ABSTRACT

Objetivo: evaluar y correlacionar la calidad de vida general y la función cognitiva de pacientes adultos con cáncer hematológico sometidos al trasplante de células madre hematopoyéticas autólogo y alogénico hasta tres años luego del tratamiento. Materiales y método: estudio longitudinal, observacional y analítico con 55 pacientes, en un hospital de referencia en Latinoamérica, de septiembre del 2013 a febrero del 2019, con el instrumento Quality of Life Questionnarie-Core 30, analizado con las pruebas coeficiente de correlación de Spearman y el Generalized Linear Mixed Model. Resultados: la calidad de vida general en el trasplante autólogo y alogénico presentaron descenso en la fase de pancitopenia (59,3 y 55,3, respectivamente). Hubo disfunción cognitiva en el grupo autólogo posteriormente al trasplante dos años (61,90) y el grupo alogénico (74), en la pancitopenia. En el grupo autólogo, se observa correlación positiva (0,76) y significativa (p < 0,04) entre el dominio cognitivo y la calidad de vida en el post-trasplante dos años. En el alogénico, hubo correlación positiva (0,55) y significativa (p < 0,00) desde el post-trasplante 180 días. Conclusiones: la calidad de vida y la función cognitiva presentan compromiso y hay correlación luego del trasplante de células madre hematopoyéticas para ambos grupos, autólogo y alogénico.


Objective: To assess and correlate overall quality of life and the cognitive function of adult patients with hematologic cancer subjected to autologous and allogeneic hematopoietic stem cell transplantations up to three years after treatment. Materials and method: A longitudinal, observational, and analytical study was conducted with 55 patients in a reference hospital in Latin America, from September 2013 to February 2019, with the Quality of Life Questionnaire-Core 30, analyzed with the Spearman's correlation coefficient and Generalized Linear Mixed Model tests. Results: Overall quality of life in autologous and allogeneic transplantations presented a decline in the pancytopenia phase (59.3 and 55.3, respectively). There was impairment of the cognitive function in the autologous group in post-transplantation after two years (61.90) and, in the allogeneic group (74), in pancytopenia. In the autologous group, a positive (0.76) and significant (p < 0.04) correlation is observed between the cognitive domain and quality of life in post-transplantation after two years. In the allogeneic group, there was a positive (0.55) and significant (p < 0.00) correlation from 180 days after transplantation. Conclusions: Quality of life and the cognitive function present impairment and there is a correlation after the hematopoietic stem cell transplantation for both groups: autologous and allogeneic.

ABSTRACT

A utilização do relaxamento com imagem guiada pode trazer benefícios ao paciente submetido ao transplante de células-tronco hematopoéticas ao possibilitar alívio de sintomas físicos e emocionais, influenciando na qualidade de vida relacionada à saúde. O objetivo deste estudo foi analisar as alterações nos domínios da qualidade de vida relacionada à saúde e variáveis fisiológicas de pacientes internados submetidos ao transplante de células-tronco hematopoéticas, que receberam a técnica de relaxamento com imagem guiada por realidade virtual. Trata-se de estudo quase-experimental, longitudinal, realizado em um Serviço de Transplante de Medula Óssea de hospital público no sul do Brasil. De outubro de 2019 a outubro de 2020, foram incluídos 42 participantes adultos submetidos ao transplante de células-tronco hematopoéticas, sendo alocados 35 no grupo intervenção e 7 no grupo controle em uma razão 5:1. Para o primeiro, foi utilizado como intervenção o relaxamento com imagem guiada por realidade virtual. Foram aferidas pressão arterial, frequências cardíaca e respiratória, saturação de oxigênio, temperatura e dor imediatamente antes e após a intervenção. A coleta de dados ocorreu em quatro momentos: internação (T1), dia zero (T2), fase de neutropenia (T3) e pré-alta hospitalar (T4). Para ambos os grupos foram aplicados questionários sociodemográfico e clínico e Functional Assessment of Cancer Therapy-Bone Marrow Transplantation, Functional Assessment of Chronic Illness Therapy-Fatigue e Functional Assessment of Cancer Therapy-Neutropenia para avaliação da qualidade de vida relacionada à saúde, foram avaliados também valores de hemograma e leucograma. Os resultados mostraram média geral de idade de 37,8 anos e faixa de renda de 1 a 3 salários mínimos, 21 (70%) participantes do grupo intervenção e cinco (71,43%) no controle. O transplante alogênico foi predominante, 28 (80%) no grupo intervenção e cinco (71,43%) no controle. As leucemias foram o diagnóstico mais frequente em ambos os grupos, 13 (34,14%) no grupo intervenção e três (42,86%) no controle. Não houve diferenças entre os grupos nas avaliações de qualidade de vida relacionada à saúde, contudo foi encontrada diferença significativa entre as etapas e correlação positiva significativa entre as variáveis qualidade de vida geral, preocupações adicionais, fadiga e neutropenia em todas as etapas para o grupo intervenção. Foram encontradas diferenças significativas entre as médias das aferições antes e depois em frequência cardíaca e respiratória, temperatura, saturação de oxigênio e pressão arterial no grupo intervenção. Houve semelhança no comportamento dos valores de hemograma, leucograma e no tempo para pega medular em ambos os grupos. A intervenção é, em geral, bem aceita e não foram encontradas evidências de eventos adversos relacionados à sua aplicação. Apesar de não ter sido verificada influência da imagem guiada na qualidade de vida relacionada à saúde neste estudo, as alterações nos dados vitais demonstraram eficácia para a indução de estado de relaxamento. Assim, o relaxamento com imagem guiada por realidade virtual pode ser utilizado com segurança promovendo efeitos benéficos em pacientes submetidos ao transplante de células-tronco hematopoéticas. Os resultados encontrados apontam para a necessidade de ampliação da oferta de práticas integrativas para esses pacientes em face do comprometimento observado na qualidade de vida relacionada à saúde.


