Pregnant women are at risk of developing diseases associated with deficiency of essential micronutrients.Objective: To assess the prevalence of vitamin D deficiency among pregnant women and its dependence on the trimester of pregnancy.Methods: We examined 476 pregnant women at different gestational periods from three regions of Russia (Moscow, Ivanovo, Smolensk). Concentration of 25(OH)vitamin D (ng/ml) was estimated by immunometri...

Introduction: CYP11B2 is a key enzyme of primary aldosteronism, and several factors are involved in the regulation of CYP11B2 expression and the overproduction of aldosterone. Somatic mutations in aldosterone-driver genes are strongly associated with CYP11B2 expression and have been only detected in the CYP11B2-positive tumor area, indicating that aldosterone producing adenoma (APA) intratumoral heterogeneity corresponds to non-uniform CYP11B2 expression in neoplastic cells. I...

Objective: The aim of the study was to assess the effectiveness and safety of long-term sibutramine therapy in routine clinical practice.Materials and methods: In total, 98 774 patients (82.3% women, 17.7% men), from 142 cities of the Russian Federation were enrolled in the PRIMAVERA program. The mean age of the patients was 39.39±10.38 years, the mean body weight was 99.1±14.28 kg, and the mean BMI was 35.7±4.41 kg/m2. Physicia...

Introduction: Obesity and type 2 diabetes mellitus (T2DM) are commonly associated with coronary artery disease (CAD). Recent studies demonstrated that microRNAs (miRNAs) are involved in the pathogenesis of CAD.Aim: To study miRNA-26a, microRNA-33a and microRNA-33b expression in patients with obesity.Methods: MiRNAs were detected in peripheral blood samples of 66 patients, aged 48–65 years. Patients with BMI 30.0–39.9 kg/m...

Introduction: Lymphoma of the thyroid gland is an uncommon condition occurring primarily in older women. Most patients have a short history of enlarging thyroid or a neck mass causing tracheal compression. There is also a strong association between thyroid lymphoma and Hashimoto’s thyroiditis. The diagnosis is established by biopsy. The conventional approach to treatment is combination of radiation therapy with multi-agent chemotherapy, while there is no significant role ...

Introduction: Obesity and diabetes mellitus type 2 (T2DM) are considered as one of the major risk factor for coronary heart disease (CHD) development, but the mechanisms beyond this relationship still need to be clarified. miRNAs are supposed to be involved in regulatory mechanisms in this relationship.Aim: To determine miRNAs expression in patients with obesity and T2DM.Methods: MiRNAs were detected in peripheral blood of 43 patie...

Introduction: Obesity and type 2 diabetes mellitus (T2DM) are associated with cardiovascular diseases (CVD). Fibrotic changes in obesity include several molecular processes, including activation of Transforming growth factor β (TGF-β). Recent data indicate the involvement of Fibroblast growth factor 21 (FGF-21) as an important metabolic regulator, and even biomarker of metabolic changes in obesity and T2DM.Aim: To determine TGF-β and FGF-2...

Introduction: Morbid obesity (MO) is associated with high frequency of type 2 diabetes mellitus (T2DM). Biliopancreatic diversion (BPD) is bariatric operation that results in rapid T2DM remission and increased GLP-1 levels. The aim of the study was to compare non-diabetic MO patients with normal weight controls and with patients who underwent BPD more than 2 years ago.Methods: Blood glucose levels, IRI, GLP-1, GIP and glucagon were measured during the or...

Introduction: Renin-angiotensin-aldosterone system (RAAS) plays a significant role in the development of arterial hypertension (AH) in obese patient. Angiotensinogen expression in adipose tissue decreases during fasting and increases in case of overeating, that leads to changes in blood pressure (BP). The aim of the study was to assess the impact of obesity on the activity of RAAS and its role in the development of hypertension.Methods: 60 women, mean ag...

Introduction: One of the manifestations of Munchausen syndrome is the deliberate injection of insulin to achieve hypoglycemia or artificial hypoglycemia. If human insulin is injected, we will always determine high level of insulin and low level of Cpeptideatthemomentofhypoglycemia. Incasesof insulin analogues injection the diagnos is maybe difficult when we use analyzers specific only to human insulin: the low level of IRI and C peptide will be determined.<p class="abstext...
