The Relentless Recurrence of Diffuse Alveolar Hemorrhage in Catastrophic Antiphospholipid Syndrome and Lupus: A Therapeutic Challenge.

ABSTRACT

Diffuse alveolar hemorrhage (DAH), a rare complication of coexisting antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE), poses significant diagnostic and therapeutic challenges, especially with recurrent episodes. We present a 27-year-old male with catastrophic APS and SLE who experienced acute respiratory failure and hemoptysis due to DAH. Despite aggressive therapy with immunosuppressants, plasma exchange, and anticoagulation, he had recurrent DAH episodes requiring repeated admissions. Early recognition, multidisciplinary management, and utilization of effective targeted therapies, such as intravenous immunoglobulin, in refractory cases are crucial for improving outcomes in this challenging complication.
