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%) …

Co-administration of human MSC overexpressing HIF-1α increases human CD34+ cell engraftment in vivo

2021

Abstract Background Poor graft function or graft failure after allogeneic stem cell transplantation is an unmet medical need, in which mesenchymal stromal cells (MSC) constitute an attractive potential therapeutic approach. Hypoxia-inducible factor-1α (HIF-1α) overexpression in MSC (HIF-MSC) potentiates the angiogenic and immunomodulatory properties of these cells, so we hypothesized that co-transplantation of MSC-HIF with CD34+ human cord blood cells would also enhance hematopoietic stem cell engraftment and function both in vitro and in vivo. Methods Human MSC were obtained from dental pulp. Lentiviral overexpression of HIF-1α was performed transducing cells with pWPI-green fluorescent pr…

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…

USE OF HERBAL REMEDIES AMONG CANCER AND TRANSPLANT PATIENTS IN THE TOWN OF PALERMO, SICILY

2010

Concomitant use of herbal remedies may lead to toxicity or failure of conventional therapies in different patients. The objectives of this survey were to assess: (1) the prevalence of the use of vegetal remedies by cancer and transplanted patients (2) the level of communication about such use to the physicians (3) whether such use might be associated to adverse reactions or interactions with conventional drugs. The study was carried out on 100 consecutive cancer patients attending the outpatient medical oncology clinic of the University Hospital "P. Giaccone", Palermo and on other 100 transplanted patients who were hospitalized or followed up at ISMETT, Palermo. Another group was composed o…

Urinary collagen cross-links to evaluate hyperparathyroidism in kidney transplant patients

2008

INTRODUCTION AND AIMS: One of most common complication following kidney transplantation is reappearance of hyperparathyroidism (HP) some months after normal serum levels. An early diagnosis represents the best prophylaxis measures to prevent worsening of osteodystrophy and potential damage to the graft and vascular tissue.The aim to our study was to evaluate, beyond the common HP markers, if the urinary cross-links of the collagen PYD (pyridinoline) and DPD (Deoxypyridinoline) are useful markers able to show increasing levels of parathormone. METHODS: We evaluated 50 stable kidney transplanted patients divided into 2 group (A: 38 pts and B: 12 pts) dependent on the type of their immunosuppr…

2015

El trasplante de órgano sólido se ha convertido en una alternativa establecida para el fallo orgánico de muchos pacientes. Los resultados globales del trasplante renal han dado un giro positivo espectacular en el seguimiento a corto y medio plazo, pero para mejorar los resultados a largo plazo quedan por conocer mecanismos de la respuesta inmune, disponer de una monitorización inmunológica precisa y a tiempo real con unos biomarcadores adecuados. La inmunosupresión farmacológica ha supuesto la estrategia principal para prevenir y tratar los episodios de rechazo agudo (RA). El desarrollo de fármacos inmunosupresores cada vez más potentes ha disminuido de forma importante la tasa de rechazo y…
