Serum procalcitonin level predict acute kidney injury following traumatic brain injury.

Abstract Background As a common non-neurologic complication following traumatic brain injury (TBI), acute kidney injury (AKI) is a risk factor of mortality. Some studies confirmed the predictive value of procalcitonin (PCT) on AKI in several clinical settings. We designed this study to explore the predictive value of PCT on AKI following TBI. Methods We retrospectively enrolled patients admitted to our hospital with TBI from February 2015 to June 2019. Multivariate logistic regression analysis was performed to find risk factors of AKI and construct predictive model for AKI. Receiver operating characteristics (ROC) curves were drawn to compare the predictive value of PCT and constructed model. Results A total of 214 patients was included in this study. The incidence of AKI following TBI was 25.70% in this study. Compared with non-AKI group, AKI group had higher age (P =0.031), lower GCS (P Conclusions PCT is valuable in predicting AKI following TBI. Try to avoid AKI following TBI, physicians can adjust treatment strategies according to the level of PCT.
