RESUMEN
Objective@#To discuss the neuroimaging characteristics of transcranial ultrasound in end-stage renal disease (ESRD) with restless legs syndrome.@*Methods@#Transcranial sonography (TCS) was performed in ESRD with restless legs syndrome (RLS+ group, n=41), ESRD without restless legs syndrome (RLS- group, n=57) and control group (n=47), who were enrolled in the Second Affiliated Hospital of Soochow University from January 2017 to December 2018.

RESUMEN
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.
RESUMEN
Objective To analyze the therapeutic effect and prognosis of peritoneal dialysis in patients with end-stage polycystic kidney disease.Methods A retrospective analysis was performed on patients with polycystic kidney disease who were treated with peritoneal dialysis for more than 3 months between July 2007 and September 2016 in the Second Hospital Affiliated to Soochow University.A total of 45 patients were enrolled in this study.Another 45 patients of non-diabetic nephropathy were selected as the control group matched by gender,age,and time of PD initiation.The information of the two groups such as general data,dialysis related complications,incidence of peritonitis,prognosis was recorded.Survival analysis was performed using the Kaplan-Meier method and Log-rank test.The risk factors affecting patients' survival were analyzed with Cox regression model.Results There were no significant difference in pre-dialysis age,sex ratio,blood pressure,urine volume,body weight,eGFR,biochemical data,and the proportion of hypertension and diabetes mellitus in the polycystic kidney group and control group.24 h ultra-filtration volume,4 h D/Pcr,Kt/V and Ccr between the two groups showed no significant difference (all P ＞ 0.05).The incidence of peritonitis and the time of the first peritonitis in the two groups respectively as one episode per 82.4 months vs one episode per 81.5 months,(35.8±22.8) months vs (34.5±20.9) months had no statistical difference.The ratio of hernia (6.6％ vs 2.2％),thoracic and abdominal leakage (4.4％ vs 2.2％),dialysate leakage (0 vs 0),catheter dysfunction (4.4％ vs 6.6％),exit-site infections (11.1％ vs 6.6％),tunnel infections (4.4％ vs 2.2％) and non PD related infections (11.1％ vs 13.3％) had no significant difference.The 1-year,3-year,5-year patient survival of two groups respectively were 95.2％ vs 93.3％,78.9％ vs 75.0％,67.6％ vs 64.9％ (P=0.475),and 5-year technique survival was 78.7％ vs 76.7％ (P=0.623),demonstrating no obvious difference.Cox regression analysis showed that age and serum albumin were risk factors for the survival of patients.Conclusions The effect and prognosis of peritoneal dialysis in patients with polyeystic kidney and non polyeystic kidney were similar.Peritoneal dialysis is not the contraindication of polycystic kidney.Peritoneal dialysis can be used as a routine renal replacement therapy in patients with polycystic kidney disease.
RESUMEN
Objective To study the effect of different dialysis modalities on pruritus in elderly maintenance hemodialysis patients.Methods Totally 51 patients were randomly divided into hemoperfusion combined with hemodialysis group (HD+ HP),hemodiafiltration group (HDF) and hemodialysis group (HD).Plasma β2-microglobulin(β2-MG) and intact parathyroid hormone (iPTH) were measured by means of radio immunoassay at pre and post dialysis,4 weeks and 8 weeks after dialysis,cutaneous pruritus was scored.The remission rate of itching was calculated at 8 weeks after dialysis.The parameters were compared among different groups.Results The level of plasma β2-MG was lower in HD+HP group after dialysis than pre dialysis [(13.48±3.05)mg/L vs.(16.27±4.73) mg/L,t＝2.044,P＜0.05],at 4 weeks and 8 weeks after dialysis,its levels were decreased to (10.97±3.25)mg/L(t＝3.808,P＝0.002)and (6.47±2.35)mg/L(t＝7.650,P＝0.000),respectively.The levels of iPTH were also found decrease from(887.5 ± 242.7)ng/L to (688.3 ±223.4)ng/L(t＝3.384,P＝0.004)at 4 weeks and (467.2±102.5) ng/L(t＝6.578,P＝0.000) at 8weeks after dialysis in HD+HP group (all P＜0.01).There were differences of the levels of plasma β2-MG and iPTH at 4 weeks and 8 weeks after dialysis in HDF group (all P＜ 0.05),but no differences of the levels of plasma β2-MG and iPTH during every period were found in HD group(all P＞0.05).The scores of cutaneous pruritus were decreased from (21.17± 5.01) scores to (13.37±2.85) scores(t＝ 5.580,P＝0.000)at 4 weeks and (8.52±4.38) scores(t＝7.838,P＝0.000)at 8 weeks after dialysis in HD+ HP group,and also the scores at 4 and 8 weeks after dialysis in HDF group (all P＜0.01),but there were no significant differences of the scores during every period in HD group (all P＞0.05).The remission rate of itching was better in HD+ HP group than in HDF group [88.24％ (15/17 cases) vs.58.82％ (10/17 cases),x2＝14.44,P＝0.000],better in HDF group than in HD group 23.53％ (4/17 cases) (x2 ＝4.37,P＝0.037).Conclusions HD+HP is superior to HDF in efficiently clear β2-MG and iPTH,and relief cutaneous pruritus,but HD can poorly clear β2-MG and iPTH or relief itching.
