Background. Vitamin D is a hormone that is mainly produced in the skin upon ultraviolet B radiation exposure and has important influence on various organs. In recent years, data have been collected that vitamin D deficiency plays an important role in the development of various nonskeletal diseases, including autoimmune diseases. Chronic autoimmune thyroiditis (Hashimoto’s thyroiditis) is one of the most common organ-specific autoimmune endocrine diseases. It is characterized by increased level of antithyroid peroxidase and/or antithyroglobulin antibodies in blood, which often leads to thyroid dysfunction and structural changes of the gland. There is an opinion that vitamin D deficiency may be considered as an important risk factor for development of chronic autoimmune thyroiditis, but data of various small studies are controversial. Despite the fact that Georgia is a sunny country, vitamin D deficiency is a widespread problem here. Thyroid diseases, including the chronic autoimmune thyroiditis, are also very common in Georgia. The aim of our research was to compare the level of vitamin D between the patients with chronic autoimmune thyroiditis and the healthy subjects. Methods. This retrospective study enrolled subjects, who were 18–70 years old and visited the clinics “Cortex” and “National Institute of Endocrinology” in 2018 or in 2019 from mid-spring to mid-summer. Data of thyroid-stimulating hormone, free thyroxine, antithyroid peroxidase antibodies, antithyroglobulin antibodies, thyroid ultrasonography, and 25(OH) vitamin D were retrospectively analysed based on medical history. In total, data of 1295 patients were collected. The statistical processing of data was performed through the SPSS 20 program. Results. The negative association between thyroid-stimulating hormone, antithyroid peroxidase antibodies, antithyroglobulin antibodies, heterogeneous parenchyma of thyroid gland, and vitamin D was found in women. Statistically significant association was not detected in men. Conclusions. Serum vitamin D is lower in women with autoimmune thyroiditis and primary hypothyroidism. Further studies are needed to evaluate the influence of vitamin D supplementation on thyroid autoantibody positivity or primary hypothyroidism.

A Prospective Study

ABSTRACT Vitamin D deficiency is a global health problem, its role as an immune modulator being recently emphasized. Recent studies are increasingly suggesting that vitamin D plays a significant role in reducing the incidence and progression of autoimmune diseases. Furthermore, it was reported that patients with Hashimoto’s thyroiditis, an autoimmune thyroid disease had lower vitamin D levels [1]. We initiated a prospective study, for a period of 6 months with a study group represented by 160 patients admitted to the National Institute of Endocrinology “CI Parhon” in the period 2013 -2014. Patients were divided into 3 groups: 121 patients without thyroid pathology, 22 patients diagnosed with chronic autoimmune thyroiditis, who received 2000 IU cholecalciferol daily, 17 patients diagnosed with chronic autoimmune thyroiditis, which did not receive cholecalciferol. We found that patients with chronic thyroiditis have a poor vitamin D status with ATPO values negatively correlating with 25 (OH) vitamin D levels. Treatment with cholecalciferol not only improves vitamin D status but also lowers antithyroid antibodies titres. Keywords: vitamin D deficiency, chronic

The Mean

Abstract.The relationship between Hashimoto’s thyroiditis and vitamin D has been demonstrated in several studies. The aim of the present study was to evaluate vitamin D concentrations in patients with Hashimoto’s thyroiditis, the effect of vitamin D therapy on the course of disease, and to determine changes in thyroid autoantibody status and cardiovascular risk after vitamin D therapy. We included 75 patients with Hashimoto’s thyroiditis and 43 healthy individuals. Vitamin D deficiency is defined as a 25-hydroxy vitamin D (25(OH)D3) concentration less than 20ng/mL. Vitamin D deficient patients were given 50.000 units of 25(OH)D3 weekly for eight weeks in accordance with the Endocrine Society guidelines. All evaluations were repeated after 2 months of treatment. Patients with Hashimoto’s thyroiditis had significantly lower vitamin D concentrations compared with the controls (9.37±0.69 ng/mL vs 11.95±1.01 ng/mL, p < 0.05, respectively). Thyroid autoantibodies were significantly decreased by vitamin D replacement treatment in patients with euthyroid Hashimoto’s thyroiditis. Also, HDL cholesterol concentrations improved in the euthyroid Hashimoto group after treatment. The mean free thyroxine (fT4) concentrations were 0.89±0.02 ng/dL in patients with Hashimoto’s thyroiditis and 1.07±0.03 ng/dL in the healthy control group (p < 0.001). The mean thyroid volumes were 7.71±0.44 mL in patients with Hashimoto’s thyroiditis and 5.46±0.63 mL in the healthy control group (p < 0.01). Vitamin D deficiency is frequent in Hashimoto’s thyroiditis and treatment of patients with this condition with Vitamin D may slow down the course of development of hypothyroidism and also decrease cardiovascular risks in these patients. Vitamin D measurement and replacement may be critical in these patients.