The use of guided imagery relaxation can bring benefits to patients undergoing hematopoietic stem cell transplantation by providing relief from physical and emotional symptoms, influencing health-related quality of life. The aim of this study was to analyze changes in the domains of health-related quality of life, and physiological variables, of hospitalized patients who underwent hematopoietic stem cell transplantation and received the guided imagery relaxation by virtual reality technique. This is a quasi-experimental, longitudinal, study carried out in a Bone Marrow Transplantation Service at a public hospital in southern Brazil. From October 2019 to October 2020, 42 adult participants who underwent hematopoietic stem cell transplantation were included, allocated 35 in the intervention group and 7 in the control group, in a 5:1 ratio. For the former, guided imagery relaxation by virtual reality was used as intervention. Blood pressure, heart and respiratory rates, oxygen saturation, temperature and pain were measured immediately before and after the intervention. Data collection took place in four moments : hospitalization (T1), day zero (T2), neutropenia phase (T3) and pre-hospital discharge (T4). Sociodemographic and clinical questionnaires and Functional Assessment of Cancer Therapy-Bone Marrow Transplantation, Functional Assessment of Chronic Illness Therapy-Fatigue and Functional Assessment of Cancer Therapy-Neutropenia were applied to both groups to assess health-related quality of life, and hemogram and leukogram values were evaluated. The results show a general mean age of 37.8 years and an income range of 1 to 3 minimum wages, 21 (70%) participants in the intervention group and five (71.43%) in the control group. Allogeneic transplantation was predominant, 28 (80%) in the intervention group and five (71.43%) in the control group. Leukemias were the most frequent diagnosis in both groups, 13 (34.14%) in the intervention group and three (42.86%) in the control. There were no differences between groups in healthrelated quality of life assessments, however a significant difference was found between the stages and a significant positive correlation between the variables general quality of life, additional concerns, fatigue and neutropenia at all stages for the intervention group. Significant differences were found between the averages of the measurements before and after in heart and respiratory rate, temperature, oxygen saturation and blood pressure in the intervention group. There was a similarity in the behavior of the hemogram and leukogram values and time of engraftment in both groups. The intervention is, in general, well accepted and no evidence of adverse events related to its application has been found. Although there was no influence of the guided imagery on health-related quality of life in this study, changes in vital signs demonstrate efficacy for inducing a state of relaxation. Thus, guided imagery relaxation by virtual reality can be used safely promoting beneficial effects in patients undergoing hematopoietic stem cell transplantation. The results found point to the need to expand the offer of integrative practices for these patients in the face of the impairment observed in healthrelated quality of life.

