Filter by:The study is funded through the Office of the Global AIDS Coordinator (OGAC #KE-07-0044). The purpose of this study is two-fold. The first purpose is to see if routine monitoring of the level of HIV virus in the blood (viral load) every six months is superior to monitoring by standard clinical evaluations and or immune status (CD4 count) with intermittent viral load monitoring in adults receiving antiretroviral therapy (ART). The second purpose is to understand the cost implications and possible benefits of routine HIV viral load monitoring.
This pilot study will evaluate the effects of the anti-diabetic drug Bydureon (exenatide extended-release formulation) on blood sugar levels and serum markers of inflammation in a cohort of 12 HIV-infected adults on combination antiretroviral therapy (cART) with untreated diabetes mellitus. Previous studies have shown that high levels of persistent systemic inflammation predict the development of cardiovascular and metabolic diseases in HIV-infected persons on cART (a group at very high risk of atherosclerosis and myocardial infarction). Bydureon has demonstrated potent anti-inflammatory effects in prior studies of non-HIV infected persons, which suggests that this agent may represent a unique and preferred medication for the treatment of insulin resistance in HIV-infected adults. The Investigators hypothesize that short-term (16 weeks) therapy with Bydureon will improve glucose tolerance and significantly reduce circulating plasma levels of interleukin-6 (IL-6) and highly-sensitive C-reactive protein (hsCRP), two biomarkers strongly implicated in the development of cardiovascular and metabolic diseases in diabetic, HIV-infected, cART-treated adults.
BK infection is an important cause of graft dysfunction and graft loss after renal transplantation. It has been widely accepted that emergence of BK virus correlates with the more potent immunosuppressive agents used to lower acute rejection rates. In contrast to other opportunistic infections after transplantation, for which routine prophylactic agents are administered, there is no effective agent for the prevention of BK infection. Some data, however, suggests that quinolone antibiotics such as ciprofloxacin may have activity against BK virus. This has led us to investigate whether routine, short-term ciprofloxacin administration post-transplant can lower the incidence of BK infection.
The recent swine origin influenza pandemic (2009), new emergence of swine origin H3N2v, and delayed availability of vaccine for these agents highlight the need to test and optimize public health intervention strategies to reduce transmission of influenza. We will use a new technology for biological particle collection (U.S. Provisional Patent Application No. 61/162,395, McDevitt et al., Aerosol Sci Technol 2013) to make fundamental observations on infectious respiratory droplets in a study of up to 200 naturally occurring seasonal influenza cases. We will collect respiratory droplets shed by participants while breathing normally, talking, and spontaneously coughing. We will characterize the size distribution of droplets containing infectious virus. We will use these basic data to examine the roles of large and small respiratory droplets and examine how the interaction of host factors and virus type impact the shedding of infectious respiratory droplets. Subjects will be recruited through a web based respiratory illness surveillance system, health clinics and advertisement in the campus community. Sitting in the collection booth will not create additional discomfort or risk for volunteers already suffering from influenza infection. We will recruit up to 1000 persons with symptoms of acute respiratory illness for screening with collection of nasopharyngeal swabs and questionnaire. From among those screened, we will recruit 250 to give exhaled breath samples, and ask 50 people with influenza to return for follow up exhaled breath samples on up to two subsequent days. We hypothesize that (1) fine aerosols (<5 microns in aerodynamic diameter) will contain more viral copies than coarse aerosol particles (>= 5 microns) (2) fine aerosols will contain culturable virus indicating that the fine aerosols are infectious, (3) aerosol shedding will correlate with virus load measured by swabs, (4) presence of active cough during sampling will be associated with increased aerosol shedding, (5) clinical symptoms and signs, including fever can be used to predict viral aerosol shedding.
This study is to evaluate the antiviral effect of GS-5806 in healthy adults infected with a strain of Respiratory Syncytial Virus.
The purpose of this study is to collect clinical outcome and nasal viral load information.
The purpose of this project is to gather pilot data related to risk factors associated with suicide in Veterans with Human Immunodeficiency Virus (HIV)/ Acquired Immune Deficiency Syndrome (AIDS) and to develop an educational and interventional tool and instructional guide that can be utilized by local and national providers to increase understanding regarding suicide risk assessment. There are no hypotheses associated with this qualitative pilot study.
This study is an open-label extension of RFSP-AMDX-2010 study for those subjects who received treatment with amdoxovir (300 mg or 500 mg twice daily) for 12 weeks and benefited from it. This study will examine the safety and efficacy of the investigational HIV drug, amdoxovir (300 mg and 500 mg bid doses; N = up to 30) in combination with zidovudine and lopinavir/ritonavir for 36 weeks. Subjects will continue to receive either amdoxovir 300 mg twice daily or amdoxovir 500 mg twice daily, each in combination with zidovudine 300 mg twice daily and lopinavir/ritonavir (400 mg/100 mg twice daily) for additional 36 weeks.
This is a double-blind Phase 2a study to test the safety and efficacy of an investigational HIV drug, amdoxovir (300 mg or 500 mg twice daily) compared with tenofovir DF 300 mg once daily in HIV-1 infected antiretroviral therapy-experienced subjects who are currently failing antiretroviral therapy. There are three treatment groups (N=45). Subjects will be randomized to receive either amdoxovir 300 mg twice daily (n=15) or amdoxovir 500 mg twice daily (n=15) or tenofovir DF 300 mg once daily (n=15); each in combination with zidovudine 300 mg twice daily. The study will assess initially amdoxovir (300 mg or 500 mg twice daily) or tenofovir DF 300 mg once daily, both in combination zidovudine 300 mg twice daily plus failing third drug, but then with lopinavir/ritonavir (400 mg/100 mg twice daily) after Week 2. Subjects who received amdoxovir (300 mg or 500 mg twice daily) and benefited from the drug may choose to enroll in the 36-week open-label study.
It is estimated that 350-400 million people worldwide are chronically infected with hepatitis B virus (HBV). Cirrhosis and hepatocellular carcinoma are major complications of chronic HBV infection and are responsible of about 500,000 deaths each year. Although some predictive factors of the outcome of chronic HBV infection were reported, it remains needed to more precisely determine the factors which are associated with the outcome in non-selected patients. Indeed, these factors should help to identify patients who are likely to have a better or worse evolution of their chronic HBV infection over time and thus, to adapt their clinical management and monitoring.Therefore, our purpose is to constitute a "real-life" cohort of non-selected patients to create a database of epidemiological, clinical, biological, virological and therapeutic parameters, in order to determine factors associated with the outcome of chronic HBV infection.
