Twelve of the 18 patients (66.

Obesity is associated with higher overall survival in patients undergoing an outpatient reduced-intensity conditioning hematopoietic stem cell transplant.

Background: The impact of obesity on hematopoietic stem cell transplantation (HSCT) outcome remains controversial and has been considered a relative contraindication for the procedure. We investigated the influence of Body Mass Index (BMI) on the clinical course of adults undergoing an ambulatory HSCT after a non-myeloablative conditioning regimen.

Methods: Adults with hematologic diseases undergoing an autologous or allogeneic HSCT after reduced intensity conditioning (RIC) and supported exclusively with enteral nutrition (EN) were studied.

[Heart transplant in Monterrey, Nuevo León].

Heart failure constantly increases its incidence and prevalence in our society, it was imperative to start a heart transplant program to improve the survival rates of patients with end stages of the disease. Legal issues made impossible to transplant patients out of Mexico City until recent years. Even with an acute hemodynamic and clinic improvement after the transplant, these patients frequently develop complications such as graft rejection or opportunistic infections due to the immunosuppressive schemes increasing the morbidity and mortality of the procedure.

Evaluation of volume and total nucleated cell count as cord blood selection parameters: a receiver operating characteristic curve modeling approach.

The objective of the study was to evaluate the current standard practice of using volume and total nucleated cell (TNC) count for the selection of cord blood (CB) units for cryopreservation and further transplantation. Data on 794 CB units whose CD34+ cell content was determined by flow cytometry were analyzed by using a receiver operating characteristic (ROC) curve model to validate the performance of volume and TNC count for the selection of CB units with grafting purposes. The TNC count was the best parameter to identify CB units having 2 × 10(6) or more CD34+ cells, with an area under the ROC curve of 0.

Treatment of autoimmune cytopenias remains unsatisfactory for patients refractory to first-line management. We evaluated the safety and efficacy of low-dose rituximab plus alemtuzumab in patients with steroid-refractory autoimmune hemolytic anemia and immune thrombocytopenic purpura. Nineteen of 21 included patients were assessable for response (11 with immune thrombocytopenic purpura, 8 with autoimmune hemolytic anemia).

Outpatient reduced-intensity allogeneic stem cell transplantation for patients with refractory or relapsed lymphomas compared with autologous stem cell transplantation using a simplified method.

The effectiveness of reduced-intensity conditioning allogeneic stem cell transplantation (allo- RIC) compared with high-dose chemotherapy followed by autologous stem cell transplantation (auto-SCT) in Hodgkin's disease (HD) and in non-Hodgkin's lymphoma (NHL) patients remains poorly defined. The purpose of the study was to demonstrate the usefulness of auto-SCT or allo-SCT, employing a RIC regimen in refractory or relapsed NHL or HD patients. We analyzed the outcome of 71 patients with advanced disease.

Subcutaneous alemtuzumab plus cyclosporine for the treatment of aplastic anemia.

Aplastic anemia (AA) is most frequently due to autoimmune attack on its own stem cells. Alemtuzumab is a monoclonal antibody which recognizes the CD52 antigen on the surface of T and B cells. It has proved useful in autoimmune diseases, lymphoproliferative conditions, and graft versus host disease.
