Материалы и методы: в исследование включались стабильные пациенты ГД с длительностью заместительной почечной терапии (ЗПТ) не менее 3 месяцев. Лабораторные исследования выполнялись до второго на неделе сеанса ГД, в начале, через 3 месяца и через год после начала исследования. Корректировка значений бикарбоната (Bi) диализного раствора выполнялась постепенно, не более чем на 1 ммоль/л в месяц. Целевым уровнем Bi крови через 3 месяца коррекции являлся 22-25 ммоль/л. Когортный анализ выживаемости и относительного риска смерти был выполнен через 3 года от начала исследования. Результаты: в исследование были выключены 146 пациентов ГД, средний возраст 60±11 лет, продолжительность ЗПТ 63±53 месяца. Значение Bi диализного раствора от исходного 31±1 к месяцу 3 было увеличено до 33±1 ммоль/л и до 34±1 через год (p&lt;0,001); Bi крови увеличился от исходных значений к месяцу 3 и через год: 20,5±1,8→21,5±1,9→22,8±2,4 ммоль/л, p&lt;0,001. Пациенты с неосложненным коморбидным фоном (Индекс коморбидности Чарлсон, ИКЧ&lt;6 баллов) характеризовались более высоким уровнем Bi крови после коррекции, чем больные с большим числом осложнений (ИКЧ≥6 баллов): 22,6±1,8 v. 21,7±1,9 ммоль/л, p=0,021. На фоне коррекции ацидоза наблюдалось достоверное снижение выраженности гиперфосфатемии: 1,98±0,46→1,73±0,56→ 1,72±0,5 ммоль/л от исходных значений к месяцу 3 и по истечению года, соответственно (p&lt;0,001); увеличение альбумина сыворотки через год от начала исследования (с 37,7±2,1 до 40,3±3,1 г/л, p&lt;0,001). При анализе выживаемости в скорректированной на основные факторы риска регрессионной модели, когорта пациентов с низким уровнем Bi крови после коррекции (≤20 ммоль/л) имела относительный риск смерти (ОР) в 6,98 раз больше (95%ДИ ОР 2,22÷21,9), чем когорта нормального уровня Bi (≥22,0 ммоль/л), p=0,001. Выводы: индивидуальный подбор уровня бикарбоната диализного раствора у пациентов ГД способствует снижению тяжести ацидоза, выраженности гиперфосфатемии и тенденцией к увеличению альбумина сыворотки. В долгосрочной перспективе коррекция ацидоза приводит к снижению летальности. Пациенты с осложненным коморбидным фоном в меньшей степени отвечают на коррекцию ацидоза, что требует дальнейшего изучения проблемы коррекции кислотно-основных нарушений в данной группе.</p></abstract><trans-abstract xml:lang="en"><p>Aim: to evaluate the efficacy and safety of individual correction of metabolic acidosis in hemodialysis (HD) patients. Method: the study included HD patients with the duration of renal replacement therapy (RRT) of at least 3 months. Laboratory tests were performed before the second HD session of the week, at baseline, 3 months and 1 year after the study start. We adjusted the dialysate bicarbonate (Bi) gradually, no more than 1 mmol/l per month. The target blood Bi level after 3 months of correction was 22-25 mmol/l. A cohort survival and relative risk of death analysis performed 3 years after the start of the study. Results: 146 HD patients with average age 60±11 years and average RRT duration 63±53 months were included to the study. The dialysate Bi increased from the baseline 31±1 to 33±1 at month 3 and to 34±1 mmol/l at one year (p&lt;0.001) of HD; blood Bi level increased from the baseline to month 3 and after 1 year: 20.5±1.8→21.5±1.9→22.8±2.4 mmol/l, p&lt;0.001. Patients with low comorbidity (Charlson comorbidity index, CCI&lt;6 points) were characterized by a higher level of blood Bi after correction in comparison with patients with a large number of complications (CCI≥6 points): 22.6±1.8 v. 21.7±1.9 mmol/l, p=0.021. Against the background of the acidosis correction there was a significant decrease in the hyperphosphatemia severity: 1.98±0.46→1.73±0.56→1.72±0.5 mmol/l from baseline values to month 3 and after 1 year, respectively (p&lt;0.001), serum albumin increased one year after the beginning of the study (from 37.7±2.1 to 40.3±3.1 g/l, p&lt;0.001). Patients with low blood Bi levels after correction (≤20 mmol/l) had increased risk of all-cause mortality (HR 6.98; 95%CI 2.22÷21.9) compared with those with normal level of Bi (≥22.0 mmol/l), p=0.001. Conclusion: individualization of the dialysate bicarbonate level in HD patients contributes to a reduction in the acidosis severity and decrease in the serum phosphate level as well as increase in serum albumin. In the long term, correction of acidosis leads to a mortality reduction. Patients with a complicated comorbidity are characterized by a worse response to the acidosis correction and this requires further search for effective methods of individual acid-base disorders correction of in this group.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кислотно-основное равновесие</kwd><kwd>гемодиализ</kwd><kwd>коморбидность</kwd><kwd>выживаемость</kwd><kwd>гиперфосфатемия</kwd><kwd>acid-base balance</kwd><kwd>hemodialysis</kwd><kwd>comorbidity</kwd><kwd>survival</kwd><kwd>hyperphosphatemia</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">Lyon D.M., Dunlop D.M., Stewart C.P.
