Abstract:
This study investigated the predictive value of the C-reactive protein-albumin-lymphocyte (CALLY) index for stroke-associated pneumonia (SAP) in 209 patients with spontaneous intracerebral hemorrhage (ICH), who were categorized into SAP and non-SAP groups. Results revealed significantly lower CALLY index levels in the SAP group, with negative correlations observed between the CALLY index and neutrophil count, monocyte count, neutrophil-to-lymphocyte ratio (NLR), clinical pulmonary infection scores (CPIS), and controlling nutritional status (CONUT) scores. The receiver-operating characteristic (ROC) analysis demonstrated the high predictive accuracy of the CALLY index for SAP, comparable to NLR and CONUT scores. The Kaplan-Meier analysis indicated a markedly higher SAP risk in patients with a low CALLY index, and multivariate COX regression confirmed a low CALLY index as an independent risk factor. Overall, a reduced CALLY index effectively predicts SAP in ICH patients. However, this conclusion requires further external validation.
