论文摘要: Background  To evaluate the association of dialysate interleukin-6 (IL-6), representing local subclinical intraperitoneal inflammation, with the long-term peritonitis-free survival in continuous ambulatory peritoneal dialysis (CAPD) patients.
Methods  Stable CAPD patients were enrolled in this prospective study with up to 7 years of follow-up. IL-6 concentration in the overnight effluent was determined and expressed as the IL-6 appearance rate (IL-6AR).  Patients were divided into two groups according to IL-6AR and prospectively followed up until death, cessation of PD or to the end of the study. Date and number of peritonitis episodes were recorded carefully and the utility of IL-6 AR in predicting peritonitis-free survival was analyzed using Kaplan-meier and Cox proportional hazards model.
Results  A total of 149 patients were enrolled, including 72 males (48.2%) with mean age 57.2±13.6 years and median PD duration 22 (5.9,45.5) months. By the end of the study, 137 episodes of peritonitis were occurred in 91 patients. Peritonitis rates were 0.24 episodes per patient-year in the low IL-6AR group and 0.21 episodes per patient-year in the high IL-6AR group, respectively. Compared to patients who did not suffer peritonitis, patients occured peritonitis had higher levels of IL-6AR [278.1(247.7,303.7)vs. 261.7(48.9,287.6) pg/min, p = 0.024]. Patients in the high IL-6AR group showed a significantly inferior peritonitis-free survival when compared with their counterparts in the low IL-6AR group[48.8 vs. 67.7 months, Log-Rank=4.98, p=0.026]. A multivariable Cox proportional hazards analysis found that both high dialysate IL-6AR [HR 1.002  and 95% CI (1.000-1.003), p = 0.038] and older age [HR 1.025 and 95% CI  (1.006-1.044), p = 0.008] were independent risk factors for peritonitis-free survival. However, IL-6 AR was not a predictor for patient survival and technique survival in this cohort.
Conclusions  This prospective study suggests that intraperitoneal IL-6 is a potent predictor of long-term peritonitis-free survival in patients undergoing peritoneal dialysis.
