ПАЦИЕНТЫ И МЕТОДЫ. В поперечно-срезовое по дизайну исследование был включен 71 пациент нефрологических отделений, которым выполнялась диагностическая нефробиопсия. По результатам световой, электронной микроскопии, иммунофлюоресцентного исследования у 23 (32,4%) пациентов выявлена IgA-нефропатия (мезангиально-пролиферативный гломерулонефрит), у 14 (19,7%) – фокально-сегментарный гломерулосклероз, у 22 (31,0%) – мембранозная нефропатия, у 12 (16,9%) – болезнь минимальных изменений. Помимо стандартных лабораторных и инструментальных методик, произведена оценка уровня цистатина-С, NGAL в сыворотке крови, цистатина-С, NGAL, нефрина – в суточной моче. Степень выраженности гломерулосклероза, тубулоинтерстициального склероза, атрофии канальцев оценивались количественно и полуколичественно. РЕЗУЛЬТАТЫ. Скорость клубочковой фильтрации (СКФ), определенная по цистатину-С сыворотки крови, наиболее точно отражала выраженность гломерулосклероза. NGAL сыворотки крови коррелировал с СКФ по цистатину-С и уровнем нефринурии. Уровень NGAL мочи был связан с выраженностью атрофии канальцев; экскреция NGAL и цистатина-С с мочой достигла максимальных значений у пациентов с высокой протеинурией. ЗАКЛЮЧЕНИЕ. Для оценки выраженности гломерулосклероза у пациентов с первичной гломерулярной патологией предпочтительно использование определение СКФ по цистатину-С. Выраженность атрофии канальцев наиболее точно отражает экскреция NGAL с мочой. NGAL сыворотки характеризует начальные этапы повреждения клеток клубочка. Экскреция NGAL и цистатина-С с мочой зависит от протеинурии, что ограничивает их использование в диагностике острого повреждения почек (ОПП) у пациентов с гломерулярной патологией и высокой протеинурией.</p></abstract><trans-abstract xml:lang="en"><p>THE AIM: assessment of relationship between level of biomarkers and clinical and pathomorphological signs of glomerular, tubular sclerosis and tubular atrophy in patients with primary glomerular disease. PATIENTS AND METHODS. In cross-section study 71 patients hospitalized in department of nephrology with performed renal biopsies were included. According the results of light and electron microscopy 23 (32.4%) patients had IgA-nephropathy (mesangial proliferative glomerulonephritis), 14 (19.7%) – focal segmental glomerulosclerosis, 22 (31.0%) – membranous nephropathy, 12 (16,9%) – minimal change disease. Besides standard laboratory and instrumental investigations the level of serum cystatin-C and NGAL, urine cystatin-С, NGAL, nephrin were mesaured. Glomerulosclerosis, tubulointerstitial sclerosis and tubular atrophy were estimated quantitatively and semi quantitatively. RESULTS. GFR estimated using cystatin-C most accurately reflects the degree of glomerular sclerosis. Serum NGAL correlated with GFR estimated using cystatin-C and level of nephrinuria. Urine NGAL and tubular atrophy correlated as well; the rates of urine NGAL and cystatin-C excretion were the highest in patients with high range proteinuria. CONCLUSION. The applying of GFR estimated using cystatin-C is preferable in assessment of glomerulosclerosis degree. Urine NGAL excretion most accurately shows the severity of tubular atrophy while serum NGAL reflects the earliest stages of glomerular cell injury. Urine excretion of NGAL and cystatin-C depends on proteinuria and this fact should limit their exploitation in acute kidney injury diagnostics in patients with primary glomerulopathies and high range of proteinuria.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биомаркеры</kwd><kwd>цистатин-С</kwd><kwd>NGAL</kwd><kwd>нефрин</kwd><kwd>гломерулонефрит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biomarker</kwd><kwd>cystatin-C</kwd><kwd>NGAL</kwd><kwd>nephrin</kwd><kwd>glomerulonephritis</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">Смирнов АВ, Каюков ИГ, Добронравов АВ, Кучер АГ.
