Поиск надежных методов оценки активности АНЦА-СВ остается актуальным. Среди показателей активации нейтрофильного звена, появившихся в клинической практике, выделяют уровень сывороточного кальпротектина (КЛП), который может быть маркером для мониторинга активности васкулита и выявления пациентов с риском рецидива заболевания. Цель исследования – оценить уровень сывороточного КЛП у пациентов с АНЦА-СВ. Материал и методы. В исследуемую группу включено 64 пациента (37 – с гранулематозом с полиангиитом, 11 – с эозинофильным гранулематозом с полиангиитом и 16 – с микроскопическим полиангиитом) в возрасте 18 лет и старше с достоверным диагнозом АНЦА-СВ. Контрольную группу составили 30 здоровых лиц. Для определения активности АНЦА-СВ использовали индекс BVAS; высокая активность соответствовала значению BVAS &gt;3. Повреждение оценивали с помощью индекса VDI. В зависимости от активности АНЦА-СВ больные были разделены на две группы: с высокой (1-я группа, n=33) и низкой (2-я группа, n=31) активностью. Кроме общепринятых показателей, у всех пациентов с АНЦА-СВ и здоровых доноров исследовали уровень сывороточного КЛП. Результаты и обсуждение. Были выявлены статистически значимые различия (p&lt;0,001) концентрации КЛП у пациентов с АНЦА-СВ в 1-й и 2-й группах. Отмечена значимая корреляция уровня КЛП с количеством лейкоцитов, нейтрофилов, отношением нейтрофилов к лимфоцитам (NLR), системным индексом воспаления (SII). Содержание КЛП в крови при AНЦА-СВ было связано с уровнем креатинина и не ассоциировалось со скоростью клубочковой фильтрации и мочевым осадком. Хотя уровень КЛП зависел от активности заболевания, он не коррелировал с острофазовыми показателями, включая СОЭ и концентрацию СРБ. Заключение. Уровень сывороточного КЛП значимо выше у пациентов с активным АНЦА-СВ и связан с индексами воспаления NLR и SII, что позволяет рассматривать возможность использования данного показателя для оценки активности заболевания.</p></abstract><trans-abstract xml:lang="en"><p>Antineutrophil cytoplasmic antibody-associated systemic vasculitis (ANCA-SV) is a group of rare and potentially severe systemic diseases. The search for reliable methods to assess ANCA-SV activity remains relevant. Among the indicators of neutrophil activation that have emerged in clinical practice, the level of serum calprotectin (CLP) stands out, which can be a marker for monitoring vasculitis activity and identifying patients at risk of disease relapse. Objective: to determine serum CLP levels in patients with ANCA-SV. Material and methods. The study group comprised 64 patients (37 with granulomatosis with polyangiitis, 11 with eosinophilic granulomatosis with polyangiitis and 16 with microscopic polyangiitis) aged 18 years and older with a confirmed diagnosis of ANCA-SV. The control group consisted of 30 healthy individuals. ANCA-SV activity was determined using the BVAS index; high activity corresponded to a BVAS value of &gt;3. Damage was assessed using the VDI index. Depending on ANCA-SV activity, patients were divided into two groups: high activity group (group 1, n=33) and low activity group (group 2, n=31). In addition to the generally accepted indicators, serum CLP levels were assessed in all patients with ANCA-SV and healthy donors. Results and discussion. Statistically significant differences (p&lt;0.001) were found in CLP levels in patients with ANCA-SV in groups 1 and 2. A significant correlation was found between CLP concentration and leukocyte count, neutrophil count, neutrophil-to-lymphocyte ratio (NLR) and systemic inflammatory index (SII). Blood CLP levels in ANCA-SV were associated with creatinine levels and not with glomerular filtration rate and urinary sediment. Although CLP concentration depended on disease activity, it did not correlate with acute phase indicators, including ESR and CRP concentration. Conclusion. Serum CLP concentration is significantly higher in patients with active ANCA-SV and is related to NLR and SII inflammatory indices, so we consider the possibility of using this indicator to assess disease activity. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>васкулит</kwd><kwd>ассоциированный с антинейтрофильными цитоплазматическими антителами</kwd><kwd>активность</kwd><kwd>кальпротектин</kwd><kwd>маркеры воспаления</kwd><kwd>нейтрофилы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vasculitis associated with antineutrophil cytoplasmic antibodies</kwd><kwd>activity</kwd><kwd>calprotectin</kwd><kwd>inflammatory markers</kwd><kwd>neutrophils</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках фундаментальной научной темы № 122040400024-7.</funding-statement><funding-statement xml:lang="en">The article has been conducted within basic scientific topic № 122040400024-7.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kitching AR, Anders HJ, Basu N, et al.