ABSTRACT

OBJECTIVES@#To establish mouse bone marrow transplantation by pretreatment with chemotherapy, and to explore the dynamic changes of immune cells in the early stage of allogeneic transplantation in the spleen of mice.@*METHODS@#Mice were divided into 4 groups (80 mg/kg group, 100 mg/kg group, 120 mg/kg group, and 150 mg/kg group) according to the difference in dose of busulfan. The mice were treated with busulfan and cyclophosphamide combined chemotherapy, and the appropriate dosage was determined by evaluating the myeloablative effect and drug toxicity. According to the type of the genetic transplantation, the mice were also divided into 4 groups: An allogeneic transplantation group, a homogenic transplantation group, a chemotherapy alone group, and a normal control group. The mice were pretreated with busulfan and cyclophosphamide before bone marrow transplantation. In the allogeneic transplantation group, the suspension of splenocytes was prepared at the first day, the 3rd day, the 5th day, and the 8th day after transplantation for flow cytometry detection, and the dynamic changes of splenic immune cells were analyzed. The homogeneic transplantation group served as the concurrent control, the normal control group served as the control of basic value of spleen immune cells, and the chemotherapy alone group was used to evaluate the myeloablative effect.@*RESULTS@#1) The optimal dose of busulfan was 100 mg/kg. The combination of busulfan and cyclophosphamide can restore the hematopoiesis of transplanted mice, and the toxicity associated with pretreatment is small. 2) In the allogeneic transplantation group: The hematopoietic reconstitution and high donor chimerism rate were achieved after transplantation. In the early phase of bone marrow transplantation, the T lymphocytes were the main cell group, while the recovery of B lymphocytes was relatively delayed. The dendritic cells and natural killer cells from donors were the earliest cells to recover and achieve high chimerism rate compared with T cells and B cells. Most T cells were in the initial T cell state within 5 days after allogeneic transplantation. However, in the 5th day after transplantation, these cells were mainly in the effective memory phenotype. The reconstruction of donor-derived naive T cells was slow, but the reconstruction of donor-derived effective memory T cells and regulatory T cells was relatively fast. 3) In the homogeneic transplantation group: The mice could recover hematopoiesis and the recovery of B lymphocytes was delayed. 4) In the chemotherapy alone group: All mice died in 12-15 days after chemotherapy, and the peripheral blood routine showed pancytopenia before death.@*CONCLUSIONS@#Pretreatment with chemotherapy can successfully establish the mouse model of bone marrow transplantation. There are difference in the proportion of T cells, B cells, natural killer cells, dendritic cells, effector memory T cells, initial T cells, and regulatory T cells after transplantation, and the relationship between donor and recipient is also changed.

ABSTRACT

OBJECTIVE@#To establish the aGVHD mouse model,and investigate the regulatory effect and its mechanism of low-dose GSI combined with BMSC on aGVHD mice.@*METHODS@#C57BL/6 (H-2b) and BALB/c (H-2d) were selected as donor and recipient of allogeneic transplantation to establish the aGVHD mouse model. BALB/c mice were randomly divided into 6 groups, which were the bone marrow cell infusion after irradiation (BM) group; the bone marrow cells + spleen cells after irradiation (BM+SC) group; the bone marrow cells + spleen cells + DMSO (BM+SC+DMSO) (transplant control) group; bone marrow cells + splenocytes +GSI after irradiation (BM+SC+GSI) group; bone marrow cells + spleen cells + bone marrow mesenchymal stromal infusion after irradiation cell (BM+SC+BMSC) group; bone marrow cells + spleen cells + bone marrow mesenchymal stromal cells +GSI infused after irradiation (BM+SC+BMSC+GSI) group. The mice in the two groups containing GSI were intraperitoneally injected with GSI at 5 μmol/kg on day 1, 2, and 3 after transplantation with DMSO as a control. The general conditions, survival time and hematopoietic recovery of mice were observed, cytokines were detected by ELISA, and histopathological changes were detected by immunohistochemistry. The effects of low-dose GSI combined with BMSC on hematopoietic reconstruction and aGVHD development after allo-BMT were investigated.@*RESULTS@#The survival rate of the mice in BM+SC+BMSC+GSI combination group was 80% during the observation period, which was significantly higher than that in the other groups; the incidence of aGVHD was reduced in the BMSC GSI or their combination groups after 21 days of transplantation. GSI could partly promote the recovery of leukocytes, and show no significant delayed effect on the recovery platelets. Moreover, the level of Th1 cytokines (IFN-γ) in BM+SC+BMSC+GSI combined group was lower than that in BM+SC+GSI group (P<0.01), the level of Th2 cytokines (IL-4) in the combination group was higher than that in BM+SC+GSI group (P<0.01), also the level of IL-17 was significantly lower than that in the corresponding control group (P<0.001).@*CONCLUSION@#Low dose GSI combined with BMSC can promote hematopoietic reconstruction and regulate cytokines secretion including IFN-γ, IL-4 and IL-17. GSI combined with BMSC achieve the goal of synergistically inhibiting the occurrence and progression of aGVHD.

