PURPOSE: Thiamine is an essential component of glucose metabolism and energy production. The disulfide derivative, thiamine tetrahydrofurfuryl disulfide (TTFD), is better absorbed than readily-available water-soluble thiamine salts because it does not require the rate-limiting transport system required for thiamine absorption. However, the detailed pharmacokinetics of thiamine and TTFD under normal and pathological conditions have not yet been clarified. C-11-labeled thiamine and TTFD were recently synthesized by our group...

PURPOSE: Observational studies indicate a positive association between circulating 25-hydroxyvitamin D (25OHD) and testosterone (T) concentrations. Because low 25OHD concentrations and T deficiency are considered to be a generalized phenomenon in patients with advanced heart failure (HF), we aimed to investigate whether vitamin D supplementation has beneficial effects on T indices in these patients. METHODS: In a pre-specified secondary analysis of the EVITA (effect of vitamin D on mortality in heart failure) randomized controlled trial, we analyzed in male subjects with 25OHD concentrations < 75 nmol/L the effect of a daily vitamin D3 supplement of 4000 IU for 3 years (n = 71) vs...

OBJECTIVE: Iron deficiency (ID) is the most common nutritional deficiency, and iron metabolism becomes further deteriorated in the presence of certain conditions, such as heart failure (HF). Atrial fibrillation (AF) has many similarities to HF, including a chronic inflammatory pathophysiology; however, the prevalence of ID and other hematinic deficiencies in AF patients have not been determined. METHODS: In this study, the prevalence of iron (serum ferritin <100 µg/L or ferritin 100-299 µg/L with transferrin saturation <20%), vitamin B12 (<200 pg/mL), and folate deficiency (<4...

This research is designed to test the hypothesis that elevated homocysteine (Hcy) levels in vivo, caused by a deficit in vitamin B complex, promote changes in cardiac function and redox status that lead to heart failure. In order to conduct the study, we used adult male Wistar albino rats (n=30; 4 weeks old; 100±15 g body weight). Hyperhomocysteinemia (HHcy) in these animals was achieved by dietary manipulation. For 4 weeks, the animals were fed with a standard rodent chow (control - CF), a diet enriched in methionine with no deficiency in B vitamins (i...

Vitamin supplementation in disease reduces morbidity and mortality in humans by promoting the activation of different genes which influence several pathways. The purpose of this article is to clarify the role of vitamin E in mast cell inflammation. Vitamin E is a fat soluble antioxidant which protects from low-density lipoprotein (LDL) oxidation. Vitamin E promotes a barrier function and anti-inflammatory responses by binding the regulatory domain of protein kinase Cα (pkcα) (a regulator and antagonist of heart failure) and decreases the activation of NF-қb, a proinflammatory transcription factor, causing the generation of cytokines/chemokines and mast cell activation...

Low vitamin D status is common in patients with heart failure and may influence bone health. A daily vitamin D dose of 4000 IU (moderately high dose) for 3 years had however no effect on parameters of bone metabolism, even in patients with very low vitamin D status. INTRODUCTION: Low vitamin D status is common in patients with heart failure (HF) and has been related to disturbed bone turnover. The present study investigated the effect of a daily vitamin D3 dose of 4000 IU on bone turnover markers (BTMs) in patients with advanced HF and 25-hydroxyvitamin D (25OHD) concentrations < 75 nmol/L...

BACKGROUND: Vitamin D deficiency has been associated with a poor outcome in patients with heart failure (HF). We examined the role of vitamin D in the response of HF patients to cardiac resynchronization therapy (CRT). METHODS: The study comprised 50 patients (30 men and 20 women) with HF undergoing CRT implantation who were prospectively enrolled. Response to CRT was defined as a combination of ≥15% reduction in left ventricular end-systolic volume (LVESV) and ≥10% improvement in the 6‑Minute Walk Test within 6 months...

AIM: The aim of this review was to summarize evidence on the role of Vitamin D deficiency in heart failure (HF), from pathophysiological mechanisms to clinical effects of Vitamin D supplementation. DATA SYNTHESIS: Chronic HF secondary to left ventricular (LV) systolic dysfunction is a growing health problem, still associated with poor clinical outcome. In recent years, experimental and epidemiological evidence focused on the role of Vitamin D in HF. Cross sectional studies demonstrated that prevalence of HF is increased in patients with Vitamin D deficiency or parathyroid hormone (PTH) plasma level increase, whereas longitudinal studies showed enhanced risk of developing new HF in patients with Vitamin D deficiency...

BACKGROUND: Low 25-hydroxyvitamin D (25OHD) levels (< 75 nmol/l) are inversely associated with anemia prevalence. Since anemia and low 25OHD levels are common in patients with heart failure (HF), we aimed to investigate whether vitamin D supplementation can reduce anemia prevalence in advanced HF. METHODS: EVITA (Effect of Vitamin D on Mortality in Heart Failure) is a randomized, placebo-controlled clinical trial in patients with initial 25OHD levels < 75 nmol/l...

BACKGROUND: Pulmonary hypertension (PH), caused by elevated pulmonary vascular resistance, leads to right heart failure and ultimately death. Vitamin D deficiency can predispose individuals to hypertension and left ventricular dysfunction; however, it remains unknown how serum vitamin D level is related to PH and right ventricular (RV) dysfunction. METHODS: Serum 25-hydroxyvitamin D [25(OH)D] levels were assessed in PH patients for an association with disease severity...

Aims: Circulating 25-hydroxyvitamin D (25OHD) levels <75 nmol/L are associated with a nonlinear increase in mortality risk. Such 25OHD levels are common in heart failure (HF). We therefore examined whether oral vitamin D supplementation reduces mortality in patients with advanced HF. Methods and results: Four hundred HF patients with 25OHD levels <75 nmol/L were randomized to receive 4000 IU vitamin D daily or matching placebo for 3 years. Primary endpoint was all-cause mortality...

BACKGROUND/INTRODUCTION: Recent studies have indicated a much broader role to Vitamin D than simply the regulation of calcium metabolism alone. Vitamin D likely confers physiologically relevant pleiotropic functions that include cardioprotective and immunomodulatory effect, and its deficiency could lead to increased risk of cardiovascular disease and heart failure. AIM: The aim of our work was to evaluate the presence of hypovitaminosis D in patients with dilated cardiomyopathy (DCMP) and to study any correlation of echocardiographic parameters with Vitamin D deficiency...

Background.: Uraemic cardiomyopathy, a process mainly associated with increased myocardial fibrosis, is the leading cause of death in chronic kidney disease patients and can be prevented by vitamin D receptor activators (VDRAs). Since some microRNAs (miRNAs) have emerged as regulators of the fibrotic process, we aimed to analyse the role of specific miRNAs in VDRA prevention of myocardial fibrosis as well as their potential use as biomarkers. Methods.: Wistar rats were nephrectomized and treated intraperitoneally with equivalent doses of two VDRAs: calcitriol and paricalcitol...
