Filter by:Background Recently, the CDC issued recommendations calling for HIV screening for patients aged 13-64, when the individual accesses the health care system. For many patients, the emergency department (ED) is the primary or only contact point for health care. The rapid HIV test can be done as a point of care test in the ED. Study Objectives A. Primary: 1. To initiate HIV testing in the Baystate ED. B. Secondary: 1. To estimate the resources involved in initiating a rapid HIV testing program in the ED. 2. To describe the process of initiating a rapid HIV testing program. 3. To compare the yield of testing for HIV in patients with known HIV risk factors compared to those without known risk factors. 4. To describe the characteristics of the population tested for HIV in the ED. 5. To determine the number of patients who declined testing and the reasons for declining testing. 6. To analyze ED staff attitudes re: HIV rapid testing in the ED. Methods A trained HIV Educator/counselor will approach patients in the ED to offer free rapid HIV testing, at a time they are not currently engaged with the health care provider. Study informed consent and HIV consent will be obtained prior to testing. The HIV educator will obtain demographic and clinical information on the enrolled subjects including prior HIV testing and HIV risk factors. Patients testing negative will be counseled regarding HIV risk reduction strategies. Patients with an initial positive rapid HIV test will have blood drawn for confirmation (Western Blot) and will be referred to an HIV clinic for follow-up and treatment. Additionally, to assess acceptability of rapid testing in the ED, a brief anonymous electronic survey will be conducted of health care providers in the ED prior to starting this pilot program and following the program. Data Analysis The yield of testing will be calculated as will the seroprevalence of those tested. Among patients who decline HIV testing but agree to study participation (sign consent form), the number refusing testing will be recorded and reasons for refusing will be analyzed. The yield of testing will be compared in patients with to those without known HIV risk factors.
This study is a pilot study examining the effect of extended-release niacin (Niaspan ®) on flow-mediated vasodilation (FMD) of the brachial artery, among human immunodeficiency virus (HIV)-1 infected individuals with low high density lipoprotein (HDL). Brachial artery diameter will be measured by high-resolution ultrasound at entry and week 12 of study. The primary comparisons will be change in FMD from baseline to 12 weeks within each of the two arms. The second specific aim will be to investigate the proportion of the effect of extended-release niacin on other known cardiovascular markers.
Genetic tests has been suggested to reduce side effects related to Nevirapine(NVP), a commonly prescribed component of highly active antiretroviral therapy(HAART) in developing countries. This clinical trials is designed to determine the efficacy and the cost-effectiveness of this approach in the developing countries setting. NVP-based HAART and efavirenz(EFV)-based HAART will be provided through Thai national universal health coverage. Information of the prescribed drug will be collected, and monitoring for the compliance with the prescribed highly active antiretroviral therapy will be conducted. Outcome measurements: The primary objective of this study is to evaluate the reduction in incidences of NVP associated cutaneous side effects by genotype based personalized prescription. The volunteers will be monitored for any solicited and non-solicited adverse effects for 6 months after drug administration, with first 6 weeks intensive monitoring for cutaneous adverse reactions. Laboratory safety profiles (Complete Blood Count(CBC), Alanine transaminase(ALT), Aspartate transaminase(AST), Blood Urea Nitrogen(BUN), creatinine, direct bilirubin, total bilirubin, lactate dehydrogenase, alkaline phosphatase) will be assessed during the intensive monitoring period (6 weeks). Statistical Methods: Descriptive statistics will be used to evaluate the conduct of the study. Analysis variables will include overall follow-up rate, drug compliance, and events of protocol violation. Laboratory and safety data will be presented using comparative statistics for each study group and compared within and between groups using standard parametric or non-parametric comparison tests, i.e., McNemar's test or paired t-test as appropriate. Comparison of rate of cutaneous adverse reaction, hepatitis and severe cutaneous adverse reaction(SCAR) will be made with chi-square test. Variable that shown significant different between the "standard of care" or control group and the "genetic test" or intervention group will adjusted for the final analysis with Poisson logistic regression. The overall rate of adverse events in all participants will be monitored whether the rate of adverse events is lower than the predefined criteria. The extension of trial may be considered based on the rate of adverse events.
