BACKGROUND: The diagnosis of paroxysmal nocturnal hemoglobinuria (PNH) relies on flow cytometric demonstration of loss of glycosyl-phosphatidyl inositol (GPI)-anchored proteins from red blood cells (RBC) and white blood cells (WBC). High-sensitivity multiparameter assays have been developed to detect loss of GPI-linked structures on PNH neutrophils and monocytes. High-sensitivity assays to detect PNH phenotypes in RBCs have also been developed that rely on the loss of GPI-linked CD59 on CD235a-gated mature RBCs...

Transfusion-related acute lung injury (TRALI) is a life-threatening complication of acute respiratory distress occurring within 6 hours of blood transfusion. TRALI is one of the leading causes of transfusion-related fatalities and specific therapies are unavailable. Neutrophils are recognized as the major pathogenic cells, whereas T regulatory cells and dendritic cells appear to be important for protection against TRALI. The pathogenesis, however, is complex and incompletely understood. It is frequently postulated that the complement system plays an important role in the TRALI pathogenesis...

AIM: Aortic dissection (AD) is a devastating disease with rapid progression and high mortality, while the initiation mechanism of AD is far from clear. MAIN METHODS: AD was established by feeding mice with β-aminopropionitrile in the diet and usage of angiotensin II (AngII) to trigger the rupture of aorta. LysMiDTR mice were constructed by crossing of LysM-Cre mice with ROSA26iDTR mice and characterized by diphtheria toxin receptor (DTR) expression in monocytes/macrophages specifically...

OBJECTIVES: Hepatic ischemia-reperfusion injury and transfusion of red blood cells in liver surgery are wellknown risk factors to induce acute tubular injury. Transfusion of stored red blood cells may affect hepatic ischemia-reperfusion injury-induced acute tubular injury. Here, we hypothesized whether preischemic (due to increased severity of hepatic injury) and postischemic (due to renal uptake of free heme and iron) transfusion of stored red blood cells may potentiate acute tubular injury in rats subjected to hepatic ischemia-reperfusion injury...

Purpose: IL-33 is associated with invasion, proliferation, and metastasis of various cancers. The trophoblastic cells of placenta previa accreta (PPA) invade into the myometrium in a similar way to the invasion of cancers. We studied the role of IL-33 in PPA and also aimed to investigate its relation with adverse maternal outcome in this placental disorder. Methods: A total of 87 pregnant patients were enrolled in this prospective case-control study [27 with PPA, 30 with placenta previa totalis (PPT; nonadherent placenta previa) and 30 controls]...

Tumor-associated immune-suppressive neutrophils are prevalent in various cancers, including colorectal cancer. However, mechanisms of immune-suppressive neutrophils are not well understood. We report that a key innate suppressor, IRAK-M (interleukin-1 receptor-associated kinase M), is critically involved in the establishment of immune-suppressive neutrophils. In contrast to the wild-type (WT) neutrophils exhibiting immune-suppressive signatures of CD11bhigh PD-L1high CD80low , IRAK-M-deficient neutrophils are rewired with reduced levels of inhibitory molecules PD-L1 and CD11b, as well as enhanced expression of stimulatory molecules CD80 and CD40...

In blood banks, platelets are stored until 7 days after a pathogen reduction technology (PRT) treatment, Mirasol® (vitamin B2 plus UVB light) in the present case. The storage time under these conditions may have an impact on platelets and their releasate leading to potential adverse reactions following transfusion to patients. The aim of this study was to analyze the proteome of extracellular vesicles generated by platelets at different storage days (2 and 7) to gain deeper information on the platelet concentrates state at those moments...

Granulocyte transfusion (GTX) is a therapeutic option for severe bacterial or fungal infection in patients with sustained neutropenia after chemotherapy or stem cell transplantation. However, high molecular weight hydroxyethyl starch (HES), which has been used for selective sedimentation of red blood cells during apheresis, is not easily available in many countries including Japan. In this study, we evaluated the efficiency of granulocyte collection using medium molecular weight HES (130 kDa) in combination with the Spectra Optia apheresis system...

High-dose chemotherapy (HDT) followed by autologous hematopoietic stem cell transplantation (ASCT) is widely used in patients with malignant lymphomas. In Europe over 8,000 ASCTs for lymphoma were performed out of a total of 40,000 transplants according to the European Bone Marrow Transplant (EBMT) activity survey in 2017. ASCT is considered the standard treatment for eligible patients failing to achieve remission after first line chemotherapy or patients with relapsed or refractory lymphomas, including classical Hodkin's lymphoma, diffuse large B-cell lymphoma, mantle cell lymphoma, and follicular lymphoma, as well as consolidation therapy in first remission in mantle cell lymphoma...

Gray platelet syndrome (GPS) is an inherited disorder. Patients harboring GPS have thrombocytopenia with large platelets lacking α-granules. A long-term complication is myelofibrosis with pancytopenia. Hematopoietic stem cell transplant (HSCT) could be a curative treatment. We report a male GPS patient with severe pancytopenia, splenomegaly and a secondary myelofibrosis needing red blood cells transfusion. He received an HSCT from a 10/10 matched HLA-unrelated donor after a myeloablative conditioning regimen...

BACKGROUND: Aplastic anaemia is a rare, life-threatening condition, characterised by pancytopenia with hypocellular bone marrow. Haematopoietic stem cells and most progenitor cells express thrombopoietin receptor (c-MPL). Romiplostim is a peptibody with c-MPL agonist activity that stimulates endogenous thrombopoietin production and leads to promoting the proliferation and differentiation of megakaryocytes in the bone marrow. In this phase 2 trial we aimed to assess the activity and safety of romiplostim in patients with aplastic anaemia who were previously treated with immunosuppressive therapy...

Background: The grading systems for intra-abdominal sepsis (IAS) are not employed commonly in clinical practice because they are too complicated or too specific. We propose to grade IAS with a simple grading system: the TNM system, which is an acronym borrowed from cancer staging, where T indicates Temperature, N indicates Neutrophils, and M indicates Multiple organ failure (MOF). The aim of this prospective observational study is to assess the predictive value of the TNM score on deaths of patients with complicated IAS...
