Melissa is a 35-year-old mother of three who works in marketing. She is being seen in consultation by the Internal Medicine service while admitted to Thoracic Surgery for an empyema. Three months ago, she began to have cough with intermittent fevers and chills. She has been treated as an outpatient by her family doctor with Amoxicillin, Azithromycin and Levofloxacin over this time. Her symptoms would initially improve but would return within days of completing her antibiotic course. Her condition continued to worsen until this admission. On review of her past medical history, she has chronic facial pain and pressure with frequent purulent discharge, and typically has 2-3 sinus infections per year requiring antibiotics. She also has a long-standing history of autoimmune disease. She was diagnosed with immune thrombocytopenia purpura (ITP) in her early 20s, and one episode of acute autoimmune hemolytic anemia. Each of these presentations was treated with steroids. She was also diagnosed with hypothyroidism at 16, attributed to autoimmune thyroiditis. Over the past several years, she has experienced chronic diarrhea and abdominal pain and underwent a colonoscopy which demonstrated inflammatory changes.
