Filter by:This is a comparative, conceptual, randomized clinical study to investigate newly developed over basic Echinacea formulations for the treatment of acute symptoms of respiratory tract infections. 400 adults will be recruited, of which approximately 300 will develop a common cold or a influenza-like infection. Two newly developed and two existing Echinacea formulations (solid/liquid) will be randomly dispensed at inclusion for treatment of maximal 3 infections. Treatment starts at first signs of infection and lasts for a maximum of 10 days or until symptom resolution. Nasopharynx samples will be collected for analysis of common viral respiratory agents throughout treatment. Safety and efficacy variables will be assessed.
Infection with human respiratory syncytial (RS) virus is the most common cause of hospital stay due to pediatric lower respiratory tract infection. An exaggerated immune response contributes to the pathogenesis and small children may have over reactive airways for a long time after an infection. New research has shown that polymorphonuclear leukocytes (PMNs) are stimulated by the virus. Besides fighting the infection they also cause collateral damage to the host. Among other mechanisms PMNs stimulates mucus formation that affects breathing. They also secrete enzymes, toxic proteins and free radicals that may cause harm to lung tissue and airways. The current project strives towards identifying and quantifying inflammatory mediators in sputum, urine and blood of children with severe RS-virus infection. The ultimate aim of the project is to, in detail, describe proteins contributing to the pathogenesis of the disease.
The RAPID trial is a randomized controlled trial that looks at the clinical impact of a rapid respiratory test in a pediatric emergency department. Participants will be randomized to the intervention group - results available to medical providers, or the control group- results not available to medical providers.
This study will analyze gene expression data (HostDx Sepsis test) from blood samples collected from participants with suspected infections. The primary endpoint of the study is to prospectively validate the HostDx Sepsis test for infections. As a secondary endpoint the correlation of participant prognosis and gene expression results in the HostDx Sepsis test will be validated. Participants presenting to the emergency departments of enrolling sites with a suspected infection and 1 vital signs OR suspected sepsis and 2 vital sign changes as stated in the protocol are meeting enrollment criteria
This study will identify infants between the age of 3 and 24 months of age who are experiencing one of their first acute respiratory infections with confirmed wheezing. Infants who are also confirmed to be wheezing and whose caregiver signs consent will be enrolled from a primary care clinic, emergency room or hospital.
This Phase 3 study was intended to assess the relative efficacy of the Quadrivalent VLP Influenza Vaccine during the 2018-2019 influenza season compared to a licensed vaccine in elderly adults 65 years of age and older. One dose of VLP Influenza Vaccine (30 μg/strain) or of Comparator (15 μg/strain) was to be administered to 12,738 participants.
The main objective of this project is to evaluate the agreement between nasopharyngeal and sputum specimens in terms of detection of viral infection in Cystic Fibrosis (CF) participants.This is a 12-month national, multicenter prospective study (7 centers). Inclusions concern CF participants (children or adults) with signs of acute respiratory infection seen in consultation or hospitalized in their CF Research Center. A molecular viral multiplex search is performed on both nasopharyngeal and expectoration collected samples for each included participant. Determination of viral detection agreement between the two CF respiratory samples is then performed.
To evaluate the efficacy and safety of CKD-497
Stepped wedge behavioral intervention clinical trial looking at the impact of an antibiotic stewardship intervention on provider prescribing behavior for acute respiratory infections (ARIs), where the intervention is administered at the emergency department or urgent care center site level, using a cluster randomization process. Thus, every site and every provider are eligible to be exposed to the stewardship intervention, the cluster randomized stepped wedge process simply randomizes when they will be exposed. The overall study hypothesis is that providers will prescribe fewer unnecessary antibiotics to patients with ARIs after the intervention.
Background: Programmed cell death protein 1 (PD-L1) is a protein on the surface of cells. It regulates if a cell can be killed by immune system cells. It is thought to be able to affect the immune system response to diseased cells like those infected with a virus. The molecule M7824 interferes with the activity of PD-L1. It could help the immune system kill cells infected with a virus . Since recurrent respiratory papillomatosis is caused by a virus infection, this molecule could help. Objective: To see if M7824 works in treating recurrent respiratory papillomatosis. Eligibility: Adults ages 18 years or older with recurrent respiratory papillomatosis Design: Participants will be screened with: Medical history Physical exam Blood and pregnancy tests Endoscopy procedure in clinic. A small tube with a camera will look at the inside of the nose, throat, larynx, and upper windpipe. Some participants will also be screened with a chest scan. At the start of the study, participants will: Have a sedated endoscopy procedure where biopsies will be taken. Have blood tests. Have apheresis. Blood will be collected by a tube in an arm vein. A machine will remove white blood cells. The rest of the blood will be returned into an arm vein. Fill out a voice questionnaire. Participants will get the study molecule into a vein over about 1 hour. They will get it every other week for up to 12 weeks. Participants will repeat screening and starting procedures throughout the study. They will also review side effects and any medicine they are taking. When they are done with the study treatment, participants will be evaluated by repeating the study procedures. They may be evaluated periodically until their disease progresses.