ABSTRACT

OBJECTIVE@#To establish a mouse mixed chimerism (MC) model of nonmyeloablative allogeneic bone marrow transplantation(allo-BMT) and explore its affecting factors.@*METHODS@#The MC model was established by nonmyeloablative allo-BMT followed by high-dose post-transplant cyclophosphamide (PTCY). 123 mice in the experiments was retrospectively analyzed, and the factors related with the chimerism were explored with the univariate and multivariate logistic regression analysis. A multivariate linear regression was performed by R project to obtain a mathematical model for predicting the chimeric level with relevant affecting factors.@*RESULTS@#The model presented mixed chimerism on day 14 after transplantation, and was characterized by a donor lymphocyte infusion (DLI) which significantly promoted donor engraftment on day 15, but transfplantation of PBS in control group was failed. Among 123 mice, 47 (38.21%) mice were MC, while 76 (61.79%) mice were non-MC in 123 mice, respectively; univariate analysis showed that the baseline body weight of mice (P=0.001, 17.84±1.19 g vs 18.50±0.94 g), total body irradiation(TBI,P=0.048) and the using of cyclophosphamide (P=0.16) were affected the chimeric state of mice, while the number of infusing cells and the time of detection showed no significant effects. Multivariate regression analysis showed that under certain conditions, the body weight of mice on day 0 was an independent factor affecting chimeric levels (OR=0.493, 95% CI 0.307-0.791, P=0.003). Through R project multiple linear regression, the math model was achieved, which was chimerism=6.09-12×weight(g)+80.03×TBI(Gy)-4.4×cell-counts (× 10@*CONCLUSION@#The experiment presents a method for establishing a mixed chimeric mice model after non-myeloablative bone marrow transplantation and constructs a mathematical model with relevant factors affected chimerism status.

ABSTRACT

ABSTRACT Objective: to analyze adherence to the nursing guidelines for home care of bone marrow transplant recipients from an ecosystem perspective. Method: descriptive, exploratory study with a qualitative approach, using Content Analysis for data analysis, with theoretical and philosophical ecosystem support. The interviews, carried out in bone marrow transplant services, in Brazil and Spain, were guided by an instrument developed by the researchers which contained 25 closed and ten open questions. 40 users participated who met the inclusion criteria. Data collection was carried out from July 2016 to October 2017. Results: the Orientations category emerged from the data which then gave rise to the subcategories: Interactive relational actions; and, actions and behaviors that interfered in the success of the transplant. Some users, due to excessive information at the time of discharge, were unable to assimilate or carry out the guidelines received; others, during the hospitalization phase, apprehended them and absorbed them in order to use them in the home ecosystem space after transplantation. Conclusion: part of the users followed only the guidelines that best adapted to their daily lives and, for others, after hospital discharge, they caused doubts and insecurities regarding the care to be performed at home. It is necessary for the user to identify the constituent elements of their home ecosystem and learn, through communication and information, how they interfere in post-hospital discharge care. Therefore, it is necessary to create communication and information mechanisms that enable the dynamic process between the constituent elements of the ecosystem, biotic and abiotic, so that they have interaction and sustainability and can be practiced by the user.


RESUMEN Objetivo: analizar el cumplimiento de las directrices de la enfermera para el cuidado domiciliario de los receptores de trasplante de médula ósea en una perspectiva ecosistémica. Método: descriptivo, exploratorio, con un enfoque cualitativo, utilizando el análisis de contenido para el análisis de datos, con soporte teórico y filosófico del ecosistema. Las entrevistas, realizadas en los servicios de trasplante de médula ósea, en Brasil y España, fueron guiadas por un instrumento desarrollado por los investigadores, que contenía 25 preguntas cerradas y diez abiertas. Participaron 40 usuarios que cumplieron con los criterios de inclusión. La recolección de datos se realizó entre julio de 2016 y octubre de 2017. Resultados: la categoría Orientaciones surgió de los datos y originó las subcategorías: acciones relacionales interactivas, acciones y comportamientos que interfirieron en el éxito del trasplante. Algunos usuarios, debido a la información excesiva al momento del alta, no pudieron asimilar y llevar a cabo las pautas recibidas, otros, en el curso de la fase de hospitalización, los detuvieron para absorberlos para su atención en el espacio del ecosistema del hogar en el pos trasplante. Conclusión: parte de lós usuários siguió solo las pautas que mejor se adaptaron a su vida diaria y para otros, después del alta hospitalaria, causaron dudas e inseguridades com respecto a La atención que se practica em elhogar. Es necesario que el usuario identifique los elementos constitutivos del ecosistema de su hogar y aprenda, a través de la comunicación y la información, cómo interfieren en la atención hospitalaria posterior al alta. Por lo tanto, es necesario crear mecanismos de comunicación e información que permitan el proceso dinámico entre los elementos constitutivos del ecosistema, bióticos y abióticos, para que tengan interacción y sostenibilidad y puedan ser practicados por el usuario.


