B71-11 Hot Tub Pneumonia
Abstract
Abstract Introduction Hot tub associated pneumonia is an uncommon respiratory infection caused by inhalation of aerosolized pathogens from hot tubs. Legionella species, nontuberculous mycobacteria (NTM), and Pseudomonas aeruginosa are among the most frequently implicated organisms. Such infections can mimic or exacerbate underlying respiratory conditions, particularly asthma, and are often underdiagnosed due to nonspecific clinical and radiologic findings. We present a case of hot tub associated pneumonia. Case Presentation A 64-year-old male with a history of asthma presented with a five-day history of progressive shortness of breath, cough, and wheezing, requiring 4 L/min of supplemental oxygen via nasal cannula. The patient reported multiple recurrent hospitalizations and emergency department (ED) visits over the past six months for episodes of pneumonia necessitating antibiotic therapy. He had been evaluated in the ED two days prior for similar symptoms. At that time, a chest radiograph was unremarkable; however, a computed tomography (CT) scan of the chest demonstrated mild patchy airspace opacities with bilateral lower lobe bronchitis. He was discharged home on oral amoxicillin-clavulanate (875 mg twice daily), but his symptoms persisted and progressively worsened, with increased cough, wheezing, and dyspnea. On examination, expiratory wheezes were appreciated bilaterally. Further history revealed that the onset of symptoms coincided with the recent installation of a…
