Examining megakaryocytes in patients with sickle cell disease
Official title: Phenotypic and Transcriptomic Description of Megakaryocytes in Sickle Cell Patient
Run by University Hospital, Toulouse · NCT06887907 · Data updated 2026-11-12
This study looks at how certain blood cells called megakaryocytes behave in people with sickle cell disease to see if they play a role in the complications of the illness.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults over 18 years old with sickle cell disease or S-béta° thalassemia, either in a steady state or experiencing acute complications.
✕Probably not a fit
Patients with other hematologic disorders or those currently receiving immunosuppressive treatments may not benefit from this study.

What this trial studies
This observational study aims to evaluate the role of megakaryocytes, the precursors of platelets, in patients with sickle cell disease (SCD). It focuses on understanding how these cells behave in both steady states and during acute complications such as vaso-occlusive crises and acute chest syndrome. By analyzing the phenotypic and transcriptomic characteristics of megakaryocytes, the study seeks to uncover their involvement in the inflammatory and thrombotic processes associated with SCD. The research is conducted at the University Hospital in Toulouse, where patients will be monitored for their megakaryocyte activity.
Why it matters
Potential benefit: If successful, this study could provide insights into the role of megakaryocytes in sickle cell disease, potentially leading to new therapeutic strategies.
How similar studies have gone: While the role of megakaryocytes in other conditions has been explored, this specific focus on sickle cell disease is relatively novel and untested.
