The prevalence of apical periodontitis in patients prior to hematopoietic cell transplantation: a systematic review.

Objectives: This systematic review addressed the question: "What is the prevalence of apical periodontitis in patients prior to hematopoietic cell transplantation?" Materials and Methods: A systematic search was conducted in MEDLINE/PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Grey Literature Report. Eligibility criteria were based on the condition, content, and population strategy: the condition was the radiographic prevalence of apical periodontitis, the content comprised patients scheduled for hematopoietic stem cell transplantation, and the population consisted of adult and pediatric patients. The revised Risk of Bias in Nonrandomized Studies of Exposure tool was used to assess the quality of studies. The Grading Recommendations Assessments, Development, and Evaluation (GRADE) tool was used to assess the quality of evidence. Results: Eight studies were included in this review. The average number of patients with apical periodontitis was 15.65% (range, 2.1%-43.34%). One study was classified as having a very high risk of bias, 1 with a high risk of bias, and 6 with some concern for bias. GRADE analysis showed a very low certainty of evidence. Significant limitations concerning the absence of control over confounding variables were identified. Conclusions: With the caveat of the very low quality of evidence in the studies reviewed, there was a low to moderate prevalence of apical periodontitis in patients prior to undergoing hematopoietic cell transplantation.

Assessment of rehabilitation practices during hematopoietic stem cell transplantation in the United States: a survey.

Background: Rehabilitation therapy is important to treat physical and functional impairments that may occur in individuals receiving physically taxing, yet potentially curative hematopoietic stem cell transplants (HSCT). However, there is scarce data on how rehabilitation is delivered during HSCT in real-life setting. Our objective is to assess the rehabilitation practices for adult patients hospitalized for HSCT in the United States. Methods: A 48-question online survey with cancer centers with the top 10% HSCT volumes (per American registries). We obtained data on patient characteristics, rehabilitation therapy details (timing, indication, administering providers), physical function objective and subjective outcome measures, and therapy activity precautions. Results: Fourteen (out of 21) institutions were included. Rehabilitation therapy referrals occurred at admission for all patients at 35.7% of the centers for: functional decline (92.9%), fall risk (71.4%), and discharge planning (71.4%). Participating institutions had physical therapists (92.9%), occupational therapists (85.7%), speech language pathologists (64.3%) and therapy aides (35.7%) in their rehabilitation team. Approximately 71% of centers used objective functional measures including sit-to-stand tests (50.0%), balance measures (42.9%), and six-minute walk/gait speed (both 35.7%). Monitoring of blood counts to determine therapy modalities frequently occurred and therapies held for low platelet or hemoglobin values; but absolute neutrophil values were not a barrier to participate in resistance or aerobic therapies (42.9%). Discussion: Rehabilitation practices during HSCT varied among the largest volume cancer centers in the United States, but most centers provided skilled therapy, utilized objective, clinician and patient reported outcomes, and monitored blood counts for safety of therapy administration.

Survival After Hematopoietic Stem Cell Transplantation in Severe Combined Immunodeficiency (SCID): A Worldwide Review of the Prognostic Variables.

This study aims to perform an extensive review of the literature that evaluates various factors that affect the survival rates of patients with severe combined immunodeficiency (SCID) after hematopoietic stem cell transplantation (HSCT) in developed and developing countries. An extensive search of the literature was made in four different databases (PubMed, Embase, Scopus, and Web of Science). The search was carried out in December 2022 and updated in July 2023, and the terms such as "hematopoietic stem cell transplantation," "bone marrow transplant," "mortality," "opportunistic infections," and "survival" associated with "severe combined immunodeficiency" were sought based on the MeSH terms. The language of the articles was "English," and only articles published from 2000 onwards were selected. Twenty-three articles fulfilled the inclusion criteria for review and data extraction. The data collected corroborates that early HSCT, but above all, HSCT in patients without active infections, is related to better overall survival. The universal implementation of newborn screening for SCID will be a fundamental pillar for enabling most transplants to be carried out in this "ideal scenario" at an early age and free from infection. HSCT with an HLA-identical sibling donor is also associated with better survival rates, but this is the least common scenario. For this reason, transplantation with matched unrelated donors (MUD) and mismatched related donors (mMRD/Haploidentical) appear as alternatives. The results obtained with MUD are improving and show survival rates similar to those of MSD, as well as they do not require manipulation of the graft with expensive technologies. However, they still have high rates of complications after HSCT. Transplants with mMRD/Haplo are performed just in a few large centers because of the high costs of the technology to perform CD3/CD19 depletion and TCRαß/CD19 depletion or CD34 + selection techniques in vitro. The new possibility of in vivo T cell depletion using post-transplant cyclophosphamide could also be a viable alternative for performing mMRD transplants in centers that do not have this technology, especially in developing countries.

