Filter by:This is an investigator-initiated study to measure the impact of an educational intervention on the basic palliative approach for a multidisciplinary staff team at an outpatient HIV clinic. The study aims to: 1) refine a curriculum for non-palliative care clinicians caring for persons living with HIV disease early in the disease trajectory; 2) assess the impact of the palliative approach educational intervention on outcomes for 2 target populations: a) patients (mental health, quality of life, health-related quality of life and secondarily, retention in care and viral suppression) and b) staff (burn-out and caregiving stress). It is hypothesized that training outpatient HIV staff in palliative care competencies will improve care provided that might, in turn, improve clinical outcomes for HIV patients receiving care at that clinic. Quantitative data will be augmented by qualitative interviews of selected staff and patients at both clinics in the final year of the study to appreciate response to the intervention.
The purpose of this study is to test whether twice-daily Interactive Voice Response (IVR) calls made at the estimated times of patients' antiretroviral (ART) medication dosing and three reminder calls for monthly clinic appointments, will result in improvements in ART adherence, appointment attendance, health indicators (CD4 cell counts), coping skills, social support, depressive symptoms, and other quality-of-life indicators, compared to a control group receiving one IVR assessment call each week, over six months. This is a randomized controlled trial of the IVR intervention with n=400 PLH taking first line ART in India on a twice-a-day dosing schedule. The research is supported by an Indo-U.S. Bilateral review and funding collaboration between NIH and ICMR. The research is being implemented in Kolkata by Drs. Smarajit Jana (PI, India) and Protim Ray (Project Director) at Durbar, a community-based organization providing HIV/STD prevention and community development programs with sex workers and other at-risk communities. This is Phase 2 of a two-phase pilot project. Phase 1 was a one-month no-control pilot (n=46) for feasibility, acceptability, and patient feedback on preferences for messaging content. Phase 2 has two sites, described as Phases 2A and 2b, which will occur simultaneously and differ only in their recruitment sites and corresponding sampling strategy (sample size, gender ratio, eligibility criteria) based on site population characteristics. - Phase 2A will recruit n=80 women and n=20 men from Durbar's Mamata Care and Treatment Center (MCTC) (providing HIV testing and treatment linkage and support) and associated Mamata Network of Positive Women (MNPW), which focus on HIV+ sex workers and their male partners and networks. - Phase 2B will recruit n=100 women and n=200 men from the ART Centre at the Calcutta School of Tropical Medicine (STM), which hosts the largest ART center in the Northeast Region of India and has over 3,000 active patients on first line ART. The sampling plan reflects the gender distribution of clients and patients at the two sites. Participants will be randomized within each site and gender sub-sample to receive: - The IVR Intervention: consisting of two (2) automated voice calls ("intervention messages") each day for six months, PLUS one IVR assessment call (consisting of four [4] questions) every week for 6 months; OR, - The Control Condition: consisting of standard care, PLUS one IVR assessment call (consisting of four [4] questions) every week for 6 months. All participants will be interviewed in-person by a research team member at baseline and followed-up at 2- 4- and 6-months using structured questionnaires and recording information from the participant's personal medical record (i.e., their "ART Card") to assess background characteristics and intervention impacts on ART adherence, health quality-of-life (i.e., depressive symptoms, social support). All participants will receive one IVR assessment phone call (consisting of four (4) questions during each week of the 6 month study. Each once-a-week IVR assessment will ask about missed medication and the participant's health/quality of life, and participants will respond by keying in a 1 (yes) or 2 (no) on their mobile phone.
Cryptococcal meningitis is one of the most common central nervous system infections among HIV-infected patients. The outcome is generally severe. This study aims to determine long-term survival rate among HIV-infected CM patients in the era of antiretroviral therapy (ART). The secondary objectives are to clarify outcomes of CM and determine prognostic factors.
