A total of 2043 T2DM patients undergoing coronary angiography or intervention at Nanjing First Hospital (2021-2023) were retrospectively analyzed. Multivariable logistic regression identified independent risk factors, and receiver operating characteristic curves assessed predictive performance. CI-AKI occurred in 13.4% of patients. Female sex, elevated systolic blood pressure, increased neutrophil count, hyperglycemia, hematuria, diuretic use, and lower GNRI and PNI were independently associated with CI-AKI. Among the nutritional indices, PNI had the highest predictive value (AUC\u2009=\u2009.871), outperforming GNRI (AUC\u2009=\u2009.755) and CONUT (AUC\u2009=\u2009.547). Combining PNI or GNRI with clinical variables further improved predictive accuracy (AUC\u2009=\u2009.899 and .818, respectively). Restricted cubic spline analysis revealed nonlinear risk thresholds (PNI\u2009&lt;38, GNRI\u2009&lt;\u200992). GNRI and PNI are effective predictors of CI-AKI and may aid in early risk stratification and clinical intervention among T2DM patients, with PNI demonstrating superior performance.<\/jats:p>","DOI":"10.1177\/00033197251399868","type":"journal-article","created":{"date-parts":[[2026,1,29]],"date-time":"2026-01-29T11:26:23Z","timestamp":1769685983000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Predictive Value of Nutritional Scores for Contrast-Induced Acute Kidney Injury in Patients with Type 2 Diabetes Mellitus"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-9090-6264","authenticated-orcid":false,"given":"Xia","family":"Du","sequence":"first","affiliation":[{"name":"Department of Nephrology, Sir Run Run Hospital, Nanjing Medical University, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruihan","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Sir Run Run Hospital, Nanjing Medical University, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danning","family":"Guo","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Xuzhou First People\u2019s Hospital, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziyi","family":"Qiu","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Sir Run Run Hospital, Nanjing Medical University, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhuo","family":"Zhen","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Nanjing First Hospital, Nanjing Medical University, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4024-6684","authenticated-orcid":false,"given":"Mengqing","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Nanjing First Hospital, Nanjing Medical University, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changchun","family":"Cao","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Sir Run Run Hospital, Nanjing Medical University, Jiangsu, China"},{"name":"Department of Nephrology, Nanjing First Hospital, Nanjing Medical University, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,1,29]]},"reference":[{"key":"e_1_3_3_2_2","first-page":"299","article-title":"Contrast-induced acute kidney injury-definitions, epidemiology, and implications","volume":"9","author":"Azzalini L","year":"2020","unstructured":"Azzalini L, Kalra S.
