CD62P and P10 as predictive markers for assessing the efficacy of hemodialysis in treating end-stage renal disease.

ABSTRACT: BACKGROUND:CD62P is a platelet ?-granule membrane protein, and P10 is a platelet membrane glycoprotein thrombospondin. To better understand the effects of hemodialysis (HD), we have conducted this study to investigate CD62P and P10 in assessing the efficacy of HD in treating patients with end-stage renal disease (ESRD). METHODS:The case group consisted of 111 patients suffering ESRD treated with regular HD and the control group enrolled 117 healthy subjects. Before and after HD treatment, a series of parameters were observed, based on which, CD62P and P10 levels were detected in the patients in two groups before and after HD therapy. The correlation analysis analyzed the correlations of CD62P and P10 markers with serum creatinine (Scr), blood urea nitrogen (BUN), and subjective score; and logistic regression analysis was performed to reveal factors affecting the efficacy of HD. RESULTS:BUN, Scr, serum phosphorus, intact parathyroid hormone (iPTH), fibrinogen, and ?2-microglobulin (?2-MG) decreased while hemoglobin, albumin, and activated partial thromboplastin time increased in the patients suffering ESRD; patients presented with improvements in subjective symptoms and an increase in dry weight. CD62P and P10 levels were lower in post-treatment patients. CD62P and P10 positively correlated with Scr, BUN and subjective score; post-treatment CD62P and P10 levels, BUN, hemoglobin, albumin, triglyceride, iPTH, ?2-MG, and fibrinogen were correlated with the efficacy of HD. CONCLUSION:CD62P and P10 might be correlated to the efficacy of HD in treating ESRD, in turn providing predictive markers for assessing the ability of HD in treating ESRD.

Project description:BackgroundPatients with end-stage renal disease on hemodialysis (ESRD-HD) and aortic stenosis have poor prognosis. The role of transcatheter aortic valve replacement (TAVR) in this high-risk population is debated.MethodsWe compared the outcomes among ESRD-HD Medicare beneficiaries who were managed with TAVR, surgical AVR (SAVR), or conservative management for aortic stenosis between 2015 and 2017, using overlap propensity score weighting analysis to control for differences in treatment assignment. The primary outcome was all-cause mortality and was compared between treatment groups as well as to age-sex matched mortality for ESRD-HD in the US population. Secondary outcomes included trend of heart failure hospitalizations.ResultsA total of 8107 ESRD-HD patients with aortic stenosis were included, 4130 (50%) underwent TAVR, 2565 (31.6%) underwent SAVR, and 1412 (17.4%) were managed conservatively. TAVR patients had more comorbidities and higher frailty compared with the other 2 groups. Thirty-day mortality was lower with TAVR compared with SAVR (4.6% versus 12.8%, P<0.01). After a median follow-up of 465 days (interquartile range, 261-759), on overlap propensity score weighting analysis, there was no difference in mortality between TAVR and SAVR (adjusted hazard ratio, 1.02 [95% CI, 0.91-1.15], P=0.7), and mortality was lower with TAVR compared with conservative management (adjusted hazard ratio, 0.53 [95% CI, 0.47-0.60], P<0.001). Standardized mortality ratios with TAVR, SAVR, and conservative management compared with age-sex matched ESRD-HD US population were 1.24, 1.27, and 1.83, respectively. The rate of heart failure admissions declined after TAVR (incidence rate ratio, 0.55 [95% CI, 0.48-0.62], P<0.001) and SAVR (incidence rate ratio, 0.76 [95% CI, 0.65-0.88], P<0.001).ConclusionsIn ESRD-HD patients with aortic stenosis, mortality was lower in the short-term with TAVR compared with SAVR but comparable in the mid-term. AVR is associated with an improvement in survival and reduction in heart failure hospitalizations compared with conservative management.

Project description:BACKGROUND:Poor nutritional status is frequently observed in end-stage renal disease patients and associated with adverse clinical outcomes and increased mortality. Loss of amino acids (AAs) during hemodialysis (HD) may contribute to protein malnutrition in these patients. OBJECTIVE:We aimed to assess the extent of AA loss during HD in end-stage renal disease patients consuming their habitual diet. METHODS:Ten anuric chronic HD patients (mean ± SD age: 67.9 ± 19.3 y, BMI: 23.2 ± 3.5 kg/m2), undergoing HD 3 times per week, were selected to participate in this study. Spent dialysate was collected continuously and plasma samples were obtained directly before and after a single HD session in each participant. AA profiles in spent dialysate and in pre-HD and post-HD plasma were measured through ultra-performance liquid chromatography to determine AA concentrations and, as such, net loss of AAs. In addition, dietary intake before and throughout HD was assessed using a 24-h food recall questionnaire during HD. Paired-sample t tests were conducted to compare pre-HD and post-HD plasma AA concentrations. RESULTS:During an HD session, 11.95 ± 0.69 g AAs were lost via the dialysate, of which 8.26 ± 0.46 g were nonessential AAs, 3.69 ± 0.31 g were essential AAs, and 1.64 ± 0.17 g were branched-chain AAs. As a consequence, plasma total and essential AA concentrations declined significantly from 2.88 ± 0.15 and 0.80 ± 0.05 mmol/L to 2.27 ± 0.11 and 0.66 ± 0.05 mmol/L, respectively (P < 0.05). AA profiles of pre-HD plasma and spent dialysate were similar. Moreover, AA concentrations in pre-HD plasma and spent dialysate were strongly correlated (Spearman's ? = 0.92, P < 0.001). CONCLUSIONS:During a single HD session, ?12 g AAs are lost into the dialysate, causing a significant decline in plasma AA concentrations. AA loss during HD can contribute substantially to protein malnutrition in end-stage renal disease patients. This study was registered at the Netherlands Trial Registry (NTR7101).
