BACKGROUND: Cardiac surgery for myelodysplastic syndrome (MDS) patients is challenging because anemia and neutropenia develop as a result of the syndrome, leading to infection and bleeding tendency during surgery. We report the case of minimally invasive mitral valve repair via a right mini-thoracotomy and perioperative use of granulocyte colony-stimulating factor (G-CSF) in a patient with MDS. CASE PRESENTATION: A 77-year-old man with myelodysplastic syndrome (MDS) was referred for surgical treatment for mitral valve regurgitation and underwent a minimally invasive mitral valve repair via a right mini-thoracotomy (MICS mitral procedure)...

Platelet transfusion refractoriness (PTR) is frequently observed after allogeneic hematopoietic cell transplantation (HCT). However, the incidence of and risk factors for PTR, and impact of PTR on transplant outcomes after cord blood transplantation (CBT) have not been fully investigated. We retrospectively analyzed 185 adult patients who received single-unit CBT in our institute. The mean 16-hour corrected count increment (CCI) for the 5,840 platelet transfusions was 3.68×109 /l. Among them, 3,196 transfusions (54...

BACKGROUND: Human neutrophil antigens (HNA) are able to provoke allo- and autoimmune antibodies which lead to reactions like autoimmune and neonatal neutropenia. However, until now no data about HNA genotype distribution in Syrian population exists. The aim of this study was to determine the HNA allele frequencies in the largest group asking for asylum in Germany since 2015. Allele frequencies were compared to data from German blood donors. Therefore, we calculated the risk of alloimmunization and associated transfusion reactions, as well as the risk of developing neonatal neutropenia for newborns of mixed race couples...

Lifetime blood transfusion experienced by major β-thalassemia patients complicated with iron overload, therefore, may lead to their tissue injury. Ultimately, free toxic iron may alter immune response via dysregulation of immune cell activity producing prolonged effector reaction. Neutrophil as one of the vital innate immune cell despite serves as the first line of defense resulting acute inflammation has a pivotal role in chronic inflammation while releasing the toxic substance that interferes biological processes...

BACKGROUND: White blood cell-associated antibodies can lead to transfusion-related acute lung injury (TRALI). Female donors with a history of pregnancies have been identified as a main cause for these antibodies. Male or female donors without a history of pregnancy are considered as safe donors. STUDY DESIGN AND METHODS: Following the identification of two TRALI cases associated with blood products from male donors, we investigated the frequency of granulocyte-specific and human leukocyte antigen (HLA) antibodies in the entire blood donor population using a high throughput automated flow-cytometry-based granulocyte immunofluorescence test (Flow-GIFT)...

Severe leukopenia, thrombocytopenia, and bi-cytopenia due to nivolumab have been reported. In this report, we present the first case of nivolumab-induced severe pancytopenia in a patient with lung adenocarcinoma. A 56-year-old Japanese man with lung adenocarcinoma received nivolumab therapy as second-line treatment. After 3 cycles of this therapy, although computed tomography (CT) showed a reduced tumor size, laboratory findings revealed pancytopenia and a bone marrow biopsy showed a severely hypoplastic marrow...

The formation of neutrophil extracellular traps (NETs) has been associated with endothelial damage and severe pulmonary dysfunction. The present study aimed to investigate whether this NETosis occurs during intraoperative blood salvage (IBS), and whether the washing procedures before re-transfusion of autologous blood could remove the NET components, including DNA, histones, and myeloperoxidase. The study was performed using blood samples from 20 patients who underwent posterior lumbar surgery at the Beijing Friendship Hospital...

Patients hospitalized with pneumonia may require packed red blood cell (RBC) transfusion during their hospital stay. Patient survival may be associated with the transfusion trigger. These patients may need a higher hemoglobin (Hb) trigger than that suggested by the AABB guidelines (7 g/dL).The objective of this study was to evaluate the association between the initial transfusion Hb trigger and in-hospital mortality.A historical cohort study of all patients hospitalized in an internal medicine ward between 2009 and 2014 with pneumonia, who received at least 1 unit of RBC, was evaluated...

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...
