Liver disease associated coagulopathy

Liver disease associated coagulopathy
Updated: 07/25/2023
© Jun Wang, MD, PhD

General features
  • Multiple factor deficiency due to impaired production in liver
  • Vitamin K deficiency may exacerbate deficiency of VK associated factors (II, VII, IX, X)
  • Two factors not affected by abnormal liver function
Factor VIII produced by endothelial cells
Factor XIII, produced in bone marrow
Clinical presentations
  • Bleeding
  • Thrombosis: Decreased plasminogen, protein C and protein S
  •  Presentations associated with liver failure, such as esophageal varices
Key pathogenesis
  • Impaired production of coagulation factors
Key Laboratory findings
  • Prolongations of aPTT, PT, INR
  • Mild thrombocytopenia
  • Elevated D-dimer
  • Normal level of factor VIII
Differential diagnosis
  • TTP: Clinical setting, normal PT and PTT, low ADAMTS13
  • HIT: History of heparin usage, normal PT, aPTT and fibrinogen, antibodies against PF4
  • DIC: Usually reduced levels of factor VIII

Lymphoid neoplasms

Lymphocytic neoplasms Updated: 05/17/2020 © Jun Wang, MD, PhD Terminology Lymphoma : Proliferations forming discrete tissue masses Leukemia : Widespread involvement of the bone marrow and usually the peripheral blood Any "lymphoma" can present with or evolve to a leukemic picture, and any "leukemia" can occasionally present with a mass lesion Other hematology terms Important risk factors Immunodeficiency (primary or secondary) Autoimmune disorders Viruses (HIV, KSHV/HHV8, HTLV-1) H. pylori infection Radiation Chemotherapy Diagnostic approaches Complete history, especially those with possible epidemic characters, such as Burkitt lymphoma CBC, Bone marrow Morphology/immunohistochemistry Immunofluorescence flow cytometry Cytogenetic studies Molecular studies Commonly used markers All lymphomas: CD45 B-cell neoplasms: CD5, CD10, CD19, CD20, CD79a, CD23, bcl2, bcl6, cyclin D1, light chai
