ABSTRACT

Introducción: El trasplante de células progenitoras hematopoyéticas (TPH) en niños es un procedimiento no exento de complicaciones graves. El ingreso de esta población a unidades de cuidados intensivos pediátricos (UCIP) se asocia con elevada mortalidad. Objetivos: Analizar la sobrevida y los factores predictivos de la mortalidad en niños que recibieron TPH e ingresaron a la UCIP y elaborar un modelo predictivo de mortalidad en esta población. Materiales y métodos: Revisión retrospectiva de niños y adolescentes que recibieron un TPH entre el 01/01/2005 y el 31/12/2019 e ingresaron a la UCIP de un hospital universitario de alta complejidad. Resultados: De un total de 264 niños que recibieron el trasplante, 114 ingresaron a la UCIP. La mortalidad general fue del 29 % (n = 34). El tipo de trasplante, enfermedad basal, evento de neutropenia febril, infección por citomegalovirus, insuficiencia respiratoria, enfermedad de injerto contra huésped (EICH), quimioterapia mieloablativa y desnutrición previa se asociaron con tasas de mortalidad más elevadas. En el análisis multivariado, la EICH (razón de posibilidades [OR, por su sigla en inglés]: 2,23; intervalo de confianza del 95 % [IC 95 %]: 1,92-2,98), la necesidad de ventilación mecánica invasiva (OR: 2,47; IC95 %: 1,39-5,73), el trasplante de donante alternativo (OR: 1,58; IC 95 %: 1,14-2,17) y la desnutrición previa (OR: 1,78; IC 95 %: 1,223-3,89) se asociaron con mayor mortalidad. Conclusión: En la población estudiada, dos de cada tres niños que recibieron TPH e ingresaron a la UCIP sobrevivieron. La EICH, ventilación mecánica, trasplante de donante alternativo y desnutrición previa fueron factores predictivos de mortalidad


Introduction: Hematopoietic stem cell transplantation (HSCT) in children is a procedure that is not exempt of severe complications. Admission to the pediatric intensive care unit (PICU) is associated with a high mortality rate. Objectives: To analyze survival and predictors of mortality among children who received a HSCT and were admitted to the PICU, and to develop a mortality prediction model in this population. Materials and methods: Retrospective review of children and adolescents who received a HSCT between January 1st, 2005 and December 31st, 2019 and were admitted to the PICU of a tertiary care teaching hospital. Results: Out of 264 children receiving the transplant 114 were admitted to the PICU. The overall mortality rate was 29 % (n = 34). The type of transplant, underlying disease, febrile neutropenia event, cytomegalovirus infection, respiratory failure, graft versus host disease (GVHD), myeloablative chemotherapy, and previous malnutrition were associated with higher mortality rates. In the multivariate analysis, GVHD (odds ratio [OR]: 2.23; 95 % confidence interval [CI]: 1.92-2.98), need for mechanical ventilation (OR: 2.47; 95 % CI: 1.39-5.73), alternative donor transplant (OR: 1.58; 95 % CI: 1.14-2.17), and previous malnutrition (OR: 1.78; 95 % CI: 1.22-3.89) were associated with a higher mortality rate. Conclusion: In the studied population, 2 out of 3 children who received a HSCT and were admitted to the PICU survived. GVHD, mechanical ventilation, alternative donor transplant, and previous malnutrition were predictors of mortality

