INTRODUCTION: Acute pancreatitis (AP) is one of the most common diseases involving necrotic inflammation. Bone marrow mesenchymal stem cells (BMMSCs) have the potential of multi-directional differentiation and self-renewal for tissue repair. It remains less clear if granulocyte colony-stimulating factor (G-CSF) can improve the therapeutic effect of BMMSC transplant in AP. Therefore, we explored this issue in a rat model of experimental AP. RESULTS: Transplanted PKH26-positive BMMSCs were present in the injured pancreatic tissue, with some cells co-expressed pancreatic cellular markers, including Pax-4, Ngn3 and Nkx-6...

Magnusiomyces capitatus (previously known as Geotrichum capitatum or Blastoschizomyces capitatus or Trichosporon capitatum) is a rare cause of fungal infection in immunocompromised patients. Most of these cases (87%) have been reported from the Mediterranean region, as it is extremely rare to recognize it in other regions. Here we report a first case of disseminated M. capitatus infection in Slovakia. The patient - 19 year old woman with myelodysplastic syndrome was diagnosed with M. capitatus fungemia after allogeneic stem cell transplantation...

A 29-year-old male with transfusion-dependent β-thalassemia major (β-TM), splenectomized and on chelation therapy with deferiprone (DFP or L1) due to heart and liver hemosiderosis, presented with high fever and agranulocytosis. Deferiprone was discontinued and a broad spectrum antibiotic therapy was started intravenously. The patient remained febrile and showed no recovery of neutrophil count even after the initiation of granulocyte colony-stimulation factor (G-CSF). After 12 days at the hospital, he developed respiratory failure and was transferred to the intensive care unit (ICU) where he developed multi-organ failure and died 3 days later...

REVIEW
Kamille A West, Juan Gea-Banacloche, David Stroncek, Sameer S Kadri
Granulocyte transfusions have a long history of being used in patients with neutropenia or neutrophil dysfunction to prevent and treat invasive fungal infections. However, there are limited and conflicting data concerning its clinical effectiveness, considerable variations in current granulocyte transfusion practices, and uncertainties about its benefit as an adjunct to modern antifungal therapy. In this review, we provide an overview on granulocyte transfusions and summarize the evidence on their role in the prevention and treatment of invasive fungal infections...

Allogeneic haematopoietic stem cell transplantation is curative for severe aplastic anaemia (SAA) unresponsive to immunosuppressive therapy. To reduce chronic graft-versus-host disease (GVHD), which occurs more frequently after peripheral blood stem cell (PBSC) transplantation compared to bone-marrow transplantation (BMT), and to prevent graft rejection, we developed a novel partial T-cell depleted transplant that infuses high numbers of granulocyte colony-stimulating factor-mobilized CD34(+) selected PBSCs combined with a BMT-equivalent dose of non-mobilized donor T-cells...

BACKGROUND: Different polymerase chain reaction (PCR) techniques for human neutrophil antigens (HNA) genotyping have been implemented to diagnose the clinical conditions of patients with alloimmune neutropenia, febrile non-hemolytic transfusion reactions, and transfusion-related acute lung injury and to provide effective HNAmatched granulocyte transfusions. The present study aimed to develop an in-house multiplex-PCR for HNA-1, -3, -4, and -5 genotyping in the Thai population. METHODS: Altogether, 500 DNA samples obtained from unrelated, healthy Thai blood donors at the National Blood Centre, Thai Red Cross Society, Bangkok, Thailand were included...

Plasma administration has been recommended in calves older than 48h with failure of passive immunity (FPI) to provide immunity consistent with adequate colostral ingestion. However, the protective serum immunoglobulin G (IgG) concentrations (≥1000mg/dL) of plasma derived IgG only lasts up to 12h. In addition to IgG, maternally derived colostral cells also confer immunity. The objective of the study was to determine the effect of intravenous plasma transfusion on granulocyte and monocyte oxidative and phagocytic activity in calves with FPI...

BACKGROUND AND OBJECTIVES: Buffy coat-derived granulocytes have been described as an alternative to the apheresis product from donors pretreated with dexamethasone and granulocyte colony-stimulating factor (G-CSF). The latter is - dependent on the local and national settings - obtained following a demanding and time-consuming procedure, which is undesirable in critically ill septic patients. In contrast, buffy coat-derived products have a large volume and are often heavily contaminated with red cells and platelets...

