Analysis of Growth Differentiation Factor 15 (GDF-15), Mid Regional proAdrenomedullin (MR proADM), and Persepsin Levels in Patient in Acute Coronary Syndrome Patients With Pneumonia, With or Without Influenza Vaccination

May 16, 2026 updated by: Martha Fitri Alextina Tatodi, University of Brawijaya

Analysis of the Relationship Between Growth Differentiation Factor 15 (GDF-15), Mid Regional proAdrenomedullin (MR proADM), and Persepsin Levels in Patients With Acute Coronary Syndrome With Pneumonia and Chronic Obstructive Pulmonary Disease (COPD) With Influenza Vaccination

The goal of this observational study is to analyze the relationship between various biomarkers (GDF-15, MR proADM, and Presepsin) in patients with Acute Coronary Syndrome (ACS) who also have Pneumonia and Chronic Obstructive Pulmonary Disease (COPD) and have received Influenza vaccinations.

The main questions it aims to answer are:

  • Is there a significant correlation between the levels of these specific biomarkers and the clinical outcomes or inflammatory status of these patients?
  • How does Influenza vaccinations relate to the levels of these biomarkers in the context of ACS with comorbid respiratory conditions? Researchers will compare the levels of these biomarkers across the participant group to see if they can serve as indicators of the patients' health status or the impact of the vaccinations.

Participants will:

- Undergo clinical assessment for Acute Coronary Syndrome, Pneumonia, and COPD. Provide medical history regarding Influenza vaccination status. Provide blood samples for the measurement of GDF-15, MR proADM, and Presepsin levels.

Study Overview

Detailed Description

This study focuses on the complex interplay between cardiovascular health and respiratory complications. Acute Coronary Syndrome (ACS) often occurs alongside respiratory conditions like Pneumonia and Chronic Obstructive Pulmonary Disease (COPD), a combination that significantly increases clinical complexity and patient risk. The presence of these comorbidities often triggers a systemic inflammatory response that can be difficult to monitor using standard clinical tools alone.

To better understand this inflammatory landscape, this research evaluates five specific biomarkers:Proteins often associated with heart stress and the body's response to severe infection or inflammation and highly specific markers used to detect and monitor the severity of sepsis and bacterial infections.

A unique aspect of this research is the consideration of Influenza vaccinations. Vaccinations are standard preventative measures for patients with chronic lung and heart diseases, but their influence on the specific biological markers of inflammation during an acute cardiac event remains an area of active investigation.

By measuring these levels, the study seeks to determine if these biomarkers can provide a more "detailed picture" of a patient's condition than traditional methods. This could potentially help clinicians better predict disease progression and understand how prior immunizations might modulate the inflammatory process in patients facing the triple challenge of ACS, pneumonia, and COPD.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Levels of Inflammatory Biomarkers (GDF-15, MR proADM, and Presepsin)
Time Frame: At baseline (admission) and up to 30 days post-vaccination follow-up.
The measurement of serum or plasma concentrations for Growth Differentiation Factor 15, Mid-Regional pro-Adrenomedullin, and Presepsin. This outcome aims to evaluate the systemic inflammatory profile in patients with Acute Coronary Syndrome, Pneumonia, and COPD, and to observe their relationship with vaccination status.
At baseline (admission) and up to 30 days post-vaccination follow-up.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes in Biomarker Levels Post-Vaccination
Time Frame: Measured at 4 weeks post-vaccination.
To evaluate the changes and modulation of GDF-15, MR proADM, and Presepsin levels following Pneumococcal and Influenza vaccinations compared to baseline levels.
Measured at 4 weeks post-vaccination.