ABSTRACT

Resumen Las infecciones fúngicas invasoras (IFI) constituyen una de las principales complicaciones infecciosas en pacientes oncohematológicos y con trasplante de células progenitoras hematopoyéticas (TCPH), ocasionando alta morbimortalidad e incrementando significativamente los costos de atención y la estadía hos pitalaria. La epidemiología de las IFI ha cambiado en las últimas décadas, siendo los hongos filamentosos, particularmente Aspergillus spp., los principales agentes etiológicos. Existen múltiples factores de riesgo para una IFI; pero la neutropenia profunda y prolongada, y la inmunodeficiencia celular severa siguen siendo los más importantes. Por este motivo, la población de mayor riesgo la constituyen los pacientes con leucemias agudas, mielodisplasias y TCPH alogénicos con enfermedad injerto contra huésped (EICH), en tratamiento con corticoides. Numerosos ensayos clínicos aleatorizados y metaanálisis han demostrado que la profilaxis antifúngica primaria (PAF) reduce significativamente la incidencia de IFI, tanto de aquellas causadas por Candida spp. como por Aspergillus spp., la mortalidad relacionada a IFI y la mortalidad global en algunos grupos de pacientes. Asimismo, en enfermos de alto riesgo, en donde se espera una incidencia de IFI elevada, es una estrategia costo-efectiva. Varios antifúngicos han demostrado beneficio clínico y pueden utilizarse como estrategia de PAF en diferentes escenarios, presentando ventajas y desventajas que deben ser tenidas en cuenta al momento de indicar una PAF. Para esto, sociedades científicas nacionales e internacionales, han emitido recomendaciones de indicación de PAF. Se analizan los aspectos relacionados con la eficacia clínica de los diferentes antifúngicos según la población de riesgo, las potenciales desventajas, momento y forma de administración.


Abstract Invasive fungal infections (IFI) are among the main infectious complications in patients with hema tological malignancies and with hematopoietic stem cell transplant (HSCT), causing high morbidity and mortality and significantly increasing the healthcare cost and hospital stay. The epidemiology of IFIs has changed in recent decades, with filamentous fungi, particularly Aspergillus spp., being the main etiological agents. There are multiple risk factors for having an IFI; however, the most important are profound and prolonged neutropenia and severe cellular immunodeficiency. For this reason, the population at greatest risk is made up of patients with acute leukemias, myelodysplasias and allogeneic HSCT with graft-versus-host disease (GVHD) treated with cortico steroids. Numerous randomized clinical trials and meta-analyses have shown that primary antifungal prophylaxis (AFP) significantly reduces the incidence of IFI, particularly those caused by Candida spp. and Aspergillus spp., IFI-related mortality, and overall mortality in some group of patients. Likewise, in high-risk patients, where a high incidence of IFI is expected, it is a cost-effective strategy. Several antifungals have demonstrated clinical benefit. They can be used as a AFP strategy in different settings, presenting advantages and disadvantages that must be taken into account in each case. For this, national and international scientific societies have issued recom mendations for the indication of AFP. Aspects related to the different antifungals' clinical efficacy are analyzed considering the population at risk, the potential disadvantages, timing, and form of administration.

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

Introducción: La infección por citomegalovirus es muy frecuente en pacientes sometidos a trasplante de progenitores hematopoyéticos, debido a tratamientos mieloablativos de acondicionamiento, disparidad genética y al tratamiento inmunosupresor, y ocurre fundamentalmente después de la toma del implante. Objetivos: Actualizar el diagnóstico, manejo y seguimiento de la infección por citomegalovirus en pacientes trasplantados. Métodos: Se realizó revisión bibliográfica en los idiomas español e inglés, utilizando los motores de búsqueda de Pubmed, Google Académico y Scielo sobre el diagnóstico y manejo del citomegalovirus en pacientes receptores de trasplante hematopoyético. Análisis y síntesis de la información: Se recolectó y organizó la información obtenida siguiendo cronológicamente el surgimiento de técnicas para diagnóstico y la aparición de nuevos medicamentos en los últimos años. Se seleccionaron artículos recientes de expertos en el tema en revistas prestigiosas, donde se evidencia la importancia del diagnóstico adelantado y el inicio del tratamiento. Conclusiones: En la actualidad se cuenta con nuevas formas de diagnóstico y medicamentos novedosos para el citomegalovirus, pero la mortalidad puede llegar a ser alta, si el paciente no es tratado antes de que aparezcan los síntomas de la enfermedad e incluso a pesar del tratamiento. En ocasiones, no es posible erradicar el virus, lo que lleva a complicaciones importantes y a la muerte. La enfermedad citomegálica continúa siendo una complicación frecuente en estos pacientes a pesar de las medidas para evitar su reactivación(AU)


