH) enrolled in a Montreal-based multidisciplinary HIV care clinic with rapid antiretroviral treatment (ART) initiation and cost-covered ART. Between February 2020 and March 2022, 32 interviews were conducted with 16 MLWH at three time-points (16 after 1 week of ART initiation, 8 after 24 weeks, 8 after 48 weeks). Interviews were analyzed via the Framework Method. Thirty categories were identified, capturing experiences across the HIV care cascade. At diagnosis, most MLWH described "initially experiencing distress". At linkage, almost all MLWH discussed "navigating the health system with difficulty". At treatment initiation, almost all MLWH expressed "being satisfied with treatment", particularly due to a lack of side effects. Regarding care retention, all MLWH noted "facing psychosocial or health-related challenges beyond HIV". Regarding ART adherence, most MLWH expressed "being satisfied with treatment" with emphasis on their taking control of HIV. At viral suppression, MLWH mentioned "finding more peace of mind since becoming undetectable". Regarding their perceived health-related quality of life, most MLWH indicated "being helped by a supportive social network". Efficient, humanizing, and holistic approaches to care in a multidisciplinary setting, coupled with rapid and free ART initiation, seemed to help alleviate patients' concerns, address their bio-psycho-social challenges, encourage their initial and sustained engagement with HIV care and treatment, and ultimately contribute to positive experiences.

Barriers and facilitators related to HCV treatment uptake among HIV coinfected populations in Canada: Patient and treatment provider perceptions.

BACKGROUND: Direct-acting antiviral (DAA) uptake is challenging across HIV-hepatitis C (HCV) coinfected populations. This study sought to identify barriers and facilitators related to DAA uptake in priority populations in Canada. METHODS: This qualitative descriptive study included 11 people living with HIV with a history of HCV and 15 HCV care providers. Participants were part of either nominal groups (n = 4) or individual interviews (n = 6) in which they identified and ranked barriers and facilitators to DAA uptake. Consolidated lists of barriers and facilitators were identified thematically. RESULTS: Patient participants highly ranked the following barriers: competing priorities and needs (ie, social instability and mental health), delays in care, lack of adherence, and polypharmacy. Provider participant top barriers were the following: competing priorities and needs (ie, social chaos), delays in care (eg, systemic barriers, difficulties engaging patients, lack of trained HCV providers), and HCV-related stigma. Patient participants identified having a strong network of health care providers, family, and friends, possessing intrinsic motivation, and DAAs being a simple and tolerable oral treatment as important facilitators. Provider participant top-ranked facilitators were having resources to identify hard-to-reach populations (eg, patient navigation, outreach), holistic care and addiction management, provider HCV education, and a strong network of interprofessional collaboration. CONCLUSION: The barriers to DAA initiation addressed by patients and providers overlapped, with some nuances. Multidisciplinary care fostering a strong supportive network and intrinsically motivated patients along with HCV education emerged as key facilitators. This study provides insights for developing potential strategies to improve DAA uptake among HIV-HCV coinfected people in Canada.

Oral cannabinoids in people living with HIV on effective antiretroviral therapy: CTN PT028-study protocol for a pilot randomised trial to assess safety, tolerability and effect on immune activation.

INTRODUCTION: Despite antiretroviral therapy (ART), people living with HIV have higher rates of non-infectious chronic diseases. These conditions are driven by relatively high levels of inflammation persisting on ART compared with uninfected individuals. Chronic inflammation also contributes to HIV persistence during ART. Cannabis when taken orally may represent a way to reduce inflammation and strengthen immune responses. Before planning large interventional studies, it is important to ensure that cannabis taken orally is safe and well tolerated in people living with HIV. We propose to conduct a pilot randomised trial to examine the safety and tolerability of cannabis oils containing tetrahydrocannabinol (THC) and cannabidiol (CBD) consumed orally in people living with HIV. We will also measure inflammatory markers, markers of HIV persistence in peripheral blood cells and changes in the gastrointestinal microbiome. METHODS AND ANALYSIS: Twenty-six people living with HIV having undetectable viral load for at least 3 years will be randomised to receive TN-TC11LM (THC:CBD in 1:1 ratio) or TN-TC19LM (THC:CBD in 1:9 ratio) capsules daily for 12 weeks. Safety and tolerability of these capsules will be assessed through haematological, hepatic and renal blood tests, face-to-face interviews and questionnaires. Proportions of participants without any signs of significant toxicity (grades 0-2 scores on the WHO toxicity scale) and who complete the study, as well as scores on quality of life and mood will be examined using descriptive statistics. The effects on inflammatory markers, markers of peripheral blood reservoir size and effect on the composition of the gastrointestinal microbiome will be assessed before and after study completion. ETHICS AND DISSEMINATION: This study has been approved by the Research Institute of the McGill University Health Centre. A Data Safety Monitor will review safety information at regular intervals. The final manuscript will be submitted to an open-access journal within 6 months of study completion. TRIAL REGISTRATION NUMBER: NCT03550352.

The role of extended-release niacin on immune activation and neurocognition in HIV-infected patients treated with antiretroviral therapy - CTN PT006: study protocol for a randomized controlled trial.

BACKGROUND: Approximately 30% of HIV-1-infected patients receiving antiretroviral therapy who achieve virologic control have unsatisfactory immune reconstitution, with CD4+ T-cell counts persistently below 350 cells/µL. These patients are at elevated risk for clinical progression to AIDS and non-AIDS events. CD4+ T-cell depletion following infection and persistent immune activation can partially explain this low CD4+ T-cell recovery. Recent data suggest a link between the tryptophan oxidation pathway, immune activation and HIV disease progression based on overstimulation of the tryptophan oxidation pathway by HIV antigens and by interferon-gamma. This overstimulation reduces levels of circulating tryptophan, resulting in inflammation which has been implicated in the development of neurocognitive dysfunction. Niacin (vitamin B3) is able to control the excess tryptophan oxidation, correcting tryptophan depletion, and therefore represents an interesting strategy to improve CD4 recovery.We aim to design a crossover proof-of-concept study to assess supplementation with an extended-release form of niacin (Niaspan FCT™) in combination with antiretroviral therapy, compared to antiretroviral therapy alone, on T-cell immune activation as defined by changes in the percentage of CD8+ CD38+ HLA-DR+ T-cells. METHODS/DESIGN: This randomized, open-label, interventional crossover study with an immediate versus deferred use of Niaspan FCT for 24 weeks will assess its ability to reduce immune activation and thus increase CD4 recovery in 20 HIV-infected individuals with suboptimal immune responses despite sustained virologic suppression. A substudy evaluating neurocognitive function will also be conducted. DISCUSSION: This randomized trial will provide an opportunity to evaluate the potential benefit of oral extended-release niacin, a drug that can indirectly increase tryptophan, to reduce immune activation and in turn increase CD4+ T-cell recovery. The study will also allow for the evaluation of the impact of Niaspan FCT on neurocognitive function in HIV-infected individuals with suboptimal immune responses despite sustained virologic suppression. TRIAL REGISTRATION: This study was registered with ClinicalTrials.gov on 17 December 2013 (registration number: NCT02018965).
