Active clinical trials for "Pneumonia"

The study objective is to assess Efficacy and safety of Reparixin treatment as compared to placebo (both on top of standard treatment) in adult patients with severe COVID-19 pneumonia.

A Phase 3 comparative study to determine the efficacy, safety and tolerability of Aztreonam-Avibactam (ATM-AVI) ± Metronidazole (MTZ) versus Meropenem (MER) ± Colistin (COL) for the treatment of serious infections due to Gram negative bacteria.

Pneumonia is the most frequent infection in critically ill patients and remains a significant challenge to intensivists world-wide due to persisting high mortality and morbidity. Compelling evidence suggests that appropriate antibiotic therapy remains the most important intervention to improve patients' outcome, including the administration of a suitable molecule at an optimized dosage regimen. A vast array of pathophysiological changes can occur in critically ill patients that can complicate antibiotic dosing. Knowledge of the pharmacokinetic and pharmacodynamic properties of the antibiotics used for the management of critically ill patients is essential for selecting the antibiotic dosing regimens, which will optimize patient outcomes. Changes in volume of distribution (Vd) and clearance (CL) of antibiotics have been noted in these patients, which may affect the antibiotic concentration at the target site. It follows that the pharmacodynamic parameters that determine antibiotic efficacy, which can vary between antibiotic classes, may also be affected. Optimization of these parameters is necessary to maximize the rate of response through patient recovery and minimized antibiotic resistance. In a multicenter observational study in critically ill patients with normal plasma renal indices at admission, about 65% of patients manifested augmented creatinine clearance on at least one occasion in the first seven study days. Augmented creatinine clearance may significantly impact drug pharmacokinetics for a variety of renally eliminated pharmaceuticals (such as low-molecular weight heparins, aminoglycosides, glycopeptides, and β-lactams), leading to subtherapeutic concentrations and potentially adverse clinical outcomes. Currently little data exist that describe the consequences of augmented creatinine clearance on antibiotics PK. Ceftaroline (600 mg bid) is a cephalosporin with expanded gram-positive activity, including MRSA and penicillin-resistant streptococcus, which was approved by the US Food and Drug Administration (FDA) on October 29, 2010 for the treatment of acute bacterial SSSIs and community-acquired bacterial pneumonia. Ceftaroline showed also good activity against some of the common gram-negative respiratory pathogens (eg, Haemophilus influenzae, Moraxella catarrhalis, Neisseria meningitidis, and Pasteurella multocida). However, it does not display clinically relevant activity against Pseudomonas aeruginosa, Stenotrophomonas maltophilia, or Acinetobacter baumannii. Ceftaroline also lacks activity against gram-negative organisms with extended-spectrum β-lactamases. Importantly, because ceftaroline appears to induce AmpC β-lactamases despite MIC values in susceptible range, ittheoretically should be avoided in gram-negative bacteria known to harbor inducible AmpC β-lactamases (eg, Serratia, Proteus, Citrobacter, Morganella, Enterobacter, Providencia, and P. aeruginosa). In patients, ceftaroline is given as a prodrug, ceftaroline fosamil. After intravenous administration, the prodrug is rapidly transformed by plasma phosphatase enzymes to its bioactive metabolite. The pharmacokinetics of ceftaroline has been evaluated in single and multiple dose studies in healthy volunteers, in subjects with various degrees of renal impairment and in healthy elderly subjects. The volume of distribution is equal to 20.3 L, which corresponds to extracellular fluid volume. The protein binding is low (20%). The main route of elimination is via renal excretion, with a clearance estimated to160 mL/min close to the creatinine clearance. The elimination half-live is 2.6 h in adults with normal renal function. Unfortunately, no PK study has been performed in infected critically ill patients with augmented creatinine clearance. The best PK-PD index predicting drug efficacy is %Time>CMI. A bacteriostatic effect is achieved when free drug concentrations exceed the MIC for 30 to 40% of the dose administration interval (30 to 40%T>MIC). Near maximum organism kill is achieved at 50 to 60%T>MIC (30%T>MIC for Staphylococcus aureus). This project aims to characterize ceftaroline PK in patients with early-onset pneumonia and augmented creatinine clearance. The choice of ceftaroline is justified by its spectrum suitable for micro-organisms commonly encountered in early onset pneumonia, including methicillin-resistant Staphylococcus aureus. Secondary main objective is to predict the probably of reaching PK-PD targets using Monte Carlo simulations under various scenario in order to identify optimal ceftaroline administration schemes in critical care patients with various degrees of renal impairment.

