Efficacy, safety and tolerability of combined low-dose simvastatin-fenofibrate treatment in primary mixed hyperlipidaemia.

2007

In order to assess the long-term (12 months) efficacy and safety of fenofibrate administered with simvastatin in the treatment of primary mixed hyperlipidaemia, we conducted a study that compared increasing dosages of these drugs in subgroups of men and women belonging to a clinical sample of outpatients. This was an open study carried out in patients with primary mixed hyperlipidaemia (lipoprotein phenotype IIb) who needed a combined therapeutic approach because of their poor response to a single-drug regimen with an HMG-CoA reductase inhibitor (simvastatin). Thus, a fibrate (fenofibrate) was added to the therapy. The study lasted 12 months. Forty-five patients (mean age: 58.9 ± 11.3 years…

Fibratos: efectos farmacológicos

2012

Fibrates have demonstrated efficacy in modifying the various parameters of atherogenic dyslipidemia. The best known fibrate is fenofibrate, which is indicated for the treatment of hypertriglyceridemia with or without low high-density lipoprotein cholesterol (HDL-c) and the treatment of atherogenic dyslipidemia in patients with statin intolerance or contraindications. Fenofibrate is also indicated in association with statins in patients with high cardiovascular risk when HDL-c and triglyceride (TG) concentrations are poorly controlled. The lipid-lowering effects of fenofibrate are mediated by activation of the nuclear transcription factor PPARα, which leads to an increase of lipolysis and pl…

Phenotype characterization of the anti-inflammatory behavior of decidual endothelial cells

2008

Problem:  During pregnancy, an adequate inflammatory control is essential for normal intrauterine foetus development. Vascular endothelium is known to play a critical role in regulation of inflammatory processes. We hypothesize a different ability of decidual endothelial cells (DEC) compared to endothelium from other districts to respond to inflammatory stimuli. Material and Methods:  DEC were isolated and activated with inflammatory stimuli and their response in term of adhesion molecules expression, vascular leakage and cytokines production was evaluated. These data were compared to the data obtained with HUVEC and microvascular endothelial cells isolated from human skin (ADMEC) and from …

Clinical Role of CA125 in Worsening Heart Failure

2020

Abstract Objectives The aim of this study was to evaluate the association between antigen carbohydrate 125 (CA125) and the risk of 1-year clinical outcomes in patients with worsening heart failure (HF). Background CA125 is a widely available biomarker that is up-regulated in patients with acute HF and has been postulated as a useful marker of congestion and risk stratification. Methods In a large multicenter cohort of patients with worsening HF, either in-hospital or in the outpatient setting, the independent associations between CA125 and 1-year death and the composite of death/HF readmission (adjusted for outcome-specific prognostic risk score [BIOSTAT risk score]) were determined by usin…

Cluster headache in relation to different age groups

2019

Cluster headache (CH) has always been considered a type of primary headache affecting predominantly male subjects in early and medium adulthood. However, recent studies carried out in large case series of patients with CH show that not infrequently it may set in also after age 50; by contrast, onset before adolescence is very rare. Additionally, when onset occurs before age 14 or from the sixth decade of life onward, male predominance decreases to the point that in chronic forms CH predominantly affects the female sex. This particular pattern of the gender ratio in relation to onset in different age groups suggests that hormonal factors may actually play a role in the genesis of CH. In part…

Diacylglycerol kinase α mediatses 17-β-estradiol-induced proliferation, motility, and anchorage-independent growth of Hec-1A endometrial cancer cell …

2011

Increased levels of endogenous and/or exogenous estrogens are one of the well known risk factors of endometrial cancer. Diacylglycerol kinases (DGKs) are a family of enzymes which phosphorylate diacylglycerol (DAG) to produce phosphatidic acid (PA), thus turning off and on DAG-mediated and PA-mediated signaling pathways, respectively. DGK α activity is stimulated by growth factors and oncogenes and is required for chemotactic, proliferative, and angiogenic signaling in vitro. Herein, using either specific siRNAs or the pharmacological inhibitor R59949, we demonstrate that DGK α activity is required for 17-β-estradiol (E2)-induced proliferation, motility, and anchorage-independent growth of …

Statin-Induced Liver Injury Involves Cross-Talk between Cholesterol and Selenoprotein Biosynthetic Pathways

2009

Statins have become the mainstay of hypercholesterolemia treatment. Despite a seemingly clear rationale behind their use, the inhibition of HMG-CoA reductase, these compounds have been shown to elicit a variety of unanticipated and elusive effects and side effects in vivo. Among the most frequently noted side effects of statin treatment are elevations in liver enzymes. Here, we report our finding that atorvastatin, cerivastatin, and lovastatin at clinically common concentrations induce a selective, differential loss of selenoprotein expression in cultured human HepG2 hepatocytes. The primarily affected selenoprotein was glutathione peroxidase (GPx), whose biosynthesis, steady-state expressi…

Local Treatment of Urogenital Atrophy with an Estradiol-Releasing Vaginal Ring: A Comparative and a Placebo-Controlled Multicenter Study

1999

Local estrogen substitution has been shown to be more appropriate than any systemic application for the treatment of urogenital symptoms of hormone defiency. The efficacy, safety and acceptability of a new low-dose drug delivery system consisting of an estradiol-releasing silicone vaginal ring was studied in two multicenter trials. In an open-label comparative trial a total of 219 postmenopausal women were randomized to the estradiol-releasing vaginal ring or to estriol suppositories. In terms of efficacy both treatment arms were shown to be equivalent; however, significantly higher rates of acceptability were found for the vaginal ring. In a double-blinded placebo-controlled study a total …

Alimentary and Pharmaceutical Approach to Natural Antimicrobials against Clostridioides difficile Gastrointestinal Infection

2021

Incidence of Clostridioides difficile infection (CDI) has been increasing in recent decades due to different factors, namely (i) extended use of broad-spectrum antibiotics, (ii) transmission within asymptomatic and susceptible patients, and (iii) unbalanced gastrointestinal microbiome and collateral diseases that favor C. difficile gastrointestinal domination and toxin production. Although antibiotic therapies have resulted in successful control of CDI in the last 20 years, the development of novel strategies is urged in order to combat the capability of C. difficile to generate and acquire resistance to conventional treatments and its consequent proliferation. In this regard, vegetable and…
