Filter by:Dyslipidemia is highly prevalent among patients with HIV infection and contributes to the increased cardiovascular disease risk in this patient population. Atorvastatin lowers plasma low-density lipoprotein (LDL) cholesterol levels and is used for prevention of artherosclerotic disease. Raltegravir, an HIV integrase inhibitor, could be one of the preferred antiretroviral agents in HIV patients with dyslipidemia because it has a beneficial lipid profile. Theoretically, no clinically relevant drug interaction is expected between atorvastatin and raltegravir. However, atorvastatin and raltegravir share similar metabolic pathways which could be relevant in the occurrence of pharmacokinetic interactions. In order to be able to recommend raltegravir and atorvastatin concomitant use, a pharmacokinetic study in healthy volunteers is proposed.
The main objective is to determine the feasibility of maintaining virologic suppression on standard plasma viral load by dose reduction of ATRIPLA ®.
The purpose of this study is to find out if starting anti-retroviral therapy (ART) above 500 cluster-of-differentiation-4 (CD4)+ cells/milliliter (mL) ('early ART group') is better at reducing the stiffness of arteries than waiting to start ART until the CD4+ drops below 350 cells/mL ('deferred ART group'). Artery stiffness has been associated with an increased risk of cardiovascular (heart) disease, and could be useful as an earlier indicator of heart disease. In this study, the stiffness of arteries will be measured at study entry, months 4, 8, 12, and annually thereafter, using a tonometer on the participant's forearm.
Our goal is to advance palliative care with persons living with AIDS (PLWA) or life-limiting co-morbidities to decrease suffering and increase quality of life (QOL). Left without advance care planning (ACP) for end-of-life decision, miscommunication and disagreements may result in families being charged with neglect or court battles over treatment choices, unmet care or delivery of unnecessary or unwanted care, and non-relative caregivers being dismissed (e.g. gay partners). We hope to increase families' understandings of their family member's wishes for end-of-life care to decrease conflict through the FAmily-CEntered Advance (FACE) Care Planning intervention. We will also study communication, quality of life, and spiritual struggle. Families will be randomized into either the Control (N=96 families) or the FACE Intervention (n=192 dyads). FACE families will meet with a trained/certified researcher for two 60-minute sessions scheduled one week apart: Session 1: The Respecting Choices Interview®; and Session 2: Completion of The Five Wishes©. Control families will also meet with a researcher for two 60-minute sessions scheduled one week apart: Session 1: Developmental History; and Session 2: Nutrition and Exercise. Questionnaires will be administered five times, Baseline and at 3, 6, 12 and 18 month post-intervention, for an average of 2 years. AIM 1. To determine the efficacy of FACE on congruence in treatment preferences between PLWA and their surrogates over time, and the effect of the pattern of congruence development trajectory on healthcare utilization (i.e., distal outcomes: number of hospitalizations, dialysis, ER visits). Hypothesis A: Development of congruence may not be homogeneous and FACE may influence the pattern of congruence development. Hypothesis B: Different patterns of congruence development may have different effects on health care utilization. Hypothesis C: Compared to Controls, FACE participants will better maintain congruence over time. AIM 2. To determine the efficacy of FACE on key components of QOL for PLWA. Hypothesis: FACE participants will increase or better maintain psychosocial QOL compared to Controls. AIM 3. To minimize health disparities in ACP between Blacks and non Blacks and identify factors associated with disparities. Hypothesis: Blacks in the FACE intervention will complete advance directives at a rate comparable to non Blacks, and at significantly greater rates compared to Controls.
Men who have sex with men (MSM) continue to be the most heavily-impacted risk group in the US HIV epidemic. Studies suggest that the majority of incident HIV infections among MSM are attributable to sex with a main male sex partner. However, HIV prevention interventions that target male-male couples are lacking. Because of this, Couples HIV Voluntary Counseling and Testing (CVCT), an intervention that has been repeatedly shown to reduce HIV transmission within heterosexual couples, has been adapted to US MSM couples. Additionally, novel evidence demonstrates that antiretroviral therapy (ART) not only reduces morbidity and mortality among HIV-positive persons, but also serves to reduce the risk of HIV transmission to a negative partner by 96%. As adherence to ART is modifiable and levels of peer support have been shown to increase ART adherence, this current study proposes to use CVCT combined with dyadic adherence counseling ("CVCTPlus") to improve linkage to care, retention in care, ART adherence, and viral suppression among male-male couples using a cohort of 350 serodiscordant (one HIV(+) partner, one HIV(-) partner) couples in the greater Atlanta, Chicago, and Boston areas. Prospective couples (175 in each arm) will be followed for 18 months. At each visit, they will receive HIV testing, and both partners will complete a study survey measuring social and behavioral factors that may influence adherence, such as a couple's coping ability and their concordance of agreements regarding outside sex partners. Additionally, couples in the intervention arm will receive two additional sessions of Partner-STEPS.
