BACKGROUND: Human neutrophil antigen 3 (HNA-3) is encoded by the SLC44A2 gene. Antibodies against HNAs can cause severe, often fatal, transfusion reactions, known as transfusion-related acute lung injury, and neonatal neutropenia. We explored the 2 common HNA-3 variants in 9 ethnic populations residing in Sichuan and Yunnan provinces of China as compared to the Han population. METHODS: We genotyped for SLC44A2 (rs2288904) by polymerase chain reaction sequence-based typing among blood donors, for a total of 2206 individuals in Yunnan and 376 in Sichuan...

BACKGROUND: Hemolysis can occur in people with G6PD deficiency under oxidative stress. Acalypha indica is a tropical plant used as a medicinal plant as well as a vegetable. There are a few reported cases of Acalypha indica ingestion induced hemolysis in G6PD deficient people. All except one of them are from Sri Lanka. The information available at present (2017) about G6PD deficiency prevalence and variants of the G6PD gene among Sri Lankans is very sparse. There are no past reports on hemolytic crisis in a G6PD deficient person presenting mimicking leptospirosis...

Introduction: The practice of carboplatin dosing is not concordant among different centres and oncologists. Some clinical guidelines recommend capping of the carboplatin dose at, for example, creatinine-clearance (Crea-Cl) of 125 mL/min because of concerns of excessive toxicity. Clinical data to support such recommendations are lacking, especially in patients with seminoma. Methods: This is a retrospective analysis of acute haematotoxicity of patients with stage I seminoma treated with adjuvant carboplatin area under the curve (AUC) 7 in routine practice in two Swiss centres in 2005-2015, and a comparison of incidence and grade (according to Common Terminology Criteria for Adverse Events v4...

BACKGROUND: Thrombocytopenia and circulating dysfunctional immune cells are commonly observed in patients with cirrhosis. Platelets may form complexes with neutrophils, monocytes and T cells modulating their function. We recently reported increased frequencies of platelet-complexed neutrophils in cirrhosis with evidence of neutrophil activation upon contact with healthy platelets in vitro. Whether this occurs in vivo following platelet transfusion and contributes to systemic inflammation and endothelial activation is unknown...

Stringent complete remission (sCR) of acute myeloid leukemia is defined as normal hematopoiesis after therapy. Less sCR, including non-sCR, was introduced as insufficient blood platelet, neutrophil, or erythrocyte recovery. These latter characteristics were defined retrospectively as postremission transfusion dependency and were suggested to be of prognostic value. In the present report, we evaluated the prognostic impact of achieving sCR and non-sCR in the Danish National Acute Leukaemia Registry, including 769 patients registered with classical CR (ie, <5% blasts in the postinduction bone marrow analysis)...

Three biosimilar filgrastim products are currently available in Japan. Among these, the safety and efficacy of two imported drugs for autologous peripheral blood stem cell harvest (autoPBSCH) and autologous peripheral blood stem cell transplantation (autoPBSCT) have been studied widely; however, evidence of the safety and efficacy of domestically manufactured filgrastim is limited. Therefore, we compared the efficacy and safety of domestic biosimilar filgrastim (BF1, n=23) with those of originator filgrastim (OF, n=21) for autoPBSCH and autoPBSCT...

BACKGROUND: Although the subject of many previous studies, the importance of white blood cell (WBC) alloimmunization in granulocyte transfusion therapy has not been settled. In this study, we report the results of the effects of WBC antibodies in the RING (Resolving Infection in Neutropenia with Granulocytes) study, a randomized controlled trial comparing the efficacy of daily granulocyte transfusion therapy plus antimicrobials versus antimicrobials alone; the primary outcome results have been published previously...

Severe neutropenia-associated invasive bacterial or fungal infections are still the major cause of mortality and morbidity in children receiving cancer chemotherapy. Granulocyte transfusion therapy has been used for many years in the management of neutropenic patients with severe infections in whom the clinical condition deteriorated despite appropriate antimicrobial treatment. Transfused granulocytes can increase the recipient's blood neutrophil count and accumulation of them into the site of infection. There are some data obtained from retrospective or prospective observational studies in pediatric granulocyte transfusion therapy, but results are not conclusive...

BACKGROUND: The preoperative neutrophil-to-lymphocyte ratio (NLR) is a well-known prognostic marker for gastric cancer patients. However, the utility of the NLR in predicting short-term outcomes in gastric cancer patients remains unclear. Here, we investigated whether the preoperative NLR is a predictor of short-term outcomes in gastric cancer patients. METHODS: We retrospectively evaluated 154 consecutive gastric cancer patients. We compared the perioperative outcomes and median survival times (MSTs)...

