Özet

© 2016, Oman Medical Specialty Board. All rights reserved.Objectives: We investigated the incidence of and risk factors for nephrotoxicity in patients using intravenous colistin. Methods: This retrospective, observational study was conducted at Karadeniz Technical University, Faculty of Medicine, clinics and intensive care unit between 1 January 2009 and 1 January 2013. Intravenous colistin was administered to 133 patients at a dose of 2.5-5.0 mg/kg/day. Results: The patients mean age was 54.3±19.1 years and the mean duration of treatment was 13.5±3.6 days. Nephrotoxicity developed in 5.0±2.8 days in 38 (28.6%) patients. Based on RIFLE (risk, injury, failure, loss of kidney function, and end-stage kidney disease) criteria, 15 (39.5%) patients were class 1, 17 (44.7%) were class 2, six (15.8%) were class 3, and none were class 4. The mean duration of development of nephrotoxicity was 5.0±2.8 days. Hemodialysis requirement was observed in two (5.2%) of the 38 patients who developed nephrotoxicity. In these cases, colistin therapy was not discontinued. Nephrotoxicity was correlated with advanced age, high pretreatment serum creatinine levels, diabetes mellitus, and chronic obstructive pulmonary disease. Conclusions: The use of colistin is relatively safe for patients that have normal renal functions. However, better standardization of the definition of nephrotoxicity in those patients with the use of scoring systems and close monitoring are necessary.
