Abstract Objective To analyze the effects of hospital cardiorespiratory physical therapy protocol on the functional capacity and quality of life of patients submitted to hematopoietic stem cell transplantation (HSCT). Methods From January to December 2019, bilateral dynamometry, Manovacuometry and Ventilometry, peak expiratory flow "Peak Flow", 6-min walk test (6MWT), SF-36 Quality of Life Questionnaire and Visual Analog Scale (VAS) were applied in patients who have undergone an allogeneic or autologous hematopoietic stem cell transplantation (HSCT), pre-conditioning (initial evaluation) and pre-discharge (final evaluation). The patients were submitted to an intervention protocol, consisting of aerobic training, muscle strengthening and respiratory muscle training, between the two assessments. Results 29 patients were enrolled in the study and 24 (83%) completed all procedure. Myeloablative and reduced intensity conditioning were performed in 89.6% and 10.4%, respectively; 17 (58%) patients have undergone an autologous HSCT; 10 (35%) identical related allogeneic HSCT, and 2 (7%) haploidentical allogeneic HSCT. The median number of interventions per patient was 3 (1-9). A decreasing in the right and left dynamometry (p ≤ 0.0001 and 0.002, respectively) and, also in the distance covered in the 6MWT (p = 0.004), was observed after HSCT. There was no significant difference in respiratory muscle strength, quality of life and fatigue sensation. Conclusion Cardiorespiratory rehabilitation can preserve functional capacity and quality of life.

ABSTRACT Extraordinary progress has been made over the last decade in the treatment of multiple myeloma with the incorporation of new drugs, particularly proteasome inhibitors, immunomodulators, and monoclonal antibodies. The combined use of innovative drugs, already in the first lines of treatment, has led to an expressive increase in the survival of these patients. However, the approach to relapse remains a great challenge, and the disease continues to be incurable. In this scenario, modern immunotherapy has gained the limelight, especially with its recent use of CAR-T cells in clinical trials, as in the case of multiple myeloma, having the BCMA as the primary target. The results are impactful in the treatment of multiple myeloma patients who have had multiple relapses and are triple- and penta-refractory. In this Consensus, we have brought together a group of experts in multiple myeloma to discuss and forward their recommendations for the future, which we hope is very near, incorporating the CAR-T in our country.

RESUMO A doença do enxerto contra hospedeiro (DECH) é uma das principais complicações do transplante de células-tronco Hematopoéticas, acometendo cerca de 50% a 80% dos pacientes. A DECH aguda e suas manifestações clínicas são discutidas neste artigo, bem como a classificação revisada do NIH para diagnóstico e classificação da DECH crônica. A terapêutica para DECH aguda e crônica é um importante campo de discussão uma vez que não há superioridade comprovada para a maioria das terapêuticas utilizadas após o tratamento primário. Assim, esta revisão pretende ser instrumento de consulta para hematologistas transplantadores que lidam com esta complexa complicação do procedimento.

ABSTRACT 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. Hence, this review is meant to be a useful consultation tool for hematologists dealing with this complex transplantation procedure complication.

INTRODUÇÃO: O transplante de células troncas hematopoiéticas (TCTH) associa-se a mais infecções respiratórias devido a imunossupressão. OBJETIVO: Este trabalho tem o objetivo de verificar a frequência das rinossinusites pós-TCTH, a associação entre a rinossinusite e a doença do enxerto contra hospedeiro (DECH) crônico e o tipo de transplante e o tratamento clinico e o tratamento cirúrgico e a sobrevida. MÉTODO: Estudo retrospectivo em hospital universitário terciário. Foram selecionados 95 pacientes com doença hematológica submetidos a TCTH entre 1996 a 2011. RESULTADOS: A leucemia mieloide crônica foi a doença mais prevalente. O tipo de transplante mais realizado foi o alogênico (85,26%). A frequência de rinossinusite foi de 36%, sem diferença entre os tipos de transplante autólogo e alogênico. A DECH crônica ocorreu em 30% dos pacientes. Os pacientes com DECH tiveram maior frequência e recorrência de rinossinusite, além de mais necessidade de sinusectomia endoscópica e de diminuição da sobrevida global. CONCLUSÃO: Houve maior frequência de rinossinusite no TCTH e DECH. O tipo de transplante não parece predispor a ocorrência da rinossinusite. A DECH parece ser um fator agravante e necessita de tratamento mais rigoroso.

