    PURPOSE: This study was undertaken to test a daily Family Navigator Nurse (FNN) conducted intervention program, to support parents during the distressful experience of their child's Allogeneic Haematopoietic Stem Cell Transplantation (HSCT). METHODS: A qualitative analysis of the supportive...... intervention program for parents whose child is under HSCT treatment while hospitalized. Parents to 25 children were included in the intervention group. Twenty-five parents were included in a participant observational study and 21 of these completed a semi-structured interview 100 days following HSCT. RESULTS......: Three main problems faced by all parents included 1) the emotional strain of the child's HSCT; 2) re-organizing of the family's daily life to include hospitalization with the child; and 3) the financial strain of manoeuvring within the Danish welfare system. The FNN performed daily intervention rounds...

    For many patients, a hematopoietic stem cell transplant (HSCT) can be challenging to physical and emotional health. Supportive care needs can be overwhelming for many patients and families. The purpose of this study was to evaluate the effect of quality of life (QOL), spiritual well-being, and supportive care resources post-HSCT. This descriptive, repeated-measures study included people over the age of 18 years undergoing HSCT for any cancer diagnosis. The Functional Assessment in Cancer Therapy--Bone Marrow Transplant scale, the Functional Assessment of Chronic Illness Therapy--Spiritual--12 scale, and a resource questionnaire were administered prior to HSCT and following HSCT at 30, 60, 90, and 180 days. Three groups of HSCT patients were examined: allogeneic, autologous, and overall. Data analysis included descriptive statistics and correlations. In the sample (n = 159), the autologous HSCT group reported the highest QOL scores. Spirituality scores increased for the autologous HSCT group at 90 days, but decreased for the overall and allogeneic groups. The type of supportive care resources most used were information from the physician and nurse, the Leukemia and Lymphoma Society Support as the most used form of support group, and Faith, Prayer and Spiritual Healing. QOL and spiritual well-being scores correlated best at 180 days (6 months) for autologous and allogeneic patients.

    Full Text Available Background: Patients who undergo pediatric Hematopoietic Stem Cell Transplantation (HSCT may experience long-term psychological sequelae and poor Quality of Life (QoL in adulthood. This study aimed to investigate subjective illness experience, QoL, and psychopathology in young adults who have survived pediatric HSCT.Method: The study involved patients treated with HSCT in the Hematology-Oncology Department between 1984 and 2007. Psychopathology and QoL were investigated using the SCL-90-R and SF-36. Socio-demographic and medical information was also collected. Finally, participants were asked to write a brief composition about their experiences of illness and care. Qualitative analysis of the texts was performed using T-LAB, an instrument for text analysis that allows the user to highlight the occurrences and co-occurrences of lemma. Quantitative analyses were performed using non-parametric tests (Spearman correlations, Kruskal-Wallis and Mann-Whitney tests.Results: Twenty-one patients (9 males participated in the study. No significant distress was found on the SCL-90 Global Severity Index, but it was found on specific scales. On the SF-36, lower scores were reported on scales referring to bodily pain, general health, and physical and social functioning. All the measures were significantly (p < 0.05 associated with specific socio-demographic and medical variables (gender, type of pathology, type of HSCT, time elapsed between communication of the need to transplant and effective transplantation, and days of hospitalization. With regard to the narrative analyses, males focused on expressions related to the body and medical therapies, while females focused on people they met during treatment, family members, and donors. Low general health and treatment with autologous HSCT were associated with memories about chemotherapy, radiotherapy, and the body parts involved, while high general health was associated with expressions focused on gratitude (V

    Iron overload (IO) has been shown to be an important cause of mortality and morbidity in patients who underwent allogeneic hematopoietic stem cell transplantation (alloHSCT). This study aimed to evaluate the possible effect of oral iron-chelation treatment (deferasirox) on survival in alloHSCT recipients in the posttransplant period. A total of 80 alloHSCT recipients with IO were analyzed, retrospectively. Pretransplant and posttransplant data were obtained from the patients' files. Patients were divided into two groups. Group 1; patients who did not receive any chelator treatment due to side effects or compliance problems. These patients were treated by phlebotomy. Group 2 consisted of patients who received deferasirox treatment. The median treatment duration with deferasirox was 122 days (min-max:91-225). The iron chelating treatment significantly reduced serum ferritin levels administered at a dosage of 20-30 mg/kg/day (pdeferasirox (Exjade) treatment may improve survival in patients with iron overload who underwent alloHSCT.

    Voriconazole is a first-line agent for the prevention and treatment of a number of invasive fungal diseases. Relatively little is known about the relationship between drug exposure and the prevention of invasive fungal infections. A pharmacokinetic-pharmacodynamic substudy was performed as part of the BMT CTN 0101 trial, which was a randomized clinical trial comparing voriconazole with fluconazole for the prevention of invasive fungal infections in HSCT recipients. A previously described population pharmacokinetic model was used to calculate the maximum a posteriori Bayesian estimates for 187 patients. Drug exposure in each patient was quantified in terms of the average AUC and average trough concentrations. The relationship between drug exposure and the probability of breakthrough infection was investigated using logistic regression. AUC and trough concentrations in patients with and without breakthrough infection were compared. Pharmacokinetic data from each patient were readily described using the maximum a posteriori Bayesian estimates. There were only five patients that had a breakthrough infection while receiving voriconazole in the first 100 days post-HSCT. For these patients, there was no statistically significant relationship between the average AUC or average trough concentration and the probability of breakthrough infection [OR (95% CI) 1.026 (0.956-1.102) and 1.108 (0.475-2.581), respectively]. P value for these estimates was 0.474 and 0.813, respectively. Given the very small number of proven/probable infections, it was difficult to identify any differences in drug exposure in HSCT recipients with and without breakthrough fungal infections. © The Author 2016.

    Full Text Available Natural Killer cells (NK are lymphocytes with the potential to recognize and lyse cells which escaped T-cell mediated lysis due to their aberrant HLA expression profiles. Killer cell immunoglobulin-like receptors (KIR influence NK-cell activity by mediation of activating or inhibitory signals upon interaction with HLA-C (C1, C2 ligands. Therefore, absence of ligands for donor inhibitory KIRs following hematopoietic stem cell transplantation (HSCT may have an influence on its outcome. Previous studies showed that C1 negative patients have a decreased HSCT outcome.

    Full Text Available Abstract Background Allogeneic hematopoietic stem cell transplantation (HSCT, the most widely used potentially curable cellular immunotherapeutic approach in the treatment of hematological malignancies, is limited by life-threatening complications: graft versus host disease (GVHD and infections especially viral infections refractory to antiviral drugs. Adoptive transfer of virus-specific T cells is becoming an alternative treatment for infections following HSCT. We report here the results of a phase I/II multicenter study which includes a series of adenovirus-specific T cell (ADV-VST infusion either from the HSCT donor or from a third party haploidentical donor for patients transplanted with umbilical cord blood (UCB. Methods Fourteen patients were eligible and 11 patients received infusions of ADV-VST generated by interferon (IFN-γ-based immunomagnetic isolation from a leukapheresis from their original donor (42.9% or a third party haploidentical donor (57.1%. One patient resolved ADV infection before infusion, and ADV-VST could not reach release or infusion criteria for two patients. Two patients received cellular immunotherapy alone without antiviral drugs as a pre-emptive treatment. Results One patient with adenovirus infection and ten with adenovirus disease were infused with ADV-VST (mean 5.83 ± 8.23 × 103 CD3+IFN-γ+ cells/kg up to 9 months after transplantation. The 11 patients showed in vivo expansion of specific T cells up to 60 days post-infusion, associated with adenovirus load clearance in ten of the patients (91%. Neither de novo GVHD nor side effects were observed during the first month post-infusion, but GVHD reactivations occurred in three patients, irrespective of the type of leukapheresis donor. For two of these patients, GVHD reactivation was controlled by immunosuppressive treatment. Four patients died during follow-up, one due to refractory ADV disease. Conclusions Adoptive transfer of rapidly isolated ADV

    It appears from empirical studies that the problem-solving ability of patients is associated with the experience of distress and the patients' mental state. The goals of this study were the (1) conception and (2) associated evaluation of the psychological short-time intervention "problem-solving training" (PST) for patients hospitalized for hematopoietic stem cell transplantation (HSCT). (1) The conception of the PST comprised a multi-stage development phase. An existing manual for outpatients diagnosed with cancer was adapted to the specific situation of a HSCT. This was followed by development of a manual, definition of the general framework, instruction of coaches, and implementation in a hospital setting. (2) The associated evaluation of PST was conducted from the patients' and the coaches' point of view. A total of 22 patients and five coaches evaluated the training. The training was evaluated by both patients and coaches as being well achievable with the exception of a limited time frame for the first module. The manual explanations were judged to be intelligible by all participants. Regarding on-topic alertness, patients were, on average, rated as "rather "to "very attentive." The patients evaluated the response to their needs as "good." They further assessed their overall condition due to the training as "good." This study provides preliminary evidence for the feasibility of PST by using the developed manual (Psychological Short-Term Intervention PST for Patients During HSCT). Based on this, it is conceivable to implement this intervention in similar situations to the advantage of a different patient clientele.

    Patient registries, frequently referred to as outcome registries, are 'organized systems' that use observational study methods to collect uniform data. Registries are used to evaluate specified outcomes for a population defined by a particular disease, condition or exposure that serves one or more predetermined scientific, clinical or policy purposes. Outcome registries were established very early in the development of hematopoietic SCT (HSCT). Currently, myriads of national and international HSCT registries collect information about HSCT activities and outcomes. These registries have contributed significantly to determining trends, patterns, treatment practices and outcomes. There are many different HSCT registries, each with different aims and goals; some are led by professional organizations, others by government authorities, health care providers or third parties. Some registries simply assess activity and others study outcomes. These registries are complementary and are gradually developing interoperability with each other to expand future collaborative research activities. A key development in the last few years was the incorporation of recommendations into the World Health Organization guiding principles on cell, tissue and organ transplantation. The data collection and analysis should be an integral part of therapy and an obligation rather than a choice for transplant programs. This article examines challenges in ensuring data quality and functions of outcome registries, using HSCT registries as an example. It applies to all HSCT-related data, but is predominantly focused on HSCT registries of professional organizations.

    Full Text Available OBJECTIVE: The aim of this study was to document hematopoietic stem cell transplantation (HSCT activity and trends at our treatment center. METHODS: Data collected over a 10-year period were retrospectively analyzed, concentrating primarily on types of HSCT, transplant-related mortality (TRM, stem cell sources, indications for HSCT, and causes of death following HSCT. RESULTS: In total, 222 allogeneic (allo-HSCT (87.4% and 32 autologous (auto-HSCT (12.6% procedures were performed between 1998 and 2008. Stem cells obtained from unrelated donors were used in 22.6% (50/222 of the allo- HSCTs. Cord blood was the source of hematopoietic stem cells (HSC in 12.2% of all transplants. The most common indication for allo-HSCT was hemoglobinopathy (43.2%, versus neuroblastoma (53.1% for auto-HSCT. The TRM rate 1 year post transplantation was 18.3% ± 2.5% for all transplants, but differed according to transplantation type (23.5% ± 7.9% for auto-HSCT and 17.5% ± 2.6% for allo-HSCT. The most common cause of death 1 year post HSCT was infection (35.9%. CONCLUSION: The TRM rate in the patients that underwent allo-HSCT was similar to that which has been previously reported; however, the TRM rate in the patients that underwent auto-HSCT was higher than previously reported in developed countries. The selection of these patients to be transplanted must be made attentively.

    Post-hematopoietic stem cell transplantation (HSCT) chimerism monitoring is important to assess relapse and therapeutic intervention. The purpose of our study is to compare two methods variable number tandem repeats (VNTR) vs. quantitative real- time polymerase chain reaction (qPCR) in terms of determining chimerism. 127 (peripheral blood n=112, bone marrow n=15) samples were simultaneously tested by VNTR using APO-B, D1S80, D1S111, D17S30, gene loci SRY and ZP3 and qPCR using 34 assays (CA001-CA034) that are designed to a bi-allelic insertion/deletion (indel) polymorphism in the human genome. Samples were separated in three subsets: total WBC, T-cell and Myeloid cells. Extraction of DNA was performed then quantified. We analyzed column statistics, paired t-test and regression analysis for both methods. There was complete correlation between the two methods. The simplicity and rapidity of the test results from the qPCR method is more efficient and accurate to assess chimerism.

Central nervous system (CNS neurological complications, particularly brain hemorrhages, were the most common, followed by seizures and CNS infections. An unusual neurological complication was Wernicke's encephalopathy. Less frequent neurological complications were metabolic encephalopathy, neuroleptic malignant syndrome, reversible posterior leukoencephalopathy syndrome, brain infarct and movement disorders. The most common neurological complication of the peripheral nervous system was herpes zoster radiculopathy, while peripheral neuropathies, inflammatory myopathy and myotonia were very rarely found.Apresentamos as complicações neurológicas avaliadas em uma série de 1000 pacientes submetidos ao transplante de células tronco hematopoiéticas (TCTH. As complicações neurológicas do sistema nervoso central foram as mais encontradas, particularmente as hemorragias encefálicas, seguidas por crises convulsivas e por infecções. Uma complicação peculiar foi a encefalopatia de Wernicke. Menos freqüentemente foram encontrados casos de encefalopatia metabólica, síndrome maligna neuroléptica, leucoencefalopatia posterior reversível, infarto cerebral e os distúrbios do movimento. Entre as complicações neurológicas do sistema nervoso periférico a mais encontrada foi a radiculopatia pelo herpes zoster, enquanto que raramente se observaram casos de polineuropatias periféricas, miopatia inflamatória e de miotonia.

    The globally widespread single-gene disorders β-thalassemia and sickle cell anemia (SCA) can only be cured by allogeneic hematopoietic stem cell transplantation (HSCT). HSCT treatment of thalassemia has substantially improved over the last two decades, with advancements in preventive strategies, control of transplant-related complications, and preparative regimens. A risk class–based transplantation approach results in disease-free survival probabilities of 90%, 84%, and 78% for class 1, 2, and 3 thalassemia patients, respectively. Because of disease advancement, adult thalassemia patients have a higher risk for transplant-related toxicity and a 65% cure rate. Patients without matched donors could benefit from haploidentical mother-to-child transplantation. There is a high cure rate for children with SCA who receive HSCT following myeloablative conditioning protocols. Novel non-myeloablative transplantation protocols could make HSCT available to adult SCA patients who were previously excluded from allogeneic stem cell transplantation. PMID:22553502

    Full Text Available Abstract Background Optimal post-remission strategy for patients with acute myeloid leukemia (AML is matter of intense debate. Recent reports have shown stronger anti-leukemic activity but similar survival for allogeneic stem cell transplantation (allo-HSCT from matched sibling donor compared to autologous transplantation (auto-HSCT; however, there is scarcity of literature confronting auto-HSCT with allo-HSCT from unrelated donor (UD-HSCT, especially mismatched UD-HSCT. Methods We retrospectively compared outcome of allogeneic transplantation from matched (10/10 UD-HSCT or mismatched at a single HLA-locus unrelated donor (9/10 UD-HSCT to autologous transplantation in patients with AML in first complete remission (CR1. A total of 2879 patients were included; 1202 patients received auto-HSCT, 1302 10/10 UD-HSCT, and 375 9/10 UD-HSCT. A propensity score-weighted analysis was conducted to control for disease risk imbalances between the groups. Results Matched 10/10 UD-HSCT was associated with the best leukemia-free survival (10/10 UD-HSCT vs auto-HSCT: HR 0.7, p = 0.0016. Leukemia-free survival was not statistically different between auto-HSCT and 9/10 UD-HSCT (9/10 UD-HSCT vs auto-HSCT: HR 0.8, p = 0.2. Overall survival was similar across the groups (10/10 UD-HSCT vs auto-HSCT: HR 0.98, p = 0.84; 9/10 UD-HSCT vs auto-HSCT: HR 1.1, p = 0.49. Notably, in intermediate-risk patients, OS was significantly worse for 9/10 UD-HSCT (9/10 UD-HSCT vs auto-HSCT: HR 1.6, p = 0.049, while it did not differ between auto-HSCT and 10/10 UD-HSCT (HR 0.95, p = 0.88. In favorable risk patients, auto-HSCT resulted in 3-year LFS and OS rates of 59 and 78 %, respectively. Conclusions Our findings suggest that in AML patients in CR1 lacking an HLA-matched sibling donor, 10/10 UD-HSCT significantly improves LFS, but this advantage does not translate in better OS compared to auto-HSCT. In intermediate-risk patients lacking a fully HLA-matched donor

    Although new agents have been approved for the treatment of MDS, the only curative approach is allogeneic hematopoietic stem cell transplantation (HSCT) and thus, in particular circumstances this procedure has been proposed as a treatment option for low risk patients. We have retrospectively analyzed the results of HSCT in 291 patients from the Spanish MDS registry with special attention to low risk MDS (LR-MDS) in order to define the variables that could impact their clinical evolution after transplantation. At 2 years OS was 51% and EFS was 50% (95% CI 0.7-4.5 years for OS and 95% CI 0.1-3.9 years for EFS). Among 43 LR-MDS, transplant-related mortality was 28%. At 3 years, OS was 67% (95% CI 264.7-8927.2 days for OS) and EFS was 64% (95% CI 0-9697.2 days for EFS). In the multivariate analysis only cytogenetics retained statistical significant effect on both OS (p=.047) and EFS (p=.046). Conditioning regimen could improve outcome among this subset of patients (OS 86% and RFS 100% for patients receiving RIC regimen). The present study confirms that specific disease characteristic as well as transplant characteristics have a significant impact on transplant outcome. Regarding low risk patients a non-myeloablative conditioning would be preferable especially in cases without high-risk cytogenetics. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Allogeneic hematopoietic stem-cell transplantation (alloHSCT) is physically and psychosocially demanding. Among transplant recipients, adolescent and young adults (AYA) represent a special group, as disease occurs early in life, resulting in the prospect of long survival time and high burden of alloHSCT sequelae. However, data focusing on AYA undergoing alloHSCT are rare. Data resulting from a prospective multicenter trial initially focusing on graft-versus-host disease (GvHD) after alloHSCT were reused to analyse the differences between AYA and elderly patients. In total, data of 205 alloHSCT recipients were evaluated. Patients completed the FACT-BMT, HAP, SF-36, 24-AM, LOT-R, BSSS, HADS, and GvHD questionnaires. Median age of AYA and non-AYA patients was 29 and 52 years. Using 24-AM-Test, evaluating personality traits, non-AYA reported to be more conscientious (p = 0.033). However, AYA described higher quality of life regarding physical role functioning (p = 0.001), physical functioning (p = 0.002), bodily pain (p = 0.023), and emotional role function (p = 0.027) in the SF-36. General health perception, vitality, social role functioning, and mental health were comparable among both groups. On HAP scale, AYA reported higher maximum (p = 0.003) and adjusted activity scores (p = 0.002), but showed similar restrictions regarding activity, self-supply, and self-determination. AYA represent a particular group characterized by higher physical well-being and activity scores, and significantly vary from non-AYA patients in psychosocial aspects. Studies covering distinctive features of AYA undergoing alloHSCT are warranted to improve awareness of the special needs of this group.

    Full Text Available The selection of hematopoietic stem cell transplantation (HSCT donors includes a rigorous assessment of the availability and human leukocyte antigen (HLA match status of donors. HLA plays a critical role in HSCT, but its involvement in HSCT is constantly in flux because of changing technologies and variations in clinical transplantation results. The increased availability of HSCT through the use of HLA-mismatched related and unrelated donors is feasible with a more complete understanding of permissible HLA mismatches and the role of killer-cell immunoglobulin-like receptor (KIR genes in HSCT. The influence of nongenetic factors on the tolerability of HLA mismatching has recently become evident, demonstrating a need for the integration of both genetic and nongenetic variables in donor selection.

    Background and purpose: total-body irradiation (TBI) is a key part of the conditioning regimen before hematopoietic stem cell transplantation (HSCT). The exact role of TBI as part of the conditioning regimen is largely unclear. In order to determine the relevance of TBI, the status of TBI utilization was analyzed on the basis of a nationwide registry. Material and methods: 14,371 patients (1998-2002) documented in the German Stem Cell Transplantation Registry (DRST) were analyzed regarding TBI utilization prior to autologous or allogeneic transplantation, underlying disorder, type of donor, stem cell source, and size of the treatment center. Results: for autologous HSCT {proportional_to}10% of the patients (873/8,167) received TBI, with chronic lymphocytic leukemia (CLL, {proportional_to}80%, 171/214) and low-grade non-Hodgkin's lymphoma (l-NHL, {proportional_to}35%, 330/929) being the most important disorders. In the allogeneic setting 50% of the patients (2,399/4,904) received TBI, with acute lymphocytic leukemia (ALL, 85%, 794/930), acute myeloid leukemia (AML, 45%, 662/1,487) and chronic myeloid leukemia (CML, 49%, 561/1,156) being the key indications. The type of donor, stem cell source and center size did not strongly influence the use of TBI. Conclusion: TBI has only a limited role for the conditioning prior to autologous HCST. For allogeneic HSCT TBI is widely accepted with no major changes over the observation time. The use of TBI is generally accepted for ALL, whereas approximately half of the patients with CML or AML received TBI. Although a considerably large database was analyzed, no clear determinants for the use of TBI could be distinguished. (orig.)

    Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an autosomal recessive disorder caused by mutations in the gene encoding thymidine phosphorylase (TP). Allogeneic hematopoietic stem cell transplantation (HSCT) has been proposed as a treatment for patients with MNGIE and a standardized approach to HSCT in this condition has recently been developed. We report on the transplant course, management and short-term follow-up in two MNGIE patients who underwent HSCT. The source of stem cells was bone marrow taken from an HLA 9/10 allele-matched unrelated donor in the first patient and from an HLA 10/10 allele-matched sibling donor in the second. Both patients achieved full donor chimerism, and we observed restoration of buffy coat TP activity and lowered urine nucleoside concentrations in both of them. The post-transplant clinical follow-up showed improvement in gastrointestinal dysmotility, abdominal cramps and diarrhea. Neurological assessment remained unchanged. However, the first patient died 15 months after HSCT due to gastrointestinal obstruction and shock; the second patient died 8 months after the procedure due to respiratory distress following septic shock. Although HSCT corrects biochemical abnormalities and improves gastrointestinal symptoms, the procedure can be risky in subjects already in poor medical condition as are many MNGIE patients. Since transplant-related morbidity and mortality increases with progression of the disease and number of comorbidities, MNGIE patients should be submitted to HSCT when they are still relatively healthy, in order to minimize the complications of the procedure. Anyway, there is still incomplete knowledge on the natural history of the disease in many affected patients and it is not yet clear when the best time to do a transplant is. Further clues to the therapeutic potential of HSCT could result from a prolonged observation in a greater number of non-transplanted and transplanted patients, which would allow us

    Full Text Available Autologous hematopoietic stem cell transplantation (HSCT is the standard treatment for patients with relapsed and primary refractoryHodgkin's lymphoma (HL. According to current recommendations HSCT must be performed in first relapse or after registration of primary resistance disease. However, the HSCT in optimal time for all patients with HL who need it is impossible, due to insufficient capacity of national transplant centers. Analysis of the HSCT results from 369 HL patients treated in Russia and other CIS countries clinics showed that intensive long-term standard chemotherapy prior to transplantation is a poor prognostic factor regarding to mobilization efficacy, hematopoiesis recovery and late HSCT results. In this regard, to achieve best results HSCT must be performed no later than the second relapse or immediately after registrationof primary resistance disease. Treatment results in patients received a lot of chemotherapy before transplantation is worse. But they stillhave a chance for a cure and should be considered as potential candidates to HSCT if obtained sufficient graft quality and hematopoietic response to induction chemotherapy is achieved.

    Abstract Background Mucopolysaccharidosis type I (MPS I) is a lysosomal storage disorder that results in the accumulation of glycosaminoglycans causing progressive multi-organ dysfunction. Its clinical spectrum is very broad and varies from the severe Hurler phenotype (MPS I-H) which is characterized by early and progressive central nervous system (CNS) involvement to the attenuated Scheie phenotype (MPS I-S) with no CNS involvement. Indication, optimal timing, safety and efficacy of the two available treatment options for MPS I, enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation (HSCT), are subject to continuing debate. A European consensus procedure was organized to reach consensus about the use of these two treatment strategies. Methods A panel of specialists, including 8 specialists for metabolic disorders and 7 bone marrow transplant physicians, all with acknowledged expertise in MPS I, participated in a modified Delphi process to develop consensus-based statements on MPS I treatment. Fifteen MPS I case histories were used to initiate the discussion and to anchor decisions around either treatment mode. Before and at the meeting all experts gave their opinion on the cases (YES\\/NO transplantation) and reasons for their decisions were collected. A set of draft statements on MPS I treatment options composed by a planning committee were discussed and revised during the meeting until full consensus. Results Full consensus was reached on several important issues, including the following: 1) The preferred treatment for patients with MPS I-H diagnosed before age 2.5 yrs is HSCT; 2) In individual patients with an intermediate phenotype HSCT may be considered if there is a suitable donor. However, there are no data on efficacy of HSCT in patients with this phenotype; 3) All MPS I patients including those who have not been transplanted or whose graft has failed may benefit significantly from ERT; 4) ERT should be started at diagnosis and may be

    Full Text Available Immune reactions are among the most serious complications observed after hematopoietic stem cell transplantation (HSCT in children. Microarray technique allows for simultaneous assessment of expression of nearly all human genes. The objective of the study was to compare the whole genome expression in children before and after HSCT. A total of 33 children referred for HSCT were enrolled in the study. In 70% of the patients HSCT was performed for the treatment of neoplasms. Blood samples were obtained before HSCT and six months after the procedure. Subsequently, the whole genome expression was assessed in leukocytes using GeneChip Human Gene 1.0 ST microarray. The analysis of genomic profiles before and after HSCT revealed altered expression of 124 genes. Pathway enrichment analysis revealed upregulation of five pathways after HSCT: allograft rejection, graft-versus-host disease, type I diabetes mellitus, autoimmune thyroid disease, and viral myocarditis. The activation of those pathways seems to be related to immune reactions commonly observed after HSCT. Our results contribute to better understanding of the genomic background of the immunologic complications of HSCT.

    Beta thalassaemia major is a common hereditary haematological disease in southern Chinese. Advances in transfusion and iron chelation improve survival but haematopoietic stem cell transplantation (HSCT) is still the only curative treatment. Due to repeated blood transfusion and iron overload, thalassaemia patients undergoing HSCT are at a higher risk of graft rejection and transplant-related mortality. The prognostic factors identified to be affecting transplant outcome include hepatomegaly, hepatic fibrosis, and compliance to chelation therapy. Patients can be classified into three classes and conditioning regimens are modified according to the risk. Early stage patients have 85 to 90% chance of disease-free survival, whereas advance stage only has 60% disease-free survival. Mixed chimerism is common after HSCT but majority have satisfactory erythropoiesis without need for further transfusion. Sibling cord blood and bone marrow transplantation has similar outcome. Recently alternative donor transplant has been performed in patients without human leukocyte antigen (HLA)-identical siblings. The result of unrelated-donor bone marrow transplantation is in general inferior but extended HLA matching may improve outcome. The use of unrelated cord blood transplant from a single-centre study showed promising result. The survivors require iron depletion to remove excessive iron store and some may require hormonal replacement therapy. Most of the patients have good quality of life after successful HSCT.

    Relapse is the most frequent cause of treatment failure after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Natural killer (NK) cells and γδ T cells reconstitute early after allo-HSCT, contribute to tumor immunosurveillance via major histocompatibility complex-independent mechanisms and do not induce graft-versus-host disease. Here we performed a quantitative and qualitative analysis of the NK and γδ T cell repertoire in healthy individuals, recipients of HLA-matched sibling or unrelated donor allo-HSCT (MSD/MUD-HSCT) and umbilical cord blood-HSCT (UCB-HSCT). NK cells are present at high frequencies in all allo-HSCT recipients. Immune reconstitution (IR) of vδ2 +  cells depended on stem cell source. In MSD/MUD-HSCT recipients, vδ2 +  comprise up to 8% of the total lymphocyte pool, whereas vδ2 +  T cells are barely detectable in UCB-HSCT recipients. Vδ1 +  IR was driven by CMV reactivation and was comparable between MSD/MUD-HSCT and UCB-HSCT. Strategies to augment NK cell mediated tumor responses, similar to IL-15 and antibodies, also induced vδ2 +  T cell responses against a variety of different tumor targets. Vδ1 +  γδ T cells were induced less by these same stimuli. We also identified elevated expression of the checkpoint inhibitory molecule TIGIT (T cell Ig and ITIM domain), which is also observed on tumor-infiltrating lymphocytes and epidermal γδ T cells. Collectively, these data show multiple strategies that can result in a synergized NK and γδ T cell antitumor response. In the light of recent developments of low-toxicity allo-HSCT platforms, these interventions may contribute to the prevention of early relapse.

    Sclerotic chronic GvHD (cGvHD) is one of the most severe complications after allo-hematopoietic stem cell transplantation (HSCT). Risk factors associated with this complication remain not very well defined. With the aim to define a pre-transplantation risk profile, we have conducted a French retrospective analysis in 705 consecutive patients between 2005 and 2010. Analyses to determine pre-transplantation risk factors included as variables: patient and donor age, kind of donor, HLA matching, ABO matching, sex-matching, diagnosis, stem cell source, gender, GvHD prophylaxis and antithymocyte globulin (ATG) in the conditioning regimen. The cumulative incidence of sclerotic cGvHD was 18% (95% CI, 16.6-19.6) 3 years after onset of cGvHD. In univariate analysis, we found a significantly lower number of sclerotic cGvHD form in patients transplanted from cord blood cells (P=0.0021), in patients with a one mismatched donor (P=0.041) and in patients who had received ATG in the conditioning regimen (P=0.002). In multivariate analysis, factors associated with an increased risk of sclerotic cGvHD were young patient age, multiple myeloma and PBSC as the stem cell source. ATG in conditioning regimen and cord blood unit as the stem cell source were associated with a lower risk.

    2012-01-01

    Allogeneic hematopoietic stem cell transplantation (HSCT) remains the only truly effective curative treatment for refractory hematological malignancies. Unfortunately, relapse and transplant rejection continue to be of major concern. In order to enhance the effectiveness of the HSCT, various strategies have been explored to amplify the graft versus leukemia (GvL) effect. Cancer vaccines have emerged in recent years as a promising strategy for the immunotherapeutic treatment of cancer. Evidence shows that they are most likely to have the greatest effect in the setting of minimal residual disease and as adjuvant agents. With this in mind, researchers have begun to explore the use of cancer vaccines in conjunction with HSCT, with exciting results. There has also been recent work examining the effect of novel adjuvants or blockers of negative immune regulation to augment the effect of cancer vaccines in both the transplant and non-transplant settings. The addition of these agents may prove.

A prospective case-control study of 19 children with normal cardiac function undergoing autologous hematopoietic stem cell transplantation (HSCT) was performed. Tissue Doppler imaging (TDI) and echocardiographic measurements were obtained according to the guidelines of the American Society of Echocardiography before and 3 months after HSCT. Lateral mitral annulus before HSCT showed significant reduced mitral systolic annular velocity (P ICT) (P = 0.003) and IRT (P = 0.002) after HSCT, were observed. Investigation of lateral tricuspid annulus showed nearly similar results as the lateral mitral annulus. LV and RV Tei indices were higher before HSCT compared with control and remained high after HSCT. TDI detected subtle abnormalities in systolic and diastolic functions before and after HSCT, which suggests that a conditioning regimen may affect cardiac function. © 2015, Wiley Periodicals, Inc.

    Haploidentical hematopoietic stem cell transplantation (HSCT) is being increasingly used due to improvement of the transplantation procedures allowing a reduction of graft-versus-host-disease (GVHD) and of transplant-related mortality (TRM). Such improvements have been particularly observed after administration of T-replete HSCT graft associated to an in vivo T cell depletion by the administration of high-doses of cyclophosphamide (HD-Cy) after transplantation. Here, we have analyzed the results of haplo-identical T replete HSC transplants, in particular, when performed with post-transplant HD-Cy in order to provide recommendations for the clinical practice. Criteria of choice for a haploidentical donor by priority order are absence of donor-specific antibodies (DSA) and to prioritize: CMV seronegative recipient/donor couples, ABO matching in case of deserythrocytation, male donor for a male recipient, the youngest donor. There is no clear argument in favor of the use of bone marrow versus peripheral blood stem cells (PBSC) after non myeloablative conditioning regimen, while after ablative conditioning PBSC seem to be associated with higher risks of GVHD without obvious impact on survival. Results of haploidentical HSCT, confirmed by several groups, are interesting in lymphomas (in particular Hodgkin disease) and for acute leukemia. Outcomes of patients rely on age, disease status at transplant and conditioning intensity. At equivalent disease risk, results of haploidentical HSCT seem comparable to those of HLA matched HSCT, raising the question of the classification of such transplants as alternatives. In all cases, we recommend to include patients in prospective clinical trials. Copyright © 2016 Société Française du Cancer. Published by Elsevier Masson SAS. All rights reserved.

  3. Defective pulmonary innate immune responses post-stem cell transplantation; review and results from one model system

    Full Text Available Infectious pulmonary complications limit the success of hematopoietic stem cell transplantation (HSCT as a therapy for malignant and nonmalignant disorders. Susceptibility to pathogens in both autologous and allogeneic HSCT recipients persists despite successful immune reconstitution. As studying the causal effects of these immune defects in the human population can be limiting, a bone marrow transplant (BMT mouse model can be used to understand the defect in mounting a productive innate immune response post-transplantation. When syngeneic BMT is performed, this system allows the study of BMT-induced alterations in innate immune cell function that are independent of the confounding effects of immunosuppressive therapy and graft-versus-host disease. Studies from several laboratories, including our own show that pulmonary susceptibility to bacterial infections post-BMT are largely due to alterations in the lung alveolar macrophages. Changes in these cells post-BMT include cytokine and eicosanoid dysregulations, scavenger receptor alterations, changes in micro RNA profiles, and alterations in intracellular signaling molecules that limit bacterial phagocytosis and killing. The changes that occur highlight mechanisms that promote susceptibility to infections commonly afflicting HSCT recipients and provide insight into therapeutic targets that may improve patient outcomes post-HSCT.

    Full Text Available Abstract Background Invasive fungal infection (IFI is associated with high morbidity and high mortality in hematopoietic stem cell transplantation (HSCT patientsThe purpose of this study was to assess the characteristics and outcomes of HSCT patients with IFIs who are undergoing MV at a single institution in Taiwan. Methods We performed an observational retrospective analysis of IFIs in HSCT patients undergoing mechanical ventilation (MV in an intensive care unit (ICU from the year 2000 to 2009. The characteristics of these HSCT patients and risk factors related to IFIs were evaluated. The status of discharge, length of ICU stay, date of death and cause of death were also recorded. Results There were 326 HSCT patients at the Linkou Chang-Gung Memorial Hospital (Taipei, Taiwan during the study period. Sixty of these patients (18% were transferred to the ICU and placed on mechanical ventilators. A total of 20 of these 60 patients (33% had IFIs. Multivariate analysis indicated that independent risk factors for IFI were admission to an ICU more than 40 days after HSCT, graft versus host disease (GVHD, and high dose corticosteroid (p p = 0.676. Conclusion There was a high incidence of IFIs in HSCT patients requiring MV in the ICU in our study cohort. The independent risk factors for IFI are ICU admission more than 40 days after HSCT, GVHD, and use of high-dose corticosteroid.

    This study aimed to investigate the protective effects of magnesium isoglycyrrhizinate (MGL) on aspartate aminotransferase (AST), alanine aminotransferase (ALT), and serum levels of T helper 1 (Th1) cytokines in patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT). The study included 42 patients prepared for allo-HSCT, who were divided equally into MGL and reduced glutathione groups. The ALT and AST levels were detected 1day before pretreatment and transplantation, and 7, 14, and 21days after transplantation. The total days and times of fever, treatment time of patients in the laminar flow room, white blood cell (WBC) count, platelet (PTL) implantation time, and success rate of transplantation were recorded. The serum levels of Th1/Th2 cytokines were detected. MGL had a significant protective effect on AST 1day before transplantation and 7, 14, and 21days after transplantation, while ALT had a statistical difference only 7days after transplantation. MGL could shorten the duration of fever during transplantation and advance the WBC and PTL implantation time. Significant differences in Th1-like cytokines (P0.05) were found in the MGL group compared with the control group. MGL had significant protective effects on AST after transplantation. MGL could reduce the duration of fever during transplantation, help the reconstruction and recovery of WBCs and PTLs, and regulate Th1 cytokines, revealing its protective effects on hepatic transaminases and graft versus host disease in allo-HSCT patients.

    We determined whether assessment of the immunogenicity of individual donor-recipient HLA mismatches based on differences in their amino-acid sequence and physiochemical properties predicts clinical outcome following haematopoietic SCT (HSCT). We examined patients transplanted with 9/10 single HLA class I-mismatched grafts (n=171) and 10/10 HLA-A-, -B-, -C-, -DRB1- and -DQB1-matched grafts (n=168). A computer algorithm was used to determine the physiochemical disparity (electrostatic mismatch score (EMS) and hydrophobic mismatch score (HMS)) of mismatched HLA class I specificities in the graft-versus-host direction. Patients transplanted with HLA-mismatched grafts with high EMS/HMS had increased incidence of ⩾grade II acute GVHD (aGVHD) compared with patients transplanted with low EMS/HMS grafts; patients transplanted with low and medium EMS/HMS grafts had similar incidence of aGVHD to patients transplanted with 10/10 HLA-matched grafts. Mortality was higher following single HLA-mismatched HSCT but was not correlated with HLA physiochemical disparity. Assessment of donor-recipient HLA incompatibility based on physiochemical HLA disparity may enable better selection of HLA-mismatched donors in HSCT.

    Background Patients receiving high-dose chemotherapy and hematopoietic stem cell transplantation (HSCT) experience considerable reductions in physical activity and deterioration of their health status. Objective The purpose of this pilot study was to test the effects of strength training compared to usual activity on physical activity, muscle strength, fatigue, health status perceptions, and quality of life following HSCT. Interventions/Methods Nineteen subjects were randomized to the exercise or control group. Moderate intensity strength training began following discharge from the hospital. Dependent variables included physical activity, muscle strength, fatigue, health status perceptions and quality of life. Variables were measured prior to admission to the hospital for HSCT, day 8 following HSCT, and six weeks following discharge from the hospital. Results Significant time effects were noted for many variables with anticipated declines in physical activity, muscle strength, fatigue, and health status perceptions immediately after HSCT with subsequent improvements six weeks following hospital discharge. One group effect was noted with subjects in the exercise group reporting less fatigue than subjects in the control group. Although no significant interactions were detected, the trends suggest that the exercise group may be more physically active following the intervention compared to the usual activity group. Conclusions This study demonstrates the potential positive effects of strength training on physical activity, fatigue, and quality of life in people receiving high-dose chemotherapy and HSCT. Implications for Practice Preliminary evidence is provided for using strength training to enhance early recovery following HSCT. Elastic resistance bands are easy to use and relatively inexpensive.

    Vitamin D has emerged as a central player in the immune system, with its deficiency being implicated in the pathogenesis of several autoimmune diseases, including chronic GvHD. This is a retrospective cohort analysis of 166 patients, who underwent allogeneic hematopoietic stem cell transplantation (HSCT) at the Karolinska University Hospital, evaluating GvHD, graft failure, infectious complications and survival after HSCT in relation to pre-transplantation vitamin D levels. Most of the patients were deficient in vitamin D before HSCT (median 42 nmol/L). In multivariate analysis, vitamin D level before HSCT was identified as a significant independent risk factor for development of cGvHD. The increased incidence of cGvHD was not coupled to better disease-free survival; instead there was a trend towards lower overall survival in the vitamin D-deficient patients. In addition, we found a significant correlation between vitamin D deficiency and incidence of CMV disease, with no case of CMV disease occurring in patients with sufficient levels of vitamin D before HSCT. Our results support a role of vitamin D in immune tolerance following HSCT. These findings could be highly relevant for the care of HSCT patients, and prospective, randomized studies on the effect of vitamin D supplementation are therefore needed.

  11. Recent Developments in Cellular Immunotherapy for HSCT-associated Complications

    2016-11-01

    Full Text Available Allogeneic HSCT is associated with serious complications and improvement of the overall clinical outcome of patients with hematological malignancies is necessary. During the last decades, post-transplant donor-derived adoptive cellular immunotherapeutic strategies have been progressively developed for the treatment of graft versus host disease (GvHD, infectious complications, and tumor relapses. To date, the common challenge of all these cell-based approaches is their implementation for clinical application. Establishing an appropriate manufacturing process, to guarantee safe and effective therapeutics with simultaneous consideration of economic requirements is one of the most critical hurdles. In this review we will discuss the recent scientific findings, clinical experiences, and technological advances for cell processing, towards the application of MSC as a therapy for treatment of severe GvHD, virus-specific T cells for targeting life-threating infections, and of CAR-engineered T cells to treat relapsed leukemia.

    Full Text Available Purpose: In low- and middle-income countries with limited resources, the success of a hematopoietic stem-cell transplantation (HSCT program relies directly on its affordability while obtaining similar outcomes to developed regions. The objective of this study was to describe the experience of a tertiary/referral center in Mexico City performing HSCT with the subsidy of a nongovernmental organization (NGO. Patients and Methods: We performed a retrospective analysis including 146 patients who underwent HSCT at the National Institutes of Health Sciences and Nutrition Salvador Zubiran and were subsidized by the NGO Unidos. Results: Seventy-five patients (51% and 71 patients (49% underwent autologous and allogeneic HSCT, respectively. The median age was 30 years, 56% did not obtain a bachelor’s degree, 79% had a low socioeconomic level, and 75% were unemployed. None had any health coverage. According to the real patient out-of-pocket expense, the subsidy by Unidos corresponded to 88% and 72% in autologous and allogeneic HSCT, respectively. Conclusion: Our results highlight that undergoing an HSCT was feasible for vulnerable patients because of the subsidy of medications and chemotherapy by Unidos. Therefore, creating NGOs in developing countries is important to provide complex medical procedures, such as HSCT, at limited-resource centers to underserved populations while obtaining good outcomes.

    Spirituality has been linked to improved adjustment and functioning in individuals with cancer; however, its effect on quality of life following hematopoietic stem cell transplantation (HSCT) has not been well-studied. This study investigated changes in spirituality in hematologic cancer patients recovering from HSCT and relationships between spirituality and dimensions of quality of life following HSCT. Participants (N = 220) completed measures of two dimensions of spirituality (meaning/peace and religious faith), depression, anxiety, fatigue, pain, and physical and functional well-being prior to transplant and at 1-, 3-, 6-, and 12-months posttransplant. Meaning/peace declined at 1-month posttransplant and returned to pretransplant levels by 6-months posttransplant, and faith increased from pretransplant to 6-months posttransplant. Mixed-effects linear regression models indicated that greater pretransplant meaning/peace, but not religious faith, predicted less depression, anxiety, and fatigue, and better physical and functional well-being during the 12-months following transplant. The capacity to find meaning and peace may facilitate recovery following HSCT. Results suggest that spirituality may be a resilience factor that could be targeted to improve quality of life for HSCT recipients. (c) 2015 APA, all rights reserved).

    nutritional status before hematopoietic stem cell transplantation (HSCT) affects prognosis: better nourished patients have shorter time to engraftment, while malnutrition is associated with increase of mortality rates, complications, medical costs, poor quality of life and hospitalization stay. Furthermore, underweight patients have increased risk of death in the early post- HSCT period, and non-relapse mortality is greater for those who are extremely underweight, overweight and obese. Obesity is associated with treatment-related toxicity, higher incidence of grade II-IV acute graft-versus- host disease (GVHD), infections and mortality. The objective of this study was to investigate the nutritional status of patients undergoing HSCT between 2007-2013 in a private hospital, by calculating the body mass index (BMI), to verify the prevalence of any nutritional imbalances, especially obesity. in this retrospective study, based on medical records, we analyzed data from all patients with malignant and nonmalignant diseases who underwent HSCT from January 2007 to February 2014 in the Hematology- Oncology and Bone Marrow Transplantation Center at a large, tertiary referral center in Brazil. a total of 257 cases were treated in the period and analyzed, of which 79% were aged up to 65 years old. Among these, 56% were overweight or obese. We observed a higher prevalence of obesity in elderly patients (P underweight and more overweight and obesity rates in men and elderly patients undergoing HSCT. Copyright AULA MEDICA EDICIONES 2014.

    Full Text Available Hematopoietic cell transplantation (HCT is an accepted treatment for acute myeloid leukemia (AML in first remission, the treatment of choice for chronic myeloid leukemia (CML and high risk groups of ALL who relapse with conventional chemotherapy. We assessed results of HCT for pediatric leukemia in our center. A total of 92 children, 63 with diagnose of AML, 23 with ALL and 6 with CML received allogeneic transplantation from HLA full matched siblings (57.6% and autologous transplantation (42.4%. Source of hematopoietic cells were peripheral blood 83.7%, bone marrow 15.2% and cord blood 1.6%. The median transplanted nucleated cells were 6.4 ± 4.7 ×108 /Kg (body weight of patients and mononuclear cells were 5.5 ± 2.9×108/Kg. The most common conditioning regimens were cyclophosphamide + busulfan. Prophylaxis regimen for GVHD was cyclosporin ± methotrexate. GVHD occurred in 50 (54.3% patients. Eighty five of children had engraftment, 26 (28.6% relapsed and 57 (62% are alive. The most common cause of death was relapse (68.6%. Five years overall survival of patients with AML and ALL were 49% and 44% respectively and disease free survival of them were 52% and 49%. One year overall survival and disease free survival of CML was 57%. Overall survival increased with increasing age of patients at transplantation time (P = 0.06. Longer survival significantly related to earlier WBC and platelet recovery (P < 0.0001 and P = 0.006 respectively. Considering acceptable overall and disease free survival of patients after HCT, we concluded that is a good modality in treatment of leukemia of children.

    Although steady improvements to chemotherapeutic treatments has helped cure 80% of childhood acute lymphoblastic leukemia (ALL) cases, chemotherapy has proven to be less effective in treating the majority of adult patients, leaving allogeneic hematopoietic stem cell transplantation (allo-HSCT) as the primary adult treatment option. Nevertheless relapse are the leading cause of death following allo-HSCT. The genetic pathogenesis of relapse following allo-HSCT in Philadelphia chromosome- negative ALL (Ph− ALL) remains unexplored. We performed longitudinal whole-exome sequencing analysis in three adult patients with Ph− B-cell ALL (Ph− B-ALL) on samples collected from diagnosis to relapse after allo-HSCT. Based on these data, we performed target gene sequencing on 23 selected genes in 58 adult patients undergoing allo-HSCT with Ph− B-ALL. Our results revealed a significant enrichment of mutations in epigenetic regulators from relapsed samples, with recurrent somatic mutations in SETD2, CREBBP, KDM6A and NR3C1. The relapsed samples were also enriched in signaling factor mutations, including KRAS, PTPN21, MYC and USP54. Furthermore, we are the first to reveal the clonal evolution patterns during leukemia relapse after allo-HSCT. Cells present in relapsed specimens were genetically related to the diagnosed tumor, these cells therefore arose from either an existing subclone that was not eradicated by allo-HSCT therapy, or from the same progenitor that acquired new mutations. In some cases, however, it is possible that leukemia recurrence following allo-HSCT could result from a secondary malignancy with a distinct set of mutations. We identified novel genetic causes of leukemia relapse after allo-HSCT using the largest generated data set to date from adult patients with Ph− B-ALL. PMID:26527318

    Since its inception in the mid-twentieth century, the complication limiting the application and utility of allogeneic hematopoietic stem cell transplantation (allo-HSCT) to treat patients with hematopoietic cancer is the development of graft-versus-host disease (GVHD). Ironically, GVHD is induced by the cells (T lymphocytes) transplanted for the purpose of eliminating the malignancy. Damage ensuing to multiple tissues, e.g., skin, GI, liver, and others including the eye, provides the challenge of regulating systemic and organ-specific GVH responses. Because the immune system is also targeted by GVHD, this both: (a) impairs reconstitution of immunity post-transplant resulting in patient susceptibility to lethal infection and (b) markedly diminishes the individual's capacity to generate anti-cancer immunity--the raison d'etre for undergoing allo-HSCT. We hypothesize that deleting alloreactive T cells ex vivo using a new strategy involving antigen stimulation and alkylation will prevent systemic GVHD thereby providing a platform for the generation of anti-tumor immunity. Relapse also remains the major complication following autologous HSCT (auto-HSCT). While GVHD does not complicate auto-HSCT, its absence removes significant grant anti-tumor responses (GVL) and raises the challenge of generating rapid and effective anti-tumor immunity early post-transplant prior to immune reconstitution. We hypothesize that effective vaccine usage to stimulate tumor-specific T cells followed by their amplification using targeted IL-2 can be effective in both the autologous and allogeneic HSCT setting. Lastly, our findings support the notion that the ocular compartment can be locally targeted to regulate visual complications of GVHD which may involve both alloreactive and self-reactive (i.e., autoimmune) responses.

    Identification of biomarkers that assess posttransplant risk is needed to improve long-term outcomes following heart transplantation. The Clinical Trials in Organ Transplantation (CTOT)-05 protocol was an observational, multicenter, cohort study of 200 heart transplant recipients followed for the first posttransplant year. The primary endpoint was a composite of death, graft loss/retransplantation, biopsy-proven acute rejection (BPAR), and cardiac allograft vasculopathy (CAV) as defined by intravascular ultrasound (IVUS). We serially measured anti-HLA- and auto-antibodies, angiogenic proteins, peripheral blood allo-reactivity, and peripheral blood gene expression patterns. We correlated assay results and clinical characteristics with the composite endpoint and its components. The composite endpoint was associated with older donor allografts (p heart transplantation. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Objective: To analyze the clinical outcome of total body irradiation in hematopoiesis reconstruction after autologous and allogeneic hematopoietic stem cell transplantation. Methods: 35 patients received autologous hematopoietic stem cell transplantation (ASCT group) and 35 patients received allogeneic hematopoietic stem cell transplantation (Allo-HSCT group) were enrolled in this study. And their hematopoiesis reconstruction were observed and analyzed. Results: The recovery time of ANC were 14 and 16 d, respectively, and the recovery time of PLT were 23 and 27 d, respectively, the difference were not significant (P>0.05) in ASCT group and Allo-HSCT group. But for both group, hematopoiesis reconstruction were faster in peripheral blood stem cell transplant than those in bone marrow transplant (P<0.05). The recovery time of PLT with the patients of total body irradiation dose ≥ 10 Gy were longer than those of < 10 Gy. Conclusions: At the same doses, the clinical outcome of hematopoiesis reconstruction of ASCT is similar to that of Allo-HSCT. But the recovery time in peripheral blood stem cell transplantation is faster than that in bone marrow transplant. The recovery time of PLT has relation with the irradiation dose. (authors)

    Full Text Available Objective: Venous thromboembolism (VTE in children who undergo hematopoietic stem cell transplantation (HSCT has high morbidity. The aim of this study is to assess the incidence of VTE in allogeneic pediatric HSCT recipients and the contribution of pretransplant prothrombotic risk factors to thrombosis. Materials and Methods: We retrospectively evaluated 92 patients between April 2010 and November 2012 undergoing allogeneic HSCT who had completed 100 days post-HSCT. Before HSCT, coagulation profiles; acquired and inherited prothrombotic risk factors including FV G1691A (factor V Leiden, prothrombin G20210A, methylenetetrahydrofolate reductase (MTHFR C677T, and MTHFR A1298C mutations; and serum homocysteine and lipoprotein (a, plasma antithrombin III, protein C, and protein S levels were obtained from all patients. Results: In the screening of thrombophilia, 8 patients (9% were heterozygous for factor V Leiden, 5 (6% were homozygous for MTHFR 677TT, 12 (14% were homozygous for MTHFR 1298CC, and 2 (2% were heterozygous for prothrombin G20210A mutation. We observed VTE in 5 patients (5.4%; a prothrombotic risk factor was found in 3 out of these 5 patients, while 4 out of 5 patients had central venous catheters. It was determined there was no significant relationship between VTE and inherited prothrombotic risk factors. Conclusion: VTE after HSCT seems to be a low-frequency event that may be due to low-dose, low-molecular-weight heparin prophylaxis, and the role of inherited prothrombotic risk factors cannot be entirely excluded without a prospective study.

