Abstract

Background: Previous studies have proved that irisin is related to the development of chronic kidney disease. In this study, we aimed to compare serum irisin level in patients treated with peritoneal dialysis (PD) and hemodialysis (HD).

Methods: Two hundred and fifty-two dialysis patients (146 PD patients and 106 HD patients) were included in the study. Levels of serum irisin and other parameters were compared between the two groups' patients.

Results: There were higher serum irisin levels in PD patients than those in HD patients [113.10 (106.15 ~ 119.15) ng/ml vs. 45.72(21.67 ~ 79.71) ng/ml, P < 0.001]. Moreover, body fat mass, percent body fat, serum calcium, high-density lipoprotein, low-density lipoprotein, carbon dioxide combining power (CO2CP) and residual renal function were higher in patients on PD than that in those on HD, whereas levels of lean body mass, systolic blood pressure, albumin, serum uric acid, potassium, and phosphorus（It should be "were" replace are) are higher in HD patients in comparison to PD patients. Dialysis modality (PD/HD), serum CO2CP level, lean body mass, and percent body fat independently positively correlated with natural logarithm of irisin (lnirisin) by multivariate linear regression analysis.

Conclusions: In this study, we prove that serum irisin level is significantly higher in patients treated with peritoneal dialysis than that with hemodialysis. As well as, increasing skeletal muscle mass and fat body percent, and correcting metabolic acidosis may increase serum irisin levels.
