Filter by:Objectives: 1. To compare the immune response of patients with or without sepsis presenting to the ED with a(n) (suspected) infection. 2. To determine immune response aberrations that are associated with an increased risk of developing sepsis in patients presenting to the ED with a(n) (suspected) infection without sepsis. 3. To determine the long term cognitive and physical sequelae of sepsis after admission.
Vapendavir (VPV) is a drug being developed to treat human rhinovirus (RV) infection, one virus responsible for the common cold. Vapendavir prevents the virus from entering cells and making more infectious copies of itself. A study is being planned to investigate VPV in patients with chronic obstructive pulmonary disease (COPD, a lung disease making it difficult to breathe) who develop a rhinoviral infection; however, VPV has not been approved for use in treating any indication (disease) by the FDA or any other global regulatory agency. Therefore, VPV is considered investigational, and the study doctor is conducting this investigational research study. Safety will be monitored throughout the entire study.
Current virus detection methods often take significant time or can be limited in sensitivity, specificity or cost. There is therefore a need for diagnostic methods that are simple to use, sensitive, rapid and inexpensive. This is a proof of concept study to determine whether the OxDx system (a new a rapid pathogen identification technology) is able to detect and differentiate different viruses from nasopharyngeal swabs/aspirate specimens. The data collected will be used to "train" the algorithms to be able to accurately identify respiratory viruses. The accuracy with which the algorithms estimate the test dataset will be monitored at regular intervals during the training dataset collection period. The OxDx system is still under development, which means that it is still "learning". The system needs to see more information so that it can be sufficiently accurate to be used in clinical practice and should become more accurate in identifying these viruses as it sees more and more information from patients. This study will take place at Portsmouth Hospitals University NHS Trust and aims to recruit 1000 patients. To do this, we will recruit both adults and children who either present to the emergency department or are admitted to QAH with a clinical suspicion of a respiratory viral infection. All participants will have a nose and/or throat swab taken as part of their clinical assessment, and we would ask to take a further nasal swab for the purpose of the study. Research sampling will be combined with routine clinical samples where possible to reduce the frequency of testing. We will use most of the information to teach the system how to become more accurate at identifying respiratory viruses. We will keep the remaining information separate and use it to test how accurate the system is. All of the data will be kept securely. Basic information will be collected including age, gender, results of blood tests taken for clinical review, treatment and outcome data. No results from the swabs taken for the purpose of the study will be available to either the participant or the clinical team and the information will have no effect on patient care.
Antibiotics are still most often administered on an empiric fashion, as defined for the general population with dosages only adapted based on weight and renal and/or hepatic functions. As a result, serum concentrations show important interpatient variations with the risk of being subtherapeutic or toxic. Recent studies with temocillin, ceftriaxone, or meropenem confirm this for patients in intensive care units. The aim of the study will be to measure the total and free concentrations of temocillin, ceftriaxone, and meropenem in patients hospitalized in Intensive Care Units for pulmonary infections or another infection for which one of the above mentioned antibiotics is indicated. Patients will be stratified according to the level of their renal function. The antibiotics will be assayed in plasma as well as other accessible fluids in order to assess their pharmacokinetic properties.
