Fatal posterior reversible encephalopathy syndrome after blood transfusion in a patient with myelodysplastic syndromes.

Background: Posterior reversible encephalopathy syndrome (PRES) is known as a transfusion-related complication with typically favorable prognosis and no report fatalities. Pathological evaluation of PRES is also scarce.

Case Report: An 88-year-old female with myelodysplastic syndromes (MDS) attended our hospital because of a compression fracture and chronic heart failure with chronic anemia.

Procalcitonin elevation in febrile recipients during pre-transplant conditioning with anti-thymocyte globulin.

Infection is a major contributor to non-relapse mortality in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Detecting infectious diseases in febrile patients during pretransplant conditioning is crucial for subsequent transplant success. Procalcitonin (PCT) is an auxiliary diagnostic marker of severe bacterial infections and has been proposed as a useful predictor of infection in patients undergoing allo-HSCT.

[Safety and feasibility of outpatient management in relapsed/refractory lymphoma treated with pegfilgrastim after multi-agent salvage therapy: a single-center, open-label, non-randomized, prospective interventional study].

Objective: We sought to assess the safety and feasibility of outpatient management in Japanese patients with relapsed/refractory lymphoma who had received pegfilgrastim after salvage therapy.

Method: This was a single-center, open-label, non-randomized, prospective interventional analysis. Patients were completely hospitalized for cycle 1 of chemotherapy.

Outcomes of allogeneic stem cell transplantation for patients with hematologic diseases ≥60 years old.

Hematologic diseases frequently affect people >60 years old, and allogeneic stem cell transplantation (allo-SCT) is a potentially curative treatment for these patients. Although several multicenter studies proposed the risk assessment of allo-SCT for the elderly, they receive different treatments and management at each facility. Therefore, accumulating data from institutions that exhibit relatively the same treatment policy and patient care is important.

Clinical impact of comprehensive geriatric assessment in patients aged 80 years and older with diffuse large B-cell lymphoma receiving rituximab-mini-CHOP: a single-institute retrospective study.

Purpose: Comprehensive geriatric assessment (CGA) has been used to help identify elderly patients with diffuse large B-cell lymphoma (DLBCL) who were suitable for rituximab combined with CHOP therapy (cyclophosphamide, Adriamycin, vincristine, and prednisolone), but there are few reports of CGA for elderly patients with DLBCL who received R-mini-CHOP.

Methods: We retrospectively analyzed the risk factors for outcomes among 142 patients aged 80 years and older (≤ 85 years, n = 102; > 85 years, n = 40) with DLBCL who received R-mini-CHOP at 4-week intervals at our institute between 2008 and 2019. We performed a comparison between CGA and treatment outcomes.

AIMS65 predicts prognosis of patients with duodenal ulcer bleeding; a comparison with other risk-scoring systems.

Background And Aim: Duodenal ulcer bleeding has a higher risk of mortality than bleeding from other portions of the gastrointestinal tract. AIMS65 is an effective risk-scoring system to predict prognosis of upper gastrointestinal bleeding and can be easily calculated without endoscopic findings. In this study, we investigate the usefulness of AIMS65 to predict prognosis of patients with duodenal ulcer bleeding.

Correction to: Measurable residual disease after the first consolidation predicts the outcomes of patients with acute promyelocytic leukemia treated with all-trans retinoic acid and chemotherapy.

In the original publication of the article, the "CNS involvement" in the last row under the column "Total N=50" has been published incorrectly. The correct Table 1 is given in this correction.

Measurable residual disease after the first consolidation predicts the outcomes of patients with acute promyelocytic leukemia treated with all-trans retinoic acid and chemotherapy.

We stratified patients with newly diagnosed acute promyelocytic leukemia (APL) according to a white blood cell (WBC) count of ≥ 3 × 10/L (high risk) or < 3 × 10/L (low risk) before administering risk-adapted chemotherapy in combination with all-trans retinoic acid (ATRA). In total, 27 low-risk and 23 high-risk patients were assigned to receive induction and three courses of consolidation with ATRA and anthracycline, followed by 2-year maintenance regimen. High-risk group additionally received cytarabine during 1st consolidation and another one-shot idarubicin treatment during 3rd consolidation.

Tyrosine kinase inhibitors induce alternative spliced BCR-ABL variant via inhibition of RNA polymerase II on genomic BCR-ABL.

To elucidate dynamic changes in native BCR-ABL and alternatively spliced tyrosine kinase inhibitor (TKI)-resistant but function-dead BCR-ABL variant, following commencement or discontinuation of TKI therapy, each transcript was serially quantified in patients with chronic myeloid leukemia (CML) by deep sequencing. Because both transcripts were amplified together using conventional PCR system for measuring International Scale (IS), deep sequencing method was used for quantifying such BCR-ABL variants. At the initial diagnosis, 7 of 9 patients presented a small fraction of cells possessing BCR-ABL , accounting for 0.

[Hairy cell leukemia complicated by bone marrow necrosis following cladribine administration].

Classic hairy cell leukemia (classic HCL) is a rare disease associated with indolent mature B-cell lymphoma. A 50-year-old man presented with pancytopenia for 3 years and was diagnosed with classic HCL because his lymphoid cells showed a hairy morphology with oval nuclei and indistinct nucleoli both in the peripheral blood and bone marrow (BM) smears. Flow cytometric analysis revealed that these cells expressed CD11c, CD25, and CD103, and the Sanger sequence method detected BRAF V600E mutation.

Bilateral Adrenal Hemorrhage in a Patient with Antiphospholipid Syndrome during Chronic Graft-versus-host Disease.

We present the case of a 56-year-old man with an upper respiratory infection followed by fatigue, hypotension, and hyponatremia. Bilateral adrenal hemorrhage was confirmed, based on T2-weighted magnetic resonance imaging. The patient had previously undergone allogeneic hematopoietic stem cell transplantation and had been diagnosed with antiphospholipid syndrome (APS) during the development of chronic graft-versus-host disease.

Comparative analysis of pulmonary hypertension in patients treated with imatinib, nilotinib and dasatinib.

Pulmonary hypertension (PH) is a rare, but life-threatening, adverse event in patients treated with tyrosine kinase inhibitors (TKIs), such as dasatinib, but has not been fully evaluated in patients treated with imatinib or nilotinib. We used echocardiography to noninvasively assess the incidence of PH in 105 patients with chronic myeloid leukaemia (CML) treated with imatinib (n = 37), nilotinib (n = 30) or dasatinib (n = 38). The mean triscupid regurgitation peak gradient (TRPG), which reflects pulmonary arterial pressure, was 22·7 mmHg in the imatinib group, 23·1 mmHg in the nilotinib group and 23·4 mmHg for dasatinib group.
