В письме представлен развернутый ответ на вопрос о границе низко- и высокопоточных диализаторах в связи с практикой организации диализа в системе ОМС. Быстрый прогресс в создании новых диализных мембран и разработке технологий не всегда находит быстрое отражение в нормативных документах и клинических рекомендациях. Принято считать нижней границей параметров высокопоточных диализаторов коэффициент просеивания для β2-микроглобулина свыше 0,6 или клиренс по β2-микроглобулина более 20 мл/мин. Однако для современных высокопоточных диализаторов коэффициент ультрафильтрации утратил значение, а коэффициент просеивания по β2-микроглобулину, приблизившись к единице, перестал разграничивать типы диализаторов. Сужение ширины распределения размеров пор мембраны позволило приблизить границу проницаемости вплотную к альбумину, ограничив одновременно его потери.</p></abstract><trans-abstract xml:lang="en"><p>The letter provides a detailed answer to the question about the boundary between low and high flux dialyzers in the practice of organizing dialysis in the CHI system. Rapid progress in the development of new dialysis membranes and technologies is not always quickly reflected in regulatory documents and clinical guidelines. It is generally accepted to consider the sieving coefficient for β2-microglobulin more than 0.6 or clearance for β2-microglobulin more than 20 ml/min as the lower limit of the parameters of high-flux dialyzers. However, for modern high-flux dialyzers, the ultrafiltration coefficient has lost its value, and the sieving coefficient for β2-microglobulin, having approached one, has ceased to distinguish between the types of dialyzers. Narrowing the width of the membrane pore size distribution made it possible to bring the permeability boundary close to albumin, simultaneously limiting its loss.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Строков А.Г., Гуревич К.Я., Ильин А.П. и соавт.