A survey was conducted to investigate the standard of care for multiple myeloma in Germany, in order to clarify the status of implementation of international and national treatment guidelines. In addition, the changes in disease management over time were investigated by comparison with surveys conducted in 2008 and 2009. The survey captured a representative sample of 478 myeloma patients with a mean age of 67.9 years across various stages of the disease. Diagnostic approaches, prognostic aspects and treatment decisions were evaluated based on a survey conducted in 2011 in 58 representative centres in Germany, including university and non-university hospitals and office-based haematologists...

BACKGROUND: Granulocyte transfusion (GTX) is a potential approach to correcting neutropenia and relieving the increased risk of infection in patients who are refractory to antibiotics. To mobilize enough granulocytes for transfusion, healthy donors are premedicated with granulocyte-colony-stimulating factor (G-CSF) and dexamethasone. Granulocytes have a short circulatory half-life. Consequently, patients need to receive GTX every other day to keep circulating granulocyte counts at an acceptable level...

Severely injured burn patients receive multiple blood transfusions for anemia of critical illness despite the adverse consequences. One limiting factor to consider alternate treatment strategies is the lack of a reliable test platform to study molecular mechanisms of impaired erythropoiesis. This study illustrates how conditions resulting in a high catecholamine microenvironment such as burns can instigate myelo-erythroid reprioritization influenced by β-adrenergic stimulation leading to anemia. In a mouse model of scald burn injury, we observed, along with a threefold increase in bone marrow LSK cells (lin(neg) Sca1(+)cKit(+)), that the myeloid shift is accompanied with a significant reduction in megakaryocyte erythrocyte progenitors (MEPs)...

Jinlin Jiang, Chen-Yuan Kao, Eleftherios T Papoutsakis
Megakaryocytic microparticles (MkMPs), the most abundant MPs in circulation, can induce the differentiation of hematopoietic stem and progenitor cells (HSPCs) into functional megakaryocytes. This MkMP capability could be explored for applications in transfusion medicine but also for delivery of nucleic acids and other molecules to HSPCs for targeted molecular therapy. Understanding how MkMPs target, deliver cargo and alter the fate of HSPCs is important for exploring such applications. We show that MkMPs, which are distinct from Mk exosomes (MkExos), target HSPCs with high specificity since they have no effect on other ontologically or physiologically related cells, namely mesenchymal stem cells, endothelial cells or granulocytes...

Derivative (5;19)(p10;q10) [der(5;19)(p10;q10)] is a rare chromosomal abnormality in myelodysplastic syndrome (MDS), and is genetically similar to deletion 5q [del(5q)]. However, MDS with der(5;19)(p10;q10) and 5q- syndrome are generally characterized as distinct subtypes. Here, we report a case of a patient with 5q- syndrome-like features as the first manifestation of MDS with der(5; 19)(p10;q10). A 59-year-old woman was admitted to our hospital for anemia without leukopenia and thrombocytopenia. She had received chemotherapy comprising carboplatin and docetaxel for endometrial cancer eight years before...

The C/EBPE gene, located in 14q11.2, encodes for a B/zip-type transcription factor. The C/EBPɛ is involved in terminal differentiation and functional maturity of granulocyte progenitor cells and in cell apoptosis during myeloid differentiation. A C/EBPE gene has recently been described as a candidate gene involved in clinical variability of β-thalassemia (β-thal). In this study, the C/EBPE gene was sequenced in 146 subjects divided into the severe type of β-thal major (β-TM) and moderate type of β-thal intermedia (β-TI), and a control group...

BACKGROUND: To reduce the risk of transfusion-associated acute lung injury (TRALI), a high number of plasma donors were tested for human leukocyte antigen (HLA) and human neutrophil antigen (HNA) antibodies. For HNA antibody detection, the gold standard is a combination of the granulocyte immunofluorescence test (GIFT) and the granulocyte agglutination test (GAT). However, these tests are not suitable for a high-throughput of samples. STUDY DESIGN AND METHODS: To evaluate the new generation of the LABScreen MULTI assay (One Lambda, Inc...

Podostroma cornu-damae is a rare, deadly fungus. However, it can be easily mistaken for antler Ganoderma lucidum. In this case report, two patients made tea with the fungus and drank it over a 2-week period. Both patients presented with bicytopenia, and one patient had desquamation of the palms and soles. Both were treated with prophylactic antibiotics and granulocyte colony-stimulating factor. One patient was admitted to the intensive care unit and received a platelet transfusion. Both patients were discharged without complications...
