Expecting the unexpected: Acquired haemophilia A in a patient with homozygous factor V deficiency

Acquired haemophilia A (AHA) is a rare, potentially life‐threatening bleeding disorder characterized by the development of autoanti‐ bodies to factor VIII [FVIII],1 and in approximately 40% of cases,2 an underlying condition, such as autoimmune disease or pregnancy, can be identified. Postpartum AHA accounts for 2%‐21% of cases,2,3 is more common in primigravidae and typically presents with major bleeding within the first 3 months after delivery.5 Postpartum hae‐ morrhage (PPH) is not uncommon, and bleeding during this period may be attributed to obstetric causes, such as uterine atony.6 This may delay the diagnosis of AHA and contributes to the morbidity and mortality of this condition. Furthermore, the presence of a con‐ genital bleeding disorder can overshadow AHA diagnosis since labo‐ ratory measurements may not provide a clue. We report the case of a female with homozygous factor V (FV) deficiency that developed postpartum AHA.