Assignment of the antibacterial potential of Ag2O/ZnO nanocomposite against MDR bacteria Proteus mirabilis and Salmonella typhi isolated from bone marrow transplant patients.

The rate of infectious diseases started to be one of the major mortality agents in the healthcare sector. Exposed to increased bacterial infection by antibiotic-resistant bacteria became one of the complications that occurred for bone marrow transplant patients. Nanotechnology may provide clinicians and patients with the key to overcoming multidrug-resistant bacteria. Therefore, this study was conducted to clarify the prevalence of MDR bacteria in bone marrow transplant recipients and the use of Ag2O/ZnO nanocomposites to treat participants of diarrhea brought on by MDR bacteria following bone marrow transplantation (BMT). Present results show that pathogenic bacteria were present in 100 of 195 stool samples from individuals who had diarrhea. Phenotypic, biochemical, and molecular analysis clarify that Proteus mirabilis and Salmonella typhi were detected in 21 and 25 samples, respectively. Successful synthesis of Ag2O/ZnO nanocomposites with a particle enables to inhibition of both pathogens. The maximum inhibitory impact was seen on Salmonella typhi. At low doses (10-5 g/l), it prevented the growth by 53.4%, while at higher concentrations (10-1 g/l), Salmonella typhi was inhibited by 95.5%. Regarding Proteus mirabilis, at (10-5 g/l) Ag2O/ZnO, it was inhabited by 78.7%, but at higher concentrations (10-1 g/l), it was inhibited the growth by 94.6%. Ag2O/ZnO nanocomposite was therefore found to be the most effective therapy for MDR-isolated bacteria and offered promise for the treatment of MDR bacterial infections that cause diarrhea.

History and legal aspects of bone marrow donor banks in Brazil

INTRODUCTION: Bone marrow transplants primarily depend on people who previously registered to be donors. From then on, the search for compatibility between donor and recipient begins. OBJECTIVE: To describe the historical landmarks and the legal apparatus of bone marrow donor banks in Brazil based on an integrative review. METHODS: LILACS database and PubMed and SciELO journals were used. The term bone marrow transplantation was the descriptor. Eligibility criteria were: articles with the theme of Bone Marrow Transplantation (BMT) and studies carried out on the national territory. RESULTS: A total of 88,855 articles were identified, among which 185 met the eligibility criteria. After they were thoroughly read, 14 articles were selected. The studies pointed out fragments that dealt with important historical landmarks for the establishment of bone marrow transplantation as a conventional treatment for oncohematological diseases. CONCLUSION: The use of BMT has a history of more than thirty years in Brazil. However, none of the articles identified specifically addresses the historical content of bone marrow transplantation.

Alterações na qualidade de vida de adultos com câncer hematológico em cinco anos após o transplante de células-tronco hematopoéticas / Changes in the quality of life of adults with hematological cancer in five years after hematopoietic stem cell transplantation

Resumo: O objetivo desta tese foi avaliar as alterações da qualidade de vida relacionada à saúde dos pacientes adultos com câncer hematológico, submetidos ao transplante de células-tronco hematopoéticas, nos primeiros cinco anos após o procedimento. Trata-se de um estudo quantitativo, longitudinal, observacional e analítico, realizado em hospital público do sul do Brasil, referência na América Latina para esta modalidade de tratamento. Foram incluídos 55 participantes com idade igual ou superior a 18 anos, que se submeteram a esta terapia. A coleta de dados ocorreu de setembro de 2013 a janeiro de 2021, com avaliações em dez etapas: pré-transplante (antes de iniciar o condicionamento), pancitopenia, pré-alta hospitalar, após 100 dias, após 180 dias, Follow up 1 (após 360 dias), e anualmente até completar cinco anos da realização do procedimento. Foram aplicados um instrumento para coleta de dados sociodemográficos e clínicos e os questionários de Qualidade de vida relacionada à saúde Quality of life Questionnaire Core 30 e Functional Assessment of Cancer Therapy - Bone Marrow Transplant, ambos traduzidos, adaptados e validados para o português - Brasil. Em relação ao diagnóstico, as leucemias estão presentes em 65% dos casos; quanto à modalidade de tratamento, o transplante de células-tronco alogênico foi realizado em 71% dos pacientes. No que diz respeito aos óbitos, a causa de maior incidência foi por recidiva da doença (44%), e o maior número ocorreu no primeiro ano (37%). A qualidade de vida global (56,6/100) e geral (90,7/148) apresentou os menores escores na etapa de pancitopenia, com melhores índices no quinto ano, (80,4/100) e (116,1/148), respectivamente. A análise com o modelo linear generalizado misto evidenciou alterações significativas nos escores dos domínios de qualidade de vida relacionada à saúde entre as etapas ao longo do tempo. Foi comprovada a hipótese de que os pacientes com melhores escores nos domínios de qualidade de vida relacionada à saúde observados no início do tratamento têm maior sobrevida. Os resultados do estudo inferem as correlações entre os domínios mensurados e encontram, assim, sustentação no modelo conceitual teórico utilizado. As contribuições consistem em reafirmar a dimensionalidade do constructo qualidade de vida relacionada à saúde, além de agregar conhecimento acerca das alterações autopercebidas pelos pacientes durante o tratamento.

