Objective: To investigate the intervention effect of inhibiting excessive reactive oxygen species (ROS) production on renal inflammation, fibrosis, and disease progression in patients with diabetic kidney disease (DKD). Methods: Thirty DKD patients treated at the Department of Nephrology, Hebei University Affiliated Hospital from April 2025 to April 2026 were enrolled as the DKD group. Thirty non-DKD patients from the same period served as the control group. General characteristics and clinical indicators were collected for both groups, including complete blood count, liver and kidney function, electrolytes, blood glucose, and 24-hour urine protein quantification. Serum NLRP3 inflammasome and inflammatory factors (IL-1β, IL-18, TNF-α, IL-6) were measured using ELISA. Transforming growth factor-β (TGF-β) was assessed to evaluate fibrosis severity. Estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI formula. Differences in indicators between groups were compared, and correlations between ROS-related pathway markers and renal function/disease progression endpoints were analyzed. Primary endpoint: eGFR decline ≥ 40% or initiation of dialysis. Secondary endpoints: doubling of random urine albumin-to-creatinine ratio (UACR) or occurrence of cardiovascular events. Results: Patients in the DKD group exhibited significantly higher serum levels of NLRP3, IL-1β, IL-18, TNF-α, IL-6, and TGF-β compared to the control group (p < 0.05). Their eGFR was significant...