RESUMO Objetivo: analisar a adesão às orientações do enfermeiro para o cuidado domiciliar do transplantado de medula óssea na perspectiva ecossistêmica. Método: descritivo, exploratório, com abordagem qualitativa, utilizando-se para a análise dos dados a Análise de Conteúdo, com apoio teórico-filosófico ecossistêmico. As entrevistas, realizadas em serviços de transplante de medula óssea, no Brasil e Espanha, foram norteadas por um instrumento elaborado pelas pesquisadoras, contendo 25 questões fechadas e dez abertas. Participaram 40 usuários que cumpriram os critérios de inclusão. A coleta de dados foi realizada de julho de 2016 a outubro de 2017. Resultados: a categoria Orientações emergiu dos dados e originou as subcategorias: Ações relacionais interativas; e, ações e comportamentos que interferiram no sucesso do transplante. Alguns usuários, por excesso de informações no momento da alta, não conseguiram assimilar e desempenhar as orientações recebidas; outros, no transcorrer da fase de internação, as apreenderam absorvê-las para o cuidado no espaço ecossistêmico domiciliar no pós-transplante. Conclusão: parte dos usuários seguiu somente as orientações que melhor se adaptaram ao seu cotidiano e, para outros, no pós-alta hospitalar, ocasionaram dúvidas e inseguranças em relação ao cuidado a ser praticado no domicílio. Faz-se necessário que o usuário identifique os elementos constituintes do seu ecossistema domiciliar e conheça, por meio da comunicação e informação, como interferem no cuidado pós alta hospitalar. Portanto, é preciso criar mecanismos de comunicação e informação que possibilitem o processo dinâmico entre os elementos constituintes do ecossistema, bióticos e abióticos, para que tenham interação e sustentabilidade e possam ser praticados pelo usuário.

ABSTRACT

Abstract We retrospectively analyzed 570 adult patients who received allogeneic stem cell transplantation for malignant diseases. The outcomes were compared according to donor type. Most of the patients (60%) were transplanted for acute leukemia. Median follow-up was 1.6 years. Haploidentical allogeneic stem cell transplantation was more frequently performed for acute myeloid leukemia and in late stages than any other donor type. Non-relapse mortality at 100 days and one year for unrelated and haploidentical donors were similar, 19%-29% vs. 17%-28%, respectively. A significant better non-relapse mortality was observed for matched sibling donors (7%-15%; p < 0.001). Relapse rate was higher in haploidentical donors compared to matched sibling and unrelated donors (three year relapse rate 46%, 39%, 28%; respectively p < 0.001). Haploidentical donors resulted in lower three year progression-free survival and worse 3 year overall survival (32%; p < 0.001 and 42%; p < 0.001) compared with other donors (44% and 55% MSD, 40% and 42% UD, respectively). The incidence of grade II-IV acute graft-versus-host disease was higher in unrelated donors (51% unrelated, 35% haploidentical, 36% matched sibling; respectively; p = 0.001), with no difference in grades III-IV (p = 0.73) or in chronic graft-versus-host disease (p = 0.2) between groups. After multivariate analysis, haploidentical and unrelated donors remained negatively associated with non-relapse mortality (HR 1.95; 95% CI 1.10-3.20 and HR 2.70; 95% CI 1.63-4.46, respectively). Haploidentical donors were associated with a higher risk of relapse and worse overall survival. This analysis shows that haploidentical donors were associated with similar non-relpase mortality and higher relapse rates than unrelated donors. Better results in non-relapse mortality were observed for matched sibling donors.


