К настоящему времени не существует общепринятого алгоритма радиойодтерапии (РЙТ) тиреотоксикоза.</p></sec><sec><title>Цель</title><p>Цель: оценить результат применения I131 при тиреотоксикозе с использованием фиксированной активности 550 МБк, а также изучить факторы, влияющие на результаты лечения.</p></sec><sec><title>Методы</title><p>Методы. Мы изучили результаты назначения фиксированной активности 550 МБк I131 у 38 пациентов (35 женщин и 3 мужчины) с тиреотоксикозом. Пациенты были разделены на две группы – имевших БГ и ОТЗ/МТЗ. Отмена антитиреоидных препаратов проводилась за 7–14 дней до проведения РЙТ. Период наблюдения варьировал от 6 до 8 мес, в среднем составил 6,6 ± 0,4 мес.</p></sec><sec><title>Результаты</title><p>Результаты. В целом по изучаемой группе через полгода после проведения РЙТ 23 пациента (61%) достигли гипотиреоза, у 7 пациентов (18%) наблюдался эутиреоз, тиреотоксикоз сохранялся у 8 пациентов (21%). У пациентов с БГ наступление гипотиреоза было значительно более частым, чем у пациентов с ОТЗ/МТЗ (75 vs 35,7% соответственно, p &lt; 0,001). При ОТЗ/МТЗ была также выше частота эутиреоза (28,6 vs 12,5%). Предикторами положительного ответа на лечение являлись объем щитовидной железы (&lt;30 мл для женщин, &lt;40 мл для мужчин) и молодой возраст (до 35 лет). Значимого влияния на результат лечения длительности тиреотоксикоза, уровня антител к рецептору тиреотропного гормона не выявлено.</p></sec><sec><title>Выводы</title><p>Выводы. В исследовании показано, что при РЙТ фиксированной активностью 550 МБк I131 эффективность лечения различна при БГ и ОТЗ/МТЗ. Помимо того, на результат лечения влияли возраст пациентов и объем щитовидной железы, что необходимо учитывать при планировании РЙТ. Необходимо продолжить изучение эффективности и безопасности РЙТ на большем числе клинических наблюдений и более длительном периоде наблюдения. В целях повышения эффективности РЙТ тиреотоксикоза целесообразна персонализация тактики лечения с учетом клинических факторов, а также применение in vivoдозиметрического планирования при расчете терапевтической активности.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Radioiodine therapy (RIT) is an alternative method to surgical treatment used in the treatment of hyperthyroidism (Graves’ disease or solitary/multinodular toxic goiter (STG/MTG) etiology). However, treatment protocol doesn’t exist.</p></sec><sec><title>Aim</title><p>Aim. To evaluate the outcomes of the I131 treatment in hyperthyroidism using the standard dose (550 Mbq), and to explore the factors that influence the outcome of treatment.</p></sec><sec><title>Methods</title><p>Methods. We studied 38 patients (35 women and 3 men) with hyperthyroidism. Each patient was carried I131 RIT in a dose of 550 Mbq. Patients were randomized 2 group – patients with Graves&amp;apos; disease and patients with a solitary/multinodular toxic goiter. Antithyroid drugs withdraw was usually conducted for 7–14 days prior to RIT. Follow-up period ranged from 6 to 8 months, the average was 6.6 ± 0.4 months.</p></sec><sec><title>Results</title><p>Results. Six months after the RIT 23 patients (61%) reached hypothyroidism, 7 patients (18%) was observed euthyroidism, thyrotoxicosis stayed in 8 patients (21%). In patients with Graves&amp;apos; disease onset hypothyroidism were more likely (75% vs 35.7%, p &lt; 0.001). Thus at STG/MTG achieve euthyrosis percentage was higher (28.6% vs 12.5%). Predictors of a positive outcome of the treatment are: less thyroid size (&lt;30 ml for women, &lt;40 ml for men) and younger age (under 35 years old). Statistical significance in influencing the outcome of treatment by disease duration, level of stimulating antibodies against thyrotropin receptors have not been identified.</p></sec><sec><title>Conclusions</title><p>Conclusions. Fixed activity of 550 MBq I131 has a different efficacy in the treatment of hyperthyroidism in patients with Graves’ disease and STG/MTG. In addition, on treatment results affect patient age and the size of the thyroid gland, which should be considered during planning RIT. In order to improve the effectiveness of radioiodine therapy of hyperthyroidism requires personalization tactics of treatment based on clinical factors, as well as the use of in vivo dosimetry planning when therapeutic activity calculating.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тиреотоксикоз</kwd><kwd>радиойодтерапия</kwd><kwd>I131</kwd><kwd>активность 550 МБк</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hyperthyreosis</kwd><kwd>Radioiodine therapy</kwd><kwd>I131</kwd><kwd>550 MBq</kwd><kwd>fixed dose</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">Franklyn JA, Daykin J, Holder R, Sheppard MC.
