Filter by:Advances in HAART have been a huge success story in the management of HIV infection. However, serious metabolic complications including osteoporosis and bone fractures are increasingly been seen with HAART, and the responsible mechanisms remain poorly elucidated. The skeleton continually regenerates through homeostatic bone remodeling. Osteoclasts the cells responsible for bone resorption form under the influence of the key osteoclastogenic cytokine Receptor- Activator of NF-KB (RANKL). The osteoclastogenic and pro-resorptive activities of RANKL are moderated by its physiological decoy receptor osteoprotegerin (OPG). Increase in the ratio of RANKL to OPG accelerates the rate of osteoclastic bone resorption leading to osteoporosis. The investigators' preliminary studies have now demonstrated that in an animal model of HIV/AIDS, the HIV-1 Transgenic rat, the development of osteoporosis is recapitulated as observed in human patients. Furthermore, the investigators found that B cell expression of OPG is significantly downregulated, concurrent with a significant upregulation in production of RANKL.
This pilot, phase I trial studies the side effects and best dose of bortezomib in treating patients with acquired immune deficiency syndrome (AIDS)-related Kaposi sarcoma that has come back or has not responded to treatment. Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
In subjects on boosted protease inhibitor (PI)-regimens who have elevated triglycerides, a switch to fosamprenavir/ritonavir once daily followed by the addition of Lovaza will result in 30% of patients achieving a reduction in fasting triglycerides < 200 mg /dL while maintaining virologic suppression.
Objective: To evaluate the efficacy and safety of high doses of both peginterferon-alfa 2a (360 ug per week) plus ribavirin (800 mg b.i.d.) in HIV-infected patients with compensated liver cirrhosis by HCV genotype 1 or 4 without previous virological response(*) to a standard dose treatment of both drugs. (*) Non previous virological response: no decrease of plasma RNA-HCV at least 2 log10 after 12 weeks in treatment or breakthrough viremia while on treatment. Additionally, this study will evaluated the influence of simultaneous peginterferon-alfa 2a and ribavirin plasma concentrations on early viral response (EVR) and sustained viral response (SVR) in these patients. Method: Pilot clinical trial, phase II-III, open labeled multicenter in which patients from several hospitals of the Servicio Andaluz de Salud will be enrolled. The usual clinical and analytical follow up will be performed but additional blood samples will be obtained for determination of interferon and ribavirin plasma levels. The primary end point will be a sustained virologic response (defined as an undetectable serum HCV-RNA after 24 weeks after the cessation of treatment). Likewise, rapid virological response (at 4 weeks of treatment), early virological response (at 12 weeks), and end of treatment response rates will be evaluated as well as their relationships with the plasma interferon an ribavirin concentrations determined by ELISA and HPLC, respectively. The safety and tolerability of the studied medications will be evaluated by means of clinical adverse events, physical examination and laboratory results. The evolution of liver fibrosis will be evaluated comparing the basal and end of treatment results of transient elastometry.
To reassess nutritional status of HIV-infected Thai children living in the family style community after receiving nutrition support program for 6 months.
Main objective: To study and validate a questionnaire measuring treatment adherence in patients with Hepatitis C virus (HCV) infection. Design of the study: Multicentric, prospective, epidemiological study in the field of usual clinical practice.
Infection with hepatitis C virus (HCV) can cause liver scarring, or cirrhosis, and this usually occurs more rapidly among people infected with both HCV and human immunodeficiency virus (HIV). People infected with both HCV and HIV have poor response to the current HCV treatments. This phase II pilot study evaluated whether adding a new HCV medication improves response to the current standard HCV treatment with pegylated interferon and ribavirin in people with both HCV and HIV.
Primary objective of the study is: To verify if simplification of the antiretroviral regimen, measured as the reduction of pill burden alone, may affect adherence rate of patients.
This study is funded by the American Heart Association. The goal of this research is to prevent early cardiovascular damage before symptoms develop for persons with HIV infection. Evidence suggests that taking low doses of blood pressure and cholesterol medication reduces risk for heart disease in persons who are at increased risk (such as the case with HIV infection). Participants who are taking HIV treatment with an 'undetectable' viral load, and who do NOT need treatment for high blood pressure or cholesterol may be eligible to enroll. Participants will take a low dose cholesterol medication (or placebo) and a low dose of a blood pressure medication (or a placebo), and will be seen at 3 study visits over 4 months.
The aim of this study was to delineate the epidemiological profile of HIV seropositive patients on antiretroviral therapy at the Clinical Hospital of the Federal University of Goiás.
