Цель. Оценить эффективность иммуносупрессивной терапии (ИСТ) и тонзиллэктомии (ТЭ) у пациентов с иммуноглобулин A-нефропатией (IgAN) высокого риска. Материалы и методы. Ретроспективная когорта исследования включала случаи с диагнозом первичной IgAN (n=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; n=141) или в сочетании с ТЭ (ИСТ+ТЭ; n=72) с развитием полной (ПР), частичной и общей (частичной или полной, ОР) ремиссий. Результаты. Частота достижения ранних ПР или ОР в группах ИСТ и ИСТ+ТЭ составила 65,2 и 86,1% соответственно (p=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. Анализы с применением методов псевдорандомизации дали аналогичные результаты. Заключение. ТЭ может быть эффективна для индукции ремиссии при IgAN высокого риска.
Aim.To evaluate the efficacy of immunosuppressive therapy (IST) and tonsillectomy (TE) in patients with high-risk IgA nephropathy (IgAN). Materials and мethods. The retrospective study cohort included cases with primary IgAN (n=213, age 34±11 years, male 52%) at high risk of progression with clinical and morphological data collected. The follow-up was 26 (10; 61) months. The association of IST without TE (IST; n=141) or with TE (IST+TE; n=72) with the development of complete (PR), partial (PR) and overall (PR or PR, OR) remissions was investigated. Results. The incidence of achieving early PR or OR in the IST and IST+TE groups was 65.2% and 86.1%, respectively (p=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. Conclusion. TE may be effective for remission induction in high-risk IgAN.
