Проведено катамнестическое исследование с оценкой особенностей дебюта, течения, лечения стероидочувствительного в дебюте, стероидозависимого НС у 47 детей (31 мальчик, 66 % и 16 девочек, 34 %). У 34 (72,3 %) из 47 детей со стероидозависимым НС выявлены клинические проявления аллергии, у 13 (27,7 %) не выявлено клинических проявлений аллергии. В сравнительном исследовании оценена эффективность терапии циклоспорином у 15 детей и микофенолатом натрия у 27 детей, имеющих клинические проявления аллергии, по сохранению ремиссии НС в течение 6, 12, 24 мес после отмены препарата. Определена медиана длительности ремиссии НС в течение 2 лет после отмены иммуносупрессивной терапии. Из 27 детей 8 (29,6 %) получали микофенолат натрия после терапии циклоспорином и вошли в обе группы. </p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Установлены статистически значимые различия в длительности ремиссии НС в течение 6, 12, 24 мес после терапии микофенолатом натрия и циклоспорином у детей, имеющих клинические проявления аллергии. Ремиссия НС в течение 6 мес после отмены терапии микофенолатом натрия сохранялась в 81,5 % (у 22 из 27 пациентов) в отличие от таковой после терапии циклоспорином – в 40,0 % (у 6 из 15 пациентов) у детей, имеющих клинические проявления аллергии (р&lt;0,05). Ремиссия НС в течение 12 мес после отмены терапии микофенолатом натрия сохранялась в 55,6 % (у 15 из 27 пациентов) в отличие от таковой после терапии циклоспорином – в 13,3 % (у 2 из 15 пациентов) у детей, имеющих клинические проявления аллергии (р&lt;0,05). Ремиссия НС в течение 24 мес после отмены терапии микофенолатом натрия сохранялась в 37 % (у 10 из 27 пациентов) в отличие от таковой после терапии циклоспорином – в 6,7 % (у 1 из 15 пациентов) у детей, имеющих клинические проявления аллергии (р&lt;0,05). Медиана длительности ремиссии НС в течение 2 лет у детей, имеющих клинические проявления аллергии, после отмены терапии циклоспорином и микофенолата натрия составила 7,0 [2,0–11,0] и 17,0 [6,0–24,0] мес соответственно (р&lt;0,05).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ.

Ремиссия стероидозависимого НС у детей, имеющих клинические проявления аллергии, в течение 12 мес после отмены терапии микофенолатом натрия или циклоспорином сохранялась в 55,6 и 13,3 % соответственно.

Follow-up study with analysis of onset, clinical course and treatment includes 47 children ((31 boys (66 %) и 16 girls (34 %)) with steroid-dependent NS, 34 (72,3 %) had clinical manifestation of allergy, 13 (27,7 %) didn’t have clinical manifestation of allergy. The efficiency of therapy with cyclosporine in 16 patients and mycophenolate sodium in 27 patients with clinical manifestation of allergy is estimated in comparative study by analysis of 6, 12, 24 month remission rate after treatment.
