Active clinical trials for "HIV Seropositivity"

Co-morbidities, including low bone mineral density, increased visceral adiposity and chronic kidney disease (CKD) are frequent in people living with HIV, and may be driven by ongoing inflammation and immune activation. Initiation of ART reduces inflammation and immune activation and is associated with changes in bone and renal biomarkers and gut microbiota. Investigators hypothesise that changes in gut microbiome when starting antiretroviral therapy correlate to changes in bone and renal biomarkers and wish to explore possible mechanisms linking these by investigating changes in markers of inflammation and immune activation.

Aim 1: Examine effects of algorithm-guided alcohol treatment on alcohol consumption and alcohol use Disorders (AUD) symptoms. Aim 2: Examine effects of algorithm-guided alcohol treatment on retention in HIV care and HIV-related outcomes. Aim 3: Examine effects of algorithm-guided alcohol treatment on comorbid conditions

Aim of the study is to evaluate the effects of a change in the intestinal microflora on the neuro-cognitive profile of patients with HIV infection receiving HAART treatment. Improvements will be evaluated with questionnaires on Quality of life and Cognitive and Behavior function. 20 patients will be enrolled and will receive 4 sachets of VSL#3 per day.

The purpose of this study is to test two study drugs, one of which is temazepam (15mg) and one of which is a placebo (an inactive substance that looks just like the temazepam), to see if insomnia (trouble sleeping) can be reduced in patients with HIV infection. Placebos are given in research studies to try and make sure that subjects are responding to the effects of the study drug and not to other factors, like the attention they are receiving. If you decide to take part in this study, you will take 1 capsule of study drug every night approximately 30 minutes before bedtime for approximately 12 weeks. This study is to test the study drug called temazepam for the treatment of insomnia (trouble sleeping) in patients with HIV infection. Temazepam has been approved by the FDA for the treatment of insomnia. However, because this study requires treatment for 12 weeks instead of the 7 to 10 days approved by the FDA, the use of temazepam is considered to be investigational in this study.

The primary objective of this pilot study is to evaluate the effect of the HPV vaccine Gardasil on anal condylomata recurrence and persistence rates in HIV positive patients.

The purpose of this study is to compare the effectiveness of two approaches to treating HIV-infected patients who are addicted to opioid drugs (e.g., heroin) in an inner-city HIV clinic. The two approaches are: Case management and referral - participants are managed by a case manager and referred to a specialized drug treatment center where they receive counseling and medications for opioid-dependence (e.g., methadone or buprenorphine); or Clinic-based treatment - participants receive counseling and treatment with buprenorphine at the HIV clinic.

Expected Enrollment: 40 patients Study Start Date: June 2005 Study Objectives: To conduct a pilot study to assess the safety, tolerability, and antiviral activity of Kaletra 400/100 mg taken twice a day (bid) in antiretroviral (ARV)-naïve HIV-infected patients at Week 48 Primary Objectives: To determine the proportion of patients with HIV RNA <400 copies/mL at weeks 24 and 48 To determine the proportion of patients with HIV RNA < 50 at weeks 24 and 48 To elucidate the specific adverse event (AE) profile of Kaletra single agent therapy Secondary Objectives: To assess the proportion of patients below the limit of quantification (LOQ) at each visit. Patients will be observed at baseline, weeks 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44 and 48. To determine the time to HIV RNA reaching <400 and <50 copies/mL To determine the time to virologic failure To assess change from baseline at each visit for HIV RNA and CD4 count at weeks 4, 8, 12, 24 and 48. To assess changes in genotype from baseline to time of confirmed virologic failure (2 consecutive HIV RNA measurements >400 copies/mL after suppressing to <400 copies/mL) or at time of treatment intensification. To characterize changes in lipid and triglyceride concentrations over time and the effect of treatment with appropriate drugs (fibrate or statin, if necessary) on these elevations. To evaluate the safety and tolerability of subjects through 48 weeks of drug exposure. To describe virologic response following intensification in Kaletra single agent virologic failures

To determine the MTD and dose-limiting toxicities of a regimen of therapeutic ganciclovir, antiretroviral therapy, and recombinant interleukin-2 (aldesleukin; Proleukin) as an immune adjuvant in HIV-seropositive patients. To investigate the effect of increasing doses of Proleukin on the time to progression of CMV retinitis in patients being treated with therapeutic ganciclovir and antiretroviral therapy. To evaluate the incidence and level of anti-IL-2 antibody formation to subcutaneously administered Proleukin in this patient population.

This study is designed as a randomized, open trial of intermittent continuous infusions of Interleukin-2 in HIV seropositive patients with a CD4 cell count between 200 and 500 cells/mm(3). The goal of the study is to determine the optimal duration of each infusion, and the optimal interval between infusions. Thirty-six patients will be randomized to 3 groups: Group A will be the control group with a regimen of five day infusions of IL-2 every eight weeks; Group B will receive IL-2 infusions every eight weeks, however the duration of each infusion will be determined by parameters reflecting T cell proliferation, with discontinuation of each infusion at a point when the response appears to be maximized; Group C will receive five day infusions of IL-2; however the interval between infusions will be determined by the response seen to the prior infusion, with the goal of administering infusions while the CD4 cell count remains above baseline from the prior infusion. The dose of interleukin-2 to be used will be 9 MIU by continuous infusion daily. All patients will be evaluated at the NIH at least every 4 weeks, and at that time safety labs and immune studies will be performed. In addition, patients in Groups B and C will undergo a laboratory evaluation weekly, at which time immune parameters, including CD4 number and percent, spontaneous blast transformation, soluble IL-2 receptor levels, and viral parameters, including branched DNA assay and p24 antigen, will be determined. The study duration will be approximately one year.

The study will evaluate the effect of implementing a family-centered care (FAM-CARE) program (where all HIV-positive family members are seen together as a unit and receive care together) on viral suppression and retention in HIV-positive children <15 years through enrollment of a prospective cohort of 660 HIV-positive children and their caregivers at sites that were randomized to either implement the family-care program (intervention sites) or continue the current standard of care (control sites).