Introduction: Cytomegalovirus infection is very common in patients undergoing hematopoietic progenitor transplantation, due to myeloablative conditioning treatments, genetic disparity, and immunosuppressive treatment, and occurs mainly after the engrafment. Objective: A review and update of the diagnosis and management of cytomegalovirus is made in hematopoietic transplant recipients. Method: A bibliographic review was carried out in Spanish and English, using the search engines of Pubmed, Scholar Google and Scielo about the diagnosis and management of cytomegalovirus in hematopoietic transplant recipients. Development: The information obtained was collected and organized chronologically about the emergence of techniques for diagnosis and the appearance of new drugs in recent years. Recent articles by experts in prestigious journals were reviewed and the importance of early diagnosis and initiation of treatment is evidenced. Conclusions: There are currently new forms of diagnosis and novel medications, but mortality can be high, if the patient is not treated before the symptoms of the disease appear and even despite treatment, sometimes it is not possible to eradicate the virus, leading to major complications and death. Cytomegalic disease continues to be a frequent complication in these patients despite measures to prevent virus reactivation(AU)

ABSTRACT

Abstract Chagas disease (CD) is a protozoan zoonosis caused by Trypanosoma cruzi. Reactivation of CD occurs via drug-induced immunosuppression before and during transplantation. Here, we report the case of a 62-year-old man diagnosed with classic Hodgkin lymphoma who received highly aggressive conditioning chemotherapy before undergoing stem cell transplantation (SCT). The patient tested positive for CD in pre-transplantation evaluation. The patient exhibited persistent fever and elevated C-reactive protein levels before and after SCT, and was treated with antibiotics. Micro-Strout test showed evidence of trypomastigotes and he was treated with benznidazole until tested negative. Post-transplantation seropositive patients should be screened for possible reactivation.

ABSTRACT

OBJECTIVE@#To detect fusion gene with pathological significance in a patient with refractory and relapsed acute B cell lymphoblastic leukemia (B-ALL) and to explore its laboratory and clinical characteristics.@*METHODS@#Transcriptome sequencing was used to detect potential fusion transcripts. Other laboratory results and clinical data of the patient were also analyzed.@*RESULTS@#The patient was found to harbor TCF3 exon 17-ZNF384 exon 7 in-frame fusion transcript. The minimal residual disease (MRD) has remained positive after multiple chemotherapy protocols including CD19-, CD22- targeted chimeric antigen receptor T cells immunotherapy. The patient eventually achieved complete remission and sustained MRD negativity after allogeneic hemopoietic stem cell transplantation (allo-HSCT).@*CONCLUSION@#Transcriptome sequencing can effectively detect potential fusion genes with clinical significance in leukemia. TCF3-ZNF384 positive B-ALL has unique laboratory and clinical characteristics, may not well respond to chemotherapy and immunotherapy, and is more likely to relapse. Timely allo-HSCT treatment may help such patients to achieve long-term disease-free survival. TCF3-ZNF384 positive B-ALL is not uncommon in pediatric patients but has not been effectively identified.

ABSTRACT

Introdução: O tratamento da leucemia linfoblástica aguda (LLA) atualmente baseia-se em quimioterapia e/ou transplante de células tronco hematopoiéticas; entretanto, uma nova terapia vem se tornando promissora: a imunoterapia com células T modificadas geneticamente que expressam um receptor de antígeno quimérico (CAR-T) visando antígenos específicos presente em blastos de LLA, gerando resultados promissores em crianças e adultos com doença recidivada e refratária (r/r). Objetivo: Discorrer sobre a LLA e descrever a imunoterapia com CAR-T, como inovação terapêutica no tratamento da LLA de linhagem B. Método: Foi realizada uma revisão bibliográfica por meio de publicações indexadas nas bases de dados Scielo e Pubmed, utilizando os descritores: leucemia linfoblástica aguda de células B; células CAR-T; receptores de antígeno quimérico, recidivados/refratários; imunoterapia. Resultados: As altas taxas de remissão completa (42% até 100%) e parcial (28,5%) da LLA (r/r) tratadas com CAR-T, possibilitam um aumento considerável da sobrevida geral comparado a outros tratamentos convencionais. Efeitos desfavoráveis, tais como síndrome da liberação de citocinas (CRS) (0 até 90%) e neurotoxicidade (NT) (0 até 29%) podem ser vistos, sendo manejáveis, não prejudicando o desfecho do tratamento. Conclusão: A LLA é uma doença grave, de difícil tratamento e prognóstico reservado. A imunoterapia vêm se mostrando promissora à essa enfermidade, principalmente em casos de doença r/r se mostrado uma ferramenta poderosa que permite o foco específico de células malignas por meio de engenharia de células T


