Myocardial Injury & Severe Pneumococcal Pneumonia

Status Terminated

Clinical Trial Summary

Hypothesis: The "novo" cardiovascular events (CVE)in patients with severe community-acquired pneumonia (CAP) are frequent (17%) and could be associated with both direct pneumococcal myocardial invasion, toxin delivery (pneumolysin) or different biomarkers (histones, NETs(neutrophil extracellular traps), IL (Interleukin)-1b,h-Fabp (heart-Fatty acid bindding protein) ).The CVE frequency and its impact on outcome in patients without prior heart disease (CP) has not been studied. Objectives:1) To determine the incidence of myocardian injury (MI) and CVE in patients with CAP without CP evaluated by non-invasive techniques (Echocardiograph and MRI) and biomarkers levels (Tn-I (Troponin I), h-Fabp, NT-proBNP (N-terminal pro-brain natriuretic peptide) histones, NETs, IL 1b); 2) To assess if DMA and CVE are related to the etiology and their impact on outcome , 3) To investigate the presence of myocardial scarring by MRI and its relationship with etiology and MI, and 4) To identify prognostic factors of DMA and CVE to determine level of risk.

Clinical Trial Description

Area: Intensive care unit (ICU) of the participating hospitals. Patients: Forty patients with CAP without heart disease history will be included consecutively (20 patients with pneumococcal CAP and 20 patients with non-pneumococcal CAP).Ten healthy volunteers (controls) are included. Variables: Epidemiological, clinical and hemodynamic variables are recorded. Presence of MI and CVE measured by echocardiography and by biomarkers will be evaluated during the ICU stay. Presence of scarring miocardic by MRI technique will be determined at month 6 since ICU admission. Statistical analysis: Categorical (Fisher's exact test) and continuous variables( Wilconxon and Anova) will be used to determine differences between them. The Pearson correlation, ROC (discriminatory power) and logistic regression analysis(independent association) will be used to determine the association between variables and outcome. A p-value of 0.05 will be considered significant. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