Abstract: The objective of this thesis was to evaluate the changes in the health-related quality of life of adult patients with hematological cancer undergoing hematopoietic stem cell transplantation in the first five years after the procedure. This is a quantitative, longitudinal, observational and analytical study carried out in a public hospital in southern Brazil, a reference in Latin America for this treatment modality. We included 55 participants aged 18 years and over, who underwent this therapy. Data collection took place from September 2013 to January 2021, with evaluations in ten stages: pre-transplantation (before starting conditioning), pancytopenia, pre-hospital discharge, after 100 days, after 180 days, Follow up 1 ( after 360 days), and annually until completing five years of the procedure. An instrument for collecting sociodemographic and clinical data and the Health-related Quality of life Questionnaire Core 30 and Functional Assessment of Cancer Therapy - Bone Marrow Transplant questionnaires were applied, both translated, adapted and validated for Portuguese - Brazil. Regarding diagnosis, leukemias are present in 65% of cases; regarding the treatment modality, allogeneic stem cell transplantation was performed in 71% of the patients. With regard to deaths, the cause of highest incidence was disease recurrence (44%), and the highest number occurred in the first year (37%). The global (56.6/100) and general (90.7/148) quality of life had the lowest scores in the pancytopenia stage, with better rates in the fifth year (80.4/100) and (116.1/148), respectively. The analysis with the mixed generalized linear model showed significant changes in the scores of the health-related quality of life domains between the stages over time. The hypothesis was confirmed that patients with better scores in the domains of health-related quality of life observed at the beginning of treatment have greater survival. The study results infer the correlations between the measured domains and thus find support in the theoretical conceptual model used. The contributions consist of reaffirming the dimensionality of the health-related quality of life construct, in addition to adding knowledge about the self-perceived changes by patients during treatment.

Resumen: El objetivo de esta tesis fue evaluar los cambios en la calidad de vida relacionada con la salud de pacientes adultos con cáncer hematológico, sometidos a trasplante de células madre hematopoyéticas, en los primeros cinco años después del procedimiento. Se trata de un estudio cuantitativo, longitudinal, observacional y analítico realizado en un hospital público del sur de Brasil, referencia en América Latina para esta modalidad de tratamiento. Se incluyeron 55 participantes mayores de 18 años que se sometieron a esta terapia. La recolección de datos ocurrió de septiembre de 2013 a enero de 2021, con evaluaciones en diez etapas: pretrasplante (antes de iniciar el acondicionamiento), pancitopenia, alta prehospitalaria, después de 100 días, después de 180 días, Seguimiento 1 (después de 360 días), y anualmente hasta completar cinco años del procedimiento. Se aplicó un instrumento de recolección de datos sociodemográficos y clínicos y los cuestionarios Health-related Quality of life Questionnaire Core 30 y Functional Assessment of Cancer Therapy - Bone Marrow Transplant, ambos traducidos, adaptados y validados para portugués - Brasil. En cuanto al diagnóstico, las leucemias están presentes en el 65% de los casos; en cuanto a la modalidad de tratamiento, se realizó trasplante alogénico de células madre en el 71% de los pacientes. En cuanto a las defunciones, la causa de mayor incidencia fue la recidiva de la enfermedad (44%) y el mayor número se produjo en el primer año (37%). La calidad de vida global (56,6/100) y general (90,7/148) tuvieron las puntuaciones más bajas en la etapa de pancitopenia, con mejores tasas en el quinto año (80,4/100) y (116,1/148), respectivamente. El análisis con el modelo lineal generalizado mixto mostró cambios significativos en las puntuaciones de los dominios de calidad de vida relacionada con la salud entre las etapas a lo largo del tiempo. Se confirmó la hipótesis de que los pacientes con mejores puntajes en los dominios de calidad de vida relacionada con la salud observados al inicio del tratamiento tienen mayor sobrevida. Los resultados del estudio infieren las correlaciones entre los dominios medidos y así encuentran apoyo en el modelo teórico conceptual utilizado. Los aportes consisten en reafirmar la dimensionalidad del constructo calidad de vida relacionada con la salud, además de sumar conocimientos sobre los cambios autopercibidos por los pacientes durante el tratamiento.

