Оценка клинического значения выявления циркулирующих антител к подоцитарному трансмембранному рецептору секретируемой фосфолипазы А2 M-типа (анти-PLA2 R АТ) у больных с первичной МН на фоне проводимой терапии. ПАЦИЕНТЫ И МЕТОДЫ: в обсервационное исследование были включены 20 подтвержденных и проспективно наблюдаемых случаев первичной мембранозной нефропатии на фоне симптоматического лечения в сочетании или без сочетания с иммуносупрессией. Регистровали клинические данные на момент проведения биопсии почки и в процессе проспективного наблюдения: пол, возраст, концентрации креатинина и альбумина сыворотки крови, суточную протеинурию (СПБ), АД, расчетную скорость клубочковой фильтрации. Медиана периода проспективного наблюдения составила 525 (265–1030) дней. Анти-PLA2 R АТ класса IgG определяли после проведенного лечения методом непрямой иммунофлюоресценции. РЕЗУЛЬТАТЫ: анти-PLA2 R АТ были выявлены у 7 больных (группа 1) и отсутствовали у 13 из 20 обследованных больных (группа 2). На момент проведения биопсии почки группы не отличались по уровню протеинурии, альбуминемии, АД и функции почек. На фоне лечения в группе 1 не было зафиксировано существенного изменения уровня протеинурии, альбуминемии и случаев ремиссии заболевания; в группе 2 СПБ снизилась в несколько раз по сравнению с исходной, уровень альбумина сыворотки крови практически нормализовался, у всех больных констатировано достижение ремиссии заболевания (3 случая – частичной, 10 случаев – полной). Все случаи полной ремиссии были достигнуты на фоне комбинированной терапии кортикостероидами и циклоспорином. ЗАКЛЮЧЕНИЕ: отсутствие циркулирующих анти-PLA2 R АТ на фоне проводимой терапии связано с достижением клинической ремиссии первичной МН; этот тест может быть использован для мониторинга активности заболевания, оценки эффективности терапии и прогноза.</p></abstract><trans-abstract xml:lang="en"><p>AIM OF THE STUDY: evaluation of clinical significance of circulating antibodies to transmembrane phospholipase A2 M-type receptor of podocytes (anti-PLA2R Ab) in patients with primary membranous nephropathy (MN) on the top of already administered therapy. PATIENTS AND METHODS. 20 proved or prospectively observed patients with primary membranous nephropathy on symptomatic treatment with or without immunosuppressive therapy were included into observational study. Clinical data obtained at the moment of biopsy and during prospective follow-up included: gender, age, serum creatinine and albumin concentration, daily proteinuria (DP), AP, estimated glomerular filtration rate. Median of prospective follow-up was 525 (265- 1030) days. Anti-PLA2R Ab of IgG class was detected after treatment by indirect immunofluorescence. RESULTS. Anti-PLA2R Ab was found in 7 patients (group 1) and was absent in 13 (group 2) of 20 patients studied. There were no differences in level of proteinuria, albuminemia, AP and renal function at the time of biopsy. There were no significant changes in level of proteinemia, albuminemia and cases of clinical remissions in group 1 during treatment; in group 2 DP decreased significantly in contrast to initial value, serum albumin level practically normalized and clinical remission was achieved in all patients (3 cases – partial, 10 cases – complete). All cases of complete remission were observed after corticosteroids and cyclosporine combined therapy. CONCLUSION. Absence of anti-PLA2R Ab in patients on therapy is associated with achievement of clinical remission of primary MN; this test can be applied for monitoring of the disease activity, evaluation of treatment efficacy and prognosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мембранозная нефропатия</kwd><kwd>лечение</kwd><kwd>антитела</kwd><kwd>рецептор фосфолипазы А2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>membranous nephropathy</kwd><kwd>treatment</kwd><kwd>antibodies</kwd><kwd>phospholipase A2 receptor</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">Beck LH Jr, Bonegio RG, Lambeau G. et al.
