Clinical and biochemical data, including serum lipase, Scr, and BUN were collected. Additionally, a supplementary cohort of 50 CKD patients treated between January 2024 and March 2025 was included to support the findings.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>Serum lipase levels increased with advancing CKD stages [G1-2: 40.50 (30.75,52.00), G3:47.00 (37.25,61.00), G4:100.00 (77.00,126.00), G5:155.50 (126.75,243.75), (P\u2009&lt;\u20090.05), showing a positive correlation with Scr (r\u2009=\u20090.714, P\u2009&lt;\u20090.001) and BUN ((r\u2009=\u20090.678, P\u2009&lt;\u20090.001). Univariate logistic regression analysis indicated that age, Scr, BUN, and serum lipase were positively associated with CKD stages, whereas HDL-C exhibited negative correlations. Multivariate logistic regression analysis identified several associated factors of CKD stages, including Scr (OR=1.01; 95% CI 1.01\u20131.02; P\u2009&lt;\u20090.001), BUN (OR=1.17; 95% CI 1.07\u20131.29; P\u2009&lt;\u20090.001), age (OR=1.03; 95% CI 1.01\u20131.05; P\u2009=\u20090.019), and serum lipase (OR=1.02, 95% CI 1.01\u20131.03, P\u2009&lt;\u20090.001). Serum lipase\u2019s AUC for distinguishing CKD stages G1-2 vs. G3, G3 vs. G4, and G4 vs. G5 were 0.64 (0.55\u20130.73), 0.89 (0.83\u20130.94), and 0.84 (0.75\u20130.93), respectively, with validation cohort AUCs of 0.65 (0.45\u20130.85), 0.82 (0.62\u20131.00), and 0.86 (0.65\u20131.00).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Serum lipase emerges as a novel biomarker for CKD stages, exhibiting stage-dependent increases and independent prognostic significance.
