The use of vasopressors is linked to acute kidney injury (AKI) in patients treated with colistin. This finding promotes safer colistin use in intensive care units for multidrug-resistant infections.
Area of Science:
- Nephrology
- Infectious Diseases
- Critical Care Medicine
Background:
- Colistin is crucial for treating multidrug-resistant Gram-negative bacterial infections.
- Colistin-induced acute kidney injury (AKI) is a significant concern in intensive care units.
- Identifying risk factors for colistin-induced AKI is essential for patient safety.
Purpose of the Study:
- To determine risk factors associated with colistin-induced AKI.
- To promote safer colistin administration in intensive care settings.
- To guide clinical practice for managing infections caused by multidrug-resistant pathogens.
Main Methods:
- Retrospective observational study of adult patients receiving intravenous colistin for at least 48 hours.
- Data collected from January 2020 to December 2020 in a tertiary care hospital's intensive care unit.
- AKI diagnosis and staging based on Kidney Disease Improving Global Outcome (KDIGO) criteria.
Main Results:
- 54 out of 148 patients (36%) developed AKI during colistin treatment.
- Univariate analysis identified age, comorbidity index, APACHE II score, colistin duration, baseline creatinine, vasopressor use, and vancomycin as significant risk factors.
- Multivariate analysis revealed vasopressor use as an independent predictor of AKI (OR: 3.14, p=0.06).
Conclusions:
- Vasopressor use is independently associated with AKI in critically ill patients undergoing colistin therapy.
- This finding highlights the need for careful monitoring of kidney function in patients receiving both colistin and vasopressors.
- Results support the development of strategies to mitigate AKI risk during colistin treatment.
