Statin intolerance – an attempt at a unified definition. Position paper from an International Lipid Expert Panel

2015

Statins are one of the most commonly prescribed drugs in clinical practice. They are usually well tolerated and effectively prevent cardiovascular events. Most adverse effects associated with statin therapy are muscle-related. The recent statement of the European Atherosclerosis Society (EAS) has focused on statin-associated muscle symptoms (SAMS), and avoided the use of the term ‘statin intolerance’. Although muscle syndromes are the most common adverse effects observed after statin therapy, excluding other side effects might underestimate the number of patients with statin intolerance, which might be observed in 10 – 15% of patients.In clinical practice, statin intolerance limits effectiv…

Tau protein as a diagnostic and prognostic biomarker in amyotrophic lateral sclerosis

2020

BACKGROUND AND PURPOSE To test the hypothesis that total tau (tTau), tau phosphorylated at threonine 181 (pTau) and pTau/tTau ratio in the cerebrospinal fluid (CSF) are diagnostic and prognostic biomarkers of amyotrophic lateral sclerosis (ALS), we performed a retrospective observational study in a large cohort of ALS patients and controls. METHODS We enrolled 196 ALS patients and 91 controls, who included patients with ALS-mimicking diseases and those with non-neurodegenerative diseases. All patients underwent lumbar puncture for CSF analysis at the time of the diagnostic evaluation or to first referral. We measured tTau and pTau levels in the CSF by chemiluminescence enzyme immunoassay. R…

Serum sphingomyelin levels are related to the clearance of postprandial remnant-like particles.

2005

It is known that sphingomyelin (SM) content is higher in apolipoprotein B-containing particles (BLps) than in high density lipoproteins and that BLp levels, including chylomicrons and their remnant particles, are positively related to atherosclerosis. To evaluate the relationship between serum SM and postprandial remnant particle levels, we determined SM, triglyceride (TG), and cholesterol levels in serum and in remnant-like particles (RLPs) before and 3, 5, 7, and 10 h after a high-fat meal in 31 healthy subjects. We found that serum SM, like serum TG, was increased to its maximum 3 h after fat loading and then gradually decreased to basal levels after 10 h. More important, we determined t…

Differential effects of oxidized LDL on apolipoprotein AI and B synthesis in HepG2 cells

2006

Oxidized low-density lipoproteins (Ox-LDL) are key elements in atherogenesis. Apolipoprotein AI (apoAI) is an active component of the antiatherogenic high-density lipoproteins (HDL). In contrast, plasma apolipoprotein B (apoB), the main component of LDL, is highly correlated with coronary risk. Our results, obtained in HepG2 cells, show that Ox-LDL, unlike native LDL, leads to opposite effects on apoB and apoAI, namely a decrease in apoAI and an increase in apoB secretion as evaluated by [(3)H]leucine incorporation and specific immunoprecipitation. Parallel pulse-chase studies show that Ox-LDL impaired apoB degradation, whereas apoAI degradation was increased and mRNA levels were decreased.…

Learning curve for piezosurgery in well-trained otological surgeons

2009

Abstract Objective Piezosurgery is an ultrasound instrument (24.7-29.5 kHz) capable of cutting bone without necrosis and nonmineralized tissue damage. The aim of this work has been to determine the time required for a well-trained surgeon to perform otological surgery with the piezoelectric device. Study Design Case series with planned data collection. Sixty-three patients affected by otosclerosis and 63 by chronic otitis media were enrolled. For each disease, patients were divided into three numerically equal groups, with each group assigned to a well-trained otological surgeon. Patients underwent stapedotomy (n = 63) and intact canal wall tympanoplasty (n = 63) with the piezoelectric devi…

Insulin resistance aggravates atherosclerosis by reducing vascular smooth muscle cell survival and increasing CX3CL1/CX3CR1 axis.

2014

Aims Insulin resistance (IR) is a major risk factor for cardiovascular disease and atherosclerosis. Life-threatening acute events are mainly due to rupture of unstable plaques, and the role of vascular smooth muscle cells (VSMCs) in this process in IR, Type 2 diabetes mellitus, and metabolic syndrome (T2DM/MetS) has not been fully addressed. Therefore, the role of VSMC survival in the generation of unstable plaques in T2DM/MetS and the involvement of inflammatory mediators was investigated. Methods and results Defective insulin receptor substrate 2 (IRS2)-mediated signalling produced insulin-resistant VSMCs with reduced survival, migration, and higher apoptosis than control cells. Silencing…

Terlipressin or vasopressin plus transdermal nitroglycerin in a treatment strategy for digestive bleeding in cirrhosis

1994

Between 1988 and 1990 an unblinded, randomized trial of terlipressin or vasopressin plus transdermal nitroglycerin, as part of a treatment strategy including emergency sclerotherapy for actively bleeding varices, was conducted during 165 admissions in 137 patients with cirrhosis and upper digestive bleeding. Eighty-four patient admissions were assigned to terlipressin (2 mg every 6 h) and 81 to vasopressin (0.4 to 0.8 unit per min) plus transdermal nitroglycerin (20 to 80 mg). The two groups were comparable for relevant clinical data, but there were slightly more patients with hepatocellular carcinoma or terminal conditions in the terlipressin group. After the 24-h study period, failure to …

Transpenile Venenokklusion zur Therapie der erektilen Impotenz

1989

In 15 of 18 patients, 2 of them with previous surgery, transpenile venoablation was performed for treatment of erectile dysfunction due to cavernous leakage. In 4 this was combined with retrograde venooclusion via the internal iliac vein. In 4 patients normal erectile status could be obtained. In 3 other patients erections became possible with use of intracavernous vasoactive agents. In two only mild amelioration, and in two others no change of erectile dysfunction were obtained. Follow-up studies are yet missing in 3 patients. Complications of the procedure were not observed.