Introduction: The treatment of acute lymphoblastic leukemia (ALL) is currently based on chemotherapy and/or hematopoietic stem cell transplantation; however, a new therapy is becoming promising: immunotherapy with genetically modified T cells that express a chimeric antigen receptor (CAR-T) targeting specific antigens present on ALL blasts, reaching promising results in children and adults with relapsed and refractory disease (r/r). Objective: To discuss ALL and describe immunotherapy with CAR-T as a therapeutic innovation in the treatment of B-lineage ALL. Method: A literature review was carried out through publications indexed in the Scielo and Pubmed databases, using the following descriptors: B-cell acute lymphoblastic leukemia; CAR-T cells; chimeric antigen receptors, relapsed/refractory; immunotherapy. Results: The high rates of complete (42% to 100%) and partial remission (28.5%) of ALL (r/r) treated with CAR-T allows a considerable increase in overall survival compared to other conventional treatments. Unfavorable effects such as cytokine release syndrome (CRS) (0 to 90%) and neurotoxicity (NT) (0 to 29%) can be seen, being manageable, not impairing the treatment outcome. Conclusion: ALL is a serious disease, with a difficult treatment and poor prognosis. Immunotherapy has shown benefits for this disease, especially in cases of r/r ALL, showing itself to be a powerful tool that allows the specific focus of malignant cells through T cell engineering.

ABSTRACT

Esse estudo observacional transversal comparativo teve como objetivos avaliar os parâmetros clínicos periodontais, índice gengival modificado (IGM), índice de placa visível (IPV), crescimento gengival induzido por drogas (CGID), mensurar volume e fluxo do fluido crevicular gengival (FCG), perda dentária bem como o impacto da saúde bucal auto-relatada na qualidade de vida, em pacientes pré e pós-transplante de células tronco hematopoiéticas (TCTH), fígado (TX-fígado), rim (Tx-rim), comparados a indivíduos sem doença sistêmica diagnosticada. O estudo foi aprovado pelo Comitê de Ética em Pesquisa da Universidade Federal de Minas Gerais (UFMG) (CAAE-18019619.1.0000.5149). A amostra foi recrutada dentre usuários da Faculdade de Odontologia da UFMG, de março a dezembro de 2019. Foram registrados: IGM, IPV, profundidade à sondagem (PS), sangramento à sondagem (SS), nível de inserção clínico (NIC), recessão gengival (RG), CGID, fluxo e volume do FCG e número de dentes presentes. O instrumento Oral Health Impact Profile (OHIP-14) foi aplicado para avaliar a Qualidade de Vida Relacionada à Saúde Bucal (QVRSB). O grupo controle incluiu pacientes sem doença sistêmica diagnosticada, pareados por sexo e idade. Os dados foram analisados pelo programa SPSS versão 25. Análises descritivas e comparativas foram realizadas usando os testes de Wilcoxon, Mann Whitney e Kruskal-Wallis seguido de Dunn-Bonferroni. Modelos de regressão logística binária condicional estimaram a Odds-Ratio, considerando como desfechos presença de periodontite e prevalência de alto impacto na QVRSB. Em todos os testes, o nível de significância de 5% foi adotado. As frequências de periodontite foram maiores em indivíduos em condição de transplante que no grupo controle, na fase pré-transplante e nos pacientes Tx-fígado. O diagnóstico mais frequentemente encontrado foi a periodontite estágio I localizada. As medianas de IPV, PS, NIC, volume e fluxo do FCG foram maiores em pacientes de transplante comparados aos controles (p<0,05). Comparados aos respectivos controles, os grupos Tx-fígado e Tx-rim apresentaram medianas de IPV e PS significativamente maiores. O número de dentes presentes foi menor no grupo Tx fígado que no Tx rim (p=0,027). No modelo ajustado final, nenhuma variável mostrou associação com a presença de periodontite (p>0,05). Pacientes de transplante tiveram pior percepção do impacto na QVRSB que os indivíduos controle (p=0,015). Os grupos TCTH (p=0,008) e Tx-fígado (p=0,033) foram mais impactados que seus controles. Na regressão logística, a variável transplante não afetou a frequência de alto impacto na QVRSB. No modelo final ajustado, a escolaridade e o número de dentes presentes permaneceram como fatores preditores do impacto da saúde bucal na qualidade de vida auto-relatada. Indivíduos com menor escolaridade (OR = 3,590; 1,021-12,622) e com menor número de dentes (OR = 4,991; IC95% 1,386-17,970) tiveram maior impacto na QVRSB. Concluiu-se, que as frequências de periodontite foram maiores em indivíduos em condição de transplante, na fase pré e em pacientes Tx-fígado. A periodontite estágio I localizada foi o diagnóstico mais frequente. A condição de transplante não afetou a presença de periodontite. O número de dentes presentes e a escolaridade tiveram impacto na QVRSB dos indivíduos em condição transplante, e estes demonstram uma pior percepção que os controles.


