NCT ID: NCT03642977 Completed - Clinical trials for RNA Virus Infections

DNA and RNA Viruses of the Blood Virome of Allogeneic Hematopoietic Stem Cell Transplant Recipients

GeBVir
Start date: March 1, 2017
Phase:
Study type: Observational

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.
