IgA-нефропатия (IgAN) – самая распространенная гломерулопатия, приводящая к хронической болезни почек (ХБП) и терминальной почечной недостаточности. Среди новых подходов к лечению ХБП в последнюю декаду прочно закрепились ингибиторы натрий-глюкозного котранспортера 2 типа, в том числе дапаглифлозин. Однако анализ эффективности дапаглифлозина при IgAN выполняли лишь в двух исследованиях, имевших ряд ограничений. Целью нашего исследования был анализ эффектов дапаглифлозина у пациентов с IgAN в реальной нефрологической практике.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В ретроспективное исследование были включены пациенты с IgAN (n=30), проходившие обследование в клинике НИИ нефрологии ПСПбГМУ имени академика И. П. Павлова в 2022 г. Критериями включения были: первичная IgAN; расчетная скорость клубочковой фильтрации (рСКФ) ≥25 мл/мин/1,73 м² в начале наблюдения; период наблюдения ≥6 месяцев (мес); отсутствие сахарного диабета. Пациенты были разделены на группы: терапия дапаглифлозином 10 мг/сут (Дапа+, n=19) и без таковой (Дапа-, n=11). Оценивали стандартные клинико-демографические показатели, включая суточную протеинурию (СП) и рСКФ на момент нефробиопсии и 6, 12, 18 и 24 месяцев наблюдения. Морфологический анализ включал оценку по оксфордской классификации MEST-C, согласно которой тубулярную атрофию/интерстициальный фиброз (Т) оценивали полуколичественно: Т0, T1 и Т2 – вовлечение &lt;25 %, 25–50 % и &gt;50 % кортикальной зоны соответственно.</p></sec><sec><title>Результаты</title><p>Результаты. Группы Дапа+ и Дапа- были сопоставимы по основным клинико-морфологическим характеристикам. Снижение СП в группе Дапа+ было достоверно выше, чем в группе Дапа- на 12 мес (M (IQR): -1,14 [-2,04;-0,31] vs -0,5 [-1,26;+0,34] г/сут, p=0,042), 18 мес (M (IQR): -1,09 [-1,98;-0,4] vs -0,84 [-2,4;+0,73] г/сут, p=0,042), и 24 мес (M (IQR): -1,34 [-1,68;-0,86] vs -0.78 [-1,02;+0,32] г/сут, p=0,021).</p><p>Разницы в изменении рСКФ между исследуемыми группами выявлено не было. Снижение СП у пациентов с T&lt;2 в группе Дапа+ было достоверно выше, чем в Дапа- на момент наблюдения 6 мес (M (IQR): -0,94 [-1,21;-0,58] vs -0,58 [-0,58;-1,13] г/сут, p=0,042), 12 мес (M (IQR): -0,77 [-1,14;-0,31] vs -0,5 [-0,5;+0,34] г/сут, p=0,042) и 24 мес (M (IQR): -0,86 [-1,34;-0,3] vs -0,32 [-1,02;+0,32], г/сут, p=0,042), а динамика рСКФ не отличалась.</p></sec><sec><title>Заключение</title><p>Заключение. При IgAN дапаглифлозин обладает нефропротективным эффектом, в том числе у пациентов с умеренным тубулоинтерстициальным фиброзом. Это подчеркивает важность назначения этого препарата на ранних стадиях ХБП с целью замедления прогрессирования заболевания.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. IgA-nephropathy (IGAN) is the most common glomerulopathy worldwide leading to chronic kidney disease (CKD) progression and end stage renal disease. In the last decade sodium-glucose cotransporter type 2 inhibitors (iSGLT2) including dapagliflozin are considered to be the excellent  option for CKD treatment. However, the efficacy of dapagliflozin in patients with IgAN was analyzed only in few studies which had some serious limitations. We conducted the present study to reveal the effects of the drug in the real clinical practice.</p></sec><sec><title>Methods</title><p>Methods. In this retrospective study we enrolled patients with IGAN (n=30) who were diagnosed and treated in nephrology clinic of Pavlov University during 2022. Inclusion criteria were: primary variant of IgAN, eGFR≥25 ml/min/1.73 m² at the time of the diagnosis, follow-up period ≥6 months (mo) from the time of diagnosis/ dapagliflozin initiation, absence of diabetes mellitus. Patients were divided on 2 groups: on dapagliflozin treatment 10 mg/day (Dapa+, n=19) and without iSGLT2 therapy (Dapa-, n=11). In all patients we evaluated basic clinical and demographic parameters including 24h proteinuria and eGFR at the time of kidney biopsy and at 6, 12, 18 and 24 mo of follow-up. All tissue samples were classified by MEST-C (Oxford classification). Tubular atrophy/ interstitial fibrosis was estimated semiquantitatively as T0, T1 and T2 corresponding to &lt; 25%, 25-50% and &gt;50% of cortex involved, respectively.</p></sec><sec><title>Results</title><p>Results. Basic clinical and morphological parameters were compared between Dapa+ and Dapa-. Reduction of 24h-proteinuria in Dapa+ was greater than in Dapa- at 12 mo (M (IQR): -1.14 [-2.04;-0.31] vs -0.5 [-1.26;+0.34] g/day, p=0,042), 18 mo (M (IQR): -1.09 [-1.98;-0.4] vs -0.84 [-2.4;+0.73] g/day, p=0,042), and 24 mo (M (IQR): -1.34 [-1.68;-0.86] vs -0.78 [-1.02;+0.32] g/day, p=0,021). There was no difference in eGFR changes between two groups. In patients with T&lt;2 decrease in 24h-proteinuria in Dapa+ was better than in Dapa- at 6 mo (M (IQR): -0.94 [-1.21;-0.58] vs -0.58 [-0.58;-1.13] g/day, p=0,042), 12 mo (M (IQR): -0.77 [-1.14;-0.31] vs -0.5 [-0.5;+0.34] g/day, p=0,042) and 24 mo (M (IQR): -0.86 [-1.34;-0.3] vs -0.32 [-1.02;+0.32], g/day, p=0,042).</p></sec><sec><title>Conclusion</title><p>Conclusion. Dapagliflozin showed the distinct nephroprotective effect in patients with IgAN including those who had mild-moderate tubulointerstitial fibrosis. This finding supports the idea to initiate the iSGLT2 treatment in early CKD stages aiming to achieve better proteinuria reduction and slow CKD progression.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нефропротекция</kwd><kwd>ингибиторы SGLT2</kwd><kwd>хроническая болезнь почек</kwd><kwd>атрофия канальцев</kwd><kwd>интерстициальный фиброз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nephroprotection</kwd><kwd>SGLT2 inhibitors</kwd><kwd>chronic kidney disease</kwd><kwd>tubular atrophy</kwd><kwd>interstitial fibrosis</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">KDIGO 2021 Clinical Practice Guideline for the Management of Glomerular Diseases // Kidney International. 2021.