This cross-sectional observational study aimed to assess periodontal clinical parameters, modified gingival index (MGI), visible plaque index (VPI), drug-induced gingival overgrowth (DIGO), measuring gingival crevicular fluid (GCF) volume and flow , tooth loss as well as the impact of self-reported oral health on quality of life, in patients before and after hematopoietic stem cell (HSCT), liver (Tx-liver), kidney (Tx-kidney) transplantation compared to individuals without diagnosed systemic disease. The study was approved by the Research Ethics Committee of the Federal University of Minas Gerais (UFMG) (CAAE-18019619.1.0000.5149). The sample was recruited from users of the Faculty of Dentistry at UFMG, from March to December 2019. The outcomes MGI, VPI, probing depth (PD), bleeding on probing (BoP), clinical attachment level (CAL), gingival recession (GR), DIGO, flow and volume of GCF and number of teeth present were recorded. The Oral Health Impact Profile instrument (OHIP-14) was applied to assess the Oral Health Related Quality of Life (HRQoL). The control group included patients without diagnosed systemic disease, matched for sex and age. The data were analyzed using the SPSS software version 25. Descriptive and comparative analyzes were performed using the Wilcoxon, Mann-Whitney and KruskalWallis followed by Dunn-Bonferroni tests. To estimate the Odds-Ratio, conditional binary logistic regression models were used, considering as outcomes presence of periodontites and prevalence of hight impact on OHRQoL. In all tests, the significance level of 5% was adopted. The frequency of periodontitis was higher in individuals undergoing transplantation than in the control group, in the pre-transplant phase and in Tx-liver patients. The most frequently found diagnosis was localized stage I periodontitis. The medians of VPI, PD, CAL, GCF volume and flow were higher in transplant patients compared to controls (p <0.05). The Tx-liver and Tx-kidney groups had significantly higher VPI and PD medians than their respectives controls. Comparing the transplant groups, the number of teeth present was lower in Tx-liver than in Tx-kidney (p = 0.027). In the final adjusted model, no variable was associated with the presence of periodontitis (p> 0.05). Transplant patients had a worse perception of the impact on OHRQoL than control subjects (p = 0.015). The groups HSCT (p = 0.008) and Tx-liver (p = 0.033) were more impacted than their controls. In logistic regression, the transplant variable did not affect the frequency of high impact on OHRQoL. In the final adjusted model, schooling and the number of teeth present remained as predictors of the impact of oral health on self-reported quality of life. Individuals with less education (OR = 3.590; 1.021-12.622) and with fewer teeth (OR = 4.991; 95% CI 1.386-17.970) had a greater impact on HRQoL. It was concluded that the frequencies of periodontitis were higher in individuals in a transplant condition, in the pre-transplantation phase and in Tx-liver patients. Localized stage I periodontitis was the most frequent diagnosis. The transplant condition did not affect the presence of periodontitis. The number of teeth present and education had an impact on the HRQoL of transplantation individuals, and these demonstrate a worse perception than the controls.