Incidence and risk factors of adverse events in pediatric hemato-oncological patients: A cohort study.

BACKGROUND: Pediatric hemato-oncological (HO) patients are highly susceptible to the occurrence of adverse events (AE), nevertheless few research has been done in this field. Our aim was to describe the incidence, type, severity and preventability of AE in these patients, including bone marrow transplant (BMT) patients, and to identify patient's risk factors for having an AE. METHODS: Retrospective cohort study. Children under 18yo hospitalized at the HO or BMT ward in 2016 were eligible for the study. Type of AE, severity and preventability were described as absolute and relative frequencies. Cumulative incidence of patients with at least one AE (CI_AE) and the rate of occurrence of all AE were calculated. Risk factors (sex, recovery probability, comorbidities and being a BMT patient) were analyzed using logistic regression. RESULTS: 114 patients were included, 58% were male, average age was 8.7yo and 25 were BMT patients. 44 had at least one AE, with CI_AE of 38.6% (95%CI 29.7-47.5). Overall rate of occurrence of AE was 2.5 cases per 100 patients-day (95%CI 2.15-2.98). For BMT and non-BMT patients they were 2.8 (95%CI 2.2-3.6) and 2.5 (95%CI 1.98-3.1) respectively. Healthcare related infection was the most frequent AE. Most AE were moderate and with high preventability. Being a BMT patient was the only independent factor associated with the occurrence of at least one AE (OR=11.5, p<0.001). CONCLUSIONS: Our findings suggest that AE tend to be moderate and preventable in HO pediatric patients. BMT patients seem to be at greater risk of having an AE. Strategies focused on patient safety need to account for their specific characteristics.

As dimensões intangíveis da prática assistencial: biopolítica, ética e afeto em sua relação com a clínica / Intangible dimensions of care: biopolitics, ethics and affection in relation to clinical practice / Las dimensiones intangibles de la práctica asistencial: biopolítica, ética y afecto en su relación con la clínica

Este artigo é parte inicial de uma pesquisa realizada em um centro de transplante de medula óssea, do Sistema Único de Saúde (SUS), cujos usuários são pessoas em situação de extrema vulnerabilidade. Sua proposta é analisar dimensões que atravessam a prática em saúde e não se reduzem a resultados imediatamente mensuráveis, podendo ser chamadas de dimensões intangíveis do cuidar. O objetivo é refletir sobre o encontro profissional-paciente, em sua relação com o adoecimento e a morte, sob o conceito psicanalítico de inconsciente. Para isso, foi realizado o relato de situações vividas no campo denominadas vinhetas clínicas; e, com base nas articulações teóricas elaboradas, consideram-se os vetores da biopolítica, ética e afeto como axiais à assistência. Conclui com a necessidade de propor perspectivas do cuidar que reconheçam a subjetividade concernida à prática assistencial. (AU)

This article is based on the initial stages of a study undertaken in a public bone marrow transplant center for extremely vulnerable people. We analyze dimensions that cut across health care practice not reduced to immediately measureable results, otherwise called intangible dimensions of care. We reflect on the intersection between health professionals and patients in relation to illness and death drawing on the psychoanalytic concept of the unconscious. To this end, we document situations experienced in the field called clinical vignettes. Drawing on the theoretical framework, we consider the vectors biopolitics, ethics and affection to be core aspects of care. We conclude that there is a need for approaches to care that recognize the subjectivity of health care practice. (AU)

Dental Biofilm Microbiota Dysbiosis Is Associated With the Risk of Acute Graft-Versus-Host Disease After Allogeneic Hematopoietic Stem Cell Transplantation.

Acute graft-versus-host disease (aGVHD) is one of the major causes of death after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Recently, aGVHD onset was linked to intestinal microbiota (IM) dysbiosis. However, other bacterial-rich gastrointestinal sites, such as the mouth, which hosts several distinctive microbiotas, may also impact the risk of GVHD. The dental biofilm microbiota (DBM) is highly diverse and, like the IM, interacts with host cells and modulates immune homeostasis. We characterized changes in the DBM of patients during allo-HSCT and evaluated whether the DBM could be associated with the risk of aGVHD. DBM dysbiosis during allo-HSCT was marked by a gradual loss of bacterial diversity and changes in DBM genera composition, with commensal genera reductions and potentially pathogenic bacteria overgrowths. High Streptococcus and high Corynebacterium relative abundance at preconditioning were associated with a higher risk of aGVHD (67% vs. 33%; HR = 2.89, P = 0.04 and 73% vs. 37%; HR = 2.74, P = 0.04, respectively), while high Veillonella relative abundance was associated with a lower risk of aGVHD (27% vs. 73%; HR = 0.24, P < 0.01). Enterococcus faecalis bloom during allo-HSCT was observed in 17% of allo-HSCT recipients and was associated with a higher risk of aGVHD (100% vs. 40%; HR = 4.07, P < 0.001) and severe aGVHD (60% vs. 12%; HR = 6.82, P = 0.01). To the best of our knowledge, this is the first study demonstrating that DBM dysbiosis is associated with the aGVHD risk after allo-HSCT.

