Background: This study aimed to investigate the clinical characteristics and prognosis of refractory peritoneal dialysis (PD)‐associated peritonitis as well as the risk factors of its occurrence and treatment failure. Methods: A single‐center retrospective cohort study was conducted among 519 patients undergoing PD from January 2007 to October 2021. According to the International Society for Peritoneal Dialysis guidelines, all episodes occurred in our center were divided into two groups: refractory and nonrefractory. Demographic, biochemical, and pathogenic bacteria and treatment outcome data were collected. Results: During the 15‐year period, 282 episodes of peritonitis occurred in 166 patients undergoing PD. The refractory rate was 34.0% (96/282). Gram‐positive organisms were the leading cause of peritonitis (47.9%); however, gram‐negative organisms were predominant in refractory peritonitis (34.4%, p = 0.002). Multiple logistic regression revealed that gram‐negative organism‐based peritonitis, longer PD duration, and female sex were the significant independent predictors of refractory peritonitis. Among 96 refractory episodes, white blood cell (WBC) count, dialysate WBC on Day 3, and PD duration ≥5 years were the independent risk factors of treatment failure. Conclusions: Gram‐negative organism‐based peritonitis, longer PD duration, and female sex were the independent risk factors of refractory peritonitis. Refractory peritonitis with higher WBC count, higher dialysate WBC on Day 3, and PD duration ≥5 years increased treatment failure risk and required immediate PD catheter removal. The timely identification of refractory peritonitis with high risk of treatment failure as well as timely PD catheter removal is important. [ABSTRACT FROM AUTHOR] |
