Jamie Bering, MD

Lewis J. Wesselius, MD

 

Department of Pulmonary Medicine

Mayo Clinic Arizona

Scottsdale, AZ

 

History of Present Illness

The patient is a 53-year-old woman transferred for acute respiratory failure and hemoptysis. She has a prior history of antiphospholipid syndrome and recurrent diffuse alveolar hemorrhage (DAH). She was admitted to another hospital about 2 weeks prior to transfer with hypoxic respiratory failure which ultimately required intubation. Bronchoscopy revealed a bloody aspirate raising concerns for recurrent DAH. She was started on high-dose solumedrol and extubated after 4 days. One week later, her respiratory status decompensated and her chest x-ray showed worsening diffuse bilateral opacities concerning for recurrent DAH. She was transferred to the Mayo Clinic Arizona for further evaluation. Upon arrival, she required 50% FiO2 by face mask to maintain adequate oxygenation and was started on broad-spectrum antibiotics. Her corticosteroids were tapered to 20 mg prednisone daily.

Past Medical History, Social History and Family History

She has a history of a mitral valve replacement with a St. Jude’s mechanical mitral valve and was on chronic anticoagulation with warfarin. In addition, there was a history of moderate aortic stenosis with moderate aortic insufficiency.

She had a history of diffuse alveolar hemorrhage, antiphospholipid antibody syndrome and possible systemic lupus erythematosus.