Carbapenem-resistant Serratia marcescens bloodstream infection in hematopoietic stem cell transplantation patients: Will it be the next challenge?

Surveillance programs have been reporting decreasing rates of carbapenem-sensitivity in Serratia marcescens, leading to a concern regarding the few remaining therapeutic options to treat these multidrug-resistant (MDR) organisms. Here, we describe a case series of 11 stem cell hematopoietic transplantation patients infected (N = 6) or colonized (N = 5) by carbapenem-resistant S marcescens (CrSm) from 2010 to 2013. The comorbidities found were acute renal insufficiency (3/11), neutropenia (7/11), and mucositis (8/11), and the mortality rate was 64%. KPC was the most prevalent carbapenemase detected (8/11) and tigecycline and gentamicin were the antimicrobials used as treatment.

Hemorrhagic cystitis and giant condyloma acuminatum of anus in a receptor of haploidentical hematopoietic transplant / Cistitis hemorrágica y condiloma acuminado gigante del ano en un receptor de trasplante hematopoyético haploidéntico

ABSTRACT Introduction: The reactivations of latent virus after bone marrow transplants affect the outcome of these patients. Hemorrhagic cystitis caused by BK virus, constitute a frequently lethal complication characterized by abdominal pain, hematuria and renal damage. The incidence is between 13-70 % in hematopoietic transplant receptors. The management includes antibiotics, antivirals, hyperhydration and forced diuresis, platelets and hyperbaric oxygen. Condyloma acuminatum of the anus associated to human papillomavirus is rare among transplanted patients (0.3-1.3 %). It is characterized by an invading mass in the region of the anus producing pain and bleeding. The treatment of choice is the surgical resection of the tumor. Objectives: To describe the clinical characteristics and evolution of hemorrhagic cystitis and anal condyloma acuminatum in a receptor of haploidentical hematopoietic transplant. Discussion: A 20-year-old man with diagnosis of acute myeloid leukemia, on day +21 post-transplant presented macroscopic hematuria associated to BK virus reactivation and resolved with hyperbaric oxygen. On day + 59 post-transplant, anal pain started and a perianal, cauliflower-like mass over 5 cm, was observed. He was diagnosed with condyloma acuminatum of the anus and surgical resection was successfully performed. Conclusions: We reported a unique case of concurrence of both, hemorrhagic cystitis and condyloma acuminatum of the anus after haploidentical hematopoietic transplant. The proper management of these two pathologies allowed a satisfactory evolution of the patient.

RESUMEN Introducción: La reactivación de virus latentes en el organismo después del trasplante de progenitores hematopoyéticos (TPH) afecta la evolución de estos pacientes. La cistitis hemorrágica por virus BK constituye una complicación frecuentemente mortal caracterizada por dolor suprapúbico, hematuria y daño renal. La incidencia varía entre 13 y 70 % de los receptores de trasplante hematopoyético. El tratamiento comprende el uso de antibióticos, antivirales, hidratación y diuresis forzada, plaquetas y oxígeno hiperbárico. El condiloma acuminado del ano asociado al virus del papiloma humano es extremadamente raro en pacientes trasplantados (0,3-1,3 %). Se caracteriza por una masa que invade la región del ano produciendo dolor y sangramiento. El tratamiento de elección consiste en la resección quirúrgica del tumor. Objetivos: Describir las características clínicas, el manejo y la evolución de cistitis hemorrágica y condiloma acuminado anal en un receptor de trasplante hematopoyético haploidéntico. Presentación del caso: Paciente de 20 años de edad con diagnóstico de leucemia mieloide aguda que en el día + 21 del trasplante comenzó con hematuria macroscópica asociada a virus BK que resolvió con oxígeno hiperbárico. En el día +59 comenzó con dolor anal y se observó una masa perianal en forma de coliflor de aproximadamente 5 cm. Se diagnosticó condiloma acuminado del ano y se realizó resección quirúrgica del tumor con todo éxito. Conclusiones: Se presenta un caso único donde concurren cistitis hemorrágica y condiloma acuminado del ano después del trasplante hematopoyético haploidéntico. El manejo apropiado de estas dos patologías condujo a la evolución satisfactoria del paciente.

Development of New White Fish Allergy after Bone Marrow Transplantation from a Non-atopic Donor.

