Active clinical trials for "Respiratory Syncytial Virus Infections"

The purpose of this study is to determine the utilization patterns and compliance rates of palivizumab, which is a monoclonal antibody therapy used to prevent respiratory syncytial virus infection.

The purpose of this study is to describe respiratory syncytial virus (RSV) hospitalization rates and to begin to address the utilization of outpatient resources for RSV medically-attended lower respiratory tract infections (MALRI) in 32-35 week gestational age (GA) premature infants who are less than 6 months of age and do not receive treatment.

This study will investigate whether there is a population-level association between circulating respiratory viruses and NHS hospital admissions for acute vascular events using data from national infection surveillance and Hospital Episode Statistics.

Respiratory syncytial virus (RSV) infection is the most common cause of severe lower respiratory tract infection (LRTI) in the pediatric population worldwide. Age at the time of infection, prematurity, multiparity, exposure to smoke and the level of passive immunity transmitted at birth are the main risk factors for lower respiratory infection associated with RSV. Other factors, including the innate immune response, respiratory microbiota, and intra-host viral heterogeneity, may also affect outcomes but are not fully considered in RSV infection. Exploring the impact of these factors is difficult due to the heterogeneity of the population which makes statistical adjustment difficult. Thus, twin models are useful in understanding the impact of the host on the environment, as twins often share similar exposure to infection and many risk factors, but not all are ie different prenatal and postnatal conditions, differential transfer of maternal antibodies and the genetic makeup of heterozygotes.

The SYNAGIS Registry was carried out in order to gather comprehensive real-world data on the use of palivizumab in children at high risk for serious respiratory syncytial virus (RSV) disease. This registry was designed as a post-marketing observational study, and conducted with the aim of collecting data on palivizumab administration, the risk factors for complicated RSV disease, frequency of hospitalizations, and drug adherence.

The magnitude of seasonal Respiratory Syncytial Virus (RSV) epidemics brings each year new logistical challenges for the hospitalization of young infants with bronchiolitis that overwhelm hospital capacities and lead to specific winter plans with deprogramming and mobilization of human and logistical resources. The Covid-19 pandemic has changed the way winter epidemics are presented. For example, the seasonal RSV epidemic was shifted by several months in Lyon, with an impression of a lower incidence of hospitalized cases, with a population of older children and with fewer signs of clinical severity. This is largely attributable to the widespread use of barrier gestures and social distancing measures, known as "Non-Pharmacological Interventions" (NPI). Given the magnitude of the reduction of the RSV epidemic, it is legitimate to analyze the benefits of NPIs to draw lessons for maintaining preventive measures around RSV-vulnerable populations; moreover, new preventive pharmacological interventions are soon to be marketed, whether they are particularly refined and long half-life anti-RSV monoclonal antibodies, RSV vaccines for mothers or for newborns and infants. In this perspective, it is crucial to properly define the populations at risk of severe disease to establish a legitimate hierarchy in the implementation of different preventive strategies. The study of the RSV epidemic is a high potential model because of the convergence of epidemiological, virological, and pharmacological knowledge. However, the study of the impact of the pandemic on the epidemiology of rhinovirus also seems promising because, for reasons unknown to date, it seems that the pandemic did not have the same reducing impact on the rhinovirus epidemic; in the latter case, the interest is to confirm the resistance of this virus and to look for more fundamental explanations, for example, on viral interactions.

The principle purpose of this multicenter trial is to determine the definition, timing and the percentage of nosocomial RSV epidemics throughout Turkey. In addition, secondary purpose of the trial is to determine the prevention strategies of further spread of Respiratory Syncytial Virus (RSV) in the neonatal intensive care unit (NICU).

The primary objective of this study is to determine the incidence of severe RSV LRTI requiring hospitalization among infants born < 35 weeks gestational age for one year of follow-up.

Given the possible prognostic relationship between exhaled breath condensate pH and clinical symptoms, it is quite plausible that exhaled breath condensate pH can prove useful in the intensive care unit. For example, if exhaled breath condensate pH falls prior to the onset of clinical symptoms, it is likely that it can be useful as an early marker, heralding the onset of various inflammatory lung diseases. Specifically, exhaled breath condensate pH could be used as a safe, non-invasive screening tool for Ventilator Associated Pneumonia. Similarly, just as changes in exhaled breath condensate pH might predict the onset of disease, exhaled breath condensate pH changes might also mark the progression or resolution of disease (e.g. alerting clinicians to possible readiness for extubation). Although such notions are hypothetical, they are beginning to be supported by anecdotal evidence.

This study evaluates a single use point of care diagnostic test in the diagnosis of influenza and other respiratory viral infections in adults. Participants will have a sample taken from their nose using a swab. The swab will be gently mixed in a liquid solution which will then be transferred into the device for testing.
