Background

Hyperchloremia is associated with increased mortality in pediatric septic shock patients, and associated with increased rate of acute kidney injury (AKI) in adults. It is unknown whether hyperchloremia is associated with AKI in pediatric patients.

Methods

We tested the hypothesis that hyperchloremia is associated with increased rates of severe AKI in pediatric patients with septic shock. We performed a retrospective analysis of a pediatric septic shock database that included 619 children with septic shock from 29 PICUs in the U.S. We considered the minimum, maximum, and mean chloride values as separate hyperchloremia variables within the first 7 days of PICU admission. We considered hyperchloremia as a dichotomized variable defined a priori as a serum concentration ≥110mmol/L. We used multivariable logistic regression to determine the association between these hyperchloremia variables and outcomes, after adjusting for illness severity and age. Our primary outcome variable was day 3 AKI, defined as KDIGO stage 2 or 3.

Results

There were 125 subjects with AKI and 494 subjects with no AKI. Subjects with AKI were younger (1.7 years; IQR 0.7-5.4 v. 3.5 years; IQR 1.3-7.1; p <0.001) and had higher PRISM-III scores (15; IQR 9-24 v. 11; IQR 7-16; p <0.001). There were 42 subjects with a minimum chloride ≥110mmol/L, 117 subjects with a mean chloride ≥110mmol/L, and 359 subjects with a maximum chloride ≥110mmol/L. A minimum chloride ≥110mmol/L was associated with increased odds of AKI (odds ratio, 2.4; 95% CI, 1.2-4.9; p = 0.014). A mean chloride ≥110mmol/L was associated with increased odds of AKI (odds ratio, 1.8; 95% CI, 1.1-2.9; p = 0.014).

Conclusion

Hyperchloremia is independently associated with severe AKI in pediatric patients with septic shock. Further evaluation of the optimal fluid to be used in resuscitation of these patients is warranted.
