Background Bile acids are important metabolites of intestinal microbiota, which have profound effects on host health. However, whether metabolism of bile acids is involved in the metabolic complications of end-stage renal disease (ESRD), and the effects of bile acids on the prognosis of ESRD remain obscure. Therefore, this study investigated the relationship between altered bile acid profile and the prognosis of ESRD patients. Methods A targeted metabolomics approach based on ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to determine the changes in serum bile acids between ESRD patients (n = 77) and healthy controls (n = 30). Univariate and multivariate statistical analyses were performed to screen the differential proportions of bile acids between the two groups. Results Six differentially expressed bile acids were identified as potential biomarkers for differentiating ESRD patients from healthy subjects. The decreased concentrations of chenodeoxycholic acid, deoxycholic acid and cholic acid were significantly associated with dyslipidemia in ESRD patients. Subgroup analyses revealed that the significantly increased concentrations of taurocholic acid, taurochenodeoxycholic acid, taurohyocholic acid and tauro α-muricholic acid were correlated to the poor prognosis of ESRD patients. Conclusions The serum bile acid profile of ESRD patients differed significantly from that of healthy controls. In addition, the altered serum bile acid profile might contribute to the poor prognosis and metabolic complications of ESRD patients.

Background: Due to the premium rate of Chronic Kidney Disease, we have increased our knowledge with respect to diagnosis and treatment of Bone Mineral Disease (BMD) in End- Stage Renal Disease (ESRD). Currently, various treatment options are available. The medication used for Secondary Hyper-Parathyroidism gives promising results in the regulation of Ca, P and Parathormone levels, improving the quality of life. The aim of the present study was to investigate the relation of cinacalcet administration to not only parathormone, Ca and P but also to anemia parameters such as hematocrit and hemoglobin. Materials and Methods: retrospective observational study was conducted in a Chronic Hemodialysis Unit. One-hundred ESRD patients were recruited for twenty-four months and were evaluated on a monthly rate. Biochemical parameters were related to medication prescribed and the prognostic value was estimated. Cinacalcet was administered to 43 out of 100 patients in a dose of 30-120 mg. Results: Significant differences were observed in PTH, Ca and P levels with respect to Cinacalcet administration. Ca levels appeared to be higher at 30mg as compared to 60mg cinacalcet. Furthermore, a decreasing age-dependent pattern was observed with respect to cinacalcet dosage. A positive correlation was observed between Dry Weight (DW) and cinacalcet dose. Finally, a positive correlation between Hematocrit and Hemoglobin and cinacalcet was manifested. Conclusions: Cinacalcet, is a potential cardiovascular and bone protective agent, which is approved for use in ESRD patients to assist SHPT. A novel information was obtained from this study, regarding the improvement of the control of anemia.

A patient with end-stage renal disease on CAPD, and with massive iron overload is reported. This patient had evidence of myocardial and hepatic damage probably as a result of iron overload. Treatment with desferoxamine resulted in removal of iron in the peritoneal dialysate. On the basis of preliminary studies in this patient it would appear that removal of iron by peritoneal dialysis in conjunction with chelation therapy is safe and effective. This finding should have wide-ranging signficance for patients with ESRD.

<b><i>Aim:</i></b> To derive an echocardiography-based prognostic score for a 3-year risk of mortality in end-stage renal disease (ESRD) patients undergoing hemodialysis (HD). <b><i>Methods:</i></b> 173 ESRD patients hospitalized in the second affiliated hospital of Soochow University from January 1, 2010, to July 31, 2016, were enrolled and followed up for 3 years. All subjects began to receive HD from recruitment. Baseline clinical and echocardiographic parameters were collected and screened for risk factors using univariate and multivariate analysis. The prognostic value of echocardiographic indexes was determined by concordance indexes and reclassification assay. Restricted cubic spline models (RCS) and forest plots were employed to visualize the association between risk factors and all-cause mortality. A multivariate nomogram including the identified factors was developed to estimate the prognosis. <b><i>Results:</i></b> After multivariate adjustment for advanced age, hypertension, diabetes, and decreased hemoglobin (Hb), echocardiographic indexes including left atrial diameter index (LADI), cardiac valvular calcification, and moderate to severe cardiac valve regurgitation were independently associated with the risk of 3-year mortality in HD patients. RCS showed that age, Hb, and LADI were positively associated with the risk of mortality. Adding multiple echocardiographic indexes to a basic model containing age, hypertension, diabetes, and Hb increased the concordance index and improved reclassification. A multivariate Cox model-derived nomogram showed the association between each factor and mortality by the end of follow-up. <b><i>Conclusions:</i></b> Echocardiographic indexes showed independent predictive power for mortality in ESRD patients and may constitute a promising prognostic tool in this population.
