Filter by:The Geneva Blood Virome Project is a longitudinal observational study. The main objective is to describe the kinetics of the plasmatic viral load of a selection of at least 21 DNA and RNA viruses of the blood virome in allogeneic hematopoietic stem cell transplant recipients, over a one-year period after transplantation. Secondary objectives are: 1) to assess the prevalence of DNA and RNA viruses plasmatic detections and co-detections, 2) to assess the cumulative incidence of DNA and RNA viruses plasmatic detection. The population of the study consists in adult patients receiving allogeneic stem cell transplantation at the University Hospitals of Geneva, enrolled in an already existing monocentric cohort, and for which clinical specimens are collected and stored at the time and after transplantation. The investigators plan to include 120 patients whose plasma samples are collected from March 2017 and to systematically use plasma samples collected on the day of transplantation and several time points after transplantation to screen DNA and RNA viruses by qualitative and quantitative real-time PCR and RT-PCR.
Study setting: Medellin and Bello municipalities, Colombia Health condition(s) studied: Dengue, Zika and chikungunya virus infection Intervention: Deployment of Wolbachia-infected Aedes aegypti mosquitoes in Medellin and Bello. Study design: 1. An interrupted time-series analysis utilising routine disease surveillance data collected by the Medellín and Bello Health Secretariats, which aims to compare incidence of dengue, chikungunya and Zika pre- and post-Wolbachia release. 2. A test-negative study using an incident case-control design, which aims to quantify the reduction in disease incidence among people living within a Wolbachia-treated zone compared with an untreated zone that has a similar dengue risk profile at baseline.
The study is a randomized controlled trial of pediatric patients ages birth to two years of age who are mechanically ventilated and sedated as a result of a respiratory virus. The experimental group will receive twenty minutes of live, preferred music with a board-certified music therapist and the control group will receive twenty minutes of recorded music, also preferred, both interventions conducted at bedside. Caregivers will take a pre and post survey.
Currently, there are no licensed therapeutics against Zika virus infection. Due to this unmet medical need, Zika Virus Immune Globulin (ZIKV-IG) is being developed as a therapeutic intervention against Zika virus infection. In this first-in-human study, evaluation of ZIKV-IG safety and pharmacokinetics (absorption, metabolism and excretion) will be conducted in healthy adult volunteers.
This study will evaluate the anti-retroviral activity of MK-8527 in HIV-1 infected, ART-naïve participants. The primary hypothesis is that MK-8527 has superior anti-retroviral activity compared to placebo, as measured by change from baseline in plasma HIV-1 ribonucleic acid (RNA) at 168 hours postdose.
This prospective, non-randomized, non-controlled clinical trial was conducted to examine the clinical outcomes achieved by using initial high-dose intravitreal ganciclovir injections of ganciclovir in treating cytomegalovirus (CMV) retinitis in patients without human immunodeficiency virus (HIV) infection.
Egypt has the highest prevalence of hepatitis C virus (HCV) in the world. In 2015, the prevalence of HCV RNA was found to be 7.0%.(1) The prevalence of HCV was studied in Rheumatoid arthritis in few studies(2,3), but to our knowledge, no previous work studied it in other rheumatologic diseases.
A randomized, double-blind, phase II clinical trial was conducted versus placebo in 110 patients with esophageal human papillomavirus. The experimental group will receive the VIUSID® plus GLIZIGEN® nutritional supplements, administered on an outpatient basis for 3 months. The control group will receive placebo from Viusid plus Glizigen placebo. It is expected that patients in the experimental group have a 30% higher rate of elimination of the virus than patients in the placebo group after treatment. The study will be conducted in the Superior Digestive Tract consultation of the Institute of Gastroenterology of Havana, Cuba.
Epstein-Barr virus (EBV) is one of several herpesviruses that cause disease in humans. EBV virus has an oncogenic potential, and it has been associated with the development of a wide range of cancers. Previous studies have shown a close association between EBV and Post-Transplant Lymphoproliferative disorder (PTLD) in transplant recipients. As part of a preventive approach against PTLD, several transplantation units now monitor the occurrence of EBV-DNAemia after transplantation. However, there is little evidence to guide this strategy; nor is there consensus concerning either the best specimen to use for EBV analysis (whole blood or plasma). In this study investigators aim to optimise and validate a polymerase chain reaction (PCR)-test for EBV-DNA on, respectively, whole blood, plasma and a combination of plasma and lymphocytes. The investigators wish to determine which of the three tests best predicts current and future risk of development of EBV-related diseases such as mononucleosis and PTLD.
This research study is evaluating the reactivation of BK virus in patients who have undergone allogeneic hematopoietic-cell transplantation.
