Filter by:This study aims to prove that, by a one-time topical spray on the cervix, AV2-DM is an effective antiviral in reducing on short term (3 months) the human papillomavirus (HPV) infection. - Primary endpoint: significant drop in viral load AV2-DM versus placebo - Secondary endpoint:the number of patients with adverse events
For the development of a Point of Care IVD test kit for acute phase disease detection against a variety of bacterial and viral infections. Phase one includes 100 clinical diagnosed positive and 200 clinically "normal" serum and whole blood matched specimens for specificity and sensitivity determination for each marker. The positive samples must be IgM positive using any FDA cleared ELISA test kit. The negatives samples must be negative for IgM.
The goal of this research is the attempt to implement a new research method based on modern electrochemistry successes, in particular the development of the polarographic method of fructose and fructose diphosphate identification and its implementation to detect the viral infection in early stage. There will be 20 samples from the HIV-infected patients and 30 samples from the heath controls. The study will collect 10ml urine and examined fructose and fructose-diphosphate using the polarographic method.
This study is examining the safety and efficacy of converting anti-rejection therapy from mycophenolic acid (MPA) to Zortress (everolimus) in renal transplant recipients with BK virus infection. The study will also determine if immune monitoring tests can detect an association between BK virus infection and transplant rejection episodes, based on the specific BKV infection treatment regimen. The investigators hypothesize that an anti-rejection regimen with Zortress (everolimus) and tacrolimus + prednisone will be superior to a standard regimen of reduced dose MPA and tacrolimus + prednisone in patients who have undergone renal transplantation and have active BKV infections.
Chronic allograft injury is the leading cause of graft loss in renal transplantation. The shortage of available kidneys for transplantation has reached crisis levels with increasing numbers of waiting list mortalities. Strategies to prolong graft survival are urgently needed. The pediatric and young adult transplant population is one in which repeat transplantation is inevitable and therefore, this group is one who will especially benefit from intervention to prolong graft survival. The hypothesis of this proposal is that subclinical viral infection is a modifiable risk factor in the pathogenesis of chronic allograft injury. The young age of the proposed study population is an ideal one to evaluate this objective due to the high prevalence of seronegative recipients. The studies outlined will determine the temporal relationship betWeween subclinical viremia, renal allograft infection and allograft injury. This will be the first prospective study in renal transplant recipients to systematically monitor subclinical viral infection both in peripheral blood and in the renal allograft with concurrent quantitative measures of renal function, allograft fibrosis, and innate immune activation. The investigators have chosen these 3 outcomes because they evaluate a spectrum of renal allograft injury and represent different stages - from early to late - in the pathophysiology that leads to renal allograft dysfunction. In addition, the role of virus specific T cell immune responses in the control of subclinical viral infection and associated allograft injury will be determined. These data are critical as they will provide insights into the pathogenesis of injury and will guide development of interventions strategies. Importantly, the current treatment strategies for viral disease do not prevent subclinical viral infection. Thus, the results of this study may identify that prevention, prophylaxis and/or treatment of subclinical viral replication as a long term strategy to prevent chronic allograft injury and prolong graft survival.
The purpose of this study is to verify the long-term safety of a 2.5 µg, adjuvanted (aluminium hydroxide) dose of Ross River Virus (RRV) vaccine.
Entecavir(ETV) plus Tenofovir Disoproxil Fumarate(TDF) combination will show effective antiviral activity and prevent further development of antiviral resistance in hepatitis B e antigen(HBeAg)-positive or -negative Chronic Hepatitis B(CHB) patients who experienced multidrug resistance All subjects will orally take investigational drugs once daily for 48 weeks. All subjects will be assessed at baseline, Week 4, 12, 24, 36 and 48. Evaluations at each visit will include vital signs, physical examinations, laboratory tests and HBV DNA levels. They were also questioned about adverse events and concomitant medications. At baseline and every six months thereafter, serum will be assayed for HBV serology. Genotypic analysis will be performed at baseline and 48 weeks.
Dose cohorts may be dosed with one of up to 4 possible total weekly doses (0.3 mg, 1 mg, 2 mg, 4 mg). Dose escalation or repetition will be governed by pre-specified safety and activity rules. Subjects will be confined on days 1-3 and/or days 8-10. Follow-up visits are required periodically through day 43. Subjects with sustained reductions in HbsAg will be requested to return for additional follow-up follow-up visits at 3 and 6 months post last dose. Study procedures involve blood draws for pharmacokinetic, pharmacodynamic, virologic, and safety assessments
The purpose of this study is to determine whether FVH1, a DNA-based influenza vaccine, will be safe and generally well tolerated in healthy elderly adult volunteers and will result in greater immunogenicity when used to prime the immune response to a dose of a trivalent inactivated seasonal vaccine.
This 4-year project will be guided by a biobehavioral model for the study of exercise interventions in two phases with the purposes to : 1. explore the patients' physical activity preferences and develop doable activity lists during treatment period 2. examine the changes of health-related physical fitness component over interferon treatment 3. develop the Personalized Physical Activity and Psych-Education (PPAPE) Program and test its effects on decreasing fatigue, physical and psychological distress, and improving their health-related physical fitness and quality of life in patients with chronic hepatitis C receiving Interferon with Ribavirin Combination Therapy 4. evaluate the outcome of the PPAPE program on increasing adherence to therapy, the sustained virological response (SVR) in 24 weeks after the end of treatment, and the time-consuming for education program during intervention.