AR-301 is being evaluated as an adjunctive treatment of ventilator-associated pneumonia (VAP) due to Staphylococcus aureus (S. aureus) in combination with standard of care (SOC) antibiotic therapy in patients with confirmed S. aureus infection.

Rationale: Uncertainty in the clinical and etiological diagnosis of community-acquired pneumonia (CAP) often leads to incorrect treatment and unnecessary use of broad-spectrum antibiotics. Establishing the clinical diagnosis of CAP is hampered by the suboptimal sensitivity of chest radiograph to detect pulmonary infiltrates (~70%). Establishing the etiological diagnosis is also hampered, mainly because of the inevitable diagnostic delays and low sensitivity of routine microbiological tests. There are currently no recommendations for low-dose chest computed tomography (low-dose CT) or viral and bacterial point-of-care multiplex polymerase chain reaction (PoC-PCR) in the diagnostic work-up of CAP patients, because the data supporting such an approach are lacking. Objective: The aim of this study is to determine the added value of low-dose CT and PoC-PCR in the diagnostic workup of patients with CAP hospitalised to non-intensive care unit (ICU) wards in minimizing selective antibiotic pressure while maintaining patient safety. Study design: Cluster-randomised controlled trial with historical control period. Study population: Adult patients (>=18 years old) with a clinical diagnosis of CAP requiring hospitalisation to a non-ICU ward. Intervention: Intervention arm 1: availability of PoC-PCR during the ER visit; intervention arm 2: performing low-dose CT from the ER or at least within 24 hours; control arm: standard care. Main study parameters/endpoints: The primary effectiveness outcome is days of therapy of broad-spectrum antibiotics. The primary safety outcome, on which the sample size is calculated, is 90-day all-cause mortality. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There are no risks associated with performing the PoC-PCR and the radiation of the low-dose CT is of negligible risk. Nasopharyngeal swab collection causes a temporary unpleasant sensation. The low-dose CT can reveal unexpected findings which may require additional diagnostic procedures, for which the treating physician will use state-of-the-art guidelines. Treatment recommendations to de-escalate or stop antibiotic treatment may be beneficial for the individual patient by minimising exposure to antibiotics and improve targeted use of antibiotics. Final decisions are always made by the treating physician taking into account all clinical information.

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)

This is a multi-center, randomized, double-blind, placebo-controlled, superiority clinical trial will test the effectiveness of short (5-day) vs.standard (10-day) course therapy in children who are diagnosed with CAP and initially treated in outpatient clinics, urgent care facilities, and emergency departments. Primary objective is to compare the composite overall outcome (Desirability of Outcome Ranking, DOOR) among children 6-71 months of age with CAP assigned to a strategy of short course (5 days) vs standard course (10 days) outpatient beta-lactam therapy at Outcome Assessment Visit #1 (Study Day 8 +/- 2 days)

Community-acquired pneumonia is acquired outside the hospital. Postural drainage is the positioning of a patient with an involved lung segment such that gravity has a maximal effect of facilitating the drainage of Broncho-pulmonary secretions from the tracheobronchial tree. It is based on the concept of gravity-assisted mobilization of secretions and transports it for removal. The objective of the study to find the effect of postural drainage and positive expiratory pressure techniques (PEP) to improve the air way clearance and breathing in pneumonia patients. This study will be a RCT and will be conducted in Services Hospital. The study will be completed within the duration of six month. Consecutive sampling study technique will be used to collect the data. The sample size of 46 patients will be taken. Patients will be divided into two groups. (Group A will be treated with postural drainage and Group B will be treated with positive expiratory pressure technique). Outcome measure will be taken on Pulse oximeter, incentive spirometer and chest X- Ray. A regular follow up visits to department and a final assessment was made at the end of four week. Data will be analyzed using SPSS software version 25. After assessing normality of data by Shapiro- Wilk test, it will be decided either parametric or non-parametric test will be use within a group or between two groups.

The current work aims to: Measure the levels of Neutrophil CD64 Receptor, Monocyte Human Leukocyte Antigen-DR (mHLA-DR), and Triggering Receptor Expressed on Myeloid Cells 1 (TREM-1) in children suffering from pneumonia. Compare these levels to their levels in healthy control children. Analyze the cut-off point, sensitivity, specificity, and area under the ROC curve of these biomarkers to test their abilities to early differentiate children with pneumonia from healthy control children. Conclude or reject their possible use as diagnostic and/or prognostic markers in pediatric pneumonia.
