We report the case of a 58-year-old woman with multiple myeloma who relapsed after the first autologous peripheral blood stem cell transplantation. She was refractory to new drugs and underwent a haploidentical allogeneic hematopoietic stem cell transplantation (haplo-HSCT) by administering post-transplantation cyclophosphamide (PTCy) after the second autologous peripheral blood stem cell transplantation. Neutrophil and platelet engraftment were achieved on days 22 and 55, respectively. Grade II cutaneous acute graft-versus-host disease was observed, which was resolved by systemic steroid treatment. selleckchem Post-transplant bone marrow examination confirmed donor chimerism replacement and immunophenotypic complete response, and the patient is alive and disease-free. Although haplo-HSCT using PTCy for multiple myeloma has not been reported in Japan, it could be performed safely. Here, we report our results with literature review.A 67-year-old man was diagnosed with a submucosal primary gastric T-cell lymphoma (PGTL) via upper gastroenteroscopy following an annual health check-up. He received six cycles of CHOP and achieved a complete remission. However, the patient relapsed 4 months post therapy. A second remission, which was maintained for years, was achieved after surgical gastrectomy followed by adjuvant chemotherapies. Prior reports have shown that surgery combined with chemotherapies was curative for patients with newly-diagnosed PGTL. In this report, surgery combined with chemotherapies was successfully applied for early-relapsed PGTL.Preventing COVID-19 infection in pediatric patients with hematological disease and cancer is important. Thus, patients and those around them should avoid crowds, wear masks, and perform hand hygiene. It is necessary to try to prevent nosocomial infections during hospitalization. Moreover, determining COVID-19 complications and the condition of patients with hematological disease and cancer, and determining a personalized treatment strategy that prioritizes the treatment of high-risk conditions is necessary when suffering from COVID-19. However, another problem is when the patient refrains from visiting a medical institution due to the fear of contracting COVID-19 infection and becomes seriously ill. Furthermore, the lack of medical resources has affected the treatment of pediatric patients with hematological disease and cancer (e.g., delays and changes in treatment). Thus, appropriate information needs to be provided to children and their parents so that preventive measures can be taken.PCR assay cannot always detect the SARS-CoV2 virus, which might be due to differences in the sensitivities of each sampling site. Under these circumstances, immunochromatography may serve as an alternative method to detect anti-SARS-CoV-2 IgG antibodies that can demonstrate a history of infection. In patients with severe COVID-19 infection, 14 of 19 serum samples were shown to be positive, whereas 6 of 10 samples from patients with asymptomatic or mild cases were negative for IgG antibodies. Two patients with immune thrombocytopenia, who were treated with prednisolone, experienced aggressive behavior of COVID-19-related respiratory failure and eventually died. Patients who were before an achievement of remission and those who received steroid-based chemotherapy possessed a higher risk of death, and more deaths were observed in patients with lymphoid malignancies including lymphoma and myeloma compared with those with myeloid malignancies. As for daily medical care in hematological department, a stricter cohorting strategy using repeat PCR tests or isolation to a private room should be adopted in order to prevent viral spread to the environment.Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread worldwide and was classified as a pandemic by the World Health Organization in March 2020. However, its clinical manifestations and optimal management in immunosuppressed patients, including recipients of hematopoietic stem cell transplantation (HSCT), are unknown. There have been some international guidelines for the management of COVID-19 in HSCT recipients. In this issue, we describe the Japanese real-world clinical condition and careful points, explaining those international guidelines.The novel coronavirus (COVID-19) pandemic has affected all aspects of human life worldwide. Under this situation, the American Society of Hematology and European Hematology Association have provided resources and recommendations for the management of hematologic diseases during the COVID-19 pandemic. This review aims to summarize these recommendations and provide helpful, accurate, and up-to-date information for Japanese hematologists.Abdominal aortic aneurysm (AAA) is a chronic inflammatory degenerative aortic disease, which particularly affects older people. Nucleotide-binding oligomerization domain-like receptor family protein 3 (NLRP3) inflammasome is a multi-protein complex and mediates inflammatory responses by activating caspase 1 for processing premature interleukin (IL)-1β and IL-18. In this review, we first summarize the principle of NLRP3 inflammasome activation and the functionally distinct classes of small molecule NLRP3 inflammasome inhibitors. Next, we provide a comprehensive literature review on the expression of NLRP3 inflammasome effector mediators (IL-1β and IL-18) and components (caspase 1, apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) and NLRP3) in clinical and experimental AAAs. Finally, we discuss the influence of genetic deficiency or pharmacological inhibition of individual effector mediators and components of NLRP3 inflammasome on experimental AAAs. Accumulating clinical and experimental evidence suggests that NLRP3 inflammasome may be a promise therapeutic target for developing pharmacological strategies for clinical AAA management.A questionnaire on COVID-19-related thrombosis in patients hospitalized before Aug 31, 2020, was sent to 399 hospitals throughout Japan. Responses were received from 111 (27.8%) with information on 6,202 COVID-19 patients. Of these, 333 and 56 required ventilation or extracorporeal membrane oxygenation (ECMO), respectively, and 212 died (3.4%). D-dimer levels were measured in 75.0% of the patients, revealing that 9.2% and 7.6% exhibited D-dimer increases of 3-8-fold and ≥8-fold the reference value, respectively. Thrombotic events occurred in 108 patients (1.86% of the 5,807 patients with available data) including symptomatic cerebral infarction in 24, myocardial infarction in 7, deep vein thrombosis in 41, pulmonary thromboembolism in 30, and other thrombotic events in 22. Some patients developed multiple thrombotic events. Thrombosis occurred in 32 patients with mild or moderate COVID-19 severity (0.59% of those with data available) and in 52 patients on ventilation or ECMO (13.5% of severe patients for whom data were available).