    Full Text Available Relapse is the main cause of treatment failure after nonmyeloablative haploidentical transplant (haplo-HSCT. In an attempt to reduce relapse, we have developed a myeloablative (MA haplo-HSCT approach utilizing posttransplant cyclophosphamide (PT/Cy and peripheral blood stem cells as the stem cell source. We summarize the results of two consecutive clinical trials, using a busulfan-based (n=20 and a TBI-based MA preparative regimen (n=30, and analyze a larger cohort of 64 patients receiving MA haplo-HSCT. All patients have engrafted with full donor chimerism and no late graft failures. Grade III-IV acute GVHD and moderate-severe chronic GVHD occurred in 23% and 30%, respectively. One-year NRM was 10%. Predicted three-year overall survival, disease-free survival, and relapse were 53%, 53%, and 26%, respectively, in all patients and 79%, 74%, and 9%, respectively, in patients with a low/intermediate disease risk index (DRI. In multivariate analysis, DRI was the most significant predictor of survival and relapse. Use of TBI (versus busulfan had no significant impact on survival but was associated with significantly less BK virus-associated hemorrhagic cystitis. We contrast our results with other published reports of MA haplo-HSCT PT/Cy in the literature and attempt to define the comparative utility of MA haplo-HSCT to other methods of transplantation.

    To assess the impact of allogeneic hematopoietic stem-cell transplantation (HSCT) from matched related donors (MRDs) and matched unrelated donors (MUDs) on outcome in high-risk patients with acute myeloid leukemia (AML) within a prospective multicenter treatment trial. Between 1998 and 2004, 844 patients (median age, 48 years; range, 16 to 62 years) with AML were enrolled onto protocol AMLHD98A that included a risk-adapted treatment strategy. High risk was defined by the presence of unfavorable cytogenetics and/or by no response to induction therapy. Two hundred sixty-seven (32%) of 844 patients were assigned to the high-risk group. Of these 267 patients, 51 patients (19%) achieved complete remission but had adverse cytogenetics, and 216 patients (81%) had no response to induction therapy. Allogeneic HSCT was actually performed in 162 (61%) of 267 high-risk patients, after a median time of 147 days after diagnosis. Graft sources were as follows: MRD (n = 62), MUD (n = 89), haploidentical donor (n = 10), and cord blood (n = 1). The 5-year overall survival rates were 6.5% (95% CI, 3.1% to 13.6%) for patients (n = 105) not proceeding to HSCT and 25.1% (95% CI, 19.1% to 33.0%; from date of transplantation) for patients (n = 162) receiving HSCT. Multivariable analysis including allogeneic HSCT as a time-dependent covariable revealed that allogeneic HSCT significantly improved outcome; there was no difference in outcome between allogeneic HSCT from MRD and MUD. Allogeneic HSCT in younger adults with high-risk AML has a significant beneficial impact on outcome, and allogeneic HSCT from MRD and MUD yields similar results.

    To retrospectively evaluate the outcome and toxicity of total lymphoid irradiation (TLI) based conditioning regimen for allogeneic hematopoietic stem cell transplantation (HSCT) in severe aplastic anemia (SAA) patients who experienced an engraftment failure from prior HSCT or were heavily transfused. Between 1995 and 2006, 20 SAA patients received TLI for conditioning of HSCT. All patients were multi-transfused or had long duration of disease. Fifteen (75%) patients had graft failure from prior HSCT. In 18 (90%) patients, the donors were human leukocyte antigen identical siblings. The stem cell source was the peripheral blood stem cell in 15 (75%) patients. The conditioning regimen was composed of antithymocyte globulin plus TLI with a median dose of 750 cGy in 1 fraction. The graft-versus-host disease (GVHD) prophylaxis used cyclosporine with methotrexate. With a median follow-up of 10.8 years, graft failures developed in 6 patients. Among them, 3 patients received their third HSCT to be engrafted finally. The Kaplan-Meier overall survival rate was 85.0% and 83.1% at 5 and 10 years, respectively. The incidence of acute and chronic GVHD was 20% and 20%, respectively. None of the patients have developed a malignancy after HSCT. In our study, TLI based conditioning in allogeneic HSCT was feasible with acceptable rates of GVHD in SAA patients who experienced graft failure from prior HSCT or was at a high risk of graft rejection. We achieved relatively better results of engraftment and survival with a long term follow-up.

    To investigate the correlation between age, degree of disturbances in dental development, and vertical growth of the face in children treated with hematopoietic stem cell transplantation (HSCT). 39 long-term survivors of HSCT performed in childhood and transplanted before the age of 12, at a mean age of 6.8±3.3 years. Panoramic and cephalometric radiographs were taken at a mean age of 16.2 years. For each patient two age- and sex-matched healthy controls were included. The area of three mandibular teeth was measured and a cephalometric analysis was performed. The mean area of the mandibular central incisor, first and second molar was significantly smaller in the HSCT group, and the vertical growth of the face was significantly reduced, especially in the lower third, compared to healthy controls. A statistically significant correlation between age at HSCT, degree of disturbances in dental development, and vertical growth of the face was found. Children subjected to pre-HSCT chemotherapy protocols had significantly more growth reduction in vertical craniofacial variables compared to children without pre-HSCT chemotherapy. Conditioning regimens including busulfan or total body irradiation had similar deleterious effects on tooth area reduction and craniofacial parameters. The younger the child is at HSCT, the greater the impairment in dental and vertical facial development. This supports the suggestion that the reduction in lower facial height found in SCT children mainly is a result of impaired dental development and that young age is a risk factor for more severe disturbances. © 2012 John Wiley & Sons A/S.

    Vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC) result from genetic and environmental factors. We present patients who had no history of atopic disorders before bone marrow transplantation (BMT) and who seem to have acquired VKC or AKC from their donors, who had atopic disorders. Observational case series. The patients in this study were part of a cohort of patients who had undergone allogeneic hemapoietic stem cell transplantation (HSCT) from January 1997 through December 2007. Of 621 HSCT recipients, four recipients who were free of allergic disorders acquired VKC or AKC from their afflicted donors after HSCT. Each patient underwent complete ophthalmologic examination, determination of the total serum immunoglobulin (Ig) E, and conjunctival scrapings. Four (0.64%) of 621 patients who had undergone HSCT acquired VKC or AKC after BMT. The donors had VKC or atopic dermatitis. In addition, in two of these four patients, asthma developed. One patient had elevated total serum IgE. Conjunctival scrapings of all four patients revealed the presence of eosinophils. One patient had concurrent graft-versus-host disease. VKC and AKC are systemic allergic disorders characterized by local ocular manifestations. This report suggests the possibility of the acquisition of VKC or AKC after BMT by adoptive transfer.

    Full Text Available Traditionally, the concern of fatal complication is a major obstacle to transfer patients with unfavorable course of Hodgkin’s lymphoma tonational transplantation centers. Early mortality after high-dose chemotherapy with autologous hematopoietic stem cell transplantation(HSCT in the Russia, Ukraine and Belarus was assessed in this retrospective multicenter study.Patients and methods. The study included 372 patients with unfavorable course of Hodgkin’s lymphoma received HSCT between 01.1990and 06.2013: 35.5 % patients with primary resistance, 30.6 % with early relapse, 33.1 % with late relapse and 0.8 % during consolidation offirst complete remission.Results. During first 100 days after HSCT died 14 (3.8 % patients, during first year – 31 (8.4 % patients. During the study period a significant decrease in the 100-day and 1-year mortality rate was observed (p < 0.0001 for both. Among patients received HSCT in 1990–1995, 1996–2000, 2001–2005 and 2006–2013 the 100-day mortality was 19.4 %, 6.3 %, 1.1 % and 0.6 %, respectively. 1-year mortality for the same intervals was 32.3 %, 14.7 %, 4.5 % and 1.9 %, respectively.Conclusions. Currently HSCT in patients with unfavorable course of Hodgkin's lymphoma in national transplant centers, accompanied by an extremely low risk of fatal toxicity.

    Survival in patients with cystic fibrosis (CF) has improved dramatically over the past 30 to 40 years, with mean survival now approximately 40 years. Nonetheless, progressive respiratory insufficiency remains the major cause of mortality in CF patients, and lung transplantation (LT) is eventually required. Timing of listing for LT is critical, because up to 25 to 41% of CF patients have died while awaiting LT. Globally, approximately 16.4% of lung transplants are performed in adults with CF. Survival rates for LT recipients with CF are superior to other indications, yet LT is associated with substantial morbidity and mortality (~50% at 5-year survival rates). Myriad complications of LT include allograft failure (acute or chronic), opportunistic infections, and complications of chronic immunosuppressive medications (including malignancy). Determining which patients are candidates for LT is difficult, and survival benefit remains uncertain. In this review, we discuss when LT should be considered, criteria for identifying candidates, contraindications to LT, results post-LT, and specific complications that may be associated with LT. Infectious complications that may complicate CF (particularly Burkholderia cepacia spp., opportunistic fungi, and nontuberculous mycobacteria) are discussed. PMID:25826595

    Lymphoproliferative disease (LPD) is a complication of congenital and acquired immunodeficiency states. There are a number of treatment options for LPD arising after haematopoietic stem cell or solid organ transplantation including reduction of immunosuppression, targeted therapies, such as the anti-CD20 monoclonal antibody, rituximab, and EBV specific cytotoxic lymphocytes. Treatment of LPD in children with congenital immunodeficiency syndromes remains unsatisfactory and is associated with a high mortality rate. We recently managed an infant found to have polymorphic LPD concurrent with X-linked severe combined immunodeficiency (SCID). Haematopoietic stem cell transplantation (HSCT) had to be deferred because of progressive LPD. Treatment with rituximab resulted in regression of the LPD following which the patient received a 5/6 HLA matched umbilical cord blood (UCB) transplant. The patient remains well 20 months following transplantation. Rituximab treatment may have a useful role in the control of LPD associated with congenital immunodeficiency prior to HSCT.

    Full Text Available ABSTRACT Hematopoietic stem cell transplantation (HSCT is the only available treatment for the neurological involvement of disorders such as late-onset metachromatic leukodystrophy (MLD, mucopolysaccharidosis type I-Hurler (MPS-IH, and X-linked cerebral adrenoleukodystrophy (CALD. Objective To describe survival and neurological outcomes after HSCT for these disorders. Methods Seven CALD, 2 MLD and 2 MPS-IH patients underwent HSCT between 2007 and 2014. Neurological examinations, magnetic resonance imaging, molecular and biochemical studies were obtained at baseline and repeated when appropriated. Results Favorable outcomes were obtained with 4/5 related and 3/6 unrelated donors. Two patients died from procedure-related complications. Nine transplanted patients were alive after a median of 3.7 years: neurological stabilization was obtained in 5/6 CALD, 1/2 MLD, and one MPS-IH patient. Brain lesions of the MPS-IH patient were reduced four years after HSCT. Conclusion Good outcomes were obtained when HSCT was performed before adulthood, early in the clinical course, and/or from a related donor.

    To compare the differences between hematopoietic reconstitution and longterm prognosis of patients with severe aplastic anemia (SAA) after HLA- matched sibling donor hematopoietic stem cell transplantation(MSD-HSCT), Haploidentical HSCT(Haplo-HSCT), unrelated donor allogeneic HSCT(UD-HSCT)and umbilical cord blood HSCT(UCB-HSCT). In this retrospective study, 63 patients with SAA who received HSCT in the First Affiliated Hospital of Soochow University between May 2008 and December 2013 were enrolled. The subjects were divided into 4 groups according to the transplantation types. The hematopoietic reconstitution, the incidence of acute graft-versushost disease(aGVHD)and 5- year survival rate after transplantation were compared. All 53 subjects who received MSD-HSCT, Haplo-HSCT and UD-HSCT achieved hematopoietic reconstitution. Of them, the recovery of neutrophil and platelet were not significantly different(P0.05). MSD-HSCT, Haplo-HSCT and UD-HSCT had no statistically significance in terms of hematopoietic reconstitution or prognosis. Although hematopoietic reconstitution of UCB-HSCT was lower than other transplantation types, but no significant difference in overall prognosis. So if HLA-matched sibling donor is not available, SAA patients can choose Haplo- HSCT, UD - HSCT or UCB- HSCT with comparable efficacy to MSD- HSCT, as an alternative therapy.

    Full Text Available Purpose : The survival rate for childhood acute lymphoblastic leukemia (ALL has improved significantly. However, overall prognosis for the 20 to 25% of patients who relapse is poor, and allogeneic hematopoietic stem cell transplantation (HSCT offers the best chance for cure. In this study, we identified significant prognostic variables by analyzing the outcomes of allogeneic HSCT in ALL patients in second complete remission (CR. Methods : Fifty-three ALL patients (42 men, 79% who received HSCT in second CR from August 1991 to February 2009 were included (26 sibling donor HSCTs, 49%; 42 bone marrow transplantations, 79%. Study endpoints included cumulative incidence of acute and chronic graft-versus-host disease (GVHD, relapse, 1-year transplant-related mortality (TRM, disease-free survival (DFS, and overall survival (OS. Results : Cumulative incidences of acute GVHD (grade 2 or above and chronic GVHD were 45.3% and 28.5%, respectively. The estimated 5-year DFS and OS for the cohort was 45.2¡?#?.8%; and 48.3¡?#?%,; respectively. Only donor type, i.e., sibling versus unrelated, showed significant correlation with DFS in multivariate analysis (P=0.010. The rates of relapse and 1 year TRM were 28.9¡?#?.4%; and 26.4¡?#?.1%;, respectively, and unrelated donor HSCT (P=0.002 and HLA mismatch (P =0.022 were significantly correlated with increased TRM in univariate analysis. Conclusion : In this single institution study spanning more than 17 years, sibling donor HSCT was the only factor predicting a favorable result in multivariate analysis, possibly due to increased TRM resulting from unrelated donor HSCT.

    Allogeneic hematopoietic stem cell transplantation (HSCT) is a routine clinical procedure performed to treat patients with haematological malignancies, primary immune deficiencies or metabolic disorders. Infections during lymphopenia after allogeneic HSCT are associated with high mortality and morbidity. Typical infectious agents are Epstein-Barr virus, cytomegalovirus, herpes simplex virus, varicella-zoster virus and fungi. The study aim was to evaluate whether measurement of the responses of antigen-specific T-cells, recognizing infectious pathogens would correlate to protective functions in the stem cell recipient post-transplant. Twenty-one grafts were analysed by flow cytometry and cells were stimulated in vitro with relevant infectious antigens, followed by evaluation of T-cell proliferation and cytokine production. Results were compared to the recipients' clinical records 1-year post-transplantation. We show that an extensive repertoire of transferred antigen-specific T-cells from allogeneic donor grafts against infectious agents, involved in post-transplant infections, are linked to an absence of infectious complications for the recipient up-to 1-year post-transplant. The protective effect was associated with antigen-specific T-cell proliferation and IL-1β secretion. Our results suggest that assaying T-cell function before HSCT could determine individual risks for infectious complications and thus aid in clinical decision-making regarding prophylactic and pre-emptive anti-infective therapy. © 2017 International Society of Blood Transfusion.

    Hematopoietic stem cell transplantation (HSCT) activity was surveyed in the 9 countries in the WHO Eastern Mediterranean (EM) region that are reported to carry out transplants. Between the years of 1984 and 2007, 7933 transplants were reported. The total number of HSCT per year has continued to increase, with a plateau in allogeneic HSCT (allo-HSCT) between 2005 and 2007. Overall, a greater proportion of transplants were allogeneic HSCT (allo-HSCT) (n=5761, 77%) compared to autologous HSCT (ASCT) (n=2172, 23% ASCT). Of 5761 allo-HSCT, acute leukemia constituted the main indication (n=2124, 37%). There was a relatively high proportion of allo-HSCT for bone marrow failure (n=1001, 17%) and hemoglobinopathies (n=885, 15%). The rate of unrelated donor transplants remained low, with only 2 non-umbilical cord matched unrelated donor (MUD) allo-HSCT reported. One hundred umbilical cord (UCB) transplants were reported (0.017% of allo- HSCT). Peripheral blood stem cells (PBSC) were the main source of graft in allo-HSCT, and PBSCT increasingly constitutes the main source of stem cells. Reduced intensity conditioning was utilized in 5.7% of allografts over the surveyed period. ASCT numbers continue to increase. There has been a shift in the indication for ASCT from acute leukemia to lymphoproliferative disorders (45%) followed by myeloma (26%). The survey reflects transplantation activity according to the unique health settings of this region. Notable differences in transplant practices as reported to the European Group for Blood and Marrow Transplantation (EBMT) over recent years are addressed. PMID:21440654

    SOT may be indicated for a select group of pediatric patients who experience permanent organ failure following HSCT. However, there is limited information available about outcomes. We identified eight children at our center who received an SOT following an HSCT. Patients were six months to 18 yr at HSCT. Diseases for which children underwent HSCT included thalassemia, Wiskott-Aldrich syndrome, Shwachman-Diamond/bone marrow failure, sickle cell disease (SCD), erythropoietic porphyria (EP), ALL, chronic granulomatous disease, and neuroblastoma. Time from HSCT to SOT was 13 days to seven yr (median, 27 months. Lung SOT was performed for two patients with BO, kidney transplants for three patients, and liver transplants for three patients (VOD, chronic GVHD). Seven patients are alive with functioning allografts 6-180 months from SOT. Advances in organ procurement, operative technique, immunosuppressant therapy, and infection control may allow SOT for a select group of patients post-HSCT. However, scarcity of donor organs available in a timely fashion continues to be a limiting factor. Children who have undergone HSCT and develop single organ failure should be considered for an SOT if there is a high likelihood of cure of the primary disease. © 2010 John Wiley & Sons A/S.

    Mucositis developing as a result of myelo-ablative high dose therapy administered prior to hematopoietic stem cell transplantation (HSCT) is associated with the risk of bacteremia. The aim of the present study was to detect the pattern of bacteremia coinciding with the present practice of HSCT, to study the contribution of health-care associated infection (HAI) to the pattern of infection, in the context of the problem of antibiotic resistance in HSCT recipients. Patients and methods: This is a retrospective, single center study including patients who developed febrile neutropenia (FN) among HSCT recipients in one year duration. Results: Ninety FN episodes were recorded in 50 patients. Out of 39 positive blood cultures, Gram negative rods (GNR) were the predominant pathogens, constituting 67% (n =26) of isolated organisms, while 33% of infections were caused by gram positive cocci (GPC) (n= 13). Bacteremia was significantly associated with central venous line (CVL) infections and gastroenteritis (diarrhea and vomiting) with a p-value 0.024, 0.20 and 0.0001, respectively. Multi-drug resistant organisms (MDROs) were identified in 27 (69%) of the 39 positive blood cultures. Conclusion: In one year duration, gram negative pathogens were the predominant causes of infection in HSCT recipients with high rates of MDROs in our institution. Gastroenteritis and central venous line infections are the main sources of bacteremia

    Interferon-alpha (IFN) may have undesirable effects on a functioning graft. The aim of this study was to evaluate IFN treatment in kidney transplant candidates during the hemodialysis period as well as the results after transplantation. A total of 29 noncirrhotic hemodialysis patients with chronic hepatitis C virus (HCV) infection (based on long-term rise in ALT, HCV serology, HCV RNA by polymerase chain reaction methods, and histological evidence) were included. Tolerability to IFN treatment, pre- and posttransplantation therapeutic results, and long-term outcome were recorded. IFN regimen consisted of 3 million units (MU) times per week after hemodialysis sessions for 6 months, followed by 1.5 MU after each hemodialysis session for an additional 6 months. All patients gave informed consent for participation. IFN therapy was fairly well tolerated. Adverse effects due to IFN toxicity, renal disease, or causes related to the immunological properties of IFN were observed in 24% of patients. At the end of treatment, ALT had normalized in 23/28 patients (82.1%), and HCV RNA had cleared in 23/28 patients (82.1%). During follow-up, HCV RNA was persistently negative in 18 patients (64%, including transplant recipients). A total of 14 patients (nine HCV RNA-negative) received a kidney transplant. Mean follow-up after the procedure was 41 +/- 28 months. In all, 12 patients had a functioning graft, one had acute vascular rejection, and one died of carcinoma. All transplanted patients maintained normal ALT levels, and eight remained HCV RNA-negative. Treatment results in our study population were better than those observed in the general population. The long-term response achieved, which was maintained after transplantation, supports the use of IFN for HCV hepatitis in kidney transplant candidates under hemodialysis.

    Recent studies have demonstrated the protective effect of cytomegalovirus (CMV) reactivation against relapse after allogeneic hematopoietic stem cell transplantation (HSCT) for adult myeloid malignancies. We assessed the association of CMV reactivation, defined as the development of CMV antigenemia (at least 1 pp65 antigen-positive cell per 5.0 × 10(4) WBCs) within 100 days after HSCT, with the risk of relapse in 143 patients with pediatric acute leukemia. The median age at HSCT was 7 years, and underlying diseases included acute lymphoblastic leukemia in 101 patients and acute myeloid leukemia in 42. The cumulative incidence of CMV reactivation at day 100 after HSCT was 45.4%. At a median follow-up of 88 months, patients with CMV reactivation had significantly lower 5-year cumulative incidence of relapse compared with patients without CMV reactivation. In a multivariate analysis, high-level CMV reactivation (≥10 pp65 antigen-positive cells) was an independent factor associated with reduced relapse. However, CMV reactivation was also associated with higher nonrelapse mortality (NRM), mostly caused by opportunistic infection after grades II to IV acute graft-versus-host disease (GVHD), which resulted in decreased probability of survival. High-level CMV reactivation was a risk factor for increased NRM and worse overall survival in multivariate analysis. Although CMV reactivation may reduce the risk of relapse after HSCT for pediatric acute leukemia, effective management of severe acute GVHD and better prophylaxis and treatment of opportunistic infections are required to reduce the incidence of NRM and improve survival. Further studies on pediatric HSCT that include a larger number of patients and more homogenous patient cohorts are desirable. Copyright © 2016 American Society for Blood and Marrow Transplantation.

    Chronic IS is associated with significant morbidity in transplant recipients. Moreover, IS does not prevent chronic graft failure frequently. Allograft immune tolerance in LT can be induced by complete donor chimerism through allogenic HSCT combined with identical LDLT. This approach may exempt patients from chronic lifelong IS. However, it is unclear whether its benefits justify its risks. Here, we present three cases from our institution and analyze seven additional reports of children treated with HSCT/LDLT, all receiving HSCT due to hemato-oncological indications. In eight of 10 cases, donor macrochimerism resulted in allograft tolerance. Nine patients survived. One patient died due to fulminant ADV infection. Further complications were GvHD (n = 3) and bone marrow failure (n = 2). In conclusion, donor-specific allograft tolerance can be achieved by identical-donor HSCT/LDLT. However, at present, this approach should generally be limited to selected indications due to a potentially unfavorable risk-benefit ratio. Novel toxicity-reduced conditioning protocols for HSCT/LDLT in the absence of malignant or non-hepatic disease may prove to be a sufficiently safe approach for inducing graft tolerance in children receiving a LDLT in the future. This concept may reduce the burden of lifelong IS. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2012-02-01

    BACKGROUND: Hurler Syndrome is associated with a deficiency of a specific lysosomal enzyme involved in the degradation of glycosaminoglycans. Hematopoietic stem cell transplantation (HSCT) in early infancy is undertaken to help prevent the accumulation of glycosaminoglycans and improve organ function. AIM: To investigate the oral features and dental health of patients with Hurler Syndrome who have undergone successful HSCT. MATERIALS AND METHODS: Twenty-five patients (median age 8.6 years) post-HSCT (mean age 9.4 months) underwent oral assessment (mean of 7.5 years post-HSCT). RESULTS: Dental development was delayed. Numerous occlusal anomalies were noted including: open-bite, class III skeletal base, dental spacing, primary molar infra-occlusion and ectopic tooth eruption. Dental anomalies included hypodontia, microdontia, enamel defects, thin tapering canine crowns, pointed molar cusps, bulbous molar crowns and molar taurodontism. Tooth roots were usually short\\/blunted\\/spindle-like in permanent molars. The prevalence of dental caries was low in the permanent dentition (mean DMFT 0.7) but high in the primary dentition (mean dmft 2.4). Oral hygiene instruction with plaque and or calculus removal was indicated in 71% of those that were dentate. CONCLUSION: Patients with Hurler Syndrome post-HSCT are likely to have delayed dental development, a malocclusion, and dental anomalies, particularly hypodontia and microdontia.

    A cancer diagnosis and treatment can be a stressful, life-altering experience that can pose a threat to life and raise existential challenges. Spirituality may influence the process of coping with the stress of the cancer experience. Studies of the role of spirituality for Muslim cancer patients and survivors are limited. The aim of this study was to understand the role of spirituality in the cancer experience among Arab Muslim hematopoietic stem cell transplant (HSCT) survivors. In this qualitative, descriptive study, 63 HSCT survivors (mean, 20.2 months) responded to 2 open-ended, self-report questions on the role of spirituality in their HSCT experience. Thematic analysis was used to identify themes related to spirituality. Three dimensions that helped patients cope with their experiences were identified: sickness viewed in light of belief in God, use of religious/spiritual resources, and support from family and community. Two general themes described changes in their faith as a result of having the HSCT procedure: strengthening of faith in God and greater reliance on religious/spiritual activities. Spirituality was important to the Arab Muslim survivors in coping with cancer and HSCT treatment. Muslim cancer survivors are often deeply connected to their religion. Healthcare providers in the United States and other Western countries need to be aware of the unique religious and spiritual needs of Muslim cancer survivors in order to provide them with culturally sensitive care. More research on the spiritual needs of Muslim cancer patients and survivors residing in Western countries is needed.

    Hematopoietic cell transplantation (HCT) is performed in select centers in the United States (U.S.), and patients are often required to temporarily relocate to receive care. The purpose of this study was to identify housing barriers impacting access to HCT and potential solutions. A mixed-methods primary study of HCT social workers was conducted to learn about patient housing challenges and solutions in place that help address those barriers. Three telephone focus groups were conducted with adult and pediatric transplant social workers (n = 15). Focus group results informed the design of a national survey. The online survey was e-mailed to a primary social worker contact at 133 adult and pediatric transplant centers in the U.S. Transplant centers were classified based on the patient population cared for by the social worker. The survey response rate was 49%. Among adult programs (n = 45), 93% of centers had patients that had to relocate closer to the transplant center to proceed with HCT. The most common type of housing option offered was discounted hotel rates. Among pediatric programs (n = 20), 90% of centers had patients that had to relocate closer to the transplant center to proceed with HCT. Ronald McDonald House was the most common option available. This study is the first to explore housing challenges faced by patients undergoing HCT in the U.S. from the perspective of social workers and to highlight solutions that centers use. Transplant centers will benefit from this knowledge by learning about options for addressing housing barriers for their patients.

    The aim of this study was to determine the effectiveness of an implemented exercise program for children throughout the hematopoietic stem cell transplantation (HSCT) process. Twenty-two children aged between 3 and 17, who were earlier selected for HSCT, were divided into two groups-intervention and control. Children's physical function, functional performance, and activities of daily life (ADL) were assessed before HSCT, at discharge, and 1 month later. The exercise program, which consisted of strengthening, endurance, stretching, and relaxation exercises, was implemented to the intervention group for 5 days a week throughout hospitalization; and these exercises were given as home program at discharge. The results of the supervised exercise program during hospitalization showed that the children's physical function and functional performance increased statistically significantly in the intervention group (P exercise program had positive effects throughout the HSCT process, but these effects did not continue during the follow-up period. Exercise programs implemented by physiotherapists are important for children undergoing HSCT, and after transplantation it is necessary to continue supervised exercise program during follow-up. © 2016 Wiley Periodicals, Inc.

    Several prognostic factors for the outcome after allogeneic hematopoietic stem-cell transplant (HSCT) from matched unrelated donors have been postulated from registry data; however, data from randomized trials are lacking. We present analyses on the effects of patient-related, donor-related, and treatment-related prognostic factors on acute GVHD (aGVHD), chronic GVHD (cGVHD), relapse, nonrelapse mortality (NRM), disease-free survival (DFS), and overall survival (OS) in a randomized, multicenter, open-label, phase III trial comparing standard graft-versus-host-disease (GVHD) prophylaxis with and without pretransplantation ATG-Fresenius (ATG-F) in 201 adult patients receiving myeloablative conditioning before HSCT from HLA-A, HLA-B antigen, HLA-DRB1, HLA-DQB1 allele matched unrelated donors. High-resolution testing (allele) of HLA-A, HLA-B, and HLA-C were obtained after study closure, and the impact of an HLA 10/10 4-digit mismatch on outcome and on the treatment effect of ATG-F versus control investigated. Advanced disease was a negative factor for relapse, DFS, and OS. Donor age ≥40 adversely affected the risk of aGVHD III-IV, extensive cGVHD, and OS. Younger donors are to be preferred in unrelated donor transplantation. Advanced disease patients need special precautions to improve outcome. The degree of mismatch had no major influence on the positive effect of ATG-F on the reduction of aGVHD and cGVHD. Copyright © 2012 American Society for Blood and Marrow Transplantation.

  8. Immunizations in solid organ and hematopoeitic stem cell transplant patients: A comprehensive review

    L'Huillier, Arnaud G; Kumar, Deepali

    2015-01-01

    The Solid Organ Transplantation (SOT) and Haematopoietic Stem Cell Transplantation (HSCT) population is continuously increasing as a result of broader indications for transplant and improved survival. Infectious diseases, including vaccine-preventable diseases, are a significant threat for this population, primarily after but also prior to transplantation. As a consequence, clinicians must ensure that patients are optimally immunized before transplantation, to provide the best protection during the early post-transplantation period, when immunosuppression is the strongest and vaccine responses are poor. After 3–6 months, inactivated vaccines immunization can be resumed. By contrast, live-attenuated vaccines are lifelong contraindicated in SOT patients, but can be considered in HSCT patients at least 2 years after transplantation, if there is no immunosuppression or graft-versus-host-disease. However, because of the advantages of live-attenuated over inactivated vaccines - and also sometimes the absence of an inactivated alternative - an increasing number of prospective studies on live vaccine immunization after transplantation are performed and give new insights about safety and immunogenicity in this population.

    Full Text Available Allogeneic hematopoietic stem cell transplantation (HSCT remains a curative option for children with high risk and advanced acute leukemia. Yet availability of matched family donor limits its use and although matched unrelated donor or mismatched umbilical cord blood (UCB are viable options, they fail to meet the global need. Haploidentical family donor is almost universally available and is emerging as the alternate donor of choice in adult patients. However, the same is not true in the case of children. The studies of haploidentical HSCT in children are largely limited to T cell depleted grafts with not so encouraging results in advanced leukemia. At the same time, emerging data from UCBT are challenging the existing paradigm of less stringent HLA match requirements as perceived in the past. The use of posttransplantation cyclophosphamide (PTCY has yielded encouraging results in adults, but data in children is sorely lacking. Our experience of using PTCY based haploidentical HSCT in children shows inadequacy of this approach in younger children compared to excellent outcome in older children. In this context, we discuss the current status of haploidentical HSCT in children with acute leukemia in a global perspective and dwell on its future prospects.

    Full Text Available Background and aims: Clostridium difficile infection (CDI constitutes an important cause of antibiotic-associated diarrhea. Recurrence after first-line treatment with antibiotics is high and fecal microbiota transplantation (FMT may be effective for refractory and recurrent CDI. This series aims to describe the efficacy of FMT in the treatment of refractory and recurrent CDI. Methods: A prospectively recorded single-centre case series of patients with persistent or recurrent CDI treated with FMT between June 2014 and March 2015 was analyzed. Primary and secondary outcomes were defined as resolution of diarrhea without recurrence of CDI within 2 months after one or more FMT, respectively. A descriptive analysis was performed. Results: 8 FMT were performed in 6 patients, 3 with refractory CDI and 3 with recurrent CDI. The median age of recipients was 71 years and 66.7% were women. One FMT was delivered through colonoscopy and the remaining 87.5% through esophagogastroduodenoscopy. One upper FMT was excluded due to recurrence of CDI after antibiotic exposure for a respiratory infection. The overall cure rate of FMT was total with lower route and 83.3% with upper route. Primary cure rate was achieved in 83.3% of patients and secondary cure rate was achieved in all patients. Median time to resolution of diarrhea after FMT was 1 day and no complications were reported during follow-up. Conclusion: FMT appears to constitute a safe and effective approach in the management of refractory and recurrent CDI. Difference between primary and secondary cure rates may result of insufficient restoration of intestinal microbiota with a single FMT.

    Subsequent vitiligo after hematopoietic stem cell transplantation (HSCT) has been described sporadically in case series. To investigate the incidence and risk factors of subsequent vitiligo after HSCT. A nationwide, population-based cohort study was performed using the Korean National Health Insurance Claims Database from 2009 to 2013. All HSCT recipients who had undergone HSCT between 2010 and 2011 and not treatment for vitiligo in 2009 (to exclude preexisting active vitiligo) were included in the HSCT recipient group, and an age- and sex-matched control group without HSCT was also established. A total of 2747 HSCT recipients and 8241 controls were enrolled. Newly acquired vitiligo occurred in 1.06% of HSCT recipients between 2010 and 2013, and there was a significant increase (OR 3.130, 95% CI 1.859-5.271) in cases of vitiligo in HSCT recipients compared with controls (0.34%). Allogeneic HSCT (OR 5.593, 95% CI 1.628-19.213) and bone marrow-sourced stem cells (as compared with peripheral blood-sourced stem cells; OR 2.492, 95% CI 1.114-5.576) were independently associated with the development of vitiligo after HSCT. Medical record review was not available. Vitiligo developed at a significantly increased rate after HSCT compared with controls. Allogeneic HSCT and bone marrow-sourced stem cells were independent risk factors. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

    Liver transplantation is an important treatment option for end-stage liver disease. Since liver transplantation is not performed in Iceland, patients are sent abroad for this procedure. The aim of this study was to investigate indications and results of liver transplantations for Icelandic patients. The study was retrospective and included all patients in Iceland who had undergone liver transplantation from the first transplantation in 1984 to the end of 2012. Information was gathered from medical records. The study period was divided into three subperiods in order to evaluate changes in frequency of transplantation and survival. During the period, 45 liver transplantations, thereof five retransplantations, were performed. Of 40 patients 16 were males, 18 females, mean age 40 years. There were six children, 2 girls and 4 boys with an age range of 0.4-12 years. Number of transplantation per million inhabitants increased significantly (2.40 during 1984-1996; 5.18 during 1997-2006 and 8.90 during 2007-2013; p<0.01). The main indication for transplantation was cirrhosis with complications in 26 patients (65%), acute liver failure in 6 (15%), cirrhosis and hepatocellular carcinoma in three (8%), and hemangioendothelioma in two (5%). The most common underlying liver diseases were primary biliary cirrhosis in 8 (20%), autoimmune hepatitis in four (10%), alcoholic cirrhosis in three (7.5%) and primary sclerosing cholangitis in three (7.5%). The mean waiting time for transplantation was 5.9 months (median 3.2). Survial was 84% in one year and 63% in 5 years. Survival increased during the study period. The number of liver transplantations has increased significantly in recent years. Survival has improved and is comparable to survival in countries where liver transplantations are performed.

    Iron overload is well documented in patients with β-thalassemia major, and patients who have undergone hematopoietic stem cell transplantation (HSCT) remain at risk as a result of pre- and immediate post-HSCT transfusions. This is a prospective, randomized, 1-year clinical trial that compares the efficacy and safety of the once-daily oral iron chelator deferasirox versus phlebotomy for the treatment of iron overload in children with β-thalassemia major following HSCT. Patients (aged 12.4 years) received deferasirox (n = 12, 10 mg/kg/day starting dose) or phlebotomy (n = 14, 6 ml/kg/2 weeks) for 1 year. In two and five patients, deferasirox dose was increased to 15 and 20 mg/kg/day, respectively. Magnetic resonance imaging (MRI)-assessed liver iron concentration (LIC) decreased with deferasirox (mean 12.5 ± 10.1 to 8.5 ± 9.3 mg Fe/g dry weight [dw]; P = 0.0005 vs. baseline) and phlebotomy (10.2 ± 6.8 to 8.3 ± 9.2 mg Fe/g dw; P = 0.05). LIC reductions were greater with deferasirox than with phlebotomy for patients with baseline serum ferritin 1,000 ng/ml or higher (-8.1 ± 1.5 vs. -3.5 ± 5.7 mg Fe/g dw; P = 0.048). Serum ferritin and non-transferrin-bound iron also decreased significantly. In two patients with severe cardiac siderosis, a clinically relevant improvement in myocardial T2* was seen, following phlebotomy and deferasirox therapy (n = 1 each). Adverse effects with deferasirox were skin rash, gastrointestinal upset, and increased liver function tests (all n = 1), while those for phlebotomy were difficulty with venous access (n = 4) and distress during procedure (n = 1). Parents of 13/14 children receiving phlebotomy wished to switch to deferasirox, with 1/14 being satisfied with phlebotomy. Deferasirox treatment or phlebotomy reduces iron burden in pediatric patients with β- thalassemia major post-HSCT, with a manageable safety profile. © 2016 Wiley Periodicals, Inc.

    Holding back, or withholding discussion of disease-related thoughts and emotions, is associated with negative outcomes including lower quality of life, diminished well-being, and relational distress. For patients undergoing hematopoietic stem cell transplantation (HSCT), the degree to which one holds back from discussing illness-related concerns may be an important determinant of social well-being and health; however, this has not been systematically assessed in this population. The purpose of the present study was to assess the moderating effects of holding back discussion of disease-related concerns on the relationship between health-related symptoms and social well-being in adult patients undergoing HSCT. Seventy autologous (n = 55) and allogeneic (n = 15) HSCT patients completed measures of holding back, social well-being, and health symptoms (i.e., pain, fatigue, sleep problems, cognitive problems) both before and after transplantation (i.e., three months after transplantation and six months after transplantation). In patients with average to high levels of holding back, health symptoms were significantly related to lower levels of social well-being; however, for patients with low levels of holding back, the relationship between health symptoms and social well-being was not significant. The results of the present study suggest that the level of holding back may be important in understanding how health-related symptoms relate to social well-being in patients undergoing HSCT. These findings underscore the importance of addressing how patients undergoing HSCT communicate about their disease with others as this may be related to their adjustment to illness and treatment.

    In high-risk acute leukemia patients undergoing haploidentical hematopoietic stem cell transplantation (HSCT), adoptive immunotherapy with T regulatory cells (Tregs) and T conventional cells (Tcons) prevented acute and chronic graft-versus-host disease (GvHD), favored post-transplant immunological reconstitution and was associated with a powerful graft-versus-leukemia (GvL) effect. With a particularly innovative approach, we developed a treatment with a Treg-protected donor lymphocyte infusion (DLI) for patients with early relapse after HSCT and we report here the results obtained in the first patient with APL (M3v) relapsed after a second matched allogeneic HSCT (15% blasts and 75% of donor cells in bone marrow). The patient received a first infusion of 2.5 × 10 6 /kg Tregs derived from matched donor followed 7 days later by 5 × 10 6 /kg Tcons. GvL effect was strongly evident as the percentage of leukemic cells decreased to 5%. A second infusion of Tregs (2.5 × 10 6 /kg) and Tcons (2 × 10 6 /kg) was performed. No GvHD was observed. Disease evaluation showed the absence of blastic cells at flow-cytometry, a normal caryotype and full donor chimerism. We also observed NOTCH1 down-regulation in peripheral blood. This new immunotherapy approach showed that Treg-protected DLI is effective in preventing GvHD and is associated with a strong GvL effect.

    2015-01-01

    Full Text Available Background: The ABO blood group system is of prime significance in red cell transfusion and organ transplantation. However, ABO compatibility is not critical in allogenic hemopoietic stem cell transplantation (HSCT and approximately 40-50% of hemopoietic stem cell transplants are ABO incompatible. This incompatibility may be major, minor or bi-directional. Though there are descriptions of transfusion practice and protocols in ABO incompatible HSCT, there are considerable variations and transfusion support in these patients can be very challenging. Aims: The immunohematologic observations in two cases of bi-directional ABO incompatible HSCT have been described, and clinico-serologic correlation has been attempted. Materials and Methods: In both cases, peripheral blood stem cell harvests were obtained using the Cobe spectra cell separator. Immunohematologic assessments in the donor and recipient were done as a part of pre HSCT evaluation. Both the standard tube technique and column agglutination method (Ortho Biovue Micro Bead System was used. Antibody screen was done by column agglutination method using three cell panel (Surgiscreen cells. Isoagglutinin titration was done by the master dilution method and standard validated techniques were used. Results: The pattern of laboratory findings in the two cases was different and so were the clinical outcomes. Although there was early engraftment in the first case, the second case developed pure red cell aplasia and this was well-reflected in the immunohematologic assessments. Conclusion: Immunohematologic assessment correlated well with the clinical picture and could be used to predict clinical outcome and onset of complications in ABO incompatible HSCT.

    2015-01-01

    The reported incidence of post allogeneic hematopoietic stem cell transplant (HSCT) auto-immune hemolytic anemia (AIHA) was between 4.4% and 6% following a single transplant. Cord blood transplantation, T-cell depletion and chronic GvHD are significantly associated with post-transplant AIHA. During an 11 year period, data for 500 pediatric HSCT recipients were eligible for evaluation of the incidence of AIHA post first and second transplants. Demographic, transplant, and post-transplant related variables were analyzed. Twelve/500 (2.4%) recipients at a median of 273 days and 7/72 (9.7%) recipients at a median of 157 days developed AIHA post first and second HSCT respectively. Post first HSCT, none of the matched related donor recipients developed AIHA (0/175 MRD vs. 12/325 other donors, p=0.04). Four/12 required a second HSCT to control the AIHA. Post the second HSCT, matched unrelated donor was significantly associated with the development of AIHA. No other variables were associated with the post-second transplant AIHA. The incidence of AIHA post first and second HSCT was less than reported. The increased incidence of AIHA among recipients of second HSCT is most likely due to the profound immune dysregulation. A much larger, prospective study would be needed to evaluate the incidence, complications and management of post-transplant AIHA. PMID:25809012

    Human herpesvirus-6 (HHV-6) is known to reactivate after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and may be associated with development of acute graft-versus-host disease (GVHD) and nonrelapse mortality (NRM). However, the clinical significance of HHV-6 reactivation after allo-HSCT remains unclear. Therefore, we conducted a retrospective analysis to elucidate the impact of HHV-6 reactivation on transplantation outcomes. Of 236 patients who underwent allo-HSCT, 138 (58.5%) developed HHV-6 reactivation and 98 (41.5%) did not. Univariate analysis indicated that at 3 years, patients with HHV-6 reactivation had significantly higher NRM (27.7% versus 13.7%, P = .003) and worse overall survival (42.1% versus 59.0%, P = .008) than those without reactivation. In multivariate analysis, HHV-6 reactivation was associated with higher incidence of acute GVHD (hazard ratio [HR], 1.87; P = .01), cytomegalovirus reactivation (HR, 2.24; P impact of HHV-6 reactivation on acute GVHD was observed only in patients who received myeloablative conditioning (MAC). These results indicate that HHV-6 reactivation was associated with development of acute GVHD, cytomegalovirus reactivation, and NRM. Furthermore, adverse impact of HHV-6 reactivation on transplantation outcomes was prominent in the setting of MAC. Copyright © 2015 American Society for Blood and Marrow Transplantation.

    There are few reports about laparoscopic approach after liver transplantation (LT). The aim of this paper is to analyze in terms of feasibility and therapeutic effectiveness an initial experience with laparoscopy in patients who have had a liver transplantation. Laparoscopic procedures were divided into "early" and "late" laparoscopy. A total of 10 laparoscopic procedures after LT were performed in 9 patients: 3 early and 7 late. The early laparoscopic procedures were performed in 3 patients who had a torpid evolution in their liver transplant: 2 were diagnostic only and 1 was also therapeutic. There were no intraoperative events or conversions. We recorded 2 complications. In 7 patients a late laparoscopy was performed: 4 in the upper abdomen and 3 in the lower abdomen. Of the 4 in the upper abdomen, 3 were liver procedures and 1 was in the transverse colon, on the other side; in addition, 2 laparoscopic inguinal hernia repairs and 1 laparoscopic appendectomy also were performed. None of these 7 cases was converted, and there were no intraoperative events. The early postoperative period, in critically ill patients diagnostic and eventually therapeutic laparoscopy was feasible and effective in our cases. Late laparoscopy in the upper abdomen is difficult due to adhesions and adds to the risk of poor graft function, but was feasible for both diagnostic and therapeutic purposes. Late laparoscopy in the lower abdomen with good graft function has the same safety and efficacy as those performed on nontransplanted patients. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Liver grafts from donation after circulatory death (DCD donors are increasingly accepted as an extension of the organ pool for transplantation. There is little data on the outcome of liver transplantation with DCD grafts from a pediatric donor. The objective of this study was to assess the outcome of liver transplantation with pediatric DCD grafts and to compare this with the outcome after transplantation of livers from pediatric donation after brain death (DBD donors.All transplantations performed with a liver from a pediatric donor (≤16 years in the Netherlands between 2002 and 2015 were included. Patient survival, graft survival, and complication rates were compared between DCD and DBD liver transplantation.In total, 74 liver transplantations with pediatric grafts were performed; twenty (27% DCD and 54 (73% DBD. The median donor warm ischemia time (DWIT was 24 min (range 15-43 min. Patient survival rate at 10 years was 78% for recipients of DCD grafts and 89% for DBD grafts (p = 0.32. Graft survival rate at 10 years was 65% in recipients of DCD versus 76% in DBD grafts (p = 0.20. If donor livers in this study would have been rejected for transplantation when the DWIT ≥30 min (n = 4, the 10-year graft survival rate would have been 81% after DCD transplantation. The rate of non-anastomotic biliary strictures was 5% in DCD and 4% in DBD grafts (p = 1.00. Other complication rates were also similar between both groups.Transplantation of livers from pediatric DCD donors results in good long-term outcome especially when the DWIT is kept ≤30 min. Patient and graft survival rates are not significantly different between recipients of a pediatric DCD or DBD liver. Moreover, the incidence of non-anastomotic biliary strictures after transplantation of pediatric DCD livers is remarkably low.

    In the absence of cadaveric grafts, a living donor liver transplant program was started in Algeria in February 2003. The aim of this study is to report the preliminary results. From February 2003 to September 2004, eight adult-to-adult living related liver transplantations were performed. The donors were six women and two men of mean age of 25 years (range, 18 to 48 years). Right hepatectomy was performed in seven patients and left hepatectomy in one patient. The recipients were four women and four men of mean age 33 years (range, 16 to 56 years). Follow-up ranged from 1 month to 18 months (median 7 months). All donors survived the procedure. In the immediate postoperative period, two donors experienced complications. One donor underwent reoperation for hemorrhage and one suffered partial portal vein thrombosis, which was treated medically. The eight donors are alive at home without any late complications. One recipient died on postoperative day 43 due to sepsis. Among the seven other recipients, two experienced complications: one bilioma in relation to a biliary-intestinal fistula and one thrombosis of the splenic vein with a left portal embolus. At present the seven recipients are alive with normal liver function and without complications. Our results are comparable to other reports suggesting that adult-to-adult living related liver transplantation is feasible with no mortality and low morbidity in donors. However, it is important to develop a cadaveric liver transplant program.

    Full Text Available Objective: The main aim of this study was to determine the correlation between clinical outcome and heme oxygenase-1 (HO-1 expression before and after hematopoietic stem cell transplantation (HSCT in acute leukemia. Methods: HO-1 mRNA levels in 83 patients were measured using qRT-PCR. In a comparative analysis of HO-1 levels in relation to different post-transplant outcomes, the HO-1 threshold, determined via the receiver operating characteristic (ROC curve, was effectively used to predict clinical relapse and acute graft-versus-host disease (aGVHD. The correlations among clinical relapse, aGVHD and HO-1 expression were analyzed based on this threshold. Results: Leukemia risk stratification and relative expression of HO-1 before pretreatment had significant effects on clinical relapse. Leukemia risk stratification, relative expression of HO-1 after HSCT and the interval from diagnosis to transplantation had a significant influence on aGVHD. Both relapse and aGVHD appeared to be associated with relative HO-1 expression. The relative expression rate of HO-1 was 1.131-1.186 before pretreatment, and strongly associated with post-transplantation relapse. The relative expression rate of HO-1 was 1.102-1.144 after transplantation, and closely related to aGVHD. ROC curve analysis revealed high specificity and sensitivity of HO-1 expression in predicting relapse and aGVHD after allo-HSCT. Conclusions: HO-1 expression can be effectively used as a predictor of relapse as well as a diagnostic factor of aGVHD after transplantation for allo-HSCT patients with acute leukemia.

Before transplantation, patients receive intensive myeloablative chemoradiotherapy followed by stem cell “rescue.” Autologous HSCT is performed using the patient’s own hematopoietic stem cells, which are harvested before transplantation and reinfused after myeloablation. Allogeneic HSCT uses human leukocyte antigen (HLA-matched stem cells derived from a donor. Survival after allogeneic transplantation depends on donor–recipient matching, the graft-versus-host response, and the development of a graft versus leukemia effect. This article reviews the biology of stem cells, clinical efficacy of HSCT, transplantation procedures, and potential complications.Keywords: hematopoietic stem cell transplantation, complications

    Elevated serum ferritin contributes to treatment-related morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). The multicenter DE02 trial assessed the safety, efficacy and impact of deferasirox on iron homeostasis after allogeneic HSCT. Deferasirox was administered at a starting dose of 10 mg/kg per day to 76 recipients of allogeneic HSCT, with subsequent dose adjustments based on efficacy and safety. Deferasirox was initiated at a median of 168 days after HSCT, with 84% of patients still on immunosuppression. Baseline serum ferritin declined from 2045 to 957 ng/mL. Deferasirox induced a negative iron balance in 84% of patients. Hemoglobin increased in the first 3 months, and trough serum cyclosporine levels were stable. Median exposure was 330 days, with a median compliance rate of >80%. The most common investigator-reported drug-related adverse events (AEs) were increased blood creatinine (26.5%), nausea (9.0%) and abdominal discomfort (8.3%). Fifty-four (71.1%) patients experienced drug-related AEs, which occasionally resulted in discontinuation (gastrointestinal (n=6), skin (n=3), elevated transaminases (n=1) and creatinine (n=1)). The incidence of AEs appeared to be dose related, with 7.5 mg/kg per day being the best-tolerated dose. Low-dose deferasirox is an effective chelation therapy after allogeneic HSCT, with a manageable safety profile, even in patients receiving cyclosporine.

