G H Tomkin, D Owens
Premature atherosclerosis in diabetes accounts for much of the decreased life span. New treatments have reduced this risk considerably. This review explores the relationship among the disturbances in glucose, lipid, and bile salt metabolic pathways that occur in diabetes. In particular, excess nutrient intake and starvation have major metabolic effects, which have allowed us new insights into the disturbance that occurs in diabetes. Metabolic regulators such as the forkhead transcription factors, the farnesyl X transcription factors, and the fibroblast growth factors have become important players in our understanding of the dysregulation of metabolism in diabetes and overnutrition...

Atherosclerosis is one of the most prevalent reasons for premature death in adults. Despite the several conventional drugs in the market; many patients are not completely treated. Here we comprehensively review current clinical evidence regarding the efficacy of dietary polyphenols in atherosclerosis and related complications. PubMed, Cochrane library and Scopus were searched from inception until August 2016 to obtain clinical trials in which polyphenols were evaluated in cardiovascular parameters related to atherosclerosis...

Werner syndrome is a rare progeroid syndrome caused by the WRN gene mutation. It is characterized by a general appearance of premature aging, diabetes mellitus, and atherosclerosis, and an increased risk of malignancies. We report a patient who presented with hematemesis due to cirrhosis of liver and was subsequently diagnosed with Werner syndrome. Further genetic analysis showed a novel mutation in the WRN gene which has not previously been reported. Werner syndrome should be considered for the cases of liver cirrhosis when accompanied by the features of accelerated aging...

Tobacco exposure including second-hand smoke is the leading preventable cause of premature death in the United States. Serum cotinine, a highly sensitive and specific biomarker for tobacco exposure, is a more accurate measure of tobacco exposure than self-reported smoking status. Although the harmful effect of tobacco exposure on cardiovascular disease (CVD) risk factors (e.g., atherosclerosis) or hard CVD outcomes (e.g., myocardial infarction) is well established, its effect on intermediate outcomes such as subclinical myocardial injury (SMI), especially in nonsmokers, is not clear...

BACKGROUND: Atrial fibrillation and heart failure are 2 of the most common diseases, yet ready means to identify individuals at risk are lacking. The 12-lead ECG is one of the most accessible tests in medicine. Our objective was to determine whether a premature atrial contraction observed on a standard 12-lead ECG would predict atrial fibrillation and mortality and whether a premature ventricular contraction would predict heart failure and mortality. METHODS AND RESULTS: We utilized the CHS (Cardiovascular Health) Study, which followed 5577 participants for a median of 12 years, as the primary cohort...

BACKGROUND: Sitosterolemia is a rare lipid metabolism disorder that involves storage of plant sterols. This disease is associated with atherosclerosis, but detailed vascular endothelial assessment is difficult. CASE PRESENTATION: We report a 5-year-old girl with sitosterolemia who presented with xanthomas at 23 months of age. Her total cholesterol was 868 mg/dL, and her plasma sitosterol level was 9.48 mg/dL. Direct sequencing detected a homozygous mutation in gene ABCG5 (p...

Valvular heart disease frequently occurs as a consequence of premature atherosclerosis in individuals with familial hypercholesterolemia (FH). Studies have primarily focused on aortic valve calcification in heterozygous FH, but there is paucity of data on the incidence of valvular disease in homozygous FH. We performed echocardiographic studies in 33 relatively young patients (mean age: 26 years) with homozygous FH (mean LDL of 447 mg/dL, 73% on LDL apheresis) to look for subclinical valvulopathy. Twenty-one patients had evidence of valvulopathy of the aortic or mitral valves, while seven subjects showed notable mitral regurgitation...

With a long history of application in Chinese traditional medicine, berberine (BBR) was reported to exhibit healthspan-extending properties in some age-related diseases, such as type 2 diabetes and atherosclerosis. However, the antiaging mechanism of BBR is not completely clear. By means of hydrogen peroxide- (H2O2-) induced premature cellular senescence model, we found that a low-concentration preconditioning of BBR could resist premature senescence in human diploid fibroblasts (HDFs) measured by senescence-associated β-galactosidase (SA-β-gal), accompanied by a decrease in loss of mitochondrial membrane potential and production of intracellular reactive oxygen species (ROS)...

BACKGROUND: The MMP (matrix metalloproteinase) family plays diverse and critical roles in directing vascular wall remodeling in atherosclerosis. Unlike secreted-type MMPs, a member of the membrane-type MMP family, MT1-MMP (membrane-type 1 MMP; MMP14), mediates pericellular extracellular matrix degradation that is indispensable for maintaining physiological extracellular matrix homeostasis. However, given the premature mortality exhibited by MT1-MMP-null mice, the potential role of the proteinase in atherogenesis remains elusive...

