BACKGROUND: Studies on the relationship between thyroid autoimmunity and serum trace elements (TE) are ongoing in different parts of the world, however, the data obtained are often contradictory, which determines the relevance of this study. AIM: The aim of the study was to identify associations between thyroid status and Anti-Thyroid Peroxidase antibodies (TPOAb) with serum TE among young women. MATERIALS AND METHODS: The study participants were 859 women aged 18–45, whose Thyroid-Stimulating Hormone (TSH) was in the reference range or above 3.4 µIU/ml and with free Thyroxine (fT4) in the reference range. The exclusion criteria were the presence of menopause and decompensation of chronic diseases. The participants were subdivided into 2 groups: a group of women with TPOAb less than 30 U/ml, designated as TPOAb(-), and a group of women with TPOAb more than 30 U/m, designated as TPOAb (+). The detection of TSH, fT4, and TPOAb in serum was provided by enzyme immunoassay on the Evolis Robotized System using “Thyroid — ELISA- TSH, 0.23–3.4 µIU/ml”, “Thyroid — ELISA free T4, 10–23.2 pmol/l”, “Thyroid ELISA — TPOAb<30 U/ml” test systems. The reference values were taken from the instructions of the manufacturer Alkor Bio group (Russia). Logistic regression analysis was applied to adjudge associations between TPOAb status and serum trace elements. RESULTS: The level of fT4 was lower in the AT-TPO (+) group compared to the AT-TPO (-), p=0.006; Triglycerides, aspartate aminotransferase, alkaline phosphatase was higher in the AT-TPO (+) group compared to the AT-TPO (-). There were more smoking women in the AT-TPO group (-) 4.1% versus 1.3% in AT-TPO (+). It was found that, after adjusting for likely cofounding factors, participants with antibody positivity had significantly lower concentrations of selenium; zinc, iodine, iron. When serum trace elements levels were analyzed in tertiles, the odds ratios TPOAb positivity of tertile 1 were higher that of tertile 3. CONCLUSION: The associations between TPOAb and microelements demonstrate their involvement in autoimmune processes in the thyroid gland.

BACKGROUND: Hypofunction of the thyroid gland in women at the pre-pregnancy stage and during pregnancy is associated with a high risk of congenital hypothyroidism in children, as a result of which irreversible changes in the nervous system are formed. Despite the mandatory intake of potassium iodide preparations, pregnant women often develop gestational hypothyroidism, which requires the appointment of levothyroxine. Many women have episodic hypofunction of the thyroid gland before pregnancy, associated with various factors. Diagnosed hypothyroidism requires hormonal correction. The recommended dose of levothyroxine calculated by the patient’s weight is not always adequate to achieve TSH targets. In addition, there are pharmacological factors. Levothyroxine sodium preparations differ in bioavailability. The stability of drugs is affected by external factors and the composition of fillers from different manufacturers of drugs. AIM: To assess the dependence of TSH reduction on the method of taking levothyroxine in a population of pregnant women. MATERIALS AND METHODS: Statistical analysis and prospective study was carried out from 2019 to 2021. On the basis of the «Perinatal Center», Tyumen, women’s consultative and diagnostic department. Pregnant women with diagnosed primary subclinical and manifest hypothyroidism in the first trimester of pregnancy (n=76) were selected for cohort observation. All pregnant women were prescribed L-thyroxine Berlin-hemi. Other levothyroxine preparations were not used in order to exclude distortion of the results of the study. RESULTS: Pregnant women with hypothyroidism were divided into two groups according to the method of taking L-thyroxine: oral (n=54) and sublingual (n=22). A month later, TSH normalization was observed in 41 pregnant women in the oral group (76%) and in 22 pregnant women in the sublingual group (100%). Women who did not achieve hypothyroidism compensation were recommended sublingual administration without increasing the dose of L-thyroxine, provided that TSH was no higher than 4.0 mcME / ml. A TSH study a month later showed that all pregnant women achieved compensation. CONCLUSION: Based on the conducted research, it is shown that the more rational administration of levothyroxine sodium preparations is sublingual, since there is a slightly alkaline reaction in the oral cavity, which does not have a destructive effect, like gastric juice.