    Full Text Available In the last decades, the global epidemiological impact of invasive candidiasis (IC in patients with hematologic malignancies (HM and in hematopoietic stem cell transplant (HSCT recipients has decreased and the incidence of invasive aspergillosis  exceeded that of Candida infections. The use of prevention strategies, first of all antifungal prophylaxis with triazoles,  contributed to the reduction of IC in these populations as demonstrated by several  epidemiological studies. However, relatively little is known about the current epidemiological patterns of IC in HM and HSCT populations, because recent epidemiological data almost exclusively derive from retrospective experiences and few prospective data are available. Several prospective, controlled studies in the prophylaxis of invasive fungal diseases have been conducted in both the HM and HSCT setting. On the contrary, most of the prospective controlled trials that demonstrated the efficacy of the antifungal drugs echinocandins and voriconazole in the treatment of candidemia and invasive candidiasis mainly involved  patients with underlying conditions other than HM or  HSCT.  For these reasons, international guidelines provided specific indications for the prophylaxis strategies in HM and HSCT patients, whereas the  recommendations on therapy of documented Candida infections are based on the results observed in the general population and should be considered with caution.

Liver transplantation has emerged as a good option for early-stage hepatocellular carcinoma yielding survival rates as good as for recipients without this type of tumor. Objective - To assess the outcome of cirrhotic patients with hepatocellular carcinoma undergoing liver transplantation at the Liver Transplantation Service of the "Hospital de Clínicas", Federal University of Paraná, Curitiba, PR, Brazil. Methods - Retrospective study of cirrhotic patients with hepatocellular carcinoma undergoing orthotopic liver transplantation at the mentioned Institution between September 1991 and September 2000. The diagnosis of hepatocellular carcinoma was established during the pretransplant workup in five patients and the tumor was an incidental finding in the native liver in three. The indication for liver transplantation was restricted to solitary tumor equal to or less than 5 cm or up to 3 nodules, with each nodule measuring less than 3 cm, and no evidence of vascular invasion or extrahepatic spread. Patient survival and evidence of tumoral recurrence posttransplant were evaluated. Results - The most common cause for pretransplantation liver disease was hepatitis C virus (50%. On examination of the explanted liver, the majority of patients (6/8, 75% had a single lesion; one patient had two nodules and one had a multifocal hepatocellular carcinoma found incidentally in the native liver. Tumor size ranged from 0,2 to 5,0 cm. All cases had neither vascular invasion nor linfonodal envolvement. All patients remained alive and free of tumor recurrence at the time of the study with a mean follow-up of 18,5 months (range, 5-29 months. Conclusion - Liver transplantation is a good therapeutic option for early stage hepatocellular carcinoma arising in

    Full Text Available Objective: To determine the sensitivity and significance of B-cell chimerism for the detection of early engraftment, transplant rejection, and disease relapse. Methods: The dynamic monitoring of lineage-specific cell subtypes (B, T, and NK cells was made in 20 B-cell acute lymphoblastic leukemia (B-ALL patients following allogeneic hematopoietic stem cell transplantation (allo-HSCT. In the early period after allo-HSCT, the latest establishment of B-cell complete chimerism (CC was observed in a majority of patients. Results: The percentage of donor cells of B-cell lineage was lower than the percent of T-cell lineage in most of the mixed chimerism (MC patients. During graft rejection, the frequency of patients with decreasing MC of B-, T- and NK-cell lineage were 5/5, 2/5, and 2/5. When disease relapsed, five patients showed a faster decrease of the donor percent of B-cells than of T- or NK-cells. Only one patient displayed a more rapid decrease in NK-cells than in T- or B-cells. Conclusion: Monitoring of B-cell chimerism after HSCT seems to be valuable for insuring complete engraftment, anticipating graft rejection, and relapse in B-ALL patients.

    Influenza virus infection can cause fatal complications (e.g., pneumonia) in immunodeficient long-term survivors of allogeneic hematopoietic stem cell transplantation (allo-HSCT). The immune response to the vaccine improves if it is administered at >1 year after allo-HSCT, although the response may vary according to the patient's immune status. We sought to identify predictors of immune response to trivalent inactivated influenza vaccine (TIV) among patients vaccinated at >1 year after allo-HSCT. We included 27 allo-HSCT recipients, with a median interval of 4.3 years (range 1.0-10.1 years) from transplantation to vaccination. Nineteen patients achieved a response to TIV, although a low immune response to TIV was significantly associated with calcineurin inhibitor treatment, and moderate chronic graft-versus-host disease and IgM levels of immune response to TIV. These results indicate that a more effective approach is needed to induce a vaccine-specific immune response among long-term survivors of allo-HSCT who have low serum IgM levels.

    In subjects mismatched in the HLA alleles C*03:03/C*03:04 no allogeneic cytotoxic T-lymphocyte responses are detected in vitro. Hematopoietic stem cell transplantation (HSCT) with unrelated donors (UDs) showed no association between the HLA-C allele mismatches (CAMMs) and adverse outcomes; antigen mismatches at this and mismatches other HLA loci are deleterious. The absence of effect of the CAMM may have resulted from the predominance of the mismatch C*03:03/C*03:04. Patients with hematologic malignancies receiving UD HSCT matched in 8/8 and 7/8 HLA alleles were examined. Transplants mismatched in HLA-C antigens or mismatched in HLA-A, -B, or -DRB1 presented significant differences (P HLA mismatches. PMID:24408320

    2018-02-01

    Full Text Available Human adenoviruses (HAdV are a major cause of morbidity and mortality in pediatric human stem cell transplant (HSCT recipients. Our previous studies identified the gastrointestinal tract as a site of HAdV persistence, but the role of intestinal virus shedding pre-transplant for the risk of ensuing invasive infection has not been entirely elucidated. Molecular HAdV monitoring of serial stool samples using RQ-PCR was performed in 304 children undergoing allogeneic HSCT. Analysis of stool and peripheral blood specimens was performed pre-transplant and at short intervals until day 100 post-HSCT. The virus was detected in the stool of 129 patients (42%, and 42 tested positive already before HSCT. The patients displaying HAdV shedding pre-transplant showed a significantly earlier increase of intestinal HAdV levels above the critical threshold associated with high risk of invasive infection (p < 0.01. In this subset of patients, the occurrence of invasive infection characterized by viremia was significantly higher than in patients without HAdV shedding before HSCT (33% vs 7%; p < 0.0001. The data demonstrate that intestinal HAdV shedding before HSCT confers a greatly increased risk for invasive infection and disseminated disease post-transplant, and highlights the need for timely HAdV monitoring and pre-emptive therapeutic considerations in HSCT recipients.

    Stem cell transplant has been the focus of clinical research for a long time given its potential to treat several incurable diseases like hematological malignancies, diabetes mellitus, and neuro-degenerative disorders like Parkinson disease. Hematopoietic stem cell transplantation (HSCT) is the oldest and most widely used technique of stem cell transplant. HSCT has not only been used to treat hematological disorders including hematological malignancies, but has also been found useful in treamtent of genetic, immunological, and solid tumors like neuroblastoma, lymphoma, and germ cell tumors. In spite of the rapid advances in stem cell technology, success rate with this technique has not been universal and many complications have also been seen with this form of therapy. The key to a successful HSCT therapy lies in early diagnosis and effective management of complications associated with this treatment.

    Survivors of hematopoietic stem cell transplant (HSCT) have experienced a life threatening and potentially traumatic illness and treatment that make them vulnerable to long lasting negative psychological outcomes, including anxiety and depression. Nevertheless, studies show that overcoming cancer and its treatment can present an opportunity for personal growth and psychological health (reduced symptoms of anxiety and depression and high levels of emotional well-being) through resilience. However, research has not yet clarified what differentiates HSCT survivors who experience psychological growth from those who do not. By analyzing recovery narratives, we examined whether HSCT survivors' interpretation of their experiences helps explain differences in their post-treatment psychological health. Guided by narrative psychology theory, we analyzed the narratives of 23 HSCT survivors writing about their experience of cancer treatment. Psychological health was measured by: (1) emotional well-being subscale part of the Functional Assessment of Cancer Therapy Bone Marrow Transplant (FACT-BMT), (2) depression, and (3) anxiety subscales of the Brief Symptom Inventory. Findings revealed a positive relation between psychological health and a greater number of redemption episodes (going from an emotionally negative life event to an emotionally positive one) as well as fewer negative emotional expressions. SIGNIFICANCE OF THE RESULTS: Theoretical and practical implications of these findings are discussed, showing how narratives can inform interventions to assist cancer survivors with their psychological recovery.

    Full Text Available Abstract Background Primary refractory acute myeloid leukemia (PRF-AML is associated with a dismal prognosis. Allogeneic stem cell transplantation (HSCT in active disease is an alternative therapeutic strategy. The increased availability of unrelated donors together with the significant reduction in transplant-related mortality in recent years have opened the possibility for transplantation to a larger number of patients with PRF-AML. Moreover, transplant from unrelated donors may be associated with stronger graft-mediated anti-leukemic effect in comparison to transplantations from HLA-matched sibling donor, which may be of importance in the setting of PRF-AML. Methods The current study aimed to address the issue of HSCT for PRF-AML and to compare the outcomes of HSCT from matched sibling donors (n = 660 versus unrelated donors (n = 381, for patients with PRF-AML between 2000 and 2013. The Kaplan-Meier estimator, the cumulative incidence function, and Cox proportional hazards regression models were used where appropriate. Results HSCT provide patients with PRF-AML a 2-year leukemia-free survival and overall survival of about 25 and 30%, respectively. In multivariate analysis, two predictive factors, cytogenetics and time from diagnosis to transplant, were associated with lower leukemia-free survival, whereas Karnofsky performance status at transplant ≥90% was associated with better leukemia-free survival (LFS. Concerning relapse incidence, cytogenetics and time from diagnosis to transplant were associated with increased relapse. Reduced intensity conditioning regimen was the only factor associated with lower non-relapse mortality. Conclusions HSCT was able to rescue about one quarter of the patients with PRF-AML. The donor type did not have any impact on PRF patients’ outcomes. In contrast, time to transplant was a major prognostic factor for LFS. For patients with PRF-AML who do not have a matched sibling donor, HSCT from an

    Apart from solid organ transplantations, use of ABO-blood group mismatched (ABO-mismatched) donors is acceptable in hematopoietic stem cell transplantation (HSCT) patients. About 20-40% of allogeneic HSCT recipients will receive grafts from ABO-mismatched donors. ABO incompatible HSCT procedures are associated with immediate and late consequences, including but not restricted to acute or delayed hemolytic reactions, delayed red blood cell recovery, pure red cell aplasia and graft-versus-host disease. This review summarizes the current knowledge about consequences of ABO-mismatched HSCT in terms of associated complications and will evaluate its impact on important outcome parameters of HSCT.

    Results of reduced intensity conditioning regimen (RIC) in the HLA identical haematopoietic stem cell transplantation (HSCT) setting have not been compared to those after myeloablative (MA) regimen HSCT in patients with acute myeloblastic leukaemia (AML) over 50 years of age. With this aim, outcomes of 315 RIC were compared with 407 MA HSCT recipients. The majority of RIC was fludarabine-based regimen associated to busulphan (BU) (53%) or low-dose total body irradiation (24%). Multivariate analyses of outcomes were used adjusting for differences between both groups. The median follow-up was 13 months. Cytogenetics, FAB classification, WBC count at diagnosis and status of the disease at transplant were not statistically different between the two groups. However, RIC patients were older, transplanted more recently, and more frequently with peripheral blood allogeneic stem cells as compared to MA recipients. In multivariate analysis, acute GVHD (II-IV) and transplant-related mortality were significantly decreased (P=0.01 and P<10(-4), respectively) and relapse incidence was significantly higher (P=0.003) after RIC transplantation. Leukaemia-free survival was not statistically different between the two groups. These results may set the grounds for prospective trials comparing RIC with other strategies of treatment in elderly AML.

    Acute B lymphoblastic leukemia (B-ALL) relapse contributes predominantly to the mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, the mechanism of B-ALL relapse after allo-HSCT remains unknown. The eradication of leukemia after allo-HSCT largely relies on graft-versus-leukemia (GVL) effects mediated by donor T cells. T cell exhaustion, characterized by the increased expression of inhibitory receptors and impaired function, may suppress GVL effects. In this study, we evaluated whether T cell exhaustion was involved in B-ALL relapse after allo-HSCT. The results showed that CD4 + and CD8 + T cells exhibited increased coexpression of PD-1 and Tim-3, and compromised proliferative capacity, cytokine production and cytotoxic potentials in relapsed patients. Additionally, T cells at the tumor site were more easily exhausted than T cells in the peripheral blood. Moreover, the reversal of T cell exhaustion might correlate with effective anti-leukemic responses after reinduction. These results suggested that T cell exhaustion was associated with B-ALL relapse after allo-HSCT as well as its treatment outcome. Copyright © 2017. Published by Elsevier Inc.

    Interest groups advocate centre-specific outcome data as a useful tool for patients in choosing a hospital for their treatment and for decision-making by politicians and the insurance industry. Haematopoietic stem cell transplantation (HSCT) requires significant infrastructure and represents a cost-intensive procedure. It therefore qualifies as a prime target for such a policy. We made use of the comprehensive database of the Swiss Blood Stem Cells Transplant Group (SBST) to evaluate potential use of mortality rates. Nine institutions reported a total of 4717 HSCT - 1427 allogeneic (30.3%), 3290 autologous (69.7%) - in 3808 patients between the years 1997 and 2008. Data were analysed for survival- and transplantation-related mortality (TRM) at day 100 and at 5 years. The data showed marked and significant differences between centres in unadjusted analyses. These differences were absent or marginal when the results were adjusted for disease, year of transplant and the EBMT risk score (a score incorporating patient age, disease stage, time interval between diagnosis and transplantation, and, for allogeneic transplants, donor type and donor-recipient gender combination) in a multivariable analysis. These data indicate comparable quality among centres in Switzerland. They show that comparison of crude centre-specific outcome data without adjustment for the patient mix may be misleading. Mandatory data collection and systematic review of all cases within a comprehensive quality management system might, in contrast, serve as a model to ascertain the quality of other cost-intensive therapies in Switzerland.

    Pancreatic cancer is the third most common cancer related cause of death. Even in the 15% of patients who are eligible for surgical resection the outlook is dismal with less than 10% of patients surviving after 5 years. Allogeneic hematopoietic (allo-HSCT) stem cell transplantation is an established treatment capable of to providing cure in a variety of hematopoietic malignancies. Best results are achieved when the underlying neoplasm has been turned into a stage of minimal disease by chemotherapy. Allo-HSCT in advanced solid tumors including pancreatic cancer have been of limited success, however studies of allo-HSCT in solid tumors in minimal disease situations have never been performed. The aim of this trial is to provide evidence for the clinical value of allo-HSCT in pancreatic cancer put into a minimal disease status by effective surgical resection and standard adjuvant chemotherapy. The STEM PACE trial is a single center, phase II study to evaluate adjuvant allogeneic hematopoietic stem cell transplantation in pancreatic cancer after surgical resection. The study will evaluate as primary endpoint 2 year progression free survival and will generate first time state-of-the-art scientific clinical evidence if allo-HSCT is feasible and if it can provide long term disease control in patients with effectively resected pancreatic cancer. Screened eligible patients after surgical resection and standard adjuvant chemotherapy with HLA matched related stem cell donor can participate. Patients without a matched donor will be used as a historical control. Study patients will undergo standard conditioning for allo-HSCT followed by transplantation of allogeneic unmanipulated peripheral blood stem cells. The follow up of the patients will continue for 2 years. Secondary endpoints will be evaluated on 7 postintervention visits. The principal question addressed in this trial is whether allo-HSCT can change the unfavourable natural course of this disease. The underlying

    Karyotype analysis in acute myeloid leukemia (AML) is one of the powerful prognostic factors for complete remission (CR), relapse, and overall survival (OS). Cytogenetic mosaicism is considered to be one of the important characteristics in expression of phenotypic manifestations. However, it has not come into focus due to emerging molecular biological approaches and the results of a number of mutation studies. Clinical correlates and prognostic relevance of mosaicism were evaluated in 163 AML patients [adverse-risk karyotypes (n = 72) and undefined karyotypes (n = 91)]. All patients were treated by induction and consolidation chemotherapies and finally went on hematopoietic stem cell transplantations (HSCT). Patients were divided into two subgroups, either with or without normal karyotype (NK) mosaicism. Seventy patients exhibited NK mosaicism and 93 did not. There were no significant differences in age, gender, chemotherapy cycles to achieve CR, HSCT donor type, source or intensity properties between the two subgroups. We found that NK mosaicism remaining in adverse-risk and undefined karyotype at diagnosis significantly correlates with better OS (p = 0.001) and lower CIR (p = 0.021) rate after HSCT. Our data show that the poor prognostic properties of unfavorable risk karyotype can be overcome to a great extent by allogeneic HSCT and chronic GVHD, especially in the subgroup with NK mosaicism. Cytogenetic mosaicism at initial diagnosis can be an influential factor for survival outcomes, even after HSCT.

    In the last years we have seen an ever increasing number of patients with haematologic disorders who need hematopoietic stem cell transplantation (HSCT). The whole sector of HSCT results, infact to be in a continous scientific and technological clinical progress, offering a very advanced care. Despite this, some aspects are underconsidered, some of which could be fundamental to determine the success of the care pathway, such as the experience of the illness by the patient. Using a Narrative Based Medicine approach we wanted to investigate clinical, psychosocial and organizational aspects of the patient's journey whilst undergoing HSCT. Various narrative interviews were conducted using non-structured approach. Results were analysed by thematic contents. Psycological dimension is the most compromised: above all emerged sentiments of oppression linked to the isolation period in the Low Bacterial Load (LBL) room. To note are also the different dynamics with which the patients perceive the organisation and hospital structures, and how much these factors can influence their care experience. Results suggest the need in clinical practice of an integration between qualitative and clinical approach, so as to permit the psychosocial and relational necessities to emerge, often unexpressed by patients undergoing HSCT.

    Most of the difficulties when trying to realize the proposal to prescribe physical activity for transplantation patients come from patient attitudes and cultural beliefs that ignore the benefits of exercise, but there also are organizational aspects arising from the difficulties that these patients face in accessing supervised exercise facilities. To address these difficulties, the Italian study project "Transplant … and Now Sport" was developed based on a model of cooperation among transplantation specialists, sports physicians, and exercise specialists organized as a team combining their specific skills to effectively actuate the physical exercise programs. This preliminary report is based on 26 patients (16 male, 10 female; 47.8±10.0 years old; 21 kidney and 5 liver transplantations; time from transplantation 2.3±1.4 years) who performed prescribed and supervised exercises consisting of 3 sessions per week of aerobic and strengthening exercises for 1 year. Preliminary results show a significant decrease in body mass index (t=1.966; PSocial Functioning, and Role Emotional scale scores showed a significant improvement (PSport" show the positive effects of the model based on cooperation among transplantation centers, sports medicine centers, and gyms in the administration of a supervised exercise prescription. These data should be considered a contribution to developing and promoting further detailed exercise protocols and to fostering improved posttransplantation health and survival, helping to ensure that physical activity becomes a safe routine medical treatment plan of patient management.

    Allogeneic hematopoietic stem cell transplant (HSCT) recipients are at substantial risk for a variety of infections depending upon numerous factors, such as degree of immunosuppression, host factors, and period after transplantation. Bacterial, fungal, viral, as well as parasitic infections can occur with high morbidity and mortality. The aim of this study was to evaluate the magnitude of the occurrence of parasitic infections in allogeneic HSCT recipients. Modalities of transmission, methods of diagnosis, treatment, donor and recipient pre-transplant screening and prevention measures of the most serious parasitic infections have also been discussed. We systematically reviewed literature records on post-transplant (allogeneic HSCT) parasitic infections, identified through PubMed database searching, using no language or time restrictions. Search was concluded on December 31, 2015. In the present review, we only discussed post-transplant parasitic infections in allogeneic HSCT. Only exclusion criteria were absence of sufficient information on the transmission of parasitic infection to the recipient. Autologous HSCT recipients have not been included because of the absence of a proper allogeneic transplantation even in presence of blood or blood product transfusions. The methods and findings of the present review have been reported based on the preferred reporting items for systematic reviews and meta-analysis checklist (PRISMA). Regarding allogeneic HSCT recipients, from data published in the literature the real burden of parasitic infections cannot be really estimated. Nevertheless, a positive trend on publication number exists, probably because of more than one reason: (i) the increasing number of patients transplanted and then treated with immunosuppressive agents, (ii) the "population shift" resulting from immigration and travels to endemic areas, and (iii) the increasing of attention for diagnosis/notification/publication of cases.

    Full Text Available Allogeneic hematopoietic stem cell transplantation (allo-HSCT is a most powerful immunotherapy for hematological malignancies. However, the impact of immunological disturbances as a result of allo-HSCT is not understood well. We experienced an 11-year-old boy who presented with systemic lupus erythemathosus (SLE 10 years after unrelated cord blood transplantation of male origin for juvenile myelomonocytic leukemia (JMML with monosomy 7. Bone marrow examination showed complete remission without monosomy 7. Genetic analysis of peripheral blood revealed mixed chimera with recipient cells consisting of <5% of T cells, 50–60% of B cells, 60–75% of NK cells, 70–80% of macrophages, and 50–60% of granulocytes. Significance of persistent mixed chimera as a cause of SLE is discussed.

    Full Text Available Abstract Background Prevalence of vancomycin-resistant enterococci has increased in Germany. Here, we report the cluster of linezolid- and vancomycin-resistant Enterococcus faecium (LVRE in a German department for hematologic stem cell transplantation (HSCT. Methods In this retrospective analysis we included all patients with LVRE in a university-based department for HSCT in 2014 and 2015. Patients chart reviews were used to investigate the epidemiology and clinical outcome. Available LVRE isolates underwent detailed microbiological characterization and genotyping by pulsed-field gel electrophoresis (PFGE. Results In total, 20 patients with LVRE were identified within the observed time period. All except two patients underwent allogeneic HSCT. Surveillance culture results from incoming patients and chart review revealed that 10 of 20 patients were colonized at hospital admission. Eight of 10 patients with in-hospital acquired LVRE had previous linezolid treatment. Analysis of spatio-temporal patterns showed no evidence for LVRE patient-to-patient or environment-to-patient transmission within the HSCT department. In five cases (25 % LVRE bloodstream infection occurred. Nine LVRE isolates could be saved for characterization. Eight isolates carried vanA, one isolate vanB. PFGE analysis showed that four different LVRE clones were responsible for the cluster. One single genotype was present in six LVRE isolates whereupon the corresponding patients were all referred from the same hospital to the HSCT department. Conclusions This is the first report demonstrating the emergence of LVRE in a German HSCT department. (LVRE screening at patients’ admission and appropriate infection control strategies were sufficient to prevent any transmission. Further studies in this predisposed patient collective are warranted.

    The treatment-related burden for patients undergoing hematopoietic stem cell transplantation (HSCT) may be relieved by physical exercises. The purpose of this study was to summarize and analyze the evidence provided by randomized controlled trials (RCTs) on physical exercise interventions among patients with cancer undergoing HSCT. PubMed, CINAHL, EMBASE, the Cochrane Library, and PEDro were searched for relevant RCTs up to October 1, 2011. Two reviewers screened articles on inclusion criteria and indentified relevant RCTs. Two authors assessed the selected articles for risk of bias. Data extraction was performed by 1 reviewer. Meta-analyses were undertaken to estimate the outcomes quality of life (QOL), psychological well-being and distress, and fatigue. Eleven studies were included, with study populations consisting of recipients undergoing either an allogeneic or autologous HSCT (n=734). Four studies had low risk of bias. The exercise interventions were performed before, during, and after hospitalization for the HSCT. Different exercise programs on endurance, resistance and/or activities of daily living training, progressive relaxation, and stretching were used. Meta-analyses showed that exercise during hospitalization led to a higher QOL (weighted mean difference=8.72, 95% confidence interval=3.13, 14.31) and less fatigue (standardized mean difference=0.53, 95% confidence interval=0.16, 0.91) in patients with an allogeneic HSCT at the moment of discharge from the hospital. No marked effects were found for psychological well-being and distress. Individual study results suggested significant positive effects on QOL, fatigue, psychological well-being and distress, and physical functioning. Prevalent shortcomings in the included studies were the heterogeneity among studies and the lack of blinding of participants, personnel, and outcome assessment. The results suggest that recipients of HSCT may benefit from physical exercise.

    Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has become one of the standard treatment for hematological diseases. Although the clinical outcome has improved significantly during the last decades, the morbidity and mortality after allo-HSCT are still obstacles to cure. Out of major morbidities, opportunistic virus infections such as cytomegalovirus (CMV) infection are important complications, in particular in patients who received human leukocyte antigen-mismatched HSCT. Here, we aim to summarize information about current and future therapeutic options in CMV disease after allo-HSCT. Recently, not only new drugs but also adoptive T-cell therapy are tested in the setting of clinical trials. CMV prophylaxis using letermovir significantly reduced the incidence of CMV disease in comparison to placebo in a phase III clinical trial. Meanwhile, adoptive T-cell therapies which are fully adapted to good manufacturing practice (GMP) conditions are now available. A recent multicenter study in Germany showed a promising result using Streptamer-isolated T-cell therapy. With the recent development of CMV-targeted therapy, treatment strategies of CMV infection would be further sophisticated in the near future. VIDEO ABSTRACT: http://links.lww.com/COID/A19.

    Full Text Available &lt;b&gt;Purpose:&lt;/b&gt; Lymphocyte subset recovery is an important factor that determines the success of hematopoietic stem cell transplantation (HSCT. Temporal differences in the recovery of lymphocyte subsets and the factors influencing this recovery are important variables that affect a patient's posttransplant immune reconstitution, and therefore require investigation. &lt;b&gt;Methods:&lt;/b&gt; The time taken to achieve lymphocyte subset recovery and the factors influencing this recovery were investigated in 59 children who had undergone HSCT at the Department of Pediatrics, The Catholic University of Korea Seoul St. Mary's Hospital, and who had an uneventful follow-up period of at least 1 year. Analyses were carried out at 3 and 12 months post-transplant. An additional study was performed 1 month post-transplant to evaluate natural killer (NK cell recovery. The impact of preand post-transplant variables, including diagnosis of Epstein-Barr virus (EBV DNAemia posttransplant,on lymphocyte recovery was evaluated. &lt;b&gt;Results:&lt;/b&gt; The lymphocyte subsets recovered in the following order: NK cells, cytotoxic T cells, B cells,and helper T cells. At 1 month post-transplant, acute graft-versus-host disease was found to contribute significantly to the delay of CD16+/56+ cell recovery. Younger patients showed delayed recovery of both CD3+/CD8+ and CD19+ cells. EBV DNAemia had a deleterious impact on the recovery of both CD3+ and CD3+/CD4+ lymphocytes at 1 year post-transplant. &lt;b&gt;Conclusion:&lt;/b&gt; In our pediatric allogeneic HSCT cohort, helper T cells were the last subset to recover. Younger age and EBV DNAemia had a negative impact on the post-transplant recovery of T cells and B cells.

    2017-05-01

    Full Text Available Context Survival after allogeneic hematopoietic stem-cell transplantation (HSCT for children with hematologic malignancies including acute lymphoblastic leukemia (ALL continues to improve in part due to advancement in HLA typing and enhanced supportive care. Despite improved outcomes with HSCT, the decision to offer it in first remission (CR1 in children with ALL remains a topic of debate and uncertainty. This review aims to discuss the role of HSCT in CR1 for children with high-risk subsets of ALL in the current era. Evidence Acquisition A thorough review of the literature was performed using electronic databases: PubMed, Google Scholar, and bibliographies. Studies focusing on high-risk subsets of ALL (Primary Induction Failure, Severe Hypodiploidy, Philadelphia-chromosome positive ALL, T-Cell ALL, Infant ALL, ALL with persistent minimal residual disease (MRD, and Philadelphia-like ALL were included. Publications in non- English language were excluded. Results Based on our review of the current literature, HSCT should be considered in first remission for patients with primary induction failure, severe hypodiploidy, T-cell ALL with poor response, high-risk infant ALL, and persistently positive MRD. In contrast, HSCT in CR1 may not be warranted for patients with early T-cell progenitor ALL or Philadelphia-chromosome positive ALL. Further data are needed to make specific recommendations regarding Philadelphia-like ALL. Conclusions As our understanding of high-risk leukemia biology continues to develop, the role of HSCT in ALL CR1 will need to be revisited.

    Pediatric heart transplantation is an effective therapy to treat advanced heart failure in children. To analyze the immediate and mid-term results of pediatric patients listed for heart transplantation. Registration of patients admitted to our transplant protocol between October 2001 and July 2016 were reviewed, analyzing demographic data, diagnosis, status at the time of listing, waiting time until transplantation, donor data, use of ventricular assist device, hemodynamic data, complications and global mortality. Thirthy patients where included with a mean age of 9.4 years (1 month to 15 years). The most frequent diagnosis was dilated cardiomyopathy in 24 patients (80%). The status was I (urgency) in 19 cases and II in 11 cases. Ten patients died on the waiting list (33.3%) at an average of 52 days (13-139 days). Fourteen were transplanted (46.7%), with a waiting time of 199.6 days (4-586 days). Nine patients required mechanical support (30%). All patients received triple association of immunosuppression. One patient died 16 days post transplant due to primary graft failure (7.1%). The average follow-up was 43 months (0.5-159 months). Two patients died later on (82 and 55 months), both due to secondary rejection because of voluntary cessation of immunosuppressive therapy. Survival at 1 and 5 years was 93% and 74%, respectively. Our program has successfully transplanted 50% of patients enrolled, with good medium-term survival. A significant proportion of patients were listed as a medical emergency and 34.5% died on the waiting list.

    Full Text Available Abstract Background The binding of CXCR4 with its ligand (stromal-derived factor-1 maintains hematopoietic stem/progenitor cells (HSPCs in a quiescent state. We hypothesized that blocking CXCR4/SDF-1 interaction after hematopoietic stem cell transplantation (HSCT promotes hematopoiesis by inducing HSC proliferation. Methods We conducted a phase I/II trial of plerixafor on hematopoietic cell recovery following myeloablative allogeneic HSCT. Patients with hematologic malignancies receiving myeloablative conditioning were enrolled. Plerixafor 240 μg/kg was administered subcutaneously every other day beginning day +2 until day +21 or until neutrophil recovery. The primary efficacy endpoints of the study were time to absolute neutrophil count >500/μl and platelet count >20,000/μl. The cumulative incidence of neutrophil and platelet engraftment of the study cohort was compared to that of a cohort of 95 allogeneic peripheral blood stem cell transplant recipients treated during the same period of time and who received similar conditioning and graft-versus-host disease prophylaxis. Results Thirty patients received plerixafor following peripheral blood stem cell (n = 28 (PBSC or bone marrow (n = 2 transplantation. Adverse events attributable to plerixafor were mild and indistinguishable from effects of conditioning. The kinetics of neutrophil and platelet engraftment, as demonstrated by cumulative incidence, from the 28 study subjects receiving PBSC showed faster neutrophil (p = 0.04 and platelet recovery >20 K (p = 0.04 compared to the controls. Conclusions Our study demonstrated that plerixafor can be given safely following myeloablative HSCT. It provides proof of principle that blocking CXCR4 after HSCT enhances hematopoietic recovery. Larger, confirmatory studies in other settings are warranted. Trial registration ClinicalTrials.gov NCT01280955

    Due to the continuing shortage of cadaveric donors in Japan, ABO-incompatible living kidney transplantation (LKT) is being performed. It is well known that highly sensitized patients with positive panel reactive antibodies (PRA) often present with acute rejection. Therefore, we examined the impact of a positive PRA on the results of ABO-incompatible LKT. One hundred seventy-seven recipients underwent ABO-incompatible LKT between January 1989 and March 2003. Of these patients, 37 who had been examined for PRA before transplantation were included in this study. There were 25 men and 12 women of mean age 37.3 years. Plasmapheresis was performed to remove anti-ABO antibodies before transplantation. During the induction phase, methylprednisolone, azathioprine, or mycophenolate mofetil and cyclosporine or tacrolimus were used for immunosuppression. Splenectomy was performed at the time of kidney transplantation in all patients. PRA was measured using FlowPRA by flow cytometer. Eight of the 37 patients had a positive PRA before transplantation (class I, 5; class II, 1; class I and class II, 2). The incidence of acute rejection was 37.9% in the patients with a negative PRA and 37.5% in patients with a positive PRA. One patient with a negative PRA and one patient with a positive PRA lost grafts due to acute rejection. Positive PRA may not increase the incidence of acute rejection in ABO-incompatible LKT because plasmapheresis and splenectomy are performed to eliminate anti-ABO antibody.

    Abstract The aim of the study is to determine whether HLA-haploidentical-related donor (HRD) transplant can achieve equivalent outcomes and have stronger GVL compared to HLA-matched sibling donor (MSD) and HLA-matched unrelated donor (MUD) transplants. A total of 355 consecutive patients with acute leukemia undergoing allogeneic transplant at our single institute between March 2008 and March 2014 were enrolled in this retrospective investigation. Of the 355 patients, 96 cases received HRD, 153 MSD, and 106 MUD transplants. HRD transplant was associated with higher incidences of grade II to IV aGVHD (40.6%) compared with MSD (23.5%, P = 0.002) and MUD transplants (34.0%, P = 0.049), whereas incidences of grade III to IV aGVHD (11.4%, 7.8%, 10.5%, respectively; P = 0.590) and cGVHD (29.5%, 24.0%, 29.5%, respectively; P = 0.538) did not differ among 3 groups. Five-year relapse rates were 19.2%, 26.8%, and 23.0% in 3 groups, respectively (P = 0.419). However, of 206 high-risk patients, the relapse rate in HRD transplant was lower than in MSD transplant (23.8% vs 41.9%, P = 0.026). Multivariate analysis showed that HRD had beneficial impact on relapse (for MSD: P = 0.006). Five-year transplant-related mortality was lower in MSD transplant compared with those in HRD (17.3% vs 26.4%, P = 0.041) and MUD transplants (17.3% vs 24.1%, P = 0.037). Five-year overall survival were 60.4%, 64.6%, and 61.0%, respectively, in HRD, MSD, and MUD groups (P = 0.371); 5-year disease-free survival were 59.6%, 58.8%, and 54.9%, respectively (P = 0.423). Our results suggest that HRD transplant results in outcomes equivalent to MSD and MUD transplants. HRD might carry a superior GVL effect compared to MSD for high-risk patients. PMID:26986108

    Living donor liver transplantation (LDLT) is an alternative to conventional transplantation given its excellent results. The aim of this study is to evaluate long-term outcomes in LDLT recipients. 100 consecutive THDV recipients from the Hospital Clínic of Barcelona from March 2000 to October 2015 were included. The main indication for transplantation was end-stage liver disease (58%) followed by hepatocellular carcinoma (41%). 95% of grafts consisted of the right liver of the donor and the 5% of the left liver. After a median follow-up of 65.5 months, patient and graft survival at 1, 3, and 5 years was 93%, 80% and 74% and 90%, 76%, and 71%, respectively. The overall re-transplant rate was 9%. The most common long-term complication was biliary stenosis (40%) with an average time of onset of 13.5±12 months, with repeated admissions and an average of 1.9±2 endoscopic procedures and 3.5±3 Radiological procedures per patient. The definitive treatment was radiological dilation in 40% of cases, surgical intervention in 22.5% and re-transplantation in 7.5%. Given the long-term results, LDLT is confirmed as an alternative to conventional transplantation. However, the high rate of late biliary complications involves repeated admissions and invasive treatments that, while not compromising survival, can affect the patient's quality of life.

    Full Text Available Background. Allogeneic haemopoietic stem cell transplant (Allo-HSCT is a specialised and costly intervention, associated with significant morbidity and mortality. It is used to treat a broad range of paediatric conditions. South Africa (SA is an upper middle-income country with limitations on healthcare spending. The role of paediatric Allo-HSCT in this setting is reviewed. Objectives. To review paediatric patients who underwent Allo-HSCT at the Groote Schuur Hospital/University of Cape Town Private Academic Hospital transplant unit in Cape Town, South Africa, and received post-transplant care at Red Cross War Memorial Children’s Hospital, over the period January 2006 - December 2014 in respect of indications for the transplant, donor sources, conditioning regimens, treatment-related morbidity and overall survival (OS. Methods. A retrospective analysis of patient records was performed and a database was created in Microsoft Access. Descriptive analyses of relevant demographic, clinical and laboratory data were performed. Summary statistics of demographic and clinical parameters were derived with Excel. OS was calculated from the date of transplant to the date of an event (death or last follow-up using the Kaplan-Meier method in Statistica. Results. A total of 48 children received Allo-HSCT: 24 for haematological malignancies, 20 for non-oncological haematological conditions, 3 for immune disorders and 1 for adrenoleukodystrophy. There were 28 boys (median age 7.5 years and 20 girls (8.5 years. There were 31 sibling matched peripheral-blood stem cell (PBSC transplants and 1 maternal haploidentical PBSC transplant. Stem cells were mobilised from bone marrow into peripheral blood by administering granulocyte-colony stimulating factor to donors. PBSCs were harvested by apheresis. Eight patients received 10/10 HLA-matched grafts from unrelated donors. Six were PBSC grafts and 2 were bone marrow grafts. Three of the unrelated PBSC grafts were from

    In the first portion of this work, 1,2,3,3,4,4-hexafluoro-1,2-bis[4-(dimethylhydroxysilyl)phenoxy]cyclobutane and 1,2,3,3,4,4-hexafluoro-1,2-bis[3-(dimethylhydroxysilyl)phenoxy]cyclobutane were prepared and homopolymerized to afford polymers with excellent thermal stability and Tgs of 27 C and -12 C, respectively. Despite the moderately high wt% of fluorin in the polymer structure (23.8%), these polymers had poor fuel resistance. In fact, swelling measurements indicate that these polymers had apparent solubility parameters of about 18.2 J (exp 1/2) m (exp -3/2) (toluene). Copolymerization of the disilanol monomers with fluorosilicone monomers afforded copolymers containing 20-30 wt% of the perfluorocyclobutane-containing structure displayed adequate fuel resistance, enhanced thermal stability, and a Tg low enough to meet the requirements of a High Speed Civil Transport (HSCT) fuel tank sealant. In the second part of this work, trifluorovinylether-terminated oligomers were prepared and polymerized via cyclodimerization. Initially, an alpha, omega-silanol-terminated fluorosilicone was endcapped with trifluorovinylether end groups via a two-step synthetic sequence. The oligomer was thermally cyclodimerized to a polymer that displayed thermal stability similar to that of a fluorosilicone homopolymer. Second, 1,3-bis[4-trifluorovinyl(oxy)phenyl]-1,3-(3,3,3-trifluoropropyl)dimethyldisiloxane and 1,3-bis{3-trifluorovinyl(oxy)phenyl]-1,3-(3,3,3-trifluoropropyl)dimethyldisiloxane were prepared and cyclodimerized to afford polymers that contained pendant trifluoropropyl groups. The pendant trifluoropropyl groups did enhance solvent resistance in aliphatic hydrocarbon solvents, however, no improvement was observed in aromatic hydrocarbon solvents. These polymers also displayed excellent thermal stability. In the last part of this work, a series of monomers was prepared by the DCC-promoted esterification of 4-[trifluorovinyl(oxy)benzoic acid with alpha, omega

    To evaluate outcome in the first generation of children with end-stage heart disease to whom heart transplantation was available. Retrospective review of all 135 Swedish children heart transplantation 1989-2009, followed to December 31, 2009, including 74 (55%) with cardiomyopathy and 61 (45%) with congenital heart disease; 34 (25%) were infants (heart transplantation was 1:17,300 (11 patients who improved were omitted from outcome analysis). Waiting-list mortality was 31% (44% in infants). Median waiting time in 82 transplanted patients was 57 days (0-585 days). Post-transplant follow-up time was median 5.9 years (0.03-20.1 years), and actuarial survival was 92% at 1 year, 82% at 5 years, 76% at 10 years and 58% at 15 years. Survival after listing was 64% at 1 year, 58% at 5 years, 52% at 10 years and 40% at 15 years. Post-transplant complications included rejections (34%), malignancies (12%), renal failure (8%), coronary artery vasculopathy (6%) and re-transplantation (5%). Among 64 survivors, 84% were free of complications affecting prognosis. High waiting-list mortality and post-transplant attrition precluded 60% of this pioneer population from reaching adulthood. Functional status in survivors is generally good. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

    To investigate the pathogenesis and therapy of hydronephrosis after hematopoietic stem cell transplantation (HSCT). From March 2004 to March 2014, 23 patients with hydronephrosis after HSCT were identified. With these data, the pathogenesis of hydronephrosis after HSCT were analyzed. According to the surgical intervention of hydronephrosis and ureteral dialation of ureteral stricture, the patients were divided into two groups, rank-sum test and exact probability test were used to evaluate whether there were significant differences in the time of hemorrhagic cystitis (HC) occurred, ureteritis and viremia. HC, ureteritis, ureteral stenosis were all the causes of hydronephrosis after HSCT. In this study, 69.6% (16/23) of the patients suffered from HSCT were cured by conservative treatment, 30.4% (7/23) by surgical intervention, and 13.0% (3/23) by insertion DJ stent or nephrostomy.Of the patients [17.4% (4/23)] who suffered ureteral stenosis, 2 were cured after the balloon dialation of ureter, 1 needed DJ tube long-term insertion, and 1 was still followed-up. rank-sum test and exact probability test results showed that the patients who needed surgical intervention might suffer from HC later than other patients, and their incidences of viremia and ureteritis were higher, but the differences between the two groups were not statistically significant (P = 0.524, P = 0.169, and P = 0.124, respectively). The results also showed that the ureteritis incidences of the patients who suffered from ureteral stricture and needed ureteral dialation were higher than that of the other patients, and the difference between the two groups was statistically significant (P = 0.024). The patients who needed ureteral dialation suffered from HC later and their incidences of viremia was higher, but the differences between the two groups were not statistically significant (P = 0.73 and P = 0.27). HC, ureteritis and ureteral stenosis may cause hydronephrosis after HSCT. Patients may treated by

    Full Text Available Autologous transplantation of melanocyte/melanocytes bearing epidermis for vitiligo can be done by mini-punch grafting (MPG, suction blister epidermal grafting (SBEG, thin split -thickness skin grafting (TSTG, transplantation of basal cell layer enriched suspension and cultured epithelial/melanocyte transplantation. To date no comparative study of these transplantation procedures has been published. Comparison of different studies carried out at different centers may be difficult in the absence of uniform evaluation criteria. In most of the published studies, the results were evaluated in terms of extent of pigmentation. Complictions and color match were evaluated separately. This approach, however, may not give a fair idea about the results. We have developed a scoring system with holistic approach considering the extent of pigmentation, color match and the complications of both the donor and the recipient areas, all taken together. In the scoring system, the score for individual criteria was multiplied with a factor, the value of which was decided on the basis of relative importance of each criteria. The use of this scoring system is exemplified in twelve patients who underwent TSTG, SBEG and MPG. In the scoring system the results were judged as excellent and fair in 3 patients each, as good in 4 patients and as poor in 2 patients.

    Full Text Available It has been suggested that the research priorities of those funding and performing research in transplantation may differ from those of end service users such as patients, carers and healthcare professionals involved in day-to-day care. The Kidney Transplant Priority Setting Partnership (PSP was established with the aim of involving all stakeholders in prioritising future research in the field.The PSP methodology is as outlined by the James Lind Alliance. An initial survey collected unanswered research questions from patients, carers and clinicians. Duplicate and out-of-scope topics were excluded and the existing literature searched to identify topics answered by current evidence. An interim prioritisation survey asked patients and professionals to score the importance of the remaining questions to create a ranked long-list. These were considered at a final consensus workshop using a modified nominal group technique to agree a final top ten.The initial survey identified 497 questions from 183 respondents, covering all aspects of transplantation from assessment through to long-term follow-up. These were grouped into 90 unanswered "indicative" questions. The interim prioritisation survey received 256 responses (34.8% patients/carers, 10.9% donors and 54.3% professionals, resulting in a ranked list of 25 questions that were considered during the final workshop. Participants agreed a top ten priorities for future research that included optimisation of immunosuppression (improved monitoring, choice of regimen, personalisation, prevention of sensitisation and transplanting the sensitised patient, management of antibody-mediated rejection, long-term risks to live donors, methods of organ preservation, induction of tolerance and bioengineering of organs. There was evidence that patient and carer involvement had a significant impact on shaping the final priorities.The final list of priorities relates to all stages of the transplant process, including

    To assess the role of hematopoietic SCT (HSCT) in adult ALL patients with central nervous system involvement at diagnosis, we retrospectively analyzed 90 patients who underwent autologous HSCT (auto-HSCT group; n=27) or allogeneic HSCT (allo-HSCT group; n=63) and reported to the Société Française de Greffe de Moelle et de Thérapie Cellulaire registry between 1994 and 2008. At the time of transplantation, 67 patients (74%) were in first CR, 15 (17%) in CR2 and 8 (9%) with progressive disease. The 5-year probabilities of overall survival (OS) and disease-free survival (DFS) were 52% and 46% for the allo-HSCT and 37% and 33% for the auto-HSCT groups, respectively (P=NS). The TRM at 5 years was 29.8% for the allo-HSCT group and 3.7% for the auto-HSCT group. Using univariate analysis, a time for transplantation of transplantation, the use of high-dose TBI and the number of the transplant were all determined to be prognostic factors for improved DFS and OS probabilities. Using multivariate analysis, we demonstrated that both the use of high-dose TBI and the remission status had a favorable impact on OS. Although the DFS and OS were better in the allo-HSCT group, the differences were not statistically significant.

    disease. Younger patients with high-risk criteria may benefit with a more aggressive treatment that includes hematopoietic stem cell transplantation (HSCT. Autologous transplantation, despite of the encouraging results with cases of molecular and/or cytogenetic remission and low mortality rates, does not present a plateau in survival curves and has a high relapse rate. Allogeneic transplantations using myeloablative regimens, have high toxicity and mortality rates, but also demonstrate the graft-versus-leukemia effect that increases the possibility of cure of these individuals. So the option of allogeneic transplants for patients with CLL is directed to conditioning using non-myeloablative regimens, which can also be applied to older patients or those with comorbidities, and maintain a potential graft-versus-leukemia effect. The identification of patients who may benefit from these procedures and the characterization of new prognostic markers remain the subjects of many clinical studies and were the objective of the group responsible for discussing guidelines for CLL of the consensus on HSCT SBTMO. Thus we believe that HSCT for CLL should follow the criteria of the EBMT. When a sibling donor is available the best option is allogeneic HSCT with a myeloablative regimen. The strategy of unrelated allogeneic or autologous HSCT must be considered as a second option when no donor is available, for special situations and clinical trials.

    Simultaneous kidney-pancreas transplantation for patients with type 1 diabetes and end-stage chronic renal disease is widely performed. However, the rate of surgical morbidity from pancreatic complications remains high. The aim of this study was to describe the development and results of a new program, from the point of view of the pancreatic surgeon. We analyzed 53 simultaneous kidney-pancreas transplantations performed over a period of seven years (2009-2016), with a median follow up of 39 months (range: 1-86 months). Out of the total of this series, two patients died: one patient because of cardiac arrest immediately after surgery; and another patient due to traffic accident, complicated by pneumonia. Among the 51 living patients, two grafts were lost: one due to chronic rejection four years after transplantation; and the other due to arterial thrombosis 20 days after transplantation (the only case requiring transplantectomy). In ten patients, one or more re-operations were necessary due to the following: graft pancreatitis (n=4), small intestinal obstruction (n=4), arterial thrombosis (n=1), fistula (n=1) and hemoperitoneum (n=1). Overall patient and graft survival rates after 1, 3 and 5 years were 98, 95 and 95% and 96, 93 and 89%, respectively. This study has shown that the results of a new pancreas transplant program, which relies on the previous experience of other groups, do not demonstrate a learning curve. Adequate surgeon education and training, as well as the proper use of standardized techniques, should ensure optimal results. Copyright © 2018 AEC. Publicado por Elsevier España, S.L.U.

    The prevalence of hemoglobinopathies in Spain is increasing as a result of immigration. Thalassemia major presents with chronic hemolytic anemia that requires regular red blood cell transfusions within the first year of life. Patients with sickle cell disease suffer from chronic anemia, vasculopathy and progressive damage in almost any organ. There is decreased life expectancy in both conditions. Allogeneic hematopoietic stem cell transplantation represents the only potentially curative option. Seventeen patients (fourteen thalassemia major, and three sickle cell disease) underwent allogeneic hematopoietic stem cell transplantations. In the thalassemia group, nine donors were HLA-geno-identical siblings, two were partially matched related donors (one HLA allele mismatch), and three unrelated donors. All three patients with sickle cell disease were transplanted from HLA-geno-identical siblings. The source of stem cells was bone marrow in sixteen cases. Median patient age at transplant was six years (range: 1-16) in the thalassemia group, and twelve years (range: 8-15) in the sickle cell disease group. The graft was successful in all patients. Secondary graft rejection was observed in two thalassemia patients rendering them dependent on blood transfusions. Complete chimerism was observed in thirteen patients and, although mixed chimerism occurred in two, with all of them showing normal hemoglobin levels after transplantation and not requiring further transfusion support. Patients affected by sickle cell disease did not present with new vaso-occlusive crises, and stabilization of pulmonary and neurological function was observed. Chronic graft-versus-host disease was detected in three patients affected by thalassemia, and hypogonadotrophic hypogonadism in five patients. We conclude that for thalassemia major and sickle cell disease, allogenic hematopoietic stem cell transplantation from HLA-geno-identical siblings offers a high probability of complication-free survival

    Pain is common for hematopoietic stem cell transplant (HSCT) patients and may be experienced pre-transplant, acutely post-transplant, and for months or years following transplant. HSCT patients with persistent pain may be at risk for poor quality of life following transplant; however, the impact of pre-transplant pain on quality of life post-transplant is not well understood. Self-efficacy for chronic disease management is associated with quality of life among cancer patients and may impact quality of life for HSCT patients. The primary aim was to examine the effect of pre-transplant pain and self-efficacy on quality of life domains in the year following transplant. One hundred sixty-six HSCT patients completed questionnaires providing information on pain, self-efficacy, and quality of life prior to transplant, at discharge, and 3-, 6-, and 12-months post-transplant as part of a longitudinal, observational study. Linear mixed modeling examined the trajectories of these variables and the effect of pre-transplant pain and self-efficacy on post-transplant quality of life. Pain and social and emotional quality of life remained stable in the year following transplant while self-efficacy and physical and functional quality of life improved. Pre-transplant pain was significantly related to lower physical well-being post-transplant. Lower pre-transplant self-efficacy was related to lower quality of life across all domains post-transplant. Above and beyond the effect of pre-transplant pain, self-efficacy for managing chronic disease is important in understanding quality of life following transplant. Identifying patients with pain and/or low self-efficacy pre-transplant may allow for early intervention with self-management strategies.

