Evaluating the effects of autologous blood transfusion in healthy volunteers

Modification of Biological Parameters After Autologous Blood Transfusion of a Small Volume of Packed Red Blood Cells (200 Ml) in Healthy Volunteers

Not applicable Interventional Assistance Publique - Hôpitaux de Paris · NCT03889834

This study is testing how different types of autologous blood transfusions affect healthy volunteers to see if there are any changes that could help spot doping in sports.

What this trial studies

This study aims to assess the biological changes that occur after autologous blood transfusion in healthy volunteers. It involves a randomized, double-blinded design where participants are divided into three groups: those receiving refrigerated blood, those receiving frozen blood, and a control group with no transfusion. Blood samples will be collected at various points to analyze morphological and biochemical parameters of red blood cells and associated microparticles. The ultimate goal is to identify potential markers of autologous blood transfusion that could indicate doping practices in sports.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy male volunteers aged 18 to 35 who regularly engage in sports activities.

Not a fit: Patients with medical conditions that contraindicate blood drawing or sports practice will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to the development of reliable markers for detecting autologous blood transfusion, enhancing anti-doping efforts in sports.

How similar studies have performed: While the approach of identifying blood markers for doping is established, this specific methodology of assessing autologous transfusion effects in healthy volunteers is relatively novel.
