The follow-up was 26 (10; 61) months. The association of IST without TE (IST; <italic>n</italic>=141) or with TE (IST+TE; <italic>n</italic>=72) with the development of complete (PR), partial (PR) and overall (PR or PR, OR) remissions was investigated.</p> <p><bold>Results. </bold>The incidence of achieving early PR or OR in the IST and IST+TE groups was 65.2% and 86.1%, respectively (<italic>p</italic>=0.002). The probability of early PR or OR was significantly increased in the IST+TE group compared to IST [HR 1.714 (1.214–2.420) and HR 3.410 (1.309–8.880), respectively]. IST+TE was associated with a 3- to 4-fold increase in the likelihood of PR or OR at the end of follow-up [HR 2.575 (1.679–3.950) and HR 4.768 (2.434–9.337), respectively]. Analyses using pseudorandomisation methods yielded similar results.</p> <p><bold>Conclusion. </bold>TE may be effective for remission induction in high-risk IgAN.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель. </bold>Оценить эффективность иммуносупрессивной терапии (ИСТ) и тонзиллэктомии (ТЭ) у пациентов с иммуноглобулин A-нефропатией (IgAN) высокого риска.</p> <p><bold>Материалы и методы. </bold>Ретроспективная когорта исследования включала случаи с диагнозом первичной IgAN (<italic>n</italic>=213; возраст – 34±11 лет, мужчин – 52%) с высоким риском прогрессирования, с клиническими показателями и данными морфологических исследований. Период наблюдения составил 26 (10; 61) мес. Исследовали связь ИСТ без сочетания с ТЭ (ИСТ; <italic>n</italic>=141) или в сочетании с ТЭ (ИСТ+ТЭ; <italic>n</italic>=72) с развитием полной (ПР), частичной и общей (частичной или полной, ОР) ремиссий.</p> <p><bold>Результаты. </bold>Частота достижения ранних ПР или ОР в группах ИСТ и ИСТ+ТЭ составила 65,2 и 86,1% соответственно (<italic>p</italic>=0,002). Вероятность развития ранней ПР или ОР достоверно увеличивалась в группе ИСТ+ТЭ в сравнении ИСТ: отношение рисков 1,714 (1,214–2,420) и 3,410 (1,309–8,880) соответственно. ИСТ+ТЭ ассоциирована с 3–4-кратным увеличением вероятности ПР или ОР в конце наблюдения: отношение рисков 2,575 (1,679–3,950) и 4,768 (2,434–9,337) соответственно.