    To evaluate the prevalence of positive microbiology results (culture and/or Gram stain) in donor cornea tissue with newer transplant methods and to assess if the results subsequently correlate with higher incidence of clinical infection. A retrospective review of the microbiology records of 569 consecutive corneal transplants from July 2006 through July 2010 was performed to evaluate positive microbiology results in routine evaluation of cornea donor tissue. Microbiologic results were available for 544 of 569 transplants. The remaining 25 cases did not have specimens submitted for microbiologic analysis. In cases with results available, 46 (8.5%) positive reports occurred. In 10 of the 46 cases, Gram stain results were positive with subsequent negative cultures. Analysis revealed that the prevalence of positive results was 6 in 137 (4.4%), 14 in 127 (11.0%), and 26 in 271 (9.6%) for femtosecond laser-enabled keratoplasty, Descemet stripping automated endothelial keratoplasty, and conventional penetrating keratoplasty, respectively; 9 femtosecond deep anterior lamellar keratoplasty had no positive results. There was no significant relationship between the types of transplant procedures and the occurrence of positive microbiologic results (P = 0.08). The overall incidence of clinical infection was found to be 0.4% (2 of 569); however, only 1 case (1 of 569 or 0.2%), which was a Candida albicans infection after Descemet stripping automated endothelial keratoplasty, was attributable to the donor. Of 25 cases in which microbiology studies were not performed, none developed a clinical infection. Prevalence of positive microbiologic results and subsequent infections do not appear to be increased with the method of donor handling used for newer techniques for keratoplasty.

    ABSTRACT Hematopoietic stem cell transplant (HSCT) recipients should be routinely revaccinated after transplantation. We evaluated the difficulties met in the revaccination program and how a prospective and tailored follow-up could help to overcome these obstacles. HSCT recipients (n=122) were prospectively followed up and categorized into Group 1 (n=72), recipients who had already started the revaccination program, and Group 2 (n=50), recipients starting their vaccines. Whenever a difficulty...

    Allogeneic hematopoietic stem cell transplantation (HSCT) has become an established treatment modality for various hematological diseases. However, in allogeneic HSCT, patients often suffer from severe gastrointestinal complications caused by the conditioning regimen and acute/chronic graft-versus-host disease, which requires support by multidisciplinary nutritional support teams (NST). In addition, pretransplantation nutritional status can affect the clinical outcome after allogeneic HSCT. Therefore, it is important to refer the patient to a NST when becoming aware of nutritional problems before allogeneic HSCT. It is also important to follow nutritional status over the long term, as patients often suffer from various nutritional problems, such as malnutrition and metabolic syndrome, even late after allogeneic HSCT. In summary, NST can contribute to the improvement of nutritional status and possibly prognosis at every stage before and after allogeneic HSCT. Here, we aim to give a comprehensive overview of current understanding about nutritional support in allogeneic HSCT and try to provoke a constructive discussion to stimulate further investigation.

    Full Text Available Abstract Background Antifungal prophylaxis is currently regarded as the gold standard in situations with allo-genetic hematopoietic stem cell transplantation (allo-HSCT. However, the epidemiological information regarding prophylaxis of invasive fungal diseases (IFDs is not clear in China. Methods We report the first large-scale (1053 patients observational study of the prophylaxis and management of IFDs among patients with allo-HSCT in China. Results The incidence rates of IFD after primary antifungal prophylaxis (PAP, secondary antifungal prophylaxis (SAP, and non-prophylaxis were 22.7 vs. 38.6 vs. 68.6 %, respectively (P = 0.0000. The median time from transplantation to IFD was 45 days in PAP patients, 18 days in SAP patients, and 12 days in non-prophylaxis patients. Aspergillus spp. represents the most common type of fungal infection. Independent risk factors for IFD in allo-HSCT patients with PAP were age, having human leukocyte antigen (HLA-haploidentical or matched unrelated donor, decreased albumin levels, and the use of itraconazole as the prophylactic antifungal agent. Among SAP transplant recipients, there was no significant risk factor for IFDs. The incidence rates of overall survival (OS in the PAP, SAP, and no prophylaxis groups were 85.07, 78.80, and 74.82, respectively (P = 0.01. Conclusions This observational study indicates that prophylaxis of IFD is helpful to reduce the incidence of IFDs and improve the OS of patients after allo-HSCT.

    The immunomodulatory role of human leukocyte antigen (HLA)-E in hematopoietic stem cell transplantation (HSCT) has not been extensively investigated. To this end, we genotyped 509 10/10 HLA unrelated transplant pairs for HLA-E , in order to study the effect of HLA-E as a natural killer (NK)-alloreactivity mediator on HSCT outcome in an acute leukemia (AL) setting. Overall survival (OS), disease free survival (DFS), relapse incidence (RI) and non-relapse mortality (NRM) were set as endpoints. Analysis of our data revealed a significant correlation between HLA-E mismatch and improved HSCT outcome, as shown by both univariate (53% vs 38%, P =0.002, 5-year OS) and multivariate (hazard ratio (HR)=0.63, confidence interval (CI) 95%=0.48-0.83, P =0.001) analyses. Further subgroup analysis demonstrated that the positive effect of HLA-E mismatch was significant and pronounced in advanced disease patients (n=120) (5-year OS: 50% vs 18%, P =0.005; HR=0.40, CI 95%=0.22-0.72, P =0.002; results from univariate and multivariate analyses, respectively). The study herein is the first to report an association between HLA-E incompatibility and improved post-transplant prognosis in AL patients who have undergone matched unrelated HSCT. Combined NK and T cell HLA-E-mediated mechanisms may account for the better outcomes observed. Notwithstanding the necessity for in vitro and confirmational studies, our findings highlight the clinical relevance of HLA-E matching and strongly support prospective HLA-E screening upon donor selection for matched AL unrelated HSCTs.

    2014-06-01

    Full Text Available Hematopoietic stem cell transplantation (HSCT is the definite cure for many hematological diseases. With the increasing indications for HSCT and its relatively low cost in Indian subcontinent, an increasing number of patients are opting for this procedure. We retrospectively analyzed the cost of one hundred sixty two HSCTs done at our center in the last three years. The median cost of autologous transplant was INR 7,52,294 (USD, $ 12,500 (range INR 6,19,850-14,17,212 and the median cost of allogenic transplant was INR 10,74,881 ($18,000 (range INR 6,49,944-23,82,227. The cost of HSCT is cheaper here compared to that in developed countries and success rates are nearly equivalent. The major factors contributing to the cost are related to the complications post-transplant mainly infections and graft versus host disease, which are also the reasons for the increased stay in the hospital.

    The clinical outcome of allogeneic HSCT was retrospectively analyzed in eight patients with CHS. In total, six of these eight patients are alive. Four of five patients transplanted with MAC achieved prompt engraftment, and three of the four patients, including two patients with AP before transplant, are alive without disease. In contrast, three patients transplanted with RIC without active AP disease achieved prompt engraftment and survive long term. RIC-HSCT might be an alternative treatment for CHS similar to other types of HLH, at least for patients without active AP disease. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2012-02-01

    Full Text Available Objective  The present report describes the clinical effects of parental haploidentical hematopoietic stem celltransplantation (hi-allo-HSCT in the treatment of hematologic diseases. Methods  A total of 45 patients received parental hiallo-HSCT from July 2007 to January 2011. The therapeutic effects and complications were observed. Results  Engraftment was successful in a total of 43 patients. Implantation failed in 2 patients. The incidence of the graft versus host disease (GVHD was 62.2%. The incidence of acute GVHD was 40.0%, and chronic GVHD occurred in 22.2% of the patients. The incidence of GVHD was lower when the father was the donor compared with the mother was the donor. The incidence of GVHD was related to the age of the donor and the number of HLA matching sites. In addition, infections observed in the present study were mainly blood-borne with cytomegalovirus as the invader and lung infections. During the follow-up period of 6 months to 4 years, six patients died in the 43 patients with successful implantation. The major cause of death was infection and a relapse of their original disease. The disease free survival (DFS rate was 86.7%. Seven patients additionally received umbilical cord blood, their efficacy in the transplantation seemed better than those who received parental stem cells only, as hematopoietic reconstruction was faster and the incidence of GVHD accounted for only 7.14% of the total incidence rate. Conclusions  Parental hi-allo-HSCT is an effective treatment for hematologic diseases. A young male donor with more HLA matching sites is recommended to prevent GVHD and infection. The combination of parental hi-allo-HSCT and umbilical cord blood transplantation could result in positive effects with faster hematopoietic reconstruction and a lower incidence of GVHD.

    The role of ganciclovir as HHV-6 prophylaxis in unrelated HSCT setting remains controversial. We performed an eight-yr retrospective review of patients received unrelated HSCT from January 2000 to September 2008. From January 2002, ganciclovir prophylaxis 5 mg/kg twice daily for seven days for all unrelated HSCT before transplant was adopted. The prevalence of HHV-6 encephalitis was studied before and after the change in policy. Fifty-four unrelated HSCT were performed from January 2000 to September 2008. Four cases (7.4%) of HHV-6 encephalitis were diagnosed. All of them were due to variant B infection. Two cases out of 16 cases (12.5%) were diagnosed before adoption of the policy; two cases out of 38 cases (5.3%) were diagnosed afterward. All of them were unrelated UCB transplant recipients. They were all seropositive to HHV-6 before transplant. Two cases complicated with significant residual neurological deficit and refractory seizure. The other two cases died of other transplant-related mortalities. We conclude that HHV-6 encephalitis is still a rare complication of unrelated HSCT and may be more common in unrelated UCB transplant. Routine use of ganciclovir as HHV-6 prophylaxis in all unrelated HSCT recipients may not be justified but may have a role in unrelated UCB transplant. Copyright (c) 2009 John Wiley & Sons A/S.

    Full Text Available Introduction. Nowadays anti-inflammatory and immunosuppressive therapy has significantly improved the quality of life and prognosis of rheumatoid arthritis (RA. Nevertheless, there are still many patients with progressive rheumatoid inflammation, resulting in the destruction of joints. Cell therapy seems like a promising direction in rheumatology. The aim of our research was to evaluate the efficacy of fetal chondrocyte transplantation in patients with RA.Methods. We examined 60 patients with rheumatoid arthritis (I - III stages between 20 and 63 years of age. They were divided into 2 groups: the first group underwent the fetal chondrocytes transplantation (n = 40, and the second was a control group who got conservative therapy (n = 20. Donor cells were taken from the chondrogenic layer of the humerus or femur heads and hip condyles of human embryos in gestation for 17-20 weeks. A suspension of fetal chondrocytes injected into affected areas of the articular surfaces under X-ray control. Cell viability was determined before the injection. Efficacy of the therapy was assessed by clinical, instrumental, and laboratory tests. This clinical trial was allowed by The Ministry of Public Health and Ethics Committee. All of our patients gave informed consent for the fetal chondrocytes transplantation.Results. Evaluation of the clinical manifestations of RA in the first group of patients showed 3.7 times decrease in pain and 1.6 times relief of synovitis. Complete reduction of contracture was observed in 82% of patients in the first group. Morphometric changes in X-ray demonstrated inhibition of the destruction in articular cartilage and surfaces of bones after transplantation of fetal chondrocytes. The dynamics of morphological changes in synovium showed 2.5 times reduction of the inflammatory reaction. Transplantation of fetal chondrocytes led to a significant reduction in ESR, CRP, fibrinogen , γ-globulin after a period of 12 months (p < 0

    The high morbidity and mortality associated with invasive fungal infections (IFIs) provide the rationale for antifungal prophylaxis in immuno-compromised pediatric patients undergoing hematopoietic stem cell transplantation (HSCT). Caspofungin and micafungin are antifungal agents of interest for prophylaxis of IFIs because of their potency against Candida and minimal toxicity or interactions with other drugs. Few studies have demonstrated the safety and efficacy of such echinocandins as prophylaxis for IFIs in patients undergoing HSCT. This retrospective cohort study compared caspofungin and micafungin for prevention of IFIs in 93 pediatric patients undergoing HSCT for oncological or non-oncological disease. The observation began with the first dose of antifungal agent and ended 3 months after transplantation. Patients in the micafungin group had a higher overall treatment success rate of 87.2 versus 84.8% in the caspofungin group, but the difference was not significant. There were no statistically significant differences in the incidence or type of proven/probable IFIs between the 2 groups. The low incidence of death did not differ statistically between the groups. Patients in the caspofungin group presented more frequently with fever, during and after neutropenia. In both groups, we observed an expected worsening of blood chemistry parameters. There were no adverse events definitely attributable to the two antifungal agents. These results demonstrate good efficacy and tolerability for caspofungin and micafungin. However, better results with respect to the incidence and resolution of fever in the micafungin group may suggest its use in preference to that of caspofungin.

  3. Potential for Sonic Boom Reduction of the Boeing HSCT

    Science.gov (United States)

    Haglund, George T.

    1999-01-01

    The HSR sonic boom technology program includes a goal of reducing the objectionable aspects of sonic boom. Earlier HSCT sonic boom studies considered achieving significant sonic boom reduction by the use of arrow-wing planforms and detailed shaping of the airplane to produce shaped waveforms (non N-waves) at the ground. While these design efforts were largely successful, the added risk and cost of the airplanes were judged to be unacceptable. The objective of the current work is to explore smaller configuration refinements that could lead to reduced sonic boom impact, within design and operational constraints. A somewhat modest target of 10% reduction in sonic boom maximum overpressure was selected to minimize the effect on the configuration performance. This work was a joint NASA/Industry effort, utilizing the respective strengths of team members at Boeing, NASA Langley, and NASA Ames. The approach used was to first explore a wide range of modifications and airplane characteristics for their effects on sonic boom and drag, using classical Modified Linear Theory (MLT) methods. CFD methods were then used to verify promising, modifications and to analyze modifications for which the MLT methods were not appropriate. The tea m produced a list of configuration changes with their effects on sonic boom and, in some cases, an estimate of the drag penalty. The most promising modifications were applied to produce a boom-softened derivative of the baseline Boeing High Speed Civil Transport (HSCT) configuration. This boom-softened configuration was analyzed in detail for the reduce sonic boom impact and also for the effect of the configuration modifications on drag, weight, and overall performance relative to the baseline.

    Long-term catheters are often necessary for outpatient care after an allogeneic hematopoietic stem cell transplantation (HSCT), However, there is paucity of data on the use of peripherally inserted central catheter (PICC) in post-HSCT setting. We prospectively evaluated the systematic use of PICC in 37 consecutive patients returning home after HSCT. In 6 out of 37 patients, the PICC was exclusively used for weekly blood controls. In 31 patients, the PICC line was used at home for hydration (18), antibiotics (3), intravenous human Ig (7), transfusions (10), extracorporeal photopheresis (3), chemotherapy (2), artificial nutrition (1), and/or palliative care (1). PICC complications were reported in ten patients (27%), causing eight PICC removals. At the end of the study, 35 patients had their PICC removed. PICCs were used with a median duration of 67 days. Reasons for removal were that PICC was not considered to be useful any longer (16), suspicion of infection (inflammation without documentation) (5) or infection (2), patient's wish (4), death (4), accidental withdrawal (2), puncture site bleeding (1), and catheter change due to extracorporeal photopheresis (1). Three venous thromboses were reported (8%), requesting one PICC removal because of associated infection. In other cases, an antithrombotic treatment was initiated. Although the number of patients included in the study was small, our results suggest that PICC is a safe long-term venous access for home care after HSCT.

    2015-08-01

    Full Text Available Hematopoietic stem cell transplantation (HSCT is an established therapeutic procedure for several congenital and acquired disorders, both malignant and nonmalignant. Despite the great improvements in HSCT clinical practices over the last few decades, complications, such as graft vs. host disease (GVHD and sinusoidal obstructive syndrome (SOS, are still largely unpredictable and remain the major causes of morbidity and mortality. Both donor and patient genetic background might influence the success of bone marrow transplantation and could at least partially explain the inter-individual variability in HSCT outcome. This review summarizes some of the recent studies on candidate gene polymorphisms in HSCT, with particular reference to pediatric cohorts. The interest is especially focused on pharmacogenetic variants affecting myeloablative and immunosuppressive drugs, although genetic traits involved in SOS susceptibility and transplant-related mortality are also reviewed.

    Highlights: • Injection of UVB-irradiated iDCs induces alloantigen tolerance. • This alloantigen tolerance may be associated regulatory T cell induction. • Tolerant mice serve as bone marrow donors reduces GVHD to their F1 recipients in allo-HSCT. • Tolerance is maintained in F1 recipients for long time post HSCT. - Abstract: Haploidentical hematopoietic stem cell transplantation (Haplo-HSCT) has been employed worldwide in recent years and led to favorable outcome in a group of patients who do not have human leukocyte antigen (HLA)-matched donors. However, the high incidence of severe graft-versus-host disease (GVHD) is a major problem for Haplo-HSCT. In the current study, we performed a proof of concept mouse study to test whether induction of allogeneic tolerance between two different parental strains was able to attenuate GVHD in Haplo-HSCT to the F1 mice. We induced alloantigen tolerance in C3H mice (H-2k) using ultraviolet B (UVB) irradiated immature dendritic cells (iDCs) derived from the cultures of Balb/c bone marrow cells. Then, we performed Haplo-HSCT using tolerant C3H mice as donors to F1 mice (C3H × Balb/c). The results demonstrated that this approach markedly reduced GVHD-associated death and significantly prolonged the survival of recipient mice in contrast to the groups with donors (C3H mice) that received infusion of non-UVB-irradiated DCs. Further studies showed that there were enhanced Tregs in the tolerant mice and alloantigen-specific T cell response was skewed to more IL-10-producing T cells, suggesting that these regulatory T cells might have contributed to the attenuation of GVHD. This study suggests that it is a feasible approach to preventing GVHD in Haplo-HSCT in children by pre-induction of alloantigen tolerance between the two parents. This concept may also lead to more opportunities in cell-based immunotherapy for GVHD post Haplo-HSCT.

    Allogeneic hematopoietic stem cell transplantation (HSCT) offers the possibility of cure for sickle cell disease (SCD) patients. Unfortunately, the probability of finding an HLA-matched donor for SCD patients is low. HSCT from HLA-haploidentical donors using reduced intensity conditioning, unmanipulated bone marrow and post-transplantation cyclophosphamide (ptCy) has resulted in negligible toxicity but high rates of graft rejection. We hypothesized that combining ptCy with a myeloablative reduced toxicity conditioning including serotherapy to increase immune ablation would allow for better engraftment. In a pilot approach, we treated three patients with SCD (5, 8, and 20 years old) lacking a matched donor. All patients had severe disease-related complications despite standard treatment. They received unmanipulated bone marrow from parental HLA-haploidentical donors. Conditioning consisted of alemtuzumab 0.2 mg/kg/day on days -9 and -8, fludarabine 30 mg/m 2 /day on days -7 to -3, treosulfan 14 g/m 2 /day on days -7 to -5, thiotepa 2 × 5 mg/kg/day on day -4, and cyclophosphamide 14.5 mg/kg/day on days -3 and -2. GVHD prophylaxis was performed using cyclophosphamide 2 × 50 mg/kg on days +3 and +4 and mycophenolate mofetil, tacrolimus from day +5. After a follow-up of 11, 14, and 30 months, all three patients are alive and well, off immunosuppression, and without symptoms of SCD. One patient experienced mild skin GVHD grade I, none showed chronic GVHD. Asymptomatic CMV reactivation was seen in two patients. HLA-haploidentical HSCT can extend the donor pool for patients with SCD. Whether intensification of the conditioning regimen and intensive immunosuppression leads to improvement in engraftment rates while still allowing a favorable toxicity profile deserves further investigation.

    Data on 68,146 hematopoietic stem cell transplants (HSCT) (53% autologous and 47% allogeneic) gathered by 1566 teams from 77 countries and reported through their regional transplant organizations were analyzed by main indication, donor type and stem cell source for the year 2012. With transplant rates ranging from 0.1 to 1001 per 10 million inhabitants, more HSCT were registered from unrelated 16,433 than related 15,493 donors. Grafts were collected from peripheral blood (66%), bone marrow (24%; mainly non-malignant disorders) and cord blood (10%). Compared to 2006, an increase of 46% total (57% allogeneic and 38% autologous) was observed. Growth was due to an increase in reporting teams (18%) and median transplant activity/team (from 38 to 48 HSCT/team). An increase of 67% was noted in mismatched/haploidentical family HSCT. A SWOT analysis revealed the global perspective of WBMT to be its major strength and identified potential to be the key professional body for patients and authorities. The limited data collection remains its major weakness and threat. In conclusion, global HSCT grows over the years without plateauing (allogeneic>autologous) and at different rates in the four WHO regions. Major increases were observed in allogeneic, haploidentical HSCT and, to a lesser extent, in cord blood. PMID:26901703

    Full Text Available Objective: to evaluate the effectiveness of autologous chondrocyte (AC transplantation in patients after lumbar microdiscectomy in the long-term period. Materials and methods. Transplantation of cryopreserved AC has been carried out in 6 patients 3 months after lumbar microdiscectomy. Evaluation of clinical status was performed using VAS and NASS scales, before and 3 months after microdiscectomy, 1 and 2 years after AC transplantation. In the same period, there were also evaluated magnetic resonance characteristics of hydration of intervertebral disc. Results. According to magnetic resonance imaging, recovery of nucleus pulposus hydrophilicity was found in 4 of 6 patients (66.7 %, who underwent AC transplantation. Pain severity decreased significantly in the early period after microdiscectomy, and 3 months after (by the time of AC transplantation it has reduced by almost 6 times. One and 2 years after this procedure, pain continued to decline steadily. Functional status and quality of life after microdiscectomy significantly improved during first 3 months, and after transplantation they have not changed. Conclusions. Autologous chondrocyte transplantation after lumbar microdiscectomy is a safe method of surgical treatment for degenerative diseases of the spine, it helps to recover the biomechanical properties of the operated intervertebral disc.

    Epidemiology and prognosis of complications related to allogeneic hematopoietic stem cell transplant (HSCT) recipients requiring admission to intensive care unit (ICU) have not been reassessed precisely in the past few years. We performed a retrospective single-center study on 318 consecutive HSCT patients (2009-2013), analyzing outcome and factors prognostic of ICU admission. Among these patients, 73 were admitted to the ICU. In all, 32 patients (40.3%) died in ICU, 46 at hospital discharge (63%) and 61 (83.6%) 1 year later. Survivors had a significantly lower sequential organ failure assessment (SOFA) score, serum lactate and bilirubin upon ICU admission. Catecholamine support, mechanical ventilation (MV) and/or renal replacement therapy during ICU stay, a delayed organ support and an active graft versus host disease (GvHD) significantly worsen the outcome. By multivariate analysis, the worsening of SOFA score from days 1 to 3, the need for MV and the occurrence of an active GvHD were predictive of mortality. In conclusion, the incidence of HSCT-related complications requiring an admission to an ICU was at 22%, with an ICU mortality rate of 44%, and 84% 1 year later. A degradation of SOFA score at day 3 of ICU, need of MV and occurrence of an active GvHD are main predictive factors of mortality.

    Toxoplasmosis is an opportunistic infection caused by the parasite Toxoplasma gondii. The infection is severe and difficult to diagnose in patients receiving allogeneic hematopoietic stem cell transplantation (HSCT). Twelve patients receiving HSCT were monitored post-transplant, by qualitative PCR at the Children's Hospital S.A.M.I.C. "Prof. Dr. Juan P. Garrahan". The monitoring of these patients was defined by a history of positive serology for toxoplasmosis in the donor or recipient and because their hematologic condition did not allow the use of trimethoprim-sulfamethoxazole for prophylaxis. During the patients' monitoring, two of them with positive PCR results showed signs of illness by T. gondii and were treated with pyrimethamine-clindamycin. In two other patients, toxoplasmosis was the cause of death and an autopsy finding, showing negative PCR results. Four patients without clinical manifestations received treatment for toxoplasmosis because of positive PCR detection. In four patients there were no signs of toxoplasmosis disease and negative PCR results during follow-up. The qualitative PCR technique proved useful for the detection of toxoplasmosis reactivation in HSCT recipients, but has limitations in monitoring and making clinical decisions due to the persistence of positive PCR over time and manifestations of toxicity caused by the treatment.

    There are doubts about the age limit for lung donors and the ideal donor has traditionally been considered to be one younger than 55 years. The objective of this study was to compare the outcomes in lung transplantation between organs from donors older and younger than 60 years. We performed a retrospective observational study comparing the group of patients receiving organs from donors 60 years or older (Group A) or younger than 60 years (Group B) between January 2007 and December 2011. Postoperative evolution and mortality rates, short-term and mid-term postoperative complications, and global survival rate were evaluated. We analysed a total of 230 lung transplants, of which 53 (23%) involved lungs from donors 60 years of age or older (Group A), and 177 (77%) were from donors younger than 60 years (Group B). Three (5.7%) patients from Group A and 14 patients (7.9%) from Group B died within 30 days (P = 0.58). The percentage of patients free from chronic lung allograft dysfunction at 1-3 years was 95.5, 74.3 and 69.3% for Group A, and 94.5, 84.8 and 73.3% for Group B, respectively (P = 0.47). There were no statistically significant differences between Groups A and B in terms of survival at 3 years, (69.4 vs 68.8%; P = 0.28). Our results support the idea that lungs from donors aged 60-70 years can be used safely for lung transplantation with comparable results to lungs from younger donors in terms of postoperative mortality and mid-term survival. © The Author 2014.

    Vaccine-preventable diseases, especially influenza, varicella, herpes zoster, and invasive pneumococcal infections, continue to lead to significant morbidity and mortality in solid organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) recipients. We highlight guideline recommendations for the use of key vaccines in SOT and HSCT recipients and to review the latest evidence and developments in the field. Physicians should vaccinate individuals with end-stage organ disease, as vaccine seroresponse rates are higher pretransplantation. Most live attenuated vaccines continue to be contraindicated post-transplantation, but there are emerging safety profile and efficacy data to support the use of specific live attenuated vaccines, such as measles, mumps, and rubella in pediatric liver or kidney transplant recipients who are on low-level maintenance immunosuppression and without recent history of allograft rejection. An inactivated subunit varicella zoster virus vaccine is currently awaiting US Food and Drug Administration approval. While we await the safety profile and efficacy data of this subunit vaccine in transplant recipients, it will likely benefit immunocompromised individuals, including transplant recipients, because the live attenuated herpes zoster vaccine is currently contraindicated in transplant recipients and transplantation candidates receiving immunosuppression. There is currently no evidence that vaccines lead to allograft rejection in SOT recipients. Household contacts of SOT and HSCT recipients should be vaccinated per the Advisory Committee on Immunization Practices schedule and recommendations. Immunizations remain underutilized in transplantation patients. Although efficacy of vaccines in SOT and HSCT may be suboptimal, partial protection is preferred over no protection.

    Stem cell transplant can induce vasculogenesis and improve the blood supply to an ischemic region, offering hope for chronic lower extremity ischemic diseases. Bone marrow mononuclear cells are one of the sources for stem cell transplants. We sought to observe the safety and efficacy of autologous bone marrow mononuclear cells transplant for treating critical limb ischemia. Eligible patients were randomized 1:1 to receive placebo (0.9% NaCl) or 1 × 107 piece/mL bone marrow mononuclear cell transplant. For 6 months, patients' skin ulcers, ankle-brachial index, and rest pain were examined and recorded before and after treatment. Six months after the bone marrow mononuclear cells transplant, clinical symptoms like rest pain and skin ulcers gradually abated (P transplant (P Autologous bone marrow mononuclear cells transplant for treatment of patients with chronic limb ischemia is safe, effective, and feasible.

    Full Text Available Mucopolysaccharidosis type II (MPS II - Hunter syndrome is an X-linked lysosomal storage disorder caused by a deficiency in the enzyme iduronate-2 sulfatase (I2S, leading to the accumulation of the glycosaminoglycans, affecting multiple organs and systems. Enzyme replacement therapy does not cross the blood brain barrier, limiting results in neurological forms of the disease. Another option of treatment for severe MPS, hematopoietic stem cell transplantation (HSCT has become the treatment of choice for the severe form of MPS type I, since it can preserve neurocognition when performed early in the course of the disease. To date, only few studies have examined the long-term outcomes of HSCT in patients with MPS II. We describe the seven-year follow-up of a prenatally diagnosed MPS II boy with positive family history of severe MPS form, submitted to HSCT with umbilical cord blood cells at 70 days of age. Engraftment after 30 days revealed mixed chimerism with 79% donor cells; after 7 years engraftment remains at 80%. I2S activity 30 days post-transplant was low in plasma and normal in leukocytes and the same pattern is observed to date. At age 7 years growth charts are normal and he is very healthy, although mild signs of dysostosis multiplex are present, as well as hearing loss. The neuropsychological evaluation (Wechsler Intelligence Scale for Children - Fourth Edition - WISC-IV, disclosed an IQ of 47. Despite this low measured IQ, the patient continues to show improvements in cognitive, language and motor skills, being quite functional. We believe that HSCT is a therapeutic option for MPS II patients with the severe phenotype, as it could preserve neurocognition or even halt neurodegeneration, provided strict selection criteria are followed.

  20. Edge Effects along a Seagrass Margin Result in an Increased Grazing Risk on Posidonia australis Transplants.

    A key issue in habitat restoration are the changes in ecological processes that occur when fragments of habitat are lost, resulting in the persistence of habitat-degraded margins. Margins often create or enhance opportunities for negative plant-herbivore interactions, preventing natural or assisted re-establishment of native vegetation into the degraded area. However, at some distance from the habitat margin these negative interactions may relax. Here, we posit that the intensity of species interactions in a fragmented Posidonia australis seagrass meadow may be spatially dependent on proximity to the seagrass habitat edge, whereby the risk of grazing is high and the probability of survival of seagrass transplants is low. To test this, transplants were planted 2 m within the meadow, on the meadow edge at 0m, and at 2m, 10m, 30m, 50m and 100m distance from the edge of the seagrass meadow into the unvegetated sand sheet. There was an enhanced grazing risk 0-10m from the edge, but decreased sharply with increasing distances (>30m). Yet, the risk of grazing was minimal inside the seagrass meadow, indicating that grazers may use the seagrass meadow for refuge but are not actively grazing within it. The relationship between short-term herbivory risk and long-term survival was not straightforward, suggesting that other environmental filters are also affecting survival of P. australis transplants within the study area. We found that daily probability of herbivory was predictable and operating over a small spatial scale at the edge of a large, intact seagrass meadow. These findings highlight the risk from herbivory can be high, and a potential contributing factor to seagrass establishment in restoration programs.

    A 66-year-old woman with refractory angioimmunoblastic T-cell lymphoma underwent cord blood transplantation. Prior to transplantation, a serological test for Toxoplasma gondii-specific IgG antibodies was positive. On day 96, she exhibited fever and dry cough. Chest CT showed diffuse centrilobular ground glass opacities in both lungs. The reactivation of T. gondii was identified by the presence of parasite DNA in peripheral blood and bronchoalveolar lavage fluid. Moreover, brain MRI revealed a space occupying lesion in the right occipital lobe. Therefore, disseminated toxoplasmosis was diagnosed. She received pyrimethamine and sulfadiazine from day 99. The lung and brain lesions both showed improvement but the PCR assay for T. gondii DNA in peripheral blood was positive on day 133. On day 146, she developed blurred vision and reduced visual acuity, and a tentative diagnosis of toxoplasmic retinochoroiditis was made based on ophthalmic examination results. As agranulocytosis developed on day 158, we decided to discontinue pyrimethamine and sulfadiazine and the treatment was thus switched to atovaquone. Moreover, we added spiramycin to atovaquone therapy from day 174, and her ocular condition gradually improved. In general, the prognosis of disseminated toxoplasmosis after hematopoietic stem cell transplantation (HSCT) is extremely poor. However, early diagnosis and treatment may contribute to improvement of the fundamentally dismal prognosis of disseminated toxoplasmosis after HSCT.

    Full Text Available Allogeneic hematopoietic stem cell transplantation (allo-HSCT in humans, following hematoablative treatment, results in biological chimeras. In this case, the transplanted hematopoietic, immune cells and their derivatives can be considered the donor genotype, while the other tissues are the recipient genotype. The first sequel, which has been recognized in the development of chimerical organisms after allo-HSCT, is the graft versus host (GvH reaction, in which the new developed immune cells from the graft recognize the host’s epithelial cells as foreign and mount an inflammatory response to kill them. There is now accumulating evidence that this chronic inflammatory tissue stress may contribute to clinical consequences in the transplant recipient. It has been recently reported that host epithelial tissue acquire genomic alterations and display a mutator phenotype that may be linked to the occurrence of a GvH reaction. The current review discusses existing data on this recently discovered phenomenon and focuses on the possible pathogenesis, clinical significance and therapeutic implications.

  4. Myeloablative hematopoietic stem cell transplantation improves survival but is not curative in a pre-clinical model of myelodysplastic syndrome.

    Full Text Available Allogeneic hematopoietic stem cell transplantation (A-HSCT remains the only curative option for patients with myelodysplastic syndrome (MDS. We used the NUP98-HOXD13 (NHD13 murine model for MDS to study HSCT in a pre-clinical setting. NHD13 recipients transplanted with syngeneic bone marrow (S-HSCT following myeloablative irradiation showed disease remission, with normalization of peripheral blood parameters and marked decrease in circulating leukocytes derived from the MDS clone. Despite the disease remission and improved survival compared to non-transplanted NHD13 controls, all mice eventually relapsed, indicating persistence of a long-lived radio-resistant MDS clone. In an effort to induce a graft versus leukemia (GVL effect, A-HSCT with donor bone marrow that was mismatched at minor histocompatibility loci was compared to S-HSCT. Although recipients in the A-HSCT showed a lower early relapse rate than in S-HSCT, all mice in both groups eventually relapsed and died by 54 weeks post-transplant. To obtain a more significant GVL effect, donor splenocytes containing reactive T-cells were transplanted with allogeneic bone marrow. Although the relapse rate was only 20% at post-transplantation week 38, suggesting a GVL effect, this was accompanied by a severe graft versus host disease (GVHD Taken together, these findings indicate that a myeloablative dose of ionizing radiation is insufficient to eradicate the MDS initiating cell, and that transplantation of donor splenocytes leads to decreased relapse rates, at the cost of severe GVHD. We suggest that NHD13 mice represent a feasible pre-clinical model for the study of HSCT for MDS.

    Full Text Available Background. The therapeutic efficacy of allogeneic hemopoietic stem cell transplantation (HSCT largely relies on the graft-versus-leukemia (GVL effect. Uncontrolled graft-versus-host disease (GVHD is a feared complication of HSCT. Regulatory T cells (Treg are a subset of CD4+ T-helper cells believed to maintain tolerance after HSCT. It remains unclear whether low peripheral blood Treg have an impact on the risk for acute (aGVHD and chronic GVHD (cGVHD. Methods. In this paper we enumerated the CD4+CD25highCD127low Treg in the peripheral blood of 84 patients after at least 150 days from HSCT and in 20 healthy age-matched controls. Results. Although similar mean lymphocyte counts were found in patients and controls, CD3+CD4+ T-cell counts were significantly lower in patients. Patients also had significantly lower Treg percentages among lymphocytes as compared to controls. Patients with cGVHD had even higher percentages of Treg if compared to patients without cGVHD. In multivariate analysis, Treg percentages were not an independent factor for cGVHD. Conclusions. This paper did not show a relation between deficient peripheral blood Treg and cGVHD, therefore cGVHD does not seem to occur as a result of peripheral Treg paucity.

    Oral mucositis is a chief complication in patients undergoing hematopoietic stem cell transplantation (HSCT). It is considered a toxic inflammatory reaction that interferes with the patient's recuperation and quality of life. Oral candidiasis is a common fungal infection observed in dental practice, particularly in immunocompromised patients. The aim of this study was to evaluate the presence of oral mucositis and oral candidiasis in patients who underwent HSCT and their correlation with the chemotherapeutic nadir (lowest possible outcome). We evaluated patients with different diagnoses who underwent HSCT at the Hospital Erasto Gaertner. No chemotherapeutic nadir curves could be associated with mucositis, and patients had different presentations of mucositis. No patient developed oral candidiasis during hospitalization. Together with cell counts, we collected demographic data including age, oral hygiene, habits harmful to health, and the use of oral prostheses. It was observed that patients who smoked cigarettes before hospitalization showed less mucositis, resulting in no feeding problems or other comorbid conditions due to the effect of mucositis. However, the nadir of the chemotherapy curve, in isolation, is not a predictive tool for the appearance (or no appearance) of oral mucositis.

    Full Text Available Hematopoietic stem cell transplantation (HSCT still remains the only definitive cure currently available for patients with thalassemia and sickle cell anemia.  Results of transplant in thalassemia  and in sickle cell anemia  have steadily improved over the last two decades due to improvements in preventive strategies, and effective control of transplant-related complications. From 2004 through  2009,  145 consecutive patients with thalassemia and sickle cell anemia, ethnically heterogeneous from Mediterranean and Middle East countries, were given HSCT in the International Center for Transplantation in Thalassemia and Sickle Cella Anemia in Rome. This experience is characterized by two peculiarities: patients were ethnically very heterogeneous and the vast majority of these patients were not regularly transfesed/chelated and therefore were highly sensitized due to RBC transfusions without leukodepletion filters. Consequently, they could have a high risk of graft rejection as a result of sensitization to HLA antigens. The Rome experience of SCT in patients with thalassemia and sickle cell anemia confirmed the results obtained in Pesaro, and most importantly showed the reproducibility of these results in other centers.

    Immune reconstitution plays a crucial role on the outcome of patients given T cell-depleted HLA-haploidentical hematopoietic stem cell transplantation (hHSCT) for hematological malignancies. CD1d-restricted invariant NKT (iNKT) cells are innate-like, lipid-reactive T lymphocytes controlling infections, cancer, and autoimmunity. Adult mature iNKT cells are divided in two functionally distinct CD4(+) and CD4(-) subsets that express the NK receptor CD161 and derive from thymic CD4(+)CD161(-) precursors. We investigated iNKT cell reconstitution dynamics in 33 pediatric patients given hHSCT for hematological malignancies, with a follow-up reaching 6 y posttransplantation, and correlated their emergence with disease relapse. iNKT cells fully reconstitute and rapidly convert into IFN-γ-expressing effectors in the 25 patients maintaining remission. CD4(+) cells emerge earlier than the CD4(-) ones, both displaying CD161(-) immature phenotypes. CD4(-) cells expand more slowly than CD4(+) cells, though they mature with significantly faster kinetics, reaching full maturation by 18 mo post-hHSCT. Between 4 and 6 y post-hHSCT, mature CD4(-) iNKT cells undergo a substantial expansion burst, resulting in a CD4(+)HLA-haploidentical patients failing to reconstitute these cells might represent a novel therapeutic option to prevent leukemia recurrence.

    Purpose: To update the results of a clinical trial that assessed whether the angiotensin-converting enzyme inhibitor captopril was effective in mitigating chronic renal failure and pulmonary-related mortality in subjects undergoing total body irradiation (TBI) in preparation for hematopoietic stem cell transplantation (HSCT). Methods and Materials: Updated records of the 55 subjects who were enrolled in this randomized controlled trial were analyzed. Twenty-eight patients received captopril, and 27 patients received placebo. Definitions of TBI-HSCT-related chronic renal failure (and relapse) were the same as those in the 2007 analysis. Pulmonary-related mortality was based on clinical or autopsy findings of pulmonary failure or infection as the primary cause of death. Follow-up data for overall and pulmonary-related mortality were supplemented by use of the National Death Index. Results: The risk of TBI-HSCT-related chronic renal failure was lower in the captopril group (11% at 4 years) than in the placebo group (17% at 4 years), but this was not statistically significant (p > 0.2). Analysis of mortality was greatly extended by use of the National Death Index, and no patients were lost to follow-up for reasons other than death prior to 67 months. Patient survival was higher in the captopril group than in the placebo group, but this was not statistically significant (p > 0.2). The improvement in survival was influenced more by a decrease in pulmonary mortality (11% risk at 4 years in the captopril group vs. 26% in the placebo group, p = 0.15) than by a decrease in chronic renal failure. There was no adverse effect on relapse risk (p = 0.4). Conclusions: Captopril therapy produces no detectable adverse effects when given after TBI. Captopril therapy reduces overall and pulmonary-related mortality after radiation-based HSCT, and there is a trend toward mitigation of chronic renal failure.

    Most studies on hematopoietic stem cell transplantation (HSCT) have focused on patients, survivors, or their family members, such as siblings and parents. Little attention has been paid to nurses caring for HSCT pediatric patients and in particular in a Taiwanese context. The objective of this study was to explore nurses' lived experience caring for HSCT children in isolation within a general pediatric ward. A Husserlian phenomenological approach informed the exploration of the meaning and essence of the nurses' caring experience. Data were collected using semistructured interviews. Twelve nurses were interviewed. Analysis of interviews yielded 3 main themes: being worried about ruining transplantation success, feeling loss of control in handling suffering, and reflecting upon the value of HSCT. Nurses felt the stress of caring for HSCT children because of the heavy workload and the pressure of responsibility. Witnessing the suffering of patients/families was particularly stressful. However, nurses were helped to overcome this stress by looking at the value and meaning of HSCT. Nurses need practical support from nursing leaders in terms of carefully organizing patient care, controlling the nurse-to-patient ratio, and offering a safe work environment by providing systematic formal training on HSCT and receiving proper supervision. Understanding and learning are gained from nurses who are able to seek meaning from HSCT through appreciating every caregiving effort and through valuing how their nursing role contributes to the quality of patients' care.

    Although outcomes of intensive care for patients undergoing hematopoietic stem cell transplantation (HSCT) have improved in the last two decades, the short-term mortality still remains above 50% among allogeneic HSCT patients. Better selection of HSCT patients for intensive care, and consequently reduction of non-beneficial care, may reduce financial costs and alleviate patient suffering. We reviewed the studies on intensive care outcomes of patients undergoing HSCT published since 2000. The risk factors for intensive care unit (ICU) admission identified in this report were primarily patient and transplant related: HSCT type (autologous vs allogeneic), conditioning intensity, HLA mismatch, and graft-versus-host disease (GVHD). At the same time, most of the factors associated with ICU outcomes reported were related to the patients' functional status upon development of critical illness and interventions in ICU. Among the many possible interventions, the initiation of mechanical ventilation was the most consistently reported factor affecting ICU survival. As a consequence, our current ability to assess the benefit or futility of intensive care is limited. Until better ICU or hospital mortality prediction models are available, based on the available evidence, we recommend practitioners to base their ICU admission decisions on: Patient pre-transplant comorbidities, underlying disease status, GVHD diagnosis/grade, and patients' functional status at the time of critical illness.

    Full Text Available Hematopoietic stem cell transplantation (HSCT is usedfor various hematologic malignancies seen in childrenand adults. There may be several complications before,during, and after the HSCT. Just one of them is endocrinologiccomplications, since endocrine system (particularlythe pituitary gland, thyroid gland, adrenal glands, andgonads is highly sensitive against various stress. Chemotherapyand/or total body irradiation used as preparativeregimens and immunosuppressive agents (especiallycorticosteroids used for the graft-versus-host diseasecan cause hormonal disorders. Time elapsed after theHSCT, transplantation type (autologous or allogeneic,preparative regimen choice, age, and gender determinesthe complications. A multidisciplinary management containinga specialist of endocrinology for these patients ispreferred. In this report, we reviewed the endocrinologiccomplications that observed after the HSCT in childrenand adults referring to the recent literatures. J Clin ExpInvest 2012; 3(1: 149-156

    To study the incidence, causes, and outcome of major ocular complications in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). Retrospective, noncomparative, observational clinical study. The study included a total of 620 patients who underwent allogeneic HSCT in the period from 1997 to 2007 at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia. Allogeneic HSCT. Patients with ocular complications were referred to the ophthalmology division for complete ophthalmologic examination, including visual acuity, tonometry, Schirmer test, biomicroscopy, and dilated ophthalmoscopy. Laboratory investigations were performed whenever indicated. The incidence and causes of major ocular complications after allogeneic HSCT were determined. Visual acuity at 1 year after allogeneic HSCT was recorded. Major ocular complications occurred in 80 (13%) of 620 patients who underwent allogeneic HSCT. There were 36 male patients (45%) and 44 female patients (55%) with a mean age of 29 years and an age range of 9 to 65 years. Prophylaxis for graft-versus-host disease (GVHD) consisted of cyclosporine and methotrexate in 69 patients, and cyclosporine, methotrexate and corticosteroids, or mycophenolate mofetil in 11 patients. The most frequently encountered ocular complications were chronic GVHD, dry eye syndrome without GVHD, corneal ulcers, cataract, glaucoma, cytomegalovirus retinitis, fungal endophthalmitis, and acquisition of allergic conjunctivitis from atopic donors. There was no correlation between the pattern of ocular complications and the transplanted stem cell source. Best-corrected visual acuity (BCVA) at 1 year after transplantation was less than 20/200 in 13 patients (16%), less than 20/50 in 17 patients (21%), and better than 20/50 in 50 patients (63%). Ocular complications are common in patients undergoing allogeneic HSCT. Early recognition and prompt treatment are important. The author(s) have no proprietary or commercial

    Full Text Available Abstract Background Stenotrophomonas maltophilia ubiquitously occurs in the hospital environment. This opportunistic pathogen can cause severe infections in immunocompromised hosts such as hematopoietic stem cell transplantation (HSCT recipients. Between February and July 2016, a cluster of four patients on the HSCT unit suffered from S. maltophilia bloodstream infections (BSI. Methods For epidemiological investigation we retrospectively identified the colonization status of patients admitted to the ward during this time period and performed environmental monitoring of shower heads, shower outlets, washbasins and toilets in patient rooms. We tested antibiotic susceptibility of detected S. maltophilia isolates. Environmental and blood culture samples were subjected to whole genome sequence (WGS-based typing. Results Of four patients with S. maltophlilia BSI, three were found to be colonized previously. In addition, retrospective investigations revealed two patients being colonized in anal swab samples but not infected. Environmental monitoring revealed one shower outlet contaminated with S. maltophilia. Antibiotic susceptibility testing of seven S. maltophlia strains resulted in two trimethoprim/sulfamethoxazole resistant and five susceptible isolates, however, not excluding an outbreak scenario. WGS-based typing did not result in any close genotypic relationship among the patients’ isolates. In contrast, one environmental isolate from a shower outlet was closely related to a single patient’s isolate. Conclusion WGS-based typing successfully refuted an outbreak of S. maltophilia on a HSCT ward but uncoverd that sanitary installations can be an actual source of S. maltophilia transmissions.

    The Patient Protection and Affordable Care Act requires that health care insurers cover routine patient costs associated with participating in clinical trials for cancer and other life-threatening diseases. There is a need to better define routine costs within the context of hematopoietic stem cell transplantation (HSCT) clinical trials. This white paper presents guidance on behalf of the American Society for Blood and Marrow Transplantation for defining a standard HSCT episode and delineates components that may be considered as routine patient costs versus research costs. The guidelines will assist investigators, trial sponsors, and transplantation centers in planning for clinical trials that are conducted as a part of the HSCT episode and will inform payers who provide coverage for transplantation.

    Regulatory T cells (Tregs) are critical for self-tolerance. Although adoptive transfer of expanded Tregs limits graft-versus-host disease (GVHD) after hematopoietic stem cell transplantation (HSCT), ex vivo generation of large numbers of functional Tregs remains difficult. Here, we demonstrate that in vivo targeting of the TNF superfamily receptor TNFRSF25 using the TL1A-Ig fusion protein, along with IL-2, resulted in transient but massive Treg expansion in donor mice, which peaked within days and was nontoxic. Tregs increased in multiple compartments, including blood, lymph nodes, spleen, and colon (GVHD target tissue). Tregs did not expand in bone marrow, a critical site for graft-versus-malignancy responses. Adoptive transfer of in vivo-expanded Tregs in the setting of MHC-mismatched or MHC-matched allogeneic HSCT significantly ameliorated GVHD. Critically, transplantation of Treg-expanded donor cells facilitated transplant tolerance without GVHD, with complete sparing of graft-versus-malignancy. This approach may prove valuable as a therapeutic strategy promoting transplantation tolerance. Copyright © 2017 The American Society for Blood and Marrow Transplantation. Published by Elsevier Inc.

    Liver transplantation is intended to increase the survival of patients with chronic liver disease in terminal phase, as well as improved quality of life. Since the first transplant until today many changes have occurred in the organ allocation system. To review the literature on the Model for End-stage Liver Disease (MELD) and analyze its correlation with survival after liver transplantation. An integrative literature review in Lilacs, SciELO, and Pubmed in October 2015, was realized. Were included eight studies related to the MELD score and its impact on liver transplant. There was predominance of transplants in male between 45-55 y. The main indications were hepatitis C, hepatocellular carcinoma and alcoholic cirrhosis. The most important factors post-surgery were related to the MELD score, the recipient age, expanded donor criteria and hemotransfusion. The MELD system reduced the death rate in patients waiting for a liver transplant. However, this score by itself is not a good predictor of survival after liver transplantation. O transplante de fígado tem como finalidade o aumento da sobrevida dos pacientes com doença hepática crônica em fase terminal, além de melhora na qualidade de vida. Desde o primeiro transplante até os dias atuais, muitas mudanças ocorreram no sistema de alocação de órgãos. Analisar o conhecimento produzido sobre o Model for End-stage Liver Disease (MELD) e a sua relação com a sobrevida no pós-transplante de fígado. Realizou-se revisão integrativa nas bases de dados Lilacs, SciELO e Pubmed no mês de outubro de 2015. A amostra contou com oito estudos relacionando o escore MELD e o seu impacto no transplante de fígado. Houve predomínio dos transplantes realizados em homens e faixa etária entre 45-55 anos. Como principais indicações tem-se hepatite C, hepatocarcinoma e cirrose por álcool. Os fatores que tiveram maior impacto no pós-operatório estão associados ao alto valor do MELD, idade do receptor, crit

    The purpose of this study was to evaluate the mid- and long-term results of percutaneous transhepatic cholangiography (PTC) and biliary drainage in children with isolated bilioenteric anastomotic stenosis (BAS) after pediatric liver transplantation. Sixty-four children underwent PTC from March 1993 to May 2008. Nineteen cholangiograms were normal; 10 showed intrahepatic biliary stenosis and BAS, and 35 showed isolated BAS. Cadaveric grafts were used in 19 and living donor grafts in 16 patients. Four patients received a whole liver, and 31 patients received a left lobe or left lateral segment. Roux-en-Y hepaticojejunostomy was performed in all patients. Indication for PTC was based on clinical, laboratory, and histopathologic findings. In patients with isolated BAS, dilation and biliary catheter placement, with changes every 2 months, were performed. Patients were separated into 4 groups according to number of treatment sessions required. The drainage catheter was removed if cholangiogram showed no significant residual stenosis and normal biliary emptying time after a minimum of 6 months. The relationship between risk factors (recipient's weight 20 months, 4 patients (4 of 35; 11.4%) required 1 additional treatment session (group III), and 1 patient (1 of 35; 2.9%) had a catheter placed at the end of the study period (group IV). Drainage time in group I was significantly shorter than those in groups II, III, and IV (p 0.05). The majority of complications, such as catheter displacement and leakage, were classified as minor; however, 2 patients (5.7%) with hemobilia were noted. Complications increased according to the need for reintervention. In conclusion, balloon dilation and percutaneous drainage placement is safe and effective, and it has long-term patency for children with BAS after liver transplantation. Because of prolonged treatment time, reintervention may be necessary, thereby increasing the complication rate. Balloon dilation and percutaneous drainage

    Hematopoietic stem cell transplantation (HSCT) has evolved for >20 years as a specific treatment of patients with autoimmune disease (AD). Using European Society for Blood and Marrow Transplantation registry data, we summarized trends and identified factors influencing activity and outcomes in patients with AD undergoing first autologous HSCT (n = 1951; median age, 37 years [3-76]) and allogeneic HSCT (n = 105; median age, 12 years [<1-62]) in 247 centers in 40 countries from 1994 to 2015. Predominant countries of activity were Italy, Germany, Sweden, the United Kingdom, The Netherlands, Spain, France, and Australia. National activity correlated with the Human Development Index ( P = .006). For autologous HSCT, outcomes varied significantly between diseases. There was chronological improvement in progression-free survival (PFS, P < 10 -5 ), relapse/progression ( P < 10 -5 ), and nonrelapse mortality ( P = .01). Health care expenditure was associated with improved outcomes in systemic sclerosis and multiple sclerosis (MS). On multivariate analysis selecting adults for MS, systemic sclerosis, and Crohn disease, better PFS was associated with experience (≥23 transplants for AD, P = .001), learning (time from first HSCT for AD ≥6 years, P = .01), and Joint Accreditation Committee of the International Society for Cellular Therapy and European Society for Blood and Marrow Transplantation accreditation status ( P = .02). Despite improved survival over time ( P = .02), allogeneic HSCT use remained low and largely restricted to pediatric practice. Autologous HSCT has evolved into a treatment modality to be considered alongside other modern therapies in severe AD. Center experience, accreditation, interspecialty networking, and national socioeconomic factors are relevant for health service delivery of HSCT in AD.

