We studied 180 adults, 90 patients with type 2 diabetes and diabetic nephropathy and 90 patients on hemodialysis. We measured serum advanced oxidation protein products (AOPP) and thiobarbituric acid reactive substances (TBARS) by enzyme-linked immunosorbent assay (ELISA). Partial correlations were adjusted for age, sex, and albumin with false discovery rate (FDR) control. Principal component analysis (PCA) summarized inflammatory indices and linear models tested predictors of AOPP and TBARS. Oxidative damage was higher in hemodialysis, with AOPP median 25.80 versus 5.06 and TBARS 8.49 versus 1.89, p less than 0.0001. C reactive protein (CRP) and mean corpuscular volume-to-lymphocyte ratio (MCVL) were higher in patients ongoing hemodialysis; systemic immune-inflammation index (SII) was higher in diabetic nephropathy. PCA yielded a dominant inflammation axis in both cohorts, 74.73 percent in hemodialysis and 85.20 percent in diabetic nephropathy. In regression, creatinine (\u03b2 = 2.47, p = 0.026) predicted AOPP in hemodialysis. Dialysis vintage inversely predicted TBARS, \u03b2 = \u22120.2305, p = 0.0209. In diabetic nephropathy, the PCA inflammation score predicted AOPP, \u03b2 = 1.134, p = 0.0003. Protein oxidation tracked systemic inflammation in diabetic nephropathy, but not in hemodialysis. AOPP outperformed TBARS as an inflammatory partner and a practical monitoring candidate in diabetic kidney disease. Prospective studies should test for prognostic value and therapy sensitivity.<\/jats:p>","DOI":"10.3390\/ijms262110670","type":"journal-article","created":{"date-parts":[[2025,11,3]],"date-time":"2025-11-03T13:15:14Z","timestamp":1762175714000},"page":"10670","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Assessment of AOPP, TBARS, and Inflammatory Status in Diabetic Nephropathy and Hemodialyzed Patients"],"prefix":"10.3390","volume":"26","author":[{"given":"Daniel Cosmin","family":"Caragea","sequence":"first","affiliation":[{"name":"Department of Nephrology, Faculty of Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4817-1365","authenticated-orcid":false,"given":"Lidia","family":"Boldeanu","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Faculty of Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-3146-8769","authenticated-orcid":false,"given":"Mohamed-Zakaria","family":"Assani","sequence":"additional","affiliation":[{"name":"Doctoral School, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"},{"name":"Department of Immunology, Faculty of Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariana-Emilia","family":"Caragea","sequence":"additional","affiliation":[{"name":"Doctoral School, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra-\u0218tefania","family":"Stroe-Ionescu","sequence":"additional","affiliation":[{"name":"Doctoral School, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Romeo","family":"Popa","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-3410-1334","authenticated-orcid":false,"given":"Daniela-Teodora","family":"Maria","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Faculty of Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7398-5689","authenticated-orcid":false,"given":"Vlad","family":"P\u0103dureanu","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristin Constantin","family":"Vere","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2481-6138","authenticated-orcid":false,"given":"Mihail Virgil","family":"Boldeanu","sequence":"additional","affiliation":[{"name":"Department of Immunology, Faculty of Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,1]]},"reference":[{"key":"ref_1","first-page":"5478708","article-title":"Oxidative Stress in the Pathophysiology of Kidney Disease: Implications for Noninvasive Monitoring and Identification of Biomarkers","volume":"2020","year":"2020","journal-title":"Oxid.
