PROGRESS - prospective observational study on hospitalized community acquired pneumonia

Area of Science:

• Infectious Diseases
• Genetics
• Clinical Research

Background:

• Community acquired pneumonia (CAP) is a frequent cause of hospitalization, with significant mortality rates globally.
• CAP presents challenges in predicting disease severity, progression to sepsis, and patient outcomes.
• Understanding patient heterogeneity is crucial for developing effective treatment strategies.

Purpose of the Study:

• To operationalize disease severity and predict outcomes for hospitalized CAP patients.
• To predict transitions from uncomplicated CAP to severe forms, including sepsis and organ failure.
• To understand patient heterogeneity and develop novel treatment concepts for CAP.

Main Methods:

• A multi-center, observational clinical study (PROGRESS) enrolling over 1600 patients with CAP and low co-morbidities.
• Close monitoring of disease course and therapy with daily assessments and long-term follow-up.
• Collection of daily blood samples for molecular-genetic characterization, stored with clinical data in a central biobank and database.

Main Results:

• Established a comprehensive database of high-quality clinical and molecular data for CAP research.
• Facilitated in-depth molecular characterization to discover disease mechanisms and identify biomarkers.
• Focused on younger patients with low co-morbidities to better understand host biology in CAP.

Conclusions:

• The PROGRESS study provides a valuable resource for investigating CAP.
• Molecular characterization aids in discovering disease mechanisms and developing diagnostic/predictive biomarkers.
• Further validation in diverse cohorts is needed to assess the clinical utility of findings.
