Abstract
BACKGROUND Fibrinolytic activity contributes to bleeding after cardiopulmonary bypass (CPB). OBJECTIVE Our objectives were, in a group of infants undergoing cardiac surgery with CPB: to document the extent of peri-operative fibrinolysis using rotational thromboelastometry (ROTEM) and standard biomarkers; to compare the agreement between these fibrinolytic measures; to assess whether fibrinolytic activity is associated with early postoperative mediastinal bleeding and assess whether supplementation with fibrinogen concentrate affected fibrinolysis. DESIGN Prospective cohort, mechanistic substudy, nested within the FIBrinogen CONcentrate (FIBCON) randomised controlled trial. SETTING Single centre, tertiary paediatric cardiac surgery and paediatric intensive care units. PATIENTS Ninety infants (median age 6.3 months) undergoing cardiac surgery, who all received routine intra-operative tranexamic acid. The infants were randomised to receive either an individualised dose of fibrinogen concentrate ( n = 60) or placebo ( n = 30) during CPB. MAIN OUTCOME MEASURES We measured the ROTEM variable maximum clot lysis (ML), and fibrinolytic biomarkers including plasmin-antiplasmin (PAP) and tissue plasminogen activator antigen (tPA-Ag). Blood was sampled pre-CPB, on-CPB and post-CPB, and 4 h after PICU admission. RESULTS tPA-Ag, PAP and ROTEM ML increased significantly after CPB despite the use of tranexamic acid. The two fibrinolytic biomarkers t-PA and PAP, correlated ( P = 0.001) but neither correlated with ROTEM ML. Early postoperative blood loss was inversely associated with PAP levels. Each 100 μg l -1 rise in PAP was associated with a 7.9% reduction in mean blood loss. Fibrinogen concentrate supplementation as expected did not affect tPA-Ag but was temporally associated with an increase in PAP levels and a decrease in ROTEM fibrinolytic activity. CONCLUSION Fibrinolysis is activated after paediatric cardiac CPB surgery as indicated by increased tPA-Ag and ROTEM ML. The substantial increase in tPA-Ag post-PICU admission is probably accompanied by a similar rise of plasminogen activator inhibitor 1 (PAI-1) as part of the acute phase response to surgery, thereby limiting clinical fibrinolysis. Supplementation of fibrinogen concentrate was associated with increased PAP activity and less clinical bleeding, consistent with the known role for fibrinogen in being a substrate for plasmin.

Abstract
BACKGROUND Intraoperative hemorrhage in cardiac surgery increases risk of morbidity and mortality. Low pre-operative and perioperative levels of fibrinogen, a key clotting factor, are associated with severity of hemorrhage and increased transfusion of blood components. The ability to supplement fibrinogen during hemorrhagic resuscitation is delayed 45-60 min because cryoprecipitated antihemophilic factor (cryo AHF) is stored frozen, due to a short post-thaw shelf life. Pathogen Reduced Cryoprecipitated Fibrinogen Complex (INTERCEPT Fibrinogen Complex, IFC) can be kept thawed, at room temperature, for up to 5 days, making it possible to be immediately available for hemorrhaging patients. This trial will investigate if earlier correction of acquired hypofibrinogenemia with IFC in hemorrhaging cardiac surgery patients reduces the total number of perioperatively transfused allogeneic blood products (red blood cells, plasma, and platelets) as compared to cryo AHF. METHODS This is a single center, prospective, cluster randomized trial with an adaptive design. Acquired hypofibrinogenemia will be assessed by rotational thromboelastometry (ROTEM) and the threshold for cryo AHF/IFC transfusion defined as FIBTEM A10 ≤ 10 mm in bleeding patients. IFC/cryo AHF will be randomized by 1-month blocks. Cardiac surgery patients will be enrolled in the study if they have an eligible procedure and at least one dose of a cryo AHF/IFC product (approximately 2 g fibrinogen) is transfused. Data from the electronic health record, including the blood bank and lab information systems, will be prospectively collected from the health system's data warehouse. DISCUSSION This trial aims to provide evidence of the clinical efficacy of utilizing readily available thawed IFC during acute bleeding in the cardiac surgery setting compared to traditional cryo AHF. TRIAL REGISTRATION ClinicalTrials.gov NCT05711524. Feb 3, 2023.