BACKGROUND: This study was designed to investigate the effects of leukocyte filtration of autologous salvaged blood on lung function, lung inflammatory reaction, and oxidative stress reaction in elderly patients undergoing lumbar spinal surgery. MATERIALS AND METHODS: Sixty elderly patients undergoing lumbar spinal surgery were randomly divided into 2 groups: Leukocyte Filter group and Control group. Serum levels of inflammatory markers including white blood cell and polymorphonuclear count, neutrophil elastase, serum surfactant protein A, methane dicarboxylic aldehyde, superoxide dismutase, interleukin (IL)-6, IL-8, tumor necrosis factor-α, and respiratory function markers including dynamic respiratory system compliance, oxygenation index, and respiratory index were measured immediately before induction of anesthesia (T0), immediately before blood transfusion (T1), and 1 (T2), 6 (T3), and 12 hours (T4) after end of blood transfusion...

PURPOSE OF REVIEW: Hemolytic anemias caused by premature destruction of red blood cells occur in many disorders including hemoglobinopathies, autoimmune conditions, during infection or following reaction to drugs or transfusions. Recent studies which will be reviewed here have uncovered several novel mechanisms by which hemolysis can alter immunological functions and increase the risk of severe complications in hemolytic disorders. RECENT FINDINGS: Plasma-free heme can induce the formation of neutrophil extracellular traps (NETs) through reactive oxygen species signaling...

Gene therapy for sickle cell disease is limited by the yield of hematopoietic progenitor cell harvest for transduction or gene editing. We therefore performed a Phase I dose-escalation study of the hematopoietic progenitor cell mobilizing agent plerixafor to evaluate the efficacy and safety of standard dosing on peripheral blood CD34+ cell mobilization. Of 15 patients enrolled to date, only one was chronically transfused and 10 were on hydroxyurea. Of 8 patients achieving a CD34+ cell concentration >30 cells/μl, 6 were on hydroxyurea...

Tandem autologous stem cell transplantation (ASCT) improves long-term survival of platinum-refractory germ cell tumors (GCT) patients. Studies, predominantly in lymphoma, showed that CD34+ cell doses > 5.0 x 106/kg/single transplant lead to decreased resource utilization. As most GCT patients have received prior cisplatin-based treatment, collecting >10x106 CD34+ cells/kg is challenging. We analyzed the effect of CD34+ cell dose on resource utilization and outcome of in 131 GCT patients, median age 29...

OBJECTIVES: Transferrin saturation (TSAT) 20% or less is considered to represent functional iron deficiency in the context of malignant disease, phenomenon mediated through inflammatory changes of iron homeostasis. We aimed to investigate clinical and prognostic significance of low TSAT in patients with primary (PMF) and secondary myelofibrosis (SMF), malignant diseases characterized by strong inflammatory milieu. METHODS: We retrospectively analyzed 87 patients with myelofibrosis and compared TSAT with disease specific parameters...

OBJECTIVES: Transfusion-related acute lung injury is characterized by the onset of respiratory distress and acute lung injury following blood transfusion, but its pathogenesis remains poorly understood. Generally, a two-hit model is presumed to underlie transfusion-related acute lung injury with the first hit being risk factors present in the transfused patient (such as inflammation), whereas the second hit is conveyed by factors in the transfused donor blood (such as antileukocyte antibodies)...

Allogeneic hematopoietic stem cell transplantation (HSCT) can cure transfusion-dependent thalassemia (TDT). In a multicenter trial, we investigated the efficacy of reduced intensity conditioning (RIC) before unrelated donor (URD) HSCT in children with TDT. Thirty-three children (1-17 years), received marrow or cord blood (UCB) allografts. Median time to neutrophil engraftment was 13 (range, 10-25) and 24 (range, 18-49) days; platelet engraftment was 23 (range, 12-46) and 50 (range, 31-234) days after marrow and UCB respectively...

Red cell-derived microparticles (RMPs) are potential mediators of transfusion-related acute lung injury (TRALI). The aim of this study was to investigate the effects of microparticles present in red cell concentrates (RCC) on polymorphonuclear neutrophil (PMN) respiratory burst and acute lung injury (ALI) in mice. Microparticles (MPs) in RCC supernatant were quantified using flow cytometry. The priming activity of either isolated MPs or RCC supernatant toward human PMN was measured in vitro. Mice were injected with lipopolysaccharide (LPS), followed by an infusion of either isolated MPs or heat-treated RCC supernatant...
