Acquired Haemophilia A in Association with Influenza A and Urinary Tract Infection.

Abstract

The lack of awareness of and experience with acquired haemophilia (AHA) suggests that diagnosis is frequently delayed, resulting in suboptimal treatment.AHA should be suspected in recent-onset abnormal bleeding in patients not receiving anticoagulant treatment, and in the presence of isolated prolonged activated partial thromboplastin time (aPTT).Treatment is based on eradication of the inhibitor, control of the bleeding and identification of underlying conditions.
