Superior prognostic value of soluble suppression of tumorigenicity 2 for the short-term mortality of maintenance hemodialysis patients compared with NT-proBNP: a prospective cohort study.

ABSTRACT: Background: Both soluble suppression of tumorigenicity 2 (sST2) and N-terminal pro-brain natriuretic peptide (NT-proBNP) are promising biomarkers associated with the adverse clinical outcomes of dialysis patients. Our research aims at exploring and comparing the roles of sST2 and NT-proBNP in predicting the short-term and long-term mortality of maintenance hemodialysis (MHD) patients.Methods: A prospective cohort study was performed. Patients undergoing hemodialysis in July 2014 were enrolled from the Blood Purification Center of Ruijin Hospital. MHD patients were followed up for 3 years. The primary outcome was all-cause mortality at the 1-year and 3-year follow-up, while the secondary outcome was cardiovascular mortality. Serum sST2 level was detected by quantified ELISA kits. Clinical data were analyzed by SPSS 23.0 version.Results: 205 patients were recruited. The median sST2 level was 15.99 (11.60, 20.49) ng/ml. After 3 years of follow-up, both all-cause and cardiovascular mortality in 1 year and all-cause and cardiovascular mortality in 3 years increased significantly with serum sST2. For short-term mortality, no significant difference was observed in patients with increasing NT-proBNP levels. Cox regression analysis indicated that only sST2 was independent in predicting the risk of short-term outcomes. For long-term mortality, both sST2 and NT-proBNP were independent risk factors, while a higher hazard ratio was observed for NT-proBNP.Conclusions: Serum sST2 is a novel biomarker associated with adverse clinical outcomes in MHD patients. It was significant for both all-cause and cardiovascular mortality in MHD patients and may provide better prognostic value in short-term prognosis than the classic biomarker NT-proBNP.

Project description:ObjectivesSoluble suppression of tumorigenicity-2 is a biomarker of myocardial strain and inflammation. The characteristics of acute respiratory distress syndrome include inflammation and cardiovascular dysfunction. We sought to determine whether plasma soluble suppression of tumorigenicity-2 concentration is associated with outcome and response to conservative fluid management and whether soluble suppression of tumorigenicity-2 concentration discriminates acute respiratory distress syndrome from decompensated heart failure.DesignA retrospective analysis of the Fluid and Catheter Treatment Trial, a multi-center randomized controlled trial of conservative fluid management in the acute respiratory distress syndrome, as well as of a cohort of patients with decompensated heart failure.SettingTwenty acute care hospitals.PatientsEight hundred twenty-six patients with acute respiratory distress syndrome and 209 patients with acutely decompensated heart failure.Measurements and main resultsNonsurvivors had higher day 0 (p < 0.0001) and day 3 (p < 0.0001) soluble suppression of tumorigenicity-2 concentrations. After adjustment for severity of illness, higher soluble suppression of tumorigenicity-2 concentration was associated with mortality, with odds ratioadj 1.47 (95% CI, 0.99-2.20; p = 0.06) at day 0, 2.94 (95% CI, 2.00-4.33; p < 0.0001) at day 3, and 3.63 (95% CI, 2.38-5.53; p < 0.0001) if soluble suppression of tumorigenicity-2 increased between days. Cumulative fluid balance was more positive among patients with higher day 0 (median, 5,212 mL [interquartile range, 200-12,284 mL] vs median, 2,020 mL [interquartile range, -2,034 to 7,091 mL]; p < 0.0001) and day 3 soluble suppression of tumorigenicity-2 (median, 7,678 mL [interquartile range, 2,217-14,278 mL] vs median, 1,492 mL [interquartile range, -2,384 to 6,239 mL]; p < 0.0001). Soluble suppression of tumorigenicity-2 showed excellent discriminative ability between the Fluid and Catheter Treatment Trial and heart failure populations (area under receiver-operating characteristic curve = 0.98; p < 0.0001).ConclusionsHigher soluble suppression of tumorigenicity-2 concentrations are associated with worse outcome in acute respiratory distress syndrome and may have value for discriminating acute respiratory distress syndrome from heart failure.

Project description:Background. Mineral metabolism (MM) system and N-terminal pro-brain natriuretic peptide (NT-ProBNP) have been shown to add prognostic value in patients with stable coronary artery disease (SCAD). However, the influence of NT-ProBNP on the prognostic role of MM in patients with SCAD has not been shown yet. The objective of this study is to assess the influence of NT-ProBNP on the prognostic role of MM markers in patients with SCAD. Methods: We analyzed the prognostic value of MM markers (parathormone (PTH), klotho, phosphate, calcidiol (25-hydroxyvitamin D3), and fibroblast growth factor-23) in 964 patients with SCAD and NT-ProBNP > 125 pg/mL vs. patient with NT-ProBNP ≤ 125 pg/mL included in five hospitals in Spain. The main outcome was the combination of death, heart failure, and ischemic events (any acute coronary syndrome, ischemic stroke, or transient ischemic attack). Results: A total of 622 patients had NT-proBNP > 125 pg/mL and 342 patients had NT-ProBNP ≤ 125 pg/mL. The median follow-up was 5.1 years. In the group of NT-proBNP > 125 pg/mL, the patients were older, and there were more females and smokers than in the group of patients with normal NT-proBNP. Additionally, the proportion of patients with hypertension, atrial fibrillation, ejection fraction < 40%, cerebrovascular attack, or prior coronary artery bypass graft was higher in the high NT-proBNP group. In the high NT-proBNP patients, the predictors of poor prognosis were PTH (HR = 1.06 (1.01–1.10), p < 0.001) and NT-proBNP (HR = 1.02 (1.01–1.03), p = 0.011), along with age (HR = 1.039 (1.02–1.06), p < 0.001), prior coronary artery bypass graft (HR = 1.624 (1.02–2.59), p = 0.041), treatment with statins (HR = 0.32 (0.19–0.53), p < 0.001), insulin (HR = 2.49 (1.59–4.09), p < 0.001), angiotensin receptor blockers (HR = 1.73 (1.16–2.56), p = 0.007), nitrates (HR = 1.65 (1.10–2.45), p = 0.014), and proton pump inhibitors (HR = 2.75 (1.74–4.36), p < 0.001). In the NT-proBNP ≤ 125 pg/mL subgroup, poor prognosis predictors were plasma levels of non-high-density lipoprotein (non-HDL) cholesterol (HR = 1.01 (1.00–1.02), p = 0.014) and calcidiol (HR = 0.96 (0.92–0.99), p = 0.045), as well as treatment with verapamil (HR = 11.28 (2.54–50.00), p = 0.001), and dihydropyridines (HR = 3.16 (1.63–6.13), p = 0.001). Conclusion: In patients with SCAD and NT-ProBNP > 125 pg/mL, PTH and NT-ProBNP, which are markers related to ventricular damage, are predictors of poor outcome. In the subgroup of patients with NT-ProBNP ≤ 125 pgm/L, calcidiol and non-HDL cholesterol, which are more related to vascular damage, are the independent predictors of poor outcome. Then, in patients with SCAD, baseline NT-ProBNP may influence the type of biomarker that is effective in risk prediction.
