BACKGROUND: Digoxin, a cardiac glycoside used for the treatment of heart failure, was reported to inhibit the retinoid-related orphan receptor gamma t (RORγt) and attenuate the severity of experimental autoimmune encephalomyelitis and arthritis in mice. However, the effects of digoxin in a mice model of inflammatory bowel disease have not been elucidated. METHODS: Colitis was induced in severe combined immunodeficiency mice by adoptive transfer of CD45RB CD4 T cells...

Sudden cardiac death (SCD) is the most devastating manifestation of ventricular arrhythmias (VAs), and is the leading cause of mortality among atrial fibrillation (AF) patients. The goal of the present study was to investigate the incidence of SCD/VAs amongst patients with and without AF. We also aimed to identify important risk factors of SCD/VAs among AF patients. Using the "National Health Insurance Research Database" in Taiwan, a total of 352,656 AF and 352,656 non-AF patients without antecedent SCD/VAs were identified...

INTRODUCTION: Digoxin is commonly prescribed to elderly patients with heart failure and atrial fibrillation, and macrolide antibiotics markedly increase the risk of digoxin toxicity. OBJECTIVE: The aim was to determine whether, in older patients receiving digoxin, macrolide antibiotics are associated with sudden death. METHODS: We used a population-based, nested, case-control design from January 1, 1994 to December 31, 2012 in a cohort of Ontario residents aged 66 years or older prescribed digoxin...

Sacubitril/valsartan (LCZ696) is indicated for the treatment of heart failure with reduced ejection fraction. Absorption of sacubitril/valsartan and conversion of sacubitril (prodrug) to sacubitrilat (neprilysin inhibitor) was rapid with maximum plasma concentrations of sacubitril, sacubitrilat, and valsartan (angiotensin receptor blocker) reaching within 0.5, 1.5-2.0, and 2.0-3.0 h, respectively. With a two-fold increase in dose, an increase in the area under the plasma concentration-time curve was proportional for sacubitril, ~1...

INTRODUCTION: Cor triatriatum is a congenital cardiac anomaly in which the left (sinister) or right (dexter) atrium is divided into two compartments by residual embryonic tissue, resulting in a tri-atrial heart. As cor triatriatum dextrum can present clinically in various ways and have multiple associated cardiac anomalies, this report attempts to contribute to what is known about this exceedingly rare disorder. CASE: A 40 year old Hispanic man with a medical history of gastritis presented with complaints of palpitations, dizziness and bilateral lower extremity edema...

We performed a comprehensive review of the scientific literature on the use of digoxin in heart failure and atrial fibrillation. In congestive heart failure (CHF) there is only one randomized trial with a statistical sample sufficiently large. In this trial (DIG trial), which enrolled patients with systolic left ventricular dysfunction in sinus rhythm, digoxin had a neutral action on mortality and modestly reduced the overall need of hospitalization. The study was conducted in the pre-beta-blocker era and, therefore, it has a doubtful application to the current clinical context...

Recent studies have revealed that cardiac glycosides, such as digitalis and digoxin, have anticancer activity and may serve as lead compounds for the development of cancer treatments. The poor prognosis of hepatocellular carcinoma (HCC) patients reflects the development of resistance to current chemotherapeutic agents, highlighting the need for discovering new small-molecule therapeutics. Here, we found that lanatoside C, an anti-arrhythmic agent extracted from Digitalis lanata, inhibited the growth of HCC cells and dramatically decreased tumor volume as well as delayed tumor growth without obvious body weight loss...

BACKGROUND: Atrial fibrillation is the most common arrhythmia of the heart with a prevalence of approximately 2% in the western world. Atrial flutter, another arrhythmia, occurs less often with an incidence of approximately 200,000 new patients per year in the USA. Patients with atrial fibrillation and atrial flutter have an increased risk of death and morbidities. In the management of atrial fibrillation and atrial flutter, it is often necessary to use medical interventions to lower the heart rate...

The OECD GD 129 BALB/c 3T3 Neutral Red Uptake (NRU) assay is a standardized test method for estimating starting dose for an acute oral systemic toxicity test in rodents. Mouse BALB/c 3T3 fibroblasts are the most commonly used cells in the NRU assay. We have previously transferred and validated BALB/c 3T3 NRU assay in our GLP laboratory. Subsequently, in order to obtain more human relevant cytotoxicity data, we performed an intra-laboratory validation using human BJ fibroblasts in the NRU assay instead of mouse BALB/c 3T3 fibroblasts...

In heart failure (HF), the heart cannot pump blood efficiently and is therefore unable to meet the body's demands of oxygen, and/or there is increased end diastolic pressure. Current treatments for heart failure with reduced ejection fraction (HFrEF) include angiotensin-converting enzyme (ACE)-inhibitors, angiotension receptor type 1 (AT1 ) antagonists, β-adrenoceptor-antagonists, aldosterone receptor antagonists, diuretics, digoxin and a combination drug with AT1 receptor antagonist and neprilysin inhibitor...

Conflicting data exist for the appropriate management of a neonate with supraventricular tachycardia (SVT). We sought to assess postnatal prescribing trends for neonates with SVT and to evaluate if there were therapy-specific mortality and resource utilization benefits. Nationally distributed data from 44 pediatric hospitals in the 2004 to 2015 Pediatric Health Information System database were used to identify patients admitted at ≤2 days of age with structurally normal hearts and treated with an antiarrhythmic medication...

Aims: Transcatheter aortic valve implantation (TAVI) is frequently associated with cardiac conduction defects (CCD) requiring permanent pacemaker implantation (PPI). Although new-onset left bundle branch block (LBBB) is often seen, the rate of progression to severe CCD is unclear. We aimed to find clinical and electrocardiographic (ECG) parameters associated with severe CCD requiring PPI in patients with a new-onset LBBB after TAVI and assess its effect on clinical outcome. Methods and results: All consecutive patients undergoing TAVI who developed a new-onset LBBB were retrospectively analysed...

Na,K-ATPases are energy consuming ion pumps that are required for maintaining ion homeostasis in most cells. In the retina, Na,K-ATPases are especially important to sustain the dark current in photoreceptor cells needed for rapid hyperpolarization of rods and cones in light. Cardiac glycosides like digoxin inhibit the activity of Na,K-ATPases by targeting their catalytic alpha subunits. This leads to a disturbed ion balance, which can affect cellular function and survival. Here we show that the treatment of wild-type mice with digoxin leads to severe retinal degeneration and loss of vision...
