ABSTRACT

En el presente trabajo se realizó un estudio retrospectivo de 22 pacientes diagnosticados con síndrome mielodisplásico y a los cuales se les realizó un trasplante de células hemopoyéticas con el fin de evitar el progreso de la enfermedad a un proceso mieloproliferativo. El estudio comprende el período entre octubre de 1988 y diciembre de 2005, y su objetivo es comparar los resultados y evolución de los pacientes con otros centros de trasplante. La sobrevida de nuestros pacientes es similar a la reportada en otros centros.


In the present work a retrospective study of 22 patients with myelodispastic syndrome who underwent a transplant of hemopoyetic cells in order to avoid the progression of the disease in to a myloproliferative process. The study takes into account all the data beginning October 1988 and ending December to 2005, and its objective is to compare the results and the prognosis of these patients against the results of other transplant centers. The super life of our patients is similar to the reports of other centers.

ABSTRACT

Myelodisplastic syndromes (MDS) are clonal hematopoietic disorders, characterized by ineffective hemopoiesis resulting in single or multiple lineages and a high risk of conversion to acute leukemia. Currently, the only established therapy with curative potential for MDS is a hemopoietic stem cell transplant (HSCT). Their results are determined by the type of MDS, age at the BMT and the score according to the international index. In the main studies the disease-free survival (DFS) were 35-43%, relapse 20 to 39% and transplantation-related mortality (TRM) 36-45%. HSCT offers best results in goods prognosis MDS (refractory anemia, refractory anemia with ring sideroblasts) with DFS of 53-72% and 13% of relapse, in contrast with the advanced MDS (refractory anemia with blast in excess (AREB), AREB in transformation and secondary acute leukemia) where the DFS is about ~ 33%, the relapse 23-34% and MRT 37-60%. The HSCT from unrelated donor is an option for patients that do not an HLA-matched related donor, with a ~ 30% of DFS, but with a MRT up to 58%. The HSCT with regimens of low intensity (minitransplants) for aged patients are feasible but their efficacy has not yet been determined.


Los síndromes mielodisplásicos (SMD) constituyen un grupo de enfermedades de las células progenitoras hematopoyéticas (CPH) caracterizadas por hematopoyesis ineficaz y una tendencia elevada a evolucionar a leucemia aguda. Hasta el momento actual el único tratamiento curativo lo representa el trasplante de CPH. Los resultados con esta terapia dependen de la variedad del SMD, de la edad de los pacientes al momento del trasplante y del índice pronóstico internacional. Los resultados de las principales series muestran una supervivencia libre de enfermedad (SLE) de 35-43%, con una recaída de 20 a 39% y una mortalidad asociada al trasplante (MRT) de 36 a 45%. Los mejores resultados se obtienen en SMD de buen pronóstico (anemia refractaria/anemia refractaria con sideroblastos en anillo) con SLE de 53-72% y una frecuencia de recaída de 13%, en contraste con los SMD avanzados (anemia refractaria con exceso de blastos ]AREB], AREB en transformación y leucemia aguda secundaria) en los que la SLE es de ~ 33%, la recaída de 23-34% y la MRT de 37-60%. El trasplante de CPH con donador vivo no relacionado es una opción para los pacientes que carecen de un donador familiar, con SLE de ~ 30% pero con una elevada MRT que llega a ser hasta de 58%. Los trasplantes con acondicionamiento de intensidad reducida (minitrasplantes) son factibles de realizar en pacientes de edad avanzada, aunque su eficacia está aún por determinarse.

ABSTRACT

Adenovirus (AdV) infections are prevalent in bone marrow transplant patients, usually associated with significant morbidity and mortality. Hemorrhagic cystitis (HC) is a major complication mainly attributed to this virus. The authors report a case of AdV HC in a myelodysplastic patient undergoing peripheral blood stem cell transplantation. The diagnosis was confirmed by positive urine AdV antigen using indirect immunofluorescence assay. The patient gradually improved after adequate hydration, supportive treatment and reduced dose of cyclosporine, and was discharged on the ninth day of hospitalization. To the authors' knowledge, this is the first case of AdV HC in stem cell transplantation in Southeast Asia.
