Immune Thrombocytopenia Associated with Hepatitis B Virus and Autoimmune Hepatitis and Recovery of Platelet Count following Liver Transplantation.

Immune thrombocytopenia is a consumptive coagulopathy that can be either idiopathic or associated with infectious or autoimmune etiologies. Here, we present a case of immune thrombocytopenia in the setting of acute liver failure due to coexisting diagnoses of hepatitis B virus and autoimmune hepatitis. Our patient underwent orthotopic liver transplantation and recovered hemostatic platelet counts after treatment with romiplostim, a thrombopoietin receptor agonist, 51 days after transplantation. To our knowledge, this is the first case report of immune thrombocytopenia secondary to both hepatitis B virus and autoimmune hepatitis in a patient with acute liver failure.
