Consensus of the Brazilian association of hematology, hemotherapy and cellular therapy on patient blood management: History and scenario of patient blood management in the world and in Brazil.

Patient Blood Management (PBM) is a multidimensional approach that seeks to optimize the use of blood and its components in patients. This matter emerged as a response to the need to reduce unnecessary exposure to blood transfusions and their potential risks. In the past, blood transfusion was often overused resulting in complications and high costs. The advent of Patient Blood Management has caused a paradigm shift, highlighting anemia prevention, bleeding control and maximizing the production of blood cells by the organism itself. Patient Blood Management guidelines include the early identification of anemia, strategies to minimize blood loss during surgery, intraoperative blood conservation techniques, preoperative hemoglobin optimization and evidence-based approaches to the rational use of blood transfusions. Aiming to improve clinical outcomes, decrease transfusion-related complications and reduce associated costs, this multidisciplinary approach counts on doctors, nurses, pharmacists and other healthcare professionals. Based on research and clinical evidence, Patient Blood Management continues to evolve thereby promoting safer, more effective patient-centered practices. Its implementation has proven beneficial in various medical contexts thereby contributing to improvements in the quality of care provided to patients. Our goal with this Consensus is to present readers with a broad and diverse view of Patient Blood Management so that they have the building blocks to implement this new technique.

Consensus of the Brazilian association of hematology, hemotherapy and cellular therapy on patient blood management: Definition of Patient Blood Management.

Managing the patient's blood and hematopoietic system is like managing any of the other organs and organ systems during patient care. Specialists control the heart, kidneys, endocrine system, etc. and the patient's blood requires similar clinical treatment. The hematopoietic system and its circulatory products are fundamental for the healthy functioning of the human body. In simple terms, Patient Blood Management (PBM) is an organized, patient-centered approach in which the entire healthcare team coordinates efforts to improve outcomes by managing and preserving the patient's own blood. By reducing dependence on blood transfusions, PBM seeks to improve clinical outcomes, reduce the risks and costs associated with transfusions, and improve the safety and quality of patient care. Essentially, the concept of PBM is about the holistic management and preservation of the patient's own blood in the medical and surgical context.

Consensus of the Brazilian association of hematology, hemotherapy and cellular therapy on patient blood management: Implementation of Patient Blood Management (PBM).

Patient Blood Management (PBM) is a holistic approach to managing blood as a resource of each patient; it is a multimodal strategy that is implemented using a set of techniques that can be applied in individual cases. In fact, the overall result of the implementation of PBM cannot be fully appreciated or explained by simply summing up the effects of the individual strategies and techniques used, since they can only produce the expected ideal result if combined. Implementing a PBM program in healthcare offers several benefits including improved patient safety, better outcomes, cost savings, conservation of resources, evidence-based practice, transfusion alternatives, improved quality of care, compliance with accreditation standards, patient-centered care, and professional education and training.

Chronic graft-versus-host-disease treatment in Brazil: analyses of failure-free survival.

Failure-free survival (FFS), defined as the absence of new systemic treatment, recurrence of original malignancy and mortality not associated with recurrence after allogeneic hematopoietic stem cell transplantation (HCT), is a robust clinical measure to interpret results of initial systemic treatment of chronic graft-versus-host disease (cGVHD). We evaluate FFS after initial treatment of cGVHD in a mixed-race cohort from a resource-constrained country. This retrospective study included 354 consecutive patients after their first HCT between January 2014 and August 2020, who received initial systemic treatment for moderate or severe cGVHD at 13 Brazilian centers. Cox regression models were used to identify risk factors for treatment failure. The overall median follow-up among survivors was 28 months (range 1-71) after initial treatment. FFS was 89% at 6 months, 71% at 1 year and 52% at 2 years. New systemic treatment was the major cause of failure. In multivariable models, prior grades II-IV acute GVHD, a National Institutes of Health severity score of 3 in liver, gastrointestinal tract or lung involvement, and onset of initial treatment of cGVHD within 12 months after transplantation were all associated with an increased risk of treatment failure. Our results could serve as a benchmark for the design of future clinical trials evaluating initial treatment of cGVHD in resource-constrained locations.

Treatment of Acute Lymphoid Leukemia Refractory to Classic First-Line and Rescue Protocols.

Acute Lymphoblastic Leukemia is a very aggressive malignant disorder of lymphoid cells in adults, with recurrence (30 to 60% of the cases) after the initial treatment. Until this moment, there is no gold standard therapy for the treatment of adult patients with acute relapsed/refractory lymphoblastic leukemia. In this case report, we describe two cases of relapsed leukemia: one of lymphocytic leukemia B and one of trilineage leukemia, which presented a satisfactory response to treatment with Bortezomib associated with Vincristine, Dexamethasone, and Bendamustine.

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.

Hematopoietic Stem Cell Transplantation Without the Use of Blood Components by the Patient's Choice: Experience of 2 Brazilian Centers.

Hematopoietic stem cell transplantation (HSCT) has been used to treat many malignant and nonmalignant hematologic conditions; however, the use of HSCT in patients who refuse blood transfusions has rarely been described in the literature, and no data have been published concerning haploidentical HSCT without the use of blood products. The aim of this study is to describe the experience of a Brazilian group in performing 21 HSCTs without the use of blood components in the first 100 days after transplantation, which is the period corresponding to the greatest risk of toxicity for this procedure. We developed 21 HSCTs without transfusion support in 19 patients admitted to 2 Brazilian transplantation centers. The patients were subjected to stem cell mobilization and different conditioning regimens. No mortality related to the procedure occurred among the transplant recipients. The global survival rate after 100 days, which is the period related to the immediate toxicity of HSCT, was 94.7%, and the median duration of follow-up was 980 days, with an overall survival rate of 68.4%. Thus, refusal of blood transfusion is not an absolute contraindication for HSCT. This therapy is feasible in specific situations when the patient clearly expresses a desire to avoid blood transfusions and when favorable clinical conditions are achievable with strict, specialized medical monitoring.

