Lack of expression of interleukin 8 and RANTES in autoimmune bullous skin diseases.

OBJECTIVE

The study investigates value of preoperative prognostic nutritional index (PNI) combined with N-terminal pro-brain natriuretic peptide (NT-proBNP) in predicting postoperative acute kidney injury (AKI) in congenital heart disease (CHD) children.

METHODS

The clinical data of 108 children with congenital heart disease were retrospectively collected. According to whether AKI occurred 48 h after operation, they were divided into AKI group (n = 32) and non-AKI group (n = 76). The clinical data, preoperative PNI and NT-proBNP levels were compared between the two groups. Multivariate logistic regression analysis was used to analyze the influencing factors of AKI, and the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of preoperative PNI, NT-proBNP and their combination.

RESULTS

Multivariate logistic regression analysis showed that Scr, PNI and NT-proBNP were independent risk factors for postoperative AKI in children with congenital heart disease (P < 0.001). The results of ROC curve analysis showed that the area under the curve (AUC) of preoperative PNI, NT-proBNP and their combination in predicting postoperative AKI in children with congenital heart disease were 0.839, 0.738 and 0.907, respectively, and the AUC of their combination was the highest.

CONCLUSION

The combined use of preoperative PNI as well as NT-proBNP holds significant value in predicting postoperative AKI in CHD children. Monitoring preoperative PNI and NT-proBNP levels may aid in clinically identifying the risk of postoperative AKI in CHD children, thereby improving their prognosis.
