View clinical trials related to Enterovirus Infections.
Filter by:Enteroviruses (EV) are the most frequent cause of acute meningitis in the paediatric population. Detection of enterovirus in cerebrospinal fluid (CSF) specimens by Polymerase Chain Reaction (PCR) is the gold standard diagnostic test. Recently, our laboratory published the BLEDI study which highlighted the interest of detecting EV in the blood of the paediatric population : (i) EV was found in more than a quarter of cases in the blood of infants admitted to hospital with isolated fever and (ii) detection of EV was more frequent in the blood than in CSF in neonates and infants with isolated fever, sepsis or meningitis. However, the pathophysiology of EV infections is poorly understood and little work has been done on the inflammatory response to these infections. In EV meningitis, the inflammatory response has been studied primarily in children infected with enterovirus A71 (EV-A71). Indeed, in these children, inappropriate cytokine secretion (cytokine storm) leads to severe neurological and cardiopulmonary damage, which can progress to death. The study of the inflammatory response during meningitis due to other types of EV remains poorly The objective of BLEDI-CYTOKINES (ancillary study of the BLEDI study) is to study the inflammatory response during EV meningitis in neonates, infants and children, as assessed by cytokine levels in blood and cerebrospinal fluid, by comparing case-controls from an existing cohort.
Neonates could be infected by non-polio enterovirus easily. Some of the neonates may develop fatal complications within one week. The objective of this study were as following: 1.To understand the composition and epidemiological characteristics of enterovirus infection in pregnant women in some areas of China; 2.To understand the transmission from mother to their neonates; 3.To understand the pathogenic spectrum composition, epidemiological characteristics and clinical characteristics of enterovirus infection in neonates; 4.To understand the genetic variation and changes of enteroviruses; 5.To establish a quality management system for maternal and neonatal enterovirus laboratory testing and monitoring.
This phase IV clinical study evaluates the safety of enterovirus 71 vaccine in children aged 6-35 months old by the method of both passive and active surveillance.
