INTERVENTIONAL
Conditions
Summary
The investigators developed a protocol to isolate Treg cells from thymic tissue (thyTreg) discarded in pediatric cardiac surgeries. After completing the pre-clinical studies, the investigators have initiated a phase I/II clinical trial to test the safety and efficacy of the adoptive transfer of autologous thyTreg to prevent rejection in heart transplant children. Condition or disease: Heart Transplantation Intervention/treatment: Regulatory T Cell (Treg) Infusion
Eligibility
Inclusion Criteria3
- Patient under two years of age, who meets all the necessary requirements to undergo a heart transplant.
- Patients without contraindication to immunosuppressive drugs.
- Parents and/or guardians must be willing and able to understand the purpose and risks of the study and must sign the informed consent document
Exclusion Criteria10
- Patients with DiGeorge Syndrome, since their thymic function is affected.
- Human immunodeficiency virus positive serology

- Patients with a history of previous malignancy
- Patients who have participated in other intervention studies in the last month.
- Patients who have received induction therapy with Basiliximab or Thymoglobulin.
- Patients who have previously been thymectomized or transplanted.
- Patients who have been diagnosed with severe autoimmune disease (celiac disease, autoimmune hypothyroidism, autoimmune diabetes)
- Patients who will receive an asystole heart
