Filter by:The mouth may play an important part in monitoring HIV progression. Mucosal lesions of the mouth are often the first sign of infection and their development in already diagnosed individuals indicates disease progression. In addition, saliva may provide a non-invasive way to track viral load. The purpose of this study is to establish standardized practices for examining the mouth and identifying oral mucosal lesions as well as to establish a correlation of viral load with HIV particles found in saliva.
INTRODUCTION: Studies prove that the pharmaceutical care (PC) increases the adherence to the antiretroviral; thus, they increase the undetectable viral load. The viral load diminishes, and the prevalence of undetectable viral load increases, as the levels of adherence to the treatment increase, being in general necessary high adhesion to reach the effectiveness therapeutic. Increasing the adherence levels, it increases the surviving chances and quality of life and diminishes the transmission risks. Studies demonstrate that the self-effectiveness expectation to use the medication correctly is the main predictor of adherence, and that the more complex the therapeutic regimen is, and the perception of side effects, the smaller the adherence is, highlighting the importance of preventing, identifying and solving the problems during the treatment with antiretroviral, problems related to the medication (PRM) through the PC. OBJECTIVES: To evaluate the effectiveness of the PC on the adherence of HIV-patients to the antiretroviral therapy, identify, prevent and solve PRMs during the treatment. METHODOLOGY: One-side randomized clinical trail controlled by non-intervention in parallel. 332 patients randomized are included in the control and intervention groups (PC). Questionnaires will be applied: sociodemographic, adherence to the antiretroviral through self-report, smoke, BECK (depression), CAGE (problems related with alcohol consumption) of self-effectiveness, expectation of results and social support. Each 4 months measure of viral load and CD4 will be carried out. The ones from the PC group will receive a card with information about the medication and all the medicines will be identified by different colors. The follow-up will last one year according to the instructions of DADER program.
This study plans to evaluate what happens to the brain in patients with HIV and early hepatitis C. The investigators will be comparing 3 groups of individuals: - Group 1: Individuals with HIV infection and acute (early) hepatitis C infection - Group 2: Individuals with HIV infection - Group 3: Healthy volunteers
Early identification of tuberculosis (TB) is of particular importance in HIV-infected individuals, as a delay of therapy can be devastating in those with compromised immune systems. Diagnosis of TB in HIV is difficult, however, because 24-61% of HIV co-infected individuals with pulmonary TB have negative TB test results. In addition, conventional testing can take 6 weeks or longer and may not be available at all in many settings. This study is being conducted to see whether some new tests for identifying TB and for identifying resistance to TB drugs are at least as accurate as the current testing methods when used on HIV-infected individuals. The study will also assess whether the new tests can provide accurate results faster than the current methods.
People with diabetes are at increased risk for atherosclerosis and have high CVD morbidity and mortality rates. Tools for detecting and quantifying atherosclerotic pro/regression in people with diabetes and other CVD risk factors lack sensitivity and specificity for molecular level events that occur during the early stages of atherogenesis. Inflammatory macrophage infiltration in the vessel endothelium is an early, molecular level proatherogenic event. Activated macrophages consume glucose at a high rate. Novel in vivo radiotracer PET/CT techniques have been developed to detect, image and quantify molecular level events like macrophage inflammation and glucose utilization (18FDG) in human vessels. We propose to develop and test this novel technique in the Center for Clinical Imaging Research (CCIR) at WUMS. We propose that HIV-infected people with significant CVD risk profiles are a suitable, unique human model for testing these novel imaging techniques. HIV-infected people taking anti-HIV medications develop insulin resistance, T2DM, dyslipidemia, central adiposity, and hypertension. HIV replicates in macrophages and represents a chronic proinflammatory condition. Recent data indicate that HIV+ CVD risk have greater risk for atherosclerosis and MI than HIV-negative people. To test feasibility, we hypothesize that: a.18FDG-PET/CT imaging will detect more macrophage glucose uptake and inflammation in the carotid and aorta arteries of HIV-infected people with CVD risk than in HIV-negative controls; b. radiotracer PET/CT measures of proatherogenic processes will correlate with carotid intima media thickness; a standard measure of carotid atherosclerotic burden. We propose to obtain pilot data that shows feasibility for a novel analytical approach that will expand capabilities for researchers interested in studying the links between diabetes, inflammation, and CVD in humans.
This study aims to verify the persistent control of the virus replication at 48 weeks after the simplification to tenofovir + emtricitabine + raltegravir or to lamivudine+abacavir+raltegravir in patients with optimal virological suppression without any virological failure to previous combined antiretroviral therapies needing a therapeutic switch for toxicity related issues or adverse events.
This study was a randomized strategy trial conducted among women who received highly active antiretroviral therapy (HAART) during pregnancy for purposes of prevention of mother-to-child transmission (PMTCT) of HIV but did not otherwise meet criteria to initiate HAART for their own health. The study was designed to determine whether continuation of HAART after delivery or other pregnancy outcome reduced morbidity and mortality compared to discontinuation and re-initiation of HAART when protocol specified criteria were met.
The purpose of the study is to determine the safety of mucosal immune responses to a DNA HIV vaccine followed by an adenoviral vector HIV vaccine in HIV uninfected adults.
The molecular mechanisms involved in squamous cell carcinoma of the anus (SCCA) are poorly elucidated. HIV-positive and renal transplant patients are at high risk for developing SCCA, indicating that immune suppression plays a facilitating role. The investigators previously demonstrated that chromosomal instability (CIN) was more prevalent in SCCA of HIV-negative than HIV-positive patients. Hence, the investigators postulate that microsatellite instability (MSI), another molecular pathway, might be a feature of SCCA progression in the HIV-positive population. Study Aims: 1. to determine the prevalence of MSI in paraffin-embedded tumor specimen of 15 patients from the Swiss HIV cohort who underwent surgical excision for SCCA; and 2. eventually, to test our hypothesis by assessing the MSI status of SCCA in 15 recently operated HIV-negative patients. Study Design: The study is designed in two steps: 1. Firstly, the investigators will retrieve tumor specimen from 15 HIV-positive patients, with a biopsy-confirmed diagnosis of SCCA, in three institutions. DNA from tumor and normal tissues will be extracted, and then amplified by PCR. Presence of MSI in tumors will be determined by assessing the microsatellite markers BAT25, BAT26, and CAT25. 2. Secondly, the results of molecular analysis will be compared with a population of HIV-negative patients, with the same tumors, using the same detection technique for MSI.
It has been estimated that black men who have sex with men (MSM) account for one quarter of all new HIV infections in the US annually, yet little prevention work has been directed towards this population. The purpose of this study is to research and potentially design a new and better way to try and slow the spread of HIV among black MSM.
