Uncovering the Link Acquired Hemophilia A in a Patient with Prostate Adenocarcinoma

Introduction

Case Overview Unusual Bleeding in a Cancer Patient

  • A 71-year-old male with prostate cancer presented with spontaneous soft-tissue bleeding and prolonged activated partial thromboplastin time (aPTT).
  • Initial coagulation tests showed isolated aPTT prolongation with normal prothrombin time and platelet count.
  • Further diagnostics confirmed high factor VIII inhibitor levels, leading to the diagnosis of Acquired Hemophilia A.

Management and Treatment Outcomes

  • Immunosuppressive therapy, including corticosteroids and rituximab, was initiated.
  • Hemostatic support with bypassing agents (e.g., recombinant activated factor VII) was essential to control bleeding.
  • Patient outcomes improved with suppression of the inhibitor and successful management of the underlying malignancy.

Clinical Significance and Broader Implications

Acquired Hemophilia A is often underdiagnosed due to its nonspecific bleeding symptoms, especially in the elderly or those with malignancies. It requires a high index of suspicion for timely diagnosis.

The National Hemophilia Foundation underscores the critical need for swift diagnosis and a multidisciplinary approach in managing such bleeding disorders to prevent severe complications and mortality.

Moreover, this case contributes valuable insights into the intersection of autoimmunity and oncology, highlighting how solid tumors like prostate adenocarcinoma can serve as a trigger for autoimmune coagulopathies.

Key Takeaways

  • AHA is a rare autoimmune bleeding disorder that can arise secondary to malignancies.
  • Early identification and tailored immunosuppressive therapy are crucial for favorable outcomes.
  • Routine coagulation screening can uncover atypical disorders in cancer patients.
  • Multidisciplinary management is key to both hemostasis and cancer care.