The purpose of the study is to measure the pharmacokinetics (how a drug is absorbed, distributed and eliminated from the body) of lamivudine (3TC) and its active component after 3TC is given at two different doses, 300mg and 150mg once daily.
The purpose of this study is to assess the pharmacokinetics of plasma lopinavir/ritonavir over a 12-hour dosing interval, following administration to male and female HIV−negative healthy volunteers of: 1. Lopinavir/ritonavir 400/100 mg twice daily 2. Lopinavir/ritonavir 200/150 mg twice daily 3. Lopinavir/ritonavir 200/50 mg twice daily
To date, the majority of microbicide research has focused on the assessment of the safety and effectiveness of vaginal microbicides used for the prevention of HIV transmission via the vaginal compartment. Receptive anal intercourse (RAI) is common among men who have sex with men (MSM), and there is increasing evidence that heterosexual women in the developed and developing world also practice anal sex. It can, therefore, be anticipated that once vaginal microbicides are licensed, they will be used in both the vaginal and rectal compartments. As a consequence, there is a need to evaluate both the rectal and vaginal safety profile of candidate microbicides. Therefore, the primary objective of this study is to evaluate the systemic safety of 1% vaginally formulated tenofovir gel applied rectally. In addition, this study will evaluate the immunotoxicity of the gel and evaluate its acceptability; it will also use the oral tenofovir disoproxil fumarate tablets (TDF), rectally-applied tenofovir gel,and a placebo gel to compare their systemic and compartmental pharmacokinetic (pK) profiles. This study was designed to address the following hypotheses: - Vaginally-formulated tenofovir 1% topical gel when applied rectally will be safe using a combination of clinical and laboratory markers including assays specifically designed to measure mucosal toxicity - Tenofovir will be detectable at different concentrations in the various anatomic compartments sampled for pharmacokinetics following single and 7-day topical exposures - Exposure to tenofovir 1% gel will demonstrate prevention of ex vivo HIV-1 challenge using in vivo drug-exposed tissue as compared to baseline tissue samples - Orally delivered, single dose, 300 mg tenofovir disoproxil fumarate tablets will have similar safety profiles using routine blood safety indices as have been established in other trials and will show no mucosal safety concerns - The oral dose will have different multi-compartment concentration kinetics than the topical tenofovir and will also demonstrate preliminary (ex vivo) prevention using the explant infectivity assay - Vaginally formulated tenofovir 1% topical gel applied rectally will be acceptable to participants, as indicated by a score in the upper one third of the 10-point Likert scale on intentionality to use in the product in the future
The purpose of this study is to determine whether the combination of telaprevir, peginterferon alfa-2a, and ribavirin is safe and effective in treating hepatitis C virus (HCV) infection in subjects who are infected with both HCV and human immunodeficiency virus (HIV).
The purpose of this study is to describe the Central Nervous System exposure of maraviroc in HIV-1 infected subjects receiving a stable antiretroviral regimen, including maraviroc, at steady state.
Objectives: Safety and immunogenicity of MVA.HIVA vaccine in 20-week-old healthy Gambian infants born to HIV-1/2-uninfected mothers. Gross impact of MVA.HIVA on the immunogenicity of EPI vaccines (DTwPHib, HepB, PCV-7 and OPV) when administered at 20 weeks (4 weeks after the last EPI vaccines), who have had BCG vaccine within the first 4 weeks of life.
The purpose of this study is to look at levels of both a new anti-HIV drug called raltegravir and an existing anti-hepatitis C drug called ribavirin to see if they affect the blood levels of each other when given separately and together. This is a phase I, open-label, prospective, three phase, pharmacokinetic study.
