Filter by:A Phase 1b/2a, Double-blind, Placebo-controlled, Dose-escalation Study to Evaluate the Safety, Pharmacokinetics, and Pharmacodynamics of Recombinant Human Plasma gelsolin (rhu-pGSN) Added to Standard of Care in Subjects Hospitalized for Acute Community-acquired Pneumonia (CAP)
To assess the effectiveness of a management strategy combining a broad panel respiratory mPCR and an algorithm of early antibiotic de-escalation and discontinuation based on both the mPCR results and the procalcitonin (intervention) in severe CAP, as compared to a conventional strategy (control). A multicentre, parallel-group, open-label, randomized controlled trial. The primary assessment criterion est the number of antibiotic-free days at 28 days
Community-acquired pneumonia (CAP) is frequently suspected in the Emergency Department (ED). However, usual diagnosis procedure based on clinical features and chest X-Ray has rather bad performances. A recent study on CT performance in suspected CAP found that 58% of classifications were modified by CT when compared with usual procedure. However, extended CT usage in CAP diagnosis is associated with many limitations : availability in a majority of ED, delay, cost and irradiation, in particular In young patients. Lung Ultrasound (LUS) has good performances in CAP diagnosis even when compared with CT. It is a rapid, inexpensive, radiation-free tool available in a majority of ED. It is performed at the patient's bedside with immediate results. The learning curve allows Emergency Physicians (EP) to perform this exam after a relative brief training. The Investigators aim to investigate LUS performances in clinically suspected CAP authentication , and assesses specific diagnostic contributions and impact on antibiotic prescriptions .
Statement of the problem: Overprescription of antibiotics raises important public health issues because of the emergence of multiresistant bacteria by selection pressure. The results of the observational prospective study entitled "CAPA" on the description of 886 suspected cases of acute community-acquired pneumonia (CAP) treated in general practices in France confirm that, whatever the etiologic hypothesis and the results of the chest X-ray, these patients routinely receive antibiotics. Therefore, it is important to be able to distinguish cases of pneumococcal CAP in which early antibiotic treatment is justified from those cases for which another strategy could be considered. Primary objective: To identify the clinical, biological and radiological characteristics of patients with pneumococcal CAP amongst all patients with CAP radiologically confirmed, in general practice in France. Design : Prospective cross-sectional descriptive study. Inclusion criteria. Adults older than 18 showing clinical signs suggestive of CAP (at least one sign of infection and at least one pulmonary sign) and able to realize chest X ray within 6 hours after prescription. Patient follow-up procedures. Patients will be treated by standard of care according to French recommendations. After observing clinical signs suggestive of CAP, the physician prescribes a chest X-ray. Then, protocol-specific examinations (blood sample, oropharyngeal sample for multiplex polymerase chain reaction (PCR), sputum sample testing (induced expectoration if possible), urinary sample) will be performed on all out patients. Patients will be contacted again on day 28 to increase diagnostic certainty. For patients with clinical signs of CAP and hospitalized, the investigator will ask their consent to retrieve the hospital report, on or before day 28 and to be contacted on day 90.
The purpose of this study is to evaluate the added diagnostic value of a quantitative polymerase chain reaction targeting the lytA gene in detecting pneumococci in patients with community-acquired pneumonia.
In patients with clinical symptoms of respiratory infection, rapid identification of cases requiring antibiotic therapy is crucial to avoid development of multiple resistant bacteria. Identification of local acute-phase reactants can help assess the host's response to bacterial infection at the injury site. Here, the investigators developed an affordable, stable, feasible, and accurate diagnostic tool based on a locally produced protein with specific binding affinity to polysaccharides. The investigators further evaluated the ability of the novel test strip to rule out pneumonia.
The overall aim of the TREND study is to improve the differential diagnosis of bacterial and viral etiology in children below 5 years of age with clinical community acquired pneumonia. Specific objectives: - To assess the diagnostic accuracy of MxA for viral CAP (sub-study I) - To study etiologies in children with CAP (sub-study II) - To evaluate sensitivity and specificity for MariPOC® Respi test versus PCR for detection of respiratory viruses (sub-study III) - To assess sensitivity and specificity for a novel RPA-based point-of-care test versus PCR for detection of respiratory viruses (sub-study IV) - To assess long-term complications in children with CAP (sub-study V The study takes place at Sachs' Children and Youth hospital in Stockholm.
This preliminary study investigates in patients with possible clinical diagnosis of pneumonia, clues and biomarker assessed at Emergency Department (ED) triage, potentially predicting detection of lung consolidation by Thoracic-ultrasound (TUS) and/or by Chest-X-Rays. Cough and high admission CRP levels will be defined according to the cutoff defined by ROC analysis, will be challenged if independently associated with TUS lung consolidation detection High level of the chosen biomarker, and any of the considered symptoms, in otherwise not extremely critical patients (CURB65≤3), should prompt to immediate confirm by TUS, during the physical examination. This may limit the need of further radiological investigations allowing targeted workup.
Severe community acquired pneumonia is common and associated with high mortality. Conventional microbiological diagnostics identify pathogens in approximately half of cases, which is inadequate for both clinical and epidemiological purposes. This study applies next-generation sequencing based metagenomic techniques to patients with extremely severe community acquired pneumonia, to investigate the microbiome of severe community acquired pneumonia and evaluate metagenomic approaches as diagnostic tools.
Prospective, open-label, parallel-group, 52-week trial comparing varenicline in combination with behavioral support with one session of behavioral support alone. Eligible patients were smokers hospitalized due to a) acute exacerbation of chronic obstructive pulmonary disease (COPD), or b) bronchial asthma attack, or c) community-acquired pneumonia (CAP). The primary outcome was the success rate (%) at week 52. Secondary outcomes were quality of life (QoL) alterations on the domains of the 36-Item Short Form Health Survey (SF36) and investigation of possible predictors for smoking abstinence.
