Согласно рекомендациям, процедуру колоноскопии оптимально начинать в интервале от 2 до 4 часов с момента окончания приема слабительного средства. Одноэтапный прием всей дозы малообъемного раствора полиэтиленгликоля (ПЭГ) утром перед колоноскопией может быть более предпочтителен для пациентов по сравнению с двухэтапной схемой подготовки, предполагающей наличие ночного перерыва между вечерним и утренним приемом разделенной дозы препарата. ЦЕЛЬ. Сравнить эффективность, безопасность и переносимость одноэтапной утренней и двухэтапной (сплит) схем приема раствора ПЭГ с аскорбиновой кислотой (ПЭГ + Аск) 2 л для подготовки к колоноскопии. МЕТОДЫ. Выполнено многоцентровое, проспективное, простое слепое (для эндоскописта), рандомизированное исследование не меньшей эффективности одноэтапной утренней схемы приема раствора препарата ПЭГ + Аск 2 л (МОВИПРЕП®) по сравнению с двухэтапной, разделенной на вечернюю и утреннюю дозы, схемой приема того же препарата с целью подготовки к колоноскопии. Первичной конечной точкой была успешная очистка толстой кишки; при этом «успехом» считались категории A и B чистоты согласно шкале Хэрфилд (Harefield). Клинически значимый предел не меньшей эффективности был выбран -15 % с односторонним 5 %-м уровнем значимости. Вторичными конечными точками были общая удовлетворенность/переносимость процедуры подготовки к колоноскопии участниками исследования, комплаенс пациентов и безопасность исследуемого препарата. РЕЗУЛЬТАТЫ. Всего в исследовании участвовали 140 пациентов из 6 центров, рандомизированных по 70 человек в две группы. При анализе популяции в соответствии с назначенным вмешательством (ITT) успешная очистка толстой кишки достигалась у 94,3 % пациентов, принимавших исследуемый препарат по утренней схеме, и у 91,4 % пациентов, использовавших сплит схему. Нижняя граница одностороннего 95 % ДИ для разницы эффектов составила - 9,7% при выбранном пределе -15 % (p&lt;0,001 для не меньшей эффективности). При этом у 71,4 % пациентов обеих групп достигалась наивысшая категория А чистоты кишки по шкале Хэрфилд. Первое опорожнение кишечника после приема первого литра исследуемого препарата у пациентов в группе утренней схемы приема наступало быстрее, чем в группе сплит схемы: медиана времени составила, соответственно, 1,08 и 1,58 ч (р&lt;0,001). Почти все пациенты в группе утренней схемы (69/70) и в группе сплит схемы (67/70) приняли исследуемый препарат, как планировалось. В целом, прием ПЭГ + Аск 2 л хорошо переносился пациентами обеих групп. Нежелательные явления возникали у 58,6 и 61,4 % пациентов при использовании утренней и сплит схем приема исследуемого препарата, соответственно. Наиболее часто регистрируемыми явлениями были типичные желудочно-кишечные расстройства (53,5 % пациентов) и изменения в лабораторных тестах (12,1 % пациентов). Серьезных нежелательных явлений не отмечалось. ВЫВОД. Одноэтапная утренняя схема приема раствора препарата ПЭГ + Аск 2 л не уступает двухэтапной (сплит) схеме приема данного препарата в эффективности, является безопасной и удобной для пациентов при подготовке к колоноскопии.</p></abstract><trans-abstract xml:lang="en"><p>BACKGROUND. According to guidelines the optimal delay between the last dose of purgative and colonoscopy is no longer than 2-4 hours. Morning-only dosing of polyethyleneglycol solution (PEG) prior to colonoscopy versus standard split-dosing with nocturnal pause may be more acceptable for patient. AIM. To compare the efficacy, safety and tolerability of morning-only dosing regimen of 2 liter PEG plus ascorbic acid solution (PEG + Asc) 2 L to split-dose PEG + Asc 2 L for bowel preparation prior to colonoscopy. METHODS. This was a multicenter prospective endoscopist-blinded randomized non-inferiority study comparing morning-only to split dosing with nocturnal pause regimen of PEG + Asc 2 L (MOVIPREP®) for the bowel preparation prior to colonoscopy. The primary endpoint was successful colon cleansing where «Success» represented grades of bowel cleansing А and В according to Harefield Cleansing Scale© (HCS©). Clinically relevant non-inferiority margin was set at -15 % with one-sided significance level of 5 %. Secondary endpoints were general satisfaction/acceptability ofpatients with the preparationfor colonoscopy, as well as patient compliance and safety of the study drug. RESULTS. Overall 140 patients from 6 centers were enrolled in the study and randomized into two groups of 70 each. ITT analysis showed successful colon cleansing in 94,3 % in the morning-only group versus 91,4 % in the split-dose group. An estimated treatment difference was 2,9 %, 95 % lower confidence limit for the difference -9,7 % with the prespecified non-inferiority margin -15 % (p for non-inferiority &lt;0.001). Furthermore 71,4 % ofpatients had the highest grade A colon cleansing according to HCS© in each group. In patients in the morning-only intake group, the time to first bowel motion following the first liter of PEG + Asc 2 L was shorter, with a median time of 1.08 hours, compared with 1.58 hours in the split-dose group (p&lt;0,001). Nearly all of the patients treated in the morning-only dosing group (69/70) and in the split-dose group (67/70) received the study medication as planned. In general, the study drug was well tolerated in patients of both groups. At least one treatment-emergent adverse event was reported by 58,6 % of patients in the morning-only dosing group and by 61,4 % of patients in the split dosing group. The most frequently reported adverse events were typical gastrointestinal disorders (53,5 % of patients) and changes in laboratory tests (12,1 % of patients). No serious adverse events were reported in this study. CONCLUSION. Morning-only dosing regimen of PEG + Asc 2 L is non-inferior to split-dosing regimen in terms of colon cleansing and is safe and convenient for use as a bowel preparation prior to colonoscopy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>подготовка к колоноскопии</kwd><kwd>малообъёмный раствор ПЭГ</kwd><kwd>раствор аскорбиновой кислоты</kwd><kwd>сплит-доза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colonoscopy preparation</kwd><kwd>low volume PEG</kwd><kwd>ascorbic acid solution</kwd><kwd>split-dosing</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">Bernstein, C.
