Elevated serum acrolein was independently associated with high peripheral arterial stiffness in patients with non-dialysis CKD stages 3-5 (OR 1.015; 95% CI 1.002-1.028; p=0.025).

Does elevated serum acrolein increase the risk of high peripheral arterial stiffness in adults with non-dialysis CKD stages 3-5?
Elevated serum acrolein is independently associated with high peripheral arterial stiffness in patients with non-dialysis CKD stages 3-5, suggesting it may be a marker or mediator of vascular injury in this population.
Effect estimate: OR 1.015 (95% CI 1.002-1.028)
p-value: p=0.025
Background: Arterial stiffness is a major predictor of cardiovascular-related mortality in chronic kidney disease (CKD). While acrolein—an endogenous reactive aldehyde that accumulates with declining renal function—may be linked to vascular injury, its association with high peripheral arterial stiffness (HPAS) remains unclear. Methods: This cross-sectional study used the cardio-ankle vascular index (CAVI) to examine the association between serum acrolein levels and HPAS (CAVI ≥ 9.0) in 204 adults with non-dialysis CKD stages 3–5. Results: HPAS was identified in 90 patients (44.1%) and was associated with a higher prevalence of diabetes (p = 0.047), older age (p = 0.023), higher spot urine protein–creatinine ratio (UPCR, p = 0.046), higher serum fasting glucose (p = 0.041), higher interleukin-6 (p = 0.025), and higher acrolein (p = 0.008). In multivariable logistic regression analysis, serum acrolein (odds ratio, 1.015; 95% confidence interval, 1.002–1.028; p = 0.025), age (p = 0.010), and UPCR (p = 0.046) remained independently associated with HPAS. Log-transformed acrolein was positively correlated with bilateral CAVI (all p < 0.001) and log-transformed UPCR (p < 0.001) but negatively correlated with the estimated glomerular filtration rate (p = 0.001). Conclusions: Elevated serum acrolein is independently associated with HPAS in non-dialysis CKD stages 3–5.
Chang et al. (Fri,) conducted a cross-sectional in Non-dialysis chronic kidney disease stages 3-5 (n=204). Serum acrolein was evaluated on High peripheral arterial stiffness (CAVI ≥ 9.0) (OR 1.015, 95% CI 1.002-1.028, p=0.025). Elevated serum acrolein was independently associated with high peripheral arterial stiffness in patients with non-dialysis CKD stages 3-5 (OR 1.015; 95% CI 1.002-1.028; p=0.025).
