Filter by:Human Immunodeficiency Virus (HIV) infected patients in the Kaiser Permanente HIV registry wil be followed in the usual clinical care to estimate the rates of specified clinical events. The rates will be stratified by relevant characteristics like age, CD4 counts, HIV Viral Load (VL), HIV medication history. The rates in the HIV infected cohort wil be compared with the rates of these events in patients in the Kaiser Permanente database who are not infected with HIV.
Human Immunodeficiency Virus (HIV) infected patients who meet the entry criteria for the maraviroc pivotal trials (Maraviroc versus Optimized Therapy in Viremic Antiretroviral Treatment-Experienced Patients, MOTIVATE) will be identified from the EuroSIDA HIV cohort. The rates of specific clinical adverse events in this identified patient population will be compared with the rates of these events in the participants of the MOTIVATE trials.
The purpose of the study is to test the hypothesis that the addition of routine viral load testing to the standard laboratory monitoring of HIV patients on first-line antiretroviral treatment (ART) in Vietnam will result in better clinical outcomes for patients.
Methamphetamine (METH) is a debilitating and frequently abused substance that is often comorbid with HIV infection. HIV+ persons with current METH abuse or dependence (HIV+/METH+) have several characteristics, in addition to their substance use, that make them particularly susceptible to nonadherence to antiretroviral treatment (ART) including elevated rates of neurocognitive impairment, co-occurrence of psychiatric disorders, and unstable living situations. The investigators propose an intervention development study designed to address these potential mechanisms of nonadherence with the following Specific Aims: 1) To further develop and refine a personalized, automated, real-time, mobile phone, text messaging intervention (iTAB) designed to improve adherence to ART medications among HIV+/METH+ persons; 2) To evaluate the acceptability and effectiveness of a brief psychoeducation plus text messaging intervention (iTAB) as compared to psychoeducation alone (CTRL) for the improvement of objectively measured medication adherence among HIV+/METH+ persons; and 3) To examine predictors of within-person trajectories of nonadherence using the longitudinal data collected over the study. In order to realize these aims, the investigators will leverage the infrastructure of two unique UCSD resources increasing likelihood of study success, impact, and innovation: 1) the Translational Methamphetamine AIDS Research Center (TMARC), which is a NIDA-funded center that focuses on the combined effects of METH and HIV infection, and 2) the California Institute for Telecommunications and Information Technology (Calit2), which conducts research on state-of-the-art wireless means of health promotion. Initially, the investigators will refine the iTAB intervention to ensure that it is user-centered and tailored to the needs of HIV+/METH+ persons via focus groups and rapid prototyping. Once refined, the proposed iTAB intervention will use text messages that are automated, scalable, personalized, interactive, flexible, and motivating. The investigators will assess the acceptability and effectiveness of iTAB in improving objectively measured adherence (i.e., MEMS caps) over a 6-week period via a pilot RCT with 40 HIV+/METH+ assigned to the iTAB intervention and 20 HIV+/METH+ assigned to a psychoeducational control. Predictors of nonadherence including frequency of METH use, neuropsychological impairment, and mood will be examined to determine whether iTAB is better able to compensate for these factors associated with nonadherence as compared to CTRL. Further refinement to the iTAB intervention will be made in order to pursue a large-scale R01 using our tailored intervention.
In this project, we will work directly with underserved patients in a safety-net setting to conduct a randomized clinical trial of standard-of-care adherence counseling versus a novel adherence intervention embedded in an existing PHR that uses cellular phone short message service (SMS) reminders and patient responses to the reminders. We will compare adherence rates in both arms as assessed by antiretroviral medication concentrations in hair samples and self-report; clinical outcomes will also be compared in the two arms. The project will examine medication adherence for antiretroviral medications and treatments of common conditions such as depression, hypertension, diabetes and hypercholesterolemia.
Specific Aim: To conduct a randomized, placebo-controlled trial of extended release-naltrexone (XR-NTX) among Human Immunodeficiency Virus (HIV) infected prisoners meeting Diagnostic Statistical Manual IV (DSM-IV) criteria for opioid dependence who are transitioning from the structure of a correctional setting to the community. Hypotheses: i. XR-NTX will result in improved HIV clinical outcomes, including lower changes in HIV-1 RNA levels, higher CD4 counts and higher rates of retention in care. ii. XR-NTX will result in improved opioid treatment outcomes, including longer time to opioid relapse, lower addiction severity and lower craving for opioid. iii. XR-NTX will result in reduced drug- and sex-related HIV risk behaviors compared to the control group. iv. XR-NTX will result in decreased rates of reincarceration after 12 months of release to the community.
This Phase Ib pilot RCT will examine the safety, feasibility, and acceptability of a multi-component intervention to address traumatic stress symptoms among HIV-positive, methamphetamine-using men who have sex with men (MSM). Following a baseline assessment, 56 participants will be randomized to receive either: 1) a 7-session intervention to address traumatic stress related to living with HIV/AIDS; or 2) a 7-session, attention-control condition. Follow-up assessments will be administered at 1 and 3 months post-randomization.
This study is designed to determine whether administration of the GSK Biologicals HIV vaccine 732462 can lead to a reduction in viral load, and impact on the course of human immunodeficiency virus type 1 (HIV-1) infection. In HIV-1 infected persons who have not yet started antiretroviral therapy (ART), such a vaccine would potentially lead to a delay in the initiation of treatment.
HIV-infection is associated not only with a reduced function of the immune system, but also linked with diseases of other organ systems, in particular with the heart. Heart conditions that have been described with HIV include - Pericarditis, - Pleural effusion - Pulmonary hypertension (Venedic classification typ II) - Dilated cardiomyopathy - Heart failure - Myocarditis - Bacterial endocarditis - Heart valve disorders In addition to previously stated disorders of the heart, the premature atherosclerosis of coronary arteries, a further even more important disease of the heart in this patient population, went into the focus of most HIV-researchers and physicians. Premature atherosclerosis of coronary arteries results in coronary calcification, angina pectoris, myocardial infarction and sudden death. HIV-positive patients are at greater risk for a variety of heart-related conditions, including coronary artery disease. It is assumed, that HIV infection doubles the risk of a heart attack, according to recent research. The reason for this link between HIV and heart-related conditions is unknown, but secondary infections that affect the heart muscle and coronary arteries have a greater chance of occurring in people with compromised immune systems. In addition, the HI-virus itself had been detected in the myocardium and might have an impact on the premature of cardiovascular diseases. Furthermore, some of the medications used to treat HIV patients (antiretroviral therapy, ART) are assumed to have heart-related side effects. Therefore, current treatment regimens for HIV infection have to be balanced against the marked benefits of antiretroviral treatment. Nevertheless, prevention of coronary heart disease should be integrated into current treatment procedures of HIV-infected patients. The link between the heart and HIV is well established but not well understood. Therefore, further results are needed for efficient guidelines for the prevention, diagnostic and therapy of HIV-associated cardiovascular diseases.
The objective of this study is to determine efficacy of ritonavir-boosted lopinavir monotherapy as a maintenance regimen in HIV-1-infected patients who previously failed Non-nucleoside reverse transcriptase inhibitors (NNRTI) based regimens and currently received salvage protease-inhibitor (PI) based regimens.
