Inflammation-based scores predict chronic kidney disease progression in patients with chronic kidney disease and chronic heart failure

Inflammation is associated with adverse outcomes of chronic kidney disease (CKD) or chronic heart failure (CHF), but few large data exist. We aimed to explore the clinical associations, and prognostic consequences of inflammation-based scores in patients with CKD and CHF. This work was a retrospective cohort study. Glasgow Prognostic Score (GPS), modified Glasgow Prognostic Score (mGPS), Prognostic Nutritional Index (PNI) and Prognostic Index (PI), were used to explore its relationship with CKD progression in patients with CKD stage 1-3b and CHF from the China Renal Data System (CRDS). The composite end point of this study was CKD progression which was defined as eGFR reduction of 40% or progression to end stage renal disease (ESRD). Of 8491 patients were enrolled. Kaplan-Meier curve showed that compared to the lower inflammation-based scores, the increased scores have a higher rate of CKD progression, whether in GPS, mGPS, PNI or PI (log-rank test,
