Comparing specific and empirical treatments for eosinophilia

Comparison of Outcome Between Specific Anthelminthic Treatment According to Test Results and Empirical Anthelminthic Treatment in Eosinophilic Patient

Not applicable Interventional Prince of Songkla University · NCT06265870

This study is testing whether specific treatments for high eosinophil counts work better than general treatments when doctors aren't sure about a parasitic infection.

What this trial studies

This study investigates the effectiveness of specific versus empirical anthelminthic treatments in patients with eosinophilia, a condition characterized by elevated eosinophil counts. Participants will undergo various parasite detection methods, including stool microscopy, stool culture, and PCR, to improve the accuracy of diagnosing parasitic infections. The study aims to determine whether empirical treatment can be justified in cases where stool tests are inconclusive or unavailable. By comparing treatment outcomes, the research seeks to provide clearer guidelines for managing eosinophilia in clinical practice.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with an absolute eosinophil count greater than 500 cells per microliter and a white blood cell count less than 10,000 cells per microliter.

Not a fit: Patients with urgent medical conditions, active infections, or those who have received anthelminthic drugs within the last six months may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective and targeted treatments for patients suffering from eosinophilia caused by parasitic infections.

How similar studies have performed: While some studies have shown the efficacy of empirical treatment approaches, this study aims to provide a more structured comparison, making it a novel contribution to the field.
