Liver Transplantation as a Novel Strategy for Resolution of Congenital Afibrinogenemia in a Pediatric Patient.

Liver Transplantation as a Novel Strategy for Resolution of Congenital Afibrinogenemia in a Pediatric Patient. J Thromb Haemost. 2020 Sep 05;: Authors: Corrales-Medina FF, Miloh T, O'Farrell C, Andrews DM, Tekin A, De Angulo G Abstract Fibrinogen replacement therapy is a treatment mainstay for patients with afibrinogenemia and significant bleeding. A male infant with congenital afibrinogenemia and several spontaneous hemarthroses commenced cryoprecipitate prophylaxis but developed severe urticarial reactions. He transitioned to a human fibrinogen concentrate (HFC) (RiaSTAP®, CSL Behring; 70 mg/kg biweekly) but continued experiencing hemarthroses (estimated annualized bleeding rate [ABR]: 5-6) and severe anaphylactic reactions, despite pre- and post-infusion medications. Following switching to a new HFC (Fibryga®, Octapharma; 50 mg/kg biweekly), ABR was 0-1 with no further infusion reactions. Aged 9 years, due to limited quality-of-life, development of obesity and fatty liver disease, he underwent orthotopic liver transplant (OLT) under HFC coverage. Pharmacokinetic analysis guided presurgical fibrinogen levels >150 mg/dL. No intraoperative HFC infusions were required. Coagulation profile and fibrinogen levels remained within normal limits during and post-transplant. To our knowledge, this is the first pediatric report of afibrinogenemia successfully treated with OLT. PMID: 32890454 [PubMed - as supplied by publisher]