ABSTRACT

Abstract Background: In the past 20 years, hematopoietic stem cell transplantation (HSCT) has been investigated as treatment for systemic sclerosis (SSc). The goal of HSCT is to eradicate the autoreactive immune system, which is replaced by a new immune repertoire with long-lasting regulation and tolerance to autoantigens. Here, we describe the clinical outcomes of severe and refractory SSc patients that underwent HSCT at a single Brazilian center. Patients and methods: This is a longitudinal and retrospective study, including 70 adult SSc patients, with an established diagnosis of SSc, and who underwent autologous HSCT from 2009 to 2016. The procedure included harvesting and cryopreservation of autologous hematopoietic progenitor cells, followed by administration of an immunoablative regimen and subsequent infusion of the previously collected cells. Patients were evaluated immediately before transplantation, at 6 months and then yearly until at least 5-years of post-transplantation follow-up. At each evaluation time point, patients underwent clinical examination, including modified Rodnan's skin score (mRSS) assessment, echocardiography, high-resolution computed tomography of the lungs and pulmonary function. Results: Median (range) age was 35.9 (19-59), with 57 (81.4%) female and median (range) non-Raynaud's disease duration of 2 (1-7) years. Before transplantation, 96% of the patients had diffuse skin involvement, 84.2%, interstitial lung disease and 67%, positive anti-topoisomerase I antibodies. Skin involvement significantly improved, with a decline in mRSS at all post-transplantation time points until at least 5-years of follow-up. When patients with pre-HSCT interstitial lung disease were analyzed, there was an improvement in pulmonary function (forced vital capacity and diffusing capacity of lung for carbon monoxide) over the 5-year follow-up. Overall survival was 81% and progression-free survival was 70.5% at 8-years after HSCT. Three patients died due to transplant-related toxicity, 9 patients died over follow-up due to disease reactivation and one patient died due to thrombotic thrombocytopenic purpura. Conclusions: Autologous hematopoietic progenitor cell transplantation improves skin and interstitial lung involvement. These results are in line with the international experience and support HSCT as a viable therapeutic alternative for patients with severe and progressive systemic sclerosis.(AU)

ABSTRACT

Post-transplantation cyclophosphamide (PT-Cy) alone or in combination with other immunosuppressive drugs has emerged as a promising strategy in the setting of allogeneic hematopoietic stem cell transplantation. Improved survival rate was reported in lymphoid malignancies following PT-Cy strategy compared with myeloid disease in non-myeloablative bone marrow transplant setting. Thus, we aimed to evaluate the safety and efficacy of PT-Cy combined with cyclosporine as graft-versus-host disease (GVHD) prophylaxis after myeloablative conditioning and T cell-replete peripheral stem cell transplantation in lymphoid malignancies. This single-arm phase II clinical trial (NCT01435447) involving 31 adult patients was conducted from January 2013 to June 2018. The donor-type neutrophil engraftment rate was 100%, and the overall incidence of grade II to IV and grade III to IV acute GVHD was 39% and 24%, respectively. The cumulative incidence rates of chronic GVHD (35%), including moderate to severe forms (10%), were reduced compared with those of the historical group (P = 0.03 and P = 0.04, respectively). With a median follow-up of 18 months, the estimated 2-year overall and event-free survival was 64.8% (95% confidence interval: 47.8%-86.7%) and 58.4% (95% CI: 41.9%-81.7%), respectively. The 2-year cumulative incidence rate of relapse was 19.5% (95% CI: 9.0%-35.8%), whereas the non-relapse mortality rate was 21.8% (95% CI: 11.3%-38.1%). These results demonstrated the feasibility of PT-Cy as GVHD prophylaxis in this clinical setting. This strategy could significantly reduce the incidence of chronic GVHD and its moderate to severe forms but not of acute GVHD and results in similar survival outcomes compared with the historical group. A prospective study with additional patients is warranted to confirm the role of PT-Cy in lymphoid malignancy.

