Experimental studies confirm that the ST2 / IL-33 pathway is involved in the process leading to cardiac transplant rejection in animals. In particular, administration of IL-33 would have a positive effect on pre-clinical cardiac graft survival. No study have looked at the level of ST2 / IL-33 of the donor, with the purpose that it might reflect the condition of the transplanted heart and its initial level of Immune tolerance and maybe predict the risk of subsequent dysfunction.\n\nIn this non-interventional study, several blood samples will be taken on donors before organ procurement and on recipients prior to grafting, on day 7 and at the time of each myocardial biopsy (approximately 16 myocardial biopsies the first year). Serum level of sST2 and IL-33 will then be determined according to the ELISA method on each blood sample.\n\nFifty consecutive couple donors/ recipients will be included in the study. This number of subjects is calculated to detect a doubling of the donor sST2 level between the two recipient groups with 30-day mortality and without mortality (potency: 90%, alpha risk: 0.05, bilateral).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Heart donors and heart recipients', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Consenting recipients\n* Consenting donors to organ/tissue donation for the purpose of scientific research\n\nExclusion Criteria:\n\n* Non consenting recipients\n* Non consenting donors to organ/tissue donation for the purpose of scientific research\n* Multi-organ transplantation'}, 'identificationModule': {'nctId': 'NCT03050892', 'acronym': 'ISIDORE', 'briefTitle': 'Impact of Donor and Recipient ST2 / IL-33 Pathway After Heart Transplantation', 'organization': {'class': 'OTHER', 'fullName': 'Groupe Hospitalier Pitie-Salpetriere'}, 'officialTitle': 'Impact of Donor and Recipient ST2 / IL-33 Pathway on Recipient Survival and Acute Rejection After Heart Transplantation', 'orgStudyIdInfo': {'id': 'CIC-1421-16-01'}}, 'contactsLocationsModule': {'locations': [{'zip': '75013', 'city': 'Paris', 'status': 'RECRUITING', 'country': 'France', 'contacts': [{'name': 'Antonella Galeone, MD, PhD', 'role': 'CONTACT', 'email': 'a.galeone@email.it', 'phone': '0033664841652'}], 'facility': 'Department of Thoracic and Cardiovascular Surgery, Cardiac Institute, Groupe Hospitalier La Pitié Salpêtrière', 'geoPoint': {'lat': 48.85341, 'lon': 2.3488}}], 'centralContacts': [{'name': 'Antonella Galeone, MD, PhD', 'role': 'CONTACT', 'email': 'a.galeone@email.it', 'phone': '0033664841652'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Groupe Hospitalier Pitie-Salpetriere', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'MD, PhD', 'investigatorFullName': 'Antonella Galeone', 'investigatorAffiliation': 'Groupe Hospitalier Pitie-Salpetriere'}}}}
