Built from the registry fields of ClinicalTrials.gov. It describes the study, not your situation.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Other illness

  • lung disease: FEV1 and FVC \<50% predicted,
  • Serology or HIV viral load positively
  • severe uncontrolled infection at the time of inclusion or graft

Lab values

  • Liver disease with bilirubin\> 50 .mu.mol / L
  • heart failure defined by NYHA≥3 score ejection fraction \<45% or shortening fraction \<24%

Other

  • Patient with a geno-identical donor
  • Performans status: ECOG\> 1
  • score of PAH NYHA≥2
  • anti HLA alloimmunization against the donor or against red cell antigens of the donor
  • Patients who for family, social or geographical reasons, do not wish to be regularly monitored in consultation
  • pregnant woman (positive beta HCG) or during lactation
  • incapable adult patient, trust, guardianship, or safeguard justice

Who the study is looking for

  • Age: 13 years-40 years
  • Severe Sickle cell with at least one of the following criteria:
    • Stenosing vasculopathy with abnormal MRA despite prolonged transfusion program
    • PAH confirmed by right catheterization with mPAP\> 25mmHg
    • Systolic ejection fraction \<55% and tricuspid regurgitation speed\> 2.5m /s at distance from an acute episode
    • No possibility of blood transfusion or very complicated blood transfusion
    • Report albumin / creatinine\> 30 mg / mmol, confirmed 3 times, away at distance from acute episode and persistent despite hydroxyurea or IEC
    • GFR \<80ml / min /1.73m2 (CKD-Epi without ethnic criterion)
    • Previous history of acute liver sequestration with liver failure
    • Acute chest syndrome or vaso-occlusive crises under hydroxyurea
    • Complications of sickle cell transfusion imposing an exchange program with no possible withdrawal beyond a period of one year
  • Not having geno-identical donor, but a haploidentical major donor (parent, sibling, adult child, or HbAA AS)
  • Having red and understood the information letter and signed the informed consent
  • Patients affiliated to a social security system (Social Security or Universal Medical Coverage)
  • Age\> 18 years and \<60 years
  • Viral serologic economy allows the graft
  • No contraindication for general anesthesia
  • No contraindication the administration of G-CSF (the existence of sickle cell trait is not a contraindication)
  • Lack antigens HLA recognized by the recipient antibody
  • Hemoglobin S \<50%
  • When several donors are compatible: choose according to the ABO recipient: prefer ABO compatibility and major incompatibility and minor incompatibility, and finally major and minor incompatibility.
  • Signature of informed consent
  • Non-inclusion criteria donors: β HCG positive or known pregnancy

Age in the registry: 13 years to 40 years · Sex: All · Does not accept healthy volunteers