Background: Transplant-acquired food allergy has become increasingly recognized in solid organ and bone marrow transplantation. As food allergy has no cure and causes considerable impact on the lives of patients who require strict avoidance of foods to avoid potentially severe or fatal reactions, it is crucial for physicians to better understand the risk factors and mechanisms driving development of food allergy post-transplant. We report a case of new food allergy to whitefish in an elderly patient post-bone marrow transplant in which neither donor nor recipient had a history of atopy. Methods: A 70-year-old man experienced an anaphylactic reaction to Swai whitefish (Pangasius hypophthalmus) 6 months post-transplant that he had previously tolerated on multiple occasions both pre-transplant and in the preceding months post-transplant. This allergy was investigated by commercial serum specific IgE testing and fresh prick-to-prick skin test to Swai whitefish. Results: Fresh prick-to-prick demonstrated large positive reaction to the Swai whitefish with wheal of 10 mm and flare of 22 mm compared to positive histamine control with a wheal/flare of 5x8mm. Serum specific IgE testing to commercial whitefish was negative (specific IgE <0.10kU/L). The patient continues to strictly avoid Swai whitefish but tolerates all other fish and shellfish. Conclusions: The unique development of specific Swai whitefish allergy in an elderly man after bone marrow transplant where both donor and recipient had no prior history of atopy strongly supports transplant-related immunomodulation as a major mechanism for transplant-acquired allergy and suggests that that absence of atopy or advanced age may not necessarily be protective.

Anemia aplásica en población pediátrica de Costa Rica: experiencia de 10 años / Aplastic anemia in Costa Rican pediatric population: a 10 year experience

Resumen Objetivo: La anemia aplásica es una enfermedad rara, potencialmente mortal sin diagnóstico y tratamiento temprano. El objetivo del estudio fue describir la epidemiología de la anemia aplásica en la población de 0 a 13 años a nivel nacional, atendida en el Hospital Nacional de Niños "Dr. Carlos Sáenz Herrera", de la Caja Costarricense de Seguro Social, único centro del país disponible para la atención en hematología pediátrica. Métodos: Se realizó un estudio observacional retrospectivo de los pacientes atendidos en el Servicio de Hematología Pediátrica, con diagnóstico de anemia aplásica adquirida y las diversas formas de aplasias congénitas, en el periodo de enero 2006 a junio de 2016. Se registró el tipo de tratamiento recibido, su respuesta y la mortalidad asociada con la enfermedad, así como algunos datos epidemiológicos. Resultados: Se analizó un total de 27 casos, 23 con anemia aplásica adquirida y 4 con diversos tipos de anemias congénitas. La edad media al momento del diagnóstico fue de 81,7 meses, con una relación hombre: mujer de 1.1:1. De los 23 pacientes con anemia aplásica adquirida, 10 recibieron tratamiento con globulina antitimocito y presentaron respuesta a la globulina equina 2/5 pacientes como primera línea de tratamiento y 1 como segunda línea; con la globulina de conejo se obtuvo respuesta en 1/5 pacientes como primera línea y en 2 como segunda línea. Tres pacientes recibieron tratamiento con trasplante de médula ósea y presentaron una respuesta completa, sin evidenciar datos de enfermedad de injerto versus huésped u otras complicaciones al finalizar el estudio. No se logró demostrar diferencia significativa respecto al sexo, edad de diagnóstico, valores del hemograma, frecuencia de requerimiento de plaquetas o glóbulos rojos, grado de severidad ni mortalidad. Conclusión: Se confirmó la baja prevalencia de la anemia aplásica; la muestra obtenida durante el periodo analizado es pequeña y limita la observación de características relevantes ante referentes internacionales.

Abstract Objective: Aplastic anemia is a rare and life-threatening disease without diagnosis and early treatment. The objective of this study was to describe the epidemiological characters of patients with aplastic anemia and 0-13 years old in Costa Rica, to treat in the Hospital Nacional de Niños Dr.Carlos Sáenz Herrera, CajaCostarricense de Seguro Social; only there offers Pediatric Hematology service. Methods: We performed an observational retrospective study, there including the patients diagnosed with both acquired aplastic anemia and inherited bone marrow failure syndromes from January 2006 to June 2016, regardless of sex or ethnicity. We evaluated the treatment received, the response to each treatment, and mortality associated with the disease. Results: An overall of 27 patients were included, 23 diagnosed with acquired aplastic anemia and, 4 with bone marrow failure syndrome. The mean age of diagnosis was 81.7 months, with a male to female ratio of 1.1:1. Of the 23 patients diagnosed with acquired aplastic anemia, 10 received immunosuppressive therapy with antithymocite globulin, with a response to horse globulin as a first line treatment in 2/5 patients, and 1 as a second line treatment. Patients with rabbit globulin showed to response in 1/5 cases when used as a first line treatment, and a response as a second line treatment after a no response treatment with horse globulin in 2/3 patients. Three patients treated with a matched related donor bone marrow transplant and showed complete response, without complications including graft versus host disease by the end of the study period. There was no statistical difference regarding sex, age of diagnosis, blood cell counts, frequency of blood product transfusions, degree of severity associated or, mortality. Conclusions: Our results confirm the low incidence of aplastic anemia, it's a little study population and has limited results of relevant characteristics and can´t compare with international studies.

