Summary

Acquired bleeding disorders are the most common causes of bleeding seen in the practice of hematology. These entities can be due to interference with the platelet plug formation, interference with blood coagulation proteins, and interference with both. The physician needs to be cognizant of these entities to recognize hemostatic problems arising during the course of an illness or as result of therapies. Quantitative or qualitative defects in platelet plug formation can arise from immune thrombocytopenia, drug-induced thrombocytopenia, anti-platelet medications, or interfering monoclonal immunoglobulins. Acquired defects in blood coagulation proteins can arise from anticoagulation and fibrinolytic therapies, vitamin K deficiency, massive transfusion, and acquired inhibitors. Both disseminated intravascular coagulation and liver disease contribute to acquired bleeding disorders due to defects in both platelets and blood coagulation proteins.
