Abstract
UNLABELLED: ♦ BACKGROUND: To investigate patient survival and technical failure of patients with prior stroke receiving continuous ambulatory peritoneal dialysis (CAPD) in Southern China. ♦ METHODS: This was a retrospective study. All subjects were recruited from the peritoneal dialysis center in The First Affiliated Hospital of Sun Yat-sen University from 1 January 2006 to 31 December 2010. All eligible patients were assigned to stroke group and non-stroke group according to a history of stroke before receiving CAPD. The primary outcomes were all-cause mortality and death-censored technical failure. Cox regression was used to estimate risk factors of all-cause mortality and death-censored technique failure. ♦ RESULTS: Of the 1,068 recruited patients, 75 (7.0%) patients had a previous history of stroke. The all-cause mortality and death-censored technique failure were significantly higher in the stroke group compared with the non-stroke group, respectively (odds ratio [OR] 2.67, 95% confidence interval [CI] 1.59 - 4.46 and OR 2.52, 95% CI 1.19 - 5.34). Older age (changed by 10 years, hazard ratio [HR] 1.90, 95% CI 1.07 - 3.38), lower body mass index (BMI 18.5 - 23.9 vs < 18.5 kg/m(2) reference, HR 0.17, 95% CI 0.05 - 0.55) and time to the first episode of peritonitis (HR 0.93, 95% CI 0.89 - 0.96) were independently associated with increased risk of all-cause mortality in patients with prior stroke. In addition, time to the first episode of peritonitis was associated with decreased risk of death-censored technique failure (HR 0.91, 95% CI 0.84 - 0.99) in those with prior stroke. ♦ CONCLUSIONS: Continuous ambulatory peritoneal dialysis patients with prior stroke had high rates of all-cause mortality and technique failure compared with those without prior stroke. Older age, lower BMI, and time to the first episode of peritonitis were independent risk factors of all-cause mortality in patients with prior stroke.
