From: SuPAR levels in BAL fluid from patients with acute respiratory distress syndrome—a pilot study
Boxplots of suPAR levels in bronchoalveolar fluid in the study population—bacterial ARDS cohort (n = 16; gray box plot bars), viral ARDS cohort (n = 14; white box plot bars), and control cohort (n = 4; dark-gray box plot bars). Controls received diagnostic routine bronchoscopy and bronchoalveolar lavage, and further diagnostic work-up of suspected pulmonary disease remained inconspicuous. Reasons for bronchoscopy were suspected sarcoidosis in two individuals, chronic cough in one individual, and long-term follow-up bronchoscopy after lung carcinoma resection in one individual. Statistical analyses: p = 0.003 between control and bacterial cohort, p = 0.06 between control and viral cohort, and p = 0.09 between bacterial and viral cohort. ARDS, acute respiratory distress syndrome; BALF, bronchoalveolar fluid; suPAR, soluble urokinase plasminogen activator receptor
