Abstract:
Objective To investigate the prevalence of restless legs syndrome (RLS) in peritoneal dialysis patients and analyze the related risk factors.Methods This study was a cross-sectional study.The patients receiving maintenance peritoneal dialysis from January 2017 to December 2017 in the Peritoneal Dialysis Center of the Second Hospital Affiliated to Soochow University were selected as the study subjects.RLS was screened for peritoneal dialysis patients by epidemiological field investigation based on the RLS diagnostic criteria of the International Restless Leg Syndrome Research Group in 2014.Clinical data and laboratory examinations of selected patients were collected and the differences of clinical indicators between RLS and non-RLS patients were compared.The risk factors related to RLS were analyzed by logistic regression.Results Seventy-six cases of RLS were screened out from 396 PD patients.The prevalence of RLS was 19.2％.Compared with non-RLS group,RLS group patients had longer dialysis age,less 24 hours urine volume,and elevated blood intact Parathormone (iPTH) and alkaline phosphatase (AKP) (all P ＜ 0.05).There was no significant difference in primary disease ratio,sex,age,body mass index,blood pressure,hemoglobin,creatinine,urea nitrogen,uric acid,ferritin,serum iron,transferrin saturation,blood calcium,blood phosphorus,total cholesterol,triglyceride,low density lipoprotein,high density lipoprotein,eGFR,Kt/V,Ccr between RLS and non-RLS group patients (all P ＞ 0.05).Multivariate logistic regression analysis showed that long dialysis age (OR=1.010,95％CI 1.001-1.018,P=0.022) and high blood AKP (OR=1.005,95％CI 1.001-1.010,P=0.021) were independent risk factors for RLS in peritoneal dialysis patients (both P ＜ 0.05).Conclusions The prevalence of RLS is high in peritoneal dialysis patients.Long dialysis age and high blood AKP are independent risk factors for RLS.
