Transfusion and Apheresis Science

INTRODUCTION: Due to their low frequency, there is little information on the molecular pathologies of rare bleeding disorders (RBD). Therefore, this study aimed to analyze the molecular and clinical profiles of patients with RBD. METHODS: A retrospective single-center study was conducted among patients with factor (F) II, FVII, FX, and FXIII deficiencies between March 20, 2000, and June 31, 2023. Data on patient demographics, genetic analysis, and laboratory results were documented for all patients...

Emergent Red Blood Cell (RBC) exchange is indicated in sickle cell disease (SCD) patients with severe acute chest syndrome. However, fully matched RBC units may not be available for patients with multiple RBC antibodies. Intravenous immunoglobulin (IVIG) and steroids were reported for preventing potential delayed hemolytic transfusion reaction (HTR) in simple transfusion of antigen-positive RBCs. We investigated the efficacy and safety of IVIG and steroids in two SCD patients presented with acute chest syndrome receiving RBC exchange with multiple incompatible units...

Delayed hemolytic transfusion reaction (DHTR) and hyperhemolysis syndrome (HHS) are both complications of red blood cell transfusions in patients with sickle cell disease.Clinically, both present with hemolysis and can be difficult to differentiate. Hemoglobin electrophoresis may aid in the diagnosis. Herein we describe a case in which a patient with hemoglobin SC disease presented with features of severe hemolysis several days after initiation of red blood cell exchange. Increase in reticulocyte count and complete absence of hemoglobin A on electrophoresis during this event supported the diagnosis of severe DHTR, indicating a rapid and selective destruction of the transfused red blood cells...

INTRODUCTION: Therapeutic plasma exchange (TPE), with solvent/detergent (S/D)-treated plasma as replacement fluid, is an extracorporeal blood purification technique with major impact on both coagulation and lipids. Our previous in vitro study showed that S/D-plasma enhances thrombin generation by lowering intact protein S (PS) levels. AIMS: To evaluate the impact of altered lipid balance on coagulation phenotype during heparin-anticoagulated TPE with S/D-plasma, and to investigate whether the lowered intact PS levels with concomitant procoagulant phenotype, are recapitulated in vivo...

BACKGROUND AND OBJECTIVES: Transfusion safety may be becoming dependent on the financial resources made available for transfusion structures and may vary between high-income countries (HIC) and low-to-middle-income countries (LMIC). To assess whether there is a difference in the reported TR between these two groups of countries, we examined TR reported in Tunis the capital of Tunisia, a LMIC, and compared their frequency with reported TR in HIC. MATERIALS AND METHODS: Data of TR were collected from transfusion incident report (TIR) forms declared by healthcare facilities in Tunis between 2015 and 2019...

BACKGROUND: Pain is a side effect of Granulocyte-Colony Stimulating Factor (G-CSF) administration. This prospective study investigates various aspects including pain perception occurring in Peripheral Blood Stem Cell (PBSC) donors. MATERIALS AND METHODS: Related and unrelated PBSC donors were prospectively studied. Donors recorded pain symptoms during the four-day period of G-CSF administration using the McGill Pain Questionnaire, a Visual Analog Scale and a pain diary...

INTRODUCTION: The Institute of Hematology and Transfusion Medicine (IHTM) in Warsaw has produced autologous serum eye drops (ASEDs) for the treatment of Dry Eye Syndrome (DES) since 1991. In 2019, IHTM introduced allogeneic tears (alloSEDs) for patients on long-term treatment. MATERIALS AND METHODS: 114 patients who applied alloSEDs were included in the study.They were asked to complete the OSDI questionnaire before and after using ASEDs and 100 units of alloSEDs drops from each donation...

Hepatic sinusoidal obstruction syndrome (SOS) is an illness with serious life effects that develops after hematopoietic stem cell transplantation (HSCT). We investigated the risk factors and clinical features of hepatic SOS in children following HSCT in 210 children who underwent allogeneic or autologous HSCT between 2009 and 2021 were analyzed in the context of SOS. The syndrome developed in 22 (10.4%) patients:frequently in neuroblastoma [24% (5/21)], hemophagocytic lymphohistiocytosis [57% (4/7)], and thalassemia major [22% (7/31)]...

BACKGROUND: Blood transfusion necessity in neurosurgery varies based on surgical type, blood loss, and patient anemia. Leukocytes in red blood cells (RBCs) component release pro-inflammatory cytokines during storage, contributing to transfusion-related immunomodulation (TRIM). Our aim was to examine the impact of the leukocyte content in transfused PRBCs on patients undergoing neurosurgery for meningioma tumours. STUDY DESIGN AND METHODS: This prospective randomized controlled trial conducted from 2018 to 2020 by dividing patients randomly into non-leukoreduced (NLR) (n = 65) and leuko-reduced (LR) (n = 65) groups based on PRBCs received during surgery and hospital stay...

Granulocytes are the most important cells for host defense during infections. Granulocyte suspension transfusions (GTx) may be given as additional treatment in severely neutropenic patients with life-threatening infections when antimicrobial therapy is inadequate. The aim of this study was to evaluate the effectiveness and safety of GTx for the treatment of children with hemato-oncological disease, febrile neutropenia and serious life-threatening infections. Patients who underwent GTx between July 2020 and September 2022 were evaluated retrospectively...

BACKGROUND & OBJECTIVES: The primary objective of this observational study was to perform an exhaustive description concerning patients receiving extracorporeal photopheresis (ECP) as second line treatment after steroid resistance for either acute or chronic GVHD following allo-HCT, secondary objectives were to evaluate the efficacy and long-term outcomes. STUDY DESIGN: A total of 106 patients were included, 65 (61%) males and 41 (39%) females with a median age at transplantation of 52 years (range: 20-67)...

Kratom is an herbal supplement which is used for its stimulating properties and pain reduction due to interaction with opioid receptors. Kratom overdose may cause fatality. A 56-year-old man was admitted to the emergency department with severe jaundice and liver failure. His total bilirubin reached at 70.6 mg/dL, but extensive workup did not show any liver mass. Family informed that the patient was taking Kratom. Plasma exchange was suggested as an unconventional therapy and consent from the patient was obtained because this procedure has never been performed to treat Kratom toxicity before...

INTRODUCTION: Anemia occurs before and after kidney transplantation. Determining the impact of perioperative transfusion on post-transplant outcomes can help determine best management of anemia. PROJECT AIM: The current study aims to describe clinical outcomes associated with packed red blood cell transfusions in the peri-operative management of anemia after transplantation. DESIGN: This was a single-center, retrospective study of adult kidney recipients with anemia at the time of transplantation...

OBJECTIVE: The study aimed to determine nurses' self-efficacy levels for safe transfusion of blood and blood components. METHOD: The design of this study is descriptive and cross-sectional. Before starting the study, ethics committee approval and institution approval was obtained. The participants were informed about the purpose of the study, and their written consent was obtained. The research was conducted between the dates 01 March 2022 and 01 May 2022, a private hospital in Turkey...

The history of blood transfusion has been dominated by the search for compatibility for species specificity, the search for how to transfer blood from one individual into another or infuse. Safety has become a major issue since it became clear that blood was not only able to allow mystical miracles to take place but could transmit infectious diseases. The science behind these ideas reflects observation, a thinking and exchange of knowledge and skills, originally documented in reports or case studies of what has happened and was observed, and peer presented - knowledge economy...