INTRODUCTION: hematopoietic stem cell transplantation (HSCT) is associated with more respiratory infections due to immunosuppression. OBJECTIVE: this study aimed to verify the frequency of rhinosinusitis after HSCT, and the association between rhinosinusitis and chronic graft vs. host disease (GVHD) and type of transplantation, clinical treatment, surgical treatment, and survival. METHODS: this was a retrospective study in a tertiary university hospital. A total of 95 patients with hematological diseases undergoing HSCT between 1996 and 2011 were selected. RESULTS: chronic myeloid leukemia was the most prevalent disease. The type of transplant most often performed was the allogenic type (85.26%). The frequency of rhinosinusitis was 36%, with no difference between the autologous and the allogenic types. Chronic GVHD occurred in 30% of patients. Patients with GVHD had a higher frequency and recurrence of rhinosinusitis, in addition to more frequent need for endoscopic sinusectomy and decreased overall survival. CONCLUSION: there was a higher frequency of rhinosinusitis in HSCT and GVHD. The type of transplant does not appear to predispose to the occurrence of rhinosinusitis. GVHD seems to be an aggravating factor and requires a more stringent treatment.

CONTEXTO E OBJETIVO: A doença do enxerto contra o hospedeiro (DECH) é uma das complicações pós-transplante alogênico de células progenitoras hematopoéticas. Este estudo investigou uma associação entre o antígeno leucocitário humano (HLA) e a ocorrência de DECH aguda e crônica, em pacientes que receberam transplantes de irmãos HLA-idênticos. TIPO DE ESTUDO E LOCAL: Estudo retrospectivo no Centro de Hematologia e Hemoterapia da Universidade Estadual de Campinas (Unicamp). MÉTODOS: Os participantes foram 176 pacientes cujo primeiro transplante foi entre 1997 e 2009. A tipagem HLA foi realizada por sorologia e reação em cadeia da polimerase (PCR) com sequência específica de primers. RESULTADOS: A DECH aguda foi associada positivamente com HLA-A10 (P = 0,0007), HLA-A26 (P = 0,002), B55 (P = 0,001), DRB1*15 (P = 0,0211) e DQB1*05 (P = 0,038), enquanto HLA-B16 (P = 0,0333) foi mais frequente em pacientes sem DECH aguda. A DECH crônica foi associada positivamente com HLA-A9 (P = 0,01) e A23 (P = 0,0292) e, negativamente, com HLA-A2 (P = 0,0031) e B53 (P = 0,0116). HLA-B35 (P = 0,0373), B49 (P = 0,0155) e B55 (P = 0,0024) estavam aumentados em pacientes com DECH aguda grau 3 ou maior, em comparação aos outros pacientes. Em pacientes com DECH crônica extensa, HLA-A9 (P = 0,0004), A24 (P = 0,0059) e A26 (P = 0,0411) estavam aumentados em comparação aos outros pacientes, enquanto HLA-A2 estava diminuído (P = 0,0097). CONCLUSÕES: Este estudo sugere que o HLA pode influenciar a ocorrência de DECH aguda e crônica e a sua gravidade. No entanto, um estudo com melhor desenho e com mais pacientes será necessário para confirmar esses resultados.

CONTEXT AND OBJECTIVE: Graft-versus-host disease (GVHD) is one of the complications following allogenic stem cell transplantation. This study investigated an association between human leukocyte antigen (HLA) and the occurrence of acute and chronic GVHD in patients who had received stem cell transplantations from HLA-identical siblings. DESIGN AND SETTING: Retrospective study at Hematology and Hemotherapy Center, Universidade Estadual de Campinas (Unicamp). METHODS: The participants were 176 patients whose first transplant was between 1997 and 2009. HLA genotyping was performed serologically and using the polymerase chain reaction with specific primer sequence. RESULTS: Acute GVHD was positively associated with HLA-A10 (P = 0.0007), HLA-A26 (P = 0.002), B55 (P = 0.001), DRB1*15 (P = 0.0211) and DQB1*05 (P = 0.038), while HLA-B16 (P = 0.0333) was more frequent in patients without acute GVHD. Chronic GVHD was positively associated with HLA-A9 (P = 0.01) and A23 (P = 0.0292) and negatively with HLA-A2 (P = 0.0031) and B53 (P = 0.0116). HLA-B35 (P = 0.0373), B49 (P = 0.0155) and B55 (P = 0.0024) were higher in patients with acute GVHD grade 3 or above, than in other patients. In patients with extensive chronic GVHD, HLA-A9 (P = 0.0004), A24 (P = 0.0059) and A26 (P = 0.0411) were higher than in other patients, while HLA-A2 was lower (P = 0.0097). CONCLUSION: This study suggests that HLA can influence the incidence and severity of acute and chronic GVHD. However, a study with a better design and more patients will be needed to confirm these results.

