Patients suffering from diabetes type II develop several skin manifestations including cutaneous infections, diabetic dermopathy, diabetic bullae and acanthosis nigricans. Diabetic micro- and macroangiopathy as well as diabetic neuropathy are believed to play a crucial role in the development of diabetic skin disorders. A reduced cutaneous nerve fiber density was reported in diabetic subjects, which subsequently leads to impaired sensory nerve functions. Using an innervated skin model, we investigated the impact of human diabetic dermal fibroblasts and keratinocytes on porcine sensory neurons...

Mitochondrial disorders (MIDs) are usually multisystem disorders (mitochondrial multiorgan disorder syndrome) either on from onset or starting at a point during the disease course. Most frequently affected tissues are those with a high oxygen demand such as the central nervous system, the muscle, endocrine glands, or the myocardium. Recently, it has been shown that rarely also the arteries may be affected (mitochondrial arteriopathy). This review focuses on the type, diagnosis, and treatment of mitochondrial vasculopathy in MID patients...

BACKGROUND: Type 2 diabetes (T2DM) is associated with obesity, insulin resistance and the metabolic syndrome (MetS). In non-diabetic populations, features of metabolic obesity (MO) are observed in a minority of normal-weight (NW) subjects. The cardiometabolic status of metabolically obese but normal-weight (MONW) individuals has not yet been phenotyped in T2DM. PATIENTS AND METHODS: Prevalence and features of MONW were analyzed in 1244 T2DM patients, in whom MONW was identified as a BMI <25...

Diabetic micro- and macroangiopathy are devastating vascular complications that could account for disabilities and high mortality rate in patients with diabetes. Indeed, diabetic nephropathy and retinopathy are the leading causes of end-stage renal failure and acquired blindness, respectively, and atherosclerotic cardiovascular diseases (CVD) accounts for about 60% of death in diabetic subjects. As a result, the average life span of diabetic patients is about 10-15 years shorter than that of non-diabetic subjects...

The diabetic foot is one of the most significant complications of diabetes and is considered to be a major medical, social, and economic problem worldwide. The risk for foot ulceration in patients with diabetes is close to 25% and is also closely related to risk of limb amputation. Diabetic neuropathy, limited joint mobility, micro- and macroangiopathy, and high plantar pressures have been described as the main risk factors for diabetic foot ulceration. Proper diagnosis and adequate therapeutic treatment are considered the cornerstones to prevention of limb amputation and preservation of quality of life in patients with diabetes...

Diabetes mellitus is a global health problem that results in multiorgan complications leading to high morbidity and mortality. Until recently, the effects of diabetes and hyperglycemia on the bone marrow microenvironment-a site where multiple organ systems converge and communicate-have been underappreciated. However, several new studies in mice, rats, and humans reveal that diabetes leads to multiple bone marrow microenvironmental defects, such as small vessel disease (microangiopathy), nerve terminal pauperization (neuropathy), and impaired stem cell mobilization (mobilopathy)...

BACKGROUND: OSAS, a frequently neglected, yet frequent comorbidity in T2DM, is associated with obesity, metabolic syndrome and central fat. OSAS is better documented in males, and this study explored novel gender dimorphisms in T2DM. METHODS: Cross-sectional study: 815 T2DM (541 males; 274 females) classified into OSAS[-] and OSAS[+] were assessed for cardiometabolic risk factors, glucose homeostasis, micro/macroangiopathies, CV risk, autoimmune thyroid disease (AITD); and GAD65 antibodies...

OBJECTIVE: Red blood cell distribution width (RDW) is a biomarker quantifying the variability of red blood cell size in peripheral blood. Elevated RDW has been found to be an independent prognostic factor for cardiovascular events. SSc is characterized by generalized micro- and macroangiopathy. Our aim was to investigate RDW as a potential biomarker for the assessment of the severity of vascular involvement. METHODS: One hundred and sixty-eight consecutive SSc patients--62 with dcSSc and 106 with lcSSc--were investigated at baseline and after 1-year of follow-up...

Diabetes mellitus is an established risk factor for coronary artery disease and ischemic stroke, and can induce micro- and macroangiopathy. Stroke is strongly associated with severe disability and mortality in Japan, and the risk of stroke is 2-4 times higher among patients with diabetes than among matched controls. The abnormal metabolic state in diabetes can cause arterial dysfunction, and patients with diabetes require treatment for each metabolic abnormality to attenuate atherogenesis. Moreover, diabetes affects stroke outcome as well...

Type 2 diabetes mellitus (T2DM) is a metabolic disease caused by insulin resistance that leads to changes in glucose metabolism. Importantly, both insulin resistance and hyperglycemia are present in T2DM patients as a hallmarks of metabolic syndrome. They negatively affect functions of many cells, for example endothelial cells. Endothelial progenitor cells (EPC) is a population of mononuclear cells that expresses endothelial and progenitor markers. EPC are also characterized by ability to form tubes on matrigel, outgrowth into mature endothelial cells, produce proangiogenic factors or take part in the blood vessels formation...

Diabetes mellitus is a systemic lesion of the micro- and macrocirculatory bed. We examined a total of 110 people with type 2 diabetes mellitus and lesions of the major vessels of the lower limbs. Of these, 70 patients were found to have microangiopathy combined with nephropathy. Diabetic nephropathy was classified depending on the level of microalbuminuria and the glomerular filtration rate. All patients were subdivided into three groups: diabetic macroangiopathy of the lower extremities with neither diabetic nephropathy nor chronic renal disease, lower-limb diabetic macroangiopathy combined with diabetic nephropathy in stage 1 of microalbuminuria of chronic renal disease and those in combination with diabetic nephropathy in stage 2 of microalbuminuria chronic renal disease...

In France, 2.8 millions of patients have type 2 diabetes, which is a well-established risk factor for cardiovascular disease. In about 15 years, several large clinical trials tried to study the relationship between a tight glycaemic control and the occurrence of micro- and macroangiopathy. Meta-analyses of targeting intensive versus conventional glycaemic control focused on divergent results. In type 1 diabetes, a tight glycaemic control reduced the occurrence of microangiopathy whereas more time, at least 5 years is needed to reduce macroangiopathy...

Characteristic clinical manifestations of AFD such as acroparesthesias, angiokeratoma, corneal opacity, hypo/ and anhidrosis, gastrointestinal symptoms, renal and cardiac dysfunctions can occur in male and female patients, although heterozygous females with AFD usually seem to be less severely affected. The most prominent CNS manifestations consist of cerebrovascular events such as transient ischaemic attacks (TIAs) and (recurrent) strokes. For the most part, CNS complications in AFD have been attributed to cerebral vasculopathy, including anatomical abnormalities...

The pathophysiology of chronic diabetic ulcers is complex and still incompletely understood, both micro- and macroangiopathy strongly contribute to the development and delayed healing of diabetic wounds, through an impaired tissue feeding and response to ischemia. With adequate treatment, some ulcers may last only weeks; however, many ulcers are difficult to treat and may last months, in certain cases years; 19-35% of ulcers are reported as nonhealing. As no efficient therapy is available, it is a high priority to develop new strategies for treatment of this devastating complication...

INTRODUCTION: CD36 may play an important role in removal of oxidized LDLs from plasma, protein glycation, the pathogenesis of insulin resistance, type 2 diabetes, and diabetic micro- and macroangiopathy. Some reports have pointed to decreased expression of macrophages in association with mutations of the CD36 gene in hyperglycemic and obese subjects. The aim of the study was to search for an association between CD36 gene polymorphism and carbohydrate metabolism disturbances or variability of plasma soluble CD36 concentrations in obese children...
