A Multifactorial Case of Acquired Hemophilia A
Jason P Willis, Timothy Kanne, Alex Cole, Grant Nelson

TL;DR
A 73-year-old woman with multiple health issues developed a rare autoimmune bleeding disorder, which led to severe complications and ultimately death despite treatment.
Contribution
This case study presents a complex clinical scenario of acquired hemophilia A with comorbidities, emphasizing management challenges and outcomes.
Findings
The patient's AIHA was complicated by heart disease, diabetes, hypertension, and a positive lupus anticoagulant test.
Despite treatment with corticosteroids, cyclophosphamide, rituximab, and factor VIIA, she had recurring bleeding and complications.
The case underscores the need for early diagnosis, multidisciplinary care, and individualized treatment in AIHA.
Abstract
Acquired hemophilia A (AIHA) is a rare autoimmune bleeding disorder in which the body develops autoantibodies against factor VIII, leading to spontaneous bleeding. It has an incidence of about one person per million each year. AIHA carries high risks; these symptoms are only exacerbated with other comorbidities, as explored in this patient, a 73-year-old female patient with a history of heart disease, diabetes, hypertension, and a positive lupus anticoagulant (LA) test. She presented with a rapidly growing neck hematoma that compromised her airway, requiring immediate intubation and admittance to the ICU. Laboratory tests showed a severely prolonged activated partial thromboplastin time (aPTT) and critically low factor VIII levels, confirming the diagnosis of AIHA. Despite early treatment with corticosteroids, cyclophosphamide, rituximab, and recombinant factor VIIA, she experienced…
