Introduction: Aldosterone synthase participates in the key reactions of aldosterone synthesis – 11-hydroxylation, 18-hydroxylation and, finally, 18-oxidation. In recent works devoted to evaluating the effectiveness of hybrid steroids in the differential diagnosis of subtypes of primary aldosteronism (PA), it is worth emphasizing the experience of using high-performance liquid chromatography – tandem mass spectrometry (HPLC-MS/MS), which allows detecting even very low...

Objective: To determine the incidence of endometrium pathology in women with autoimmune thyroid pathology and history of reproductive losses, including an assessment of histological images and immunohistochemical (IHC) analysis of the endometrial receptor status.Materials and methods: A prospective cohort study included a clinical and instrumental examination of 84 women aged 18 to 45 years with a history of 1 to 3 consecutive pregnancy losses. Patients ...

Background: During pregnancy, the physiology of the thyroid gland undergoes important changes. As a result, change levels of thyroid hormones. In the latest clinical guidelines, experts have recommended to perform population-based studies to determine reference intervals for thyroid hormones.Aim: To evaluate the reference intervals of free thyroxine in different trimesters of pregnancy in women living in regions with mild iodine deficiency.<p class="...

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...

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: 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...

Relevance: Question of standards of iodine intake in pregnant and lactating women remains relevant.Aim of study: to determine status and function of thyroid gland in pregnant and lactating women with and without antibodies to thyroid gland, on the background of taking different doses of iodine in 3 different regions of Russia with different iodine status.Materials and methods: This study included 414 women in the different trimeste...

The goal was todetermine the optimal methods of postoperative monitoring of serum thyroglobulin (Tg) in differentiated thyroid cancer (DTC). This research intended to compare the prognostic value of immunometric methods with different functional sensitivity (FS) for Tg measurement for detecting recurrent disease.Design: During 2010–2012 years, 76 patients with treated DTC (a total thyroidectomy and adjuvant radioiodine therapy) were included. All p...
