Abstract:
Objective:To explore the correlation between serum 25-hydroxyvitamin D3 [25(OH)D3] level and peritoneal dialysis (PD) associated peritonitis, and provide a new idea for the prevention and treatment of peritonitis.Methods:In this single-center retrospective cohort study, patients who were≥18 years old and were treated with regular PD≥3 months in PD center from January 1, 2014 to September 30, 2018 were recruited, except those who had a history of malignant tumors or systemic infectious diseases, transferred from permanent hemodialysis (HD) or failed kidney transplantation. Baseline data including demographic characteristics as well as clinical and biochemical data were collected. All the patients were followed up until death, transfer to HD, kidney transplantation, transfer to other centers or the end of our study (December 31, 2018), and were divided into low tertile [serum 25(OH)D3 ≤12μg/L], middle tertile[12 μg/L17 μg/L] according to the baseline serum 25(OH)D3 level. Multivariate adjusted Poisson model was used to evaluate the association between serum 25(OH)D3 level and PD related peritonitis.Results:A total of 642 patients were enrolled in our study, of whom 341 were male (53.12%) , and the age was (47.58±14.10) years old. The serum 25(OH)D3 level was (13.83±6.41) μg/L. As for the primary disease, 67.19% were chronic glomerulonephritis. During a median 42(19, 59) months follow-up period, 232 peritonitis occurred in 139 patients. After adjusting for confounders, including gender, age, albumin, body mass index(BMI), calcium-phosphorus product, intact parathyroid hormone (iPTH), diabetes, charlson index and drug use, multivariate Poisson regression analysis showed that the risk of peritonitis in the middle tertile and the low tertile was 92% (95% CI 0.62-1.38, P= 0.690) and 1.74 times (95% CI 1.19-2.54, P=0.004) of the high tertile respectively. The difference between the low tertile and the high tertile was statistically significant. Conclusions:The level of serum 25(OH)D3 is closely related to the occurrence of PD associated peritonitis. Low level serum 25(OH)D3 is an independent risk factor for peritonitis in PD patients.