Hepatitis B virus among hematopoietic stem cell transplant recipients: Antiviral impact in seroconversion, engraftment, and mortality in a Latin American center.

BACKGROUND: Hepatitis B virus (HBV) infection is a worldwide concern with a broad distribution. In immunosuppressed populations, such as solid organ and hematopoietic stem cell transplant (HSCT) recipients, it can reactivate leading to acute hepatic failure. Different risk factors are known for higher rates of reactivation, and entecavir, tenofovir, and lamivudine are often used for prophylaxis and treatment. However, data regarding the impact of antiviral drugs in neutrophil and platelet engraftment are still unknown and concern the management of viral hepatitis post-HSCT. METHODS: We performed a single-center, retrospective, observational study reviewing medical records of patients referred for hematopoietic stem cell transplant from 2010 to 2017, which were also HBV infected, aiming to describe outcomes related to antiviral treatment and also the impact on platelet and neutrophil recovery after transplant. A secondary goal consisted of analyzing the impact of HBV infection in early and late mortality post-HSCT. The study included patients with positive blood bank screening for hepatitis B infection (HBsAg, Anti-HBc or HBV-NAT), confirmed later on by a laboratory routine serology. RESULTS: A total of 1132 hematopoietic stem cell recipients were assessed between 2010 and 2017. Eighty-six patients were confirmed to have HBV infection, of which six were HBsAg-positive, 20 were isolated anti-HBc-positive, and 60 had resolved infection (anti-HBc-positive and anti-HBs-positive). With regard to prophylaxis, 19 patients underwent HSCT on HBV antiviral therapy or prophylaxis: two were HBeAg-positive, three were HBeAg-negative and HBV-DNA was only detectable in three of them. Moreover, one patient had an occult HBV infection. Regarding therapy, 9 patients were on entecavir, 6 patients on lamivudine, two on tenofovir, and two of them on a combination of tenofovir + lamivudine due to HIV co-infection. Reverse seroconversion was not identified in any patients receiving antiviral therapy or prophylaxis, but it was detected in one patient with occult hepatitis B and another with resolved infection. No severe side effects led to therapy discontinuation in the treated group, which also did not have any significant delay in neutrophil or platelet engraftment when compared to patients without antiviral therapy. In addition, the only factors associated with increased mortality were transplant onset after 50 years, allogeneic transplant and myeloablative conditioning regimens. Interestingly, the presence of HBsAg or detectable HBV-DNA was not related to worse outcomes, neither the use of rituximab. In multivariate analysis, the use of antiviral therapy, the occurrence of graft-versus-host disease or CMV reactivation also was not linked to increased mortality. CONCLUSIONS: To sum up, HBV serology, ALT, and HBV-DNA monitoring are essential to detect hepatic flares earlier, even in populations with chronic inactive hepatitis, due to the possibility of later seroconversion. HBV infection was not related to increased 2-year mortality post-transplant. Antiviral prophylaxis did not cause any important clinical or laboratory side effects that could demand discontinuation, and its use was not associated with later neutrophil and platelet engraftments.

O impacto do transplante de células-tronco hematopoiéticas na qualidade de vida dos pacientes / The impact of hematopoietic stem cell transplantation on patients' quality of life

Resumo: Os objetivos desta dissertação foram descrever o impacto do transplante de células tronco hematopoiéticas na qualidade de vida de pacientes transplantados e elaborar um vídeo com seus relatos, demonstrando as estratégias de enfrentamento da doença que possibilitaram melhorar sua qualidade de vida. Para sua estruturação procurou-se atender as recomendações do Consolidated Criteria for Reporting Qualitative Research, o que foi realizado em duas etapas: na primeira foi feita uma pesquisa qualitativa, descritiva e exploratória, com cinco participantes, de julho a agosto de 2017, em um hospital paranaense que é referência para este tipo de tratamento no Brasil. Os dados foram obtidos por meio de entrevista semiestruturada, autoaplicada em suas residências e em formato de vídeo, com questões sobre a vivência da terapêutica. E, em seguida, tratados com a técnica de Análise de Conteúdo. Após, foi realizada a edição para a composição de um vídeo. Os resultados demonstraram que, nesse estudo, a idade para o transplante de células-tronco hematopoiéticas dos participantes variou entre 21 e 52 anos, e houve a predominância de diagnósticos de leucemias e anemia aplásica severa. Emergiram cinco categorias: o impacto do adoecimento na descoberta da doença; as dificuldades do tratamento e alterações na qualidade de vida; a família como o primeiro suporte no enfrentamento da doença; espiritualidade e religiosidade como estratégias de enfrentamento, e a superação e o sentimento de gratidão. A presente pesquisa concluiu que os impactos na percepção da qualidade de vida se deram nos âmbitos familiar, social, emocional e físico. E as estratégias de enfrentamento que o estudo mostrou foram o amparo e o acolhimento da família, a religiosidade e a espiritualidade.