SUBSTANTIATION. It is known that about 69% of all thyroid nodules undergoing surgical treatment are benign formations, and up to 75% of patients with an intermediate cytological conclusion undergo unnecessary surgical intervention. This suggests that improving the quality of differential diagnosis of nodular formations will avoid excessive economic costs for the healthcare system. In this regard, AI technologies in diagnostic algorithms for the classification of thyroid nodules were involved. AIM. Improving the efficiency of automatic classification of thyroid nodules on ultrasound images by using a set of neural network models. MATERIALS AND METHODS. We used ultrasound images of thyroid nodules available in open sources and obtained with the help of 3 ultrasound devices of Endocrinology Research Centre as part of Project № 22-15-00135 of the grant of the Russian Science Foundation. This article check the hypothesis that the size of the training set cannot be increased by repeating similar images from the ultrasound cine loop of one patient, but only by expanding the dataset with new unique specimens of other patients and/or data from the augmentation process. RESULTS. As a result, a neural network model EfficientNet-B6 was proposed to solve the problem of EU-TIRADS classification of thyroid nodules based on ultrasound images of the thyroid gland. CONCLUSION. The results obtained allow us to advance in the use of artificial intelligence methods for personalized medicine in thyroid diseases.

OBJECTIVES . Diffuse and nodular goiter are the most common thyroid gland (thyroid) diseases in children and adults living in iodine-deficient regions. Thyroid hormone potentiates progressive hypertrophy and hyperplasia of thyrocytes, with uneven proliferation of thyroid cells leading to nodule formation. Iodine deficiency, which promotes replication of thyroid follicular cells, also increases the incidence of TSH Receptor mutations, leading to receptor activation and autonomous functioning of follicles. AIM . To evaluate and describe ultrasound and cytologic thyroid nodes in the regions in Russia with proven iodine deficiency. MATERIALS AND METHODS . The study was conducted in regions with proven iodine deficiency in the Central and North Caucasian Federal Districts. Population of conditionally healthy adult volunteers (mean age — 47.5 years) was recruited as part of visiting events to screen for the occurrence of thyroid nodes. RESULTS . The results obtained indicate a high prevalence of multinodular colloid goiter in adult patients living in conditions of chronic iodine deficiency. In the Chechen Republic, the prevalence of nodular thyroid pathology was found in 64.5% (205/318) of cases, and in the Tula region — in 40.6% (116/286). In the studied sample the results of cytologic examination confirmed the presence of colloid thyroid masses in 97% (60/62) — Bethesda category II; in 3% (2/62) of patients nodular masses had Bethesda IV. Diffuse goiter prevalence in the examined population was 20.8%. CONCLUSIONS . A study indicates a high prevalence of iodine-deficient thyroid disease — multinodular colloid goiter in regions with proven chronic iodine deficiency. The wide prevalence of goiter with colloid and cystic components is confirmed by the cytologic examination with different ultrasound characteristics according to the EU-TIRADS classification. The obtained data correspond to the official statistics demonstrating high prevalence of nontoxic goiter in adults in the examined regions, which is an important argument confirming the need for systemic iodine prophylaxis.

Levothyroxine steadily maintains its position as the «gold standard» in the treatment of hypothyroidism. Despite the possibility of step-by-step tableted dose titration of levothyroxine, the results of many studies reliably point to the fact that a significant number of patients do not reach the target level of thyroid hormone. One of the main reasons for the therapy ineffectiveness is the inconvenience of levothyroxine sodium regimen for many patients, associated with the need to observe certain time intervals before meals and other medications. The above-mentioned factors have stimulated a number of studies aimed at developing new dosage forms with significant advantages in the pharmacokinetics and pharmacodynamics of drugs. The review provides the latest data on the new dosage forms of levothyroxine. Further large-scale clinical trials are needed for a more reasonable and widespread use of new dosage forms of levothyroxine in clinical practice.
Subacute thyroiditis is an inflammatory disease of the thyroid gland. Clinical manifestations include pain or discomfort in the neck, a painful diffuse goiter, and a transient episode of hyperthyroidism. We describe the case of a 48-year-old woman who had no symptoms characteristic of subacute thyroiditis. The test results were consistent with a clinical diagnosis of secondary hypothyroidism. The patient had a history of asymptomatic COVID-19 episode 6 months ago and neck pain one month ago. This case demonstrates the importance of a detailed history, comprehensive examination, and correct interpretation of laboratory and instrumental findings in making the diagnosis.