ABSTRACT

A case of SNX10 gene mutation in a patient with infantile malignant osteopetrosis (IMO) was admitted to Department of Pediatrics, Third Xiangya Hospital, Central South University. The patient had the symptom of anemia, hepatosplenomegaly and growth retardation. The X-ray examination suggested extensive increase of bone density throughout the body, which was clinically diagnosed as IMO. The homozygous mutation of SNX10 gene c.61C>T was found via gene sequencing. We reviewed the relevant literatures and found that anemia, visual and hearing impairment, hepatosplenomegaly are the main clinical symptoms of IMO, SNX10 gene mutation is a rare cause of IMO, and hematopoietic stem cell transplantation is an effective treatment.

ABSTRACT

OBJECTIVE@#To investigate the clinical correlation of expression level changes of miR-181b and miR-194 to the pathogenesis of acute graft-versus-host disease (aGVHD), and determine plasma miR-181b and miR-194 as the potential biomarkers for aGVHD.@*METHODS@#The plasma samples were collected from 31 patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) at before HSCT, 15 days after HSCT and onset of aGVHD. The expression levels of miR-181b and miR-194 were detected by quantitative real-time PCR. Receiver-operating characteristic (ROC) curves and the area under the ROC curve (AUC) were used to assess the sensitivity and specificity of miRNA biomarkers for the diagnosis of aGVHD.@*RESULTS@#MiR-181b and miR-194 downregulated after treatment were significantly upregulated in the plasma at onset of aGVHD (P0.05). The expressions of plasma miR-181b and miR-194 collected on day 15 after HSCT were significantly upregulated in the patients with aGVHD in comparison with non-GVHD patients (P<0.05). Moreover, these elevated miRNAs were detected before aGVHD. The AUC of miR-181b predicting aGVHD was 0.91±0.05 (specificity was 0.94, sensitivity was 0.69). The AUC of miR-194 predicting aGVHD was 0.91±0.06 (specificity was 0.94, sensitivity was 0.77).@*CONCLUSION@#MiR-181b and miR-194 may serve as early biomarkers for the diagnosis and prognosis of aGVHD.

ABSTRACT

OBJECTIVE@#To investigate the clinical characteristics and risk factors of cytomegalovirus (CMV) infection after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with severe aplastic anemia (SAA).@*METHODS@#Clinical data from 270 SAA patients with allo-HSCT were retrospectively analyzed, including 108 sib congruence patients and 162 substitute donors (68 unrelated donor congruence patients and 94 related haploid patients). Different pretreatment schemes were selected for different transplantation modes. The HLA-identical sibling and haploid grafts were all bone marrow and peripheral blood stem cells, and the grafts from unrelated donors were peripheral blood stem cells. After granulocyte implantation, blood CMV-DNA was regularly monitored. Flow cytometry was also used to determine the absolute number of CD3@*RESULTS@#CMV infection occurred in 229 of 270 patients with an incidence of 84.8%. Among them, 18 patients developed giant cell disease. Univariate analysis showed that alternative donors (unrelated total and haploid donors), mycophenolate mofetil and acute graft-versus-host disease were statistically significantly associated with CMV infection (P<0.05). Multivariate analysis showed that alternative donors were associated with CMV infection. The recovery of CD3@*CONCLUSION@#After allo-HSCT, substitute donors are more easily to develop CMV infection than full-sibling donors, and the reconstruction of immune function is delayed after transplantation.