Conidial heads (Fruiting Bodies) as a hallmark for histopathological diagnosis of angioinvasive aspergillosis.

Aspergillosis is a mycosis that afflicts immunocompetent and immunocompromised hosts; among the former it exhibits different clinical pictures, and among the latter the infection renders an invasive form of the disease. The histologic diagnosis of invasive aspergillosis is somewhat challenging mostly because of some morphological similarities between other fungi. However, when present, the conidial heads are pathognomonic of aspergillosis. The authors present the case of a 68-year-old woman who was submitted to autologous hematopoietic stem cell transplantation in the pursuit of multiple myeloma treatment. The post-transplantation period was troublesome with the development of severe neutropenia, human respiratory syncytial virus pneumonia, and disseminated aspergillosis, which was suspected because of a positive serum galactomannan antigen determination, and resulted in a fatal outcome. The autopsy findings showed diffuse alveolar damage associated with angioinvasive pulmonary aspergillosis with numerous hyphae and conidial heads in the lung parenchyma histology. The authors call attention to the aid of autopsy in confirming the diagnosis of this deep mycosis, since only the research of the galactomannan antigen may be insufficient and uncertain due to its specificity and of the possibility of false-positive results.

Liposomal daunorubicin and dexamethasone as a treatment for multiple myeloma: the DD Protocol

CONTEXTO E OBJETIVO: A daunorrubicina lipossomal tem sido usada no tratamento em várias doenças hematológicas malignas, incluindo mieloma múltiplo (MM). O objetivo deste estudo foi avaliar a eficácia, efeitos colaterais e toxicidade da daunorrubicina lipossomal and dexametasona no Protocolo DD. TIPO DE ESTUDO E LOCAL: Estudo prospectivo, realizado nos hospitais Sírio Libanês, São Camilo, Brasil e no Hospital Alemão Oswaldo Cruz. MÉTODOS: 20 pacientes com MM ativo receberam daunoxome (25-30 mg/m²/dia) por três dias consecutivos, mensal, por quatro meses (total de quatro ciclos), e dexametasona, 10 mg a cada seis horas por quatro dias consecutivos (dia 1 - 4, 9 - 12 e 17 - 20), também mensal. RESULTADOS: A mediana entre o diagnóstico e o início do protocolo DD foi de 13 meses. Quinze pacientes receberam alguma quimioterapia anterior ao protocolo DD. Uma redução maior que 50% do pico monoclonal sérico foi observada em seis paciente após o primeiro ciclo do DD (30%), em seis pacientes após o segundo ciclo (30%), em quatro pacientes após o terceiro ciclo (20%) e em quatro pacientes não houve redução (20%). No início do protocolo, 17 pacientes (85%) apresentavam anemia e em 12 destes pacientes (70%) a anemia foi corrigida. Doença progressiva foi observada em três pacientes (15%), um apresentava resposta mínima, quatro pacientes (20%) apresentaram resposta parcial e 12 (60%) apresentaram resposta completa. A toxicidade hematológica foi aceitável.Toxicidade em trato gastrointestinal foi leve, consistindo em náusea (10%) e anorexia (15%), sem episódios de vômito. CONCLUSÃO: Este tratamento apresentou uma baixa toxicidade, uma boa taxa de resposta e pode ser usado previamente ao transplante de medula óssea autogênico.

Liposomal daunorubicin and dexamethasone as a treatment for multiple myeloma--the DD Protocol.

CONTEXT AND OBJECTIVE: Liposomal daunorubicin has been used to treat hematological malignancies, including multiple myeloma (MM). The goal was to evaluate efficacy, side-effects and toxicity of liposomal daunorubicin and dexamethasone ("DD Protocol"). DESIGN AND SETTING: Prospective study at Sírio-Libanês, São Camilo, Brasil and Alemão Oswaldo Cruz hospitals. METHODS: Twenty consecutive patients with active MM received four cycles of liposomal daunorubicin intravenously for two hours (25-30 mg/m(2)/day) on three consecutive days per month, with oral dexamethasone (10 mg every six hours) on four consecutive days three times a month. RESULTS: The male/female ratio was 1:1 and median age 60. Nine patients were stage IIA, ten IIIA and one IIIB. The median from diagnosis to starting DD was 13 months. All patients received four cycles, except one. Fifteen had already received chemotherapy before DD. Responses of > 50% reduction in serum monoclonal paraprotein were observed in six patients after first cycle (30%), six after second (30%) and four after third (20%), while four (20%) did not obtain this. Initially, 17 patients (85%) had anemia: 12 (70%) achieved correction. Progressive disease was observed in three patients (15%), while one had minimal response, four (20%) partial and 12 (60%) complete. Hematological toxicity was acceptable: three patients (15%) had neutrophils < 1,000/mm(3); none had thrombocytopenia. Gastrointestinal toxicity was mild: nausea (10%), anorexia (15%) and no vomiting. CONCLUSIONS: This treatment has mild toxicity and good response rate. It may therefore be feasible before autologous bone marrow transplantation.
