Filter by:Transplant recipients are treated with immunosuppressive drugs to avoid rejection of the transplanted organ. As the medication impairs the immune response, it also increases the risk of serious infections and cancer in transplant recipients compared with the general population. Previous studies have shown a close association between Epstein-Barr virus (EBV) and post transplant lymphoproliferative disorder (PTLD), with frequent demonstration of the virus in lesional tissues. Transplant recipients without evidence of EBV infection prior to transplantation (EBV seronegative) are at particularly high risk of developing PTLD. Other risk factors include a high viral load. 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) or the appropriate clinical action to take if EBV DNAemia is detected. Our aim is to estimate the incidence and clinical consequences of Epstein-Barr virus (EBV) DNAemia in whole blood and plasma in renal transplant recipients, and to determine if persistence of EBV DNAemia can predict excessive immunosuppression as indicated by the incidence of infections requiring hospitalisation, EBV driven PTLD and mortality.
This Phase 2 study aims to improve preparedness for future Ebola outbreaks by vaccination of a well-known population at risk, ie, a cohort of health care providers (HCP) (such as primary, emergency, and community health care workers) who may be exposed to Ebola in the event of a future outbreak in the Democratic Republic of the Congo (DRC). This study will enhance the immunogenicity database by investigating the kinetics of the humoral immune response. The study will contribute to the safety database (serious adverse events) for VAC52150 following a heterologous vaccine regimen with Ad26.ZEBOV as first vaccine followed by second dose with MVA-BN-Filo administered 56 days later (Day 57). Additionally, after randomization (1:1), a booster vaccination with Ad26.ZEBOV will be executed at 1 year post first dose or 2 years post first dose.
Zika virus (ZIKV) infection spread throughout the Americas with devastating consequences. Recent limited evidence suggests the potential for neurological effects associated with postnatally acquired ZIKV infection in humans; however, the impact on children is unknown. The researchers will conduct a longitudinal study of approximately 450 Nicaraguan children who were ages 2-12 in 2016 to evaluate the presence and persistence of neurological symptoms associated with ZIKV infection and to test whether ZIKV-infected children are at greater risk for developing neurological outcomes compared to uninfected children.
This is a single center, single arm, open-label, phase I study to evaluate the safety and efficacy of EBV-TCR-T cells in patients with EB virus infection after HSCT.
This is a single cente, single arm, open-label, phase I study to evaluate the safety and effectiveness of CMV-TCR-T cell immunotherapy in treating CMV virus infection after HSCT.
A single arm, open-label, non-randomized, interventional phase 3 study to measure safety and effectiveness of a heterologous, two dose preventative vaccine (Ad26. ZEBOV, MVA-BN®-Filo) against Ebola Virus Disease.
The VRS (Respiratory Syncytial Virus) study group in Lyon is a working that aims to understand, predict and prevent the burden of disease caused by human respiratory syncytial virus (RSV) infection in infants. Incidence of RSV-associated hospitalization in the first year of life was estimated at 14.5 (95% CI 13.4-15.6) per 1000 births in a cohort study in Lyon, France. Related direct medical annual costs were estimated for this cohort at 364,269€, mostly attributed to children born during the RSV season (231,959€) and children born premature (108,673€). This study will combine existing hospital specimens and databases to determine the respective role of socio demographic factors, clinical risk factors, level of cord specific antibody at birth, and virus characteristic in the Respiratory Syncytial Virus (RSV) Hospitalization outcome in Infants. Regarding the introduction of a new RSV vaccine and RSV-specific neutralizing antibodies, these data are of prime importance to guide future vaccine policies.
This study will evaluate a home-based approach to influenza infection control, using prepositioned home-based influenza self-test kits, telemedicine services, and rapid delivery of Xofluza (Baloxavir marboxil) for administration within 48 hours of symptom onset.
This study is a stepped-wedge cluster-randomized trial of on-site rapid testing and treatment for influenza in homeless shelters within the Seattle area to determine whether this strategy reduced the incidence of influenza in the shelter environment.
Aim of this study is to investigate safety and efficacy of A. Vogel Sore throat lozenges for the treatment of of acute sore throats
