title: Serial changes of interleukin-6 and interleukin-8 levels in drain dialysate of uremic patients with continuous ambulatory peritoneal dialysis during peritonitis.
abstract: In this study, we investigated whether peritoneal dialysate interleukin-6 (IL-6) and IL-8 levels were elevated during peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients, with special reference to the high peritonitis occurrence (HPO) group. Serial measurements of IL-6 and IL-8 levels in dialysate before, during and after resolution of peritonitis were done in 13 CAPD patients with 15 episodes of peritonitis. Based on the peritonitis occurrence, 7 patients were assigned to the low peritonitis occurrence (LPO) and 6 patients to the HPO group. Marked elevation of IL-6 and IL-8 in drain dialysate occurred in the early period of peritonitis especially on the first 2 days in both groups. However, there were no significant differences between the groups in the levels of IL-6 and IL-8 in drain dialysate on the first day of peritonitis. However, the disappearance of peritoneal dialysate IL-8 level was faster in the LPO than in the HPO group. The decrease in IL-8 levels during peritonitis was faster than that of IL-6. Marked elevation of IL-6 and IL-8 in drain dialysate was found in the patient with peritonitis caused by Staphylococcus epidermidis and mixed gram-negative bacilli. Therefore, we hypothesize that when peritonitis occurs too frequently in a short period in the HPO group, more IL-6 and IL-8 have been produced in the peritoneum contributing to the ongoing peritoneal injury and/or fibrosis.