Abstract
RATIONALE Abnormal bleeding due to low fibrinogen (Fib) and coagulation factor XIII (FXIII) levels after lumbar vertebral surgery is exceedingly rare. Excessive bleeding is also associated with secondary hyperfibrinolysis. This report presents a case of abnormal incision bleeding caused by coagulation factor XIII deficiency (FXIIID) and secondary hyperfibrinolysis in a state of low fibrinogen after lumbar vertebral surgery. PATIENT CONCERNS A middle-aged woman experienced prolonged incision and excessive bleeding after lumbar vertebral surgery. DIAGNOSIS Combined with coagulation factors, coagulation function tests, and thromboelastography, the patient clinical presentation supported the diagnosis of FXIIID and secondary hyperfibrinolysis in a hypofibrinogenemic state. INTERVENTIONS Cryoprecipitat, Fresh Frozen Plasma, Fibrinogen Concentrate, Leukocyte-depleted Red Blood Cells, Hemostatic (Carbazochrome Sodium Sulfonate; Hemocoagulase Bothrops Atrox for Injection; Tranexamic Acid). OUTCOMES After approximately a month of replacement therapy and symptom treatment, the patient coagulation function significantly improved, and the incision healed without any hemorrhage during follow-up. LESSONS Abnormal postoperative bleeding may indicate coagulation and fibrinolysis disorders that require a full set of coagulation tests, particularly coagulation factors. Given the current lack of a comprehensive approach to detect coagulation and fibrinolysis functions, a more comprehensive understanding of hematology is imperative. The current treatment for FXIIID involves replacement therapy, which requires supplementation with both Fib and FXIII to achieve effective hemostasis.

Abstract
BACKGROUND Hyperfibrinolysis is a possible complication during liver transplantation, particularly immediately after reperfusion. METHODS We performed a retrospective study to examine the incidence, treatment, and resolution of postreperfusion hyperfibrinolysis in patients undergoing liver transplantation at Duke University Hospital from 2015 to 2020. RESULTS Out of 535 patients undergoing liver transplantation, 21 or 3.9%, 95% CI (2.5-5.9), had hyperfibrinolysis after reperfusion. Hyperfibrinolysis occurred in 16 of 511 (3.1%) patients receiving livers from DBD donors, 5 of 18 (27.8%) patients receiving livers from donation after circulatory death (DCD) donors, and 0 of 6 (0.0%) patients receiving livers from living donors. Fibrinolysis was treated with cryoprecipitate (12/21), a combination of cryoprecipitate and tranexamic acid (3/21), or neither (6/21) and resolved within several hours in all cases. CONCLUSIONS Anesthesiologists should be aware of the possibility of postreperfusion hyperfibrinolysis in liver transplantation, particularly with DCD donors, and may consider treatment with cryoprecipitate or tranexamic acid. Further work is needed to identify any potential differences, such as faster resolution of fibrinolysis, between different treatment modalities.

Abstract
Cryoprecipitate is a transfusion blood product derived from fresh-frozen plasma (FFP), comprised mainly of the insoluble precipitate that gravitates to the bottom of the container when plasma is thawed and refrozen. It is highly enriched in coagulation factors I (fibrinogen), VIII, and XIII; von Willebrand factor (vWF); and fibronectin. In this article, we have reviewed currently available information on the preparation, properties, and clinical importance of cryoprecipitate in treating critically ill neonates. We have searched extensively in the databases PubMed, Embase, and Scopus after short-listing keywords to describe the current relevance of cryoprecipitate.

Abstract
Background Fibrinogen concentrates and cryoprecipitate are currently used for fibrinogen supplementation in bleeding patients with dysfibrinogenemia. Both products provide an abundant source of fibrinogen but take greater than 10 min to prepare for administration. Fibrinogen concentrates lack coagulation factors (i.e., factor VIII [FVIII], factor XIII [FXIII], von Willebrand factor [VWF]) important for robust hemostatic function. Cryoprecipitate products contain these factors but have short shelf lives (<6 h). Pathogen reduction (PR) of cryoprecipitate would provide a shelf‐stable immediately available adjunct containing factors important for rescuing hemostatic dysfunction. Study Design and Methods Hemostatic adjunct study products were psoralen‐treated PR‐cryoprecipitated fibrinogen complex (PR‐Cryo FC), cryoprecipitate (Cryo), and fibrinogen concentrates (FibCon). PR‐Cryo FC and Cryo were stored for 10 days at 20–24°C. Adjuncts were added to coagulopathies (dilutional, 3:7 whole blood [WB]:normal saline; or lytic, WB + 75 ng/ml tissue plasminogen activator), and hemostatic function was assessed by rotational thromboelastometry and thrombin generation. Results PR of cryoprecipitate did not reduce levels of FVIII, FXIII, or VWF. PR‐Cryo FC rescued dilutional coagulopathy similarly to Cryo, while generating significantly more thrombin than FibCon, which also rescued dilutional coagulopathy. Storage out to 10 days at 20–24°C did not diminish the hemostatic function of PR‐Cryo FC. Discussion PR‐Cryo FC provides similar and/or improved hemostatic rescue compared to FibCon in dilutional coagulopathies, and this rescue ability is stable over 10 days of storage. In hemorrhaging patients, where every minute delay is associated with a 5% increase in mortality, the immediate availability of PR‐Cryo FC has the potential to improve outcomes.

