Physiology and Pathologies Linked to Human Splenic Function : Direct and Ex-vivo Perfusion Explorations


Sponsor

Assistance Publique - Hôpitaux de Paris

Enrollment

100 participants

Start Date

Oct 16, 2016

Study Type

OBSERVATIONAL

Conditions

Summary

Human splenic physiology remains poorly understood due to lack of functional exploration. However, through its ability to recognize alterations or modifications in circulating cells and to trigger an innate and adaptive response in response to these anomalies, the spleen plays a central role in several diseases affecting blood cells, directly or indirectly. The analysis of the splenic clearance of abnormal cells during ex-vivo perfusions made it possible to clarify the pathogenesis of malaria and the role of the spleen in the adaptive immune response. The study's investigative team wishes to extend these explorations to other human diseases in which the spleen is involved, and to evaluate the preventive or curative potential of substances that can modify the perception of blood cells by the spleen (e.g. monoclonal antibodies directed against circulating cells, among other options).

Interventions

OTHERSpleen, blood and plasma collection

Adult patients for whom a splenic intervention (spleno-pancreectomy, or a total or partial splenectomy) is planned as part of their care. One or more tubes of venous blood collected for the care will be recovered following the pre- or intra-operative assessment. Immediately following surgery, after careful examination by the pathologist in charge, the whole spleen or spleen fragments will be collected for further analysis. Whenever possible a catheter will be introduced in the splenic artery, the spleen will be flushed/rinsed with 0.1 - 2 L of cold perfusion medium then transferred to the laboratory for ex-vivo perfusion. Before and at the end of the ex-vivo perfusion, splenic blood and spleen fragments will be collected and processed for further analyses.
