Active clinical trials for "Acquired Immunodeficiency Syndrome"

The average period of asymptomatic HIV-infection is 8 years, at this stage, CD4+ T lymphocyte count was reduced gradually at the rate of 50~100cells/ul/year. When the CD4 T lymphocyte count dropped below 350cells/ul and viral load increased to 105 in AIDS patients, HAART will be carried out. But, CD4 T lymphocyte was 350~550 cells/ul, there is no intervention measures.

The purpose of this study is to examine the effect of GB virus C (GBV-C) on the natural history of chronic hepatitis C virus (HCV) infection in subjects co-infected with HIV and HCV. The other aspect of the study is to assess the effect of GBV-C on the severity of liver disease due to chronic hepatitis C in subjects co-infected with HIV and HCV. This will be done by determining the point prevalence of co-infection retrospectively then following that cohort prospectively. In addition, further individuals will be recruited in a prospective manner.

Poor compliance is thought to be a major cause of treatment failure. The TEddI study is a randomised, multi-centre, open-label study in well-controlled treatment-experienced HIV-infected patients to assess compliance with a once-daily regimen of antiretroviral therapy versus continuation of current anti-retroviral regimen delivered at least twice daily.

The study aims to evaluate the virological effectiveness of a third-line regimen combining dolutegravir (DTG), ritonavir-boosted darunavir (DRV/r) and optimized NRTI in Cambodian HIV-infected adults, who failed a protease inhibitors (PI)-based second-line regimen despite 3 months of boosted adherence counseling (BAC).

This is an extension study, to provide continued access to PRO 140 to subjects who complete participation in PRO140_CD02 and continue to receive clinical benefit and would require PRO 140 to form a viable regimen, in the opinion of the treating physician. The patient population for this trial are treatment-experienced HIV infected patients with CCR5-tropic virus who demonstrate evidence of HIV-1 suppression after successfully completed 24 weeks of treatment in the PRO140_CD02 study.

Although tuberculosis is a treatable disease, it is currently the infectious disease with the highest mortality in the world. It is estimated that one-third of the world's population is infected. HIV is the main predisposing factor for TB development. The Brazilian Ministry of Health and the World Health Organization recommends that patients should initially be treated orally with RIPE - rifampicin (R), isoniazid (I), pyrazinamide (P) and ethambutol (E). The N-acetylcysteine (NAC) first benefit was reported during the 1960s, when it proved to be an effective mucolytic agent in individuals with cystic fibrosis. Later, a new role arose when investigating its therapeutic potential in acetaminophen intoxication. Cleavage of the acetyl group makes cysteine available for later incorporation into glutathione synthesis, decreased in hepatic injury caused by acetaminophen. This mechanism causes NAC to have an indirect antioxidant effect, which aroused an interest in studying the effect in diseases that occur with oxidative stress. TB and HIV/Aids are also diseases with chronic inflammation. The present study aims to evaluate the effects of NAC as a adjuvant therapy in the treatment of TB. This is a phase II randomized clinical trial in which the safety and tolerability of NAC as adjunctive therapy for TB treatment will be assessed. Fifty-six patients will be randomized into two groups. The first group will receive the standard tuberculosis treatment as recommended by the Brazilian Ministry of Health (RIPE); the second will receive in addition to this treatment 1200mg of NAC per day for two months. In this way, microscopy and culture conversion rate to mycobacteria at 8 weeks, levels of glutathione and biomarkers of immune activation and inflammation in case of TB with or without NAC will be monitored.

The purpose of this study is to assess the tolerability, adherence and efficacy of single tablet dolutegravir/abacavir/lamivudine antiretroviral therapy in people living with HIV with a history of injection drug use (IDU) switching from existing antiretroviral therapy (ART) or starting treatment after discontinuation of ART.

The purpose of this study is to assess the efficacy and tolerability of orally administered dimiracetam for 10 weeks to AIDS patients under treatment with antiretroviral agents presenting a disease and /or treatment related neuropathic pain.

The purpose of this study is to determine if treatment with pegylated interferon alpha 2b (peg-IFN-α2b) will reduce the amount of integrated HIV DNA in peripheral blood cells and tissues of individuals with chronic HIV infection receiving antiretroviral treatment (ART). A reduction and/or clearance of the latent viral reservoir (i.e.: virus that remains dormant in HIV-infected subjects receiving suppressive treatment ) is considered essential for HIV eradication. By measuring the changes in integrated proviral HIV DNA, which is considered a surrogate measure of the latent reservoir, the investigators will establish if peg-IFN-α2b treatment should be considered as a component of future viral eradication strategies.

Immunity 1 (Fuzheng 1) is composed of herbs which have tonic and detoxific function. The long-term clinical application has proved the safety and effect. It can improve the symptoms and signs in AIDS patients with the effective rate of 70% and can significantly improve the quality of life. It can also improve and stabilize immune function and inhibit viral replication. The basis study have shown that Immunity 1 (Fuzheng 1) can inhibit viral replication from multi-target, multi-link, enhance immune function, increase the secretion of IL-2, IFN-γ, participate in immune regulation effect, enhance NK cell activity, promote CD3+CD4+T cell proliferation and increase macrophage phagocytes capacity.