ABSTRACT

OBJECTIVE@#To investigate the correlation between pretransplant serum ferritin (SF) level and prolonged or prolonged isolated thrombocytopenia (PT) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).@*METHODS@#The clinical data of 35 patients with PT after allo-HSCT were retrospectively analyzed, and 35 patients were matched according to age and sex as a controls from 424 allo-HSCT patients with normal platelet count. The serum ferritin level before the transplantation was analyzed. The potential risk factors were analyzed by chi-square test and Fisher's exact test as well as univariate and multivariate logistic regression. The survival curve was estimated by the Kaplan-Meier model to explore its clinical significance. In addition, ROC curve was used to verify the predictive power of SF.@*RESULTS@#Compared with control group, the SF level in the PT group before transplantation significantly increased (P=0.001). Multivariate analysis results showed that SF level before transplantation was a risk factor for prolonged thrombocytopenia after HSCT, and patients with SF≥1000 ng / ml showed a higher risk of death (P=0.014). ROC curve showed that SF level could be used as a predictor of prolonged thrombocytopenia after allo-HSCT.@*CONCLUSION@#The SF level before allo-HSCT relates with occurrence and prognosis of PT in patients after allo-HSCT. Detection of SF level can provide guidance for the intervention of prolonged thrombocytopenia after HSCT.

ABSTRACT

OBJECTIVE@#To investigate the clinical characteristics and prognosis of patients with medium and high risk myelodysplastic syndrome (MDS).@*METHODS@#97 MDS patients above the age of 60 treated in Nanfang Hospital, Southern Medical University from February 2011 to August 2020 were enrolled. The clinical characteristics and prognosis of the MDS patients with medium risk, high risk or very high risk based on IPSS-R category were retrospectively analyzed. According to the difference of treatment regimes, the patients were divided into the transplantation group, chemotherapy group and other treatment group, and the efficacy among the patients in the 3 groups were analyzed.@*RESULTS@#MDS with excess blast (MDS-EB) in the elderly patients with medium and high risk MDS were the most common, 47.4% of the patients with abnormal chromosome karyotypes, and 23.7% with complex karyotypes (≥3). 97.3% of the patients showed at least one gene mutation, and TP53 mutations were detected in nearly 20% of the patients with medium and high risk. Multivariate analysis showed that IPSS-R category and treatment regimes were the factors affecting the prognosis of elderly patients with medium and high risk MDS. The median overall survival (OS) time of the patients in the 3 groups showed significant difference (P=0.012), and the median OS of the patients in the transplantation group was significantly longer than that in the chemotherapy group and other group (P=0.003,P=0.014,respectively), while there was no significant difference in median OS between chemotherapy group and other treatment group (P=0.685).@*CONCLUSION@#Elderly MDS patients with medium and high risk can benefit from allogeneic hematopoietic stem cell transplantation, which will prolong their OS.

ABSTRACT

OBJECTIVE@#To summarize the clinical and Laboratory characteristics of patients with multiple myeloma (MM) and analyze the prognostic factors.@*METHODS@#Two hundred MM patients were retrospectively analyzed for the following parameters, including peripheral blood, bone marrow morphology, cytogenetics, clinical staging, and response to the chemotherapy in order to summarize related factors affecting overall survival (OS). The prognostic factors were also analyzed.@*RESULTS@#200 patients with MM were divided into 3 groups according to bone marrow plasma cell percentage (BMPC%) in bone marrow smears: <10% group (74 cases, 37.0%), 10%-50% group (75 cases, 37.5%), >50% group (51 cases, 25.5%). Compared with the other two groups, patients in BMPC%<10% group were characterized by lower clinical staging levels, lower rates of 13q14 deletion and t(11;14) positive, better response to chemotherapy and favorable three-year OS rate. The univariate analysis showed that prognostic factors indicating favorable outcome as evaluated by OS included age≤55 years old, BMPC%<10%, WBC<7.5×10@*CONCLUSION@#The clinical characteristics are different among MM patients with different BMPC% in bone marrow smears at initial diagnosis, and prognostic analysis shows that the BMPC% in bone marrow smears has an effect on OS rate. BMPC% in bone marrow smears at initial diagnosis, age, WBC, Hb, response to the fourth chemotherapy are also the main factors impacting the prognosis of patients.
