Thromboelastometry identifies coagulopathy associated with liver failure and disseminated intravascular coagulation caused by yellow fever, guiding specific hemostatic therapy: a case report

Abstract

This case report a severe case of yellow fever complicated by liver failure and disseminated intravascular coagulation. Thromboelastometry was capable of identifying clotting disorders and guiding hemostatic therapy. We report the case of a 23-year-old male admitted to the Intensive Care Unit with sudden onset of fever, generalized muscle pain associated with liver failure, and disseminated intravascular coagulation. The results of conventional laboratory tests showed thrombocytopenia, whereas thromboelastometry suggested coagulopathy with slight hypofibrinogenemia, clotting factor consumption, and, consequently, an increased risk of bleeding. Unlike conventional laboratory tests, thromboelastometry identified the specific coagulation disorder and thereby guided hemostatic therapy. Both fibrinogen concentrates and vitamin K were administered, and no blood component transfusion was required, even in the presence of thrombocytopenia. Administration of hemostatic drugs, including fibrinogen concentrate and vitamin K, improved thromboelastometric parameters, correcting the complex coagulation disorder. Blood component transfusion was not performed, and there was no bleeding.

Comparación clínica y laboratorial de la fiebre amarilla severa versus dengue grave en Perú

“…Esto contrasta con el estudio realizado en Puerto Maldonado, Perú, donde el recuento de plaquetas de los pacientes con dengue grave se encontraba dentro de los rangos normales, excepto en el grupo de 10 a 19 años que se encontraban por debajo de 150.000/mm 3 (Rojas et al, 2015). Por otro lado, en un reporte de un paciente con fiebre amarilla que desarrolló coagulación intravascular diseminada presentó recuentos bajos de plaquetas desde el inicio de la enfermedad (Crochemore et al, 2020).…”