OBJECTIVE: To perform a function evaluation of patients before and after hematopoietic stem cell transplantation. METHODS: From November 2008 to November 2010, 29 female (58%) and 21 male patients (42%) with median age of 48 years (range: 24-67) were enrolled in this study. Data collection was performed before and after autologous or allogeneic hematopoietic stem cell transplantation. Evaluation instruments included the 2-minute walking test to evaluate gait performance with assessment of the oxygen saturation, heart rate and Borg Scale before and after the test; grip strength for strength evaluation, Schober Test for spine mobility testing and maximum and adapted activity scores of the Human Activity Profile questionnaire to test functionality in daily activities. RESULTS: Fifty patients were evaluated at baseline; six did not undergo hematopoietic stem cell transplantation (three died, one refused and two were excluded). Thus 44/50 (88% - 21 allogeneic and 23 autologous) transplantations were performed. Only 33 of the 44 patients (75%) performed evaluations after transplantation (nine died and two were excluded). Of the patients who performed both evaluations, significantly lower values were found in the evaluation after transplantation for the 2-minute walking test (p-value = 0.004), grip strength of both right and left hands (p-value = 0.004 and p-value < 0.0001, respectively), the Schober Test, and maximum and adapted activity scores (p-value < 0.0001). The heart rate was higher (p-value = 0.01) before the 2-minute walking test and oxygen saturation was higher (p-value = 0.02) after. CONCLUSION: Statistical differences indicate functional impairment after transplantation showing physical losses in this population.

OBJECTIVE: To evaluate the use of high-dose sequential chemotherapy in a Brazilian population. METHODS: High-dose cyclophosphamide followed by autologous hematopoietic stem cell transplantation is an effective and feasible therapy for refractory/relapsed lymphomas; this regimen has never before been evaluated in a Brazilian population. All patients (106 with high-grade non-Hodgkin lymphoma and 77 with Hodgkin's lymphoma) submitted to this treatment between 1998 and 2006 were analyzed. Chemotherapy consisted of the sequential administration of high-dose cyclophosphamide (4 or 7 g/m²) and granulocyte-colony stimulating factor (300 µg/day), followed by peripheral blood progenitor cell harvesting, administration of etoposide (2g/m²) and methotrexate (8 g/m² only for Hodgkin's lymphoma) and autologous hematopoietic stem cell transplantation. RESULTS: At diagnosis, non-Hodgkin lymphoma patients had a median age of 45 (range: 8-65) years old, 78% had diffuse large B-cell lymphoma and 83% had stage III/IV disease. The Hodgkin's lymphoma patients had a median age of 23 (range: 7-68) years old, 64.9% had the nodular sclerosis subtype and 65% had stage III/IV disease. Nine Hodgkin's lymphoma patients (13%) and 10 (9%) non-Hodgkin lymphoma patients had some kind of cardiac toxicity. The overall survival, disease-free survival and progression-free survival in Hodgkin's lymphoma were 29%, 59% and 26%, respectively. In non-Hodgkin lymphoma, these values were 40%, 49% and 31%, respectively. High-dose cyclophosphamide-related mortality was 10% for Hodgkin's lymphoma and 5% for non-Hodgkin lymphoma patients. High-dose cyclophosphamide dosing had no impact on toxicity or survival for both groups. CONCLUSIONS: Despite a greater prevalence of poor prognostic factors, our results are comparable to the literature. The incidence of secondary neoplasias is noteworthy. Our study suggests that this approach is efficient and feasible, regardless of toxicity-related mortality.

