RBCs require high deformability to sustain in-vivo circulation, and impaired deformability leads to several post-transfusion adverse outcomes. Therefore, improved understanding of the interrelation between the morphological and deformability changes and the quality and viability of the stored RBCs is essential to prevent or reduce the transfusion related adverse outcomes. To support this requisite, the influence on RBC deformability due to several aspects of the storage lesion, namely, the changes in cell morphology, surface area and volume, RBC membrane biomechanics, and cytoskeletal structural integrity are explored numerically in this study. Abstract: Storage lesion is a critical issue facing transfusion treatments, and it adversely affects the quality and viability of stored red blood cells (RBCs).

  • Plasmapheresis in Sepsis-Induced Thrombotic Microangiopathy
    CASE REPORT Plasmapheresis in Sepsis-induced Thrombotic Microangiopathy: A Case Series Sushmita RS Upadhya1, Chakrapani Mahabala2, Jayesh G Kamat3, Jayakumar Jeganathan4, Sushanth Kumar5, Mayur V Prabhu6 ABSTRACT Introduction: Cytokines and granulocyte elastase produced in sepsis cleave a disintegrin and metalloprotease with thrombospondin type I motif 13 (ADAMTS13) and deplete its levels. By this mechanism, sepsis results in microangiopathic hemolytic anemia (MAHA) with thrombocytopenia. Hence, the hypothesis is that plasmapheresis may help in sepsis-induced thrombotic microangiopathy (sTMA), by removing the factors responsible for low levels of ADAMTS13. In tropical countries like India, the contribution of sepsis to intensive care unit (ICU) mortality is high; and hence, it is essential to look out for newer modalities of sepsis treatment. There is abundant literature on the use of plasmapheresis in sepsis but data on its use in sTMA are limited, thus necessitating further research in this field. Case description: This case series studies the outcomes of five patients admitted with sTMA in the ICU and attempts to evaluate the effectiveness of plasmapheresis in improving their outcomes. All patients diagnosed with sTMA and treated with plasmapheresis, between January 2016 and August 2018 at our tertiary care center, were selected for the study. The diagnosis of sepsis was based on sepsis-3 definition. Results: Four different gram-negative organisms were found to have caused MAHA, with the commonest source being either urinary tract infection (UTI) or lower respiratory tract infection. Three of five patients required hemodialysis and two had disseminated intravascular coagulation (DIC). All five had good outcome and recovered well from the acute episode post plasmapheresis.

  • Lipopolysaccharide-Induced Hemolysis Is Abolished by Inhibition of Thrombin Generation but Not Inhibition of Platelet Aggregation
    Inflammation, Vol. 42, No. 5, October 2019 ( # 2019) DOI: 10.1007/s10753-019-01038-6 ORIGINAL ARTICLE Lipopolysaccharide-Induced Hemolysis Is Abolished by Inhibition of Thrombin Generation but Not Inhibition of Platelet Aggregation Stephan Brauckmann,1,2 Katharina Effenberger-Neidnicht,2 Michael Nagel,3 Christian Mayer,3 Jürgen Peters,1 and Matthias Hartmann 1,4 Abstract—In human sepsis, hemolysis is an independent predictor of mortality, but the mech- anisms evoking hemolysis have not been fully elucidated. Therefore, we tested the hypoth- eses that (1) lipopolysaccharide (LPS)-induced hemolysis is dependent on thrombin gener- ation or platelet aggregation and (2) red cell membranes are weakened by LPS. Anesthetized male Wistar rats were subjected to LPS or vehicle for 240 min. The effects of hemostasis inhibition on LPS-induced hemolysis were investigated by use of the thrombin inhibitor argatroban or the platelet function inhibitor eptifibatide. Free hemoglobin concentration, red cell membrane stiffness and red cell morphological changes were determined by spectropho- tometry, atomic force microscopy, and light microscopy. Efficacy of argatroban and eptifibatide was assessed by rotational thrombelastometry and impedance aggregometry, respectively. LPS markedly increased free hemoglobin concentration (20.8 μmol/l ± 3.6 vs. 3.5 ± 0.3, n =6, p < 0.0001) and schistocytes, reduced red cell membrane stiffness, and induced disseminated intravascular coagulation. Inhibition of thrombin formation with argatroban abolished the increase in free hemoglobin concentration, schistocyte formation, and disseminated intravascular coagulation in LPS-treated animals. Eptifibatide had no inhibitory effect. The LPS evoked decrease of red cell stiffness that was not affected by argatroban or eptifibatide. LPS causes hemolysis, schistocyte formation, and red cell mem- brane weakening in rats.
