Thirty-five patients aged 9 months to 53 years (mean age, 14.5 years) with different inherited forms of SMA were examined. Clinical, genealogical, and laboratory tests were carried out. A control group consisted of 40 healthy individuals aged 7–45 years (mean age, 16.5 years). The levels of neurotrophins, such as brain-derived growth factor (BDGF), nerve growth factor (NGF), and ciliary neurotrophic factor (CNTF) in serum samples were determined by enzyme immunoassay.</p></sec><sec><title>Results</title><p>Results. Changes in the expression of the neurotrophic factors were found in patients with SMA. The enzyme immunoassay data suggest that the serum concentrations of BDGF, NGF, and CNTF in patients with SMA were significantly higher than those in healthy controls. The group of SMA patients aged under 18 years showed a statistically significant (p&lt;0.001) increase in NGF concentrations (3680±936 ng/ml) versus the control group of the same age (625±444 pg/ml).</p></sec><sec><title>Conclusion</title><p>Conclusion. In our opinion, the clinical polymorphism of SMA can be explained by the polymorphism of various pathogenic factors: genetic, morphofunctional, and biochemical ones. Overexpression of neurotrophins was first noticed to play a role in the development of more severe clinical types of SMA (proximal SMA), which may be related to both the ontogenetic features of children's age and disease duration. The study results can be further used to choose pathogenetic personalized therapy for SMA.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Цель исследования – клинико-лабораторное изучение спинальной мышечной атрофии (СМА) для уточнения особенностей патогенеза и роли нейротрофических факторов в формировании полиморфизма данного заболевания.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. Обследовано 35 больных с различными наследственными формами СМА в возрасте от 9 мес и до 53 лет (средний возраст – 14,5 года). Проводилось клиническое, генеалогическое и лабораторное исследование. Контрольную группу составили 40 здоровых (7–45 лет, средний возраст – 16,5 года). Определение уровня нейротрофинов: фактора роста головного мозга (ФРГМ), фактора роста нерва (ФРН) и цилиарного нейротрофического фактора (ЦНТФ) проводили иммуноферментным методом в образцах сыворотки крови.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлены изменения экспрессии нейротрофических факторов у больных СМА. Данные иммуноферментного анализа свидетельствуют о том, что концентрация ФРГМ, ФРН и ЦНТФ в сыворотке крови у больных СМА статистически значимо выше, чем у здоровых. В группе больных СМА младше 18 лет отмечено статистически значимое (p&lt;0,001) повышение концентрации ФРН (3680±936 пг/мл) в сравнении с лицами контрольной группы (625±444 пг/мл) того же возраста.</p></sec><sec><title>Заключение</title><p>Заключение. Клинический полиморфизм СМА, по нашему мнению, можно объяснить полиморфизмом различных патогенетических факторов: генетических, морфофункциональных, биохимических. Впервые отмечена роль гиперэкспрессии нейротрофинов в развитии более тяжелых клинических типов СМА (проксимальная СМА), что может быть связано как с онтогенетическими особенностями детского возраста, так и с длительностью заболевания. Результаты исследования в дальнейшем могут быть использованы для подбора патогенетической персонифицированной терапии СМА.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>cпинальная мышечная атрофия</kwd><kwd>полиморфизм</kwd><kwd>нейротрофины</kwd><kwd>иммуноферментный метод</kwd><kwd>сыворотка крови</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spinal muscular atrophy</kwd><kwd>polymorphism</kwd><kwd>neurotrophins</kwd><kwd>enzyme immunoassay</kwd><kwd>serum</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">Гусев ЕИ, редактор.
