Filter by:A switch from protease inhibitors (PIs) to raltegravir (RAL) will be effective virologically and immunologically. Moreover, it will be associated with significant improvements in the lipid profile in HIV patients with undetectable viremia on PIs. In this setting, RAL once a day (QD) will perform as well as RAL twice a day (BID).
The investigators will evaluate the effects of an endurance exercise program on the physical performance, the well being, and indicators of metabolic function in patients with an HIV infection.
The Mediational Interventions for Sensitizing Caregivers (MISC) model developed by Professor Pnina Klein is to enhance the cognitive and social development of children throughout the developing world . Although MISC has proven effective in a longitudinal study in two poorer communities of Addis Ababa, Ethiopia , it has not been used with HIV households or in the Ugandan context where there is desperate need for enhanced caregiving in HIV-affected families. We propose to work with community leaders, healthcare workers, and parents/caregivers in adapting MISC to the Ugandan cultural and social context in Kayunga. For intervention families, MISC training will be added to an ongoing home health care visit (HHCV) program already in place for HIV children in Kayunga district. We will then evaluate whether MISC parent/caregiver training improves cognitive and psychosocial development in their children, and whether clinical stability of the HIV child is an important modifier for MISC training benefit.
Hypothesis: the efficacy of 2 doses 7-valent PCV is equivalent to 1 dose 7-valent PCV.
- The aim of the study is to compare the effects of coadministration of ezetimibe 10 mg/die + fenofibrate 200 mg/die versus pravastatin 40 mg/die monotherapy in HIV-infected patients treated with protease inhibitors. - Single-centre, open, randomized, controlled, prospective pilot study. - 60 patients will be enrolled in order to reach the target of 50 patients evaluable at the end of the study. The patients will be randomly assigned to a 6-month treatment with ezetimibe+fenofibrate or with pravastatin.The visit will be every month.
The investigators seek to determine whether Virco®TYPE HIV-1 provides benefits equivalent to those provided by local expert review. The investigators propose that clinic patients of the Ruth M. Rothstein CORE Center who are having genotypic testing performed will be randomized in a 1:1 fashion to local expert review and to Virco®TYPE HIV-1. Results of either method will be shared with primary HIV care providers. Patient outcomes will be reviewed at a time point equal to or greater than 2 months and 6 months following the change in antiretroviral medications following the testing
Background Low concentrations of protease inhibitors (PIs) or nonnucleoside reverse transcriptase inhibitors (NNRTIs) are associated with an increased risk of virological failure. Likewise, excessive antiretroviral drug concentrations increase the risk of toxicity. Therapeutic drug monitoring (TDM) may identify and correct excessively high or low PI and/or NNRTI concentrations, and thus minimize toxicity and risk of treatment failure. Treatment guidelines only recommend using TDM to help optimize ARV therapy in selected patients, and there are no clear recommendations to guide the clinician who decides to adjust drug doses. Prospective studies have demonstrated the relationship between EFV plasma concentration and neuropsychiatric symptoms. Moreover, EFV is metabolized mainly by cytochrome P450 2B6 and its concentration was reported to be associated with the CYP2B6 516GrT genetic polymorphism. For drugs such as EFV or LPV/r, lower doses than the ones validated for standard clinical use have demonstrated efficacy in dose-ranging studies. The investigators will use a standardised algorithm to reduce doses in patients with plasma EFV or LPV/r concentration above percentile 75. This algorithm is based on a Bayesian approach from the pharmacology unit in Lausanne. The investigators hypothesize that a dosage individualisation is feasible and safe. 2.2 Study Aims The investigators aim at testing a simplified algorithm for dose reduction in patients with documented virological efficacy, treated by a stable LPV/r or EFV based regimen with elevated plasma concentration of these drugs. Study Design Prospective open label study in which all eligible patients screened with a plasma drug concentration of either EFV or LPV/r above percentile 75 will be included. After confirmation of the results at baseline, patients will be offered to decrease drug dosage by a third or a half according to a standardised algorithm. All patients will undergo HIVRNA, biochemistry and validated questionnaires after 3 and 6 months to assess the safety and the benefit of this strategy.
Due to the potential for pregnancy-induced changes in the pharmacokinetics of medication, one cannot assume that the currently licensed doses of the medication to be tested under this protocol lead to adequate exposure in an HIV-infected pregnant woman. For the agents under study no or limited pharmacokinetic data during pregnancy are available. As the changes in pharmacokinetics during pregnancy are most prominent in the third trimester a pharmacokinetic curve will be recorded in the third trimester after attaining steady state.

To describe the impact of standard HAART versus mega-HAART initiated during the acute HIV infection period on immunological and virological outcomes.
