Analyzing Eosinophil Characteristics in COPD Patients

Pilot Study for Evaluation of Eosinophils Phenotype and Activation Status in COPD Patients

IRCCS San Raffaele Roma · NCT04494308

This study is testing how certain immune cells called eosinophils behave in people with COPD to see if their characteristics can help understand the disease better and improve treatment.

What this trial studies

This observational study aims to evaluate the immunophenotype of circulating eosinophils in patients with chronic obstructive pulmonary disease (COPD) by analyzing blood samples from both stable and exacerbated patients. The study will utilize multicolor flow cytometry to assess various membrane molecules and intracellular cytokines associated with eosinophil activation and inflammation. By correlating these findings with the clinical status of the patients, the researchers hope to uncover the role of eosinophils in COPD and their potential impact on disease progression and treatment response.

Who should consider this trial

Good fit: Ideal candidates include COPD patients with a percentage of eosinophils greater than 0%, either experiencing an exacerbation or stable condition.

Not a fit: Patients with a percentage of eosinophils equal to 0% or those with a history of allergic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and management of COPD exacerbations through eosinophil profiling.

How similar studies have performed: While studies have explored eosinophil roles in other conditions, this specific approach in COPD is relatively novel and has not been extensively tested.
