Основную группу составили 80 пациентов с подтвержденным диагнозом сахарный диабет 2-го типа, контрольная группа включала 30 практически здоровых добровольцев. Всем исследуемым проведена оптическая когерентная томография (ОКТ) на аппарате RTVue-100 (Optovue, США) и микропериметрия на аппарате MAIA (CenterVue, Италия). Уровень белка S100b, BDNF и NGF в сыворотке крови определяли с помощью специфических реактивов фирмы R&amp;D Diagnostics Inc. (США) методом сэндвич-варианта твердофазного иммуноферментного анализа.</p></sec><sec><title>Результаты</title><p>Результаты. В основной группе уровень белка S100b был достоверно (p = 0,001) выше и составил 56,86 (31,12–104,02) пг/мл в сравнении с контрольной группой 45,19 (37,27–51,79) пг/мл. Анализ уровня мозгового нейротрофического фактора (BDNF) наоборот показал достоверное (p = 0,02) его снижение у представителей основной группы 27,38 (25,15–29,12) пг/мл (в контрольной группе 30,19 (27,38–32,14) пг/мл). Уровень фактора роста нервов (NGF) в основной группе был значимо (p = 0,02) выше 7,53 (5,63–10,54) пг/мл (в контрольной группе 5,96 (4,77–8,13) пг/ мл).</p></sec><sec><title>Заключение</title><p>Заключение. В исследовании выявлен дисбаланс сывороточного уровня исследуемых нейробелков у пациентов с сахарным диабетом 2-го типа и признаками нейродегенерации сетчатки. Выявленные изменения требуют дальнейшего комплексного изучения с целью определения возможности их использования в качестве дополнительных критериев прогнозирования развития нейродегенерации сетчатки у данной категории пациентов. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To evaluate the serum levels of S100b protein, brain-derived neurotrophic factor (BDNF), and nerve growth factor (NGF) in patients with type 2 diabetes mellitus, as well as to establish a correlation between the studied parameters and retinal neurodegeneration.</p></sec><sec><title>Methods</title><p>Methods. In total, 80 patients with confirmed type 2 diabetes (experimental group) and 30 healthy volunteers (control group) were included in the study. All patients were examined using an RTVue-100 optic coherence tomography scanner (Optovue, USA) and a MAIA microperimeter (CenterVue, Italy). The serum levels of S100b, BDNF, and NGF were determined by a sandwich-type solid-phase enzyme immunoassay using reagents produced by R&amp;D Diagnostics Inc. (USA).</p></sec><sec><title>Results</title><p>Results. The serum level of S100b protein was found to be significantly (p = 0.001) higher in the experimental group, comprising 56.86 (31,12–104,02) pg/ml, compared to that in the control group of 45.19 (37.27–51.79) pg/ml. Conversely, the brain-derived neurotrophic factor (BDNF) showed a significant (p = 0.02) decrease to the level of 27.38 (25.15–29.12) pg/ml in the experimental group compared to the level of 30.19 (27.38–32.14) pg/ml in the control group. The serum level of nerve growth factor (NGF) in the experimental group was found to be 7.53 (5.63–10.54) pg/ml, thereby exceeding significantly (p = 0.02) the level of 5.96 (4.77–8.13) pg/ml in the control group.</p></sec><sec><title>Conclusions</title><p>Conclusions. The results obtained indicate an imbalance in the serum levels of the studied neuroproteins in patients with type 2 diabetes mellitus and retinal neurodegeneration signs. The identified variations require further research in order to determine the feasibility of their use as additional criteria for predicting the development of retinal neurodegeneration in such patients. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диабетическая ретинопатия</kwd><kwd>сахарный диабет</kwd><kwd>нейродегенерация</kwd><kwd>белок S100b</kwd><kwd>мозговой нейротрофический фактор</kwd><kwd>фактор роста нервов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diabetic retinopathy</kwd><kwd>diabetes mellitus</kwd><kwd>neurodegeneration</kwd><kwd>S100b protein</kwd><kwd>brain-derived neurotrophic factor</kwd><kwd>nerve growth factor</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">Шестакова М.В., Викулова О.К., Железнякова А.В., Исаков М.А., Дедов И.И.
