Resultados del autotrasplante heterotópico de glándula paratiroides en el hiperparatiroidismo multiglandular
2014
INTRODUCCIÓN La técnica del autotrasplante heterotópico de glándula paratiroides más extendida en la actualidad fue descrita por Wells en el 1979. Las indicaciones son las enfermedades que cursan con hiperparatiroidismo multiglandular: HPTP familiar, síndrome de MEN1, síndrome de MEN2A, HPT secundario y HPT terciario. HIPÓTESIS El autotrasplante heterotópico de paratiroides con criopreservación de tejido tras la paratiroidectomía es un tratamiento efectivo para la sustitución de la función paratiroidea en los casos de HPT multiglandular. OBJETIVOS - Analizar nuestra serie de pacientes intervenidos desde 1995 hasta 2012 con una paratiroidectomía total con autotrasplante de paratiroides ( PT+…
Physiological and practical considerations on liver regeneration after liver transplantion
2019
La regeneración hepática ha sido uno de los procesos más estudiados en la medicina al ser el hígado un órgano altamente importante y complejo del organismo, asiento de múltiples enfermedades y expuesto por su ubicación anatómica a los traumatismos. El trasplante hepático se ha convertido en uno de los procedimientos más frecuentes en la trasplantología de órganos, por lo que el conocimiento de los aspectos básicos de esta técnica terapéutica y el estudio de los mecanismos histológicos y fisiológicos vinculados con la regeneración hepática, es fundamental para lograr un resultado satisfactorio. Se realizó un estudio exploratorio de la bibliografía vinculada con el tema, con el objetivo de ex…
Results of heart retransplantation: subanalysis of the Spanish Heart Transplant Registry
2021
Heart retransplantation (ReHT) is controversial in the current era. The aim of this study was to describe and analyze the results of ReHT in Spain. Methods We performed a retrospective cohort analysis from the Spanish Heart Transplant Registry from 1984 to 2018. Data were collected on donors, recipients, surgical procedure characteristics, immunosuppression, and survival. The main outcome was posttransplant all-cause mortality or need for ReHT. We studied differences in survival according to indication for ReHT, the time interval between transplants and era of ReHT. Results A total of 7592 heart transplants (HT) and 173 (2.3%) ReHT were studied (median age, 52.0 and 55.0 years, respectively…
Complicaciones infecciosas en el trasplante de sangre de cordón umbilical de donante no emparentado en adultos con enfermedades hematológicas malignas
2019
El trasplante de sangre de cordón umbilical (TSCU) es una opción terapéutica con potencial curativo para pacientes con enfermedades hematológicas malignas u otras enfermedades con grave afectación de la hematopoyesis que carecen de un donante familiar idéntico y precisan ser trasplantados en un breve plazo. Sin embargo, una de las principales limitaciones del TSCU es la importante morbilidad y mortalidad infecciosa que se observa con este procedimiento. Un detallado conocimiento del perfil clínico y microbiológico de las infecciones que desarrollan los pacientes sometidos a un TSCU es una condición necesaria para tratar de disminuir su impacto en la morbilidad y mortalidad. Así, el análisis…
Antilymphocyte Globulin for Prevention of Chronic Graft-versus-Host Disease.