    Multiple sclerosis (MS) is thought to be an autoimmune disease targeting the central nervous system leading to demyelination, and axonal and neuronal damage, resulting in progressive disability. More intensive therapies such as immunodepletion with hematopoietic stem-cell rescue are being used at a time prior to patients becoming irreversibly disabled. Over the last 15 years, there has been a shift away from using autologous hematopoietic stem-cell transplants (aHSCT) to treat patients with progressive MS, towards treating those with active inflammation and relapses. There is an increasing body of evidence that aHSCT improves all measured MS outcomes, including burden of disease on MRI, clinical relapses, accumulation of disability, and quality of life of patients with active MS not controlled with standard therapy. Importantly, the progression-free survival curves of these patients plateau after the first few years demonstrating the impact that aHSCT has in changing the natural history of MS, potentially freeing patients from the relentless accumulation of disability. Concurrently there has been a reduction in procedure-related mortality. The results of randomized trials will likely spur further development of this field.

    Allogeneic stem cell transplantation (SCT) is the treatment of choice for young patients (age ≤ 55 years) with myelodysplastic syndromes (MDS) characterized by poor-risk or intermediate-risk cytogenetics, who have a histocompatible related or unrelated donor. For patients who lack an human leukocyte antigen-compatible donor, autologous SCT, or chemotherapy may be good alternatives for those with MDS and with good-risk cytogenetic characteristics. Iron toxicity is an underestimated cause of hematopoietic stem cell transplantation (HSCT) treatment-related mortality. The pathogenesis, diagnosis, and monitoring of iron-induced organ damage are currently topics of investigation. Prospective studies on the prevention or treatment of iron toxicity before HSCT and/or after HSCT are necessary. Copyright © 2011. Published by Elsevier Inc.

    The timely reconstitution and regain of function of a donor-derived immune system is of utmost importance for the recovery and long-term survival of patients after allogeneic hematopoietic stem cell transplantation (HSCT). Of note, new developments such as umbilical cord blood or haploidentical grafts were associated with prolonged immunodeficiency due to delayed immune reconstitution, raising the need for better understanding and enhancing the process of immune reconstitution and finding strategies to further optimize these transplant procedures. Immune reconstitution post-HSCT occurs in several phases, innate immunity being the first to regain function. The slow T cell reconstitution is regarded as primarily responsible for deleterious infections with latent viruses or fungi, occurrence of graft-versus-host disease, and relapse. Here we aim to summarize the major steps of the adaptive immune reconstitution and will discuss the importance of immune balance in patients after HSCT. PMID:27909435

    STAT4 polymorphism, rs7574865 is linked to various autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. Its T minor allele is associated with higher STAT4 mRNA and protein expression, indicating a stronger skewed immune response than the norm. Although widely studied in autoimmune disease patients and the general population, its effect on immunocompromised subjects is still unknown. Especially in situations, i.e. post-hematopoietic stem cell transplantation (post-HSCT), where control of the immune response is crucial. Hence, this study investigates if the presence of the T minor allele in donors would affect immunological response and clinical outcomes post-HSCT. Samples from 161 pediatric patients who underwent allogeneic HSCT for acute leukemia and showed complete chimerism by donor cells were obtained. Six clinical outcomes were investigated; hepatic veno-occlusive disease, acute graft-vs-host disease, chronic graft-vs-host disease, cytomegalovirus (CMV) infection, relapse and overall survival. The TT genotype was found to be significant in the occurrence of CMV infection (P=0.049), showing higher incidence of CMV infection compared to the others. Multivariate analysis confirmed that association of the TT genotype is independent from other variables in CMV infection occurrence (P=0.010). This is the first study on STAT4 polymorphism rs7574865 in allogeneic HSCT as well as immunocompromised patients. As the TT genotype is associated with autoimmune diseases, our results seem at a paradox with current evidence hinting at a different role of STAT4 in normal circumstances versus immunocompromised patients. Further investigation is needed to elicit the reason behind this and discover novel applications for better post-transplant outcomes. Copyright © 2016 Elsevier B.V. All rights reserved.

    A previous study reported a 45% incidence of falling among allogeneic haematopoietic stem cell transplantation (allo-HSCT) patients during hospitalisation. We investigated balance and physical function in allo-HSCT patients. Thirty patients (18 men and 12 women) who underwent allo-HSCT between February 2013 and September 2014 were included in this study. Patients were evaluated for up to 3 weeks before and 7 weeks after transplantation. Balance was evaluated using the Timed Up and Go test (TUG) and length of centre of pressure (CoP). Physical function was assessed using hand-grip strength, knee-extensor strength tests, and the 6 min walk test (6MWT). TUG and length of CoP were significantly increased following HSCT (PCoP were negatively correlated with hand grip and knee-extensor strength (P≤0.05). The allo-HSCT patients in this study had worsened dynamic and static movements of the CoP after transplantation as well as decline of physical function. Rehabilitation staff, nurses, and physicians should recognize the decreased balance function of patients who have undergone allo-HSCT. Copyright © 2015 Elsevier B.V. All rights reserved.

    To determine the current state of kidney transplantation (KT) training in a country that is leader in organ donation and transplantation. We conducted an online survey by e-mail to 138 urology residents. The survey contained 5 sections: affiliation, training in KT, interest in KT, residents of transplant centers and residents of nontransplant centers. Sixty-five residents responded, 47.1% of the urologists in training surveyed, representing 28 cities and 15 provinces. Fifty-five percent (n=36) of the respondents deemed the KT training offered during their residency as insufficient, and 85% (n=55) demanded more resources. More than half were not confident in their abilities to perform transplantation surgery over the course of their residency (n=35). Nineteen percent of the residents considered KT an important discipline in their residency, with a mean score of 56.2 (1-100). Among the residents of the transplant centers (69.2%, n=45), 73% (n=33) considered KT when choosing a center for their residency. Of the surveyed residents from nontransplant centers (30.7%, n=20), 45% (n=9) do not perform an external rotation in KT. The surveyed residents demand more training in KT. The most common situation is to end a residency without having performed a complete KT. KT is considered an asset when selecting a resident medical intern position and commonly they are part of the transplantation team. The majority of residents are trained in centers with less than 75 transplants/year. External rotations in KT are not the rule in centers where transplantation is not performed. Copyright © 2014 AEU.

    Full Text Available Abstract: Infections with Hepatitis viruses B and C pose major problems both short and long term respectively after HSCT. The key to prevention for Hepatitis B disease remains vaccination for HBV-naïve patients and judicial use of anti-viral therapy in both pre- and post-transplant settings for HBV-infected patients. HBsAg positive grafts to HBV-naïve recipients result in transmission of the virus in about 50%. The newer anti-viral agents have enabled effective treatment of post-transplant patients who might be lamivudine-resistant or might develop so. Selecting a previously infected donor who has high titres of surface antibody for HBsAg positive patients gives the best chance for immunological clearance. The most challenging aspect of preventing HBV reactivation remains the duration of anti-viral therapy and timing of its withdrawal as most reactivations and often fatal ones occur after this period. Hepatitis C, on the other hand affects long-term survival with early onset of fibrosis and cirrhosis. Early effect of Hepatitis C virus on the immune system remains conjectural. The standard combination therapy seems to be effective, but data on this front remains sparse, as in the case of the use of newer antiviral agents. HSCT from HCV infected grafts result in more consistent transmission of the virus and pre-donation treatment of donors should be undertaken to render them non-viremic, if possible.  The current understanding and recommendations regarding prevention and management of these infections in HSCT recipients are discussed.

    Full Text Available Abstract Background Haploidentical donor (HID hematopoietic stem cell transplantation (HSCT is an alternative treatment method for severe aplastic anemia (SAA patients lacking suitable identical donors and those who are refractory to immunosuppressive therapy (IST. The current study evaluated the feasibility of upfront haploidentical HSCT in SAA patients. Methods We conducted a multicenter study based on a registry database. One hundred fifty-eight SAA patients who underwent upfront transplantation between June 2012 and September 2015 were enrolled. Results Eighty-nine patients had haploidentical donors (HIDs, and 69 had matched related donors (MRDs for HSCT. The median times for myeloid engraftment in the HID and MRD cohorts were 12 (range, 9–20 and 11 (range, 8–19 days, with a cumulative incidence of 97.8 and 97.1% (P = 0.528, respectively. HID recipients had an increased cumulative incidence of grades II–IV acute graft-versus-host disease (aGVHD (30.3 vs. 1.5%, P < 0.001, grades III–IV aGVHD (10.1 vs. 1.5%, P = 0.026, and chronic GVHD (cGVHD (30.6 vs. 4.4%, P < 0.001 at 1 year but similar extensive cGVHD (3.4 vs. 0%, P = 0.426. The three-year estimated overall survival (OS rates were 86.1 and 91.3% (P = 0.358, while the three-year estimated failure-free survival (FFS rates were 85.0 and 89.8% (P = 0.413 in the HID and MRD cohorts, respectively. In multivariate analysis, survival outcome for the entire population was significantly adversely associated with increased transfusions and poor performance status pre-SCT. We did not observe differences in primary engraftment and survival outcomes by donor type. Conclusions Haploidentical SCT as upfront therapy was an effective and safe option for SAA patients, with favorable outcomes in experienced centers.

    Full Text Available Objectives: To investigate the long-term efficacy and results of surgical management of conjunctival melanoma reconstructed with amniotic membrane transplantation. Materials and Methods: Conjunctival melanoma in 10 patients (5 female, 5 male was totally excised with adjunctive cryotherapy to the surgical margins, corneal epitheliectomy with absolute alcohol in cases of corneal involvement, lamellar sclerectomy in cases with episcleral involvement, and ocular surface grafting with cryopreserved amniotic membrane. Complications and tumor control rates were evaluated. Results: The mean age of the patients was 57.4±15.2 (range, 37-84 years. The mean diameter of the tumors was 15.5±4.9 (range, 10-25 mm and histopathologically confirmed complete excision was performed in all cases. Mild limbal stem cell deficiency (2 eyes and subclinical symblepharon (3 eyes were observed as long-term complications. In a mean follow-up of 56.7±40.4 (range, 30-132 months, only one local tumor recurrence was detected. Despite retreatment, exenteration was performed in this patient due to re-recurrence. One patient died due to disseminated metastasis despite the absence of local recurrence. Conclusion: In large conjunctival melanomas, reconstruction of the ocular surface is usually very challenging. The use of cryopreserved amniotic membrane for conjunctival defect repair is safe and effective with mild complications, and allows the excision of wider margins around the tumor.

    Patients with primary refractory Hodgkin's disease (PR-HD) have a dismal prognosis when treated with conventional salvage chemotherapy. We analyzed time to treatment failure (TTF), overall survival (OS) and clinical variables influencing the outcome in patients undergoing autologous stem cell transplantation (ASCT) for PR-HD and reported to the Grupo Español de Linfomas/Trasplante Autólogo de Médula Osea (GEL/TAMO). Sixty-two patients, 41 males and 21 females with a median age of 27 years (range 13-55) were analyzed. Forty-two patients (68%) had advanced stage at diagnosis, 47 (76%) presented with B symptoms and 29 (47%) with a bulky mediastinal mass. Seventy-five percent of the patients had received more than one line of therapy before ASCT. Thirty-three patients received bone marrow as a source of hematopoietic progenitors, and 29 peripheral blood. Six patients were conditioned with high-dose chemotherapy plus total-body irradiation and 56 received chemotherapy-based protocols. One-year transplantation-related mortality was 14% [95% confidence interval (CI) 6% to 23%]. Response rate at 3 months after ASCT was 52% [complete remission in 21 patients (34%), partial remission in 11 patients (18%)]. Actuarial 5-year TTF and OS were 15% (95% CI 5% to 24%) and 26% (95% CI 13% to 39%), respectively. The presence of B symptoms at ASCT was the only adverse prognostic factor significantly influencing TTF [relative risk (RR) 1.75, 95% CI 0.92-3.35, P = 0.08]. The presence of B symptoms at diagnosis (RR 2.08, 95% CI 0.90-4.79, P = 0.08), MOPP-like regimens as first-line therapy (RR 3.84, 95% CI 1.69-9.09, P = 0.001), bulky disease at ASCT (RR 2.79, 95% CI 0.29-6.03, P = 0.009) and two or more lines of therapy before ASCT (RR 2.24, 95% CI 0.95-5.27, P = 0.06) adversely influenced OS. In our experience, although overall results of ASCT in PR-HD patients are poor, one-quarter of the patients remain alive at 5 years. Despite this, other therapeutic strategies should be

    Medication adherence is essential in kidney transplant recipients to reduce the risk of rejection and subsequent allograft loss. The aim of this study was to delineate what 'usual care' entails, in relation to medication management, for adult kidney transplant recipients. An online survey was developed to explore how nephrologists promote and assess medication adherence, the management of prescriptions, the frequency of clinic appointments and the frequency of clinical screening tests. Nephrologists from all acute kidney transplant units in Victoria, Australia, were invited to participate. Data were collected between May and June 2014. Of 60 nephrologists invited to participate, 22 completed the survey (response rate of 36.6%). Respondents had a mean age of 49.1 ± 10.1 years, with a mean of 20.1 ± 9.9 years working in nephrology and 14 were men. Descriptive analysis of responses showed that nephrologists performed frequent screening for kidney graft dysfunction that may indicate medication non-adherence, maintained regular transplant clinic visits with patients and emphasized the importance of medication education. However, time constraints during consultations impacted on extensive patient education and the long-term medication follow-up support was often delivered by the renal transplant nurse coordinator or pharmacist. This study highlighted that nephrologists took an active approach in the medication management of kidney transplant recipients, which may assist with facilitating long-term graft survival. Ultimately, promoting medication adherence needs to be patient centred, involving an interdisciplinary team of nephrologists, pharmacists and renal transplant nurse coordinators, working together with the patient to establish optimal adherence. © 2015 John Wiley & Sons, Ltd.

    Background: Pulmonary aspergillosis (PA) is one of the most serious complications in immunocompromised patients, in particular among hematopoietic stem cell transplants (HSCT) and patients with hematological malignancies. Objectives: The current study aimed to evaluate the incidence of PA and utility of molecular methods in HSCT and patients with hematological malignancies, four methods including direct examination, culture, nested polymerase chain reaction (PCR) and real-time PCR were performed on bronchoalveolar lavage (BAL) specimens in Tehran, Iran. Patients and Methods: During 16 months, 46 BAL specimens were obtained from individuals with allogeneic HSCT (n = 18) and patients with hematological malignancies (n = 28). Direct wet mounts with 20% potassium hydroxide (KOH) and culture on mycological media were performed. The molecular detection of Aspergillus fumigatus and A. flavus was done by amplifying the conserved sequences of internal transcribed spacer 1 (ITS1) ribosomal DNA by nested-PCR and the β-tubulin gene by TaqMan real-time PCR. Results: Seven (15.2%) out of 46 specimens were positive in direct examination and showed branched septate hyphae; 11 (23.9%) had positive culture including eight (72.7%) A. flavus and three (27.3%) A. fumigatus; 22 (47.8%) had positive nested-PCR and eight (17.4%) had positive real-time PCR. The incidence of invasive pulmonary aspergillosis (IPA) in these patients included proven IPA in 1 (2.2%), probable IPA in 10 (21.7%), possible IPA in 19 (41.3%) and not IPA in 16 cases (34.8%). Conclusions: The incidence of IPA in allogeneic HSCT and patients with hematological malignancies was relatively high and A. flavus was the most common cause of PA. As molecular methods had higher sensitivity, it may be useful as screening methods in HSCT and patients with hematological malignancies, or to determine when empirical antifungal therapy can be withheld.

    Objectives. This study examines the short- and long-term QOL benefits of a music therapy intervention for patients recovering from hematopoietic stem cell transplantation (HSCT). Methods. Ninety allogeneic HSCT patients, after transplant, were randomized to receive ISO-principle (i.e., mood matching) based music therapy (MT; n = 29), unstructured music (UM; n = 30), or usual care (UC; n = 31) for four weeks. The ISO principle posits that patients may shift their mood from one state to another by listening to music that is "equal to" the individual's initial mood state and subsequently listening to music selections that gradually shift in tempo and mood to match the patient's desired disposition. Participants in MT and UM groups developed two audio CDs to help them feel more relaxed and energized and were instructed to use the CDs to improve their mood as needed. Short-term effects on mood and long-term effects on QOL were examined. Results. MT and UM participants reported improved mood immediately after listening to CDs; the within-group effect was greater for UM participants compared to MT participants. Participant group was not associated with long-term QOL outcomes. Conclusions. Music listening improves mood acutely but was not associated with long-term benefits in this study.

    Full Text Available Hematopoietic stem cell transplantation (HSCT is the most potent curative therapy for many malignant and non-malignant disorders. Unfortunately, a major complication of HSCT is graft-versus-host disease (GVHD, which is mediated by tissue damage resulting from the conditioning regimens before the transplantation and the alloreaction of dual immune components (activated donor T cells and recipient’s antigen-presenting cells. This tissue damage leads to the release of alarmins and the triggering of pathogen-recognition receptors that activate the innate immune system and subsequently the adaptive immune system. Alarmins, which are of endogenous origin, together with the exogenous pathogen-associated molecular patterns (PAMPs elicit similar responses of danger signals and represent the group of damage-associated molecular patterns (DAMPs. Effector cells of innate and adaptive immunity that are activated by PAMPs or alarmins can secrete other alarmins and amplify the immune responses. These complex interactions and loops between alarmins and PAMPs are particularly potent at inducing and then aggravating the GVHD reaction. In this review, we highlight the role of these tissue damaging molecules and their signaling pathways. Interestingly, some DAMPs and PAMPs are organ specific and GVHD-induced and have been shown to be interesting biomarkers. Some of these molecules even represent potential targets for novel therapeutic approaches.

    Receptors on natural killer (NK) cells, named killer immunoglobulin-like receptors (KIRs), recognize HLA class I alleles. Patients (n=59) who received allogeneic hematopoietic stem cell transplantation (HSCT) from either a related (n=17) or unrelated donor (n=42) in Samsung Medical Center (Seoul, South Korea) were included. KIR mismatch was defined as incompatibility between the donor KIR and recipient KIR ligand (receptor-ligand model), and all cases were classified into the two broad haplotypes of KIR A and B. Patients with acute leukemia (n=51, 86.4%) or myelodysplastic syndrome (n=8, 13.6%) were included. Peripheral blood was used as the source of stem cells in all patients. Kaplan-Meier survival curves for overall survival (OS), disease-free survival (DFS), and cumulative incidence of relapse (CIR) favored recipients with a KIR-mismatched donor, although the differences were not statistically significant. In multivariate analysis, KIR mismatch was an independent prognostic indicator of a better OS (P=0.010, HR=0.148, 95% CI 0.034-0.639), DFS (P=0.022, HR=0.237, 95% CI 0.069-0.815), and CIR (P=0.031, HR=0.117, 95% CI 0.017-0.823). OS, DFS, and CIR did not differ significantly between the KIR A and B haplotypes. Copyright © 2015. Published by Elsevier Inc.

    Allograft lithiasis is a rare urologic complication of renal transplantation (RT). Our aim is to present our experience with minimally invasive surgical treatment of allograft lithiasis in our series of live-donor renal transplant recipients. In a retrospective analysis of 3758 consecutive live-donor RTs performed in our center between November 2009 and January 2017, the results of minimally invasive surgery for the treatment of renal graft lithiasis diagnosed at follow-up were evaluated. Twenty-two (0.58%) patients underwent minimally invasive surgery for renal graft lithiasis. The mean age was 41.6 years, and duration between RT and surgical intervention was 27.3 months (range 3-67). The mean stone size was 11.6 mm (range 4-29). Stones were located in the urethra in 1, bladder in 2, ureter in 9, renal pelvis in 7 and calices in 3 patients. Surgical treatment included percutaneous nephrolithotomy in 1, cystoscopic lithotripsy in 3, flexible ureteroscopic lithotripsy in 6 and rigid ureteroscopic lithotripsy in 12 patients. No major complications were observed. One patient (4.5%) who underwent flexible ureteroscopy developed postoperative urinary tract infection. All patients were stone-free except two (9%) patients who required a second-look procedure after flexible ureteroscopic lithotripsy for residual stones. Stone recurrence was not observed in any patient during a mean follow-up duration of 30.2 months (range 8-84). Renal transplant lithiasis is uncommon and minimally invasive surgical treatment is rarely performed for its treatment. Endourological surgery may be performed safely, effectively and with a high success rate in these patients.

    [corrected] Hepatocellular carcinoma is the most frequent malignant hepatic tumor in humans, and its association with cirrhosis makes the therapeutic approach still a challenge. Liver transplantation is the treatment of choice for cirrhotic patients with unresectable early hepatocellular carcinoma To evaluate the post-transplant outcome of a cohort of 15 cirrhotic patients with preoperative diagnosis of unresectable early hepatocellular carcinoma according the Milan criteria who underwent liver transplantation between September 1991 and December 2003 We retrospectively reviewed the clinical data from 15 liver transplant recipients and the explanted livers were assessed for the efficacy of preoperative therapy. Patient survival and tumor recurrence were evaluated as primary outcome measures The mean age of the patients was 49.2 +/- 14.3 years and hepatitis C was the etiology of the underlying liver disease in 60%. Preoperative therapy, either chemoembolization or percutaneous ethanol injection, was performed in 12 (86%) patients. Complete necrosis of all tumoral lesions were observed in 5 of 12 patients (44,66%); all others had variable amounts of viable tumor in the explanted liver. Only 4 of the 15 (26.6%) explanted livers had microscopic vascular invasion. The median post-transplant follow-up was 33 months (range: 8-71 months) and no tumor recurrence was detected during this period. The only death was an early event not related to the tumor. The recurrence-free survival rates at 1 and 3 years were 93% Liver transplantation has emerged as a good alternative for cirrhotic patients with early hepatocellular carcinoma not amenable to curative resection, offering excellent recurrence-free survival rates.

    Early immune reconstitution plays a critical role in clinical outcome after allogeneic hematopoietic stem cell transplantation (HSCT). Natural killer (NK) cells are the first lymphocytes to recover after transplantation and are considered powerful effector cells in HSCT. We aimed to evaluate...... the clinical impact of early NK cell recovery in T-cell replete transplant recipients. Immune reconstitution was studied in 298 adult patients undergoing HSCT for acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL) and myelodysplastic syndrome (MDS) from 2005 to 2013. In multivariate analysis NK...... cell numbers day 30 (NK30) >150cells/µL were independently associated with superior overall survival (hazard ratio 0.79, 95% confidence interval 0.66-0.95, p=0.01).

    Full Text Available Abstract Background Adiponectin is a major adipocyte-derived protein with insulin-sensitizing, anti-inflammatory and anti-atherogenic properties. Adiponectin levels correlate inversely with renal function and higher levels are predictive of lower cardiovascular disease (CVD in patients with normal renal function and chronic kidney disease. No data exists on the association between adiponectin and CVD in renal transplant recipients (RTR. Methods Standard biochemistry, clinical data and adiponectin were collected from 137 RTR recruited to the LANDMARK 2 study at baseline. The LANDMARK 2 study is an ongoing randomized controlled study that compares the outcome of aggressive risk factor modification for cardiovascular disease versus standard post-transplant care in renal transplant recipients with impaired glucose tolerance or diabetes mellitus. Results Mean patient age was 53.4 ± 12 years and the median post-transplantation period was 5 (0.5-31.9 years. Mean serum adiponectin level was 12.3 ± 7.1 μg/mL. On univariate analysis, adiponectin was positively associated with female gender (P = 0.01 and serum high-density lipoprotein (HDL concentration (P Conclusion In conclusion, adiponectin is positively correlated with inflammation, dyslipidemia and abnormal glucose tolerance in RTR. Furthermore, hypoadiponectinemia correlated with increased baseline CVD in male RTR.

    The incidence and risk factors for acute cholecystitis after allogeneic hematopoietic stem cell transplantation (HSCT) are not well defined. Of 644 consecutive adult transplants performed at our institution between 2001 and 2011, acute cholecystitis occurred in the first year of transplant in 32 patients (5.0%). We conducted 2 retrospective case-control studies of this population to determine risk factors for cholecystitis after HSCT and to evaluate the performance of different methods of imaging to diagnosis cholecystitis in patients undergoing HSCT compared with non-HSCT patients. In the HSCT population, development of cholecystitis was associated with an increased 1-year overall mortality rate (62.5% versus 19.8%, P cholecystitis was higher in patients who received total parenteral nutrition (TPN) (adjusted odds ratio, 3.41; P = .009). There was a trend toward more equivocal abdominal ultrasound findings in HSCT recipients with acute cholecystitis compared with nontransplant patients (50.0% versus 30.6%, P = .06). However, hepatobiliary iminodiacetic acid (HIDA) scans were definitively positive for acute cholecystitis in most patients in both populations (80.0% of HSCT recipients versus 77.4% of control subjects, P = .82). In conclusion, acute cholecystitis is a common early complication of HSCT, the risk is increased in patients who receive TPN, and it is associated with high 1-year mortality. In HSCT recipients with findings suggestive of acute cholecystitis, especially those receiving TPN, early use of HIDA scan may be considered over ultrasound.

    Hemophagocytic lymphohistiocytosis (HLH) is an immune regulatory disorder that commonly presents with central nervous system (CNS) involvement. The only cure for genetic HLH is hematopoietic stem cell transplantation (HSCT), typically treated with reduced-intensity conditioning (RIC) regimens. We sought to estimate the incidence of CNS relapse after RIC HSCT, determine risk factors, and evaluate outcomes. We performed a retrospective chart review of 94 consecutive children and young adults with primary HLH who received RIC HSCT. CNS relapse within 1 year after transplantation was diagnosed by review of clinical symptoms, cerebral spinal fluid (CSF), and radiologic findings. Four (4.25%) patients developed symptoms of possible CNS HLH after HSCT and 3 patients were diagnosed. Eight patients underwent screening lumbar puncture because of history of active CNS disease at the onset of the conditioning regimen and 4 had evidence of continued disease. The overall incidence of CNS relapse and continued CNS disease after RIC HSCT was 8%. All patients with CNS disease after HSCT responded to CNS-directed therapy. Whole blood donor chimerism at the time of CNS relapse was low at 1% to 34%, but it remained high at 88% to 100% for patients with continued CNS disease. Overall survival for patients with CNS relapse was 50%, compared with 75% for patients without CNS disease (P = .079). Our data suggest that a low level of donor chimerism or active CNS disease at the time of transplantation increase the risk of CNS HLH after HSCT. Surveillance CSF evaluation after allogeneic RIC HSCT should be considered in patients with risk factors and CNS-directed treatment should be initiated if appropriate.

    Immune hemolytic anemia is a well-known complication after allogeneic hematopoietic stem cell transplantation (HSCT). Posttransplant hemolytic anemia results in increased red blood cell transfusions and medical sequelae including iron overload. We present a case report of immune hemolytic anemia that occurred after allogeneic HSCT from an ABO major-mismatched, HLA-matched unrelated donor. The patient had high anti-donor A type antibodies that were unresponsive to treatment with steroids and rituximab, resulting in persistent transfusion dependence. A detailed time course of anti-A titers, plasma cell content of the marrow, and B-cell content of the blood is presented. Treatment with bortezomib, a protease inhibitor, eliminated residual host-type plasma cells secreting anti-A and restored normal donor-derived erythropoiesis. This report, and a review of literature for treatment of immune hemolytic anemia after allogeneic HSCT, supports the utility of bortezomib as plasma cell-targeted therapy in this setting. © 2014 The Authors.

    Management of posttransplantation malignancies should include control of the neoplasia and preservation of renal function. Conversion to everolimus (EVL) would potentially have both effects. Twenty-one patients were converted to EVL due to posttransplantation neoplasms. We have presented herein descriptive data and postconversion (PC) outcomes among subjects of mean age 53.6 +/- 10.1 years (range, 36-69), 57.1% were males, undergoing conversion at 108.2 +/- 74.7 (range, 5-316) months after transplantation. All patients received standard immunosuppressive therapy and 9.5% had been induced with thymoglobulin. Malignant neoplasms were as follows: skin (n = 7), gynecological (n = 3), gastrointestinal (n = 3), PTLD (n = 2), renal (n = 2), CNS (n = 1), seminoma (n = 1), Kaposi's sarcoma (n = 1), and prostate cancer (n = 1). PC to EVL, calcineurin inhibitors (CNIs) were discontinued in 18 of 19 patients, mycophenolate in 9/12, and azathioprine in 5/7; all patients continued to receive steroids. In 16 patients (79%) tumors were removed. Chemotherapy was performed in 2 patients with PTLD and radiotherapy was performed in 1 patient with prostate cancer. Mean follow-up was 505 days (range, 59-1151); baseline glomerular filtration rate (GFR) was 53.5 +/- 21.6 mL/min versus 48.5 +/- 25.7 mL/min (P = not significant [NS]) at the last control. One patient experienced graft loss at day 744 after conversion due to chronic rejection. Adverse events were observed in 57% of patients and 28% displayed infections; no patient discontinued EVL. There were 2 deaths: 1 due to an infection and the other due to postsurgical complication. No deaths due to cancer progression were observed. The results observed in this series suggested that conversion to EVL for a posttransplantation neoplasm is a valid therapeutic alternative to preserve graft function and control disease progression.

    To review the results of 137 living donor pediatric liver transplants performed at Riyadh Military Hospital (RMH). Retrospective analysis of the in- and out-patient case notes was carried out. Data were collected regarding age, gender, nationality, diagnosis, type of procedure, complications and survival of the grafts and the recipients. The first 137 living donor pediatric liver transplants were performed in 113 months. The age range was 4.5 months to 14 years. Eighty-four recipients (61%) were male. One hundred and twelve children were Saudi. Left lateral segment was used as allograft in 135 cases. One child each received full left lobe and full right lobe. Six auxiliary partial orthotopic liver transplants were carried out. Familial metabolic liver disorders made the largest group of children needing transplant. The most common indications were progressive familial intrahepatic cholestasis and biliary atresia (45 cases each). The numbers of major complications are: hepatic artery thrombosis (n=8); portal vein thrombosis (n=3); portal vein stenosis (n=3); hepatic vein stenosis (n=3) and biliary strictures (n=4). Fifteen patients died. Three further allografts have been lost. Thus, the overall patient survival rate is 89% and graft survival rate is 86.8%. Living donor liver transplantation is a viable option for children with end-stage liver disease. Metabolic liver disease is the most common indication in Saudi Arabia. The cadaveric donor supply is in shortage and living donation is a practical alternative. The incidence of complications and recipient and graft survival rates of the program at RMH are acceptable, (author)

    Emerging evidence from graft manipulations and immunotherapeutic treatments has highlighted a favorable effect of γδ T cells in the setting of allogeneic hematopoietic stem cell transplantation (alloHSCT). However, γδ T cell subsets and their distinct features in the allograft have not been characterized. Additionally, whether homeostatic γδ T cell fractions are influenced by treatment with granulocyte colony-stimulating factor (G-CSF) remains elusive. We initially compared the phenotypes of γδ T cell subsets, including CD27 + , CD27 - , Vδ1 + , Vδ2 + , Vδ1 + CD27 + , Vδ1 + CD27 - , Vδ2 + CD27 + , and Vδ2 + CD27 - cells, in the peripheral blood of 20 healthy donors before and after G-CSF mobilization. The effects of G-CSF on the cytokine production capacities of γδ T cell subsets were also detected. Moreover, the correlation between donor homeostatic γδ T cell content and the early recoveries of γδ T cell subgroups after haploidentical HSCT was investigated in 40 pairs of donors and recipients. We found that both the proportions and IFN-γ secretion capacities of peripheral γδ T cell subsets were preserved in G-CSF-primed grafts. Homeostatic Vδ1 and Vδ2 proportions of donors significantly correlated with the early recoveries of Vδ1 and Vδ2 cells after haploidentical HSCT. Interestingly, a higher day 30 Vδ1 concentration was associated with a lower incidence of cytomegalovirus reactivation in recipients. These results not only clarify the preservation of γδ T cell phenotypes and functional features by G-CSF mobilization but also suggest the importance of homeostatic γδ T cell content for immune recovery after alloHSCT.

    The importance of vitamin D in immunologic processes has recently emerged, but whether it has any impact on the course of allogeneic hematopoietic stem cell transplantation (HSCT) has not been determined. Reports indicate that HSCT recipients, particularly children, often suffer from vitamin D deficiency. This study investigated the role of vitamin D in 123 children undergoing HSCT from 2004 to 2011. Vitamin D (ie, serum calcidiol) was analyzed in collected cryostored samples. Patients were grouped according to pre-HSCT calcidiol level: insufficient (disease occurred more frequently in the vitamin D sufficient group (47% versus 30%, P = .05), whereas no difference was demonstrated for chronic graft-versus-host disease. The neutrophil granulocytes rose significantly faster in the vitamin D sufficient group. No difference in lymphocyte counts, immunoglobulin levels, or infectious disease burden during the first year post-HSCT were observed. Among children with malignancies, overall survival was significantly better in the sufficient group (87% versus 50%, P = .01). In addition, rejection (0% versus 11%, P = .06) and relapse (4% versus 33%, P = .03) rates were lower in patients with sufficient vitamin D levels. To conclude, vitamin D may have an important impact on the outcome of pediatric HSCT, particularly in patients with malignant disease. Further studies investigating whether vitamin D acts as an immunomodulator or is merely a surrogate marker of patient health or nutritional status are warranted.

    BACKGROUND: Current techniques of management of carinal lesions are not always satisfactory. Carinal transplantation, if feasible, would be valuable in certain circumstances. METHODS AND RESULTS: Carinal transplantation experiments were performed in dogs. In early cross transplant experiments there were problems in controlling ventilation and in obtaining satisfactory anastomoses, and the animals failed to live for even a few days. In seven subsequent experiments the carinal graft was removed from one dog and transplanted into a second dog. Two dogs lived for over four months with immunosuppression. CONCLUSION: The results suggest that carinal transplantation can succeed if (1) the calibre of the graft is matched with that of the recipient; (2) there is an abundant blood supply to the graft; (3) appropriate immunosuppression is provided; (4) ventilation is adequate during surgery.

    The goal of this study was to evaluate the influence of KIR-HLA genotypes on the outcome of patients undergoing treatment for haematological malignancies by non-T-depleted lymphocyte haematopoietic stem cell transplantation (HSCT) from HLA-matched sibling donors. The prospective study was conducted at the Center of Hematology, University of Campinas, and 50 patients and their donors were followed up from 2008 to 2014. KIR and HLA class I genes were genotyped and patients grouped based on the presence of KIR ligands combined with KIR genotype of their respective donors. Patients with all KIR ligands present (n=13) had a significantly higher (p=0.04) incidence of acute graft-versus-host-disease (GVHD) than patients with one or more KIR ligands missing (n=37). The overall survival following transplantation of patients with myeloid malignancies (n=27) was significantly higher (p=0.035) in the group with one or more KIR ligands missing (n=18) than in the group with all ligands present (n=9). Presence of KIR2DS2 was associated with a worsening of HSCT outcome while reactivation of cytomegalovirus (CMV) infection improved the outcome of patients with one or more KIR ligands missing. Our results indicate that KIR-HLA interactions affect the outcome of the HLA-matched transplantation, particularly in patients with myeloid malignancies. Copyright © 2016. Published by Elsevier Inc.

    Full Text Available The cure of hematologic disorders by allogeneic hematopoietic stem cell transplantation (HSCT is often associated with major complications resulting in poor outcome, including graft-versus-host disease (GVHD, relapse, and death. A novel composite endpoint of GVHD-free/relapse-free survival (GRFS in which events include grades 3-4 acute GVHD, chronic GVHD requiring systemic therapy, relapse, or death is censored to completely characterize the survival without mortality or ongoing morbidity. In this regard, studies attempting to identify the prognostic factors of GRFS are quite scarce. Thus, we reviewed 377 adult patients undergoing allogeneic HSCT between 2003 and 2013. The 1- and 2-year GRFS were 40.8% and 36.5%, respectively, significantly worse than overall survival and disease-free survival (log-rank p 2 (p 2 (p<0.001, being male (p=0.028, and hematologic malignancy (p=0.010 were significant for poor outcome. The events between 1-year GRFS and 2-year GRFS predominantly increased in relapsed patients. With prognostic factors of GRFS, we could evaluate the probability of real recovery following HSCT without ongoing morbidity.

    A significant number of survivors of hematopoietic stem-cell transplantation (HSCT) report enduring adverse effects of treatment, including illness-related post-traumatic stress disorder (PTSD) symptoms and general distress. We report results of a randomized clinical trial that tested the effects of a 10-session, telephone-administered cognitive-behavioral therapy (CBT) intervention on PTSD, depression, and distress symptoms. Survivors who had undergone HSCT 1 to 3 years earlier (N = 408) were assessed for study eligibility. Those who met study eligibility criteria (n = 89) completed a baseline assessment that included a clinical interview and self-report measures of PTSD symptoms (the primary outcome) and depression and general distress (the secondary outcomes). Next, they were randomly assigned to CBT or an assessment-only condition. Survivors in the CBT group completed 10 individual telephone-based CBT sessions (T-CBT) that included strategies to reduce PTSD symptoms, depression, and general distress. Follow-up assessments occurred at 6, 9, and 12 months after the baseline assessment. Linear mixed-model analyses revealed that, compared with HSCT survivors in the assessment-only condition, survivors who completed T-CBT reported fewer illness-related PTSD symptoms, including less avoidance (P PTSD symptoms and general distress.

    2017-05-01

    Invasive fungal infections (IFIs) following allogeneic hematopoietic stem cell transplantation (alloHSCT) are associated with a high mortality, and accordingly most alloHSCT recipients receive prophylaxis with antifungal agents. Despite some improvement in outcomes of IFIs over time, they continue to represent substantial clinical risk, mortality, and financial burden. Areas covered: We review the main pathogens responsible for IFIs in recipients of alloHSCT, current treatment recommendations, and discuss clinical and economic considerations associated with voriconazole prophylaxis of IFIs in these patients. Expert commentary: The clinical efficacy of voriconazole appears to be at least equivalent to other antifungal treatments, and generally well tolerated. Overall, benefit-risk balance is favorable, and findings from cost-effectiveness analyses support the use of voriconazole prophylaxis of IFIs in recipients of alloHSCT.

    Hepatic stellate cells (HSCs) migration, an important bioprocess, contributes to the development of liver fibrosis. Our previous studies have found the potent activity of dioscin against liver fibrosis by inhibiting HSCs proliferation, triggering the senescence and inducing apoptosis of activated HSCs, but the molecular mechanisms associated with cell migration were not clarified. In this work, iTRAQ (isobaric tags for relative and absolution quantitation)-based quantitative proteomics study was carried out, and a total of 1566 differentially expressed proteins with fold change ≥2.0 and p SDC-4 were carried out. The results of wound-healing, cell migration and western blotting assays indicated that dioscin significantly inhibit HSC-T6 cell migration through SDC-4-dependent signal pathway by affecting the expression levels of Fn, PKCα, Src, FAK, and ERK1/2. Specific SDC-4 knockdown by shRNA also blocked HSC-T6 cell migration, and dioscin slightly enhanced the inhibiting effect. Taken together, the present work showed that SDC-4 played a crucial role on HSC-T6 cell adhesion and migration of dioscin against liver fibrosis, which may be one potent therapeutic target for fibrotic diseases.

    Acute drug overdose, especially with paracetamol, may cause acute liver failure leading to registration for transplantation (ALFT). Population statistics and between-country differences for ALFT related to overdose have been poorly described. The aim of the present study was to evaluate overdose ALFT in the multi-country Study of Acute Liver Transplantation (SALT). All adult overdose-related ALFT, with or without suicidal intent, in France, Greece, Ireland, Italy, the Netherlands, Portugal and the UK between 2005 and 2007 were identified from liver transplant registries and hospital records. These were compared with whole-country and per capita use of paracetamol. Six hundred cases of ALFT were identified in 52 of 57 eligible transplant centres, of which 114 involved overdose (72 intentional, 10 non-intentional, 32 uncertain). Overdose represented 20% of all-cause ALFT: Ireland 52%, UK 28%, France 18%, the Netherlands 8%, and Italy 1%. Overdose ALFT were mostly females (61%), mean age 33.6 ± 10.9 years. A total of 111 (97%) of the overdoses involved paracetamol. Event rates ranged from one ALFT for 20.7 tons of paracetamol in Ireland, to one for 1074 tons in Italy and one case in 60 million inhabitants over 3 years in Italy to one case in 286 000 inhabitants per year in Ireland. Per-country event rates for non-overdose ALFT exposed to paracetamol were between 2.5 and 4.0 per million treatment-years sold.

    Intracoronary delivery of autologous bone marrow mononuclear cells is an interesting therapeutic promise for patients with heart failure of different etiologies. To evaluate the long-term safety and efficacy of this therapy in patients with dilated cardiomyopathy of different etiologies under optimal medical treatment. Prospective, open-label, controlled clinical trial. Of 23 consecutive patients, 12 were assigned to autologous bone marrow mononuclear cell intracoronary transplantation, receiving a mean dose of 8.19 ± 4.43 x 10(6) CD34+ cells. Mortality, cardiovascular readmissions and cancer incidence rate, changes in functional capacity, quality of life questionnaires and echocardiographic measures from baseline, were assessed at long-term follow-up (37.7 ± 9.7 months) in patients receiving or not the cells. No significant differences were observed in mortality, cardiovascular readmissions or cancer incidence rate amongst groups. An improvement in functional class and quality of life questionnaires in the transplanted group was observed (p transplantation of autologous bone marrow mononuclear cells is feasible and safe in patients with dilated cardiomyopathy of diverse etiologies. This therapy was associated to persistent improvements in functional class and quality of life. There was also a non-significant long-term improvement of left ventricular function.

    Full Text Available Abstract Introduction The purpose of this study was to identify graft osteoporosis post transplantation by micro-CT analysis, and the growth potential of growth plates in the transplanted limb. Methods Ten juvenile to juvenile and five juvenile to adult hind limb transplants were performed in male syngeneic Lewis rats. Upper tibial bone density in isochronograft and heterochronograft limbs was measured by 3D micro-CT and compared with that of the opposite non-operated limbs. Results We observed inferior bone quality (p Conclusions Age dependent alterations affect bone quality, resulting in post transplantation osteoporosis in heterochronografts, but not isochronografts. However, the growth plates of transplanted limbs retain their properties of longitudinal growth and continue to grow at the same rate.

    BACKGROUND Blood transfusions are common during hematopoietic stem cell transplantation (HSCT) and may contribute to lung injury. STUDY DESIGN AND METHODS This study examined the associations between red blood cell (RBC) and platelet (PLT) transfusions and idiopathic pneumonia syndrome (IPS) among 914 individuals who underwent myeloablative allogeneic HSCT between 1997 and 2001. Patients received allogeneic blood transfusions at their physicians' discretion. RBCs, PLTs, and a composite of “other” transfusions were quantified as the sum of units received each 7-day period from 6 days before transplant until IPS onset, death, or Posttransplant Day 120. RBC and PLT transfusions were modeled as separate time-varying exposures in proportional hazards models adjusted for IPS risk factors (age, baseline disease, irradiation dose) and other transfusions. Timing of PLT transfusion relative to myeloid engraftment and PLT ABO blood group (match vs. mismatch) were included as potential interaction terms. RESULTS Patients received a median of 9 PLT and 10 RBC units. There were 77 IPS cases (8.4%). Each additional PLT unit transfused in the prior week was associated with 16% higher IPS risk (hazard ratio, 1.16; 95% confidence interval, 1.09–1.23; p < 0.001). Recent RBC and PLT transfusions were each significantly associated with greater risk of IPS when examined without the other; only PLT transfusions retained significance when both exposures were included in the model. The PLT association was not modified by engraftment or ABO mismatch. CONCLUSION PLT transfusions are associated with greater risk of IPS after myeloablative HSCT. RBCs may also contribute; however, these findings need confirmation. PMID:24033082

    To investigate the safety and efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for myelodysplastic syndrome (MDS) and secondary acute myelogenous leukemia (MDS-AML) using conditioning regimen with busulfan (Bu) and increased-dose of fludarabine (ID-Flu). A total of 49 patients with MDS or MDS-AML were treated by allo-HSCT, the clinical data was analyzed retrospectively. All patients achieved hematopoietic reconstitution. Neutrophil engraftment was at 10 - 22 days (median 13 days), and platelet engraftment was at 8 - 66 days (median 16 days). The cumulative incidences of Ⅱ-Ⅳ degree acute graft-versus-host disease (GVHD), hemorrhagic cystitis (HC), and hepatic venous occlusive disease (VOD) were 28.6%, 14.3% and 2.0%, respectively. The transplant-related mortality (TRM) was only 4.1% at 100d and 8.2% at 1-92 months of followed-up (median 14 months) period. Overall survival (OS) and disease free survival (DFS) was 75.5%, 73.5%, respectively. Kaplan-Meier curve showed that 3-year OS and 3-year DFS was (71.1 ± 7.8)%, (66.7 ± 8.3)%, respectively, with a relapse incidence (RI) 16.3%. OS for MDS and MDS-AML was 81.5% and 68.2%, and RI in two settings was 3.7%, 31.8%, respectively. OS for MDS-AML at complete remission (CR) and non-CR subgroup was 83.3% and 50.0%, respectively, while cumulative RR was 16.7% and 50.0%, respectively. OS and RI except for non-CR subgroup were 82.1% and 7.7%. Univariate analysis showed that pre-HSCT disease status had correlation with OS (P=0.031), but age, decitabine in conditioning regimen, stem cell source, HLA matching, patient-donor gender, dose of mononuclear cells and GVHD had no correlation with OS. Bu/ID-Flu conditioning regimen for MDS and MDS-AML has high efficiency, fewer complications, lower toxicity and TRM. The OS and DFS were higher and RI was lower except for refractory MDS-AML patients. The regimen is valuable for clinical application.

    Full Text Available The advantage of using a Human Leukocyte Antigen (HLA-mismatched related donor is that almost every patient who does not have a HLA-identical donor or who urgently needs hematopoietic stem cell transplantation (HSCT has at least one family member with whom shares one haplotype (haploidentical and who is promptly available as a donor. The major challenge of haplo-HSCT is intense bi-directional alloreactivity leading to high incidences of graft rejection and graft-versus-host disease (GVHD. Advances in graft processing and in pharmacologic prophylaxis of GVHD have reduced these risks and have made haplo-HSCT a viable alternative for patients lacking a matched donor. Indeed, the haplo-HSCT  has spread to centers worldwide even though some centers have preferred an approach based on T cell depletion of G-CSF-mobilized peripheral blood progenitor cells (PBPCs, others have focused on new strategies for GvHD prevention, such as G-CSF priming of bone marrow and robust post-transplant immune suppression or post-transplant cyclophosphamide (PTCY. Today, the graft can be a megadose of T-cell depleted PBPCs or standard dose of unmanipulated bone marrow and/or PBPCs.  Although haplo-HSCT modalities are based mainly on high intensity conditioning regimens, recently introduced reduced intensity regimens (RIC   showed promise in decreasing early transplant-related mortality (TRM, and extending the opportunity of HSCT to an elderly population with more comorbidities. Infections are still mostly responsible for toxicity and non-relapse mortality due to prolonged immunosuppression related, or not, to GVHD. Future challenges lie in determining the safest preparative conditioning regimen, minimizing GvHD and promoting rapid and more robust immune reconstitution.

    Full Text Available O transplante de pâncreas e de ilhotas pancreáticas vem apresentando grande desenvolvimento nos últimos anos. O isolamento das ilhotas em cápsulas com membrana semi-permeáveis pode ser tratamento de escolha para o diabetes, pois dispensa o uso de imunossupressores. O material ideal para a confecção de uma cápsula para o isolamento celular ainda permanece um sonho. Um novo material a base de látex natural foi implantado no subcutâneo de ratos normais e diabéticos para estudar a biocompatibilidade e a neoformação vascular. A análise após 21 dias de implante mostrou intensa formação capilar na interface membrana-tecido e pouco tecido fibrótico. Estes achados iniciais mostram que o material pode ter algum potencial para a confecção de dispositivos de isolamento celular.There have been great developments in pancreas and pancreatic islet cell transplantion in the last few years. The isolation of the islet cells in capsules with semi-permeable membranes may become ideal means of treating diabetes, and the use of immunossuppression could be avoided. The ideal material for the confection of the capsules has remained a dream. A new material derived from natural latex was implanted in the subcutaneous tissue of normal and diabetic rats to study the biocompatibility and the vascular neoformation. After 21 days, an analysis of the implant showed intense vascular neoformation on the membrane-tissue interface and little fibrotic tissue. The inicial results show great promise for utilization of this material in capsules for the isolation of cells.