Resumen Se efectuó un análisis retrospectivo de 570 pacientes adultos que recibieron un trasplante alogénico de precursores hematopoyéticos, comparando los resultados según el tipo de donante. La mediana de seguimiento fue de 1.6 años. El 60% de la población se trasplantó por leucemias agudas. Los trasplantes haploidénticos se hicieron en su mayoría en leucemia mieloide aguda y en estadios tardíos en comparación a otros donantes. La mortalidad libre de enfermedad al día +100 y a 1 año fue similar para los donantes no emparentados y haploidénticos (19% y 29% vs. 17% y 28%, respectivamente). Se obtuvieron mejores resultados con donantes relacionados idénticos (7% y 15%; p < 0.001). La recaída fue mayor en los donantes haploidénticos (tres años 46% haploidénticos, 39% relacionados idénticos, 28% no emparentados; p < 0.003). El trasplante con donante haploidéntico presentó una menor supervivencia libre de progresión y menor supervivencia global a tres años (32%; p < 0.001 y 42%; p < 0.001). La incidencia de enfermedad injerto contra huésped aguda fue mayor en no emparentados (51%, 35% haploidénticos, 36% relacionados idénticos; p = 0.001), sin diferencias en grados III-IV (p = 0.73) o en EICH crónica (p = 0.2). Los trasplantes con donante haploidéntico y no emparentado mantuvieron su asociación negativa con mortalidad libre de enfermedad (HR 1.95; 95%IC 1.10-3.20 y HR 2.70; 95%IC 1.63-4.46), en análisis multivariado. El trasplante haploidéntico se asoció a mayor recaída y a menor supervivencia global. Esta experiencia mostró similar mortalidad libre de enfermedad entre trasplantes con donantes haploidénticos y no emparentados. Los trasplantes relacionados idénticos mostraron menores tasas de mortalidad libre de enfermedad.

ABSTRACT

El trasplante de médula ósea es una terapia potencialmente curativa para múltiples enfermedades; el alogénico es el más indicado en leucemias. La enfermedad injerto versus huésped (EIVH) constituye la principal complicación del trasplante de médula ósea alogénico. Tanto en la EIVH aguda como crónica, la piel es el órgano más frecuentemente comprometido. El objetivo fue analizar las manifestaciones cutáneas de esta entidad. Trabajo retrospectivo y descriptivo, que incluyó a 59 pacientes trasplantados de edades entre 0 y 20 años. En 50 casos, se realizó trasplante de médula ósea alogénico. Veinticinco pacientes desarrollaron EIVH (17, la forma aguda, y 8, la forma crónica), y 24 tuvieron compromiso cutáneo. En concordancia con lo comunicado se encontró que las manifestaciones cutáneas fueron la manifestación clínica más común de EIVH. El hallazgo principal en EIVH aguda en nuestra serie fue el rash eritematoso maculopapular y, en EIVH crónica, las lesiones escleróticas símil morf


Bone marrow transplant is a potentially curative therapy for several diseases, and allogeneic bone marrow transplant is the most commonly indicated type for leukemias. Graft versus host disease (GVHD) is the main complication of allogeneic bone marrow transplant. In both acute and chronic GVHD, the skin is the most frequently involved organ. The objective of this study was to analyze cutaneous manifestations of this disease. Retrospective and descriptive study that included 59 transplanted patients aged 0 to 20 years. In 50 cases allogeneic bone marrow transplant was performed. Twenty-five patients developed GVHD (17 acute disease and 8 chronic disease) and 24 of them had cutaneous involvement. According to the literature, skin compromise was the commonest clinical manifestation of GVHD. Main finding in acute GVHD in our series was the erythematous maculopapular rash, while in chronic GVHD they were sclerotic lesions resembling morphe

ABSTRACT

No Transplante de Medula Óssea (TMO) de crianças e adolescentes, a mãe geralmente é a acompanhante no período de hospitalização. Ao assumir esse papel, ela é exposta a uma série de eventos estressores, além de lidar com o risco de perda do filho. Este estudo teve por objetivo compreender como mães vivenciam o cuidado de crianças e adolescentes submetidos ao TMO. Trata-se de uma pesquisa descritiva e exploratória, de abordagem clínico-qualitativa, com recorte transversal. Participaram seis mães, com idades entre 39 a 49 anos. Para a coleta de dados utilizou-se um roteiro de entrevista semiestruturada. As entrevistas individuais foram audiogravadas e transcritas na íntegra, e os conteúdos foram submetido à análise temática. Os resultados indicam que as mães vivenciam, de um lado, as angústias relacionadas às incertezas que o TMO implica e, por outro, a perspectiva da cura, que alimenta a esperança de salvar a vida do filho, mesmo com o longo caminho a ser percorrido. As mães buscam restaurar suas forças e preservar seu equilíbrio psíquico por meio da rede de apoio social e do apego à fé, que caracterizam os recursos de enfrentamento mais utilizados. Investigar o cuidado na perspectiva das mães permite conhecer como elas compreendem e lidam com o tratamento do filho submetido ao TMO, o que pode favorecer a elaboração de estratégias de intervenção a serem oferecidas pela equipe multiprofissional.


