ABSTRACT Serum thyroxine concentrations were determined in 66 euthyroid, 30 hyperthyroid and 13 hypothyroid patients using both the established Murphy method and a simplified method of competitive protein binding analysis. A diagnosis compatibility of 96% was found with both methods indicating that the simplified method has comparable clinical application as an initial screen of thyroid status.

INTRODUCTION. In patients with CKD stage 5 receiving hemodialysis as the main method of renal replacement therapy (RRT), the endocrine system organs, including the thyroid gland, are affected over time. The study of changes in the thyroid status is an urgent task. AIM OF STUDY. Study of functional and gender characteristics of the thyroid status, depending on the duration of patients stay on hemodialysis. PATIENTS AND METHODS. The thyroid status was measured in 108 patients (44 women and 64 men, average age 51.7±15.4 years) undergoing hemodialysis. Patients were divided into quartiles according to the duration of stay on the RRT: group 1 4 – 25 months (28 people), group 2 41 – 59 months (26 people), group 3 68 – 97 months (26 people) and the fourth more than 100 months (28 people). We performed correlation analysis and comparison between groups on the level of free T 4, TSH, the ratio of fT4 to TSH. RESULTS. The average value of fT4 was 11.95±2.07 pmol / ml and TSH 1.5± 0.94 mcME/ml. Significant differences in thyroid status were obtained between the first and second groups in terms of TSH level and ratio fT 4 to TSH (P<0.01) – the level of TSH in the second group is higher (0.74 to 2.1 mсME/ml) and the ratio of fT4 to TSH is lower (13.09 to 4.91). In total, thyroid dysfunction was detected in 20.3% of the examined patients. CONCLUSION. Thus, deviations in the thyroid status occur after 2 years of being on RRT by hemodialysis. In patients who have been on RRT for more than 5 years, the thyroid status stabilizes. The reasons for this phenomenon are completely incomprehensible.

Abstract Background Long-term antithyroid drug therapy has become one of the options for treatment of Graves’ hyperthyroidism. The aim of this study was to compare thyroid status in those who discontinued methimazole (MMI) treatment after 12.8 years with those who continued MMI as long as 24 years. Methods Fifty nine patients with Graves’ disease on long-term MMI for 14.2 ± 2.9 years were recruited; 32 patients (54%) decided to discontinue MMI and 27 (46%) preferred additional years of MMI treatment. All patients were followed for a mean of 6 additional years. Results Of 27 patients who continued MMI up to 24 years, suppressed serum thyrotropin (TSH) was not observed in any patient after the seventh year of treatment. Serum free thyroxine, triiodothyronine, TSH and TSH receptor antibody concentrations remained normal up to the length of the study. Mean daily dose of MMI to maintain TSH in the reference range decreased gradually and reached to 2.8 ± 1.7 mg by 24 years of MMI treatment. No adverse reaction related to MMI occured during additional years of therapy. In 32 patients who discontinued MMI, hyperthyroidism relapsed in 6 patients (19%), one left follow-up and 25 (78%) remained euthyroid during the study. Conclusions Long-term low dose MMI treatment may be a lifelong effective and safe therapeutic modality in patients with Graves’ hyperthyroidism for prevention of relapse, if studies from other centers confirm findings of this research.

AbstractThe current study aimed to identify correlative and regressive dependencies between the water iodine concentration and the levels of TSH (thyroid-stimulating hormone), thyroglobulin antibodies (TgAbs), and thyroid peroxidase (TPOAb) in the serum of 168 in patients (34 men and 134 women) with a hypothyroid form of Hashimoto’s thyroiditis who use water from the supply network and individual wells. Based on the water iodine concentration, low and moderate degrees of iodine endemia in the location of the patients were determined. In the groups of men and women using water from different water supply sources, there were direct correlations between the water iodine concentrations and the TgAbs and TPOAb titers as well as an inverse dependence between iodine and TSH levels. Multivariate regressive analysis indicated that TgAb and TSH in the group of women using water from a supply network and TPOAb titers in the group of women using well water were independent factors associated with water iodine concentrations. Statistically significant correlations and regressive dependencies between the water iodine concentrations and the biomarkers of the thyroid status of the patients indicate the risk of Hashimoto’s thyroiditis progression, especially among women with additional iodine intake.

Background: Amiodarone treatment is effective against various types of arrhythmias but is associated with adverse effects affecting, among other organs, thyroid function. Amiodarone-induced thyroid dysfunction was not thoroughly evaluated in children as it was in adults, yet this affection may lead to irreversible neurodevelopmental complications. Our study aimed to define the incidence and risk factors of amiodarone-induced thyroid dysfunction in children. Methods: The study was designed as an observational study with a retrospective clinical series of 152 children treated by amiodarone in the Pediatric Cardiology Unit of our center from 1990 to 2019. All patients were divided into three groups according to their thyroid status: euthyroid, AIH (amiodarone-induced hypothyroidism) or AIT (amiodarone-induced thyrotoxicosis). Patients from these three groups were compared in terms of key clinical and therapeutic features. Results: Amiodarone-induced thyroid dysfunction was present in 23% of patients. AIT (5.3%) was three times less common than AIH (17.7%), and its occurrence increased with older age ( p < 0.05), treatment dosage ( p < 0.05), treatment duration ( p < 0.05) and the number of loading doses administered ( p < 0.05). There were no distinctive clinical features between euthyroid and AIH groups. A multivariable prediction model of AIT was built, with a yield of 66.7% as positive predictive value and 96.7% as negative predictive value. Conclusion: We observed that one in five children developed amiodarone-induced thyroid dysfunction. Special attention is required for older children with a high dosage and long-term therapy and who received a large number of loading doses, since these children are at risk to develop AIT, which is more delicate to manage than AIH.
