RESUMEN
El trasplante de células hematopoyéticas (TCH) es la infusión de células progenitoras a fin de restablecer la función medular e inmune en pacientes con enfermedades hematológicas malignas y no malignas adquiridas y genéticas. El impacto del TCH se refleja en las alternativas de tratamiento, mayor difusión de la técnica y mejores opciones al paciente.El procedimiento consiste en la obtención de progenitores hematopoyéticos periféricos, mediante las células CD34+ (2- 2.5 x 106/Kg peso); es un excelente predictor de prendimiento del injerto. El trasplante de donante no relacionado, permite tratamiento a pacientes que carecen de donantes familiares histo-idénticos. Otra variante de TCH es el mini-trasplante, utilizando dosis bajas de quimioterapia e inmunosupresores, produciendo menos complicaciones, pero jerarquizando el efecto “injerto sobre tumor”, que permite la remisión de enfermedades neoplásicas hematológicas y no hematológicas, siendo una alternativa en países en vías de desarrollo, por la posibilidad de disminuir costos y complicaciones.
ABSTRACT
Transplant of Hematopoietic Stem Cells (HSCT) is the infusion of hematopoietic progenitor cells in patients with hematologic malignant, non malignant, acquired and genetic disorders of the bone marrow to reestablish inmune and marrow function. The impact of the HSCT reflects on the choices of treatment, the wide diffusion of the technique and better options to the patient.This procedure consist to obtain the peripheral hematopoietic progenitors; through the CD34+ cells (2–2.5 x 106/Kg) is an excellent predictor of the successful of the engraftment. Transplant from not-related donors allow treatment to patients who lack of haploidentical family donors. Other variable of HSCT is mini-transplant, using low-doses of chemotherapy and inmunosupressors, it produces less complications, and enhances the effect “graft vs tumor”. This allows the remission of the malignant hematologic and non-hematologic diseases. It is becoming a good choice for treatment in developing countries, because decrease costs and complications.
