The investigation enrolled 47 patients with a verified diagnosis of DPN, who were divided into two groups. Group 1 included 23 patients (10 men and 13 women; mean age, 62.9±7.5 years), Group 2 consisted of 24 patients (9 men and 15 women, mean age, 65.5±7.9 years). All the patients used Berlithione: Group 1 received its intravenous doses of 600 mg for 14 days, then oral ones of 600 mg for other 16 days; Group 2 took oral doses of 600 mg for 30 days. The therapy results were assessed using the digital rating scale (DRS), the Douleur Neuropathique 4 (DN4) neuropathic pain rating scale, and the neurological soft signs (NSS), and electroneuromyography (ENMG) data.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Berlithione was found to have a good tolerability. No adverse reactions were detected in any case; and there was no need to discontinue this drug. On day 21 of therapy, there were statistically significant differences in the indicators of pain intensity on DRS in Group 1 patients (p&lt;0.05), some of them (n=8) had positive clinical changes as a reduction in the severity of hypesthesia. Both groups showed a tendency to improve ENMG parameters as a certain increase in excitation propagation velocity and M-response amplitude; however, these changes did not reach a statistical significance level. At the same time, in 6 out of the 8 patients in Group 1 with positive clinical changes, the described ENMG changes correlated with a reduction in the severity of hypesthesia. There were no significant changes on the NSS scale after 3 weeks of therapy. On day 30 of treatment, both groups were recorded to have statistically significant changes in pain intensity measures versus the baseline values, but no significant inter-group differences.</p></sec><sec><title>Conclusion</title><p>Conclusion. Thus, Berlithione demonstrated its efficacy in both patient groups, but its positive effect occurred 1 week earlier in the step therapy group. It is noted that it is expedient to use this drug long (&gt;1 month) for DPN.</p></sec></abstract><trans-abstract xml:lang="ru"><p>В качестве патогенетической терапии диабетической полиневропатии (ДПН) в нашей стране широко используются препараты α-липоевой кислоты.</p><p>Цель исследования – сравнение эффективности и безопасности применения пероральных и инъекционных форм препарата α-липоевой кислоты при ДПН.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. В исследование было включено 47 больных с верифицированным диагнозом ДПН, которые были разделены на две группы. В 1-ю группу вошли 23 пациента (10 мужчин и 13 женщин, средний возраст – 62,9±7,5 года), во 2-ю – 24 пациента (9 мужчин и 15 женщин, средний возраст – 65,5±7,9 года). Все пациенты получали Берлитион: 1-я группа – внутривенно по 600 мг в течение 14 дней, затем внутрь по 600 мг еще 16 дней; 2-я группа – внутрь по 600 мг в течение 30 дней. Результаты терапии оценивали с помощью цифровой рейтинговой шкалы (ЦРШ), шкалы оценки невропатической боли DN4 и шкалы неврологических симптомов NSS, данных электронейромиографии (ЭНМГ).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Была установлена хорошая переносимость Берлитиона. Ни в одном случае не было выявлено нежелательных реакций и не возникло необходимости в отмене данного препарата. На 21-й день терапии определялись статистически значимые различия по показателям интенсивности боли (ЦРШ) у пациентов 1-й группы (p&lt;0,05), у части из них (n=8) определялась положительная динамика клинических показателей в виде уменьшения выраженности гипестезии. В обеих группах была выявлена тенденция к улучшению параметров ЭНМГ в виде некоторого нарастания скорости распространения возбуждения и амплитуды М-ответов, однако эти изменения не достигали уровня статистически значимых. В то же время у 6 из 8 пациентов 1-й группы с положительной динамикой клинических показателей описанные изменения ЭНМГ коррелировали с уменьшением выраженности гипестезии. Достоверных изменений по шкале NSS через 3 нед терапии выявлено не было. К 30-му дню лечения статистически значимые изменения показателей интенсивности боли по сравнению с первоначальными значениями, но без достоверных межгрупповых различий были зафиксированы в обеих группах.</p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, Берлитион продемонстрировал свою эффективность в обеих группах пациентов, но в группе ступенчатой терапии положительный эффект наступал на 1 нед раньше. Отмечается целесообразность длительного (&gt;1 мес) применения данного препарата при ДПН.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диабетическая полиневропатия</kwd><kwd>болевой синдром</kwd><kwd>сахарный диабет</kwd><kwd>α-липоевая кислота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diabetic polyneuropathy</kwd><kwd>pain syndrome</kwd><kwd>diabetes mellitus</kwd><kwd>α-lipoic acid</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">Левин ОС.
