Filter by:Acquired Rifampicin Resistance has emerged as an important issue in the treatment of HIV-TB patients. It has not been a major problem in HIV-negative individuals treated for TB treated with standard intermittent regimens. The study would generate data on the efficacy of daily and thrice weekly regimen of ATT in pulmonary TB patients with HIV in the presence of highly active antiretroviral therapy (HAART). Not many trials have compared sputum conversion and adverse drug reaction between daily and intermittent regimens of ATT in HIV positive patients. This study provides a unique opportunity for comparison of daily and intermittent therapy for HIV patients with pulmonary TB looking into multiple dimensions of HIV-TB treatment namely efficacy, drug resistance, toxicity , drug interaction and immune reconstitution inflammatory syndrome. The primary outcome of the study is to compare the efficacy of three anti-TB regimens in a) reducing bacteriological failures and b) decreasing the emergence of Acquired Rifampicin Resistance (ARR). The secondary outcomes include unfavourable responses (clinical failures, deaths, relapses) as whole, treatment emergent adverse drug reactions, pharmacokinetic levels of ATT and incidence of immune reconstitution syndrome.
The Lung HIV goal is to facilitate the data and specimen collection efforts of eight individual HIV and pulmonary studies that operate under the direction of the NHLBI. The Lung HIV study will build on existing studies to facilitate the start-up of new projects to further the understanding of the relationship between pulmonary disease and HIV infection. There is only one clinical trial being performed in this network at Ohio State University and it will be reported here.
The population of HIV infected women seen at Boston Medical Center may have a higher frequency of anal cytologic and histologic abnormalities than what is reported for the non-HIV infected population.
The investigators hypothesize that following virological failure of a standard NNRTI+2N(T)RTI regimen second-line antiretroviral therapy consisting of ritonavir-boosted lopinavir and 2N(T)RTIs will offer comparable efficacy to that provided by ritonavir-boosted lopinavir and raltegravir. The study will be conducted for 96-weeks with the primary endpoint analyzed after 48-weeks. The primary endpoint is virological: a comparison of virological suppression in plasma < 200 copies/mL between the randomized arms after 48 weeks. Secondary and exploratory endpoints include virological, immunological, safety, clinical, metabolic, drug adherence, drug resistance and quality of life.
This study seeks to determine the most effective way to reach and provide pregnant women with accessible, comprehensive, and high quality HIV care and treatment.
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.
In this study, researchers from UCLA and Friends Community Center will work together in designing a program to assist young homeless stimulant-using gay and bisexual homeless men to complete the hepatitis vaccine and in reducing drug and sexual activity. Using nurse case management strategies, found successful with homeless adults as well as contingency management strategies, found successful with gay and bisexual homeless adults by the community partners, the investigators will evaluate the effectiveness of a program that combines both strategies. As stimulant use threatens to increase homeless persons' risk of exposure to hepatitis A and B viruses, particularly among young users who may not yet be HBV-infected, this research is targeted to engage this group in treatment, until they are suitably protected from HBV, and hopefully reduce risk for HCV and HIV as well.
One-hundred and fifty-nine school-age children with HIV in Kayunga District, Uganda were randomized to one of 3 treatment arms: 24 training sessions of a computerized cognitive rehabilitation therapy (CCRT) program called Captain's Log; 24 sessions of Captain's Log not titrated to child's performance; or no training intervention. Study Aim 1: To compare the neuropsychological benefit of 24 training sessions of Captain's Log CCRT to the active and passive control groups over a 8-week period, and at 3-month follow-up. Study Aim 2: To compare the psychiatric benefit of 24 training sessions of Captain's Log CCRT to the active and passive control groups over an 8-week period, and at 3-month follow-up. Study Aim 3: To evaluate how ART treatment status, and the corresponding clinical stability of the child modifies CCRT neuropsychological performance gains and psychiatric symptom reduction. Outcome Assessments: The Kaufman Assessment Battery for Children, 2nd ed. (KABC-2), Tests of Variables of Attention (TOVA) visual and auditory tests, CogState computerized neuropsychological screening test, Bruininks-Oseretsky Test of Motor Proficiency (BOT-2), and Achenbach Child Behavior Checklist (CBCL) will be administered before and after the 8-week training period and at 3-month follow-up post training. Captain's Log has an internal evaluator feature which will help us monitor the specific training tasks to which the children best respond. Analyses: We will compare neuropsychological and psychiatric gains over the 8-week training period and at 3-mo follow-up for our three study groups, anticipating that they will be significantly greater for the CCRT intervention children (Study Aims 1 & 2). These neuropsychological gains will be associated with improved school performance over the long-term. Intervention children clinically stable on ART will have greater gains than those not stable or virally suppressed on ART. Conclusion: CCRT will prove effective and sustainable for enhancing neurocognitive status in HIV children. Futher work will prove this approach viable for assessing and treating children in resource-poor settings.
HIV infection is associated with systemic inflammation that is involved in pathogenesis of atherosclerosis. Treatment of HIV infection may cause lipid profile disturbance and consequently, atherosclerosis progression. In general, extra virgin olive oil (EVOO) has beneficial effect on atherosclerosis markers. Our goals are to examine the effect of EVOO on atherosclerosis markers in HIV-treated patients. A controlled randomized cross-over study will be performed on 40 participants. They will consume EVOO and ROO (refined olive oil) during two 20 days intervention periods, interrupted with 14 days wash-out period. Before the trial and after both intervention periods we will analyze participants' blood for: ESR, white blood cell count, hsCRP, interleukin-6, oxidized LDL, glutathione peroxidase, superoxide dismutase, malondialdehyde, triglycerides, total cholesterol, HDL and LDL cholesterol, fibrinogen, factor VII and von Willebrand factor. We expect an improvement of these parameters after three weeks of EVOO consumption.
CCTG 590 is a open-label study to evaluate the impact of therapy intensification with Maraviroc (MVC) (a CCR5 inhibitor) to a stable suppressive HIV antiretroviral regimen on the rate of CD4+ T-cell recovery and gene expression profiles. Patients on a stable first-line HIV regimen with continued viral suppression and sub-optimal CD4+ T-cell counts will be eligible for this study. Those who are found to be eligible will have MVC (dose-adjusted to background HIV regimen) added to their current HIV regimen for 24 weeks. After the 24 week intensification, the MVC will be discontinued, the original antiretroviral regimen will be continued and the subjects will be followed for an additional 12 weeks. The investigators hypothesize that MVC will improve the rate of CD4 recovery. This improved CD4 recovery will be associated with favorable changes in gene expression profiles of genes involved with CD4 maintenance and circulation.
