AbstractPrimary graft failure can be a cause of early morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT), as it leads to a high risk of severe infections and bleeding. Splenomegaly is associated with primary graft failure in patients of myelofibrosis, but the association between splenomegaly and outcomes after HSCT in patients with myeloid malignancies has not been previously evaluated. The aim of this study was to investigate the effect of spleen volume on engraftment kinetics in patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). We enrolled 85 patients. The...

A 62-year-old man with acute myeloid leukemia, evolved from myelodysplastic syndrome after allogeneic bone marrow transplant, was admitted to the hospital because of worsening fatigue and altered level of consciousness. On arrival at the hospital, the patient was markedly fatigued and had signs of encephalopathy. He reported no fevers, chills, or diaphoresis but noted new urinary incontinence and nausea. His medical history was notable for a matched unrelated donor allogeneic hematopoietic stem cell transplant (HCT), performed 35 days previously, as well as hypertension and peripheral vascular disease.

The correlation between human T-cell leukemia virus type І (HTLV-І) infection and malignant neoplasms other than adult T-cell lymphoma (ATL) remains unknown. We analyzed the frequency of primary malignant neoplasm in HTLV-І-seropositive patients. From January 2006 to December 2016, 203 patients were diagnosed as HTLV-І-seropositive at Kansai Medical U niversity Hospital. Among them, 32 developed a primary malignant neoplasm. Their median age was 64 years old, 63% of them were male, and 69% of them were HTLV-I carriers. This group had the following distribution of ATL subtypes: 31% smoldering type, 0% chronic type, 3% a...

Authors: Jiang Y, Liu L, Wang J, Cao Z, Zhao Z Abstract Previous studies have suggested that Wilms' tumor gene-1 (WT1) may be related to a decrease in both relapse-free survival (RFS) and overall survival (OS) for patients with myelodysplastic syndrome (MDS). Therefore, we conducted a meta-analysis on the utility of WT1 as a prognostic indicator of MDS. Published reports were searched in the following databases: Cochrane Library, PubMed, Embase, and Web of Science. The meta-analysis was conducted using the Cochrane Collaboration RevMan 5.2 software. Six publications with 450 total patients met the inclusion criteri...

Conclusions: Delayed sample processing causes considerable immunohenotypic alterations, which can lead to false interpretation of the results. If delayed sample evaluation is unavoidable, markers that remain more stable over time should be considered with more weight in the diagnosis of MDS. PMID: 29666557 [PubMed - in process]

CONCLUSION: A high prevalence of iron overload in this patient population in Latin American countries indicates that a better diagnosis and management of iron overload is required in these countries. PMID: 29663858 [PubMed - as supplied by publisher]

AbstractThe myelodysplastic syndromes (MDSs) are clonal hematopoietic stem cell disorders. The International Prognostic Score System (IPSS) groups MDS in lower-risk (IPSS low and intermediate-1) and higher-risk disease (IPSS intermediate-2 and high). AML transformation is the main concern in higher-risk MDS, while anemia and transfusion dependency represent the major issues for low-risk MDS patients. Improving erythropoiesis, and eliminating fatigue and symptoms, is the main therapeutic goal for low-risk MDS patients. Around 50% of MDS patients present with anemia with an Hb level

This study aimed to investigate the development of tMNs following ASCT at the molecular level by whole-exome sequencing (WES) and targeted deep sequencing (TDS) in sequential (pre-) tMN samples. WES identified a significantly higher number of mutations in tMNs as compared with de novo myelodysplastic syndrome (MDS) (median 27 vs 12 mutations; P = .001). The mutations found in tMNs did not carry a clear aging-signature, unlike the mutations found in de novo MDS, indicating a different mutational mechanism. In some patients, tMN mutations were identified in both myeloid and T cells, suggesting that tMNs may originate from ea...

We examined the possible diagnostic and prognostic values of exosomal microRNAs in two human bone marrow failure diseases, aplastic anemia and myelodysplastic syndromes. After screening of 372 microRNAs in a discovery set (n=42) of plasma exosome samples, we constructed a custom microRNA PCR plate, including 42 microRNAs, for validation in a larger cohort (n=99), and we identified 25 differentially expressed exosomal microRNAs uniquely or frequently present in aplastic anemia and/or myelodysplastic syndromes. These microRNAs could be related to intracellular functions, such as metabolism, cell survival, and proliferation. ...
