Незначительные изменения в концентрации ТТГ позволяют заподозрить нарушения работы щитовидной железы еще до клинических проявлений, что повышает ценность корректного и своевременного измерения данного показателя. В клинической практике эндокринолога нередко встречается феномен макропролактинемии; куда менее известным и реже встречающимся феноменом является макротиротропинемия (макро-ТТГ). Наличие комплексов макро-ТТГ возможно заподозрить при определении в сыворотке крови нетипично высоких значений ТТГ при референсных значениях свободного тироксина без каких-либо признаков гипотиреоза. Поскольку в основе феномена лежит аутоиммунный механизм, макро-ТТГ может нередко определяться при аутоиммунном тиреоидите (АИТ). В данной статье представлены клинические случаи пациентов с сочетанием феномена макро-ТТГ и первичного гипотиреоза в исходе АИТ.</p></abstract><trans-abstract xml:lang="en"><p>Thyroid stimulating hormone (TSH) is one of the key indicators in the diagnosis of the thyroid gland functional disorders. Minor changes in TSH concentration make it possible to suspect thyroid dysfunction even before clinical manifestations, which increases the value of correct and timely measurement of it. In the clinical practice, an endocrinologist often encounter the well-known phenomenon of macroprolactinemia; a much less common phenomenon is macrotyrotropinemia (macro-TSH). The presence of macro-TSH complexes can be suspected when the serum detects atypically high TSH values with reference values of FT4 without any signs of hypothyroidism. Since the phenomenon is based on an autoimmune mechanism, macro-TSH can often be detected in patients with autoimmune thyroiditis (AIT). This article presents clinical cases of patients with a combination of the macro-TSH phenomenon and primary hypothyroidism due to AIT.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тиреотропный гормон</kwd><kwd>аутоиммунный тиреоидит</kwd><kwd>левотироксин</kwd><kwd>макро-ТТГ</kwd><kwd>макротиреотропинемия</kwd><kwd>полиэтиленгликоль-преципитация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thyroid stimulating hormone</kwd><kwd>autoimmune thyroiditis</kwd><kwd>Levothyroxine</kwd><kwd>macro-TSH</kwd><kwd>macrothyrotropinemia</kwd><kwd>polyethylene glycol precipitation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Panday P, Arcia Franchini AP, Iskander B, et al.
