Filter by:The Principle objective of this study is To evaluate the performance of NRA, NRA-p and REMA-p for the detection of M. tuberculosis complex from sputum samples from adult pulmonary TB suspects in a high TB and HIV prevalence setting, using LJ and MGIT culture as gold standard. The Secondary objectives are: - To measure the performance of each assay (NRA, NRA-p, REMA-p) in sputum smear-negative patients - To describe the results of the colorimetric methods in HIV-positive and HIV-negative patients - To assess the time to detection of both NRA/NRA-p, REMA-p methods. - To evaluate the feasibility of the NRA, NRA-p, REMA-p methods. - To determine the rate of contamination of the NRA, NRA-p and REMA-p assays. - To evaluate the proportion and the clinical relevance of NTM among TB suspects in a high TB and HIV prevalence setting. - To provide capacity building for TB diagnosis in Mbarara.
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 this study is to evaluate the safety and reactogenicity of one booster dose of a HIV candidate vaccine after administration of one oral dose of chloroquine.
No randomized clinical trial to date has demonstrated a survival benefit of using regular HIV-1 ribonucleic acid (RNA) viral load (VL) testing to monitor patients' responses to antiretroviral therapy (ART) for HIV infection. The measurement of VL is recommended to monitor the response to ART in developed countries. In resource-constrained settings, the World Health Organization (WHO) does not recommend routine VL testing, in part due to the cost and complex infrastructure needed for reliable results. In these settings, WHO has proposed the use of clinical and CD4+ lymphocyte-based criteria to guide treatment decisions. However, multiple studies have demonstrated the poor performance of these criteria in sub-Saharan Africa and the frequent discordance between immunologic and virologic responses to ART. The use of routine viral load monitoring should be evaluated in resource-constrained settings. The investigators hypothesize that routine viral load testing of patients on ART will improve patient survival, decrease disease progression and development of drug resistance, and will be feasible and cost-effective for resource-constrained settings.
Patients will be followed every 6 months for a total of 5 visits (Month 0, 6, 12, 18 and 24). The first visit is the screening and entry visit which can occur at any time after the subject finishes SEARCH 001 study but preferably it should occur approximately 6 months after SEARCH 001 study completion. At each visit, patients will undergo the following 1. Assessment of function including activity of daily living questionnaire 2. History of medical illnesses, medication history 3. Neurological examination: All patients will have a neurological evaluation and neuropsychological evaluation to characterize neurocognitive and neurological status. (It is possible that patients within the non-dementia group will meet criteria for dementia after close testing is completed). 4. Neuropsychological assessment: 5. Thai Depression Inventory. 6. HIV viral load and storage of blood for proviral DNA level Final outcome assessment based on all available data. If possible, it is intended that these diagnoses will be determined through monthly VTC conference calls with UH investigators. This consensus conference will include the Thai investigators, the UH neurologist, the UH neuropsychologist and the UH principal investigators.
The objective of this study was to estimate the effects of a single dose of vardenafil on the blood pressure (BP) in subjects receiving maraviroc (MVC) (dosed to steady-state) and to assess the safety and tolerability of MVC in subjects receiving a single dose of vardenafil.
A clinical study to evaluate the use of cell phones to support drug adherence and follow-up of patients taking antiretroviral therapy (ART) for treatment of HIV. The intervention involves health-care providers sending regular short-message-service (SMS) text messages to patients and following up their responses. The hypothesis is that the cell phone intervention will improve ART adherence and health outcomes compared with the current standard of care.
The purpose of this study is to determine the effect of EFV (Efavirenz) and TDF (Tenofovir disoproxil fumarate) on the pharmacokinetics of TVR (Telaprevir) and to determine the effect of TVR on the pharmacokinetics of EFV and TDF. Pharmacokinetics means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body. Furthermore, the short-term safety and tolerability of giving TVR, EFV and TDF together will be evaluated.
This preliminary study will investigate the use of Acupuncture and Moxibustion (Acu/Moxa) for distal symmetric peripheral neuropathy (DSP) associated with HIV applying traditional Chinese medicine (TCM) evaluations conducted by a diagnostic acupuncturist. The investigators will evaluate the role of Acu/Moxa in reducing the symptoms of DSP related to HIV/AIDS and treatment side effects. The effects of symptom reduction on quality of life will also be examined. This application will establish a proof of principle for the role of Acu/Moxa in the treatment of DSP and provide data that will serve as a foundation for establishing a future larger clinical trial.
This pilot study will provide data on the safety and efficacy of the combination of Raltegravir (RAL) 400mg BID + Atazanavir (ATV) 300 mg BID in Antiretroviral (ARV)-experienced subjects that have a suppressed HIV viral load on a Ritonavir (RTV) boosted Protease Inhibitor (PI) based regimen who are then switched to a regimen of RAL 400mg BID +ATV 300mg BID.
