This study will compare the benefit for patients switching from Kaletra® to Invirase® tablets over remaining on Kaletra® (based on randomization), to elicit the lipid benefits inferred in previous studies
The purpose of this study is to evaluate if the combination of Lpv/r monotherapy and anti-HCV drugs does not match with additional toxicity induced by the association of HAART and Peg-IFN + ritonavir in HIV/HCV coinfected patients. Secondary objective is to assess if Lpv/r monotherapy during HCV-treatment is associated with HIV efficacy versus optimized HAART.
The purpose of this study is to evaluate if the combination of Lpv/r monotherapy and anti-HCV drugs does not match with additional toxicity induced by the association of HAART and Peg-IFN + ritonavir in patients naive for HIV and HCV. Secondary objective is to assess if Lpv/r monotherapy during HCV-treatment is associated with HIV efficacy vs optimized HAART.
The introduction of highly active antiretroviral therapy (HAART) has dramatically changed the consequences of an HIV infection, which is now viewed as a chronic disease. As in other chronic diseases, emotional distress and depressive symptoms are highly prevalent in HIV-infected patients. Psychological factors such as these have been associated with lower quality of life, lower adherence to therapy and also with a higher risk for mortality and disease progression. Psychosocial interventions, such as group-based cognitive behavioral stress management (CBSM) training, have been shown to reduce distress and psychological symptoms in HIV-infected patients. These psychosocial effects are paralleled by changes in physiological parameters, such as cortisol, DHEA-S, testosterones, catecholamines, and naìˆve T-cell counts. While these results are congruent with recent evidence of the interaction between psychological, neuroendocrine and immunological parameters in HIV-infected patients, it needs to be shown whether the reported effects hold true in the HAART era. Most importantly, it also needs to be ascertained whether these interventions have an impact on immunological and virological HIV parameters as well as on mortality and morbidity in HIV patients. We propose a randomized controlled one-year prospective evaluation of a group-based CBSM training in 80 HIV-infected patients. Participating patients will be recruited at cooperating centers of the Swiss HIV Cohort Study and randomly assigned to CBSM training or waiting control group condition. At baseline, post-training and two follow-up (6 and 12 months) assessments, effects of the CBSM on psychological, physiological and clinical out-come variables in HIV-infected patients under HAART will be evaluated. Additionally, the effects of CBSM on the neuroendocrine and autonomic stress reactivity in HIV-infected patients will be assessed, thus evaluating a possible direct pathway between emotional distress and physiological HIV-relevant parameters. In conclusion, the planned research project evaluates the effectiveness of a standardized psychosocial intervention as a possible component of a comprehensive disease management in HIV-infected patients under HAART.
This 2 arm study will assess the effect of moderate liver impairment on the pharmacokinetics of saquinavir and ritonavir at steady state following administration of saquinavir/ritonavir 1000mg/100mg po bid in HIV patients. Saquinavir/ritonavir will be administered concomitantly with 2 to 3 active nucleoside reverse transcriptase inhibitors. The study will compare a group of HIV patients without known liver disease and a group with moderate liver disease. The anticipated time on study treatment is <3 months, and the target sample size is <100 individuals.
In this research project, we will study the genetic determinants that influence the pharmacokinetics of antiretroviral drugs used in the treatment of diseases caused by the HIV.
GSK has constructed a new HIV immunogen comprised of conserved parts of the HIV virus (gag, pol and nef). The principal objectives of this study are to evaluate the reactogenicity and safety of this candidate vaccine with or without a GSK proprietary adjuvant system at three different doses and to evaluate the CD4+ T-cell response in terms of proportion of responders to the antigens two weeks after the second vaccination.
This study will examine whether HIV-infected patients are more likely to develop resistance to antiretroviral therapy if their blood is not monitored for the number of viruses (viral load) in the body. A virus that changes (mutates) over time may become resistant to certain types of medicine. This resistance may affect future treatment options. This study will compare the amount of virus in the blood of HIV-infected patients who have been monitored for viral load with the amount of virus in the blood of patients who have not been monitored for viral load. For patients who have detectable virus, the type of resistance (mutations) of the virus will be determined by comparing the components of the virus with that of a virus that is known not to be resistant. HIV-infected patients 18 years of age or older who are being treated at the Infectious Diseases Institute at Mulago Hospital at Makerere University in Kampala, Uganda, may be eligible for this study. Participants are interviewed about the treatments they have received for HIV and how they usually take their anti-HIV drugs. They also have a blood sample drawn for research tests.
The purpose of this study is to observe the effects of certain anti-HIV medications on mitochondrial activity and fat cell death. This study will enroll participants from another study, ACTG A5202, who are on treatment regimens that do not include zidovudine, stavudine, or other thymidine-containing anti-HIV medications.