This exploratory study aims to design and test an HIV prevention intervention for young men who have sex with men (MSM) between the ages of 16-20 as this group comprises the US adolescent population most at-risk for HIV infection through sexual contact. To help develop the content and format of our intervention we will first conduct in-depth interviews with twenty-one 18 to 24 year-old young MSM who acquired HIV through male-to-male sexual contact between ages 16-20 (i.e., the target age of our intended intervention). We will then design a group-based primary intervention for young MSM between ages 16-20, relying on the information we gathered from these interviews, as well as consultation from an advisory board of young MSM and HIV prevention experts. Last, we will use an experimental design to compare our intervention to a control condition. We hypothesize that, relative to a control condition of sexual health education and risk reduction, participants in our intervention will demonstrate lower rates of HIV risk behavior, find participation more feasible, and endorse greater acceptability of our intervention.
Tropical fevers have been a diagnostic challenge from the antiquity. Nowadays, despite the availability of good diagnostic capacities, undifferentiated febrile illnesses continue to be a thorny problem for travel physicians. In developing countries, the scarcity of skilled personnel and adequate laboratory facilities makes the differential diagnosis of fevers even more complex. Health care workers must often rely on syndrome-oriented empirical approaches to treatment and might overestimate or underestimate the likelihood of certain diseases. For instance Neglected Tropical Diseases (NTD) contribute substantially to the burden of persistent (more than 1 week) fevers in the Tropics, causing considerable mortality and major disability. These diseases are however rarely diagnosed at primary health care (PHC) level. The difficulty in establishing the cause of febrile illnesses has resulted in omission or delays in treatment, irrational prescriptions with polytherapy, increasing cost and development of drug resistance. In resource-limited settings, clinical algorithms constitute a valuable aid to health workers, as they facilitate the therapeutic decision in the absence of good laboratory capacities. There is a critical lack of appropriate diagnostic tools to guide treatment of NTDs. While clinical algorithms have been developed for some NTDs, in most cases they remain empirical. Besides, they rarely take into account local prevalence data, do not adequately represent the spectrum of patients and differential diagnosis at the primary care level and often have not been properly validated. The purpose of the study is to develop evidence-based Rapid Diagnostic Test (RDT)-supported diagnostic guidelines for patients with persistent fever (≥ 1 week) in the Democratic Republic of the Congo (DRC), Sudan, Cambodia and Nepal.
The main aims of this study are to determine whether: a) ART-naïve HIV+ subjects have increased artherosclerotic plaque inflammation/vulnerability, b) newly-initiated QUAD/Stribild therapy will decrease plaque inflammation/vulnerability in these subjects, and c) QUAD/Stribild therapy will improve indices of immune dysregulation and lipid dysfunction as a mechanism of improved plaque inflammation/vulnerability. Parameters of lipid and immune function will also be assessed in healthy control subjects, for comparison.
Kaposi sarcoma (KS) is an AIDS-related cancer and is the most commonly reported cancer in Zimbabwe. If it is found early on, it may be treatable with antiretroviral therapy (ARVs) alone and this will improve general well-being and ease of care. It may also be possible to avoid use of expensive chemotherapy if the KS is picked up early on in the course of the disease. Early KS is often overlooked or not recognized by health professionals. The purpose of the study is to learn more about if the level of medical care and treatment provided at primary care clinics in Zimbabwe will help people with AIDS-KS do better and maintain their health longer. This will be done by monitoring how KS is diagnosed and treated at the primary care clinics. Clinics will then have training in how to recognize and treat KS so that they can better identify and care for patients with the disease.
The purpose of this study is to evaluate the effectiveness of reducing HIV transmission among sero-discordant couples by applying comprehensive intervention components.