Suggestions for global coagulation assays for the assessment of COVID-19 associated hypercoagulability. Thromb Res 2021; 201:84-89.

Abstract
Introduction Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection is associated with a clear prothrombotic phenotype. Although the exact pathophysiological mechanisms are not yet fully understood, thrombosis is clearly a highly important in the prognosis and outcome of COVID-19. As such, there is a need for diagnostic analysis and quantification of the coagulation potential in these patients, both at diagnosis and follow-up. Global coagulation assays like thrombin generation (TG) and rotational thromboelastometry (ROTEM) might be suitable in estimating COVID-19 associated coagulopathy and thrombosis risk. Therefore, we aimed at validating both assays for samples with high levels of fibrinogen and in the presence of anticoagulant heparins, such as commonly observed for COVID-19 ICU patients. Materials and methods Calibrated Automated Thrombography (CAT) was optimized to assess plasma thrombin generation in the presence of heparins. The final conditions with either 10 μg/mL Ellagic acid (EA) or PPP Reagent HIGH (high tissue factor; HPPH) were validated according to the EP5 protocol for within-run and between-run variability. Overall variability was well below 10%. To estimate the influences of heparins and high fibrinogen levels, CAT was performed on spiked plasma aliquots from 13 healthy volunteers. Comparable to the CAT method, tPA-ROTEM was used to validate the effect of high fibrinogen and heparins on clotting time, clot firmness and clot lysis parameters. Results Our adjusted COVID-19 assay showed a heparin dose dependent decrease in peak height and endogenous thrombin potential (ETP) for both EA and HPPH triggered variants. High fibrinogen did not alter the inhibitory effect of either LMWH or UFH, nor did it influence the peak height or ETP in any of the conditions. The tPA-ROTEM showed a significant prolongation in clotting time with the additions of heparin, which normalized with the addition of high fibrinogen. MCF was markedly increased in all hyperfibrinogenemic conditions. A trend towards increased lysis time and, thus, decreased fibrinolysis was observed. Conclusion Thrombin generation and tPA-ROTEM protocols for measurements in the COVID-19 populations were adjusted and validated. The adjusted thrombin generation assay shows good sensitivity for measurements in heparin spiked plasma. High levels of fibrinogen did not alter the assay or the effectiveness of heparins as measured in this assay. t-PA ROTEM was effective in measurement of both high fibrinogen and heparins spiked samples and was sensitive to the expected relevant coagulant changes by these conditions. No clear fibrinolytic effect was observed in different conditions.

Abstract
Fibrinogen is a key coagulation protein, playing a critical role in hemostasis. It is the first factor to decrease to critical levels during bleeding. Hypofibrinogenemia is an important risk factor for bleeding in clinical settings, including pediatric surgery. Yet, the optimal measurement of fibrinogen levels is subject to debate, as is the critical threshold for intervention. Fibrinogen replacement may be provided by cryoprecipitate and fibrinogen concentrate. Whilst both products contain fibrinogen, they are not equivalent, each has its own advantages and disadvantages, especially for pediatric use. Unfortunately, medical literature to support fibrinogen replacement in children is limited. In this article we review the current diagnostic tools to measure fibrinogen, with respect to their use in the pediatric critical care setting. Secondly, we evaluate the different fibrinogen replacement therapies, focusing on cryoprecipitate and fibrinogen concentrate and examine their individual product characteristics, associated risks and benefits, different dosing strategies and specific pitfalls for use in children. We summarize by highlighting current knowledge gaps and areas for future research.

Abstract
The importance of the targeted treatment of acquired hypofibrinogenemia during hemorrhage with a concentrated fibrinogen product (either cryoprecipitate or fibrinogen concentrate) cannot be underestimated. Fibrinogen concentrate is a pathogen inactivated, pooled product that offers a highly purified single factor concentrate. Cryoprecipitate is a pooled product that comes with a spectrum of other coagulation factors which may further enhance (additional procoagulant effect) or even disturb (prothrombotic risk) hemostasis. The pros and cons of each product are discussed.

