Methods: In a prospective study, we assessed whether 16 plasma and 10 urine cytokine levels can inform the residual risk of CKD progression in 93 incident patients with DKD treated by nephrology according to clinical guidelines. Results: Plasma and urine levels of 12 plasma and 7 urinary cytokines differed between patients with DKD and from healthy controls. Participants were categorized into CKD G1\u2013G2 (preserved GFR) and CKD G3\u2013G5 (GFR &lt;60 mL\/min\/1.73 m2). After a median of 7.27 years (interquartile range, 5.34\u20139.56), 13\/40 (32.5%) patients with CKD G1\u2013G2 at baseline had progressed to CKD G3\u2013G5. Progressors had higher plasma interleukin 22 (IL-22) and tumor necrosis factor-alpha (TNF-\u03b1) levels than nonprogressors. Plasma IL-22 and TNF-\u03b1 levels in progressors were similar to those in patients already in CKD G3\u2013G5 at baseline, suggesting that cytokine dysregulation precedes CKD progression. In patients with CKD G1\u2013G2, cutoff points for plasma IL-22 and TNF-\u03b1 predicted progression with an area under the curve of 0.76 and 0.77, respectively. Additionally, patients with CKD G1\u2013G2 and plasma TNF-\u03b1 or IL-22 levels equal to or above the cutoff value had significantly lower estimated glomerular filtration rate values at the end of follow-up and had more frequently progressed to a very high-risk KDIGO category. In cluster analysis, clusters displaying the highest urinary or plasma cytokine levels were associated with worse GFR outcomes. Conclusion: Plasma IL-22 and TNF-\u03b1 may help identify patients with early DKD with a high residual risk of CKD progression despite treatment.<\/jats:p>","DOI":"10.1159\/000547738","type":"journal-article","created":{"date-parts":[[2025,9,8]],"date-time":"2025-09-08T16:00:46Z","timestamp":1757347246000},"page":"528-540","source":"Crossref","is-referenced-by-count":2,"title":["Plasma