In Bone Marrow Transplantation (BMT) of children and adolescents, the mother is usually the companion during the hospitalization period. In assuming this role, she is exposed to a series of stressful events, in addition to dealing with the risk of losing her child. This study aimed to understand how mothers experience the care of children and adolescents submitted to BMT. This is a descriptive and exploratory research, with a clinical-qualitative approach, with a transversal cut. Six mothers participated, aged 39 to 49 years. For data collection, a semi-structured interview script was used. The individual interviews were audio recorded and transcribed in full, and the contents were subjected to thematic analysis. The results indicate that mothers experience, on the one hand, the anxieties related to the uncertainties that BMT implies and, on the other, the perspective of healing, which feeds the hope of saving the child's life, even with the long way to go. Mothers seek to restore their strength and preserve their psychic balance through the social support network and the attachment to faith, which characterize the most used coping resources. Investigating care from the mothers' perspective allows to know how they understand and deal with the treatment of the child submitted to BMT, which can favor the development of intervention strategies to be offered by the multiprofessional team.

ABSTRACT

Los trastornos heredados del metabolismo son enfermedades graves de la infancia que cursan con un gran deterioro cognitivo y del desarrollo psicomotor. La fisiopatología del progresivo deterioro del sistema nervioso suele estar asociada a una severa neuroinflamación y desmielinización, y como consecuencia, neurodegeneración. Por el momento no tienen cura y precisan de actitudes terapéuticas precoces y agresivas, que conllevan altas tasas de mortalidad y, muy frecuentemente, escasos grados de mejoría funcional y supervivencia. El trasplante de médula ósea y de células mesenquimales de médula ósea son terapias de elección y experimentales que consiguen mejorar el curso de estas enfermedades mediante diferentes mecanismos de acción: remplazo de enzima deficiente, intercambio de membranas y regulación del proceso inflamatorio.


Inherited metabolism disorders are serious childhood diseases that lead to significant cognitive impairment and regression of psychomotor development. The pathophysiology of the neural progressive deterioration is usually associated with severe neuroinflammation and demyelination, and as a consequence, neurodegeneration. At the moment they have no adequate treatment and require early and aggressive therapeutic approaches, which entail high mortality rates and, very frequently, low degrees of functional improvement and survival. Bone marrow transplantation and bone marrow mesenchymal cells grafts are therapeutic and experimental therapies that improve the course of these diseases through different mechanisms of action: enzyme replacement, membrane exchange and regulation of the inflammatory process.

ABSTRACT

The Hematopoietic stem cell transplantation (HSCT) is used in children as a definitive treatment for various oncological, immune deficiencies, hemoglobinopathy, and malignancies diseases that involve the hematological system, congenital metabolism disorders, among others. To characterize the clinical and epidemiological profile of children and adolescents submitted to HSCT at a referral service in the state of Rio Grande do Norte. This is a quantitative, retrospective, observational, descriptive and analytical quantitative approach approaching the medical records of children and adolescents submitted to HSCT in a referral hospital service for this type of transplantation in the state of Rio Grande do Sul North (RN). The final sample consisted of 35 records patients aged between 2 and 18 years old who underwent HSCT from February 2008 to December 2015 and who presented the data necessary for the study. The records analyzed showed a littlemajority of male patients (51.42%) and 60.00% of these men were students and 71.42% lived in the state of the Rio Grande do Norte. According to the clinical characteristics, 34.3% of the patients had Acute Lymphoblastic Leukemia and 25.71% had Acute Myeloid Leukemia as the main diagnosis. Gastrointestinal toxicities were the most frequent (97.1%) and all patients received antineoplastic/chemotherapeutic and antiemetic treatment. The allogeneic HSCT was the most frequently performed (57.14%) and the most used source of Hematopoietic progenitor cells (HPC) was the peripheral blood (54.29%) and 5.71% of these patients developed the Graft versus Host Disease (GVHD), of which one was affected by acute GVHD and another by chronic GVHD. Septsis was the most frequent cause of death (60%). The profile of the clinical variables presented by the children and adolescents of this study shows that the most prevalent diagnosis was ALL, the most frequent toxicities were gastrointestinal, cardiac, respiratory and hematological, the most common HSCT was allogeneic peripheral blood and the greatest cause of mortality was sepsis. These data are similar to studies conducted in North America, Europe and Asia.


