Predictive value of novel nutritional inflammation indexes in IVIG-unresponsive Kawasaki disease: a retrospective
1Department of Pediatrics, Mianyang Central Hospital, School of Medicine, University of Electronic Science and Technology of China, Mianyang, China.
Objective:
This retrospective study aimed to investigate the predictive value of novel albumin-associated nutritional inflammation markers, including the C-reactive protein-albumin-lymphocyte (CALLY) index, C-reactive protein to albumin ratio (CAR), neutrophil-to-albumin ratio (NAR), neutrophil percentage-to-albumin ratio (NPAR) and prognostic nutritional index (PNI), for intravenous immunoglobulin (IVIG) resistance in Kawasaki disease (KD) patients.
Methods:
We conducted a retrospective analysis of clinical data from pediatric patients diagnosed with KD and admitted to our hospital between January 2012 and November 2023. Data were analyzed using univariate analysis, binary logistic regression analysis, and receiver operating curve (ROC) analysis.
Results:
The study included 716 children with KD, and 78 of them (10.9%) were diagnosed with IVIG-resistant KD. CAR, NAR and NPAR were positively correlated with IVIG resistance, while the CALLY index and PNI showed negative correlations. The area under the ROC curve (AUC) values of the CALLY index, CAR, NAR, NPAR and PNI were 0.725, 0.700, 0.580, 0.717 and 0.712.
Conclusion:
Our findings suggest that these novel nutritional inflammation indexes could be useful tools for predicting IVIG resistance in KD patients, potentially guiding timely intensified therapy. Compared to NAR, the CALLY index, CAR, NPAR, and PNI demonstrate stronger predictive performance for intravenous immunoglobulin (IVIG) resistance in Kawasaki disease and may hold greater potential for clinical application.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
