Filter by:Primary Objective: -Estimate the hospital-associated healthcare resource use (HCRU), and associated costs, of RSV infection in children in comparison to the non-RSV control cohort (general population) and patients with rhinovirus infection. Secondary Objectives: - Describe demographic and clinical patient characteristics of RSV infected children. - Estimate and compare the incidence of RSV infection and acute respiratory infections (ARIs) in children. - Estimate the mortality associated with RSV infection in children. - Estimate the social economic burden of RSV infection in children in relation to parents staying home from work to care for their sick child (VAB leave) in comparison to non-RSV control cohort (i.e. parents to children in the general population). - Estimate the net days with VAB leave and the compensation disbursed (temporary parental benefit) associated with RSV infection in children. - Estimate the indirect costs that can be attributed to VAB leave. - Examine the medium- and long-term complications associated with an RSV diagnosis in children in comparison to the non-RSV control chart (general population) and patients with rhinovirus infection. - Examine and describe risk factors associated with an RSV infection in children - Estimate the healthcare resource use (HCRU), and associated costs, of RSV infection in children, for a subset of patients where primary care data is available, in comparison to the non-RSV control cohort (general population).
The Belgian Severe Acute Respiratory Infections network (BELSARI-net) was implemented during the influenza season 2011-2012 following the recommendations of the World Health Organization (WHO) to monitor severity of influenza viruses in hospitals. The network is composed of 6 hospitals throughout the country, two in each administrative region (Flanders, Wallonia and Brussels-Capital), and operates during the influenza epidemic period (from the last week of December or first/second week of January to the third/last week of April, depending on when influenza virus circulation is detected by the general population, based on the Influenza-like illness (ILI) network of general practitioners). Enrollment is performed for all cases matching the SARI case definition (based on WHO's case definition) and accepting to take part. A respiratory specimen is sampled systematically from each participant, and detailed clinico-epidemiological data, such as information on age, sex, symptoms and potential risk factors such as pregnancy or comorbidities (chronic respiratory diseases, asthma, chronic cardiovascular diseases, renal insufficiency, obesity, diabetes, hepatic or renal insufficiency, immunodeficiency, neuromuscular disease, pregnancy) is also collected. Participants are followed up during hospitalization for the occurrence of complications (detection of pneumonia based on chest radiography, development of acute respiratory distress syndrome (ARDS), requirement for respiratory assistance and/or for extracorporeal membrane oxygenation (ECMO), admission in intensive care unit (ICU)), or death (all-cause death). The current project includes all the samples received by the Belgian National Influenza Centre (NIC) during the influenza seasons 2011-2012 till 2019-2020.
The SARS-CoV-2 (Severe acute respiratory syndrome coronavirus type 2) infection was in 2020 responsible for new disease related chronic conditions which have been referred to as Post-COVID. To date it is still unknown how common this condition is and how it might effect the working of the Immune system. The aim of the study is therefore to monitor the onset of autoimmune diseases in a large observational study consisting of German health insurance data.
This is a phase 2A, double-blind, randomized, placebo-controlled study of molnupiravir (MK-4482) in healthy participants who have been inoculated with an experimental Respiratory Syncytial Virus (RSV) [RSV-A Memphis 37b]. It is hypothesized that MK-4482 will reduce the peak viral load (PVL) compared to placebo when given either before (prophylactic) or after (treatment) RSV-A Memphis 37b inoculation. Participants arrive at the study center for check-in between Day -3 and Day -1. The assigned treatment sequence (consisting of a combination of molnupiravir or placebo) begins Day -1. Participants receive viral inoculation with RSV-A Memphis 37b on Day 0, and depart on Day 12. There is a follow-up visit on Day 28.
Comparative study of the pharmacokinetics of XC8, film-coated tablets, 10 mg and XC8, film-coated tablets, 40 mg, when administered once in equal doses (40 mg) on an empty stomach in healthy volunteers.
This study will assess the immunogenicity, safety and tolerability of VN-0200 after intramuscular injections in Japanese healthy elderly subjects.
The main purpose of the study was to evaluate the effectiveness of XC221, tablets, at a dose of 200 mg/day compared to placebo in patients with uncomplicated influenza or other acute respiratory viral infections (ARIs). An additional purpose of the study was to evaluate the safety of XC221, tablets, at a dose of 200 mg/day compared to placebo in patients with uncomplicated influenza or other ARIs.
Study to assess the efficacy and safety of a multiple dose regimen and a single dose regimen of intranasal Neumifil, administered prior to challenge with Influenza virus in healthy adult participants
Rapid diagnosis and precise treatment have become possible with multiplex polymerase chain reaction (PCR) panels that can identify a variety of causative agents of acute respiratory illnesses such as bacterial and viral infections in one urgent care visit. While real-time PCR is currently used as a standard for diagnosing acute respiratory illnesses such as influenza due to its high sensitivity and specificity, it typically takes several hours for results which is unfavorable in the urgent care setting. Highly sensitive and rapid random-access PCR tests provide the sensitivity and specificity needed to both rapidly and accurately diagnose acute respiratory illnesses. Similar PCR panels have been used in previous research for the diagnosis of gastrointestinal illnesses in the emergency department and point-of-care testing for hospitalized adults presenting with acute respiratory illness. In this study, the investigators aim to determine if a rapid multiplex PCR test for urgent care patients with symptomatic upper respiratory infections can improve patient and provider-reported outcomes. This study utilizes the Biofire® FilmArray Panel (RP2.1-EZ) which in previous studies has been shown to be highly effective in diagnosing acute respiratory illnesses.
The prevalence of hepatitis C virus infection (HCV) in patients with inflammatory bowel disease (IBD) ranges from 1-6%. Direct-acting antivirals (DAAs), with cure rates >90%, represent a radical change from interferon-based therapies. The ECCO (European Crohn's and Colitis Organisation) guidelines (Kucharzik T, Ellul P, Greuter T, et al. ECCO Guidelines on the Prevention, Diagnosis, and Management of Infections in Inflammatory Bowel Disease. J Crohn's Colitis. 2021;15(6):879-913) warns about the risk of IBD reactivation due to the effect of DAAs, but HCV management in this situation is uncertain given the lack of evidence. The project is proposed as the largest retrospective multicenter descriptive study carried out to evaluate the use of DAAs for HCV eradication in patients with IBD. The Eneida database (Zabana Y, Panés J, Nos P, et al. The ENEIDA registry (Nationwide study on genetic and environmental determinants of inflammatory bowel disease) by GETECCU: Design, monitoring, and functions. Gastroenterol y Hepatol. 2020;43(9):551-8.) of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) is an adequate registry to identify patients with HCV infection. The serological status of the infection is frequently recorded in the ENEIDA database, and it is generally evaluated at the time of IBD diagnosis, before starting immunosuppressive treatment. The ENEIDA registry has the advantage over large population studies that researchers have access to relevant details of the clinical history, which can respond to the controversies raised. This multicenter retrospective descriptive study will provide useful information to be able to give evidence-based recommendations regarding treatment of HCV in patients with IBD.
