Abstract

Activated partial thromboplastin time may be prolonged as the result of either of two different autoimmune complications of chronic lymphocytic leukemia: the development of antiphospholipid antibodies, such as lupus anticoagulant or anticardiolipin antibodies, or anti-factor VIII inhibitors, such as acquired hemophilia A. In the rare simultaneous occurrence of both inhibitors, differential diagnosis of a prolonged activated partial thromboplastin time poses a number of problems during laboratory work-up, due to mutual interference of the commonly performed tests. Only careful clinical follow-up can disclose the significance of the laboratory findings. We report the case of concurrent antiphospholipid antibodies (lupus anticoagulant positivity, anticardiolipin antibodies; IgM 3880 MPL/mL and IgG 265 GPL/mL) and anti-factor VIII antibodies (46.8 Bethesda Units) in a patient with chronic B-cell lymphocytic leukemia who had prolonged activated partial thromboplastin time (78.8 s). The relationship between lymphoproliferative and antiphospholipid syndrome, laboratory workup in the case of the association of antiphospholipid and anti-factor VIII antibodies, and related problems that occur during clinical management of the patient are also discussed.