    Forty patients with high-risk hematologic malignancies, median age 9 years, underwent haploidentical-HSCT from April 2005 to April 2015. Seventeen patients were transplanted with CD3-depleted PBSCs by negative selection (TCD group) following a reduced-intensity conditioning regimen (RIC), and 23 patients received T-cell-replete PBSCs followed by post-transplantation cyclophosphamide (PT-Cy group) after myeloablative conditioning (n=16) or RIC (n=7). Outcomes are reported for the TCD and PT-Cy recipients, respectively. Engraftment was achieved in 88% versus 100%. Median time to neutrophils>500/μL was 10 days versus 15 days. Platelets>20 000/μL occurred at a median of 16 days versus 20 days, respectively. Transplant-related mortality (TRM) was 24% versus 26% at 1 year. The cumulative incidence (CI) of grade III-IV acute GvHD was 7% versus 5%, and chronic GvHD 9% versus 53% (P=0.029). Relapse at 2 years was 31% versus 24%. Actuarial overall survival rates at 2 years were 47% versus 48%. Causes of death were infections (n=3), sinusoidal obstructive syndrome (n=4), acute GvHD (n=2) and relapse (n=9). These results indicate that haploidentical-HSCT is feasible in Uruguay. The TRM rate is of concern and should be the focus of continuing attention. Chronic GvHD risk was higher in the PT-Cy approach, so modifications are justified.

    There are no Canadian immunization guidelines for children treated for malignancy. Guidelines do exist for patients who underwent hematopoietic stem cell transplant (HSCT), but they provide broad timeframes for initiating vaccination; there is no standard schedule. The optimal approach to immunization in these populations is unclear. We sought to describe immunization practices at Canadian Pediatric Hematology/Oncology centers. A 43-item online questionnaire was distributed to the 16 programs in the C(17) research network of pediatric hematology/oncology centers to capture information on timing and criteria for immunization of patients with acute lymphocytic leukemia (ALL) and those who have undergone HSCT. At each center, 1-2 physicians or pharmacists completed the survey to reflect center-wide immunization practices. Responses were received from 11/16 (69%) programs; 11 respondents reported on practices for patients with ALL and 9 reported on practices for patients who are post-HSCT. In 5/11 ALL programs (45%) re-immunization is recommended routinely after chemotherapy, starting 3-6 months post-chemotherapy. In HSCT programs, timing of pneumococcal conjugate vaccination (PCV) varied from 3 months post-HSCT (4 programs) to 12 months post-HSCT (4 programs). Live vaccines were administered 24 months post-HSCT in 8/9 programs. All HSCT programs considered graft-versus-host-disease and 7 considered discontinuation of immunosuppression in immunization decisions. Pediatric hematology/oncology programs were divided in regards to re-immunization of patients with ALL post-chemotherapy. After HSCT, timing of PCV administration varied, with 4 programs initiating immunization later than Canadian guidelines recommend (3-9 months post-HSCT). These findings suggest a need to standardize immunization practices in these populations.

    Allogeneic hematopoietic stem cell transplantation (HSCT) is curative for many patients with severe benign and malignant hematologic disorders. The success of allogeneic HSCT is limited by the development of transplant-related complications such as acute graft-versus-host disease (GvHD). Early pre-clinical studies suggested that intestinal microflora contribute to the pathogenesis of acute GvHD, and that growth suppression or eradication of intestinal bacteria prevented the development of acute GvHD even in MHC-mismatched transplants. These observations led to the practice of gut decontamination (GD) with oral non-absorbable antibiotics in patients undergoing allogeneic HSCT as a method of acute GvHD prophylaxis. Microbiome studies in the modern sequencing era are beginning to challenge the benefit of this practice. In this review, we provide a historical perspective on the practice of GD and highlight findings from the limited number of clinical trials evaluating the use of GD for acute GvHD prevention in allogeneic HSCT patients. In addition, we examine the role of the gut microbiota in allogeneic HSCT in the context of recent studies linking the microflora to regulation of intestinal immune homeostasis. We discuss the implications of these findings for future strategies to reduce acute GvHD risk by selective manipulation of the microbiota.

    Full Text Available Sickle Cell Anaemia (SCA is the most common inherited blood disorder and is associated with severe morbidity and decreased survival. Allogeneic Haematopoietic Stem Cell Transplantation (HSCT is the only curative approach. Nevertheless the decision to perform a marrow transplant includes the risk of major complications  and mortality transplant related. The infections represent the main cause of mortality for SCA patients undergoing transplant. Invasive Pulmonary Aspergillosis (IPA is a devastating opportunistic infection and remains a significant cause of morbidity and mortality in HSCT recipients. Data regarding IPA in the setting of SCA are lacking. In the present report,  we describe a patient with SCA who developed IPA after allogeneic bone marrow transplant. The fungal infection was treated by systemic antifungal therapy in addition to the surgery, despite  mild chronic GVHD and with continuing immunosuppression therapy. This case shows that IPA occurring in bone marrow recipient with SCA can be successful treated

    Full Text Available Allogeneic stem cell transplantation (allo-HSCT is one of the curative treatments for hematologic malignancies, but is hampered by severe complications, such as acute or chronic graft-versus-host-disease (aGvHD; cGvHD and infections. CD34-selcetion of stem cells reduces the risk of aGvHD, but also leads to increased infectious complications and relapse. Thus, we studied the efficacy, safety and feasibility of transfer of gene modified donor T-cells shortly after allo-HSCT in two clinical trials between 2002 and 2007 and here we compare the results to unmodified donor leukocyte transfusion (DLI. The aim of these trials was to provide patients with the protection of T-cells after T-cell-depleted allo-HSCT in the matched or mismatched donor setting with an option to delete transduced T-cells, if severe aGvHD occurred within the trial period. Donor-T-cells were transduced with the replication-deficient retrovirus SFCMM-3, expressing HSV-Tk and the truncated LNGFR for selection of transduced cells. Transduced cells were transfused either after day +60 (matched donors or on day +42 (haploidentical donors.Nine patients were included in the first trial (MHH; 2002 until 2007 2 were included in TK007 (2005-2009 and 6 serve as a control group for outcome after haploidentical transplantation without HSV-TK-transduced DLI. Three patients developed acute GvHD, two had grade I of the skin, one had aGvHD on day +131 (post-HSCT; +89 post-HSV-Tk DLI grade II, which was successfully controlled by ganciclovir (GCV. Donor chimerism was stabilized after transfusion of the transduced cells in all patients treated. Functionality of HSV-Tk gene expressing T-cells was shown by loss of bcr-abl gene expression as well as by control of cytomegalovirus-reactivation. To date, 6patients have relapsed and died, 2 after a second HSCT without T-cell depletion or administration of unmodified T-cells. Eleven patients (7 post-HSV-Tk DLI are alive and well to date.

    Controversy exists regarding whether oral cryotherapy can prevent oral mucositis (OM) in patients with hematological malignancies undergoing hematopoietic stem cell transplantation (HSCT). The aim of the present meta-analysis was to evaluate the efficacy of oral cryotherapy for OM prevention in patients with hematological malignancies undergoing HSCT. PubMed and the Cochrane Library were searched through October 2014. Randomized controlled trials (RCTs) comparing the effect of oral cryotherapy with no treatment or with other interventions for OM in patients undergoing HSCT were included. The primary outcomes were the incidence, severity, and duration of OM. The secondary outcomes included length of analgesic use, total parenteral nutrition (TPN) use, and length of hospital stay. Seven RCTs involving eight articles analyzing 458 patients were included. Oral cryotherapy significantly decreased the incidence of severe OM (RR = 0.52, 95% CI = 0.27 to 0.99) and OM severity (SMD = -2.07, 95% CI = -3.90 to -0.25). In addition, the duration of TPN use and the length of hospitalization were markedly reduced (SMD = -0.56, 95% CI = -0.92 to -0.19; SMD = -0.44, 95% CI = -0.76 to -0.13; respectively). However, the pooled results were uncertain for the duration of OM and analgesic use (SMD = -0.13, 95% CI = -0.41 to 0.15; SMD = -1.15, 95% CI = -2.57 to 0.27; respectively). Oral cryotherapy is a readily applicable and cost-effective prophylaxis for OM in patients undergoing HSCT.

    Full Text Available Hematopoietic stem cell transplantation (HSCT is a lifesaving expensive medical procedure. Hence, more transplants are performed in more affluent countries. The impact of economic factors on patient outcome is less defined. We analyzed retrospectively a defined cohort of 102,549 patients treated with an allogeneic (N = 37,542; 37% or autologous (N = 65,007; 63% HSCT. They were transplanted by one of 404 HSCT centers in 25 European countries between 1999 and 2006. We searched for associations between center-specific microeconomic or country-specific macroeconomic factors and outcome. Center patient-volume and center program-duration were significantly and systematically associated with improved survival after allogeneic HSCT (HR 0·87; 0·84–0·91 per 10 patients; p < 0·0001; HR 0·90;0·85–0·90 per 10 years; p < 0·001 and autologous HSCT (HR 0·91;0·87–0·96 per 10 patients; p < 0·001; HR 0·93;0·87–0·99 per 10 years; p = 0·02. The product of Health Care Expenditures by Gross National Income/capita was significantly associated in multivariate analysis with all endpoints (R2 = 18%; for relapse free survival after allogeneic HSCT. Data indicate that country- and center-specific economic factors are associated with distinct, significant, systematic, and clinically relevant effects on survival after HSCT. They impact on center expertise in long-term disease and complication management. It is likely that these findings apply to other forms of complex treatments.

    The successful reconstitution of adaptive immunity to human cytomegalovirus (CMV) in hematopoietic stem cell transplantation (HSCT) recipients is central to the reduction of viral reactivation-related morbidity and mortality. Here, we characterized the magnitude, specificity, phenotype, function, and clonotypic composition of CMV-specific T-cell responses in 18 donor-recipient pairs both before and after HSCT. The principal findings were: (1) the specificity of CMV-specific T-cell responses in the recipient after HSCT mirrors that in the donor; (2) the maintenance of these targeting patterns reflects the transfer of epitope-specific T-cell clonotypes from donor to recipient; (3) less differentiated CD27(+)CD57(-) CMV-specific memory T cells are more likely to persist in the recipient after HSCT compared with more terminally differentiated CD27(-) CD57(+) CMV-specific memory T cells; (4) the presence of greater numbers of less differentiated CD8(+) CMV-specific T cells in the donor appears to confer protection against viral reactivation in the recipient after HSCT; and (5) CMV-specific T cells acquire a more differentiated phenotype and a restricted functional profile after HSCT. Overall, these findings define the immunologic factors that influence the successful adoptive transfer of antigen-specific T-cell immunity during HSCT, which enables the identification of recipients at particular risk of CMV reactivation after HSCT.

    The development of secondary malignancies is a potential long-term complication after haematopoietic stem cell transplantation (HSCT). In particular, a higher incidence of oral squamous cell carcinoma (OSCC) has been reported in patients experiencing chronic graft versus host disease (cGvHD) secondary to HSCT. This report describes the development of two synchronous SCC of the buccal mucosa in a young female patient treated with HSCT for beta thalassemia major. She had undergone HSCT at the age of 9 years and developed oral GvHD 6 months after transplant. 17 years after HSCT she developed two synchronous carcinomatous lesions on the tongue and floor of the mouth. The current case highlights the association between oral cGvHD and OSCC, and the possible development of OSCC in young patients even many years after HSCT. This evidence suggests closer follow-up for all patients treated with HSCT who developed cGvHD, and more effective strategies to prevent and treat cGvHD.

    To study the factors affecting the time to onset of ocular graft-versus-host disease (GVHD) in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). A retrospective chart review of 200 patients with ocular GVHD was performed to evaluate the association between various donor-recipient characteristics and the time to onset of ocular GVHD after allo-HSCT. The median time to onset of chronic ocular GVHD after allo-HSCT was 293 days (range, 26-2308 days). Patients receiving fully human leukocyte antigen (HLA)-matched transplants had a delayed onset of ocular GVHD (median, 294 days) compared with mismatched transplants (219 days; P = 0.029). HLA-matched transplants from related donors had delayed onset of ocular GVHD (307 days) compared with HLA-matched (286 days; P = 0.168) and HLA-mismatched (231 days; P = 0.015) transplants from unrelated donors. Ocular GVHD followed systemic GVHD in 76% of patients but preceded systemic disease in 7%, occurred concurrently in 15%, and was not associated with systemic GVHD in 2% of patients. The time elapsed between the occurrence of systemic and ocular GVHD was significantly longer in matched-related transplants (250 days) than in matched-unrelated transplants (120 days; P = 0.004). The onset of ocular GVHD after allo-HSCT is variable and is influenced by donor-recipient matching characteristics. In the majority of patients with GVHD, ocular involvement follows the occurrence of systemic manifestations; however, importantly, it can also precede or develop independently of systemic disease in a minority of patients. Regular ophthalmic follow-up is recommended after allo-HSCT regardless of concurrent systemic GVHD status.

    Full Text Available Abstract Although the past few decades have shown an improvement in the survival and complication-free survival rates in patients with beta-thalassemia major and gene therapy is already at an advanced stage of experimentation, hematopoietic stem cell transplantation (HSCT continues to be the only effective and realistic approach to the cure of this chronic non-malignant disease. Historically, human leukocyte antigen (HLA-matched siblings have been the preferred source of donor cells owing to superior outcomes compared with HSCT from other sources. Nowadays, the availability of an international network of voluntary stem cell donor registries and cordon blood banks has significantly increased the odds of finding a suitable HLA matched donor. Stringent immunogenetic criteria for donor selection have made it possible to achieve overall survival (OS and thalassemia-free survival (TFS rates comparable to those of sibling transplants. However, acute and chronic graft-versus-host disease (GVHD remains the most important complication in unrelated HSCT in thalassemia, leading to considerable rates of morbidity and mortality for a chronic non-malignant disease. A careful immunogenetic assessment of donors and recipients makes it possible to individuate appropriate strategies for its prevention and management. This review provides an overview on recent insights about immunogenetic factors involved in GVHD, which seem to have a potential role in the outcome of transplantation for thalassemia.

    Organ shortage remains a major barrier to transplantation. While many efforts have focused on educating the general population regarding donation, few studies have examined knowledge regarding donation and donor registration rates among waitlisted candidates. We aimed to determine waitlisted patients' willingness to donate, elucidate attitudes surrounding organ allocation, and identify barriers to donation. A cross-sectional survey was distributed to assess demographics, knowledge regarding organ donation, and attitudes regarding the allocation process. Responses from 225 of 579 (39%) waitlisted patients were collected. 71 respondents (32%) were registered donors, while 64 patients (28%) noted no interest in participating in donation. 19% of respondents felt their medical treatment would change by being a donor, while 86 patients (38%) felt their condition precluded them from donation. 40 patients (18%) felt they should be prioritized on the waitlist if they agreed to donate. A minority of patients (28%) reported discussion of organ donation with their physician. Waitlisted candidates constitute a population of willing, though often unregistered, organ donors. Moreover, many endorse misconceptions regarding the allocation process and their donation eligibility. In a population for which transplantation is not always possible, education is needed regarding organ donation among waitlisted patients, as this may enhance donation rates. PMID:27582432

    To evaluate the long-term efficacy of amniotic membrane transplantation for ocular surface reconstruction in the surgical management of ocular surface squamous neoplasia (OSSN). OSSN in 21 patients (7 female, 14 male patients) was managed with excisional biopsy, cryotherapy, corneal epitheliectomy with absolute alcohol application when the cornea is involved, lamellar sclerectomy and adjunctional absolute alcohol application to the base when episclera is involved, and ocular surface reconstruction with cryopreserved amniotic membrane transplantation. Tumor control and complications were evaluated. The mean age of the patients was 62.42 ± 20.9 (range, 16-84). The average diameter of the base of the tumors was 13.1 ± 4.8 (range, 9-21) mm and complete removal was achieved in all cases as revealed histopathologically. Ocular surface healing was achieved in all cases. At the postoperative period, limbal stem cell deficiency in three eyes and mild symblepharon in one eye were detected. In a mean follow-up of 30.95 ± 18.8 (range, 13-75) months, no recurrence was detected. For large or multifocal conjunctival tumors, the reconstruction of ocular surface and fornix is challenging. The amniotic-membrane use to repair conjunctival defects larger than 10 mm is a safe and effective technique with minimal complications allowing surgeons to make large enough excisions.

    The number of living-donor liver transplants has been increasing due to the growing discrepancy between the number of patients on wait lists for liver transplant and the availability of deceased donations. Evaluations of potential liver donors should ensure the safety of the surgical procedure for both the donor and recipient. Liver biopsy is the criterion standard for selecting optimal donors. In this study, we evaluated the importance of preoperative liver biopsy in selecting donor candidates. We evaluated the data of 612 living-related liver donor candidates who received liver biopsies between January 2001 and June 2017 at our center. In the 612 liver donor candidates (328 male, 284 female; age range, 18-69 years), 416 liver biopsies (68%) were reported as normal and 196 liver biopsies (32%) had pathologic findings. Of 196 donors with pathologic findings, 86 (44%) had fatty changes and 24 (12%) had portal inflammation. The high rate of pathologic findings in liver biopsy of healthy-appearing donor candidates indicated the importance of liver biopsy in the preoperative evaluation of donors.

    The National Marrow Donor Program and Center for International Blood and Marrow Transplant Research provided guidelines for the use of anti-HLA antibodies and HLA-DP-mismatched loci in unrelated donor hematopoietic stem cell transplantation (HSCT). However, a deeper understanding of other potentially useful biomarkers for predicting clinical outcomes in HLA-A, -B, -C, -DRB1, -DQB1, and -DQA1 (12/12)-matched unrelated donor HSCT is needed to further improve clinical outcomes. We tested HLA genotyping for 123 pairs of patients and donors. Anti-HLA antibodies using the Luminex method was applied to 123, 117, and 106 serum samples collected before and 1 month and 3 months after transplantation. The presences of anti-HLA antibodies at the 3 time points were 37.4% (46 of 123), 40.2% (47 of 117), and 22.6% (24 of 106). Mismatch of HLA-DPB1 and/or DPA1 allele between patient-donor pairs was 83.6% (92 of 110). Patients with anti-HLA antibodies had delayed platelet recovery. The presence of anti-HLA antibodies and their dynamic changes after transplantation were associated with increased occurrence of grades II to IV acute and chronic graft-versus-host disease (GVHD), higher treatment-related mortality, and reduced overall survival (OS) and disease-free survival, especially in acute myeloid leukemia and myelodysplastic syndrome patients. Multivariate analysis showed that presence of anti-HLA antibodies before transplantation was a risk factor for GVHD and OS. Furthermore, HLA-DP loci-matched subgroup showed a trend towards a lower rate of acute GVHD and a higher OS in the anti-HLA Abs-negative group. Our results suggest that dynamic changes of anti-HLA antibodies independently predict for a negative outcome of HSCT, independent of HLA-DP loci mismatches. Routine monitoring for anti-HLA antibody dynamics should be conducted before and after HSCT. Copyright © 2016 American Society for Blood and Marrow Transplantation. Published by Elsevier Inc.

    Allogeneic hematopoietic stem cell transplantation (HSCT) can lead to significant changes to the HIV reservoir and HIV immune responses, indicating that further characterization of HIV-infected patients undergoing HSCT is warranted. We studied 3 patients who underwent HSCT after either reduced intensity conditioning or myeloablative conditioning regimen. We measured HIV antigens and antibodies (Ag/Ab), HIV-specific CD4 T-cell responses, HIV RNA, and DNA in plasma, peripheral blood mononuclear cells, isolated CD4 T cells from peripheral blood, and lymph node cells. The patients remained on antiretroviral therapy throughout the follow-up period. All patients have been in continued remission for 4-6 years post-HSCT. Analyses of HIV RNA and DNA levels showed substantial reductions in HIV reservoir-related measurements in all 3 patients, changes in immune response varied with pronounced reductions in 2 patients and a less dramatic reduction in 1 patient. One patient experienced unexpected viral rebound 4 years after HSCT. These 3 cases highlight the substantial changes to the HIV reservoir and the HIV immune response in patients undergoing allogeneic HSCT. The viral rebound observed in 1 patient indicates that replication competent HIV can re-emerge several years after HSCT despite these marked changes.

    Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is considered the cornerstone in treatment of hematological malignancies. However, relapse of the hematological disease after allo-HSCT remains a challenge and is associated with poor long-term survival. Chimeric antigen receptor redirected T cells (CAR-T cells) can lead to disease remission in patients with relapsed/refractory hematological malignancies. However, the therapeutic window for infusion of CAR-T cells post allo-HSCT and its efficacy are debatable. In this review, we first discuss the use of CAR-T cells for relapsed cases after allo-HSCT. We then review the toxicities and the occurrence of graft-versus-host disease in relapsed patients who received CAR-T cells post allo-HSCT. Finally, we review clinical trial registrations and the therapeutic time window for infusion of CAR-T cells post allo-HSCT. The treatment of allogeneic CAR-T cells is beneficial for patients with relapsed B cell malignancies after allo-HSCT with low toxicities and complications. However, multicenter clinical trials with larger sample sizes should be performed to select the optimal therapeutic window and confirm its efficacy.

    Despite the successes of tyrosine kinase inhibitors (TKIs) in improving outcomes in patients with chronic myeloid leukemia (CML) and Philadelphia-positive acute lymphoblastic leukemia (Ph + ALL), allogeneic hematopoietic stem cell transplantation (HSCT) continues to be an important and potentially curative option for selected patients with either disease. After HSCT, TKIs are increasingly being used to treat or prevent disease relapse, and practice patterns suggest that these TKIs are often chosen empirically without regard to pre-HSCT mutation status. We investigated whether ABL kinase domain mutations persist after transplantation and, thus, whether pre-HSCT mutation status should inform the selection of post-HSCT TKIs in these patients. We retrospectively analyzed adults who underwent allogeneic HSCT for CML and Ph + ALL at our institution between 2000 and 2010, and we identified subjects who had detectable BCR-ABL transcripts by polymerase chain reaction (PCR), as well as available RNA for Sanger sequencing of the ABL kinase domain, in both the pre- and post-HSCT settings. In total, 95 CML and 20 Ph + ALL patients with positive PCR transcripts were identified, of which 10 (10.5%) and 4 (20.0%), respectively, were found to have pre-HSCT ABL kinase mutations known to confer TKI resistance. In 9 (64.2%) of these 14 patients, the same kinase mutation was also detectable at an average time of 191 days after HSCT. Seven (50.0%) of the 14 harboring mutations had relapsed/refractory disease by last follow-up, of which, in retrospect, 6 had received a predictably ineffective TKI within the first 100 days after transplantation based on our mutation analysis. These data support the idea that pre-existing mutations in the ABL kinase domain, frequently associated with resistance to TKIs and prevalent in a transplantation population, are persistently detectable in the majority of patients after transplantation. We propose that such resistance patterns should be considered

    Breakthrough viridans streptococcal bacteremia (VSB) in patients with hematological malignancy receiving levofloxacin prophylaxis is a major blood stream infection (BSI) occurring during febrile neutropenia. However, clinical data focused on VSB in allogeneic hematopoietic stem cell transplant (allo-HSCT) recipients are lacking. The medical records of allo-HSCT recipients who received oral levofloxacin prophylaxis between January 2011 and August 2013 at Toranomon Hospital were reviewed to evaluate breakthrough VSB. Stored viridans streptococcal (VGS) species were identified by using sodA gene sequencing, and were assessed for drug susceptibility. Among the 184 allo-HSCT recipients on levofloxacin prophylaxis, 28 (15.2 %) experienced breakthrough VSB. All of the 28 recipients with VSB were treated with a cefepime-based or piperacillin/tazobactam-based regimen. The susceptibility rates of the VGS strains for levofloxacin, cefepime, piperacillin/tazobactam, meropenem, and vancomycin were 0 %, 95 %, 100 %, 100 %, and 100 %, respectively. Both the MIC50 (minimum inhibitory concentration) and the MIC90 of ceftazidim (0.5 μg/mL and 2 μg/mL, respectively) were higher than the MIC90 of all the other anti-pseudomonal beta-lactams (APBLs). Only 1 VGS strain had a penicillin MIC ≥ 2 μg/mL by the Etest (3.6 %). There were no cases with acute respiratory distress syndrome (ARDS) that was associated with VSB, although the rate of viridans group streptococcal shock syndrome was high (26 %). The crude 30-day mortality rate in the VSB group (10.7 %) did not differ significantly from that in the BSI without VSB group (9.3 %) or non-BSI group (7.0 %) (P = 0.77). Also, VSB was not a risk factor for all-cause mortality up to 60 days following allo-HSCT (P = 0.43). APBL with increased anti-VGS activity (APBL-VA) monotherapy would typically be optimal for treating the VGS strains in this setting. Indication of adding an empiric anti-gram-positive agent to

    Invasive aspergillosis (IA) is a major cause of death after hematopoietic stem cell transplantation (HSCT). The goal of this retrospective and consecutive survey was to assess prognostic factors of death due to IA after HSCT at the time of diagnosis of IA. All 64 health care centers affiliated with the Société Française de Greffe de Moelle et de Thérapie Cellulaire were contacted to participate in this study of all proven or probable cases of IA that occurred among HSCT recipients in 2002. Data for 51 cases (41 involving allogeneic HSCT and 10 involving autologous HSCT) were collected from patient records and included diagnostic and therapeutic features of IA, outcome, presence of hematological disease, and transplantation data. Cox models were applied to risk factors for death attributed to IA that were initially identified using the usual tests. The proportion of deaths attributed to IA within 4 months after diagnosis was 0.62 (95% confidence interval, 0.47-0.76). Seven factors assessed at diagnosis were determined to be strongly related to death due to IA: age of 12-35 years, dissemination of IA, presence of a pleural effusion, monocyte count of or =2 mg/kg at the time of diagnosis, and uncontrolled graft-versus-host disease.Conclusions. Our study explored potential risk factors for death due to IA among HSCT recipients as a reference for investigation in larger future studies. These factors should help to identify HSCT recipients who would benefit from more-aggressive antifungal therapies.

    Full Text Available Objective: Patients receiving hematopoietic stem cell transplantation (HSCT are exposed to highly immunosuppressive conditions and bloodstream infections (BSIs are one of the most common major complications within this period. Our aim, in this study, was to evaluate the epidemiology of BSIs in these patients retrospectively. Materials and Methods: The epidemiological properties of 312 patients with HSCT were retrospectively evaluated. Results: A total of 312 patients, followed between 2000 and 2011, who underwent autologous (62% and allogeneic (38% HSCT were included in the study. The most common underlying malignancies were multiple myeloma (28% and Hodgkin lymphoma (21.5%. A total of 142 (45% patients developed at least 1 episode of BSI and 193 separate pathogens were isolated from the blood cultures. There was a trend of increase in the numbers of BSIs in 2005-2008 and a relative increase in the proportion of gram-positive infections in recent years (2009-2011, and central venous catheter-related BSI was found to be most common source. Coagulase-negative staphylococci (49.2% and Acinetobacter baumannii (8.8% were the most common pathogens. Extended-spectrum beta-lactamase-producing strains were 23% and 22% among Escherichia coli and Klebsiella spp. isolates, respectively. Quinolone resistance was detected in 10% of Enterobacteriaceae. Resistance to carbapenems was not detected in Enterobacteriaceae, while it was seen at 11.1% and 23.5% in Pseudomonas and Acinetobacter strains, respectively. Conclusion: A shift was detected from gram-negative bacteria to gram-positive in the etiology over the years and central lines were the most common sources of BSIs.

    2012-01-01

    Full Text Available Emery-Dreifuss muscular dystrophy (EDMD is a hereditary neuromuscular disorder characterized by slowly progressive muscle weakness, early contractures, and dilated cardiomyopathy. We reported an uneventful general anaesthesia using total intravenous anaesthesia (TIVA for cardiac transplantation in a 19-year-old woman suffering from EDMD. In vitro contracture test results of two pectoralis major muscle bundles of the patient suggest that exposition to triggering agents does not induce a pathological sarcoplasmic calcium release in the lamin A/C phenotype. However, due to the lack of evidence in the literature, we would recommend TIVA for patients with EDMD if general anaesthesia is required.

    Due to organ shortage in lung transplantation (LTx), donation after circulatory death (DCD) has been implemented in several countries, contributing to an increasing number of organs transplanted. We sought to assess long-term outcomes after LTx with organs procured following circulatory death in comparison with those obtained from donors after brain death (DBD). Between January 2007 and November 2013, 302 LTxs were performed in our institution, whereby 60 (19.9%) organs were retrieved from DCD donors. We performed propensity score matching (DCD:DBD = 1:2) based on preoperative donor and recipient factors that were significantly different in univariate analysis. After propensity matching, there were no statistically significant differences between the groups in terms of demographics and preoperative donor and recipient characteristics. There were no significant differences regarding intraoperative variables and total ischaemic time. Patients from the DCD group had significantly higher incidence of primary graft dysfunction grade 3 at the end of the procedure (P = 0.014), and significantly lower pO2/FiO2 ratio during the first 24 h after the procedure (P = 0.018). There was a trend towards higher incidence of the need for postoperative extracorporeal life support in the DCD group. Other postoperative characteristics were comparable. While the overall cumulative survival was not significantly different, the DCD group had significantly poorer results in terms of bronchiolitis obliterans syndrome (BOS)-free survival in the long-term follow-up. Long-term results after LTx with organs procured following DCD are in general comparable with those obtained after DBD LTx. However, patients transplanted using organs from DCD donors have a predisposition for development of BOS in the longer follow-up. © The Author 2015.

    The aim of hematopoietic stem cell transplantation (HSCT) is to cure patients of malignancies, autoimmune diseases, and immunodeficiency disorders by redirecting the immune system: the often described graft-versus-leukemia (GVL) or graft-versus-tumor (GVT) effects. Unfortunately, fulfillment of this goal is often hampered by relapse of the underlying disease, graft-versus-host disease (GVHD), or severe opportunistic infections, which account for the majority of post-transplantation deaths. Moreover, studies of long-term survivors of transplantation indicate an accelerated immune aging due to the transplantation procedure itself, preceding chemo- or radiotherapy, and acute and chronic GVHD. Significant advances have been made towards overcoming these obstacles by enhancing immune reconstitution with hematopoietic growth factors (HGFs) such as granulocyte colony-stimulating factor (G-CSF) or erythropoietin (EPO) or through the application of cytokines. In addition, there are approaches to promote the thymic-dependent development of naive T cells, which are prepared for the interaction with a multitude of pathogens. Examples are the application of keratinocyte growth factor (KGF), neuroendocrine hormones such as growth hormone or prolactin, sex hormone ablation, or the invention of a three-dimensional artificial thymus based on a cytomatrix. Might these measures result in a higher rate of healthy and fully recovered patients? Here we review progress in each of these areas.

    To describe survival and neurological outcomes after HSCT for these disorders. Seven CALD, 2 MLD and 2 MPS-IH patients underwent HSCT between 2007 and 2014. Neurological examinations, magnetic resonance imaging, molecular and biochemical studies were obtained at baseline and repeated when appropriated. Favorable outcomes were obtained with 4/5 related and 3/6 unrelated donors. Two patients died from procedure-related complications. Nine transplanted patients were alive after a median of 3.7 years: neurological stabilization was obtained in 5/6 CALD, 1/2 MLD, and one MPS-IH patient. Brain lesions of the MPS-IH patient were reduced four years after HSCT. Good outcomes were obtained when HSCT was performed before adulthood, early in the clinical course, and/or from a related donor.

    Awareness among the medical students and junior doctors about organ donation and transplantation (ODT) may play an important role in increasing organ donor pool. This study surveys the knowledge, perceptions, and attitudes of ODT among the U.K. junior doctors and attempts to identify their educational needs. To our knowledge, this is first such study in the United Kingdom. A cross-sectional online survey was conducted among 1,696 junior doctors (809 foundation and 887 core trainees). A 36-point questionnaire explored the junior doctor's knowledge, perceptions, and attitudes toward ODT. There were 523 respondents (30.8%). Majority were foundation trainees (58.9%). Only 29.6% had previous exposure to transplantation, which reflected in their poor knowledge on the basics of ODT. Only 47.0% of the respondents were aware that consent from next of kin or family is sought for all deceased organ donation. Those registered as organ donor (69.8%) had better knowledge, perceptions, and attitudes in comparison to those not registered. Majority (84.1%) felt that they were inadequately exposed to ODT, and 96.8% stated that ODT should be part of undergraduate curriculum. Junior doctors in the United Kingdom have limited knowledge about ODT. Although subjected to investigators bias, the results demonstrate that junior doctors' perceptions and attitudes toward ODT were favorable. Majority felt that their ODT knowledge was inadequate and suggested the need for a change in undergraduate ODT curriculum. Increasing knowledge and awareness among junior doctors may help to improve the continuing organ shortage for transplantation.

    To investigate the effects of blueberry on the apoptosis, expression of Bcl-2 and Bax in rat hepatic stellate cell (HSC-T6). 10% blueberry serum at low, middle and high dose, 10% Fu-Fang-Bie-Jia-Ruan-Gan tablet serum and 10% saline serum were prepared by method of serum pharmacology. Subcultured HSC-T6 was divided into saline serum control group, blueberry serum at low, middle, high dose and Fu-Fang-Bie-Jia-Ruan-Gan tablet serum group, and then was respectively incubated at different dose of 10% blueberry serum, 10% Fu-Fang-Bie-Jia-Ruan-Gan tablet serum and 10% saline serum for 72 hours.Apoptosis of HSC-T6 was detected using flow cytometry with annexin V FITC/PI double staining. The expression of Bcl-2 and Bax in HSC-T6 were examined using immunocytochemistry and Western blotting, respectively. There was no significant difference for HSC-T6 Bax protein expression in the low, middle and high dose blueberry serum groups, compared with saline serum control group, respectively.In the high-dose blueberry serum group HSC-T6 early and total apoptosis rate increased significantly compared with the saline serum control group (5.55% ± 0.98% vs 2.53% ± 0.46%, 7.01% ± 1.05% vs 2.96% ± 0.81%, both Pblueberry serum group showed no significant difference with the saline serum control group. Blueberry can induce HSC-T6 apoptosis by down-regulating Bcl-2 expression and decreasing the ratio of Bcl-2/Bax in HSC-T6 cells, so it may have potential interference effects on hepatic fibrosis.

    Full Text Available Objective: The aim of the study was to analyse KIR/HLA profiles and to create the predictive probabilities for the selection of the most suitable Hematopoietic Stem Cell Transplantation (HSCT donor. Materials and Methods: The study was conducted on 92 patients with malignant hematological deseases and 181 their first degree relatives, from the region of Vojvodina. HLA and KIR genotyping was performed by polymerase chain reaction-sequence specific primers (PCR-SSP assay. The analysis included the degree of HLA matching between transplant pairs, number of missing ligands for inhibitory KIR genes, existence of GvH / HvG ligand-ligand mismatches (specific for C1, C2 or Bw4 ligands and distribution of C1/C1, C1/C2, C2/C2 HLA ligand groups in patients. Results: There was no significant differences in HLA frequencies between donors and recipients as analyzed by pairwise comparison, the probability of finding HLA identical donor is only 0.154, the probability of finding the donor with ≥ 1 KIR-ligand mismatch is 0.939, the probability of finding the donor with KIR-ligand mismatch for the KIR 2DL1 gene is 0.298, probability of having favorable C1/C1 and C2/C2 HLA ligand groups is 0.565. Conclusion: The results of our study could be used as a basis for the HSCT outcome prediction representing a powerful tool for choosing the most suitable donor.

  1. IMMUNE STATE IN PATIENTS WITH HEMATOLOGICAL MALIGNANCIES AT LATE TERMS AFTER AUTOLOGOUS HEMATOPOIETIC STEM CELL TRANSPLANTATION

    Directory of Open Access Journals (Sweden)

    N. V. Minaeva

    2012-01-01

    Full Text Available Abstract. Autologous hematopoietic stem cell transplantation (auto-HSCT is one of the most effective methods for treatment of patients with various forms of hemoblastoses, both in adults and children. However, high-dose chemotherapy protocols used in this procedure are characterized by pronounced myeloand immunotoxicity. Appropriate data concerning immune state at long terms after high-dose chemotherapy and auto-HSCT are sparse and controversial, and there is no consensus on time dynamics of immune system reconstitution. The aim of this study was a comprehensive evaluation of immunity in recipients of auto-HSCT at longer terms. Clinical and immunological testing was performed in ninety-eight patients with hematological malignancies before starting a high-dose chemotherapy, and at late post-transplant period. The state of cellular immunity was assessed as expression of surface CD3+, CD4+, CD8+, CD16+, CD19+ lymphocyte antigens. Humoral immunity was evaluated by serum IgG, IgA, and IgM levels. The studies have revealed disorders of cellular and humoral immunity, as well as nonspecific immune resistance factors in recipients of autologous hematopoietic stem cells at late terms post-transplant. Immune reconstitution in patients receiving highdose consolidation treatment followed by auto-HSCT takes longer time than in patients who did not receive autologous hematopoietic stem cells. Severity of these disturbances and immune reconstitution rates depend on the type of conditioning regimen, and the source of haematopoietic stem cells used for transplantation.

  2. Aircraft Emission Inventories Projected in Year 2015 for a High Speed Civil Transport (HSCT) Universal Airline Network. Final report

    This report describes the development of a three-dimensional database of aircraft fuel burn and emissions (fuel burned, NOx, CO, and hydrocarbons) from projected fleets of high speed civil transports (HSCT`s) on a universal airline network. Inventories for 500 and 1000 HSCT fleets, as well as the concurrent subsonic fleets, were calculated. The objective of this work was to evaluate the changes in geographical distribution of the HSCT emissions as the fleet size grew from 500 to 1000 HSCT`s. For this work, a new expanded HSCT network was used and flights projected using a market penetration analysis rather than assuming equal penetration as was done in the earlier studies. Emission inventories on this network were calculated for both Mach 2.0 and Mach 2.4 HSCT fleets with NOx cruise emission indices of approximately 5 and 15 grams NOx/kg fuel. These emissions inventories are available for use by atmospheric scientists conducting the Atmospheric Effects of Stratospheric Aircraft (AESA) modeling studies. Fuel burned and emissions of nitrogen oxides (NOx as NO2), carbon monoxide, and hydrocarbons have been calculated on a 1 degree latitude x 1 degree longitude x 1 kilometer attitude grid and delivered to NASA as electronic files.

    Full Text Available Abstract Background Neurotoxicity is a recognized complication of cyclosporine A (CSA treatment. The incidence of severe CSA-related neurological complications following hematopoietic stem cell transplantation (HSCT is 4-11%. Methods We describe 6 cases of CSA related neurotoxicity out of 67 matched related HSCT performed in paediatric Middle East patients affected by haemoglobinopaties (5 beta thalassemia major, 1 sickle cell disease-SCD. Conditioning regimen consisted of iv busulphan, cyclophosphamide and graft-versus-host-disease (GvHD prophylaxis with CSA, methylprednisolone, methotrexate and ATG. Results All 6 patients presented prodromes such as arterial hypertension, headache, visual disturbances and vomiting, one to two days before overt CSA neurotoxicity. CSA neurotoxicity consisted of generalized seizures, signs of endocranial hypertension and visual disturbances at a median day of onset of 11 days after HSCT (range +1 to +40. Brain magnetic resonance imaging (MRI performed in all subjects showed reversible leukoencephalopathy predominantly in the posterior regions of the brain (PRES in 5/6 patients. EEG performed in 5/6 patients was always abnormal. Neurotoxicity was not explainable by high CSA blood levels, as all patients had CSA in the therapeutic range with a median of 178 ng/ml (range 69-250. CSA was promptly stopped and switched to tacrolimus with disappearance of clinical and radiological findings. All patients are symptoms-free at a median follow up of 882 days (range 60-1065. Conclusions Our experience suggests that paediatric patients with haemoglobinopaties have a high incidence of CSA related neurological events with no correlation between serum CSA levels and neurotoxicity. Prognosis is good following CSA removal. Specific prodromes such as arterial hypertension, headache or visual disturbances occurring in the early post-transplant period should be carefully evaluated with electrophysiological and MRI-based imaging in

    Ocular complications occur after transplant in 60–90% of chronic graft versus host disease (GVHD) patients and significantly impair vision-related quality of life. Ocular surface inflammation and dry eye disease (DED) are the most common manifestations of ocular GVHD (oGVHD). oGVHD can be viewed as an excellent pre- clinical model that can be studied to understand the immune pathogenesis of this common and debilitating disease. A limitation of this is that only a few experimental models mimic the ocular complications following HSCT and have focused on the acute GVHD process. To address this issue, we used a pre-clinical animal model developed by our group where ocular involvement was preceded by systemic GVHD to gain insight regarding the contributing immune mechanisms. Employing this "MUD" model enabled the development of a clinical scoring criterion, which readily identified different degrees of ocular pathology at both the ocular surface and adnexa dependent on the level of conditioning prior to HSCT. As far as we are aware we report that for the first time these clinical and immune responses occur not only on the ocular surface, but also heavily involve the lid margin region. In total, the present study reports a pre-clinical scoring model that can be applied to animal models as investigators look to further explore GVHD's immunologic effects at the level of the ocular surface and eyelid adnexa compartments. We speculate that future studies will use this clinical scoring index in combination with what is recognized histologically and correlated with serum biomarkers being identified in chronic/ocular GVHD.

    Bone marrow transplantation following cytoreduction with total body irradiation and cyclophosphamide has previously been shown to be of value in treating refractory leukemias. Major problems, however, have been fatal interstitial pneumonitis and leukemic relapse. In an attempt to minimize these problems, we initiated a new hyperfractionated regimen for total body irradiation, with partial lung sparing. From May 1979 through July 1980, we treated 48 leukemia patients according to this regimen, varying in age from 1.5 to 42 years old (mean age: 18 y). Analysis in September 1980, with follow-up from 2 to 16 months, showed that we have a significantly reduced incidence of interstitial pneumonitis compared with single dose (1000 rad) irradiation (33 vs 70%), as well as decreased deaths attributable to interstitial pneumonitis (23 vs 50%). This is reflected in the survival curves, with loss of the early drop in survival previously observed with single dose irradiation. One year actuarial survival was 65% for acute lymphocytic leukemia (n = 16) and 72% for actue non-lymphocytic leukemia (n = 29). This compares with only 17% for acute non-lymphocytic leukemia patients (n = 12) on our previous single dose regimen. Age was also found to be an important parameter for both survival and interstitial pneumonitis

    Objective: To determine the conditioning regimen suitable for mice allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: Twelve BALB/c mice were randomly divided into 2 equal groups to undergo X-ray irradiation by linear accelerator at the dose of 7.0 Gy (pure X-ray group) or 60 Co source irradiation at the dose of 7.0 Gy (pure γ-ray group). Thirty mice were randomly divided into 2 equal groups to undergo X-ray irradiation and then infusion of bone marrow from donor mice via caudal vein (X-ray + transplantation group) or γ-ray and then infusion of bone marrow via caudal vein (γ-ray + transplantation group). 3, 5, 7, 10, 15, 20, and 30 d later peripheral blood samples were collected to calculate the number of white blood cells (WBCs) and detect the chimeric rates of lymphocytes by flow cytometry. 5, 10, and 20 d after irradiation 15 mice were killed with their lung, liver, small intestine, spleen, and femurs taken out to undergo pathological examination. Results: The survival rates during the period 5-15 days of the γ-ray + transplantation group were all significantly higher than those of the X-ray + transplantation group. The pathological changes of organs of the X-ray + transplantation group were all more severe than those of the γ-ray + transplantation group. Since the fifth day after transplantation cells originating from the donor began to appear in the peripheral blood. The chimeric rate of the γ-ray + transplantation group 10 days after transplantation was (95.53± 2.57) %. The chimeric rates 5, 10, and 20 days after transplantation of the γ-ray + transplantation group were all significantly higher than those of the X-ray + transplantation group (t=15.263, 3.256, P<0.05). The WBC count of both irradiation groups decreased to the lowest level 5 d later and began to increase 10 days after transplantation and the WBC counts of the γ-ray + transplantation group 10 and 20 days after transplantation were both significantly higher than

The prophylactic use of intravenous once-daily ceftriaxone in patients receiving outpatient based HSCT is safe and may be particularly effective in patients receiving autologous HSCT. Further studies are warranted to study the impact of this Prophylactic strategy in an outpatient based HSCT program.

    We confirm that successful KT is associated with BC modifications; which can be detected very early post KT. These very early changes are strongly associated with energy, protein intake and physical activity level pre KT. Management of post KT weight gain should be anticipated with a special care on nutritional intake and physical activity in patients waiting kidney transplantation.

    Many pediatric oncology patients undergoing hematopoietic stem cell transplantation (HSCT) require nutritional support (NS) because of their inability to consume adequate caloric intake enough calories orally. Although NS can be provided either enteraly (EN) or parenteraly (PN), EN is the preferred method of NS as long as if the gastrointestinal tract is functioning. In this qualitative study, we determined the type of NS preferences and the reservations of caregivers of pediatric HSCT patients undergoing hematopoietic stem cell transplantation (HSCT) as well as those of health care (HC) providers working on the HSCT unit. A survey was developed and completed anonymously by HC providers and caregivers. The hypothesis was that HC providers and caregivers would prefer PN because it is convenient to use in patients who already have a central line in place. Most caregivers preferred PN to EN, while most HC providers preferred EN to PN. The barrier between EN initiation and caregivers' approval was the caregivers' perception that EN was invasive and painful, most common obstacle for initiation of EN among caregivers was that it hurts/is invasive, while the barrier with HC providers was vomiting and/abdominal pain associated with EN. If caregivers were better educated about NS and the advantages/disadvantages of the different forms of NS, their preferences may change. There have been policy changes at St. Jude have been implemented since this study, and an outpatient dietitian now provides education to caregivers about NS during the pre-evaluation for HSCT. © 2015 Wiley Periodicals, Inc.

    Voriconazole is a commonly used antifungal medication in allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients. In solid organ transplantation, voriconazole use has been associated with the development of cutaneous squamous cell carcinoma (SCC). We sought to determine if voriconazole use was associated with SCC in patients undergoing allo-HSCT. We retrospectively reviewed consecutive adult patients who underwent allo-HSCT at Mayo Clinic from January 2007 through July 2012. Multivariable Cox models were created to assess the relationship of SCC with two time-dependent voriconazole exposure variables: (i) history of voriconazole exposure (yes/no), and (ii) cumulative days of voriconazole use. In our cohort of 381 allo-HSCT patients, SCC developed in 26 of 312 patients exposed to voriconazole (25 post-voriconazole) and in 1 of 69 patients who received alternative antifungal agent(s). Cumulative incidence of SCC was estimated to be 19% at 5 years post allo-transplant. Cumulative days of voriconazole use was found to be a risk factor for SCC, and this relationship persisted in a multivariable model using previously identified risk factors as covariates (hazard ratio 1.859 for each 180 days of use, P voriconazole use as a risk factor for SCC development following allo-HSCT, and may help guide appropriate antifungal use in this patient population. © 2015 John Wiley & Sons A/S.

    Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only treatment with curative potential for certain aggressive hematopoietic malignancies. Its success is limited by acute graft-versus-host disease (GVHD), a life-threatening complication that occurs when allo-reactive donor T cells attack recipient organs. There is growing evidence that microbes and innate pattern-recognition receptors (PRRs) such as toll-like receptors (TLR) and nod-like receptors (NLR) are critically involved in the pathogenesis of acute GVHD. Currently, a widely accepted model postulates that intensive chemotherapy and/or total-body irradiation during pre-transplant conditioning results in tissue damage and a loss of epithelial barrier function. Subsequent translocation of bacterial components as well as release of endogenous danger molecules stimulate PRRs of host antigen-presenting cells to trigger the production of pro-inflammatory cytokines (cytokine storm) that modulate T cell allo-reactivity against host tissues, but eventually also the beneficial graft-versus-leukemia (GVL) effect. Given the limitations of existing immunosuppressive therapies, a better understanding of the molecular mechanisms that govern GVHD versus GVL is urgently needed. This may ultimately allow to design modulators, which protect from GvHD but preserve donor T-cell attack on hematologic malignancies. Here, we will briefly summarize current knowledge about the role of innate immunity in the pathogenesis of GVHD and GVL following allo-HSCT.

    To demonstrate safety and efficacy of haploidentical bone marrow transplantation with non-myeloablative conditioning and high-dose post-transplant cyclophosphamide in adult patients with leukaemia or lymphoma. Human leukocyte antigen haploidentical bone marrow transplantation is a treatment option in patients with haematological malignancies who have no available human leukocyte antigen-matched donor but is limited by conditioning regimen toxicity, graft failure, relapse and graft-versus-host disease (GvHD). Twelve patients, median age of 51 years, underwent transplantation with T cell replete bone marrow from a haplotype-matched relative. The conditioning regimen consisted of cyclophosphamide, fludarabine and low-dose total body irradiation. Post-transplant immunosuppression consisted of a single dose of cyclophosphamide 50 mg/kg on day 3, followed by oral tacrolimus and mycophenolate mofetil. Outcomes reported are overall survival, engraftment and chimerism, toxicity, and clinical outcome. All patients had neutrophil recovery (median 14.5 days), and 11 of 12 had platelet engraftment (median 17 days). Two patients had autologous reconstitution. Seven of nine assessable patients had complete donor chimerism. Four patients had grades II-III GvHD, and none had grade IV GvHD. Four patients developed limited stage chronic GvHD. Five patients with acute myeloid leukaemia relapsed. Two patients died of nonrelapse causes, both from other malignancies, and five patients remain alive and relapse free. Median overall survival was 324 days (range 88-1163). This regimen is feasible and well tolerated in older patients with high-risk leukaemia or lymphoma, with minimal short-term toxicity and low rates of GvHD. The proportion of disease-free survivors indicates a graft-versus-malignancy effect is present in survivors. © 2012 The Authors; Internal Medicine Journal © 2012 Royal Australasian College of Physicians.

    The transplantation of cells, tissues, and organs has been recognised by WHO as an important medical task for its member states; however, information about how to best organise transplantation is scarce. We aimed to document the activity worldwide from the beginning of transplantation and search for region adapted indications and associations between transplant rates and macroeconomics. Between Jan 1, 2006, and Dec 31, 2014, the Worldwide Network for Blood and Marrow Transplantation collected data for the evolution of haemopoietic stem-cell transplantation (HSCT) activity and volunteer donors in the 194 WHO member states. 953,651 HSCTs (553,350 [58%] autologous and 400,301 [42%] allogeneic) were reported by 1516 transplant centres from 75 countries. No transplants were done in countries with fewer than 300,000 inhabitants, a surface area less than 700 km(2), and a gross national income per person of US$1260 or lower. Use of HSCT increased from the first transplant in 1957 to almost 10,000 by 1985. We recorded a cumulative total of about 100,000 transplants by 1995, and an estimated 1 million by December, 2012. Unrelated donor registries contributed 22·3 million typed volunteer donors and 645,646 cord blood products by 2012. Numbers of allogeneic HSCTs increased in the past 35 years with no signs of saturation (R(2)=0·989). Transplant rates were higher in countries with more resources, more transplant teams, and an unrelated donor infrastructure. Our findings show achievements and high unmet needs and give guidance for decisions; to grant access for patients, to provide a donor infrastructure, and to limit overuse by defining risk and region adapted indications for HSCT as an efficient and cost-effective approach for life-threatening, potentially curable diseases.