O Transplante de Células-Tronco Hematopoéticas (TCTH) é utilizado em crianças como um tratamento definitivo para várias doenças oncológicas, imunodeficiências, hemoglobinopatias, malignidades que envolvem o sistema hematológico, distúrbios de metabolismo congênito, entre outros. Caracterizar o perfil clínico e epidemiológico de crianças e adolescentes submetidos ao TCTH em um serviço de referência do estado do Rio Grande do Norte. Trata de um estudo epidemiológico de abordagem quantitativa, do tipo coorte retrospectiva, observacional, descritivo e analítico onde foram abordados os prontuários de crianças eadolescentes submetidos ao TCTH em um serviço hospitalar de referência para esse tipo de transplante no estado do Rio Grande do Norte (RN). A amostra final foi composta por 35 prontuários de pacientes com idade entre dois e 18 anos que realizaram o TCTH no período de fevereiro de 2008 a dezembro de 2015 e que apresentavam os dados necessários ao estudo. Do total de prontuários analisados houve discreta maioria de pacientes do sexo masculino (51,42%). Destes, 60,00% eram estudantes e 71,42% residiam no estado do RN. De acordo com as características clínicas, 34,3% apresentaram como diagnóstico principal a Leucemia Linfoblástica Aguda e 25,71% a Leucemia Mieloide Aguda. As toxicidades gastrointestinais foram as que mais ocorreram (97,1%) e todos receberam tratamento com antineoplásicos/quimioterápicos e antieméticos. O TCTH alogênico foi o mais frequentemente realizado (57,14%) e a fonte de CPH mais utilizada foi o sangue periférico (54,29%) e 5,71% desenvolveram a Doença do Enxerto Contra Hospedeiro (DECH), dos quais um foi acometido por DECH aguda e outro pela forma crônica. A causa de morte com maior frequência foi a sepse (60%). O perfil das variáveis clínicas apresentadas pelas crianças e adolescents desta pesquisa mostram que o diagnóstico mais prevalente foi o de LLA, as toxicidades que mais ocorreram foram as gastrointestinais, cardíacas, respiratórias e hematológicas, o TCTH mais realizado foi o alogênico de sangue periférico e a maior causa de mortalidade foi a sepse. Tais dados se assemelham aos estudos realizados na América do Norte,Europa e Ásia.

ABSTRACT

OBJECTIVE@#To observe the dynamic changes of hematopoietic reconstitution and multiple lineages differentiation at early phase after transplantation.@*METHODS@#Whole bone marrow mononuclear cells (wBMMNC, 5×10) and enriched c-Kit hematopoietic stem/progenitor cells (HSPC, 3×10) from the BM of B6-Ly5.1 mice were transplanted into lethally irradiated B6-Ly5.2 mice, the frequencies and absolute numbers of donor-derived cells (including LKS and LKS) were detected by flow cytometry. The multiple lineages differentiation of donor-derived cells was also monitored by flow cytometry. The homing and early phase proliferations of donor-derived cells were observed by two-photon microscope.@*RESULTS@#The donor-derived cells started to proliferation from 5-7 days after transplantation and reached the peak value at 2-3 weeks after wBMMNC transplantation. The donor-derived cells proliferated from 1-2 weeks and maintained until 4 weeks after c-kitHSPC transplantation. At 1 week after transplantation, the donor-derived cells mainly differentiated into myeloid cells with a few lymphoid cells production (B cells) but the production of T cells was not observed at most in wBMMNC transplanted group, while myeloid cells occupied the majority of donor-derived cells at 2-4 weeks; donor-derived cells almost totally differentiated into myeloid cells at 1-3 weeks after transplantation in c-Kit transplanted group and donor-derived B cells appeared at 4 weeks. The absolute number of donor-derived LKS and LKS cells in the BM of c-Kit transplanted group were much higher than that of wBMMNC group (P<0.001) at 2 weeks respectively. The clustering proliferation of cKit cells at 4-5 days after transplantation was observed by two photon microscope.@*CONCLUSION@#The dynamical rate of proliferation and reconstitution of donor-derived cells are much earlier and quicker in c-Kit group than those of wBMMNC group. c-Kit cells mainly differentiate into myeloid cells within 1-3 weeks and the lymphoid cell differentiation starts at 4 weeks after transplantation. The immediate proliferation and differentiation of c-Kit cells within 1 week maybe due to the urgent needs of hematopoietic regeneration under the myeloablated hosts.
