Dysregulation of innate immunity has been proposed as an important contributing factor for advanced atherosclerosis and resultant high mortality in hemodialysis (HD) patients. To evaluate the long-term prognostic role of in vivo neutrophil extracellular traps (NETs), we measured circulating serum nucleosome, myeloperoxidase (MPO), and DNase I levels in 281 incident HD patients. Circulating nucleosome level was significantly higher in HD patients compared to controls, and it was closely associated with MPO levels, suggesting increased in vivo NETs in uremia. Patients in the nucleosome Q4 group had significantly increased all-cause and adverse CV mortality compared to those in the Q1–3 group even after adjusting traditional risk factors Also, serum DNase I level was significantly higher in HD patients than controls (2.76 ± 1.02 ng/ml and 1.93 ± 0.85 ng/ml), but it had no correlation with NETs. Interestingly, it serves an additive biomarker for predicting poor CV outcomes. The two novel biomarkers might provide an importance independent prognostic significance in incident HD patients.
