Invasive fungal diseases are important clinical problems that are often complicated by severe illness and therefore the inability to use invasive measures to definitively diagnose the disease. Tests for a range of fungal biomarkers that do not require an invasive sample-collection procedure have been incorporated into adult clinical practice, but pediatric data and pediatric-specific recommendations for some of these diagnostic tools are lacking. In this review, we summarize the published literature and contemporary strategies for using the biomarkers galactomannan, (1→3)-β-d-glucan, Candida mannan antigen and anti-mannan antibody, and fungal polymerase chain reaction for diagnosing invasive fungal disease in children...

Considerable progress has been made in the prevention, diagnosis, and management of pediatric patients with invasive fungal disease (IFD). The reported decreasing trend in the incidence of invasive candidiasis (IC) over the past 15 years in both neonates and children has been encouraging. Nevertheless, due to the growing number of immunocompromised children at risk for IFD, this disease continues to be associated with significant morbidity and death and with increased financial burden to the health care system...

In patients with diffuse large B-cell lymphoma (DLBCL) classified as high-intermediate risk or high risk using the International Prognosis Index, the efficacy of high-dose chemotherapy combined with upfront autologous stem cell transplantation (HDT/ASCT) remains controversial in the rituximab era. In the present study, 27 patients who had been treated with HDT/ASCT in an upfront setting were retrospectively analyzed, and compared with 77 patients with similar characteristics who had received conventional chemotherapy without HDT/ASCT (the non-upfront setting)...

Atypical chronic myeloid leukemia (aCML) is a rare subtype of myelodysplastic/myeloproliferative neoplasm (MDS/MPN). Although recurrent chromosomal and genetic abnormalities are frequently observed in aCML, none are specific to this type of leukemia. The present study reported a case of aCML associated with i(X)(p10), a rare recurrent chromosomal abnormality of hematological malignancy. A 40-year-old female was referred to the Tokyo Medical and Dental University Hospital (Tokyo, Japan) due to slight leukocytosis and anemia...

Purpose Inpatient palliative care integrated with transplant care improves patients' quality of life (QOL) and symptom burden during hematopoietic stem-cell transplant (HCT). We assessed patients' mood, post-traumatic stress disorder (PTSD) symptoms, and QOL 6 months post-transplant. Methods We randomly assigned 160 patients with hematologic malignancies who underwent autologous or allogeneic HCT to inpatient palliative care integrated with transplant care (n = 81) or transplant care alone (n = 79). At baseline and 6 months post-transplant, we assessed mood, PTSD symptoms, and QOL with the Hospital Anxiety and Depression Scale and Patient Health Questionnaire, PTSD checklist, and Functional Assessment of Cancer Therapy-Bone Marrow Transplant...

Outcomes for those diagnosed with acute myeloid leukemia (AML) remain poor. It has been widely established that persistent residual leukemic burden, often referred to as measurable or minimal residual disease (MRD), after induction therapy or at the time of hematopoietic stem cell transplant (HSCT) is highly predictive for adverse clinical outcomes and can be used to identify patients likely to experience clinically evident relapse. As a result of inherent genetic and molecular heterogeneity in AML, there is no uniform method or protocol for MRD measurement to encompass all cases...

Classical bone tissue engineering involves the use of culture-expanded cells and scaffolds to produce tissue constructs for transplantation. Despite promising results, clinical adoption of these constructs has been limited due to various drawbacks, including extensive cell expansion steps, low cell survival rate upon transplantation, and the possibility of immuno-rejection. To bypass the ex vivo cell culture and transplantation process, we exploited the regenerative capacity of the host by mobilizing endogenous stem cells to the site of injury...

INTRODUCTION: Factors promoting nerve cell ingrowth are considered responsible for chronic back pain resulting from the intervertebral disc degeneration (IDD). One of the recent exploratory IDD treatments is stem cell transplantation therapy. The CD271 (low-affinity nerve growth factor receptor) has been identified as a marker of the most homogeneous mesenchymal stem cell (MSC) subset. It is capable of promoting differentiation along adipogenic, osteogenic and chondrogenic lineages and producing significantly higher levels of cytokines as compared to the total population of plastic adherence-mesenchymal stem cells (PA-MSCs)...