    To analyze the causes of arterial bleeding after living donor liver transplantation (LDLT) and to evaluate the efficacy of transcatheter arterial embolization (TAE). Forty-two sessions of conventional arteriography were performed in 32 of the 195 patients who underwent LDLT during the past 2 years. This was done in search of bleeding foci of arterial origin. TAE was performed with microcoils or gelatin sponge particles. The causes of arterial bleeding, the technical and clinical success rates of TAE and the complications were retrospectively evaluated. Forty-two bleeding foci of arterial origin were identified on 30 sessions of arteriography in 21 patients. The most common cause of bleeding was percutaneous procedures in 40% of the patients (17 of the 42 bleeding foci) followed by surgical procedures in 36% (15/42). The overall technical and clinical success rates of TAE were 21 (70%) and 20 (67%) of the 30 sessions, respectively. The overall technical success rate of TAE for the treatment of bleeding from the hepatic resection margin, hepatic artery anastomotic site and hepaticojejunostomy was only 18% (2/11), whereas for the treatment of bleeding in the other locations the technical and clinical success rates of TAE were 100% and 95%, respectively. No procedure-related major complications occurred. In the case of arterial bleeding after LDLT, percutaneous procedure-related hemorrhages were as common as surgery-related hemorrhages. There were technical difficulties in using TAE for the treatment of hepatic arterial bleeding. However, in the other locations, TAE seems to be safe and effective for the control of arterial bleeding in LDLT recipients

    Full Text Available In mammals, damage to sensory receptor cells (hair cells of the inner ear results in permanent sensorineural hearing loss. Here, we investigated whether postnatal mouse inner ear progenitor/stem cells (mIESCs are viable after transplantation into the basal turns of neomycin-injured guinea pig cochleas. We also examined the effects of mIESC transplantation on auditory functions. Eight adult female Cavia porcellus guinea pigs (250-350g were deafened by intratympanic neomycin delivery. After 7 days, the animals were randomly divided in two groups. The study group (n=4 received transplantation of LacZ-positive mIESCs in culture medium into the scala tympani. The control group (n=4 received culture medium only. At 2 weeks after transplantation, functional analyses were performed by auditory brainstem response measurement, and the animals were sacrificed. The presence of mIESCs was evaluated by immunohistochemistry of sections of the cochlea from the study group. Non-parametric tests were used for statistical analysis of the data. Intratympanic neomycin delivery damaged hair cells and increased auditory thresholds prior to cell transplantation. There were no significant differences between auditory brainstem thresholds before and after transplantation in individual guinea pigs. Some mIESCs were observed in all scalae of the basal turns of the injured cochleas, and a proportion of these cells expressed the hair cell marker myosin VIIa. Some transplanted mIESCs engrafted in the cochlear basilar membrane. Our study demonstrates that transplanted cells survived and engrafted in the organ of Corti after cochleostomy.

    Full Text Available The article focuses on aspects of T. gondii reactivation/reinfection in patients undergoing allogeneic hematopoietic stem cell transplantation (alloHSCT. We have observed 297 patients who received conditioning therapy and allogeneic grafts due to different oncohematological or lymphoproliferative diseases (1 to 60 years old, at a mediane of 19 years. Conditioning regimens were either myeloablative (35%, or non-myeloablative (65%. DNA diagnostics of T. gondii was performed on a regular basis at 0 to 6 months post-HSCT. IgG and IgM antibodies against T. gondii were determined in 78 patients before HSCT, as well as in their donors. T. gondii DNA post-transplant proved to be positive in 13% of blood specimens, 9% of cerebrospinal liquor samples, 11% of bronchoalveolar cell lavages, and in 5% of urine sediments. In adolescent patients (10 to 14 years old, an increased prevalence of T. gondii was found in patients who received myeloablative treatment (p = 0.01. When assessing posttransplant dynamics of T. gondii, we have revealed distinct increase in the pathogen excretion within 1st month after HSCT (p = 0.03. Finally, initial presence of IgG antibodies against T. gondii in the patients was associated with lower incidence of the pathogen reactivation post-transplant.

    An 8-year-old girl with Chediak-Higashi syndrome (CHS) had pulmonary complications after hematopoietic stem cell transplantation (HSCT) for hemophagocytic lymphohistiocytosis (HLH) and eventually underwent single living-donor lobar lung transplantation (LDLLT). Electron micrographic findings showed vagus nerve tissue in extracted lung having granular inclusions, which are pathognomonic for CHS. Because her mother was the donor for both hematopoietic stem cell and lung transplantations, she was weaned from immunosuppression and is doing well 3 years after lung transplantation. Furthermore, an induced pluripotent stem (iPS) cell line was established from her skin fibroblasts for investigation and potential future treatment for CHS.

    Purpose. The primary objective of the present study was to identify the kinetics and origin of ocular infiltrating T cells in a preclinical model of graft-versus-host disease (GVHD) that induces eye tissue damage. Methods. Graft-versus-host disease was induced using an major histocompatibility complex (MHC)-matched, minor histocompatibility-mismatched hematopoietic stem cell transplant (HSCT) model. This approach, which utilized congenic and EGFP-labeled donor populations, mimics a matched, clinically unrelated donor (MUD) cell transplant. Systemic and ocular GVHD were assessed at varying time points using clinical examination, intravital microscopy, immune phenotype via flow cytometric analyses, and immunohistochemical staining. Results. Following transplant, we observed characteristic changes in GVHD-associated immune phenotype as well as clinical signs present in recipients post transplant. Notably, the kinetics of the systemic changes and the ocular damage paralleled what is observed clinically, including damage to the cornea as well as the conjunctiva and lacrimal gland. Importantly, the infiltrate contained predominantly donor CD4 as well as CD8 T cells with an activated phenotype and macrophages together with effector cytokines consistent with the presence of a TH1 alloreactive population. Conclusions. Overall, the findings here unequivocally demonstrated that donor T cells compose part of the corneal and ocular adnexa infiltrate in animals undergoing ocular GVHD. In total, the results describe a novel and promising preclinical model characterized by both systemic and ocular changes as detected in significant numbers of patients undergoing GVHD following allo-HSCT, which can help facilitate dissecting the underlying immune mechanisms leading to damage associated with ocular GVHD.

    Allogeneic hematopoietic stem-cell transplantation (HSCT) is potentially curative for acute leukemia (AL), but carries considerable risk. Machine learning algorithms, which are part of the data mining (DM) approach, may serve for transplantation-related mortality risk prediction. This work is a retrospective DM study on a cohort of 28,236 adult HSCT recipients from the AL registry of the European Group for Blood and Marrow Transplantation. The primary objective was prediction of overall mortality (OM) at 100 days after HSCT. Secondary objectives were estimation of nonrelapse mortality, leukemia-free survival, and overall survival at 2 years. Donor, recipient, and procedural characteristics were analyzed. The alternating decision tree machine learning algorithm was applied for model development on 70% of the data set and validated on the remaining data. OM prevalence at day 100 was 13.9% (n=3,936). Of the 20 variables considered, 10 were selected by the model for OM prediction, and several interactions were discovered. By using a logistic transformation function, the crude score was transformed into individual probabilities for 100-day OM (range, 3% to 68%). The model's discrimination for the primary objective performed better than the European Group for Blood and Marrow Transplantation score (area under the receiver operating characteristics curve, 0.701 v 0.646; Prisk evaluation of patients with AL before HSCT, and is available online (http://bioinfo.lnx.biu.ac.il/∼bondi/web1.html). It is presented as a continuous probabilistic score for the prediction of day 100 OM, extending prediction to 2 years. The DM method has proved useful for clinical prediction in HSCT. © 2015 by American Society of Clinical Oncology.

    Disease or treatment oriented registries form an integral part of modern medicine. They complement industry driven, corporate group sponsored and institutional research and are, together with prospective randomised trials cornerstones of modern evidence based medicine. Focus has been on rapid collection, analysis and dissemination of information on rare procedures with stress on patient outcome. In complex expensive procedures, such as hematopoietic stem cell transplants (HSCT), novel structures are required to catch outcome at team or national level. The annual activity survey of the European Group for Blood and Marrow Transplants EBMT forms such an instrument. Since 1990, EBMT has been collecting, on an annual basis, numbers of HSCT from the preceding year according to indication, donor type and stem cell source. The survey covers all European countries. In 1990, 143 teams reported 4,234 HSCT; in the year 2000, 619 teams reported 19,136 HSCT (33% allogeneic, 67% autologous). This information, which covers over 90% of all HSCT performed in Europe and is based on 132,963 HSCT (33% allogeneic, 67% autologous), gives a clear overview of current status and ongoing trends. It shows the general increase in HSCT from 1990 to 2000 with few exceptions, such as autologous HSCT for breast cancer and allogeneic HSCT for chronic myeloid leukemia. It illustrates the shift in technology from bone marrow as stem cell source in 1990 (100%) to peripheral blood in 2000 (96% of autologous, 53% of allogeneic HSCT). Supplemented by population data and economic factors (Gross national Product, Health Care Expenditures, Health Care systems) of the individual countries it allows comparison of transplant rates (Number of transplants per 10 million inhabitants), team densities (Number of transplant teams per 10 million inhabitants) and trends between countries. It permits quantification of the impact of economics and health care systems and provides a basis for quality control and allows

    Isolation in a germ-free unit is a stressful experience for pediatric patients undergoing hematopoietic stem cell transplantation (HSCT). To reduce the psychological distress of such children, a Web-based telecommunications system was developed. The authors developed a telecommunication system that linked a laminar air flow (LAF) room that had a high efficiency particulate air filter with the hospital school/patients' homes via the Internet. Fifteen children isolated in the LAF room for allogeneic HSCT were enrolled in this study. The present study evaluated whether the system was feasible for the patients during the acute phase of HSCT. In 10 patients, the proportion of days when they telecommunicated with teachers and/or other patients in the hospital school was 64.6 ± 32.3%. The telecommunication with the hospital school facilitated the continuation of school study under teachers' guidance, reducing the problem of lost schooling. In 13 patients, the proportion of days when they telecommunicated with their homes was 68.0 ± 34.8%. Ten of them frequently telecommunicated with their family members (especially siblings), and three patients called out to their pets at home. The incidence of telecommunication on the days when the patients had HSCT-related symptoms including vomiting did not differ from that of telecommunication on the days when no symptoms were evident. A telecommunication system linked to a hospital school and/or the patients' homes is feasible for children undergoing HSCT, and may improve their health-related quality of life. A larger, prospective study is required to evaluate whether the telecommunication system can reduce HSCT-associated psychological and psychiatric symptoms. © 2011 The Authors.

    Using the data from the GETMON ("Grupo Español de Trasplante de Medula Osea en Niños") we carried out a retrospective analysis of the results of allogeneic bone marrow transplantation (alloBMT) compared to autologous bone marrow transplantation (ABMT) in 113 paediatric patients with acute lymphoblastic leukaemia (ALL) in second remission. Transplants were performed by the following centers, from April 1983 to December 1991: H. Vall d'Hebrón and H. Sant Pau from Barcelona, H. Ramón y Cajal and H. Niño Jesús from Madrid and H. Marqués de Valdecilla from Santander. The study included 113 patients between the ages of two and 16 years with ALL in second remission at marrow transplant. Fifty-six underwent alloBMT and 57 ABMT. Both groups were homogeneous with respect to age, sex, immunophenotype, duration of first remission, risk at diagnosis, percentage of early and late relapses, percentage with marrow or extramedullary relapse prior to transplant, time interval from attainment of second remission to transplant, and conditioning regimens applied for marrow transplant, with predominance of chemoradiotherapy in both. Haematologic recovery was observed to be faster in alloBMT than in ABMT. A granulocyte count > 0.5 x 10(9)/l was reached in alloBMT patients in a median of 19 days and in ABMT patients in a median of 25 days (p 30 months) 61.1 +/- 13.8%, than those who had presented an early relapse (< 30 months) 18.3 +/- 6.5% (p < 0.005). Probability of relapse was significantly greater in ABMT (70%) compared to alloBMT (46%) (p < 0.025). Transplant offers a better DFS in extramedullary relapses compared to isolated or combined bone marrow relapses: 71.4 +/- 17.1% with alloBMT and 38.1 +/- 14.7% with ABMT (p = NS). In our experience we observed a better DFS with alloBMT compared with ABMT, overcoat in early relapses, but without significant difference. A higher relapse rate in ABMT group is partially compensated by more early deaths in alloBMT offers a few survival

    Cytogenetics has an important impact on the prognosis of patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) for AML or MDS. However, it is unclear whether currently accepted cytogenetic risk groups, which were established for patients treated mostly with standard therapy, are optimally discriminating for patients undergoing HSCT. Also, the impact of cytogenetics in the growing population of patients with therapy-related disease has not been completely elucidated. In this study, we retrospectively analyzed data on 556 patients with AML or MDS transplanted at our institution. We examined, in multivariate analyses, the contribution of cytogenetics to survival, relapse, and non-relapse mortality (NRM) for the 476 patients with de novo disease. We used these results to establish an optimal cytogenetic grouping scheme. We then applied this grouping scheme to the 80 patients with therapy-related disease. Our proposed three-group cytogenetic classification outperformed the established grouping schemes for both de novo and therapy-related disease. When classified by this new scheme, cytogenetics was the strongest prognostic factor for overall survival in our cohort, through its impact on the risk of relapse (and not on NRM). After accounting for cytogenetics, patients with therapy-related AML or MDS had an equivalent outcome to those with de novo disease. This study demonstrates the impact of cytogenetics on the risk of relapse and death for patients with both de novo and therapy-related disease undergoing transplantation; it also emphasizes the necessity of using cytogenetics to stratify patients entering clinical trials, and provides a system for doing so, which can be validated in a multi-institutional database.

    Data on 68 146 hematopoietic stem cell transplants (HSCTs) (53% autologous and 47% allogeneic) gathered by 1566 teams from 77 countries and reported through their regional transplant organizations were analyzed by main indication, donor type and stem cell source for the year 2012. With transplant rates ranging from 0.1 to 1001 per 10 million inhabitants, more HSCTs were registered from unrelated 16 433 donors than related 15 493 donors. Grafts were collected from peripheral blood (66%), bone marrow (24%; mainly non-malignant disorders) and cord blood (10%). Compared with 2006, an increase of 46% total (57% allogeneic and 38% autologous) was observed. Growth was due to an increase in reporting teams (18%) and median transplant activity/team (from 38 to 48 HSCTs/team). An increase of 167% was noted in mismatched/haploidentical family HSCT. A Strengths, Weaknesses, Opportunities, Threats (SWOT) analysis revealed the global perspective of WBMT to be its major strength and identified potential to be the key professional body for patients and authorities. The limited data collection remains its major weakness and threat. In conclusion, global HSCT grows over the years without plateauing (allogeneic>autologous) and at different rates in the four World Health Organization regions. Major increases were observed in allogeneic, haploidentical HSCT and, to a lesser extent, in cord blood transplantation.

    Full Text Available The introduction of peripheral stem cell (PSC and cord blood (CB as an alternative to bone marrow (BM recently has caused important changes on hematopoietic stem cell transplantation (HSCT practice. According to the CIBMTR data, there has been a significant decrease in the use of bone marrow and increase in the use of PSC and CB as the stem cell source for HSCT performed during 1997–2006 period for patients under the age of 20. On the other hand, the stem cell source in 70% of the HSCT procedures performed for patients over the age of 20 was PSC and the second most preferred stem cell source was bone marrow. CB usage is very limited for the adult population. Primary disease, stage, age, time and urgency of transplantation, HLA match between the patient and the donor, stem cell quantity, and the experience of the transplantation center are some of the associated factors for the selection of the appropriate stem cell source. Unfortunately, there is no prospective randomized study aimed to facilitate the selection of the correct source between CB, PSC, and BM. In this paper, we would like to emphasize the data on stem cell selection in light of the current knowledge for patient populations according to their age and primary disease.

    Passenger lymphocyte syndrome (PLS) presents as transient immune hemolysis due to anti-recipient ABO antibodies produced by donor B-lymphocytes accompanying minor or bidirectional ABO incompatible allogeneic hematopoietic stem cell transplantation (HSCT). We monitored both IgM and IgG type anti-recipient ABO antibodies in 18 consecutive HSCT recipients with hematological malignancies. Five of these patients (28%) developed transient immune hemolysis due to PLS after a median of 19 days post-HSCT. This response was associated with the detection of IgM and IgG anti-recipient ABO antibodies after a median of 16 and 22 days post-HSCT, respectively. All five patients subsequently developed acute graft-versus-host disease (GVHD) grades II-IV, and three died due to transplant-related mortality (TRM) within 1 year after HSCT, while in contrast, of the 13 patients without PLS, three (23%) developed grades II-IV acute GVHD (p ABO antibody may be an early predictor of acute GVHD and poor survival after minor or bidirectional ABO incompatible HSCT.

  12. Voriconazole-Induced Periostitis Mimicking Chronic Graft-versus-Host Disease after Allogeneic Stem Cell Transplantation

    Full Text Available Voriconazole is an established first-line agent for treatment of invasive fungal infections in patients undergoing allogeneic stem cell transplantation (ASCT. It is associated with the uncommon complication of periostitis. We report this complication in a 58-year-old female undergoing HSCT. She was treated with corticosteroids with minimal improvement. The symptoms related to periostitis can mimic chronic graft-versus-host disease in patients undergoing HSCT and clinicians should differentiate this from other diagnoses and promptly discontinue therapy.

  14. Graft-versus-Leukemia Effect Following Hematopoietic Stem Cell Transplantation for Leukemia

    Directory of Open Access Journals (Sweden)

    Anne M. Dickinson

    2017-06-01

    Full Text Available The success of hematopoietic stem cell transplantation (HSCT lies with the ability of the engrafting immune system to remove residual leukemia cells via a graft-versus-leukemia effect (GvL, caused either spontaneously post-HSCT or via donor lymphocyte infusion. GvL effects can also be initiated by allogenic mismatched natural killer cells, antigen-specific T cells, and activated dendritic cells of leukemic origin. The history and further application of this GvL effect and the main mechanisms will be discussed and reviewed in this chapter.

    Objective. This study was designed to observe the histocompatibility and long-term results of wigs after xenogeneic hair transplantation and to explore the possibility of industrial products in clinical application. Methods. The human hair and melted medical polypropylene were preceded into the follicular unit-like wigs according to the natural follicular unit by extrusion molding. 12 New Zealand rabbits were used as experimental animals for wigs transplantation. The histocompatibility of polypropylene and human hair was observed by H&E staining and scanning electron microscope. The loss rate of wigs was calculated to evaluate the long-term result after transplantation. Results. Mild infiltration by inflammatory cells around the polypropylene and human hair were seen during the early period after transplantation, accompanied with local epithelial cell proliferation. The inflammatory cells were decreased after 30 days with increased collagen fibers around the polypropylene and human hair. The follicular unit-like wigs maintained a good histocompatibility in one year. The degradation of hair was not significant. The loss rate of wigs was 4.1 ± 4.0% in one year. The appearance of hair was satisfactory. Conclusions. We successfully developed a follicular unit-like wigs, which were made of xenogeneic human hair with medical polypropylene, showing a good histocompatibility, a low loss rate, and satisfactory appearance in a year after transplantation. The follicular unit-like wigs may have prospective industrial products in clinical application.

    To analyze the treatment outcome of a consecutive series of 100 leukemia patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT). The clinical data of leukemia patients received allo-HSCT were analyzed retrospectively, the therapeutic efficacy was summarized. 100 evaluable cases of leukemia included 47 cases of AML, 33 cases of ALL, 2 cases of AL (biphenotypic), 16 CML and 2 CMML. Before transplantation, 76 cases were in first complete remission, 9 cases in second or greater complete remission and 15 cases in non-remission or relapse. All the patients received peripheral blood hematopoietic stem cell transplantation (PBHSCT). The conditioning regimen of human leukocyte antigen (HLA)-matched allo-HSCT group was modified BuCy, but in HLA-mismatched group Fludarabine and anti-human thymocyte globulin (ATG) was added. CsA+MTX regimen was used for prophylaxis of graft-versus-host disease (GVHD) in HLA-identical allo-HSCT, while additional MMF was added in HLA-mismatched group. The average time of follow-up was 13 months. At the last follow-up, 66.0% (66/100) patients survived, 53.0% (53/100) patients survived without leukemia, 28.0% (28/100) patients relapsed and 34.0% (34/100) patients died, 44.1% patients of them died from infectious pulmonary complications. During transplantation, 65.0% of the patients were suffered from lung infection. The overall survival (OS) and disease-free survival (DFS) of all cases was 60.9% and 48.8%, respectively. The recurrence rate was significantly higher in non-remission (66.7%) than in CR (21.2%) patients (P < 0.05). The cumulative incidence of GVHD in HLA-mismatched transplantation was 60.8%, which was significantly higher than that of HLA-matched transplantation (38.8%) (P < 0.05). Allo-HSCT can cure a significant proportion of leukemia patients, especially for those in CR status. Since the incidence of infectious pulmonary complications after allo-HSCT is still high, much more attention should be paid to it

    Since the early beginnings, in the 1950s, hematopoietic stem cell transplantation (HSCT) has become an established curative treatment for an increasing number of patients with life-threatening hematological, oncological, hereditary, and immunological diseases. This has become possible due to worldwide efforts of preclinical and clinical research focusing on issues of transplant immunology, reduction of transplant-associated morbidity, and mortality and efficient malignant disease eradication. The latter has been accomplished by potent graft-versus-leukemia (GvL) effector cells contained in the stem cell graft. Exciting insights into the genetics of the human leukocyte antigen (HLA) system allowed improved donor selection, including HLA-identical related and unrelated donors. Besides bone marrow, other stem cell sources like granulocyte-colony stimulating-mobilized peripheral blood stem cells and cord blood stem cells have been established in clinical routine. Use of reduced-intensity or non-myeloablative conditioning regimens has been associated with a marked reduction of non-hematological toxicities and eventually, non-relapse mortality allowing older patients and individuals with comorbidities to undergo allogeneic HSCT and to benefit from GvL or antitumor effects. Whereas in the early years, malignant disease eradication by high-dose chemotherapy or radiotherapy was the ultimate goal; nowadays, allogeneic HSCT has been recognized as cellular immunotherapy relying prominently on immune mechanisms and to a lesser extent on non-specific direct cellular toxicity. This chapter will summarize the key milestones of HSCT and introduce current developments. PMID:27881982

  19. Application of Probabilistic Methods for the Determination of an Economically Robust HSCT Configuration

    1996-01-01

    This paper outlines an approach for the determination of economically viable robust design solutions using the High Speed Civil Transport (HSCT) as a case study. Furthermore, the paper states the advantages of a probability based aircraft design over the traditional point design approach. It also proposes a new methodology called Robust Design Simulation (RDS) which treats customer satisfaction as the ultimate design objective. RDS is based on a probabilistic approach to aerospace systems design, which views the chosen objective as a distribution function introduced by so called noise or uncertainty variables. Since the designer has no control over these variables, a variability distribution is defined for each one of them. The cumulative effect of all these distributions causes the overall variability of the objective function. For cases where the selected objective function depends heavily on these noise variables, it may be desirable to obtain a design solution that minimizes this dependence. The paper outlines a step by step approach on how to achieve such a solution for the HSCT case study and introduces an evaluation criterion which guarantees the highest customer satisfaction. This customer satisfaction is expressed by the probability of achieving objective function values less than a desired target value.

    Pancreas transplantation can be complicated by vascular thrombosis, stenosis, or anastomotic leak, complications that predispose to transplant pancreatectomy. The relative roles of noninvasive radiologic studies in such vascular complications have been correlated with angiographic or pathologic data. The results of 54 scintigraphic studies, 25 CT studies, 16 sonograms, and 23 color Doppler examinations have been correlated with those of 40 angiograms and 28 pathologic studies in a population of 185 recipients. CT (sensitivity, 100%; specificity, 75%; accuracy, 92%) and US (sensitivity, 88%; specificity, 80%; accuracy, 85%) were most helpful in noninvasive screening for vascular complications, while angiography remains nearly definite in the radiographic diagnosis of these problems

    Abstract: Infections with Hepatitis viruses B and C pose major problems both short and long term respectively after HSCT. The key to prevention for Hepatitis B disease remains vaccination for HBV-naïve patients and judicial use of anti-viral therapy in both pre- and post-transplant settings for HBV-infected patients. HBsAg positive grafts to HBV-naïve recipients result in transmission of the virus in about 50%. The newer anti-viral agents have enabled effective treatment of post-transplant patients who might be lamivudine-resistant or might develop so. Selecting a previously infected donor who has high titres of surface antibody for HBsAg positive patients gives the best chance for immunological clearance. The most challenging aspect of preventing HBV reactivation remains the duration of anti-viral therapy and timing of its withdrawal as most reactivations and often fatal ones occur after this period. Hepatitis C, on the other hand affects long-term survival with early onset of fibrosis and cirrhosis. Early effect of Hepatitis C virus on the immune system remains conjectural. The standard combination therapy seems to be effective, but data on this front remains sparse, as in the case of the use of newer antiviral agents. HSCT from HCV infected grafts result in more consistent transmission of the virus and pre-donation treatment of donors should be undertaken to render them non-viremic, if possible.  The current understanding and recommendations regarding prevention and management of these infections in HSCT recipients are discussed.

    Full Text Available Abstract Background The polyomaviruses WUPyV and KIPyV have been detected in various sample types including feces indicating pathogenicity in the gastrointestinal (GI system. However, quantitative viral load data from other simultaneously collected sample types are missing. As a consequence, primary replication in the GI system cannot be differentiated from swallowed virus from the respiratory tract. Here we present a retrospective quantitative longitudinal analysis in simultaneously harvested specimens from different organ sites of patients undergoing hematopoietic stem cell transplantation (HSCT. This allows the definition of sample types where deoxyribonucleic acid (DNA detection can be expected and, as a consequence, the identification of their primary replication site. Findings Viral DNA loads from 37 patients undergoing HSCT were quantified in respiratory tract secretions (RTS, stool and urine samples as well as in leukocytes (n = 449. Leukocyte-associated virus could not be found. WUPyV was found in feces, RTS and urine samples of an infant, while KIPyV was repeatedly detected in RTS and stool samples of 4 adult patients. RTS and stool samples were matched to determine the viral load difference showing a mean difference of 2.3 log copies/ml (p  Conclusions The data collected in this study suggest that virus detection in the GI tract results from swallowed virus from the respiratory tract (RT. We conclude that shedding from the RT should be ruled out before viral DNA detection in the feces can be correlated to GI symptoms.

    Full Text Available Background: Traditionally, lipids used in parenteral nutrition (PN are based on ω-6 fatty acid-rich vegetable oils, such as soybean oil, with potential adverse effects involving oxidative stress. Methods: We evaluated the antioxidant defense system in children, after hematopoietic stem cell transplantation (HSCT, who were randomized to use a lipid emulsion with fish oil or soybean oil. Blood samples at baseline, at 10 days, and at the end of the PN were taken to analyze plasma retinol, α-tocopherol, β-carotene, coenzyme Q9 and coenzyme Q10 levels, and catalase (CAT, glutathione reductase (GR, glutathione peroxidase (GPOX, and superoxide dismutase (SOD levels in lysed erythrocytes. Results: An increase in plasma α-tocopherol levels in the group of patients receiving the fish oil-containing emulsion (FO compared with the group receiving the soybean emulsion was observed at day 10 of PN. Concurrently, plasma α-tocopherol increased in the FO group and β-carotene decreased in both groups at day 10 compared with baseline levels, being more significant in the group receiving the FO emulsion. Conclusion: FO-containing emulsions in PN could improve the antioxidant profile by increasing levels of α-tocopherol in children after HSCT who are at higher risk of suffering oxidative stress and metabolic disorders.

    Transplant-associated thrombotic microangiopathy (TA-TMA) occurs frequently after hematopoietic stem cell transplantation (HSCT) and can lead to significant morbidity and mortality. There are no data addressing individual susceptibility to TA-TMA. We performed a hypothesis-driven analysis of 17 candidate genes known to play a role in complement activation as part of a prospective study of TMA in HSCT recipients. We examined the functional significance of gene variants by using gene expression profiling. Among 77 patients undergoing genetic testing, 34 had TMA. Sixty-five percent of patients with TMA had genetic variants in at least one gene compared with 9% of patients without TMA (P racial disparities previously reported in transplant recipients and may guide treatment strategies to improve outcomes. © 2016 by The American Society of Hematology.

    Epileptic seizures are frequent manifestations after hematopoietic stem cell transplantation (HSCT). In this retrospective single-center study we evaluated electroclinical features and analyzed etiologies and outcome of seizures after pediatric HSCT. Of 261 children transplanted between 2000 and 2010, we identified and analyzed data of 28 patients with seizures within a year from HSCT. Most frequent etiologies were posterior reversible encephalopathy syndrome (PRES, 14 patients) and central nervous system (CNS) infections (4 patients). Seizures were the presentation of the underlying complications in 22 patients. Sixteen episodes of status epilepticus were identified. Seizures secondary to PRES were usually longer and associated with non-convulsive signs. Early neuroimaging and EEG monitoring proved to be crucial to diagnose and treat seizures and their causes. No patients developed epilepsy suggesting that chronic antiepileptic therapy is not necessary in these patients. Overall survival was 32.3% over 5 years in patients with seizures and 45.8% in patients without seizures (poncological disease and cord blood stem cell transplantation. Seizures in transplanted children are a severe event and are associated with high morbidity and poor outcome. In particular, patients with non-oncological diseases and cord blood stem cell transplantation have to be considered at high risk of seizures. Moreover, this study underlines the importance of early recognition of non-convulsive clinical signs and of EEG monitoring for a prompt diagnosis and an appropriate management of seizures and their causes.

    Hastening posttransplantation immune reconstitution is a key challenge in human leukocyte antigen (HLA)-haploidentical hematopoietic stem-cell transplantation (HSCT). In experimental models of mismatched HSCT, T-regulatory cells (Tregs) when co-infused with conventional T cells (Tcons) favored posttransplantation immune reconstitution and prevented lethal graft-versus-host disease (GVHD). In the present study, we evaluated the impact of early infusion of Tregs, followed by Tcons, on GVHD prevention and immunologic reconstitution in 28 patients with high-risk hematologic malignancies who underwent HLA-haploidentical HSCT. We show for the first time in humans that adoptive transfer of Tregs prevented GVHD in the absence of any posttransplantation immunosuppression, promoted lymphoid reconstitution, improved immunity to opportunistic pathogens, and did not weaken the graft-versus-leukemia effect. This study provides evidence that Tregs are a conserved mechanism in humans.

    Full Text Available Hematopoietic stem cell transplantation (HSCT is becoming an effective therapeutic modality for a variety of diseases. Mesenchymal stem cells (MSCs can be used to enhance hematopoietic engraftment, accelerate lymphocyte recovery, reduce the risk of graft failure, prevent and treat graft-versus-host disease, and repair tissue damage in patients receiving HSCT. Till now, most MSCs for human clinical application have been derived from bone marrow. However, acquiring bone-marrow-derived MSCs involves an invasive procedure. Umbilical cord is rich with MSCs. Compared to bone-marrow-derived MSCs, umbilical cord-derived MSCs (UCMSCs are easier to obtain without harm to the donor and can proliferate faster. No severe adverse effects were noted in our previous clinical application of UCMSCs in HSCT. Accordingly, application of UCMSCs in humans appears to be feasible and safe. Further studies are warranted.

The role of HSCT in the treatment of AML was discussed by the authors and presented to the Brazilian Society of Bone Marrow Transplantation in a meeting to formulate and ratify the Brazilian Guidelines on HSCT. This consensus was based on a review of international publications and on the Brazilian experience in HSCT for the treatment of AML. The optimal treatment for AML in first complete remission (1CR has not been defined yet. There is consensus on the indication of allogeneic HSCT with myeloablative conditioning for patients who present high risk cytogenetic changes. Allogeneic HSCT is not indicated for low cytogenetic risk 1RC patients and, apparently, allogeneic and autologous HSCT and consolidation chemotherapy are similar for intermediate risk

    MDS/MPN (myelodysplastic syndrome/myeloproliferative neoplasm) overlap syndromes are myeloid malignancies for which allogeneic hematopoietic stem cell transplant (allo-HSCT) is potentially curative. We describe transplant outcomes of 43 patients - 35 with chronic myelomonocytic leukemia, CMML (of which 17 had blast transformation, BT) and eight with MDS/MPN-unclassifiable (MDS/MPN,U). At median follow-up of 21 months, overall survival (OS), cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) were 55%, 29%, and 25% respectively in CMML without BT and 47%, 40%, and 34% respectively in CMML with BT. Higher HSCT-comorbidity index (HSCT-CI >3 versus ≤3; p = 0.015) and splenomegaly (p = 0.006) predicted worse OS in CMML without BT. In CMML with BT, engraftment failure (p = 0.006) and higher HSCT-CI (p = 0.03) were associated with inferior OS, while HSCT within 1-year of diagnosis was associated with improved OS (p = 0.045). In MDS/MPN,U, at median follow-up of 15 months, OS, CIR, and NRM were 62%, 30%, and 14%, respectively.

    Metachromatic Leukodystrophy (MLD) is a rare, fatal demyelinating disorder with limited treatment options. Published outcomes after hematopoietic stem cell transplantation (HSCT) are scant and mixed. We report survival and function following HSCT for a large, single-center MLD cohort. Transplant-related data, survival and serial measures (brain MRI, nerve conduction velocity (NCV), neurologic and neuropsychology evaluations) were reviewed. When possible, parental interviews informed current neurologic status, quality-of-life, and adaptive functioning. Gross motor and expressive functions for late-infantile (LI-MLD) and juvenile (J-MLD) patients were described using previously reported, MLD-specific scales. Forty patients with confirmed MLD have undergone HSCT at our center. Twenty-one (53 %) survive at a median 12 years post-HSCT. Most deaths (n = 17) were treatment-related; two died from disease progression. Survival did not depend upon MLD subtype or symptom status at transplant. LI-MLD patients survive beyond reported life expectancy in untreated disease. Abnormal brain MRI and peripheral nerve conduction velocities (NCV) were common before HSCT. Following transplant, fewer patients experienced MRI progression compared to NCV deterioration. Sixteen LI-MLD and J-MLD survivors were evaluable for long-term gross motor and/or expressive language functioning using existing MLD clinical scoring systems. While most J-MLD patients regressed, the aggregate cohort demonstrated superior retention of function compared to published natural history. Seventeen LI-MLD, J-MLD and adult subtype (A-MLD) survivors were evaluable for long-term adaptive functioning, activities of daily living, and/or cognition. Relative cognitive sparing was observed despite overall global decline. Five sibling pairs (one LI-MLD and four J-MLD), in which at least one underwent transplant in our cohort, were evaluable. Within each familial dyad, survival or function was superior for the treated

    humans, and its association with cirrhosis makes the therapeutic approach still a challenge. Liver transplantation is the treatment of choice for cirrhotic patients with unresectable early hepatocellular carcinoma AIM: To evaluate the post-transplant outcome of a cohort of 15 cirrhotic patients with preoperative diagnosis of unresectable early hepatocellular carcinoma according the Milan criteria who underwent liver transplantation between September 1991 and December 2003 METHODS: We retrospectively reviewed the clinical data from 15 liver transplant recipients and the explanted livers were assessed for the efficacy of preoperative therapy. Patient survival and tumor recurrence were evaluated as primary outcome measures RESULTS: The mean age of the patients was 49.2 ± 14.3 years and hepatitis C was the etiology of the underlying liver disease in 60%. Preoperative therapy, either chemoembolization or percutaneous ethanol injection, was performed in 12 (86% patients. Complete necrosis of all tumoral lesions were observed in 5 of 12 patients (44,66%; all others had variable amounts of viable tumor in the explanted liver. Only 4 of the 15 (26.6% explanted livers had microscopic vascular invasion. The median post-transplant follow-up was 33 months (range: 8-71months and no tumor recurrence was detected during this period. The only death was an early event not related to the tumor. The recurrence-free survival rates at 1 and 3 years were 93% CONCLUSION: Liver transplantation has emerged as a good alternative for cirrhotic patients with early hepatocellular carcinoma not amenable to curative resection, offering excellent recurrence-free survival rates.

    Reconstruction of the eyebrow has historically been accomplished with temporal scalp pedicle flap formation or free composite scalp grafts. These two techniques may be associated with substantial morbidity and a false, overly dense eyebrow appearance. Hair transplantation of the eyebrows has been described with excellent results, but is relatively underreported in the literature. To determine whether modern techniques of micrograft hair transplantation can suitably re-create an aesthetic eyebrow in a case of iatrogenic eyebrow alopecia. A 33-year-old woman with iatrogenic eyebrow alopecia underwent four sessions of eyebrow micrograft hair transplantation to re-create both eyebrows. Suitable aesthetic eyebrows were re-created in a symmetric fashion with proper hair orientation. The process was time consuming and tedious, but highly effective. Eyebrow transplantation is a suitable alternative to pedicle flap formation and composite scalp grafting. It is a straightforward procedure that can be performed in the office under local anesthesia with minimal attendant morbidity. The result may be superior to that seen with more involved eyebrow replacement procedures.

    We investigated the effect of pregnane X receptor (PXR) polymorphisms on tacrolimus (FK506) blood trough concentrations and the associated adverse reactions in kidney transplantation recipients (KTRs). Polymerase chain reaction (PCR)-restriction fragment length polymorphism was used to detect the genotypes of single nucleotide polymorphism loci in 336 KTRs. The PXR six-base deletion mutation was classified using specific allele PCR, and the FK506 blood trough concentration in the KTRs was measured by chemiluminescent microparticle immunoassay. There were significant differences in adverse reactions resulting from FK506 in age, weight, body mass index (BMI) and treatment course (P adverse reactions induced by hyperglycemia. The KTRs' PXR rs3842689, rs6785049, and rs1523127 mutation frequencies were 26.07, 11.79, and 16.07%, respectively. There was no statistically significant difference in the mutation frequency of each locus between the control group and the adverse reaction groups. Therefore, rs3842689, 7635G>A (rs6785049), and 24381C>A (rs1523127) PXR polymorphisms have no obvious impact on FK506; furthermore, the PXR rs3842689 wild-type homozygous WW genotype is a risk factor of FK506 and results in gastrointestinal reactions.

    There are several possible options to treat focal articular cartilage defects of the knee. The aim of this study was to evaluate the results and prognostic factors cartilage defects of the knee treated by autologous osteochondral mosaicplasty after more than five years of follow-up. One hundred forty-two cases were included in this retrospective multicenter study. Etiologies included osteochondral fractures (n=79), and osteochondritis dissecans (n=61). Mean age of patients was 31. There was a majority of men (76%). Mean BMI was 25 (range: 21-41). Fifty-three percent of the knees had a history of surgery. Mean delay between the accident and surgery was 2.5 years. Mean area of the defect was 2.29 cm(2) (range: 0.3-12.25 cm(2)). The depth of the defect was 3 or 4 on the ICRS score in 97% of cases. An additional surgical procedure was associated with mosaicplasty in 14% of the cases. The follow-up evaluation was based on the Hughston score, the ICRS score, the IKDC subjective score, and the IKDC radiological score. Evaluation of control MRI was based on a modified MOCART score. The mean follow-up was 96 ± 28 months. There were complications in 19 patients. Patients were able to begin athletic activities again after a mean 35 weeks. Most patients (81.8%) were satisfied or very satisfied. There was a significant improvement (p<0.001) in the ICRS, IKDC function and Hughston scores at follow-up. The factors for a good prognosis were: male gender, medial femoral condyle defects, osteochondritis dissecans, deep, small defects, and the shortest possible delay to surgery. Obesity, smoking, work-related accidents, the level of sports practiced, the percentage of coverage of the defect, the number of plugs, and associated lesions did not have a statistically significant effect on the functional results in the final follow-up. Autologous osteochondral mosaicplasty seems to be a reliable technique in the short and intermediate term. It has the advantage of being less expensive

    The purpose of this study is to investigate the role of femoral marrow MR imaging as predictor of outcome for hemopoietic stem cell transplantation (HSCT) in beta-thalassemia major. MR imaging of the proximal femur, including T1- and T2-weighted spin echo and short-tau inversion recovery and in-phase and out-of-phase fast field echo images, was prospectively performed in 27 thalassemia major patients being prepared for HSCT. The area of red marrow and its percentage of the proximal femur were measured, and the presence of marrow hemosiderosis was assessed. Age-adjusted multivariate logistic regression was used to determine the relationship between red marrow area percentage and marrow hemosiderosis and HSCT outcome. Red area percentage were less in patients with successful (90.25±4.14%) compared to unsuccessful transplants (94.54% ±2.93%; p=0.01). Red marrow area percentage correlated positively with duration of symptoms(r=0.428, p=0.026) and serum ferritin (r=0.511, p=0.006). In multivariate-adjusted logistic regression analyses, red marrow area percentage was significantly inversely associated with successful HSCT (OR=1.383, 95% CI: 1.059-1.805, p=0.005). Marrow hemosidersosis and duration of sympotms and serum ferritin were not associated with HSCT outcome(p=0.174, 0.974, 0.762, respectively). Red marrow area percentage of proximal femur on MR imaging is a useful predictor of HSCT outcome. (orig.)

    Importance Bronchiolitis obliterans syndrome has been associated with increased morbidity and mortality after allogeneic hematopoietic stem cell transplant (HSCT). Previous studies have suggested that azithromycin may reduce the incidence of post–lung transplant bronchiolitis obliterans syndrome. Objective To evaluate if the early administration of azithromycin can improve airflow decline–free survival after allogeneic HSCT. Design, Setting, and Participants The ALLOZITHRO parallel-group trial conducted in 19 French academic transplant centers and involving participants who were at least 16 years old, had undergone allogeneic HSCT for a hematological malignancy, and had available pretransplant pulmonary function test results. Enrollment was from February 2014 to August 2015 with follow-up through April 26, 2017. Interventions Patients were randomly assigned to receive 3 times a week either 250 mg of azithromycin (n = 243) or placebo (n = 237) for 2 years, starting at the time of the conditioning regimen. Main Outcomes and Measures The primary efficacy end point was airflow decline–free survival at 2 years after randomization. Main secondary end points were overall survival and bronchiolitis obliterans syndrome at 2 years. Results Thirteen months after enrollment, the independent data and safety monitoring board detected an unanticipated imbalance across blinded groups in the number of hematological relapses, and the treatment was stopped December 26, 2016. Among 480 randomized participants, 465 (97%) were included in the modified intention-to-treat analysis (mean age, 52 [SD, 14] years; 75 women [35%]). At the time of data cutoff, 104 patients (22%; 54 azithromycin vs 50 placebo) had experienced an airflow decline; 138 patients (30%) died (78 azithromycin vs 60 placebo). Two-year airflow decline–free survival was 32.8% (95% CI, 25.9%-41.7%) with azithromycin and 41.3% (95% CI, 34.1%-50.1%) with placebo (unadjusted hazard ratio [HR], 1.3; 95% CI, 1

    The purpose of this article is to share observations made after performing 90 consecutive micrograft and minigraft megasessions for the treatment of male pattern baldness. Micrograft means grafts with 1 or 2 hairs, minigrafts are those with 3 or 4 hairs, and a megasession is a procedure in which more than 1000 micrografts and minigrafts are inserted in a single session. Between March of 1994 and June of 1996, the author performed 90 consecutive micrograft and minigraft megasessions on 86 men and 4 women ranging from 21 to 67 years of age (average age, 42 years). The surgical team consisted of three surgical assistants and a plastic surgeon. Today, usually between 1500 and 2000 grafts per session are performed in about 4 to 6 hours, with up to 2495 grafts done in a single session. All procedures were done under intravenous sedation and local anesthesia. A donor horizontal ellipse of scalp is harvested from the occipital area; the grafts are made out of it and then inserted through small slits. The procedure has been found to be safe and predictable with natural and aesthetically pleasing results, and there were no serious complications. The only complication found in this group was self-resolving inclusion cysts (ingrown hairs) occurring in 9 of 90 patients (10 percent). Even though the hair density achieved in a single megasession is limited, there is a high level of patient satisfaction: 83 of 85 patients were satisfied (97.65 percent).

    HRV infections are generally self-limiting in healthy subjects, whereas in immunocompromised hosts HRV infections can lead to severe complications and persistent infections. The persistence of HRV shedding could be due to the inefficient immunological control of a single infectious episode. To investigate the clinical, virologic and immunologic characteristics of pediatric HSCT recipients with HRV-PI infection. During the period 2006-2012, eight hematopoietic stem cell transplant (HSCT) recipients presented with persistent rhinovirus infection (HRV-PI, ≥30 days). Viral load and T-CD4(+), T-CD8(+), B and NK lymphocyte counts at the onset of infection were compared with those of fourteen HSCT recipients with acute HRV infection (HRV-AI, ≤15 days). The median duration of HRV positivity in patients with HRV-PI was 61 days (range 30-174 days) and phylogenetic analysis showed the persistence of a single HRV type in all patients (100%). In HSCT recipients with HRV-PI, T-CD4(+), T-CD8(+) and NK cell counts at the onset of infection were significantly lower than those observed in recipients with HRV-AI (pimmunity in HRV clearance and highlights the importance of its recovery for the control of HRV infection in HSCT recipients.

    The M2.4-7A Arrow Wing HSCT configuration was optimized for straight and level cruise at a Mach number of 2.4 and a lift coefficient of 0.10. A quasi-Newton optimization scheme maximized the lift-to-drag ratio (by minimizing drag-to-lift) using Euler solutions from FL067 to estimate the lift and drag forces. A 1.675% wind-tunnel model of the Opt5 HSCT configuration was built to validate the design methodology. Experimental data gathered at the NASA Langley Unitary Plan Wind Tunnel (UPWT) section #2 facility verified CFL3D Euler and Navier-Stokes predictions of the Opt5 performance at the design point. In turn, CFL3D confirmed the improvement in the lift-to-drag ratio obtained during the optimization, thus validating the design procedure. A data base at off-design conditions was obtained during three wind-tunnel tests. The entry into NASA Langley UPWT section #2 obtained data at a free stream Mach number, M(sub infinity), of 2.55 as well as the design Mach number, M(sub infinity)=2.4. Data from a Mach number range of 1.8 to 2.4 was taken at UPWT section #1. Transonic and low supersonic Mach numbers, M(sub infinity)=0.6 to 1.2, was gathered at the NASA Langley 16 ft. Transonic Wind Tunnel (TWT). In addition to good agreement between CFD and experimental data, highlights from the wind-tunnel tests include a trip dot study suggesting a linear relationship between trip dot drag and Mach number, an aeroelastic study that measured the outboard wing deflection and twist, and a flap scheduling study that identifies the possibility of only one leading-edge and trailing-edge flap setting for transonic cruise and another for low supersonic acceleration.

    2017-10-01

    Full Text Available Human pluripotent stem cell (hPSC-derived mesencephalic dopaminergic (mesDA neurons can relieve motor deficits in animal models of Parkinson's disease (PD. Clinical translation of differentiation protocols requires standardization of production procedures, and surface-marker-based cell sorting is considered instrumental for reproducible generation of defined cell products. Here, we demonstrate that integrin-associated protein (IAP is a cell surface marker suitable for enrichment of hPSC-derived mesDA progenitor cells. Immunomagnetically sorted IAP+ mesDA progenitors showed increased expression of ventral midbrain floor plate markers, lacked expression of pluripotency markers, and differentiated into mature dopaminergic (DA neurons in vitro. Intrastriatal transplantation of IAP+ cells sorted at day 16 of differentiation in a rat model of PD resulted in functional recovery. Grafts from sorted IAP+ mesDA progenitors were more homogeneous in size and DA neuron density. Thus, we suggest IAP-based sorting for reproducible prospective enrichment of mesDA progenitor cells in clinical cell replacement strategies.

    The increasing number of patients on waiting lists and the relatively stable organ procurement rate provide the groundwork for the use of expanded criteria deceased donors. While calcineurin-inhibitors (CNI) are excellent immunosuppressive drugs, their nephrotoxicity is largely responsible for the lack of improvement in long-term graft survival. The objective of this study was to analyze the results obtained with the use of a calcineurin inhibitor-free immunosuppressive protocol (polyclonal antibody induction, plus sirolimus, mycophenolate mofetil, and low doses of steroids) in terms of graft and patient survival as well as posttransplant clinical complications over 2 years. Under this immunosuppressive protocol, 78.04% of the patients completed the follow-up. A protocol biopsy was performed on 17 patients (53.1%) within 2 years posttransplant of which 82.31% were diagnosed as chronic allograph nephropathy grade I. The incidence of clinical complications was low and not significantly different from that reported with other immunosuppressive schemes. Death-censored graft survival was 95.12%. In conclusion, the use of a calcineurin inhibitor-free protocol in renal-transplant recipients of expanded criteria deceased donors was associated with excellent graft and patient survival rates and a low incidence of adverse events.

    to treat special cases of intestinal failure. AIM: This review highlights recent developments in the area of small bowel transplantation. MATERIAL AND METHODS: Over 600 reports on clinical and experimental small bowel transplantation were reviewed. Aspects concerning research development, different immunosuppressive strategies, patient and graft monitoring, and improvements in surgical techniques are discussed. RESULTS: About 700 small bowel transplantation were performed in 55 transplant centers, 44% intestine-liver, 41% isolated intestinal graft and 15% multivisceral transplantation. Rejection and infection are the main limitation of this procedure. Actual 5 years post transplantation graft survival of the total international experience is 46% for isolated intestinal graft, 43% for combined intestine-liver and nearly 30% for multivisceral transplantation. Higher graft and patient survival are seen at the more experienced centers. In a series of 165 intestinal transplantation at University of Pittsburgh, PA, USA, actuarial patient survival was reported to be over 75% at one year, 54% at 5 years and 42% at 10 years. Over 90% patients from Pittsburgh program resume an unrestricted oral diet. CONCLUSION: Small bowel transplantation has advanced from an experimental strategy to a feasible alternative for patients with permanent intestinal failure. Further refinements in graft acceptance, immunosuppressive regiments, infection management and prophylaxis, surgical techniques as well as appropriated patient referral and selection are crucial to improve outcomes.

    Here, we described the clinical characteristics and outcomes of central nervous system (CNS) infections occurring after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in a single institution over the previous 6 years. Charts of 353 consecutive allogeneic transplant recipients were retrospectively reviewed for CNS infection. A total of 17 cases of CNS infection were identified at a median of 38 days (range, 10-1028 days) after allo-HSCT. Causative pathogens were human herpesvirus-6 (n=6), enterococcus (n=2), staphylococcus (n=2), streptococcus (n=2), varicella zoster virus (n=1), cytomegalovirus (n=1), John Cunningham virus (n=1), adenovirus (n=1), and Toxoplasma gondii (n=1). The cumulative incidence of CNS infection was 4.1% at 1 year and 5.5% at 5 years. Multivariate analysis revealed that high-risk disease status was a risk factor for developing CNS infection (p=.02), and that overall survival at 3 years after allo-HSCT was 33% in patients with CNS infection and 53% in those without CNS infection (p=.04).

