Legionnaires' disease - reliability of urine antigen testing
A 58 year old male patient presents to the emergency room with shortness of breath for the last few days. He also complains of chills, a cough, myalgia, and diarrhea. His notable findings include WBC = 14 k/uL, Scr = 1.2 mg/dL, BUN = 27 mg/dL, BP = 132/76 mm Hg, RR = 30 breaths/minute, Tmax = 38.5⁰C, and O2sat = 92% on room air. His chest x-ray reveals a patchy infiltrate suggestive of pneumonia. Upon further questioning, the patient tells you he lives across the street from an apartment building where several people recently were diagnosed with Legionnaires' disease. He has no recent exposure to any health care settings, has taken no antibiotics, was not recently incarcerated, is not immunocompromised, and has not recently traveled. Can we use urine antigen testing to help guide our treatment of this patient's pneumonia?