Significant Difference

Introduction: Body weight gain in children and teenagers is one of the major challenges that cause undesirable health outcomes. Simultaneously with the prevalence of overweight and obesity, children and adolescents are diagnosed with 25-hydroxyvitamin D (25(OH)D) deficiency in different sides of the world. The present study aimed to assess 25(OH)D status among Iranian volunteers aged 1-16 years and find the correlation between 25(OH)D status and body mass index (BMI) subjects.    Material and Methods: The total volunteers included 807 Iranian children aged 1 to 16 referred to the general and endocrinology clinics in Babol city, Mazandaran Province. A trained physician determined anthropometric characteristics. Serum levels of calcium (Ca), phosphate (P), creatinine (Cr), urea, thyroxine (T4), thyroid-stimulating hormone (TSH), and 25(OH)D were assessed in all children.      Results: 25.27% of the children were 25(OH)D deficient, and 59.1% were insufficient. There was no significant difference in serum 25(OH)D level between girls and boys (P=0.13). A significant negative correlation was found in serum 25(OH)D level with weight (P=0.000, r=-0.12), BMI (P=0.000, r=-0.13), and age (P=0.000, r=-0.13). Conclusion: These data displayed that 25(OH)D insufficiency is highly prevalent among children in the north of Iran. Serum 25(OH)D levels are affected by age and BMI value. Improving vitamin D deficiency helps to maintain the health of children and adolescents during this critical period.

Objective: While guidelines propose a single elevated prolactin measurement drawn without excess venipuncture stress as sufficient for diagnosing hyperprolactinemia, this may lead to unnecessary evaluation in the setting of stress-induced hyperprolactinemia. In this study, we aimed to define the role of the cannulated prolactin test in confirming hyperprolactinemia. Methods: We conducted a retrospective review of 757 patients with unexplained hyperprolactinemia who performed a cannulated prolactin test in a community-based referral endocrine clinic between 2000–2015. The prolactin test consisted of “test-baseline” levels taken at rest (T0), and cannulated measurements at 60 and 90 minutes (T60 and T90) without repeated venipuncture. The most recent prolactin level performed prior to the test (referral-prolactin) was collected. Results: Referral-prolactin was available for 621 (82%) patients, of whom 324 (52.2%) normalized at T0. The probability of normoprolactinemia at T0 was 50% if referral-prolactin was 2.0-fold the upper-limit-of-normal (ULN), yet only 5% if referral-prolactin was 5.0-fold the ULN. Of the 359 patients with hyperprolactinemia at T0, prolactin normalized at T60 and/or T90 in 99 (27.6%) patients. The probability of normoprolactinemia was low (<5%) in those with T0 prolactin levels >2.4-fold ULN. Overall, of 757 prolactin tests performed, only 260 (34.3%) patients had persistent hyperprolactinemia. Conclusion: Patients with referral-prolactin levels >5.0-fold the ULN, or a rested-prolactin (T0) >2.4-fold the ULN are unlikely to normalize during the cannulated test and consideration should be made to proceed directly with pituitary imaging. In patients with prolactin levels below these thresholds, the cannulated prolactin test may considerably reduce unnecessary investigations, treatment, and cost.
