Impact of chronic diuretic treatment on glucose homeostasis
2013
Background The use of diuretics for hypertension has been associated with unfavorable changes in cardiovascular risk factors, such as uric acid and glucose tolerance, though the findings in the literature are contradictory. Methods This study investigated whether diuretic use is associated with markers of metabolic and cardiovascular risk, such as insulin-resistance and uric acid, in a cohort of adults without known diabetes and/or atherosclerotic cardiovascular disease. Nine hundred sixty-nine randomly selected participants answered a questionnaire on clinical history and dietary habits. Laboratory blood measurements were obtained in 507 participants. Results Previously undiagnosed type 2 …
Inverse association between type 2 diabetes and aortic root dimension in hypertensive patients
2017
Background Some data support the concept that aortic root diameter (ARD) in hypertension may be regarded as a marker of subclinical organ damage. The impact of type 2 diabetes mellitus (DM) on cardiac structure and function is known, although the relationship between DM and ARD is not clear. The aim of our study was to evaluate the influence of DM on ARD in hypertensive patients. Methods We enrolled 1693 hypertensive patients (aged 63.7 ± 9.6 years). The population was divided into two groups: the first one with DM (n = 747) and the second one without DM (n = 946). ARD was measured by echocardiography at level of Valsalva's sinuses using echocardiography M-mode tracings. It was considered a…
Long-term efficacy of lipoprotein apheresis and lomitapide in the treatment of homozygous familial hypercholesterolemia (HoFH): a cross-national retr…
2021
Abstract Background Homozygous familial hypercholesterolemia (HoFH) is a rare life-threatening condition that represents a therapeutic challenge. The vast majority of HoFH patients fail to achieve LDL-C targets when treated with the standard protocol, which associates maximally tolerated dose of lipid-lowering medications with lipoprotein apheresis (LA). Lomitapide is an emerging therapy in HoFH, but its place in the treatment algorithm is disputed because a comparison of its long-term efficacy versus LA in reducing LDL-C burden is not available. We assessed changes in long-term LDL-C burden and goals achievement in two independent HoFH patients’ cohorts, one treated with lomitapide in Ita…
Simultaneous endovascular treatment of synchronous symptomatic acute type B aortic dissection and large infrarenal aortic aneurysm. Technical tips an…
2020
Highlights • Acute type B aortic dissection associated with AAA, has a high rupture risk. • This complicated dissection must be considered for treatment as quickly. • This approach can be performed endovascularly when supraaortic trunks are involved. • Totally endovascular solution to address both disease is feasible.
Uncoupling Protein 2 as genetic risk factor for systemic lupus erythematosus: association with malondialdehyde levels and intima media thickness
2020
BACKGROUND Increased oxidative stress potentially leads to accelerated atherosclerosis and, consequently, cardiovascular diseases, the main cause of death in systemic lupus erythematous (SLE). To gain insight into these mechanisms, we studied the association of uncoupling protein (UCP) 2 genetic variants, gene involved in the mitochondrial production of reactive oxygen species, and oxidative stress with SLE and the presence of atherosclerosis. METHODS Genetic analysis of the UCP2 -866G/A and UCP2 Ins/Del polymorphisms was performed in 45 SLE patients and 36 healthy controls by RFLP-PCR. Oxidation status was determined by measuring malondialdehyde (MDA) levels. Presence of subclinical athero…
Cerebriform sebaceous nevus: a subtype of organoid nevus due to specific postzygotic FGFR2 mutations.
2021
Background Postzygotic mutations in FGFR2 have been identified in mosaic forms of acne, keratinocytic epidermal nevi, nevoid acanthosis nigricans / rounded and velvety epidermal nevus and in two fetuses with papillomatous pedunculated sebaceous nevus (PPSN). Objectives To determine the clinical and genetic characteristics of children with cerebriform, papillomatous, and pedunculated variants of sebaceous nevi. Methods Infants diagnosed with sebaceous nevi characterized by a cerebriform, papillomatous, and/or pedunculated morphology over a 10-year period (2010 - 2019) at three pediatric dermatology centers in Switzerland and France were included in this case series. Clinical and histological…
Growth and differentiation factor 11 (GDF11): Functions in the regulation of erythropoiesis and cardiac regeneration
2015
International audience; Members of the TGF-β superfamily transduce their signals through type I and II receptor serine/threonine kinases. The binding of activins to activin type IIA (ActRIIA) or type IIB (ActRIIB) receptors induces the recruitment and phosphorylation of an activin type I receptor (ALK4 and/or ALK7), which then phosphorylates the Smad2 and Smad3 intracellular signaling proteins. The regulation of members of the TGF-β family is known to be complex, because many proteins able to bind the ligands and inhibit their activities have been identified. Growth and differentiation factor 11 (Gdf11) belongs to the TGF-β family. GDF11, like other members of the TGF-β superfamily, is prod…
Lipid triad or atherogenic lipoprotein phenotype: a role in cardiovascular prevention?
2005
The term "lipid triad" or "atherogenic lipoprotein phenotype" has been introduced to describe a common form of dyslipidemia, characterized by three lipid abnormalities: increased plasma triglyceride levels, decreased HDL-cholesterol concentrations and the presence of small, dense LDL particles. It has been suggested that the clinical importance of the atherogenic lipoprotein phenotype probably exceeds that of LDL-cholesterol, because many more patients with coronary artery disease are found to have this trait than hypercholesterolaemia. There is a body of evidence that therapies effective against plasma HDL-cholesterol and triglycerides are associated with a strong reduction of cardiovascul…
Update on the role of the atherogenic lipoprotein phenotype in cardiovascular prevention
2009
Higher plasma triglyceride levels and decreased HDL-cholesterol concentrations are usually accompanied by the presence of small, dense LDL in the so-called lipid triad or ‘atherogenic lipoprotein phenotype’. This phenotype is highly atherogenic and its prevalence may suggest an even higher overall burden of atherosclerotic disease as compared with that associated with hypercholesterolemia. As stated by the National Cholesterol Education Program Adult Treatment Panel III, there is evidence suggesting each component of this lipid triad is individually atherogenic. However, the relative contribution of each component cannot be easily determined. Therefore, it has been suggested to consider th…
Should we measure routinely the LDL peak particle size?
2004
Low density lipoproteins (LDL) do not show in humans a normal distribution and comprise two different main fractions: large, buoyant (phenotype pattern A) and small, dense (phenotype pattern B) particles, that differ not only in size and density but also in physicochemical composition, metabolic behaviour and atherogenicity. The prevalence of small, dense LDL changes with age (30-35% in adult men, 5-10% in men <20 years and in pre-menopausal women, 15-25% in postmenopausal women) and is genetically influenced, with a heritability ranging from 35% to 45%. Small, dense LDL correlate negatively with plasma HDL levels and positively with plasma triglyceride levels and are associated with the me…