Abstract
Acute coagulopathy is common after traumatic brain injury (TBI), particularly in severe cases of acute subdural hemorrhage (ASDH). Although acute coagulopathy is associated with poor outcomes, the optimal treatment strategy remains unknown. Here, we report the initial results of an empirical cryoprecipitate transfusion strategy that we developed as an early intervention for acute coagulopathy after TBI. We performed chart reviews of adult patients (aged ≥18 years) who received early cryoprecipitate transfusion after admission to our institution with a diagnosis of severe TBI (Glasgow Coma Scale ≤8) and ASDH from March 2013 to December 2016. We compared the outcomes of these patients with those who were treated before the implementation of the cryoprecipitate transfusion strategy (January 2011-February 2013). During the study period, 33 patients received early cryoprecipitate transfusion and no acute transfusion-related adverse event was reported. The rate of coagulopathy development within 24 h after admission was lower in these patients (23%) than in the controls (49%), but the difference was not significant (P = 0.062). The in-hospital mortality rate was 36% in patients receiving early cryoprecipitate transfusion and 52% in controls. After adjusting for confounding factors, the in-hospital mortality rate was significantly lower in the intervention period [adjusted odds ratio: 0.25, 95% confidence interval (CI): 0.08-0.78, P = 0.017]. In summary, we analyzed initial results of a cryoprecipitate transfusion strategy in patients with severe isolated TBI and ASDH. No acute transfusion-related adverse event was observed, and early transfusion of the in-house-produced cryoprecipitate may have reduced rates of coagulopathy development and in-hospital mortality.

Effects of in-house cryoprecipitate on transfusion usage and mortality in patients with multiple trauma with severe traumatic brain injury: a retrospective cohort study. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2019; 18:6-12. [PMID: 30747700 DOI: 10.2450/2019.0198-18] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 10/06/2018] [Accepted: 12/14/2018] [Indexed: 12/22/2022]
Abstract
BACKGROUND Hypofibrinogenaemia is a common complication of multiple trauma with severe traumatic brain injury (Abbreviated Injury Scale score of the head ≥4; body ≥3). In Japan, neither fibrinogen concentrate nor cryoprecipitate is permitted to treat acquired hypofibrinogenaemia with the purpose of rapidly restoring a haemostatic level of fibrinogen. The aim of this study was to investigate transfusion usage and mortality in patients with multiple trauma and severe traumatic brain injury who were given a cryoprecipitate prepared in-house, comparing those administered the product early or later. MATERIAL AND METHODS We prepared and produced cryoprecipitate from fresh-frozen plasma beginning in March 2013. We performed a retrospective cohort study of patients admitted to our single tertiary medical centre with severe multiple trauma with traumatic brain injury from March 2013 to June 2018, sorting them into those given the cryoprecipitate infusion within 90 minutes of admission (Early group) and those given it more than 90 minutes after admission (Late group). Clinical outcomes were compared between the two groups using chi-square or Fisher's exact tests and the Wilcoxon test as appropriate. RESULTS There were 26 and 16 patients in the Early and Late groups, respectively. The 24-hour mortality tended to be lower in the Early group than in the Late group (8 vs 13%, respectively). The patients were more severely anaemic and thrombocytopenic after haemostatic therapy in the Late group than in the Early group. Transfusion usage in the Early group was lower than that in the Late group (red blood cells: 7±1 units vs 17±3 units, p<0.05; fresh-frozen plasma: 9±1 units vs 16±3 units, p<0.05; platelet concentrate: 3±1 units vs 15±4 units, p<0.05, respectively). DISCUSSION Early administration of an in-house cryoprecipitate may reduce transfusion usage in patients with multiple trauma with severe traumatic brain injury.

Abstract
Decompressive craniectomy (DC) is a therapeutic alternative for reducing intracranial pressure after a middle cerebral artery stroke. If thrombolytic therapy is administered, craniectomy is usually postponed for at least 24 hours due to a risk of severe bleeding. We describe a case in which DC was performed on a 38-year-old man who received thrombolytic therapy for an ischemic stroke involving the middle cerebral artery. His neurological and hemodynamic status worsened during its administration, and DC was performed 6 hours after thrombolysis was performed. Fibrinolytic coagulopathy was successfully managed by monitoring fibrinogen levels and with the administration of cryoprecipitate and tranexamic acid.
