Association Between Risk Factors Including Bone-Derived Biomarkers and Aortic Arch Calcification in Maintenance Hemodialysis Patients

Abstract Background Elderly Hemodialysis patients are increasing yearly. Antihypertensive medications are commonly prescribed to hemodialysis patients but the optimal regimens to prevent morbidity andmortality are unknown. The goal of our study was to compare the association of routinely prescribed antihypertensive regimens with outcomes and analyze the risk factors in elderly hemodialysis patients.Methods This study was a retrospective cohort study based on data from adult hemodialysis patients (≥18 years old) admitted to 15 hospitals in China between 1 January 2009 and 31 December 2011. The characteristics of elderly hemodialysis patients (≥60 years old) were analyzed. Antihypertensive drugs into the following regimens: β-blockers, calcium channel blockers, renin–angiotensin system (RAS) blocking drugs and α-blockers. Logistic regression analysis was used to explore the risk factors for death adjusting for clinical and laboratory values and antihypertensive medications.Results A total of 7135 patients on maintenance hemodialysis including 2738 elderly patients were enrolled in this study. The mean levels of hemoglobin, albumin, blood calcium, phosphorus and parathyroid hormone (PTH) in elderly group were lower than the younger group. We compared the characteristics of 2492 survived elderly maintenance hemodialysis patients and 246 patients who died.Aging (OR = 1.59, 95% CI: 1.13-2.24), central venous catheter (OR = 1.62, 95% CI: 1.53-1.72) and Charlson comorbidities index>3(OR=1.97,95% CI: 1.49-2.60)were independently risk factors of mortality in elderly maintenance hemodialysis patients. High levels of hemoglobin (OR=0.76, 95%CI: 0.73-0.79), albumin (OR=0.87, 95%CI: 0.77-0.98), uric acid(OR=0.90,95%CI: 0.84-0.96)and those taking angiotensin-converting enzyme inhibitor (ACEI) or an angiotensin II receptor blocker (ARB) (OR=0.77, 95%CI: 0.58-0.90) had a lower risk of mortality.Conclusions Age, Charlson Comorbidities index >3, anemia and malnutrition, the use of central venous catheters and low serum uric acid level are risk factors for mortality in elderly maintenance hemodialysis patients. Taking ACEI/ARB can reduce the mortality of elderly maintenance hemodialysis patients.

Maintenance Hemodialysis Patients

Background and AimTricuspid regurgitation (TR) is a frequent complication in various cardiovascular diseases. However, few studies have reported the prevalence of TR especially the moderate to severe or significant TR (ms-TR) maintenance dialysis patients. Thus, we aimed to identify the prevalence of ms-TR and its associated factors.MethodsA total of 491 maintenance dialysis patients underwent echocardiographic examinations, while a subgroup (n = 283) also received routine blood tests, renal function examinations, and electrolyte analysis. We first compared the differences in abovementioned parameters among groups with various TR areas (TRAs). Finally, univariate and adjusted regression were also used to identify factors that were independently associated with ms-TR.ResultsThe incidence of TR jets was 62.6%, which included a mildly increased TRA (47.8%), moderately increased TRA (10.4%), and severely increased TRA (3.5%). Most of the cardiac structures and functional parameters, such as the end-diastolic internal diameters of the left atrium (LA), left ventricle (LVDD), right atrium (RA), right ventricle (RV), left ventricular ejection fraction (LVEF), and fractional shortening (FS), were significantly associated with ms-TR. Among serum ions, only total CO2 (TCO2; r = −0.141, p = 0.047) was negatively correlated with TRA. After adjusted, only Na+ [odds ratio (OR): 0.871 0.888, p = 0.048], RA (OR: 1.370, p < 0.001), and FS (OR: 0.887, p < 0.001) were independently associated with ms-TR.ConclusionTricuspid regurgitation occurs in maintenance hemodialysis patients with ESRD. Na+ FS and RA were independently associated with ms-TR, and these parameters may be potential risk factors/predictors for ms-TR.
