    Abstract:
    The objective of this study was to evaluate the impact of polymyxin B (PMB) -associated acute kidney injury (AKI) in 1-year mortality and renal function recovery. Patients >18 years old who survived the first 30 days after PMB therapy were followed for 1 year. The impact of AKI and renal failure (using RIFLE score) in 1-year mortality was analysed, along with other confounding variables. Variables with a P-value ≤0.2 were included in a forward stepwise Cox regression model. In the subgroup of patients who developed AKI, we evaluated renal function recovery. A total of 234 patients were included for analyses. Of these, 108 (46.1%) died, in a median time of 63 (38.3-102.5) days. The use of other nephrotoxic drugs along with PMB (P = 0.05), renal failure (P = 0.03), dialysis (P < 0.01) and re-exposure to PMB (P<0.01), were all significantly related to 1-year mortality, while male gender had a protective effect (P = 0.01). Independent factors related to death were age (adjusted hazard ratio (aHR) 1.02, 95% confidence interval (CI) 1.00-1.03, P = 0.02), re-exposure to PMB (aHR 2.69, 95% CI 1.82-3.95, P<0.01), and male gender (aHR0.6, 95% CI 0.41-0.87, P = 0.01), when controlled for renal failure (aHR 1.28, 95% CI 0.78-2.10, P = 0.34).Thirty one of 94 (33%) patients who developed AKI had renal function recovery within 1 year. Mortality rates were high in the first year after PMB use and only one-third of patients who developed AKI returned to baseline renal function. Strategies to reduce renal toxicity are urgently needed in these patients.