We prospectively evaluated a multiplex real-time PCR assay (SeptiFast, SF) in a cohort of patients undergoing allo-BMT in comparison to an in-house PCR method (IH-PCR). Overall 847 blood samples (mean 8 samples/patient) from 104 patients with haematological malignancies were analysed. The majority of patients had acute leukaemia (62%) with a mean age of 52 years (54% female). Pathogens could be detected in 91 of 847 (11%) samples by SF compared to 38 of 205 (18.5%) samples by BC, and 57 of 847 (6.7%) samples by IH-PCR...

REVIEW
R Garakani, R F Saidi
There has been ample of preclinical and animal studies showing efficacy and safety of using various cells, such as stem cells or T regulatory cells, after transplantation for tissue repair, immunosuppression or tolerance induction. However, there has been a significant progress recently using cell therapy in solid organ transplantation in small clinical trials. Recent results have been promising and using cell therapy in solid organ transplantation seems feasible and safe. However, there are more hurdles to overcome such as dose and timing of the infusions...

Chronic graft-versus-host disease (cGVHD) is a serious complication of allogeneic stem cell transplantation with few effective options available after failure of corticosteroids. B and T cells play a role in the pathophysiology of cGVHD. Ibrutinib inhibits Bruton's tyrosine kinase in B cells and interleukin-2-inducible T-cell kinase in T cells. In preclinical models, ibrutinib reduced severity of cGVHD. This multicenter, open-label study evaluated the safety and efficacy of ibrutinib in patients with active cGVHD with inadequate response to corticosteroid-containing therapies...

INTRODUCTION: High-dose chemotherapy with autologous hematopoietic stem cell transplantation (auto-HSCT) improves the outcome of patients with multiple myeloma (MM). It seems that auto-HSCT is also a feasible therapeutic option in MM dialysis-dependent (MMDD) patients. However, to perform transplantation, a sufficient number of stem cells must be collected. MATERIALS AND METHODS: Given that data on mobilization of auto-HSC efficacy and safety in dialysis-dependent patients are limited, we report data from all Polish Centers belonging to the Polish Multiple Myeloma Group...

BACKGROUND: Fat grafting frequently requires multiple treatments and thus repeated liposuction to achieve treatment goals. The purpose of this study is to evaluate whether cryopreservation of adipose tissue may facilitate future fat grafting. METHODS: Lipoaspirates were harvested from six adult females and preserved using two cryopreservation methods: 1) simple cooling to -80˚C (cryo-1); or 2) programmed cooling to -190˚C (cryo-2). Fresh fat, cryo-1 fat, and cryo-2 fat were analyzed both in vitro and in vivo...

PURPOSE OF REVIEW: Autologous stem cell transplantation (ASCT) is generally performed in the inpatient setting in its entirety. Several centers have demonstrated the feasibility of performing ASCT for myeloma in the ambulatory setting. We review the safety, cost-effectiveness, complications and outcomes of outpatient ASCT for myeloma. RECENT FINDINGS: Published studies are heterogeneous but suggest that outpatient ASCT for myeloma is cost-effective and associated with a shorter or no initial hospitalization, albeit there is a high rate of readmission for complications...

PURPOSE OF REVIEW: Primary central nervous system lymphoma (PCNSL) is a rare cancer with a somber prognosis in older patients, which it affects predominantly. Only in recent years have molecular alterations characterizing PCNSL been thoroughly described. This opens possibilities for the use of targeted therapies. Developments in imaging and biomarkers have also great potential to help clinicians faced with diagnostic and prognostic uncertainties. RECENT FINDINGS: Several biomarkers for PCNSL, such as different microRNAs, which could be tested in cerebrospinal fluid and vitreous fluid, and IL-10, which has been shown to have excellent sensitivity and specificity in the cerebrospinal fluid, have emerged in the last years...

BACKGROUND: Donor cell leukemia (DCL) occurs after allogeneic hematopoietic stem cell transplantation. Several mechanisms, including occult leukemic/preleukemic subclones in the donor graft and germline predisposition to leukemia, are proposed to be associated with DCL's molecular pathogenesis. We report a comprehensive genetic analysis of a patient with KMT2A-rearranged DCL after allogeneic bone marrow transplantation for refractory cytopenia of childhood. PROCEDURE: We performed a whole-exome sequencing of the recipient's peripheral blood before transplant and the donor's peripheral blood and the recipient's bone marrow at the time of DCL diagnosis...
