Sickle cell disease

French national reference center for major sickle cell syndromes and other rare pathologies of the red blood cell and erythropoiesis

drapeau françaisLogo Drepano HEGPOur internal medicine department at the Georges-Pompidou European hospital was certified as an expert center in 2008 in order to improve the management of adult patients with sickle cell disease in western Paris as well as other rare diseases of the red blood cell and erythropoiesis : G6PD deficiency, hereditary spherocytosis, thalassemia, etc.

It allows, among other things, to ensure the transition of the pediatric cohort of the Necker hospital of approximately 600 patients.

Professor Jean-Benoît Arlet has been responsible for the reference center since 2008.

Logo sickle cell center HEGPThe center develops fundamental research projects (at the Imagine laboratory, Necker), but also epidemiological and therapeutic trials on new treatments.

A therapeutic education program is very active to support patients and their families. Expert patients and patient associations are integrated into our team with the aim of constantly improving care.

In case of emergency

The missions of the center are :

  • Caring for sickle cell patients in crisis in the emergency room and in hospitalization.
  • Constantly improve the quality of patient care and their quality of life : reception, speed of care, particularly in emergencies, comprehensive care, listening …
  • Prevent and treat chronic complications of red blood cell diseases (including sickle cell disease) in consultation and day hospitalization.
  • To be a referral center for complex diagnoses of red blood cell diseases (membrane diseases, enzymatic, etc.), complex anemias, and their management.
  • Find innovative ways to improve patient care: therapeutic education (TPE) ; improvement of the hospital setting ; technical solution to improve the perfusion of sickle cell patients, transfusions, compliance with disease-modifying treatments; patient involvement in our meetings, therapeutic and research protocols; involvement of new actors in care (volunteers, patient visitors and hospital schools for example, associations), website, social networks…
  • Training of doctors and paramedics in red blood cell diseases
  • Develop therapeutic education
  • Improving the child-adult transition
  • Raise awareness of these diseases among the general public and health actors
  • Organize the medico-social care of these diseases
  • Research mission: Advance knowledge of the physiopathology of hemoglobinopathies with the aim of rapid therapeutic benefits for patients.
  • Clinical, epidemiological and basic research.
