BACKGROUND: Patients presenting with acute episodes of thrombotic microangiopathies (TMAs) require urgent access to plasma exchange (PEX). OctaplasLG, a solvent/detergent fresh-frozen plasma product that has undergone viral inactivation and prion reduction step, has been used in our institution since 2013, replacing Octaplas. STUDY DESIGN AND METHODS: We prospectively reviewed 981 PEX procedures where OctaplasLG was the replacement fluid in 90 patients admitted acutely with a TMA presentation within our institution from January 1, 2013, to December 31, 2015...

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) is a rare but serious disease caused by autoantibody-mediated deficiency in von Willebrand factor (VWF) cleaving protease, ADAMTS-13. The primary acute treatment is therapeutic plasma exchange (TPE). However, some patients can develop allergic/anaphylactic reactions to the replacement (i.e., donor) plasma over time. Two potential treatment strategies for patients with TTP who demonstrate severe allergic reactions to plasma used for exchange were examined...

OBJECTIVES: Factor V (FV) plays an important role in coagulation. As no purified concentrate is available to restore critical FV levels, the main blood product used to replace FV is plasma. The aim of the present in vitro study was to compare the efficacy of the different available plasma products on the reversal of moderate and severe FV deficiency as assessed by ROTEM® and FV levels. METHODS: Five different plasma products (6 batches of each) were compared to determine their effectiveness in replacing FV in plasma moderately or severely deficient in FV...

INTRODUCTION: Burn anemia represents a common complication following a burn injury. Burn anemia etiology carries distinct features occurring at each stage of the post-injury and treatment periods resulting from different causes. We aimed to analyze the use of blood components in Finnish burn victims and to identify patient- and injury-related factors influencing their use. METHODS: To study the use of blood products in burn patients, we used data collected from the Optimal Use of Blood registry, developed through co-operation between 10 major hospital districts and the Finnish Red Cross Blood Service...

BACKGROUND: Allergic transfusion reactions (ATRs) present with a broad range of symptoms probably caused by mediators released from mast cells and basophil granulocytes upon activation. Passive immunoglobulin (Ig)E sensitization may yield clinical symptoms and positive allergy tests. Unexpected findings of IgE antibodies in pooled solvent/detergent (S/D)-treated plasma (Octaplas, Octapharma) during routine analysis initiated an investigation of serum proteins. STUDY DESIGN AND METHODS: Consecutive batches of S/D-plasma transfused during September 2014 through March 2015 were investigated for IgE, IgG, IgA IgM, C3, C4, haptoglobin, anti-nuclear antibodies (ANAs), and red blood cell (RBC) antibodies...

BACKGROUND: Major bleeding is rare but among the most serious complications of laparoscopic surgery. Still very little is known on bleeding complications and related blood component use in laparoscopic cholecystectomy (LC). The aim of this study is to compare bleeding complications, transfusion rates and related costs between LC and open cholecystectomy (OC). METHODS: Data concerning LCs and OCs and related blood component use between 2002 and 2007 were collected from existing computerized medical records (Finnish Red Cross Register) of ten Finnish hospital districts...

REVIEW
Andrea Neisser-Svae, Jerard Seghatchian
In recent Coimbra' Conference, on the pre-launch of pathogen reduced-FFP for the local clinical use, the question was raised, by the moderator, on the efficacy of the current methodology used for prion removal processes and its influence on the overall quality and safety of the final product. This brief paper put together by speaker of this session and the moderator, as a consensus of opinions, which was largely discussed during Q&A session, to make it available to a large group of readers of transfusion apheresis science, who might be interested to this topic...

This study assessed the cost-effectiveness of Octaplas™ versus fresh frozen plasma (FFP) in patients receiving plasma transfusions in the United States (US). Acute and long-term complications of plasma transfusions were modelled in a decision tree followed by a Markov model, using a healthcare payer perspective. Over a lifetime time horizon, patients receiving Octaplas™ accumulate slightly more life years (0.00613 [95% uncertainty interval (95%UI): 0.00166-0.01561]) and quality-adjusted life years (QALY) (0...

BACKGROUND: Liver transplantation regularly requires transfusion of red blood cells (RBCs), plasma, and platelets. Compared to fresh frozen plasma (FFP) from single blood donors, solvent/detergent-treated plasma (SD-plasma) pooled from several hundred blood donors has advantages with respect to pathogen reduction, standardized content of plasma proteins, and significantly reduced risk of transfusion related lung injury and allergic/immunologic adverse reactions. However, SD-plasma has been suspected to increase the incidence of hyperfibrinolysis and thromboembolic events...

BACKGROUND: Thromboelastography (TEG) is widely used in hospitals but less commonly in blood banks for evaluation of platelet (PLT) concentrates (PCs). A TEG-PC assay for testing fresh or stored PLTs must reflect the quality of the PLTs. The added value could be measurement of donor-dependent PLT quality. STUDY DESIGN AND METHODS: Whole blood (WB) normal values were generated from 100 donors, using standard tests. Nineteen single-donor PCs were evaluated with a TEG-PC assay, using Octaplas as microparticle-free diluent and kaolin or collagen as activator, stored up to 12 days, and also sampled for additional in vitro tests...

BACKGROUND: Viscoelastic tests such as functional fibrinogen polymerization assays (FFPAs) in thrombelastography (TEG(®)) or thromboelastometry (ROTEM(®)) measure the elasticity of extrinsically activated clotting under conditions of platelet inhibition. There are no reports on whether components of the FFPAs have any effects on fibrin polymerization, aside from the effects of platelet inhibition. METHODS: Using various platelet-free plasma (PFP) preparations, we compared the extrinsically activated EXTEM thromboelastometric assay with 3 FFPAs: FIBTEM, FIBTEM PLUS, and the Functional Fibrinogen Test(®) (FFTEG)...

BACKGROUND: Pooling of plasma of different blood groups before large scale manufacturing of Uniplas(®) results in the formation of low levels of soluble immune complexes (CIC). The aim of this study was to investigate the level and removal of CIC during Uniplas(®) manufacturing. In addition, an in vitro hemolysis assay should be developed and investigate if Uniplas(®) does induce complement-mediated hemolysis of human red blood cells (RBC). MATERIALS AND METHODS: In-process samples from Uniplas(®) (universal plasma) and Octaplas(LG)(®) (blood group specific plasma) routine manufacturing batches were tested on CIC using commercially available ELISA test kits...

BACKGROUND: Fibrinogen replacement is critical in major obstetric haemorrhage (MOH). Purified, pasteurised fibrinogen concentrate appears to have benefit over cryoprecipitate in ease of administration and safety but is unlicensed in pregnancy. In July 2009, the Irish Blood Transfusion Service replaced cryoprecipitate with fibrinogen. OBJECTIVES: To examine the impact of this externally imposed change on blood product use and clinical outcomes in MOH. METHODS: Women with MOH requiring fibrinogen between 1 January 2009 and 30 June 2011 were identified from an MOH database...