Introduction: Highly active antiretroviral therapy (HAART) has showed its effectiveness in the prevention of complications in seropositive for HIV patients. However, they develop some manifestations such as lipodystrophy, dyslipidemia, and glucose intolerance increasing cardiovascular risk. Clinical trials in general population and in patients on hemodialysis have demonstrated a significant reduction in cardiovascular events using fish oil. Omega-3 fatty acids are believed to be beneficial in prevention of atherosclerosis reducing lipids levels specially triglycerides. Also in general populations it has been described a benefit effect of omega 3 acids on oxidative stress. Objective: to know the effect of omega 3 acids on different markers of oxidative stress in seropositive HIV patients. Methods: We will perform a randomized parallel controlled clinical trial in seropositive HIV patients from 20 to 55 years old on clinical score A1, A2, B1 or B2 who received HAART. They will be randomly assigned to receive omega 3 fatty acids 2.4 g (Zonelabs, Marblehead MA) or placebo for 6 months. At baseline anthropometric measurements, lipid profile, glucose and stress oxidative levels (nitric oxide, malondialdehyde, total glutathion, and lipid peroxidation products) will be evaluated. Sample size was calculated according to different variables. We selected the biggest one calculated for a difference in nitric oxide of 25% after treatment between groups and a standard deviation (SD) value of 10µmol/L. Whit this information we obtained a sample size of 31 patients per group for an 80% statistical power with α= 0.05. Assuming a 15% patient lost, a sample size of 35 per group was considered.
The purpose of this study is to evaluate cumulative exposure to tenofovir diphosphate (TFV-DP) using dried blood spots (DBS) in treated HIV-infected patients who are receiving a TFV-based regimen. Using DBS will allow the investigators to assess this simple method to measure drug exposure in the clinical setting. The investigators hypothesize that TFV-DP levels will be lowest in individuals with a detectable viral load and highest in those with viral suppression.
Linking HIV-infected pregnant women into prevention of mother to child transmission (PMTCT) services and keeping them in care is important in ensuring that both mother and infant benefit from interventions that improve maternal health and decrease HIV transmission to infants. We propose an evaluation of strategies to link newly diagnosed HIV-infected women to care and keep them in care during pregnancy and after delivery in our study called MIR4HEALTH. The study will be conducted in Nyanza Province, Kenya. All participants will provide informed consent and will be randomized to receive the intervention, including individualized patient education, adherence support and phone call/Short Message Service (SMS) reminders for clinic appointments, or the standard of care (no additional intervention services).

In the era of HIV treatment as prevention (TasP), efforts are needed to identify evidence-based combination prevention approaches that achieve greater decreases HIV viral load among populations that are more likely to engage in HIV transmission risk behavior. Because methamphetamine-using men who have sex with men (MSM) are at greater risk for acquiring and transmitting HIV, interventions targeting stimulant use in this population of high-risk men could boost the effectiveness of TasP. At present, only conditional cash transfer approaches such as contingency management (CM) have demonstrated short- term efficacy in reducing stimulant use among substance-using MSM who are not actively seeking formal treatment. The proposed RCT will examine the efficacy of a positive affect intervention that is designed to optimize the effectiveness of CM to achieve long-term reductions in stimulant use and HIV viral load in this population. the team will examine the efficacy of this integrative intervention in a randomized controlled trial (RCT) with 110 HIV-positive, methamphetamine-using MSM. After enrolling in CM, participants will be randomized to receive either: 1) the positive affect intervention; or 2) a attention-matched control condition. Follow-up data will be collected at 3, 6, 12, and 15 months post-randomization. This RCT will provide an opportunity to examine the efficacy of an integrative intervention designed to promote long-term reductions in HIV viral load as the primary outcome. Secondary outcomes that will be examined include: increases positive affect, reductions in stimulant use, improvements in T-helper (CD4+) count, unsuppressed viral load, and decreases HIV transmission risk behavior. Identifying an efficacious intervention approach to decrease HIV viral load among methamphetamine-using MSM would substantially support the goals of the National HIV/AIDS Strategy to reduce HIV incidence and mitigate HIV-related health disparities.
The investigators seek to adapt, implement and evaluate a randomized controlled trial of an evidence based intervention delivered by Apache interventionists to reduce HIV/AIDS risk, targeting Apache adolescents. Specific study objectives include: 1. To perform formative research through focus groups and individual interviews on attitudes, practices and intervention preferences among Apache adolescents and community stakeholders. 2. To adapt the Focus on Youth (FOY) evidence-based intervention using findings from the formative research, components of Protection Motivation Theory, and input from a community advisory board. 3. To enroll 304 White Mountain Apache youth ages 13-19 to participate in a randomized intervention trial measuring behavior change at 6- and 12- months follow-up. 4. To determine the feasibility of gathering biological specimens via self-administered swabs to track sexually transmitted diseases among 18-19 year olds enrolled in this and future studies.
