Evaluation and Importance of the PD-1/PD-L1 and the IL-10/IL-10R Axis in Malignant and Benign Pleural Effusions - a Pilot Study

• Conditions: Pleural Effusion

• Registration Number: NCT04834830
• Lead Sponsor: University of Vienna

Brief Summary

The aim of this study is to evaluate the concentrations of interleukin-2, interleukin-10, interferon-gamma, PD1+ lymphocytes, and the interleukin-10 receptor expression in malignant and benign effusions.

Detailed Description

In this prospective trial, 80 patients with pleural effusions and indication for thoracocentesis, drainage, indwelling pleural catheter (IPC) management and/or video-assisted thoracoscopic surgery are enrolled. The pleural effusion will be examined for different cytokines, cytokine-receptors, PD1-lymphocytes and CD4+/CD25+/Foxp3+ regulatory T cell.
