RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Oral surgical procedures are a great challenge in cancer patients, especially those with pancytopenia, given the risk of both hemorrhage and opportunistic infection. Thus, we report herein a case of a patient with refractory acute myeloid leukemia, severe pancytopenia, and some episodes of febrile neutropenia, who presented asymptomatic, bilateral lesions on the tongue, requiring excisional biopsy. Considering the high risk of bleeding, surgical intervention was proposed with a high-power laser (HPL) at the bedside. There was no considerable bleeding and stitches were not needed. Within 48 h postoperatively, the patient reported neither pain nor further bleeding and her tongue presented normal function. The patient was under a follow-up period of about 8 months, with no lesion relapse. The HPL seems to be of great value for preventing excessive bleeding and late infection in patients with pancytopenia submitted to minor oral surgeries.

RESUMO

Background: Patients with hematological disease are 15 times more likely to develop sepsis than the general population. The patient with hematological disease and, mainly, those undergoing hematopoietic stem cell transplantation (HSCT), develop a severe secondary humoral immunodeficiency, with low serum levels of IgM, which may take more than a year to be restored. Materials and Methods: This is a retrospective, controlled and observational study that analyzed 51 patients with underlying hematological disease, who were diagnosed with sepsis or septic shock during the study period, to evaluate whether IgM-rich Ig replacement decreases the 30-day mortality. Results: Of the 51 patients, 35 patients received IgM-rich immunoglobulin (group A) and 16 (31%) received conventional therapy. Eleven (69%) patients in the control group were alive after 30 days compared to 11 (34%) patients in the intervention group, p= 0.013. Conclusion: There are no apparent benefits in the use of IgM-rich immunoglobulin in septic patients with hematological disease.

RESUMO

The relationship between cytomegalovirus (CMV), a severe complication in immunocompromised patients, and graft-versus-host disease (GVHD) has already been reported but remains without complete elucidation, especially concerning oral lesions. Considering that antimicrobial photodynamic therapy (aPDT) has an antimicrobial effect and photobiomodulation therapy (PBM) provides analgesia and modulation of inflammatory processes, the present study aimed to report a clinical case in which oral CMV reactivation following acute GVHD was treated by a combination of aPDT and PBMT concomitantly with conventional drug treatment. Intense and uninterrupted oral pain and consequent impairment of the patient's oral functions were present due to ulcerated lesions in the tongue, soft palate, and labial mucosa. After 72 hours from the first laser session, a marked decrease in the severity of the lesions and pain relief was observed. All oral lesions were repaired within 30 days. Based on this case report, when used concomitantly with conventional drug treatment, the combination of aPDT and PBMT seems to play a crucial role in treating CMV associated with GVHD.

RESUMO

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.

RESUMO

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. We retrospectively analyzed data from the Latin American registry of 258 patients from 17 Latin American centers who underwent HSCT from 1988 to 2019. Our data showed that there was pre-HSCT. We detected no significant difference regarding the impact on overall survival of treated and untreated patients before HSCT. Despite these data, the type of previous treatment among treated patients showed a significant difference in overall survival. Treatment with hypomethylating agents together with pre-HSCT chemotherapy seems to result in better survival of the studied population. These data correspond to the first results obtained through cooperative work between various centers in Latin America comparing the different approaches to patients and reflecting their reality and challenges. Therefore, the selection of pretransplant bridge therapy should be analyzed and focus given primarily to those approaches that result in better survival of patients with MDS.

RESUMO

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.

RESUMO

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.