BACKGROUND: The lack of standardization of clinical diagnostic criteria, classification and severity scores of chronic graft-versus-host disease led the National Institutes of Health to propose consensus criteria for the purpose of clinical trials. METHODS: Here we describe a one-day workshop model conducted by the Chronic Graft-versus-Host Disease Brazil-Seattle Consortium Study Group to train investigators interested in participating in multicenter clinical trials in Brazil. Workshop participants included eight transplant physicians, one dermatologist, two dentists, three physical therapists and one psychologist from five institutions. Workshop participants evaluated nine patients with varying degrees of severity of mucocutaneous lesions and other manifestations of the disease followed by a training session to review and discuss the issues encountered with the evaluation and scoring of patients and in the methods used to evaluate grip strength and the 2-minute walk test. RESULTS: Most participants had difficulties in rating the percentage of each type of mucocutaneous lesion and thought 20 minutes was insufficient to evaluate and record the scores of each patient using the National Institutes of Health criteria and other cutaneous assessments. Several specific areas of difficulties encountered by the evaluators were: 1) determining the percentage of erythema in movable and non-movable sclerosis, 2) whether to score all cutaneous findings in a particular area or just the dominant lesion; 3) clarification of the definition of poikiloderma in chronic graft-versus-host disease; 4) discrepant interpretation of the mouth score and 5) clarification on the methodology used for the evaluation of grip strength and the 2-minute walk tests. CONCLUSIONS: Results of this workshop support the need to train investigators participating in clinical trials on chronic graft-versus-host disease.

BACKGROUND: Real time PCR has become the most common technique to monitor BCR-ABL transcript levels of patients treated with kinase inhibitors. The aim of this study was to evaluate BCR-ABL levels of chronic myeloid leukemia patients treated with imatinib in the chronic phase and correlate the response to therapy and event-free survival. METHODS: BCR-ABL levels were measured in peripheral blood cell samples using Real time PCR at diagnosis and then every 3 months after starting therapy with imatinib. Major molecular response was defined as a three-log reduction from the standardized baseline value. Major molecular response values were adjusted to international scale using a conversion factor of 1.19. The results are reported as a BCR-ABL/ABL ratio (%). RESULTS: Hematological, major cytogenetic and complete cytogenetic responses were achieved by 57 (95%), 45 (75%) and 38 (63%) patients, respectively. Twenty-four out of sixty patients achieved a major molecular response (40%) in a median time of 8.5 months. Overall survival and event free survival were higher for patients with (100%) versus patients without (77%) a complete cytogenetic response (p-value = 0.01) at 48 months. Patients with complete cytogenetic response and major molecular response had a higher event free survival compared to patients with complete cytogenetic response but without major molecular response (p-value = 0.007). CONCLUSION: In conclusion, the prognostic impact of achieving complete cytogenetic response and a major molecular response and also the importance of molecular monitoring in the follow-up of chronic myeloid leukemia patients were demonstrated.

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. A total of 34 patients with National Institute of Health chronic graft-versus-host disease were enrolled in the pilot study between June 2006 and May 2009. RESULTS: Of the 34 patients, 26 (76%) met the criteria of overlap syndrome and eight (24%) the classic subcategory. The overall severity of disease was moderate in 21 (62%) and severe in 13 (38%) patients. The median time from transplant to onset of chronic graft-versus-host disease was 5.9 months (Range: 3 - 16 months); the median time for the overlap syndrome subcategory was 5.9 months (Range: 3 - 10 months) and for the classic subcategory, it was 7.3 months (Range: 3 - 16 months). At a median follow up of 16.5 months (Range: 4 - 39 months), overall survival was 75%. CONCLUSIONS: It was feasible to use the National Institute of Health consensus criteria for the diagnosis and scoring of chronic graft-versus-host disease in a Brazilian prospective multicenter study. More importantly, a collaborative hematopoietic cell transplantation network was established in Brazil offering new opportunities for future clinical trials in chronic graft-versus-host disease and in other areas of research involving hematopoietic stem cell transplantation.

