Лабораторные методы диагностики являются основными инструментами в практике врача любой специальности, в том числе эндокринолога. Были определены факторы, способные изменять концентрацию биологически активной фракции исследуемого вещества, в последующем затрудняющие интерпретацию лабораторных результатов и принятие верного клинического решения. В литературе представлено описание множества циркулирующих аутоантител, участвующих в связывании с гормонами гипофиза (пролактином (ПРЛ), тиреотропным (ТТГ), соматотропным, лютеинизирующим, фолликулостимулирующим и адренокортикотропным гормонами), гипоталамуса (вазопрессином и окситоцином), поджелудочной железы (инсулином и глюкагоном), околощитовидных желез (паратиреоидным гормоном), а также с гормонами щитовидной железы. Как правило, образуемые макромолекулы приводят к повышению лабораторных показателей, в которых превалирующая фракция гормона не обладает биологической активностью, что и определяет основную проблему данного феномена. К наиболее часто встречаемым вариантам относят иммунные комплексы с ПРЛ и ТТГ, вызывающие феномены макропролактинемии и макротиротропинемии (макро-ТТГ-­емии/макро-ТТГ) соответственно. Большинство лабораторных тест-систем, используемых в клинической практике, способны определять лишь общее количество ПРЛ и ТТГ.

В представленном клиническом наблюдении описано сочетание феноменов макро-ТТГ и макропролактинемии у пациента с аутоиммунным тиреоидитом (АИТ) и витилиго.

Laboratory diagnostic methods are the main tools in the practice of a doctor of any specialty, including an endocrinologist. Factors were identified that could change the concentration of the biologically active fraction of the test substance, subsequently complicating the interpretation of laboratory results and making the right clinical decision. The literature describes a variety of circulating autoantibodies involved in binding to pituitary hormones (prolactin (PRL), thyroid-stimulating hormone (TSH), growth hormone, luteinizing, follicle-stimulating, and adrenocorticotropic hormones), hypothalamus (vasopressin and oxytocin), pancreas (insulin and glucagon) , parathyroid glands (parathyroid hormone), as well as with thyroid hormones. As a rule, the resulting macromolecules lead to an increase in laboratory parameters, in which the prevailing fraction of the hormone does not have biological activity, which determines the main problem of this phenomenon. The most common variants include immune complexes with PRL and TSH, causing the phenomena of macroprolactinemia and macrothyrotropinemia (macro-TSH-emia/macro-TSH), respectively. Most laboratory test systems used in clinical practice are capable of determining only the total amount of PRL and TSH. The presented clinical observation describes a combination of the phenomena of macro-TSH and macroprolactinemia in a patient with autoimmune thyroiditis (AIT) and vitiligo.
