Материалы и методы. Ретроспективная когорта исследования включала случаи с диагнозом первичной IgAN (n=367, возраст
34±12 лет, мужчин – 55%). Использовали демографические и клинические показатели на момент биопсии почки, данные светооптического и иммуноморфологического исследований. Период наблюдения составил 26 (10; 61) мес. Регистрировали развитие ремиссии (полной или частичной) и прогрессирование IgAN (начало диализа или снижение скорости клубочковой фильтрации ≥50% от исходной. Все больные получали лечение блокаторами ренин-ангиотензиновой системы. Оценку эффективности терапии проводили с применением методов псевдорандомизации по индексу соответствия (propensity score – PS) – подбором групп по PS, регрессией с PS в качестве независимой ковариаты и взвешивание по 1/PS. Сравнивали группы пациентов на ИСТ (n=176) и
без ИСТ (n=191), с ТЭ (n=63) и без ТЭ (n=304) в 4 подгруппах: 1) без ИСТ и без ТЭ (ИСТ-ТЭ-; n=162); 2) ТЭ без ИСТ (ИСТ-ТЭ+; n=29); 3) ИСТ без ТЭ (ИСТ+ТЭ-; n=142); 4) ИСТ и ТЭ (ИСТ+ТЭ+; n=34).
Результаты. Все использованные PS-методы дали близкие оценки сравнительной эффективности лечения в разных подгруппах:
1) больные на монотерапии кортикостероидами и комбинированной терапии кортикостероидами в сочетании с другими иммуносупрессантами не имели достоверных отличий по рискам прогрессирования IgAN (Expβ=0,919; 95% доверительный интервал 0,333–2,950) и достижения ремиссии (Expβ=0,919; 95% доверительный интервал 0,379–2,344) и объединены в общую группу ИСТ;
2) ИСТ достоверно связана с вероятностями снижения темпов прогрессирования и развития ремиссии IgAN; 3) позитивные эффекты ИСТ ограничены случаями с суточной потерей белка более 2 г; 4) вероятности ремиссии и прогрессирования IgAN существенно не отличались между группами ТЭ+ и ТЭ-, ИСТ-ТЭ+ и ИСТ-ТЭ-. В группе ИСТ+ТЭ+ случаев прогрессирования не выявлено; кумулятивная почечная выживаемость выше (vs ИСТ+ТЭ-; р=0,010), а вероятность ремиссий не отличалась.
Заключение. ИСТ может быть эффективна для индукции ремиссии и торможения прогрессирования IgAN у пациентов с суточной протеинурией более 2 г, а проведение ТЭ в дополнение к ИСТ ассоциировано с дополнительным снижением риска прогрессирования болезни.

Aim. An evaluation of the effectiveness of immunosuppressive therapy (IST) and tonsillectomy (TE) in patients with IgA nephropathy (IgAN).
Materials and methods. A retrospective cohort of the study included cases with biopsy proven primary IgAN (n=367, age 34±12 years, men – 55%). We used demographic and clinical and morphological parameters at the time of biopsy. Median followup period was 26 (10; 61) months. Outcomes were remission (complete or partial) and the progression of IgAN (defined as the start of dialysis or a decrease in glomerular filtration rate ≥50% from baseline). All patients received treatment with renin angiotensin system blockers. Evaluation of the effectiveness of therapy was carried out using propensity score (PS) methods – matching, conventional double robust regression models with PS as independent covariate, and inverse probability weighting. Following patient subgroups were used for comparative analyses: with IST (n=176) and without IST (n=191); with TE (n=63) and without TE (n=304); without IST and without TE (IST-TE-; n=162); with TE and without IST (IST-TE+; n=29); with IST and without TE (IST+TE-; n=142); with IST and with TE (IST+ TE+; n=34).
Results. All PS methods used gave close estimates of the comparative effectiveness of treatment in different subgroups: 1) patients on monotherapy with corticosteroids (CS) and combination of CS with other immunosuppressants did not have significant differences in probabilities of IgAN progression (hazard ratio 0.919; 95% CI 0.333–2.950) and remission (odds ratio 0.919; 95% CI 0.379–2.344) and were further combined into a group of IST; 2) IST was significantly associated with the lower risk of disease progression and increased odds ratio for remission; 3) the positive effects of IST were limited to cases with proteinuria >2 g/24 h; 4) the likelihood of IgAN remission and progression did not differ significantly between TE+ and TE-, IST-TE+ and IST-TE- groups. There were no cases of disease progression in the IST+TE+ group. The cumulative renal survival was higher in the IST+TE+ group compared to IST+ TE- group (p=0.010), while the probability of remission did not differ.
Conclusion. IST was associated with a lower risk of IgAN progression and increased probability of remission, while these effects of IST were limited to patients with proteinuria >2 g/24 h. TE in combination with IST is associated with an additional reduction in the risk of disease progression.