O transplante de células-tronco hematopoiéticas (TCTH) causa imunossupressão e predispõe ao desenvolvimento de rinossinusites. A realização de tomografia computadorizada (TC) de seios paranasais pode auxiliar no diagnóstico de rinossinusopatias nestes pacientes, porém a realização em todos estes pacientes é questionável. OBJETIVO: Verificar a necessidade de realizar a TC nos candidatos ao TCTH e relacionar as alterações tomográficas encontradas a rinossinusopatias pós TCTH. MÉTODO: Estudo piloto prospectivo em que as TC de seios paranasais foi executado antes e após o TCTH e avaliado conforme classificação de Lund e Mackay. RESULTADOS: Foram obtidos 77,5% e 61% de TC normais no pré e pós-TCTH, respectivamente. O estádio tomográfico pré-TCTH não se relacionou à ocorrência de rinossinusite após o TCTH. As variações anatômicas encontradas (19,4%) não se relacionaram com a ocorrência de rinossinusite, mas sim com a gravidade da rinossinusite no pós-TCTH. Não houve associação significativa entre estadiamento tomográfico prévio e desenvolvimento de rinossinusite pós-TCTH. CONCLUSÃO: Não há necessidade de realização de tomografia computadorizada de seios paranasais em todos os pacientes previamente ao TCTH; e a variação anatômica não predispõe à rinossinusite nem antes nem após o transplante de medula óssea, apenas pode agravar a evolução da rinossinusite após o TCTH.

Hematopoietic Stem Cell Transplant (HSCT) causes immunosuppression and predisposition to sinusitis. CT scans are complementary exams used in the diagnosis of sinusitis; however, its use in every patient is questionable. AIM: to check the usefulness of ordering a CT scan prior to HSCT and to study the relationship between anatomical variations and sinusitis. METHOD: prospective study in which we performed paranasal CT scans before and after HSCT, using the Lund and Mackay score. RESULTS: 77.5% and 61% of CT scans showed no evidence of sinus disease before and after HSCT. CT staging was not associated with sinusitis after HSCT. Anatomical variations were related to radiographic disease severity, but not to development of sinusitis after HSCT. There was no relation between pre-CT staging and sinusitis after BMT. CONCLUSION: CT scans are not useful for all patients before HSCT. Anatomical variation is not a predictive feature to sinusitis but it can determine its severity.

A leucemia mieloide crônica (LMC) é uma doença clonal da medula óssea caracterizada pela presença do cromossomo Philadelphia (Ph), resultante da translocação entre os cromossomos 9 e 22. O gene híbrido assim formado, BCR-ABL codifica proteínas com atividade de tirosinoquinases que regulam o crescimento celular. A partir da década de 80, o transplante alogênico de células-tronco hematopoéticas (TCTH) se tornou tratamento de escolha para pacientes com idade menor que 55 anos de idade e doador compatível. Não obstante, a partir do advento dos inibidores de tirosinoquinases, drogas de alta eficácia e baixa toxicidade, houve uma mudança no algoritmo de tratamento da LMC. As indicações do TCTH foram restritas em decorrência da mortalidade relacionada a este procedimento e o mesilato de imatinibe tornou-se o novo tratamento de escolha para esta enfermidade. No Brasil e possivelmente em outros países em desenvolvimento, as condições socioeconômicas fazem com que o TCTH ainda seja considerado como primeira linha de tratamento em algumas situações. O TCTH permanece indicado nas doenças (ou neoplasias) mieloproliferativas, como a mielofibrose primária em situações de alto risco e pacientes portadores de policitemia vera ou trombocitose essencial que tenham evoluído para mielofibrose com características de alto risco.

Chronic myeloid leukemia (CML) is a clonal disease of the bone marrow characterized by the presence of Philadelphia chromosome (Ph) which results from translocation between chromosome nine and 22. The hybrid gene, BCR-ABL, encodes proteins with tyrosine kinase activity that regulate cell growth. From the 80´s allogeneic hematopoietic stem cell transplantation (HSCT) has become the treatment of choice for patients younger than 55 years of age and donor. However, from the advent of tyrosine kinase inhibitors, drugs of high efficacy and low toxicity, there was a change in the treatment algorithm of CML. The indications of HSCT have been restricted as a result of mortality related to this procedure and imatinib mesylate has become the new treatment of choice for this disease. In Brazil and possibly in other developing countries, socio-economic conditions make HSCT still feasible as first-line treatment in some situations. The HSCT remains indicated for Ph negative myeloproliferative disorders such as high risk myelofibrosis or patients with polycythemia vera or essential thrombocytosis that have evolved to myelofibrosis with high-risk features.