    PurposeTo evaluate long-term results of stent placement retrospectively in patients with outflow block after living-donor-liver transplantation (LDLT).Materials and MethodsFor this institutional review board approved retrospective study conducted during 2002–2012, stents were placed in outflow veins in 15 patients (11.3 %, 15/133) (12 men; 3 female) in whom outflow block developed after LDLT. Their mean age was 52.3 years ± 15.3 (SD) (range, 4–69 years). Venous stenosis with a pressure gradient ≥5 mmHg (outflow block) was observed in the inferior vena cava in seven patients, hepatic vein in seven patients, and both in one patient. Technical success, change in a pressure gradient and clinical manifestations, and complications were evaluated. Overall survival of 15 patients undergoing outflow block stenting was compared with that of 116 patients without outflow block after LDLT.ResultsStents were placed across the outflow block veins without complications, lowering the pressure gradient ≤ 3 mmHg in all patients (100 %, 15/15). Clinical manifestations improved in 11 patients (73.3 %, 11/15), and all were discharged from the hospital. However, they did not improve in the other 4 patients (26.7 %, 4/15) who died in the hospital 1.0–3.7 months after stenting (mean, 2.0 ± 1.2 months). No significant difference in 5-year survival rates was found between patients with and without outflow block after LDLT (61.1 vs. 72.2 %, p = .405).ConclusionStenting is a feasible, safe, and useful therapeutic option to resolve outflow block following LDLT, providing equal survival to that of patients without outflow block.

    In this retrospective study, we analyzed the outcomes of 129 patients who underwent an allogeneic hematopoietic stem cell transplantation (allo-HSCT) and had a history of probable or proven invasive aspergillosis (IA), of whom 57 (44%) received a reduced-intensity conditioning (RIC). Overall, 27 patients with IA progressed after the allo-HSCT (cumulative incidence [CumInc] at 2 years, 22%). The variables that increased the 2-year CumInc of IA progression were (1) longer duration of neutropenia after transplantation; (2) advanced status of the underlying disease; and (3) less than 6 weeks from start of systemic anti-Aspergillus therapy and the allo-HSCT. In addition, (4) conventional myeloablative conditioning increased the risk of progression early after transplantation (before day 30) only, while 3 variables increased the risk beyond day 30 were (5) cytomegalovirus disease; (6) bone marrow or cord blood as source of stem cells; and (7) grades II to IV acute graft-versus-host disease (GVHD). A risk model for progression was generated, defined as low (0-1 risk factors, 6% incidence), intermediate (2-3 risk factors, 27% incidence), or high risk (> or = 3 risk factors, 72% incidence [P < .001]). These findings may help in the interpretation and design of future studies on secondary prophylaxis of IA after an allo-HSCT.

    Hematopoietic stem cell transplantation (HSCT) is a highly successful treatment for severe congenital immunodeficiencies. However, some studies have suggested that children may experience cognitive difficulties after HSCT. This large-scale study assessed cognitive and behavioral function for the cohort of children treated by HSCT at one center between 1979 and 2003 to determine the frequency and severity of problems and to identify risk factors. A total of 105 patients were assessed on standardized measures of cognitive and emotional and behavioral function together with a control group of unaffected siblings. The average IQ for the cohort was 85 (95% confidence interval, 81-90), significantly lower than both the population average of 100 (P severe combined immunodeficiency, and consanguinity were associated with worse outcome but that age at transplantation and chemotherapy conditioning were not. Children treated by HSCT for severe immunodeficiency have an increased risk of long-term cognitive difficulties and associated emotional and behavioral difficulties. The specific genetic diagnosis, consanguinity, and severe clinical course are associated with poor outcome. Long-term follow-up of these patients should include screening to identify and manage these problems more effectively.

    Protective immunity to vaccine preventable infectious diseases might be lost over time following hematopoietic stem cell transplantation (HSCT). Limited data are available on the appropriate follow-up of vaccination schedules in pediatric HSCT patients. This study aims to ascertain whether the guidelines for vaccination recommended in our hospital are followed and to which extent of conformity they are used. A 5-year survey, including all pediatric allogeneic HSCT patients, transplanted at the Ghent University hospital, Belgium. Data were collected from the patient's electronic (nursing and medical) charts. Data on vaccination schedules of 28 patients (54.9%) eligible for the recommended vaccinations were collected. Eleven patients (11/28; 39.3%) were vaccinated timely. In 14 out of 17 patients (82.4%) vaccination was postponed for medical reasons, while vaccination was postponed without medical reason in 17.6% (3/17). Vaccination data could not be retrieved in 43.1 (22/51) of patients. Vaccination was declined by the parents in one patient (2.0%). There is high level of agreement between the hospital guideline and the vaccination of pediatric HSCT patients. Health-care providers play a crucial role in effectively appropriate follow-up of vaccination schedules. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Immune recovery after profound lymphopenia is a major challenge in many clinical situations, such as allogeneic hematopoietic stem cell transplantation (allo-HSCT). Recovery depends, in a first step, on hematopoietic lymphoid progenitors production in the bone marrow (BM). In this study, we characterized CD34+Lin−CD10+ lymphoid progenitors in the peripheral blood of allo-HSCT patients. Our data demonstrate a strong recovery of this population 3 months after transplantation. This rebound was abolished in patients who developed acute graft-versus-host disease (aGVHD). A similar recovery profile was found for both CD24+ and CD24− progenitor subpopulations. CD34+lin−CD10+CD24− lymphoid progenitors sorted from allo-HSCT patients preserved their T cell potentiel according to in vitro T-cell differentiation assay and the expression profile of 22 genes involved in T-cell differentiation and homing. CD34+lin−CD10+CD24− cells from patients without aGVHD had reduced CXCR4 gene expression, consistent with an enhanced egress from the BM. CCR7 gene expression was reduced in patients after allo-HSCT, as were its ligands CCL21 and CCL19. This reduction was particularly marked in patients with aGVHD, suggesting a possible impact on thymic homing. Thus, the data presented here identify this population as an important early step in T cell reconstitution in humans and so, an important target when seeking to enhance immune reconstitution.

    After a kidney transplantation, patients have to visit the hospital often to monitor for early signs of graft rejection. Self-monitoring of creatinine in addition to blood pressure at home could alleviate the burden of frequent outpatient visits, but only if patients are willing to self-monitor and if they adhere to the self-monitoring measurement regimen. A prospective pilot study was conducted to assess patients' experiences and satisfaction. For 3 months after transplantation, 30 patients registered self-measured creatinine and blood pressure values in an online record to which their physician had access to. Patients completed a questionnaire at baseline and follow-up to assess satisfaction, attitude, self-efficacy regarding self-monitoring, worries, and physician support. Adherence was studied by comparing the number of registered with the number of requested measurements. Patients were highly motivated to self-monitor kidney function, and reported high levels of general satisfaction. Level of satisfaction was positively related to perceived support from physicians (Pself-efficacy (Pmonitoring of creatinine and blood pressure after transplantation offers a promising strategy. Important prerequisites for safe implementation in transplant care seem to be support from physicians and patients' confidence in both their own self-monitoring skills and the accuracy of the devices used.

    Full Text Available Allogeneic hematopoietic stem cell transplantation (HSCT represents a curative treatment for many patients with hematological malignant or non-malignant disorders. Evaluation of potential donors for HSCT includes a rigorous assessment of the human leukocyte antigens (HLA match status of family members, and the identification of suitable unrelated donors. Genes encoding transplantation antigens are placed both within and outside the major histocompatibility complex (MHC. The human MHC is located on the short arm of chromosome 6 and contains a series of genes encoding two distinct types of highly polymorphic cell surface glycoproteins. Donors for HSCT are routinely selected based on the level of matching for HLA-A, -B, -C, -DRB1, and -DQB1 loci. However, disease relapse, graft-versus-host-disease, and infection remain significant risk factors of morbidity and mortality. In the same breath, in high-risk patients, graft-versus-leukemia effects inherent in HLA mismatching play a substantial immunological role to limit the recurrence of post-transplant disease. The definition of a suitable donor is ever changing, shaped not only by current typing technology, but also by the specific transplant procedure. Indeed, a more complete understanding of permissible HLA mismatches and the role of Killer Immunoglobulin-like receptors’ genes increases the availability of HLA-haploidentical and unrelated donors.

    Sarcopenia and functional impairment are common and lethal extrahepatic manifestations of cirrhosis. We aimed to determine the association between computed tomography (CT)-based measures of muscle mass and quality (sarcopenia) and performance-based measures of muscle function. Adults listed for liver transplant underwent testing of muscle function (grip strength, Short Physical Performance Battery [SPPB]) within 3 months of abdominal CT. Muscle mass (cm/m) = total cross-sectional area of psoas, paraspinal, and abdominal wall muscles at L3 on CT, normalized for height. Muscle quality = mean Hounsfield units for total skeletal muscle area at L3. Among 292 candidates, median grip strength was 31 kg, SPPB score was 11, muscle mass was 49 cm/m, and muscle quality was 35 Hounsfield units. Grip strength weakly correlated with muscle mass (ρ = 0.26, P strength (hazard ratio [HR], 0.74; 95% confidence interval [95% CI], 0.59-0.92; P = 0.008), SPPB (HR, 0.89; 95% CI, 0.82-0.97; P = 0.01), and muscle quality (HR, 0.77; 95% CI, 0.63-0.95; P = 0.02) were associated with waitlist mortality, but muscle mass was not (HR, 0.91; 95% CI, 0.75-1.11; P = 0.35). Performance-based tests of muscle function are only modestly associated with CT-based muscle measures. Given that they predict waitlist mortality and can be conducted quickly and economically, tests of muscle function may have greater clinical utility than CT-based measures of sarcopenia.

    Autoimmune hemolytic anemia (AIHA) is a clinically relevant complication after allogeneic hematopoietic stem cell transplantation (HSCT). Currently, there is no established consensus regarding the optimal therapeutic approach. Whether AIHA contributes to increased mortality is still somewhat controversial.We investigated the incidence, risk factors, and outcome of post-transplant AIHA in 265 consecutive pediatric patients undergoing allo-HSCT over a 17-year period. Onset of AIHA was calculated from the first documented detection of AIHA by either clinical symptoms or positive direct agglutinin test. Resolution of AIHA was defined as normalization of hemoglobin and biochemical markers of hemolysis with sustained transfusion independence.We identified 15 cases of AIHA after allo-HSCT (incidence rate, 6%). Ten (67%) of these patients had a positive direct antiglobulin test. Data were obtained for 9 boys and 6 girls after a median follow-up of 53 months (range 4-102). The median age was 5.1 years (range 0.5-15.4) at the time of HSCT and the median time to emergence was 149 days (range 42-273). No significant risk factor for post-transplant AIHA has emerged from our data to date. In the majority (14 of 15; 93%) of AIHA patients, multiple agents for treatment were required, with 12 of 15 (80%) patients achieving complete resolution of AIHA. No splenectomy was performed in any of our patients.For various reasons, post-transplantation AIHA poses an extraordinary challenge to transplant physicians. Despite the advancements in diagnostic tools, therapeutic challenges remain due to the myriad interacting pathways in AIHA.

    Purpose Approximately 13% of patients lacking an HLA-identical sibling have a 1-antigen-mismatched related donor (MMRD). Historically, outcomes using a 1-antigen MMRD were considered equivalent to a matched unrelated donor (UD). Recent improvements in unrelated donor (UD) stem cell transplantation (SCT) due to better molecular HLA-matching justifies investigating if UD should be preferred to MMRD in adult patients with acute leukemia. Patients and Methods The outcomes of MMRD (n=89) and HLA-A, B, C, DRB1 allele matched UD (n=700) SCT reported to the CIBMTR between 1995 and 2005 were compared. Patients were transplanted for acute myeloid leukemia (AML) or acute lymphoid leukemia (ALL) in first or second complete remission. Results Donor type was not associated with hematological recovery. Univariate and multivariate comparisons of MMRD vs. HLA-matched UD transplants showed no statistically significant differences in overall survival, disease free survival, transplant related mortality, relapse, and 100-day grade III–IV acute graft-versus-host disease (GVHD). MMRD SCT was associated with a lower rate of chronic GVHD at 1-year, 35% vs 47% p=0.03, which was confirmed in multivariate analysis (RR 0.58, 95% CI 0.39-0.85, p<0.01). Conclusion HLA-matched UD and MMRD SCT are associated with comparable survival. Since less chronic GVHD was observed in MMRD, this option when available remains the first choice in acute leukemia patients without an HLA-identical sibling in need of allogeneic transplantation.

    Recurrence of prior invasive fungal infection (relapse rate of 30-50%) limits the success of stem cell transplantation. Secondary prophylaxis could reduce disease burden and improve survival. A prospective, open-label, multicenter trial was conducted evaluating voriconazole (4 mg/kg/12 h intravenously or 200 mg/12 h orally) as secondary antifungal prophylaxis in allogeneic stem cell transplant recipients with previous proven or probable invasive fungal infection. Voriconazole was started 48 h or more after completion of conditioning chemotherapy and was planned to be continued for 100-150 days. Patients were followed for 12 months. The primary end-point of the study was the incidence of proven or probable invasive fungal infection. Forty-five patients were enrolled, 41 of whom had acute leukemia. Previous invasive fungal infections were proven or probable aspergillosis (n=31), proven candidiasis (n=5) and other proven or probable infections (n=6); prior infection could not be confirmed in three patients. The median duration of voriconazole prophylaxis was 94 days. Eleven patients (24%) died within 12 months of transplantation, but only one due to systemic fungal disease. Three invasive fungal infections occurred post-transplant: two relapses (one candidemia and one fatal scedosporiosis) and one new zygomycosis in a patient with previous aspergillosis. The 1-year cumulative incidence of invasive fungal disease was 6.7±3.6%. Two patients were withdrawn from the study due to treatment-related adverse events (i.e. liver toxicity). Voriconazole appears to be safe and effective for secondary prophylaxis of systemic fungal infection after allogeneic stem cell transplantation. The observed incidence of 6.7% (with one attributable death) is considerably lower than the relapse rate reported in historical controls, thus suggesting that voriconazole is a promising prophylactic agent in this population.

    Bloodstream infections (BSIs) are a leading cause of morbidity and mortality in children undergoing hematopoietic stem cell transplant (HSCT). Indwelling central venous catheters (CVCs) increase risk for BSIs, yet mucosal barrier injury-associated laboratory-confirmed bloodstream infection (MBI-LCBI) may also occur due to translocation of pathogenic organisms from the gastrointestinal tract into the bloodstream. The purpose of this study was to determine the association between stool organisms and BSIs in children with CVCs who underwent HSCT. We performed a retrospective analysis of 78 children who received allogeneic HSCT over 3 years (2012-2014). Surveillance stool cultures were analyzed pre- and post-HSCT to assess correlations between organisms isolated from stool and CVC cultures. Twenty-four of 78 children experienced 31 BSIs. Fifteen (48%) of these isolates were identified in stool within 30 days of the positive blood culture, and 11 (36%) isolates met criteria for MBI-LCBI. Mucosal barrier injury leads to translocation of pathogenic organisms into the bloodstream and accounts for a significant number of BSIs in children undergoing HSCT. Nursing assessment of mucosal changes during HSCT and interventions to preserve intact mucosa are essential to prevent MBI-LCBI.

    The pathogenesis of sinusoidal obstruction syndrome (SOS) and thrombotic microangiopathy (TMA) after hematopoietic stem cell transplantation (HSCT) is poorly understood, and limited information is available on global hemostatic function in HSCT. We assessed changes in coagulation and fibrinolysis using a simultaneous thrombin and plasmin generation assay (T/P-GA) during HSCT. Measurements of endogenous thrombin potential (T-EP) and plasmin peak height (P-Peak) using T/P-GA in six pediatric acute leukemia patients treated with HSCT were compared to normal plasma. In the SOS case, the ratios of T-EP and P-Peak to normal were simultaneously decreased at four weeks post-HSCT (Pre; ~1.1/1.1-1.4, Week+4; 0.14/0.0084, respectively). Similarly, in the TMA patient, both ratios were decreased at 3 weeks and recovered after 8 weeks (Pre; 1.2/~0.95, Week+3; 0.59/0.22, Week+8; 1.2/0.64-0.85). In the other patients, when SOS/TMA was not evident, the T/P-GA data remained within normal limits. These findings suggest that the simultaneous reduction of coagulation and fibrinolytic function in patients developing SOS/TMA can lead to a life-threatening coagulopathy. Further research is warranted to clarify global hemostatic function after HSCT to establish optimal supportive therapy for these critical clinical disorders of hemostasis.

    Full Text Available Over the past decade, invasive fungal infections (IFI have remained an important problem in patients undergoing allogeneic haematopoietic stem cell transplantation (Allo-HSCT. The optimal approach for prophylactic antifungal therapy has yet to be determined. We conducted a retrospective, bi-institutional comparative clinical study, and compared the efficacy and safety of micafungin 50mg/day (iv with those of fluconazole (400mg/day or itraconazole 200mg/day (iv as prophylaxis for adult patients with various haematological diseases receiving haplo-identical allogeneic stem cell transplantation (haplo. Overall, 99 patients were identified; 30 patients received micafungin, and 69 patients received fluconazole or itraconazole. After a median follow-up of 13 months (range: 5-23, Proven or probable IFIs were reported in 3 patients (10% in the micafungin group and 8 patients (12% in the fluconazole or itraconazole group. Fewer patients in the micafungin group had invasive aspergillosis (1 [3%] vs. 5 [7%], P=0.6. A total of 4 (13% patients in the micafungin group and 23 (33% patients in the fluconazole or itraconazole group received empirical antifungal therapy (P = 0.14. No serious adverse events related to treatment were reported by patients and there was no treatment discontinuation because of drug-related adverse events in both groups. Despite the retrospective design of the study and limited sample, it contributes reassuring data to confirm results from randomised clinical trials, and to define a place for micafungin in prophylaxis after haplo.

    The aim of this study was to review and discuss the great variety of ethical issues related to organ donation, organ procurement, transplant activities, and new ethical problems created as a result of technologic and scientific developments. An extensive literature survey was made, and expert opinions were obtained. The gap between demand and supply of organs for transplant has yielded to organ trafficking, organ tourism, and commercialism. This problem seems to be the most important issue, and naturally there are ethical dilemmas related to it. A wide number of ideas have been expressed on the subject, and different solutions have been proposed. The struggle against organ trafficking and commercialism should include legislation, efforts to increase deceased-donor donations, and international cooperation. China's policy to procure organs from prisoners sentenced to death is unethical, and the international community should exert more pressure on the Chinese government to cease this practice. Each particular ethical dilemma should be taken separately and managed.

    Purpose Haploidentical and human leukocyte antigen (HLA)-identical sibling hematopoietic stem transplantation are two main ways used in allogeneic hematopoietic stem cell transplantation (allo-HSCT). In recent years, remarkable progress has been made in haploidentical allo-HSCT (HID-SCT), and some institutions found HID-SCT had similar outcomes as HLA-identical sibling allo-HSCT (ISD-SCT). To clarify if HID-SCT has equal effects to ISD-SCT in hematologic malignancies, we performed this meta-analysis. Methods Relevant articles published prior to February 2017 were searched on PubMed. Two reviewers assessed the quality of the included studies and extracted data independently. Odds ratio (OR) and 95% confidence intervals (CIs) were calculated for statistical analysis. Results Seven studies including 1919 patients were included. The rate of platelet engraftment is significantly lower after HID-SCT versus ISD-SCT while there is no difference in neutrophil engraftment (OR = 2.58, 95% CI = 1.70–3.93, P SCT versus ISD-SCT (OR = 1.88, 95% CI = 1.42–2.49, P SCT group (OR = 0.70, 95% CI = 0.55–0.90, P = 0.005). The incidence rates of overall survival (OS) and disease-free-survival/leukemia-free survival/relapse-free survival (DFS/LFS/RFS) after ISD-SCT are all significantly superior to HID-SCT (OR = 1.32, 95% CI = 1.08–1.62, P = 0.006; OR = 1.25, 95% CI = 1.03–1.52, P = 0.02). There is no significant difference in transplantation related mortality (TRM) rate after HID-SCT and ISD-SCT. Conclusion After myeloablative conditioning, patients receiving ISD-SCT have a faster engraftment, lower acute GVHD and longer life expectancy compared to HID-SCT with GVHD prophylaxis (cyclosporine A, methotrexate, mycophenolate mofetil and antithymoglobulin; CsA + MTX + MMF + ATG). Currently, HID-SCT with GVHD prophylaxis (CsA + MTX + MMF + ATG) may not replace ISD-SCT when HLA-identical sibling donor available. PMID:29381772

    Full Text Available Haematopoietic stem cell transplantation (HSCT improves the survival rate of children and adolescents with malignant and non-malignant conditions; however, the physical, psychological and social burden of such a procedure is considerable both during and after treatment. The present qualitative study investigated the long-term effects of HSCT after pediatric cancer. Thirty adolescent and young adult (AYA survivors (Mage = 23.61 years, SD = 5.21 participated in individual interviews and were invited to speak about their life experiences following their treatment and strategies they use to deal with their past medical experiences and the long-term sequelae. Our results showed the presence of ongoing physical and psychosocial consequences of their past illness and its treatments with wide ranging psychosocial impacts, such as affected self-image, social withdrawal, sense of lack of choice, and need for specific attention. Different strategies were reported to overcome these consequences, such as talking about illness, giving a sense to their past medical experiences, and developing meaningful social relationships. Clinical and research implications are also discussed.

    Full Text Available Abstract Background Bortezomib, an NFkB inhibitor, is an active agent for the treatment of myeloma (MM. We have reported a promising complete remission (CR rate for newly diagnosed myeloma patients treated by a staged approach, in which chemosensitive patients underwent autologous haematopoietic stem cell transplantation (auto-HSCT while less chemosensitive patients received salvage therapy with bortezomib/thalidomide/dexamethasone prior to auto-HSCT. Methods Herein, with an additional 13 months of follow-up, we reported the updated survivals, and examined potential prognostic factors impacting event-free (EFS and overall survival (OS. Results With a median follow-up of 30 months, the projected OS was 73% and EFS was 50.2%. Age, gender, clinical stage and DAPK methylation could not account for the differential chemosensitivity. Advanced ISS stage and DAPK methylation adversely impacted OS whereas oligoclonal reconstitution predicted superior EFS. Conclusions Our staged approach illustrated an economical use of expensive targeted agents while preserving a good CR rate and OS. The comparable survivals of chemosensitive and less chemosensitive patients suggested the staged approach might have abolished the adverse prognostic impact of suboptimal chemosensitivity. Finally, the adverse impact of DAPK methylation and favorable impact of oligoclonal reconstitution in myeloma warrants further study.

  1. Immune System and Kidney Transplantation.

    The immune system recognises a transplanted kidney as foreign body and mounts immune response through cellular and humoral mechanisms leading to acute or chronic rejection, which ultimately results in graft loss. Over the last five decades, there have been significant advances in the understanding of the immune responses to transplanted organs in both experimental and clinical transplant settings. Modulation of the immune response by using immunosuppressive agents has led to successful outcomes after kidney transplantation. The paper provides an overview of the general organisation and function of human immune system, immune response to kidney transplantation, and the current practice of immunosuppressive therapy in kidney transplantation in the United Kingdom.

    Full Text Available An 8-year old boy, affected by severe aplastic anemia, developed a probable pulmonary invasive aspergillosis (IA early after a second unrelated allogeneic hematopoietic stem cell transplant (HSCT. He was treated promptly with the combination of liposomal amphotericin B and caspofungin. Despite the initial stabilization, the patient deteriorated and the antifungal therapy was switched to voriconazole and caspofungin. The patient gradually improved and was discharged home on day +29 post-HSCT on oral voriconazole. On day +119, a sudden episode of hemoptysis occurred and a right superior lobectomy was decided to remove the residual aspergilloma. The patient is now alive and well more than 24 months from HSCT. This case demonstrated that antifungal combination therapy and surgery are valid options to cure pulmonary IA even in patients at high-risk and severely immunosuppressed.

    Invasive Zygomycetes infection complicating prolonged neutropenia is associated with high mortality in the absence of immune recovery. We report a patient who developed disseminated zygomycosis due to Rhizopus microsporus during induction chemotherapy for acute myeloid leukemia. Rescue allogeneic hematopoietic stem cell transplantation (allo-HSCT) was performed as her only chance of cure of this infection and to treat refractory leukemia. Posaconazole combined with liposomal amphotericin B contained the zygomycosis during prolonged neutropenia due to allo-HSCT followed by intense immunosuppression for grade IV acute graft-versus-host disease. Surgical removal of all infected sites after immune recovery, with prolonged posaconazole treatment, ultimately cured the infection. New combination antifungal therapies might sufficiently control disseminated zygomycosis to allow allo-HSCT to be performed, assuring life-saving immune recovery. Surgery appears to be necessary for definite cure of these infections.

    Relapsed/refractory acute lymphoblastic leukemia (ALL) has a low remission rate after chemotherapy, a high relapse rate and poor long-term survival even when allogeneic hematopoietic stem cell transplantation (allo-HSCT) is performed. Chimeric antigen receptors redirected T cells (CAR-T cells) can enhance disease remission with a favorable outcome for relapsed/refractory ALL, though some cases quickly relapsed after CAR-T cell treatment. Thus, treatment with CAR-T cells followed by allo-HSCT may be the best way to treat relapsed/refractory ALL. In this review, we first discuss the different types of CAR-T cells. We then discuss the treatment of relapsed/refractory ALL using only CAR-T cells. Finally, we discuss the use of CAR-T cells, followed by allo-HSCT, for the treatment of relapsed/refractory ALL.

    Hematopoieticic stem cell transplantation is the only therapeutic option that can cure thalassemia disease. Reduced intensity hematopoietic stem cell transplantation (RI-HSCT) has demonstrated a high cure rate with minimal complications compared to other options. Because RI-HSCT is very costly, economic justification for its value is needed. This study aimed to estimate the cost-utility of RI-HSCT compared with blood transfusions combined with iron chelating therapy (BT-ICT) for adolescent and young adult with severe thalassemia in Thailand. A Markov model was used to estimate the relevant costs and health outcomes over the patients' lifetimes using a societal perspective. All future costs and outcomes were discounted at a rate of 3% per annum. The efficacy of RI-HSCT was based a clinical trial including a total of 18 thalassemia patients. Utility values were derived directly from all patients using EQ-5D and SF-6D. Primary outcomes of interest were lifetime costs, quality adjusted life-years (QALYs) gained, and the incremental cost-effectiveness ratio (ICER) in US ($) per QALY gained. One-way and probabilistic sensitivity analyses (PSA) were conducted to investigate the effect of parameter uncertainty. In base case analysis, the RI-HSCT group had a better clinical outcomes and higher lifetime costs. The incremental cost per QALY gained was US $3,236 per QALY. The acceptability curve showed that the probability of RI-HSCT being cost-effective was 71% at the willingness to pay of 1 time of Thai Gross domestic product per capita (GDP per capita), approximately US $4,210 per QALY gained. The most sensitive parameter was utility of severe thalassemia patients without cardiac complication patients. At a societal willingness to pay of 1 GDP per capita, RI-HSCT was a cost-effective treatment for adolescent and young adult with severe thalassemia in Thailand compared to BT-ICT.

    After hematopoietic stem cell transplantation (HSCT), successful engraftment and immune recovery is necessary to protect the patient from relapse and infection. Many studies highlight the importance of conventional αβ T cell recovery after HSCT, but the impact of γδ T cell recovery has not been well described. Here, we investigate the recovery of γδ T cells in 102 pediatric patients with acute leukemia in first clinical remission who underwent allogeneic HSCT at St. Jude Children's Research Hospital from 1996 to 2011. Mean patient age was 10.5 ± 5.9 years (range, .6 to 25.2), and mean survivor follow-up was 2.7 ± 1.8 years (range, .12 to 6.0). Diagnoses included 59% patients with acute lymphoblastic leukemia and 41% patients with acute myelogenous leukemia. Multivariate analysis demonstrated significant impact of the maximum number of CD3(+), CD4(+), and CD8(+) T cells and donor source on the γδ T cell recovery (P < .0001, P < .0001, P < .0001, and P < .004, respectively). Univariate and multivariate models found the number of γδ T cells after HSCT to be associated with infections (P = .026 and P = .02, respectively). We found the probability of infections for patients with an elevated number of γδ T cells was significantly lower compared with patients with low or normal γδ T cells after HSCT (18% versus 54%; P = .025). Bacterial infections were not observed in patients with elevated γδ T cells. Finally, event-free survival was significantly higher in patients with enhanced γδ T cell reconstitution compared with patients with low/normal γδ T cell reconstitution after HSCT (91% versus 55%; P = .04). Thus, γδ T cells may play an important role in immune reconstitution after HSCT. Copyright © 2015 American Society for Blood and Marrow Transplantation. Published by Elsevier Inc.

    Full Text Available Based on the annual UNAIDS reports the number of HIVinfected patients is continually growing since 1983. Antiretroviral Therapy (ART allows to prolong life expectancy, but the problem of life quality and overall survival is still remaining. Nowadays, in the era of ART, one of the main cause of mortality in HIV-infected patients is malignancies. Lymphomas play one of the key roles in this group of diseases. The treatment of lymphomas includes combined regiments of chemotherapy with a curative potential. High dose chemotherapy with autologous hematopoietic stem cell transplant (auto-HSCT is the main path of the treatment for relapsed / refractory lymphomas. In the last few years with a development of the genome editing technology auto-HSCT is becoming one of the most promising methods of HIV treatment. The case of “Berlin patient” when allogeneic HSCT from donor with mutation CCR5-delta32 lead to cure from HIV and proof of concept the efficacy of the gene therapy for HIV based on HSCT. Hematopoietic stem cell transplantation with edited autologous HSC (CCR5 knockout by site-specific genome editing tools with engineering nucleases is a comprehensive treatment for this cohort of patients. On one hand, high dose chemotherapy with auto-HSCT cures the malignancy; on the other hand auto-HSCT works as a delivery method for the edited cells and creates an environment for the HIV eradication. This review is dedicated to HIV and oncology, methods of treatment of hematological malignancies and HIV-infection using genome editing technology based on HSCT.

    HBV reactivation is associated with high mortality rates in hematopoietic stem cell transplantation (HSCT) and prophylactic lamivudine (LMV) treatment is suggested to prevent this phenomenon. However, the duration of LMV treatment in HSCT patients is not fully defined and the time of immune recovery is considered the best parameter for a drug to be safely interrupted. In patients undergoing allogeneic HSCT, the time of immune recovery is not easy to define and may take years after transplantation and prolonged LMV treatments, which can lead to drug-resistant viral strains. An anti-HBc-positive hematological patient who was undergoing prolonged immunosuppression and who experienced HBV reactivation 3 months after the suspension of a prolonged LMV prophylaxis is described. HBV-DNA matching an atypical serological profile characterized by HbsAg negativity and anti-HBs positivity was detected in the patient. The genotypic analysis of the HBV strain identified T127P, F170FL and S204R mutations of HbsAg, which can hinder HBsAg recognition in a diagnostic assay. HBV reactivation in the HSCT host can be sustained by HBsAg viral variants with characteristics of altered immunogenicity that cannot be detected by usual laboratory tests. This clinical case description suggests the importance of screening for serum HBV-DNA levels in the diagnosis of HBV reactivation and monitoring HBV-DNA after prophylaxis suspension, particularly in HSCT subjects who have undergone prolonged periods of LMV treatment.

    This retrospective single-center study evaluated long-term renal function after conversion from calcineurin inhibitors to sirolimus-based immunosuppression in kidney transplant recipients. From 2001 to 2009, one hundred fifty kidney transplant recipients were converted from calcineurin inhibitors to sirolimus at least 3 months after transplant. After a mean follow-up of 171 weeks, 56.7% of converted patients remained on sirolimus. The 5-year survival rate of the patients (including intent-to-treat) and grafts was 85.5% and 83.6%. Patients on sirolimus showed significant improvement in renal function with a creatinine clearance of 50.9 ± 20.7 and 52.9 ± 20.8 mL/minute at month 0 and month 24. Independent predictive factors associated with a stable estimated glomerular filtration rate at the last follow-up of sirolimus patients were (1) having a living donor, (2) absence of anti-HLA alloantibodies at month 0, and (3) cyclosporine versus tacrolimus used before conversion. Adverse effects were reported in 134 patients (89.3%). They included (1) hospitalization for infection (n=52), (2) de novo proteinuria (n=40), and (3) eight patients with biopsy-proven acute rejection. Sirolimus was stopped and replaced by calcineurin inhibitors in 37 patients after a mean of 16 months treatment. After stopping sirolimus, renal-allograft function remained stable at 2 years. Conversion of calcineurin inhibitors to sirolimus in kidney transplant recipients was associated with improved renal function. The reintroduction of calcineurin inhibitors was safe in patients who were withdrawn from sirolimus owing to adverse effects.

    Supportive care guidelines recommend antimold prophylaxis in hematopoietic stem cell transplant (HSCT) recipients deemed to have high risk for invasive fungal infection, leading to long-term use of voriconazole after allogeneic HSCT in patients who remain immunocompromised. Voriconazole has been associated with periostitis, exostoses, and fluoride excess in patients after solid organ transplantation, HSCT, and leukemia therapy. The aims of this study were to describe the frequency and clinical presentation of patients presenting with pain and fluoride excess among allogeneic HSCT patients taking voriconazole, to identify when a plasma fluoride concentration was measured with respect to voriconazole initiation and onset of pain, and to describe the outcomes of patients with fluoride excess in the setting of HSCT. A retrospective review was conducted of all adult allogeneic HSCT patients receiving voriconazole at Mayo Clinic in Rochester, Minnesota, between January 1, 2009 and July 31, 2012. Of 242 patients included, 32 had plasma fluoride measured to explore the etiology of musculoskeletal pain. In 31 patients with fluoride measurement while on voriconazole, 29 (93.5%) had elevated levels. The median plasma fluoride was 11.1 μmol/L (range, 2.4 to 24.7). The median duration of voriconazole was 163 days (range, 2 to 1327). The median time to fluoride measurement was 128 days after voriconazole initiation (range, 28 to 692). At 1 year after the start of voriconazole after HSCT, 15.3% of patients had developed pain associated with voriconazole use and 35.7% developed pain while on voriconazole after 2 years. Of the patients with an elevated fluoride level, 22 discontinued voriconazole; pain resolved or improved in 15, stabilized in 3, and worsened in 4 patients. Ten patients continued voriconazole; pain resolved or improved in 7, was attributable to alternative causes in 2, and undefined in 1.

    Currently, acyclovir (ACV) at 1000 mg/day is widely used as prophylaxis in the early phase of hematopoietic stem cell transplant (HSCT) in Japan. However, low-dose ACV (200 mg/day) has been shown to prevent varicella zoster virus reactivation in the middle and late phases of HSCT. Therefore, in this study, we decreased the dose of ACV to 200 mg/day in the early phase after HSCT. We analyzed 93 consecutive herpes simplex virus (HSV)-seropositive patients who underwent allogeneic HSCT for the first time in our center between June 2007 and December 2011. Before August 2009, 38 patients received oral ACV at 1000 mg/day (ACV1000) until day 35 after HSCT, whereas 55 patients received oral ACV at 200 mg/day (ACV200) after September 2009. We compared the cumulative incidence of HSV infection in the 2 groups. Oral ACV was changed to intravenous administration because of intolerance in 66% and 45% of the patients in the ACV1000 and ACV200 groups, respectively (P = 0.060). The probability of severe stomatitis (Bearman grade II-III) was 76% and 60% in the ACV1000 and ACV200 groups, respectively (P = 0.12). The number of patients who developed HSV disease before day 100 after HSCT was 0 in the ACV1000 group and 2 in the ACV200 group, with a cumulative incidence of 3.6% (P = 0.43). HSV disease in the latter 2 patients was limited to the lips and tongue and was successfully treated with ACV or valacyclovir at a treatment dose. ACV at 200 mg/day appeared to be effective for preventing HSV disease in the early phase after HSCT. © 2013 John Wiley & Sons A/S.

    Thrombotic microangiopathy (TMA) is a significant complication after hematopoietic stem-cell transplantation (HSCT); however, there is little information on it following reduced-intensity cord blood transplantation (RI-CBT). We reviewed the medical records of 123 adult patients who received RI-CBT at Toranomon Hospital between January 2002 and August 2004. TMA was diagnosed in seven patients based on intestinal biopsy (n = 6) or autopsy results (n = 1). While these patients showed some clinical symptoms such as diarrhea and/or abdominal pain, mental status alterations or neurological disorders were not observed in any of them. Laboratory results were mostly normal at the onset of TMA; >2% fragmented erythrocytes (n = 1), 200 IU/dl lactic dehydrogenase (LD) (n = 4). On endoscopic examination, TMA lesions, consisting of ulcers, erosions, and diffuse exfoliation, were distributed spottily from terminal ileum to rectum. Intestinal graft-versus-host disease (GVHD) and cytomegalovirus (CMV) colitis were confirmed in five and four patients, respectively. With therapeutic measures including supportive care (n = 4), fresh frozen plasma (n = 1), and a reduction of immunosuppressive agents (n = 1), TMA improved in four patients. The present study demonstrates that intestinal TMA is a significant complication after RI-CBT. Since conventional diagnostic criteria can overlook TMA, its diagnosis requires careful examination of the gastrointestinal tract using endoscopy with biopsy.

    The aim of the study was investigate the long-term results of autologous bone marrow CD 133+ cell transplantation in patients with primary ST-Elevation Myocardial Infarction (STEMI). Methods and results: From 2006 to 2007, 26 patients with primary STEMI were included in an open randomized study. Patients were randomized to two groups: 1st - included patients underwent PCI and transplantation of autologous bone marrow CD 133+ cell (n = 10); 2nd - patients with only PCI (n = 16). Follow-up study was performed 7.70±0.42 years after STEMI and consisted in physical examination, 6-min walking test, Echo exam. Total and cardiovascular mortality in group 1 was lower (20% (n = 2) vs. 44% (n = 7), p = 0.1 and 22% (n = 2) vs. 25% (n = 4), (p=0.53), respectively). Analysis of cardiac volumetric parameters shows significant differences between groups: EDV of 100.7 ± 50.2 mL vs. 144.40±42.7 mL, ESV of 56.3 ± 37.8 mL vs. 89.7 ± 38.7 mL in 1st and 2nd groups, respectively. Data of the study showed positive effects of autologous bone marrow CD 133+ cell transplantation on the long-term survival of patients and structural status of the heart.

    BACKGROUND High-dose, post-transplantation cyclophosphamide (PTCy) to prevent graft-versus-host disease (GVHD) has improved outcomes in haploidentical (HAPLO) stem cell transplantation (SCT). However, it remains unclear whether this strategy is effective in SCT from 1-antigen human leukocyte antigen (HLA)-mismatched unrelated donors (9/10 MUD) and how the outcomes of these patients compare with those of haploidentical transplantation recipients. METHODS A parallel, 2-arm, nonrandomized phase 2 clinical trial was conducted of melphalan-based reduced-intensity conditioning with PTCy, tacrolimus, and mycophenolate mofetil to prevent GVHD in patients with high-risk hematologic malignancies who underwent HAPLO (n = 60) or 9/10 MUD (n = 46) SCT. RESULTS The 1-year overall and progression-free survival rates were 70% and 60%, respectively, in the HAPLO arm and 60% and 47%, respectively, in the 9/10 MUD arm. The day +100 cumulative incidence of grade II to IV acute GVHD and grade III to IV acute GVHD was 28% and 3%, respectively, in the HAPLO arm and 33% and 13%, respectively, in the 9/10 MUD arm. The 2-year cumulative incidence of chronic GVHD was 24% in the HAPLO arm and 19% in the 9/10 MUD arm. The 1-year cumulative incidence of nonrelapse mortality was 21% in the HAPLO arm and 31% in the 9/10 MUD arm, and the 1-year relapse rate was 19% in the HAPLO arm and 25% in the 9/10 MUD arm. CONCLUSIONS Although this was a nonrandomized study and could not serve as a direct comparison between the 2 groups, the authors conclude that PTCy-based GVHD prophylaxis is effective for both HAPLO and 9/10 MUD SCTs. Prospective randomized trials will be required to compare the efficacies of alternative donor options for patients lacking HLA-matched donors. PMID:27404668

    Full Text Available Outcomes after hematopoietic stem cell transplantation (HSCT for patients with both malignant and nonmalignant diseases have improved significantly in recent years. However, the endocrine system is highly susceptible to damage by the high-dose chemotherapy and/or irradiation used in the conditioning regimen before HSCT. Ovarian failure and subsequent infertility are frequent complications that long-term HSCT survivors and their partners face with a negative impact on their QoL. Several meta-analyses of randomized clinical trials showed that gonadotropin-releasing hormone agonist (GnRHa administration in advance of starting standard chemotherapy decreases the risk of gonadal dysfunction and infertility in cancer patients, but GnRHa use for ovarian protection in HSCT patients is not fully determined. In this review, we are discussing the potential preservation of ovarian function and fertility in pubertal girls/premenopausal women who undergo HSCT using GnRHa in parallel with conditioning chemotherapy, focusing on the current data available and making some special remarks regarding the use of GnRHa.

    Although dental treatment before hematopoietic stem cell transplantation (HSCT) is essential to prevent serious infections from oral sources, the best management plan for impacted third molar (ITM) is unclear. This study was planned to establish a management plan for ITM. Eighty-four candidates for HSCT therapy were consecutively enrolled in the prospective trial. The management plan, which was evidence based and prospectively decided, was to extract the symptomatic ITMs and to leave the asymptomatic ones untreated, regardless of their impacted position. Eighty-seven ITMs were observed in 35 patients. The ITMs were in the maxilla of 25 patients and the mandible of 28 patients. Dental extraction of 7 teeth was performed in 6 patients without complications. All of the patients received the scheduled HSCT therapy and none experienced odontogenic infection while myelosuppressed. This management plan for ITM appears to be appropriate for pre-HSCT patients. Moreover, the experienced dental provider is suggested as a necessary and valuable part of the HSCT team. Crown Copyright © 2011. Published by Mosby, Inc. All rights reserved.

    Although matched-sibling donor (MSD) hematopoietic stem-cell transplantation (HSCT) has an established role in the management of adults with acute lymphoblastic leukemia (ALL) in first complete remission (CR1), the effect of haploidentical donor (HID) HSCT as post-remission treatment for this portion of patients is not defined. Transplantation outcomes from HIDs or MSDs were compared in a disease-specific, biologically phase III randomized, multicenter study. Between July 2010 and December 2013, 210 patients with Philadelphia-negative high-risk ALL in CR1 were assigned to undergo unmanipulated HIDs (121 patients) or MSDs HSCT (89 patients) according to donor availability on an intent-to-treat (ITT) basis. Overall, 24 of the 210 patients had lost transplant eligibility. Therefore, 186 of 210 (88%) patients were finally transplanted from MSD (n = 83) or HID (n = 103). Based on the ITT principle, the 3-year disease-free survival (DFS) did not differ between HID and MSD groups [61%, 95% confidence interval (CI), 52%-70%; vs. 60%, CI, 49%-71%; P = 0.91] from CR, neither did DFS differ between the two groups (68%, CI, 58%-78%; vs. 64%, CI, 52%-76%; P = 0.56) from time of the graft, with cumulative incidence of nonrelapse mortality of 13% (CI, 7%-19%) and 11% (CI, 4%-18%; P = 0.84) and relapse rates of 18% (CI, 10%-26%) and 24% (CI, 14%-34%; P = 0.30), respectively. Haploidentical HSCT achieves outcomes similar to those of MSD-HSCT for Philadelphia-negative high-risk ALL patients in CR1. Such transplantation could be a valid alternative as post-remission treatment for high-risk ALL patients in CR1 lacking an identical donor.

    Bronchiolitis obliterans syndrome has been associated with increased morbidity and mortality after allogeneic hematopoietic stem cell transplant (HSCT). Previous studies have suggested that azithromycin may reduce the incidence of post-lung transplant bronchiolitis obliterans syndrome. To evaluate if the early administration of azithromycin can improve airflow decline-free survival after allogeneic HSCT. The ALLOZITHRO parallel-group trial conducted in 19 French academic transplant centers and involving participants who were at least 16 years old, had undergone allogeneic HSCT for a hematological malignancy, and had available pretransplant pulmonary function test results. Enrollment was from February 2014 to August 2015 with follow-up through April 26, 2017. Patients were randomly assigned to receive 3 times a week either 250 mg of azithromycin (n = 243) or placebo (n = 237) for 2 years, starting at the time of the conditioning regimen. The primary efficacy end point was airflow decline-free survival at 2 years after randomization. Main secondary end points were overall survival and bronchiolitis obliterans syndrome at 2 years. Thirteen months after enrollment, the independent data and safety monitoring board detected an unanticipated imbalance across blinded groups in the number of hematological relapses, and the treatment was stopped December 26, 2016. Among 480 randomized participants, 465 (97%) were included in the modified intention-to-treat analysis (mean age, 52 [SD, 14] years; 75 women [35%]). At the time of data cutoff, 104 patients (22%; 54 azithromycin vs 50 placebo) had experienced an airflow decline; 138 patients (30%) died (78 azithromycin vs 60 placebo). Two-year airflow decline-free survival was 32.8% (95% CI, 25.9%-41.7%) with azithromycin and 41.3% (95% CI, 34.1%-50.1%) with placebo (unadjusted hazard ratio [HR], 1.3; 95% CI, 1.02-1.70; P = .03). Of the 22 patients (5%) who experienced bronchiolitis obliterans syndrome, 15 (6%) were in

    Verrucae vulgaris in patients with severe combined immunodeficiency (SCID) after hematopoietic stem cell transplantation (HCST) can be challenging to manage. We describe two brothers with X-linked SCID who had severe, persistent verrucae that did not respond to traditional topical therapies, including liquid nitrogen, imiquimod, salicylic acid, sinecatechins, 40% urea, and 5-fluorourcil. Both brothers had full response to topical 3% cidofovir, which should be considered in recalcitrant warts in individuals with SCID after HSCT. © 2016 Wiley Periodicals, Inc.

    Full Text Available FUZHENGHUAYU Tablets have been widely used in the treatment of liver fibrosis in China. Here, we investigate the apoptotic effect of FUZHENGHUAYU Tablet in rat liver stellate cell line HSC-T6. HSC-T6 cells were incubated with control serum or drug serum from rats fed with 0.9% NaCl or FUZHENGHUAYU Tablet, respectively. Cells exposed to drug serum showed higher proportions of early and late apoptotic cells than controls. The mRNA levels of collagens I and III, TGF-β1 and α-SMA were reduced by drug serum compared to control serum. Differentially expressed mRNAs and miRNAs were analyzed by microarray and sequencing, respectively. We identified 334 differentially expressed mRNAs and also 60 GOs and two pathways related to the mRNAs. Seventy-five differentially expressed miRNAs were down-regulated by drug serum and 1963 target genes were predicted. 134 GOs up-regulated in drug serum group were linked to miRNA targets, and drug serum also regulated 43 miRNA signal transduction pathways. Protein levels were evaluated by Western blot. Drug serum down-regulated (phospho-SAPK/JNK/(SAPK/JNK and up-regulated phospho-p38/p38 ratios. The study showed that FUZHENGHUAYU Tablet induced apoptosis in rat HSC-T6 cells possibly in part by activating p38 and inhibiting SAPK/JNK.

    Transformed mycosis fungoides (MF) and Sézary syndrome (SS) are currently incurable. We studied the safety and efficacy of total skin electron beam with allogeneic hematopoietic stem-cell transplantation (HSCT) in patients with cutaneous T-cell lymphoma (CTCL). Nineteen patients with advanced CTCL (median age, 50 years; four prior therapies) underwent total skin electron beam radiation followed by allogeneic HSCT between July 2001 and July 2008. Sixteen patients were conditioned with fludarabine (125 mg/m(2)) and melphalan (140 mg/m(2)) plus thymoglobulin (for mismatched donors). Graft-versus-host disease (GVHD) prophylaxis was with tacrolimus/mini methotrexate. Eighteen patients experienced engraftment, and one died as a result of sepsis on day 16. Median time to recovery of absolute neutrophil count (ANC) was 12 days. Fifteen achieved full donor chimerism, 12 had acute GVHD, and 12 were treated for chronic GVHD. The overall intent-to-treat response was 68%, and the complete response rate was 58%. Four of six patients died in complete remission as a result of bacterial sepsis (n = 2), chronic GVHD and fungal infection (n = 1), or lung cancer (n = 1); only two died as a result of progressive disease. Eight experienced relapse in skin; five regained complete response with reduced immunosuppression or donor lymphocyte infusions. Eleven of 13 are currently in complete remissions, with median follow-up of 19 months (range, 1.3 to 8.3 years). Median overall survival has not been reached. Total skin electron beam followed by allogeneic stem-cell transplantation merits additional evaluation for a selected group of patients with refractory, advanced, cutaneous T-cell lymphoma with evidence for graft-versus-tumor effect.

    Improving treatment adherence to immunosuppressive agents could have positive effects on the morbidity and mortality of kidney transplant recipients. Our objective was to determine whether psychoeducational intervention aimed at improving treatment adherence also could improve 10-year kidney allograft survival rates. A randomized open-label study compared a group who received psychoeducational intervention (n = 55) with a control group (n = 55), with all patients being kidney transplant recipients in the Department of Nephrology and Organ Transplantation (University Hospital, Toulouse, France). Psychoeducational intervention comprised 8 weekly sessions provided by multidisciplinary teams. Patients were included between 2002 and 2003. The primary endpoint was allograft survival at 10 years (ie, by 2012). A failed allograft or death with a functioning allograft was considered an event. Mean overall allograft survival rate at 10 years was 78.2% (95% confidence interval, 70.5-25.3). In the control group, 48 patients (43.6%) still had a functioning graft at 10 years versus 38 patients (34.5%) in the psychoeducational intervention group (P = .02). However, a log-rank test did not find any significant difference in allograft survival between the groups (P = .06). In multivariate analyses (Cox model), no factor was significantly associated with allograft survival at 10 years. After an initial 6-month observational adherence survey, there was no benefit to kidney allograft survival at 10 years after the psychoeducational intervention, which had aimed to improve patient adherence to treatment with immunosuppressive agents. This might be related to the fact that booster interventions are needed (eg, on a yearly basis).

    In a 24-month, multicenter, single-arm, prospective study, 56 pediatric liver transplant patients with or without basiliximab induction were converted at 1-6 months post-transplant from standard calcineurin inhibitor (CN) therapy (± mycophenolic acid), to everolimus with reduced exposure to CNI (tacrolimus n=50, cyclosporine n=6). Steroid therapy was optional. Recruitment was stopped prematurely due to high rates of PTLD, treatment-related serious infections leading to hospitalization and premature study drug discontinuation. Subsequently, patients aged <7 years reverted to local standard-of-care immunosuppression. Mean tacrolimus concentration was above or near the upper end of the maintenance target range (2-5 ng/mL) until after month 6 post-enrollment. The primary variable, mean (SD) change in eGFR from baseline to month 12 (last observation carried forward), was +6.2 (19.5) mL/min/1.73 m 2 . Two patients experienced treated biopsy-proven acute rejection. No graft losses or deaths occurred. PTLD occurred in five patients (8.9%) (3/25 [12.0%] patients <2 years, 2/31 aged 2-18 years [6.5%]). Adverse events, serious adverse events, and discontinuation due to adverse events were reported in 100.0%, 76.8%, and 44.6% of patients, respectively. In conclusion, everolimus with reduced CNI improved renal function while maintaining antirejection potency in pediatric liver transplant patients but safety outcomes suggest that patients were overimmunosuppressed. © 2017 John Wiley & Sons A/S.
