- Brief Summary
INTRODUCTION AND AIMS: The aims of this study were to evaluate patient and technique survival rates, investigate peritonitis rates and evaluate factors affecting mortality in peritoneal dialysis (PD) patients over a period of 20 years at Istanbul Faculty of Medicine Peritoneal Dialysis Unit.
METHODS: Two hundred seventy seven patients have received PD as renal replacement therapy (RRT) over a period of 20 years. After exclusion of patients with follow-up shorter than 3 months and patients whose data were not available, 250 patients were examined retrospectively. Data for sex, age, primary disease, comorbidities, follow up duration, cause of death, and cause of technique failure were collected from medical records.
- Detailed Description
Material and Method All patients 18 years of age and older who were treated with PD at the Istanbul Medical Faculty from October 1994 to October 2014 were included in the study. Patients exclude which follow-up shorter than 3 months and patients whose data were not available. From the day PD was started, all peritonitis data were collected prospectively in a large database. The data include Socio-demographic data, type of peritoneal dialysis, starting time and duration of every peritonitis episode, causative organisms and outcome of the peritonitis, which could be cure, change of PD catheter, transfer to hemodialysis, or death. The time in months from PD start to the first episode of peritonitis was computed.
Primary kidney disease was classified into 9 main categories according to the codes of the European Renal Association - European Dialysis and Transplant Association. Peritonitis in PD was defined as a peritoneal dialysate effluent containing \>100 white blood cells/mL, of which \>50% were polymorphonuclear leukocytes. Patients with two or more pathogens isolated from the cultures in a peritonitis episode were considered to have polymicrobial peritonitis. A relapse of peritonitis was defined when the same organism or a culture-negative peritonitis episode was identified within 4 weeks of completing appropriate antibiotic therapy for a previous episode.
Socio-demographic, clinical and treatment characteristics, medium (standard deviation for continuous variables) or median (25th and 75th percentages); number for categorical variables (rate) were calculated. Cox regression analysis applied to examine the impact of demographic and clinical features of periton dialysis patients . Chi-square test for categorical variables used. Univariate and multivariate analyzes calculated using the Kruskal-Wallis or Mann-Whitney test method. P-value was \<0.05 for as long as it is considered statistically significant. The evaluation of the results obtained using SPSS 21.0 software.