Abstract: The objectives of this dissertation were to describe the impact of hematopoietic stem cell transplantation on the quality of life of transplanted patients and to elaborate a video with their reports, demonstrating the overcoming strategies of the disease that enabled them to improve their quality of life. The purpose of this study was to meet the recommendations of the Consolidated Criteria for Reporting Qualitative Research, which was carried out in two stages: a qualitative, descriptive and exploratory study that was carried out with five participants from July to August 2017, in a hospital in Paraná considered a reference for this type of treatment in Brazil. The data were obtained through semi-structured interviews, self-applied in their homes and in video format, with questions about the experience of the therapy. And then selected and edited with the Content Analysis technique. Afterwards, editing was done for the composition of a video. The results showed that in the present study, the age for the transplantation of the hematopoietic stem cells of the participants ranged from 21 to 52 years old and there was a predominance of diagnoses of leukemia and severe aplastic anemia. Five categories emerged the impact of illness on the discovery of the disease; the difficulties of treatment and changes in quality of life; the family as the first support in coping with the disease; spirituality and religiosity as overcoming strategies, and the overcoming and feeling of gratitude. The present study concluded that the impacts on the perception of the quality of life occurred in the family, social, emotional and physical environments. And the coping strategies that the study showed were the shelter and shelter of the family, religiosity and spirituality.

What haematopoietic stem cell transplant patients think about health and oral care: A qualitative study in a Brazilian health service.

Differences in the perceptions of treatment between healthcare team and patients should be identified, aiming to provide a more humanised health care. We sought to understand and evaluate the concepts regarding oral health and dental care among haematopoietic stem cell transplant patients. Individual semi-structured interviews were conducted with patients, from both sexes, in the post-haematopoietic stem cell transplant stage, who underwent dental treatment. All interviews were recorded and transcribed, respecting the spelling and syntax used by the interviewees. A thematic content analysis was performed, and three themes were assessed: what is oral health, why was pre-transplant dental treatment performed, and what was the relevance of dental treatment for the haematopoietic stem cell transplant. Oral health was understood as the act of dental care through oral hygiene. The reason for performing prior dental treatment involves strict guidelines for transplants, and when questioned as to the importance of the dental treatment for transplants, the interviewed subjects' statements focused on the prevention of infections during the low-immunity stage. The individuals saw dental treatment as a step towards a successful transplant; their main concerns were not to re-establish their oral health, but rather to end the dental treatment as quickly as possible.

HLA analysis of Mexican candidates for bone marrow transplantation and probability of finding compatible related donors.

INTRODUCTION: Oncohematological disorders are the main cause of morbidity in the Mexican population from 1 to 19 years old, where megakaryoblastic and promyelocitic leukemias are more frequent. Considering that the success of a transplant is multifactorial, the criterion of compatibility in the HLA system is crucial and even more so when the source of HSC is bone marrow. OBJECTIVE: To determine the frequency of the HLA genotype in Mexican candidates who require a bone marrow transplant from related donors and the probability to find donors. MATERIALS AND METHODS: One hundred twenty-six candidates for bone marrow transplant and related donors were tested for HLA class I (-A*, -B* alleles) and class II (-DRB1* allele) in intermediate-resolution, as the first phase in the choice of the possible donor. The criteria to identify donors were determined by antigen-matched in each HLA haplotype as follows: 4/6, 5/6 and 6/6 at the HLA-A*, HLA-B*, and HLA-DRB1* alleles. RESULTS: Of all the candidates analyzed, 57.93%, at least one bone marrow donor was identified; in 53 cases, no donor was found. The average size of the families was 4.79 ±â€¯1.06 members. A higher percentage of compatibility with grade 6/6 (31.6%) was identified with brothers, followed by sisters in 25.3%. The probability to find at least one compatible potential donor was 1.51 ±â€¯0.92 donors. CONCLUSION: In the first phase to select donors, Mexican patients studied in this work, have a compatible donor, however the grade of resolution test influenced in the probability identified.
