In patients where bleeding is related to coagulation factor deficiency, prothrombin complex concentrates (PCC), or fresh frozen plasma (FFP) administration should be considered to reduce bleeding and transfusions (Boer et al. PMC 91, No. Cryoprecipitate as a reliable source of fibrinogen replacement. Journal of the American College of Cardiology. An official website of the United States government. In vitro and observational studies have demonstrated the importance of fibrinogen replacement for adequate hemostasis, yet randomized controlled trials of fibrinogen treatment compared to placebo have not shown a mortality benefit.19 Cushing and Haas20 examined these clinical trials and determined that fibrinogens inconsistent efficacy may be related to design flaws in the trials themselves, including variable definitions for hypofibrinogenemia, inclusion of patients with insignificant bleeding, and off-protocol interventions. Package insert. In December 2019, a novel human coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in China, where the first case of coronavirus disease 2019 (COVID-19) was described.28 AABB, formerly known as the American Association of Blood Banking, and the US FDA have stated that there are no reported cases of SARS-CoV-2 infection related to blood transfusion.29 Careful screening of blood donors through questionnaires and routine temperature checks, as well as volunteer reporting of COVID-19 symptoms within 48 hours of blood donation, have apparently kept the blood supply safe. Explain the importance of improving care coordination among the interprofessional team to enhance care delivery for patients who can benefit from therapy with prothrombin complex concentrate.

More recently, fibrinogen concentrate has been used off-label in the United States and is the standard in European countries and Canada to treat the acquired hypofibrinogenemia during cardiac surgery. Prothrombin complex concentrate in cardiac surgery for the treatment of coagulopathic bleeding. Antibodies associated with causingtransfusion-related acute lung injury (TRALI,defined as newacute lung injury that developed during or within 6 hours of transfusion of one or more units, not attributable to another ALI risk factor) - a significant cause of death after transfusion) are removed from PCC during the manufacturing process; therefore, PCC is associated with minimal risk compared to FFP. 0000049748 00000 n Safety of fibrinogen concentrate: analysis of more than 27 years of pharmacovigilance data.

FIBRES - Effect of fibrinogen concentrate vs cryoprecipitate on blood component transfusion after cardiac surgery; 12 FP = frozen plasma; PCC = prothrombin complex concentrate. FFP requires procurement from the blood bank and thawing before administration, factors that lead to delays in administration and anticoagulation reversal. During massive hemorrhage, thawing time may be detrimental, leading to an additional hemodilution or consumptive coagulopathy, as the minimal fibrinogen is given in other allogeneic blood products. endobj In this Pro-Con commentary article, we discuss the advantages and disadvantages of using fibrinogen concentrate and cryoprecipitate to treat acquired hypofibrinogenemia in cardiac surgical patients. Prothrombin complex concentrate ( PCC ), also known as factor IX complex, is a medication made up of blood clotting factors II, IX, and X. The PCCs are standardized according to their factor IX content. 2019; 59:15601567. 2011; 25:267292. The two groups were then compared for: correction of INR, time to correction of INR, thromboembolic complications, mortality, and cost of therapy. The risk of pathogen transmission is one of the primary reasons that cryoprecipitate was removed from European markets. Roy A, Stanford S, Nunn S, et al.

Chandler WL. Conflicts of Interest: N. B. Hensley has served on the scientific advisory board for Octapharma USA (Paramus, NJ) and received royalties from Wolters Kluwer for uptodate.com contributions. A major criticism of these studies is that patients received fibrinogen concentrate without demonstrating low fibrinogen concentration, and in 1 trial, without clinically significant bleeding, because fibrinogen concentrate was given before surgery. It was developed as a treatment for haemophilia but this use has now been replaced by Factor VIII concentrate. Patients had to be normothermic, have an activated clotting time within 25% of their baseline value, and have a pH value of >7.3.41 The study found that there was a median of 5.0 (interquartile range [IQR], 2.011.0) units of allogeneic blood products administered in the fibrinogen concentrate group within 24 hours versus only 3.0 (IQR, 0.07.0) units in the placebo group (P = .026). PCC is leukocyte-free and less likely to cause infusion reactions. It catalyzes the conversion of fibrinogen to fibrin and also activates platelets through protease-activated receptors (PARs) 1 and 4 on platelet surfaces. 5. Noninferiority was also met for the secondary outcomes, including 24-hour and cumulative 7-day blood component transfusion and cumulative transfusion measured from product administration to 24 hours after CPB. 2019; 322:111. Clipboard, Search History, and several other advanced features are temporarily unavailable. Pharmacists can be an excellent resource in this setting, guiding clinicians concerning dosing and indications for administration and answering team members' questions about the medication. The indications are listed below. One donor positive platelet unit was pathogen reduced and transfused 3 days after donation to a patient who remained asymptomatic, and a red blood cell (RBC) unit was given to a SARS-CoV-2positive patient. Fibrinogen, which is a plasma glycoprotein that is made in the liver (half-life of ~100 hours), is a critical substrate for thrombin. J Thromb Haemost. 10. The FIBRES study reported a 2.6% higher thromboembolism rate in patients who received cryoprecipitate at 9.6% compared to 7.0% in patients who received fibrinogen concentrate (Table 1); however, this difference was not statistically different.24, Another randomized controlled trial, which included patients with pseudomyxoma peritonei and cytoreductive surgery, found a higher incidence of thromboembolic events in the cryoprecipitate group at 30.4% (7 of 23) compared to 0% (0 of 22) in the fibrinogen concentrate group.44 In a recent systematic review of randomized controlled trials examining fibrinogen concentrate, the authors concluded that the overall risk of thromboembolism is probably extremely low, and no studies reported a significantly increased risk of thromboembolism in patients receiving fibrinogen concentrate.20, Despite the findings of the FIBRES study, cryoprecipitate may be superior in some cardiac surgical patients.24 In the FIBRES study, the median CPB duration was 130140 minutes, but the CPB duration is often longer in complex aortic surgery with deep hypothermic circulatory arrest or in the other combined cardiac surgery procedures.

In cases with long CPB duration, particularly in complex congenital heart surgery, acquired von Willebrand syndrome (VWS) is common, and cryoprecipitate may be a superior option for replacing both fibrinogen and large VWF multimers.51 Finally, patients on extracorporeal membrane oxygenation (ECMO) and patients with ventricular assist devices (VADs) are well known to have acquired VWS and may benefit from the treatment with cryoprecipitate compared to fibrinogen concentrate.5254. The treatment with fibrinogen concentrate will not replace VWF multimers, and poor platelet adhesion may persist despite normalization of fibrinogen.