Given the widespread iodine deficiency, diffuse and diffuse nodular euthyroid goiter is an urgent problem. A large goiter needs to be highlighted both from the perspective of possible complications for the patient, including a decrease in the quality of life and compression syndrome, as well as from the perspective of the complexity of surgical treatment, given the technical complexity of the operation and the high probability of intraoperative and postoperative complications. The article describes a clinical case of a patient admitted to the endocrinology department with a diagnosis of diffuse nodular goiter of the 2nd degree for examination with complaints of a huge deforming formation of the neck contours, difficulty breathing when walking and during sleep. It is known from the anamnesis that the patient has been observed for about 10 years by an endocrinologist with nodular goiter. The patient was repeatedly offered surgical treatment, which he categorically refused. In the Department of endocrinology, the patient underwent a comprehensive examination to assess the condition and function of the thyroid gland, as well as to identify possible complications.

AIM: To study anthropometric, biochemical and hormonal characteristics of women aged 25-44 with different levels of thyroid- stimulating hormone, prolactin and leptin.MATERIALS AND METHODS: From a representative sample of the young population of the Oktyabrsky district of Novosibirsk aged 25-44 years (840 women), a group of women (n=655) was selected to study cardiometabolic and hormonal parameters. The design of the study was a cross-sectional, observational, single-centre study. All participants underwent determination of anthropometric parameters (weight, measurement of waist circumference (WC) and hips (HC), calculation of BMI), systolic and diastolic blood pressure (SBP, DBP), biochemical parameters (total cholesterol (TC), high-density lipoprotein cholesterol ( HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), fasting plasma glucose (FPG), creatinine, calculation of glomerular filtration rate (GFR).Statistical processing was carried out using the SPSS-13 package.RESULTS: The study included 655 women, mean age 36.3±5.4 years, mean BMI 25.0±5.7 kg/m2. Young women showed direct associations of TSH with HC (r=0.115, p<0.05), TG (r=0.145, p<0.010) and inverse association with GFR (r=-0.129, p<0.05). PRL is inversely associated with HC (r=-0.109, p<0.05). Of all the studied hormones, leptin is most associated with anthropometric and biochemical parameters in young women. Thus, leptin is directly associated with WC (r=0.562, p<0.0001), HC (r=0.589, p<0.0001), WC/HC index (r=0.309, p<0.0001), BMI ( r=0.582, p<0.0001), as well as levels of SBP (r=0.293, p<0.0001), DBP (r=0.274, p<0.0001), TC (r=0.123, p=0.018), TG (r=0.234, p<0.0001), FPG (r=0.150, p=0.004), inversely related to HDL-C (r=-0.225, p<0.0001).CONCLUSION: The metabolic status of women aged 25-44 is associated with the level of TSH, leptin. It is advisable to determine TSH, leptin in young women with abdominal obesity for the purpose of dynamic monitoring and correction.

Iodine is the most important trace element in the human body. Its main function is to participate in the synthesis of thyroid hormones, thyroxine (T4) and triiodothyronine (T3). The main source of iodine for humans is food rich in this trace element. The iodine content in foods varies greatly. The main sources of iodine are seafood, iodized salt, seaweed, as well as dairy products and egg yolks. In addition, iodine is found in a number of drugs for external and internal use, dietary supplements, and in iodinated contrast agents.Low-iodine diet (less than 50 μg per day) is prescribed before radioactive iodine therapy (RAIT) for thyroid diseases, namely hyperthyroidism and differentiated thyroid cancer. Currently, there is no consensus on the clinical benefits of such a diet, especially in countries with iodine deficiency, such as Russia.The aim of this review is to assess the need for a low-iodine diet and its optimal duration, as well as to determine the clinical characteristics affecting the outcome of RAIT, based on data from recent studies.
