Resum: Colistin has a narrow therapeutic window with nephrotoxicity being the major dose-limiting adverse effect. Currently, the optimal doses and therapeutic plasma levels are unknown. Prospective observational cohort study, including patients infected by colistin-susceptible P. aeruginosa treated with intravenous colistimethate sodium (CMS). Clinical data and colistin plasma levels at steady-state (C) were recorded. The primary and secondary end points were clinical cure and 30-day all-cause mortality. Ninety-one patients were included. Clinical cure was observed in 72 (79%) patients. The mean (SD) C was 1. 49 (1. 4) mg/L and 2. 42 (1. 5) mg/L (p = 0. 01) in patients who achieved clinical cure and those who not, respectively. Independent risk factors for clinical failure were male sex (OR 5. 88; 95% CI 1. 09-31. 63), APACHE II score (OR 1. 15; 95% CI 1. 03-1. 27) and nephrotoxicity at the EOT (OR 9. 13; 95% CI 95% 2. 06-40. 5). The 30-day mortality rate was 30. 8%. Risk factors for 30-day mortality included the APACHE II score (OR 1. 98; 95% CI 1-1. 20), the McCabe score (OR 2. 49; 95% CI 1. 14-5. 43) and the presence of nephrotoxicity at the end of treatment (EOT) (OR 3. 8; 95% CI 1. 26-11. 47). In this series of patients with infections caused by XDR P. aeruginosa infections, C is not observed to be related to clinical outcome.
