Case PresentationA 78-year-old man with asthma and COPD presented with shortness of breath, cough, and severe malaise for 4 days. Upon arrival, the patient was conscious and body temperature was 37.5°C. Arterial oxygen saturation (Spo2) was 80% on room air. Laboratory data demonstrated a WBC count of 17,400/μL (89.5% neutrophils) and C-reactive protein of 5.00 mg/dL. CT scan of chest revealed scattered ground-glass in the upper right lobe and thickening of the bronchial wall. Based on these findings, acute bronchopneumonia was diagnosed and antibacterial therapy was started. The day after admission, the patient's general condition and shortness of breath had gradually improved. We treated and observed him carefully for 10 days in the hospital on antibacterial therapy because of his underlying comorbidities (asthma and COPD) and his ongoing hypoxemia. Three days after discharge, the patient re-presented with shortness of breath, hypoxemia, and loss of appetite. The patient was hospitalized for a second time.Copyright © 2019.
