Inflammation and impaired endothelium-dependant vasodilatation in non obese women with gestational diabetes mellitus: preliminary results
2013
International audience; BACKGROUND: To evaluate whether abnormal endothelial function, a common finding in gestational diabetes mellitus (GDM) pregnancies, can be explained by inflammatory cytokines. METHODS: Forearm skin blood flow (FSBF), into response to acetylcholine (Ach) (endothelium-dependent vasodilatation), were measured in 24 pregnant control subjects and 28 gestational diabetes mellitus (GDM) women, in the third trimester of gestation. A fasting glycemic and lipidic panel was obtained, and inflammatory cytokines (TNF-alpha and IL-6) and adiponectin were also determined. RESULTS: FSBF is significantly reduced in GDM group compared with control subjects (344.59 +/- 57.791 vs.176.38…
Sarcopenia and appendicular muscle mass as predictors of impaired fasting glucose/type 2 diabetes in elderly women
2021
Elderly women exhibit a high risk of type 2 diabetes (T2D), but no definitive data exist about the possible role of postmenopausal increases in visceral adiposity, the loss of lean body mass, or decreases in the sum of the lean mass of arms and legs (appendicular skeletal muscle mass (ASMM)). This retrospective, longitudinal study investigated whether body composition (bioelectrical impedance analysis) predicted the development of impaired fasting glucose (IFG) or T2D in a cohort of 159 elderly women (age: 71 ± 5 years, follow-up: 94 months) from southern Italy (Clinical Nutrition and Geriatric Units of the “Mater Domini” University Hospital in Catanzaro, Calabria region, and the “P. Giacco…
Extracellular Vesicle Encapsulated MicroRNAs in Patients with Type 2 Diabetes Are Affected by Metformin Treatment
2019
Recently, microRNAs (miRNAs) in circulating extracellular vesicles (EVs), have emerged as a source of potential biomarkers for various pathophysiological conditions, including metabolic disorders such as diabetes. Type 2 diabetes mellitus (T2DM), is the most prevalent form of diabetes in the USA, with 30 million diagnosed patients. Identifying miRNA biomarkers that can be used to assess response to glucose lowering treatments would be useful. Using patient plasma samples from a subset of the Danish Metagenomics of the Human Intestinal Tract (MetaHIT) cohort, we characterized miRNAs from whole plasma, plasma-derived EVs, and EV-depleted plasma by small RNA-sequencing to identify T2DM associa…
Thyroïdites : où en est-on en 2019 ?
2020
Thyroiditis is a frequent and mostly benign disease that can sometimes disrupt the thyroid balance. Their diagnosis, as well as their aetiology, is a necessary step in the management of the patients. Painful thyroiditis includes acute thyroiditis of infectious origin and subacute thyroiditis. The first one can be treated by antibiotics or antifungals depending on the germ found. The second one will be treated with non-steroidal anti-inflammatory drugs or corticosteroids. In cases of Hashimoto's thyroiditis with overt hypothyroidism, replacement therapy with L-thyroxine will be adapted to the TSH level. As amiodarone treatment provides dysthyroidism, the thyroid status should be monitored re…
New antihyperglycaemic agents and cardiovascular disease: let's be optimistic.
2018
Cardiovascular disease (CVD) substantially increases mortality in diabetes mellitus. This narrative review highlights recent research on the putative associations between dipeptyl peptidase 4 inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium glucose co-transporter 2 inhibitors (SGLT-2is) and several cardiovascular risk factors.New antihyperglycaemic agents favourably modulate several CVD risk factors, including fasting and postprandial plasma glucose levels, body weight, blood pressure, lipids, microalbuminuria, nonalcoholic fatty liver disease, serum uric acid, and arterial stiffness. Liraglutide (in LEADER), semaglutide (in SUSTAIN-6), empagliflozin (in EMPA-REG …
Thyroid Stimulating Hormone Receptor Antibodies in Thyroid Eye Disease-Methodology and Clinical Applications.
2018
Background Thyroid stimulating hormone receptor antibodies (TSHR-Ab) cause autoimmune hyperthyroidism and are prevalent in patients with related thyroid eye disease (TED). Purpose To provide a historical perspective on TSHR-Ab and to present evidence-based recommendations for clinical contemporary use. Methods The authors review the recent literature pertaining to TSHR-Ab in patients with TED and describe the various immunoassays currently used for detecting TSHR-Ab and their clinical applications. Results We provide a historical summary and description of the various methods used to detect TSHR-Ab, foremost, the functional TSHR-Ab. Increasing experimental and clinical data demonstrate the …
Glucose lowering and anti-atherogenic effects of incretin-based therapies: GLP-1 analogues and DPP-4-inhibitors
2009
Type 2 diabetes is a chronic, progressive disease with a multi-faceted pathophysiology. Beyond the known defects of insulin resistance and beta-cell insufficiency, derangement of incretin hormones normally produced from the gut wall in response to food intake play an important role. In recent years, the 'incretin-based' therapies (IBTs) have been developed to address hyperglycemia through either mimicking the action of the endogenous incretin glucagon-like polypeptide (GLP-1) (GLP-1 receptor agonists) or by inhibiting the activity of the enzyme that degrades GLP-1 (the dipeptyl peptidase-4 inhibitors).We reviewed available evidence on the glucose lowering and anti-atherogenic effects of IBT…
Comparative Effectiveness of DPP-4 Inhibitors Versus Sulfonylurea for the Treatment of Type 2 Diabetes in Routine Clinical Practice: A Retrospective …
2018
Introduction DPP-4 inhibitors (DPP4i) and sulfonylureas are popular second-line therapies for type 2 diabetes (T2D), but there is a paucity of real-world studies comparing their effectiveness in routine clinical practice. Methods This was a multicenter retrospective study on diabetes outpatient clinics comparing the effectiveness of DPP4i versus gliclazide extended release. The primary endpoint was change from baseline in HbA1c. Secondary endpoints were changes in fasting plasma glucose, body weight, and systolic blood pressure. Automated software extracted data from the same clinical electronic chart system at all centers. Propensity score matching (PSM) was used to generate comparable coh…
A Novel Long-Term Graves’ Disease Animal Model Confirmed by Functional Thyrotropin Receptor Antibodies
2020
<b><i>Introduction:</i></b> A novel long-term murine model for Graves’ disease (GD) using repeated, long-term immunizations with recombinant adenovirus expressing the extracellular A-subunit of the human thyrotropin receptor (Ad-TSHR) was applied to evaluate the functional anti-TSHR-antibody (TSHR-Ab) profile. <b><i>Methods:</i></b> BALB/c mice received 7 immunizations with either 10<sup>10</sup> plaque-forming units of Ad-TSHR or control Ad-GFP. Naïve (nonimmuized native) mice were also studied. Three 3-weekly immunizations were followed by 4-weekly boosts until the 7th immunization. Blocking (TBAb) and stimulating (TSAb) TSHR-Ab …
Personality types in individuals with type 1 and type 2 diabetes
2020
Objective The Type A personality, characterized by impatience, strong career ambition and competitiveness, is associated with greater sensitivity to external stress. Type 1 diabetes (T1D) is an auto-immune disease, which is potentially influenced by stress, unlike type 2 diabetes (T2D). The aim of this study was to assess whether individuals with T1D and T2D exhibited significant differences on the Type A personality scale. We also assessed personality in patients with thyroid auto-immune diseases to validate potential links between auto-immune disease and Type A personality. Design and methods The Bortner questionnaire was used to assess Type A personality in 188 patients with T1D, 430 pa…
