Treatment With Bempedoic Acid and/or Its Fixed-dose Combination With Ezetimibe in Hypercholesterolemia or Mixed Dyslipidemia

The primary objective is to describe in the real-world setting patient characteristics and outcomes of patients with primary hypercholesterolaemia (heterozygous familial and non-familial) or mixed dyslipidaemia using bempedoic acid and/or its fixed-dose combination with ezetimibe in managing plasma levels of low-density lipoprotein cholesterol (LDL-C). Secondary objectives are to document and evaluate as applicable: Assessment of the cardiovascular risk of patients treated with bempedoic acid and/or its fixed-dose combination with ezetimibe using different risk scores (e.g. SMART score for Very High Risk patients and Framingham risk score for High Risk patients. The scores will be re-calculated during the analysis and used as an analytical tool only). Changes in low-density lipoprotein cholesterol (LDL-C) levels prior to treatment with bempedoic acid and/or its fixed-dose combination with ezetimibe compared to 1 year follow-up and subsequent data collection points, if applicable. Characterize plasma levels of other potentially ASCVD-modifying cholesterol fragments, namely, LDL-C, total cholesterol (TC), apolipoprotein B (apoB), high-density lipoprotein cholesterol (HDL-C), non-HDL-C, triglycerides (TGs) and lipoprotein A (Lp[a]) compared to 1 year follow-up and subsequent data collection points, if applicable. Changes in the levels of inflammatory marker hsCRP compared to 1 year follow-up and subsequent data collection points, if applicable. Adverse Drug Reactions associated to bempedoic acid and/or its fixed-dose combination with ezetimibe. Changes in uric acid levels compared to 1 year follow-up and subsequent data collection points, if applicable. Relevant CV events: Myocardial infarction Unstable angina Coronary artery bypass graft surgery (CABG) Percutaneous transluminal coronary angioplasty (PTCA) Stroke Transient ischemic attack (TIA) Acute peripheral arterial occlusion All-cause death Cardiovascular (CV)-death Adverse effects associated with lipid-modifying treatment (LMT) Laboratory abnormalities Muscle-associated symptoms New onset and/or worsening diabetes Changes in the patients´ glycemic status over time Site characteristics (sites and practitioners) caring for patients treated with bempedoic acid and/or its fixed-dose combination with ezetimibe. Use of LMTs prior or concomitantly to receiving bempedoic acid and/or its fixed-dose combination with ezetimibe (therapies including combination treatments). Bempedoic acid and/or its fixed-dose combination with ezetimibe treatment parameters such as treatment duration by therapy, dosage, prescription intervals, permanent discontinuations, switches and reasons for these, (concomitant medication, additional therapy/interventions). Healthcare resource use especially consultation visits with specialist, nurse time and hospitalizations as well as patient-reported outcome using EQ-5D-5L and PAM-13.

Plant Sterol INtervention for Cancer Prevention (PINC)

Several types of human cells convert cholesterol into other molecules, including oxysterols. Oxysterols can promote breast cancer growth and help tumours to spread. Some breast cancer types recruit other cells (host cells) able to produce oxysterols within the local cancer environment. How these other cells help breast tumours metastasize or resist chemotherapy is not well understood, but epidemiological and clinical studies suggest elevated LDL-C is associated with worse survival, poorer response to therapy and an increased propensity for disease relapse in breast cancer patients. In this trial the investigators will test how an LDL-C lowering dietary intervention (using commercially available phytosterol added food products), alters the ability of non-cancer cells (adipocytes, fibroblasts and macrophages) collected from high LDL-C volunteers to change chemotherapy response and metastatic process in breast cancer cells. In this trial, volunteers with high LDL-C levels will be recruited by the University of Leeds, and divided randomly into two arms that cross over. The experimental period (yogurt drink enriched with phytosterols) and placebo period (non-enriched yogurt drink) will each last for 8 weeks, alternated with a 4 weeks of wash-out period. Samples will be collected 4 times (week-0, week-8, week-12, week-20) during the study and will include blood, white blood cells (macrophages), and fat tissue cells. Measurements will include oxysterol, LDL-C and phytosterol concentrations (volunteers' serum/plasma, media from the host cells/breast cancer experimental culture) and how the host cells alter the behaviour of cancer cells in the laboratory.

Effects of Atorvastatin in Graves' Orbitopathy (GO)

Graves' orbitopathy (GO) is the most common extra-thyroidal manifestation of Graves' disease (GD), being observed in ~25% of patients. Besides genetic and demographical variables, risk factors associated with the development of GO in GD patients are known to be inadequate control of hyperthyroidism, radioiodine treatment, and smoking. In a large retrospective study conducted in more than 8,000 individuals with GD it was observed that treatment with 3-hydroxy-3-methylglutaryl-coenzyme reductase inhibitors, better known as statins, is associated with a ~40% reduced risk of developing GO in GD patients. The findings were interpreted as the consequence of the anti-inflammatory action of statins, being GO notoriously an autoimmune, inflammatory conditions. Statins are widely used for the treatment of hypercholesterolemia, for which they are quite effective. The possibility that their "protective" effect in terms of GO development in GD patients, as observed by Stein et al., was simply due to their hypolipemic actions was not considered. To evaluate the possibility that the findings reflected lowering of cholesterol rather than a direct anti-inflammatory effect of statins a prospective, observational study to assess the association between GO and high cholesterol levels and/or the relationship between the degree and/or activity of GO and hypercholesterolemia is ongoing. Preliminary findings suggest that GO is more severe and active in patients with high cholesterol levels. On the basis of these observations, the present randomized clinical trial was designed to be performed in hypercholesterolemic patients with GD and moderate-to-severe and active GO, aimed at investigating if lowering of cholesterol levels with statins is associated with a better outcome of GO.
