Active Vitamin D Effect on Left Ventricular Hypertrophy

Chronic Kidney DiseaseSecondary Hyperparathyroidism1 more

Left ventricular hypertrophy (LVH) predicts mortality at start of dialysis. Prevention of of LVH is important. It is not known whether secondary hyperparathyroidism might induce LVH. In the present study patients are randomised to 1.25 dihydroxycholecalciferol or no treatment to study the effect on LVH.

We will directly test the hypothesis that an initial strategy of lisinopril-based therapy will be more effective than atenolol-based therapy in causing regression of left ventricular hypertrophy (LVH) over one year in patients with hemodialysis hypertension despite similar degree of BP reduction.

Anemia Correction and Fibroblast Growth Factor 23 Levels in Chronic Kidney Disease , and Renal Transplant...

Anemia of Chronic Kidney DiseaseEndothelial Dysfunction2 more

The fibroblast growth factor-23-bone-kidney axis is part of newly discovered biological systems linking bone to other organ functions through a complex endocrine network that is integrated with the parathormone/vitamin D axis and which plays an equally important role in health and disease . Most of the known physiological function of fibroblast growth factor 23 to regulate mineral metabolism can be accounted for by actions of this hormone on the kidney.In a recent experimental study, fibroblast growth factor-23 was shown to cause pathological hypertrophy in rat cardiomyocytes by "calcineurin-nuclear factor of activated T cells" and treatment with fibroblast growth factor -blockers reduced left ventricular hypertrophy in experimental models of chronic renal failure.The current hypothesis is that, in healthy individuals, iron deficiency stimulates increased production of fibroblast growth factor23. At the same time, iron is thought to be the cofactor of enzymes taking part in the degradation of intact fibroblast growth factor-23 and thought to have a role in the excretion of degraded FGF-23 parts .Studies speculated that Angiotensin Converting Enzyme inhibitors may exert their anti-proteinuria effects at least in part by reducing serum fibroblast growth factor-23 levels although it is difficult from the results of this study to understand which comes first and brings about the other; decrease in proteinuria or fibroblast growth factor-23. Available evidence points to the deleterious effects of increased fibroblast growth factor-23 level in proteinuria, but the precise molecular mechanism still remains to be explored. An intricate and close association exists among parathormone, phosphorus, active vitamin D with FGF23, but the independent role of the latter on proteinuria is the least explored. Elaborately conducted studies that control effects of confounding factors adequately are needed to demonstrate the independent pathogenic role of FGF23.

Protective Monocytes and Macrophages to Limit Decompensation and Heart Damaging

Left Ventricular Hypertrophy

The working hypothesis is that cardiac macrophages specific for the compensated cardiac hypertrophic phase limit the progression toward the decompensated state of heart failure by promoting an inflammatory environment favouring cardiomyocyte survival and preservation of the pump function. The investigators will perform studies in human plasma and monos, cardiac tissues and macrophages to validate this hypothesis.

Effect of Etelcalcetide on Cardiac Hypertrophy in Hemodialysis Patients

Secondary HyperparathyroidismChronic Kidney Disease Requiring Chronic Dialysis1 more

Background: Calcimimetic therapy has been shown to reduce systemic FGF23 levels, which themselves are associated with left ventricular hypertrophy (LVH) in chronic kidney disease (CKD). Methods/design: This is a randomized multicenter trial in which the effect of etelcalcetide in comparison to alfacalcidol on LVH and cardiac fibrosis in hemodialysis patients with secondary hyperparathyroidism (sHPT) will be investigated. The investigators will perform a comparative trial testing etelcalcetide vs. alfacalcidol treatment on top of conventional HPT therapy for 12 months. A total of 62 hemodialysis patients with sHPT and LVH will be enrolled in the study. After a washout of all calcimimetic and vitamin D treatment, subjects will be randomized at 1:1 ratio to either etelcalcetide or alfacalcidol. The participants will undergo cardiac imaging consisting of cardiac resonance imaging (cMRI) and strain echocardiography before and at baseline and one year. Etelcalcetide or alfacalcidol will be administered intravenously three times per week following chronic hemodialysis treatment. The primary end point will be a change in left ventricular mass index (LVMI) measured in g/m2. As secondary end points the changes in left atrial diameter (LAD), cardiac fibrosis, wall motion abnormalities and left ventricular function, changes in serum FGF 23 and soluble Klotho levels as well as changes in proBNP as well as pre- and postdialysis troponin T (TnT) levels will be determined. Additionally a quantitative analysis of the treatment influence on the individual metabolites of the renin-angiotensin-aldosterone system (RAAS) will be performed using mass spectrometry ("RAAS fingerprint").

Empagliflozin and Cardiac Remodelling in People Without Diabetes

Cardiovascular DiseasesLeft Ventricular Hypertrophy

The purpose of this study is to evaluate the effects of empagliflozin on cardiac structure, function and circulating biomarkers in patients with cardiovascular risk factors, but without diabetes. Empagliflozin is an antihyperglycemic agent approved by Health Canada and the FDA for the treatment of type 2 diabetes. Previous post-marketing clinical trials demonstrated a reduction in cardiovascular deaths and heart failure in patients with type 2 diabetes treated with empagliflozin. In the first EMPA-HEART trial, we demonstrated that empagliflozin reduces cardiac mass in patients with type 2 diabetes, as seen through cardiac magnetic resonance imaging (cMRI). Therefore, the aim of this study, EMPA-HEART 2, is to determine whether empagliflozin can similarly impact cardiac structure in patients without diabetes, but with various cardiovascular risk factors.
