Filter by:Young men who have sex with men (MSM) in low- and middle-income countries often do not seek out HIV testing, are unaware of their HIV-positive status, and do not receive early medical care, compromising their health and contributing to downstream disease incidence. This situation is of great concern in post-socialist countries of Eastern Europe, where stigma about HIV/AIDS and same-sex behavior are great, HIV epidemics are still increasing, and the health needs of young MSM are rarely acknowledged or addressed. The planned research will be conducted in Sofia, Bulgaria, where MSM account for nearly half of HIV infections. The study will be conducted in two phases.
Male participants taking tenofovir-emtrictabine (TDF/FTC) will provide semen and blood samples which will be analyzed to better understand the pharmacology of antiretroviral therapy in the male genital tract.
Despite potent combination antiretroviral therapy, cognitive (memory and concentration) problems continue to occur in up to 50% of HIV-infected individuals, especially in older infected individuals, and those who abuse alcohol, marijuana or psychostimulants. Since no effective treatments are available to these individuals with cognitive problems, conservative estimates indicate that the cost of care for these patients could double in the next two decades. To address this urgent problem, this study will use a comprehensive approach (cognitive tests, functional MRI and several biomarkers) to evaluate whether a novel computer-based training program would improve the brain function, especially working memory and attention, in HIV-infected and infected individuals.
Long term toxicity of combination antiretroviral therapy (cART) is a substantial contributor to morbidity and mortality in chronically infected HIV positive individuals. To date it is still debated, whether long term nucleoside reverse transcriptase inhibitors (NRTI's) -sparing regimens are practicable or even superior compared to standard of care cART in terms of efficacy, safety and tolerability. In addition, data about efficacy of integrase inhibitor (INSTI) based monotherapy is lacking. We aim at investigating the efficacy of standard of care combination antiretroviral therapy with a simplified dolutegravir monotherapy in patients with a primary HIV-1 infection under suppressive early standard of care antiretroviral therapy. Briefly, hundred-thirty-eight patients with a documented primary HIV1- infection (PHI) will be recruited from the Zurich Primary HIV-1 Infection Study (ZHPI), which is an open label, non-randomized, observational, single-center study (http://clinicaltrials.gov, ID 5 NCT00537966). All subjects formerly underwent early cART consisting of either a protease inhibitor (PI) or a non-nucleoside reverse transcriptase inhibitor (NNRTI) or a INSTI in combination with two NRTIs at the time point of enrolment in the ZPHI and must be under a fully suppressive ART (i.e., <50 copies/ml) for at least 48 weeks at the time point of randomisation. The primary end point is the proportion of individuals with a viral failure at week 48 or before.
The purpose of this study is to provide continued access to rilpivirine (RPV) for participants who were treated with RPV in a clinical development pediatric study with rilpivirine and who, at the time of roll-over, experience and are expected to continue experiencing clinical benefit from RPV treatment.
This phase II trial studies surgery in treating patients with anal canal or perianal cancer that is small and has not spread deeply into the tissues and human immunodeficiency virus (HIV) infection. Local surgery may be a safer treatment with fewer side effects than bigger surgery or radiation and chemotherapy.
Despite efficient antiretroviral treatment for HIV infection, decrease in life expectancy remains. Excess mortality is mainly due to non-AIDS co-morbidity including cardiovascular, pulmonary, and liver related diseases. Both HIV-unrelated and HIV-related risk factors probably contribute to this pattern. At present, most evidence regarding co-morbidity in HIV infection rely on cross-study comparisons of HIV-infected persons with published population rates and few prospective studies in U.S. cohorts. Using well characterized participants from the Copenhagen General Population Study (CGPS) as controls, we aim to include >1500 HIV-infected persons in the COCOMO study to determine if co-morbidity is more prevalent or develops at a higher rate in HIV-infected persons. The study will asses 1) cardiovascular, 2) pulmonary and 3) liver-related co-morbidity using uniformly collected data in the two cohorts. The investigators aim to study the relative impact of HIV-unrelated and HIV-related factors on development of co-morbidity.
The purpose of this study is to determine whether the BMS Attachment Inhibitor (BMS-663068) is effective in the treatment of heavily treatment experienced HIV-1 patients with multi-drug resistance.
This study is a Phase 2b, multi-center, extension study designed to evaluate the long-term efficacy, safety, and tolerability of PRO 140 monotherapy for the maintenance of viral suppression in patients who were stable on combination antiretroviral therapy and completed 12 weeks of treatment under PRO140_CD01 Treatment Substitution Study without experiencing virologic failure. Consenting patients will continue to receive PRO 140 monotherapy for 160 additional weeks. Total treatment duration with PRO 140 will be up to 161 weeks with one week overlap of existing retroviral regimen and PRO 140 at the end of the treatment extension phase in subjects who do not experience virologic failure.
In this study the investigators will determine risk factors for liver fibrosis among HIV-HBV co-infected patients in Lusaka, Zambia, and assess the long-term effectiveness of antiretroviral drugs in the prevention and/or reduction of liver disease.
