Understanding eosinophilic disorders and their mechanisms

Eosinophils and Inflammation, an Expanded Study

Observational Children's Hospital Medical Center, Cincinnati · NCT00267501

This study is trying to understand how certain immune cells behave in people with eosinophilic disorders, like food allergies and gastrointestinal issues, to see how these conditions affect their health.

What this trial studies

This observational study aims to investigate the mechanisms of eosinophil growth, survival, migration, and function in patients with eosinophilic gastrointestinal disease, eosinophilic inflammatory disease, or food allergies. By collecting data and samples, the study seeks to characterize the pathophysiology and clinical manifestations of eosinophilic inflammation in humans. The research will involve patients diagnosed with these conditions as well as normal controls and family members. The findings could provide insights into the severity spectrum of these diseases.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with eosinophilic gastrointestinal disease, eosinophilic inflammatory disease, or food allergies, as well as their family members.

Not a fit: Patients without a diagnosis of eosinophilic disorders or food allergies may not receive any benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a better understanding of eosinophilic disorders, potentially improving diagnosis and treatment options for affected patients.

How similar studies have performed: While there have been studies on eosinophilic disorders, this specific approach to elucidate underlying mechanisms is relatively novel.
