RESUMO

BACKGROUND: Persons with opioid use disorders who inject drugs (PWID) in the United States (US) face multiple and intertwining health risks. These include interference with consistent access, linkage, and retention to health care including medication for opioid use disorder (MOUD), HIV prevention using pre-exposure prophylaxis (PrEP), and testing and treatment for sexually transmitted infections (STIs). Most services, when available, including those that address substance misuse, HIV prevention, and STIs, are often provided in multiple locations that may be difficult to access, which further challenges sustained health for PWID. HPTN 094 (INTEGRA) is a study designed to test the efficacy of an integrated, "whole-person" strategy that provides integrated HIV prevention including antiretroviral therapy (ART), PrEP, MOUD, and STI testing and treatment from a mobile health delivery unit ("mobile unit") with peer navigation compared to peer navigation alone to access these services at brick and mortar locations. METHODS: HPTN 094 (INTEGRA) is a two-arm, randomized controlled trial in 5 US cities where approximately 400 PWID without HIV are assigned either to an experimental condition that delivers 26 weeks of "one-stop" integrated health services combined with peer navigation and delivered in a mobile unit or to an active control condition using peer navigation only for 26 weeks to the same set of services delivered in community settings. The primary outcomes include being alive and retained in MOUD and PrEP at 26 weeks post-randomization. Secondary outcomes measure the durability of intervention effects at 52 weeks following randomization. DISCUSSION: This trial responds to a need for evidence on using a "whole-person" strategy for delivering integrated HIV prevention and substance use treatment, while testing the use of a mobile unit that meets out-of-treatment PWID wherever they might be and links them to care systems and/or harm reduction services. Findings will be important in guiding policy for engaging PWID in HIV prevention or care, substance use treatment, and STI testing and treatment by addressing the intertwined epidemics of addiction and HIV among those who have many physical and geographic barriers to access care.

RESUMO

Despite high risk for serious non-AIDS events (SNAEs) and accelerated age-related increases in inflammatory markers relative to HIV+ men, HIV+ women have been understudied, particularly in terms of stress impacts on immune parameters. The purpose of this study was to examine sex differences in glucocorticoid-immune stress response in mid-life HIV+ individuals, as poor glucocorticoid control of stress-induced inflammation may contribute to health risk in HIV+ women. Male and female participants completed a threat of shock laboratory stressor. Serum cortisol and cytokines [interleukin (IL)-6, IL-8, IL-10, IL-1ß, C-reactive protein (CRP), tumor necrosis factor (TNF)-α, interferon (IFN)-γ] were assessed at six timepoints prior to and in response to the stressor. Participants included 8 HIV- controls (n = 5 female) and 9 HIV+ (n = 5 female) who were virally suppressed. Repeated measures mixed models revealed a significant sex by HIV status by time interaction for IL-10, IL-1ß, TNF-α, and cortisol. IL-10 response, an anti-inflammatory cytokine, was larger in males than females, regardless of HIV status. TNF-α response was blunted in HIV+ individuals compared with HIV-, and specifically in HIV+ women, IL-1ß and cortisol response were blunted. Individuals living with HIV may have impaired coordination between the immune system and hypothalamic pituitary adrenal (HPA) axis. HIV+ women in particular exhibited dysregulated IL-1ß and cortisol response to acute stress. Future work should focus on relationships among proinflammatory cytokines, stress, and SNAEs in HIV, with attention to sex as a biological variable.

RESUMO

INTRODUCTION: The need to integrate behavioral health care within medical settings is widely recognized, and integrative care approaches are associated with improved outcomes for a range of disorders. As substance use treatment integration efforts expand within primary care settings, training behavioral health providers in evidence-based brief treatment models that are cost-effective and easily fit within the medical flow is essential. METHODS: Guided by principles drawn from Diffusion of Innovations theory (Rogers, 2003) and the Consolidated Framework of Implementation Research (Damschroder et al., 2009), we adapted elements of Motivational Enhancement Therapy, cognitive-behavioral therapy, and 12-step facilitation into a brief counseling toolkit. The toolkit is a menu driven assortment of 35 separate structured clinical interventions that each include client takeaway resources to reinforce brief clinical contacts. We then implemented this toolkit in the context of a randomized clinical trial in three Federally Qualified Healthcare Centers. Behavioral Health Consultants (BHCs) used a pre-screening model wherein 10,935 patients received a brief initial screener, and 2011 received more in-depth substance use screening. Six hundred patients were assigned to either a single session brief intervention or an expanded brief treatment encompassing up to five additional sessions. We conducted structured interviews with patients, medical providers, and BHCs to obtain feedback on toolkit implementation. RESULTS: On average, patients assigned to brief treatment attended 3.29 sessions. Fifty eight percent of patients reported using most or all of the educational materials provided to them. Patients assigned to brief treatment reported that the BHC sessions were somewhat more helpful than did patients assigned to a single session brief intervention (p=.072). BHCs generally reported that the addition of the toolkit was helpful to their work in delivering screening and brief treatment. DISCUSSION: This work is significant because it provides support to clinicians in delivering evidence-based brief interventions and has been formatted into presentation styles that can be presented flexibly depending on patient need.

RESUMO

Stress is implicated in the pathogenesis and progression of HIV. The Transcendental Meditation (TM) is a behavioral stress reduction program that incorporates mind-body approach, and has demonstrated effectiveness in improving outcomes via stress reduction. We evaluated the feasibility of implementing TM and its effects on outcomes in persons with HIV. In this community-based single blinded Phase-I, randomized controlled trial, outcomes (psychological and physiological stress, immune activation, generic and HIV-specific health-related quality of life, depression and quality of well-being) were assessed at baseline and at six months, and were compared using parametric and nonparametric tests. Twenty-two persons with HIV were equally randomized to TM intervention or healthy eating (HE) education control group. Retention was 100% in TM group and 91% in HE control group. The TM group exhibited significant improvement in vitality. Significant between group differences were observed for generic and HIV-specific health-related quality of life. Small sample size may possibly limit the ability to observe significant differences in some outcomes. TM stress reduction intervention in community dwelling adults with HIV is viable and can enhance health-related quality of life. Further research with large sample and longer follow-up is needed to validate our results.

RESUMO

Acute and chronic alcohol abuse impairs various functions of the immune system and thus, has been implicated as a cofactor in the immunopathogenesis of human immunodeficiency virus (HIV) disease progression. We determined whether naltrexone, an opioid receptor antagonist widely used in the treatment of alcoholism, inhibits alcohol-mediated enhancement of HIV infection of T cells. Alcohol enhanced HIV infection of peripheral blood lymphocytes (PBL) and a human lymphoid cell line (CEMX174). Alcohol increased HIV X4 envelope (Env), not murine leukemia virus Env-pseudotyped infection of CEMX174 cells. Naltrexone antagonized the enhancing effect of alcohol on HIV infection of PBL and CEMX174 cells. The specific mu-opioid receptor antagonist, Cys2, Tyr3, Arg5, Pen7 (CTAP) amide, also blocked the enhancing effect of alcohol on HIV infection. Investigation of the underlying mechanism for the alcohol action showed that alcohol significantly increased endogenous beta-endorphin production and induced mu-opioid receptor mRNA expression in PBL and CEMX174 cells. The role of beta-endorphin in alcohol-mediated enhancement of HIV infection was indicated by the observations that naltrexone and CTAP antagonized ether alcohol- or exogenous beta-endorphin-mediated enhancement of HIV infection. These findings suggest a biological mechanism for the potential therapeutic benefit of naltrexone in treating HIV-infected alcoholics.