BACKGROUND: Thrombocytosis and inflammation are vital elements in the pathogenesis of atherosclerosis. The platelet-to-lymphocyte ratio (PLR) is a novel biomarker that combines these parameters and has been shown to be associated with cardiovascular disease (CVD). This study aimed to determine whether PLR correlates with coronary artery disease (CAD) in high-risk patients, and if the relationship is affected by age. METHODS: Consecutive patients referred for coronary angiogram were evaluated (n=822)...

Cardiovascular diseases remain the leading cause of death worldwide and account for most of the premature mortality observed in chronic inflammatory diseases. Common mechanisms underlie these two types of disorders, where the contribution of Interleukin (IL)-17A, the founding member of the IL-17 family, is highly suspected. While the local effects of IL-17A in inflammatory disorders have been well described, those on the cardiovascular system remain less studied. This review focuses on the effects of IL-17 on the cardiovascular system both on isolated cells and in vivo...

Familial hypercholesterolaemia (FH) is a common genetic disorder that causes elevated low-density lipoprotein (LDL)-cholesterol levels from birth. Untreated FH accelerates atherosclerosis and predisposes individuals to premature coronary artery disease (CAD) in adulthood. Mendelian randomization studies have demonstrated that LDL-cholesterol has both a causal and cumulative effect on the risk of CAD. This supports clinical recommendations that children with FH commence pharmacological treatment from age 8-10 years, to reduce the burden of hypercholesterolaemia...

BACKGROUND: Sitosterolemia (STSL) is a recessive inherited disorder caused by pathogenic variants in ABCG5 and ABCG8 genes. Increased levels of plasma plant sterols (PS) usually produce xanthomas and premature coronary atherosclerosis, although hematological abnormalities may occasionally be present. This clinical picture is unfamiliar to many physicians, and patients may be at high risk of misdiagnosis. OBJECTIVES: To report two novel ABCG5 gene variants causing STSL in a Spanish patient, and review the clinical and mutational landscape of STSL...

BACKGROUND: Familial hypercholesterolemia is one of the most common inherited metabolic diseases and is an autosomal dominant disorder meaning heterozygotes, or carriers, are affected. Those who are homozygous have severe disease. The average worldwide prevalence of heterozygous familial hypercholesterolemia is at least 1 in 500, although recent genetic epidemiological data from Denmark and next generation sequencing data suggest the frequency may be closer to 1 in 250. Diagnosis of familial hypercholesterolemia in children is based on elevated total cholesterol and low-density lipoprotein cholesterol levels or DNA-based analysis, or both...

The relationship between chronic hemolysis with subsequent iron overload, inflammation, and premature atherosclerosis has been documented in hemolytic anemias, particularly β-thalassemia. However, no such relationship has been established in sickle cell disease (SCD). We sought to evaluate SCD as a risk factor for early vascular insult by measuring carotid intima-media thickness (CIMT) and plasma chitotriosidase and to assess the role of the latter as a potential quantitative indicator of vascular inflammation and atherogenesis...

The surfaces of the human body are heavily populated by a highly diverse microbial ecosystem termed the microbiota. The largest and richest among these highly heterogeneous populations of microbes is the gut microbiota. The collection of microbes and their genes, called the microbiome, has been studied intensely through the past few years using novel metagenomics, metatranscriptomics, and metabolomics approaches. This has enhanced our understanding of how the microbiome affects our metabolic, immunologic, neurologic, and endocrine homeostasis...

Myeloproliferative neoplasms (MPN) include three main entities: Polycythemia Vera (PV), Essential Thrombocythemia (ET), and Myelofibrosis (MF). MPN represent a unique model of the relationship between the clonal development of a hematologic malignancy and chronic inflammation. The neoplastic clone is the main driver of this inflammatory reaction as demonstrated by the curative effect of allogeneic stem cell transplantation which leads not only to a complete restore of the hematopoiesis, but also to regression of bone marrow fibrosis...

BACKGROUND: Patients with type 1 diabetes mellitus (T1DM) are at risk for premature atherosclerosis (AS), which has its origin in childhood. Carotid intima-media thickness (IMT) is an established surrogate marker for subclinical AS in adults. The first macroscopically detectable AS changes, however, begin in the abdominal aorta. Advanced glycation end products (AGE) predict microvascular complications in diabetes. OBJECTIVES: To assess the sensitivity for early macrovascular changes of brachial, femoral, and aortic IMT compared to conventional carotid IMT in pediatric T1DM patients ; and the relationship of IMT with AGE...

BACKGROUND AND AIMS: High low-density lipoprotein (LDL)-cholesterol levels are a major cause of premature coronary heart disease (CHD) and death in patients with familial hypercholesterolemia (FH). It is uncertain whether these risk factors affect men and women equally. We aimed to compare the risk factors of carotid plaques, which are reliable surrogates of coronary atherosclerosis, in men and women with FH. METHODS: 154 patients with FH (40.9% men) were included, diagnosed according to Simon Broome criteria...
