BACKGROUND: Gastrointestinal cancers are characterized by a male predominance, suggesting a role of sex hormones.We hypothesized that digitalis medication, due to its estrogenic properties, decreases the risk of male-predominated gastrointestinal cancers. RESULTS: Long -term digitalis use (≥2 years) was followed by decreased risk for several gastrointestinal cancers, but associations were statistically significant only for liver cancer (hazard ratio [HR]=0.40, 95% confidence interval (CI) 0...

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...

Digitonin, a steroidal saponin obtained from the foxglove plant (Digitalis purpurea), displays a wide spectrum of biological properties and is often used as a model in mechanistic investigations of the biological activity of saponins. In the present study, Langmuir monolayers of zwitterionic (DPPC, DMPE, POPC, POPE, DSPC, DSPE, and DPPE) and ionic (DPPS and DPPG) phospholipids were employed in order to better understand the effect of digitonin on the lipid organization. For this purpose, a combination of surface pressure relaxation, infrared reflection absorption spectroscopy (IRRAS), and fluorescence microscopy measurements was used...

A 58 years healthy old woman was admitted to the Emergency Department (ED) with cardiac arrest due to ventricular fibrillation (VF). Appropriate cardiopulmonary resuscitation (CPR), multiple DC shocks and oro-tracheal intubation (OTI) were effective to induce recovery of spontaneous circulation (ROSC). After ROSC was achieved, the electrocardiogram (ECG) showed an idio-ventricular rhythm with atrioventricular dissociation. A transcutaneous pacing was hence applied and the patient was administered with isoproterenol...

A systematic review was conducted for all published case reports on drug-induced torsade de pointes (TdP) in elderly (≥80 years) patients to study if the administration of the offending agent was reckless. Overall, 61 reports on drug-induced TdP in patients aged 80-97 years were included in the analysis. Non-modifiable risk factors for drug-induced TdP (e.g. acute coronary syndrome, female gender and congestive heart failure), modifiable risk factors (e.g. hypokalemia, severe hypomagnesemia and digitalis toxicity) and reckless administration of a QT interval-prolonging agent (e...

Up to 20%-30% of patients with metastatic non-medullary thyroid cancer have persistent or recurrent disease resulting from tumor dedifferentiation. Tumor redifferentiation to restore sensitivity to radioactive iodide (RAI) therapy is considered a promising strategy to overcome RAI resistance. Autophagy has emerged as an important mechanism in cancer dedifferentiation. Here, we demonstrate the therapeutic potential of autophagy activators for redifferentiation of thyroid cancer cell lines. Five autophagy-activating compounds, all known as digitalis-like compounds, restored hNIS expression and iodide uptake in thyroid cancer cell lines...

BACKGROUND In 2011, following a period with delivery problems, the only registered digitoxin drug in Norway was replaced with digoxin. As a result, approximately 21 000 patients had to replace digitoxin with digoxin. There are important pharmacokinetic differences between digitoxin and digoxin (the general term for both drugs is digitalis), which must be taken into account when changing therapy. The aim of this study was to investigate compliance of drug security, during the transition from digitoxin to digoxin in Norway...

Bupivacaine toxicity following accidental overdose still lacks therapeutic solution. However, there are major arguments for testing BPC 157 against bupivacaine toxicity in vivo in rats, in particular, and then finally, in vitro. These are: the lack of any known BPC 157 toxicity, a lifesaving effect via the mitigation of arrhythmias in rats underwent hyperkalemia or digitalis toxicity, the elimination of hyperkalemia and arrhythmias in rats underwent succinylcholine toxicity and finally, the reduction of potassium-induced depolarization in vitro (in HEK293 cells) in severe hyperkalemia...

Cardiac glycosides, the cardiotonic steroids such as digitalis have been in use as heart ailment remedy since ages. They manipulate the renin-angiotensin axis to improve cardiac output. However; their safety and efficacy have come under scrutiny in recent times, as poisoning and accidental mortalities have been observed. In order to better understand and exploit them as cardiac ionotropes, studies are being pursued using different cardiac glycosides such as digitoxin, digoxin, ouabain, oleandrin etc. Several cardiac glycosides as peruvoside have shown promise in cancer control, especially ovary cancer and leukemia...

"Digitalis toxicity, often candidly indexed as poisoning, has plagued the medical profession for over 200 years. The situation qualifies as a professional disgrace on the basis of three items: the situation persists, physicians are often slow to recognize it and, over the decades, writers have been harsh in their denunciation of fellow physicians when toxicity has occurred…." These are the opening remarks of an essay published in 1983 on the 2nd centenary of William Withering's 'magic potion from foxglove's extract for dropsy...

Endogenous digitalis-like factors were found in the mammalian and human blood. It was the starting point for the elucidation of the new non-pumping function of the Na(+),K(+)-ATPase. It was previously well known that Na(+),K(+)-ATPase is a pharmacological target receptor for cardiac glycosides (J.C. Skou. 1957. Biochim. Biophys. Acta, 23: 394-401). We have investigated the trophotropic effects of such agents as ouabain, epinephrine, norepinephrine, atenolol, and comenic acid using the organotypic tissue culture combined with the reconstruction of optical cross sections and confocal microscopy...

BACKGROUND: In the PARADIGM-HF trial (Prospective Comparison of ARNI with ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure), the angiotensin receptor neprilysin inhibitor sacubitril/valsartan was more effective than the angiotensin-converting enzyme inhibitorenalapril in patients with heart failure and reduced ejection fraction. We examined whether this benefit was consistent irrespective of background therapy. METHODS AND RESULTS: We examined the effect of study treatment in the following subgroups: diuretics (yes/no), digitalis glycoside (yes/no), mineralocorticoid receptor antagonist (yes/no),and defibrillating device (implanted defibrillating device, yes/no)...
