AIM: The aim of this study was to determine the effect of satiety on TSH and free thyroxine levels.Methods: This study was conducted in a tertiary hospital. According to previous TSH and thyroxine levels, groups of 30, 30 and 60 participants were designated as subclinical hypothyroidism, hypothyroidism, and control groups respectively. To obtain TSH and thyroxine results first phlebotomy was performed at 8 am while participants were in fasting state. Then participants were allowed to have non-standardized breakfast. Second phlebotomy was performed at 10 am while participants were in non-fasting state. Paired t-test and ANOVA were used to analyze the data.Results: The fasting TSH levels of the participants (2.57 ± 1.84 mlU/L) were significantly higher than the satiety TSH levels (2.04 ± 1.48 mlU/L) (t = 8.566, p < 0.001, d = 0.80). The fasting free thyroxine values (1.31 ± 0.38 mg/dl) of the participants were significantly lower than the satiety free thyroxine values (1.39 ± 0.35 mg/dl) (t = -1.988, p = 0.049, d = 0.20).Conclusion: Knowing how TSH and free thyroxine tests are affected by satiety has the power to affect treatment of many patients. Our study has shown that both TSH and free thyroxine levels changed significantly according to satiety status.","PeriodicalId":10284,"journal":{"name":"Clinical and experimental thyroidology","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83238294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main symptoms of hyper-cortisolism are obesity, osteoporosis, cardiomyopathy, muscle atrophy, skin thinning and purple stretch marks (striae) on the body. In practice, obesity and osteoporosis are the most frequent symptoms that are found in 90% of cases. However, there are some patients with an implicit clinical picture of hypercorticism. Some cases might concomitant with exophthalmos. This review describes a rare symptom of hypercortisolism — exophthalmos. Exophthalmos is a pathological protruding of eyeballs. This symptom is known in the context of TED that occurs most commonly in patients with Graves' disease. The article compares the mechanisms of development of eye symptoms in Cushing's syndrome and thyroid diseases, especially the Graves' disease. It discusses possible molecular mechanisms leading to exophthalmia in patients with Cushing's syndrome. Factors affecting adipogenesis in vitro and in vivo are studied, in particular factors leading to an increase of orbital fatty tissue against of elevated cortisol levels. Hormonal signaling and transcription cascades responsible for adipocyte differentiation into mature fat cells are presented. Other orbital manifestations of hypercortisolism, which occur relatively rare in practice, are also discussed in the article. These include glaucoma as well as cataract, Lisha nodules and central serous chorioretinopathy. Clinical cases of Cushing's syndrome with different ocular manifestations are considered and appropriate conclusions have been drawn.","PeriodicalId":10284,"journal":{"name":"Clinical and experimental thyroidology","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85786760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comparison of the similarities and differences between the clinical guidelines from the ATA and ACOG can serve to highlight areas of uncertainty where additional studies are needed and may also demonstrate areas where endocrinologists and obstetricians may elect differing approaches to clinical care. The ACOG and ATA guidelines recommend similar approaches to the interpretation of thyroid function testing during gestation and to the management of thyroid cancer, thyroid nodules, gestational thyrotoxicosis, and postpartum thyroiditis Both strongly recommend levothyroxine (L-T4) treatment for overtly hypothyroid pregnant women, and both recommend against the use of T3-containing thyroid hormone preparations when treating hypothyroidism in pregnancy.","PeriodicalId":10284,"journal":{"name":"Clinical and experimental thyroidology","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76648116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These interferences can affect measurement of analyte which leads to misinterpretation and subsequent wrong clinical decisions, the probability of which is about 1%. However, the scale of the problem may be greater due to the lack of awareness to the problem among doctors and the lack of laboratory screening for interfering factors. These factors can be both endogenous and exogenous, bind both to antibodies to the analyte and to the reagent in the test system. The specificity of the immunoassay depends not only on the binding properties of antibodies, the activity of reagent, but also on the composition of the test system and the format of the methodology (non-competitive two-site or “sandwich” and competitive assays).\u0000This review provides a description of the main interferences that can affect the measurement of thyroid hormones, in particular thyroid stimulating hormone, free thyroxine and triiodothyronine, calcitonin, and demonstrates clinical cases reported in the literature over the past few years.","PeriodicalId":10284,"journal":{"name":"Clinical and experimental thyroidology","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82095574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deficiency of one or more essential vitamins and minerals is usually the result of poor nutrition and / or insufficient absorption of micronutrients as a result of infectious and inflammatory diseases. It is possible that the deficiency of certain trace elements, in turn, can aggravate iodine deficiency and contribute to dysfunction of the thyroid gland. There are assumptions about the relationship between the content of iodine, selenium, iron, zinc in the human body and the level of thyroid hormones. Zinc is a vital trace element for all living organisms, participating in many biochemical processes in cells, including cell differentiation and division, its growth, cell transport, transcription, protein synthesis, RNA and DNA synthesis, and DNA replication. Its role as an antioxidant and participation in the functioning of both innate (T, NK and NKT cells) and adaptive immunity (anti-inflammatory cytokines) are very important. This review will consider the role of zinc in the synthesis and metabolism of thyroid hormones.","PeriodicalId":10284,"journal":{"name":"Clinical and experimental thyroidology","volume":"47 1","pages":"25-30"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77143149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