2016
Clinical Trial, Phase III; Journal Article; Multicenter Study; Randomized Controlled Trial; Research Support, Non-U.S. Gov't; BACKGROUND Chronic graft-versus-host disease (GVHD) is the leading cause of later illness and death after allogeneic hematopoietic stem-cell transplantation. We hypothesized that the inclusion of antihuman T-lymphocyte immune globulin (ATG) in a myeloablative conditioning regimen for patients with acute leukemia would result in a significant reduction in chronic GVHD 2 years after allogeneic peripheral-blood stem-cell transplantation from an HLA-identical sibling. METHODS We conducted a prospective, multicenter, open-label, randomized phase 3 study of ATG as part of …
The Genotype of the Donor for the (GT)n Polymorphism in the Promoter/Enhancer of FOXP3 Is Associated with the Development of Severe Acute GVHD but Do…
2015
The FOXP3 gene encodes for a protein (Foxp3) involved in the development and functional activity of regulatory T cells (CD4+/CD25+/Foxp3+), which exert regulatory and suppressive roles over the immune system. After allogeneic stem cell transplantation, regulatory T cells are known to mitigate graft versus host disease while probably maintaining a graft versus leukemia effect. Short alleles (<=(GT)(15)) for the (GT)(n) polymorphism in the promoter/enhancer of FOXP3 are associated with a higher expression of FOXP3, and hypothetically with an increase of regulatory T cell activity. This polymorphism has been related to the development of auto-or alloimmune conditions including type 1 diabetes …
Umbilical cord blood transplantation from unrelated donors in patients with Philadelphia chromosome-positive acute lymphoblastic leukemia
2014
Clinical Trial; Journal Article; Research Support, Non-U.S. Gov't; There are very few disease-specific studies focusing on outcomes of umbilical cord blood transplantation for Philadelphia chromosome-positive acute lymphoblastic leukemia. We report the outcome of 45 patients with Philadelphia chromosome-positive acute lymphoblastic leukemia who underwent myeloablative single unit cord blood transplantation from unrelated donors within the GETH/GITMO cooperative group. Conditioning regimens were based on combinations of thiotepa, busulfan, cyclophospamide or fludarabine, and antithymocyte globulin. At the time of transplantation, 35 patients (78%) were in first complete remission, four (8%) …
Factores predictivos de desarrollo y evolución de infección activa por citomegalovirus en el transplante alogénico de precursores hematopoyéticos
2021
Citomegalovirus (CMV) es una causa elevada de morbimortalidad en el receptor de trasplante alogénico de precursores hematopoyéticos (alo-TPH). Con la introducción de fármacos específicos frente al virus el riesgo de sufrir enfermedad orgánica por CMV de estos pacientes se ha reducido notablemente; siendo el tratamiento anticipado la estrategia terapéutica más extendida en el manejo de la infección por CMV en el alo-TPH. Sin embargo, esta estrategia es mejorable. En este sentido, nos propusimos analizar una serie de factores que influyen en la monitorización virológica, la cual es inherente a la estrategia de tratamiento anticipado. Dada la elevada variación inter-ensayo e intercentro de las…
Evolution of Functional Exercise Capacity in Lung Transplant Patients With and Without Bronchiolitis Obliterans Syndrome: A Longitudinal Case-Control…
2019
Introduction: Bronchiolitis Obliterans Syndrome (BOS) is a debilitating disease with limited treatment options that threatens both the quality of life and long-term survival of lung transplant (LTx) recipients. This retrospective longitudinal case-control study was performed to compare the long-term functional evolution of LTx recipients with and without BOS. Methods: Twenty-four LTx recipients with BOS (BOS=Cases) and 24 without BOS (NON-BOS=Controls) were selected and individually matched according to age, gender, diagnosis and LTx characteristics. Measurements of 6-minute walking distance (6MWD), symptoms of dyspnea (BORG CR-10 scale), and comprehensive pulmonary function testing were pe…
Near-normal aerobic capacity in long-term survivors after lung transplantation
2021
The clinical course of lung transplantation (LT) is diverse: some patients present chronic lung allograft dysfunction (CLAD) and progressive decline in pulmonary function, but others maintain normal spirometric values and active lives. Objectives The aim of this study was to elucidate whether long-term LT survivors with normal spirometry achieve normal exercise capacity, and to identify predictive factors of exercise capacity. Methods This was a cross-sectional multicentre study, where bilateral LT recipients who survived at least 10 years after LT, with normal spirometry, no diagnosis of CLAD and modified Medical Research Council dyspnoea degree ≤2 underwent cardiopulmonary exercise testin…
