Изучение естественного течения субклинического гипотиреоза и оценка факторов риска его перехода в явный. В исследование были включены 87 пациентов (12 мужчин, 75 женщин) со спонтанно развившимся повышением уровня ТТГ при нормальном уровне свободного Т4; никто из них до этого не получал терапию препаратами тиреоидных гормонов, йода, а также тиреостатическую терапию, лечение радиоактивным йодом и не имел хирургических вмешательств на щитовидной железе. Результаты. Наиболее значимыми факторами риска развития явного (манифестного) гипотиреоза (повышенный ТТГ и сниженный Т4) были носительство антител к щитовидной железе (отношение шансов — 3,99), а также относительно высокий исходный уровень ТТГ (&gt;8 мЕд/л) (отношение шансов — 4,77). Возраст и пол пациентов, а также продолжительность анамнеза СГ не оказывала значимого влияния на вероятность развития явного гипотиреоза. Заключение. Хотя работа не рассматривает проблемы заместительной терапии субклинического гипотиреоза, при решении вопроса о ее целесообразности могут учитываться такие прогностические факторы, как носительство антител к щитовидной железе и уровень ТТГ.</p></abstract><trans-abstract xml:lang="en"><p>Objectives of this retrospective study were to evaluate the natural course of subclinical hypothyroidism (SH) and to estimate possible predictable factors of overt hypothyroidism. Population of the study was selected from the patients with spontaneously elevated thyrotropin (TSH) and normal free thyroxin (fT4) levels. Overall 87 patients (12 male, 75 female) with SH without any therapy with thyroid hormones or iodide drugs or without previous thyroid surgery, thyrostatic therapy, or radioactive iodine therapy were included in the analysis. Results: the main risk factors of overt hypothyroidism in this population were positive thyroid antibodies (odds ratio = 3.99) and high initial level of TSH (&gt;8 mU/l) (odds ratio = 4.77). Patient’s age, gender or duration of SH did not affect significantly the risk of overt hypothyroidism. Conclusions: rational substitutive therapy with thyroid hormones was not discussed in this study, however the data suggest that positive thyroid antibodies and relatively high TSH level may be useful to decide upon such therapy in individuals with SH. Key words: hypothyroidism, Hashimotos, thyroiditis, thyrotropin.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Фадеев В.В., Мельниченко Г.А.
