Allogeneic Hematopoietic Cell Transplantation in Elderly Patients in a Latin American Country: Analysis of 11 Year of Data from the Brazilian Registry SBTMO/CIBMTR.

This study analyzed recent changes in the utilization of allogeneic hematopoietic cell transplantation (HCT) for treatment of acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and myeloproliferative diseases (MPDs) and the survival of HCT recipients ≥60 years of age in Brazil. This retrospective registry study included patients who received a first allogeneic HCT from any donor between 2012 and 2023. Of the 6657 patients, 444 (7%) were 60 years of age or older who received grafts from human leukocyte antigen (HLA)-matched related (42%) or unrelated (20%) donors or HLA-haploidentical donors (32%).

Treatment of oral chronic graft-versus-host disease: a retrospective cohort study.

Objective: The aim of this study was to evaluate patients with complete response of oral chronic graft-versus-host disease to immunosuppressive treatment.

Methods: A total of 29 patients submitted to allogeneic hematopoietic stem cell transplantation, with oral chronic graft-versus-host disease, were enrolled in this retrospective study, from September 2012 to February 2018. Patients were treated with combined topical dexamethasone solution and topical tacrolimus ointment, combined topical dexamethasone and topical tacrolimus, systemic immunosuppressive medication, and topical dexamethasone only.

Photobiomodulation Therapy and Dexamethasone in the Management of Oral Acute Graft-Versus-Host Disease: Case Report.

Acute graft-versus-host disease (GVHD) in the oral cavity is a rare complication of hematopoietic stem cell transplantation (HSCT) and treatment has a varying length of time for wound healing. This case report present a 63-year-old female patient with a diagnosis of acute lymphoid leukemia, submitted a related allogeneic HSCT, which after 6 months evolved with oral acute GVHD, presenting odynophagia, dysphagia, and difficulty of hygiene. We started the mouthwash dexamethasone and nystatin oral suspension and five sessions of photobiomodulation therapy (PBMT) (660 nm, 100 mW, 0.

Impact of Anti-CMV IgG Titers and CD34 Count Prior to Hematopoietic Stem Cell Transplantation from Alternative Donors on CMV reactivation.

Cytomegalovirus (CMV) reactivation remains one of the main infectious complications following hematopoietic stem cell transplantation (HSCT). In this study, we explored the role of anti-CMV antibody titers in HSCT from alternative donors and to compare the risk of CMV reactivation between posttransplant cyclophosphamide-based haploidentical HSCT and antithymocyte globulin-based unrelated donor (URD) HSCT. We included 98 CMV-positive patients, 30 undergoing haploidentical HSCT and 68 undergoing URD HSCT.

Brazilian Nutritional Consensus in Hematopoietic Stem Cell Transplantation: Graft- versus -host disease.

The Brazilian Consensus on Nutrition in Hematopoietic Stem Cell Transplantation: Graft- versus -host disease was approved by Sociedade Brasileira de Transplante de Medula Óssea , with the participation of 26 Brazilian hematopoietic stem cell transplantation centers. It describes the main nutritional protocols in cases of Graft- versus -host disease, the main complication of hematopoietic stem cell transplantation.

Impact of Treatment Prior to Allogeneic Transplantation of Hematopoietic Stem Cells in Patients with Myelodysplastic Syndrome: Results of the Latin American Bone Marrow Transplant Registry.

It has been suggested that bridging therapy with intensive chemotherapy and/or hypomethylating agents followed by hematopoietic stem cell transplantation (HSCT) can be valuable in the treatment of patients with myelodysplastic syndromes (MDS). However, the influence of this approach on HSCT outcomes remains poorly defined. Therefore, our objective was to investigate the influence of treatment before HSCT in patients with MDS.

Acute and chronic Graft-versus-host disease after hematopoietic stem cell transplantation.

graft-versus-host disease (GVHD) is one of the main complications of hematopoietic stem cell transplantation, affecting about 50% to 80% of the patients. Acute GVHD and its clinical manifestations are discussed in this article, as well as the new NIH criteria for the diagnosis and classification of chronic GVHD. Therapy for both chronic and acute GVHD is an important field of discussion, as there is no proven superiority for the majority of therapies used after primary treatment has failed.

Randomized double-blind clinical trial comparing clobetasol and dexamethasone for the topical treatment of symptomatic oral chronic graft-versus-host disease.

Patients who undergo allogeneic stem cell transplantation frequently develop an immunologic disease caused by the reactivation of the graft to the host tissues. This disease is called graft-versus-host disease (GVHD) and it is usually a systemic disorder. In a large proportion of cases, oral disorders that are related to a chronic phase of GVHD (cGVHD) occur, and their treatment involves the use of topical immunosuppressive drugs.

Early and late oral features of chronic graft-versus-host disease.

Background: Chronic graft-versus-host disease is a serious complication of allogeneic hematopoietic cell transplantation, and the mouth is one of the affected sites.

Objective: The aim of this study was to evaluate the oral features of this disease after hematopoietic cell transplantation.

Methods: This was a cross-sectional multicenter study that enrolled patients submitted to transplantation.

A multicenter feasibility study of chronic graft-versus-host disease according to the National Institute of Health criteria: efforts to establish a Brazil-Seattle consortium as a platform for future collaboration in clinical trials.

BACKGROUND: New criteria for the diagnosis and classification of chronic graft-versus-host disease were developed in 2005 for the purpose of clinical trials with a consensus sponsored by the National Institute of Health. OBJECTIVES: The aim of this study is to present the results of a multicenter pilot study performed by the Brazil-Seattle chronic graft-versus-host disease consortium to determine the feasibility of using these criteria in five Brazilian centers. METHODS: The study was performed after translation of the consensus criteria into Portuguese and training.

Oral involvement of chronic graft-versus-host disease in hematopoietic stem cell transplant recipients.

Oral manifestations are common in patients who are diagnosed with chronic graft-versus-host-disease (cGVHD). These manifestations can present as oral mucosal lesions, salivary gland dysfunction, or reduction of the mouth opening due to cutaneous sclerosis. Although several studies have reported the prevalence of oral involvement in cGVHD, few have reported details of different types and severity of oral lesions of cGVHD, according to the NIH.

Bone marrow mononuclear cell therapy for patients with cirrhosis: a Phase 1 study.

Background: Bone marrow-derived cell therapy has been investigated in patients with severe liver disease.

Aims: To assess the feasibility, safety and cell kinetics of autologous bone marrow-derived mononuclear cells (BMMCs) infusion in cirrhotic patients.

Methods: BMMCs were isolated from autologous bone marrow and 10% of the cells were labelled with (99m)Tc-SnCl₂.
