В исследование включено 159 больных подагрой, не получавших уратснижающие препараты, у которых сывороточный уровень МК составлял &gt;360 мкмоль/л. Пациенты были разделены на две группы: с СКФ &gt;60 мл/мин/1,73 м2 (n=123) и СКФ 30–60 мл/мин/1,73 м2 (n=36). Всем пациентам назначался фебуксостат в дозе 80 мг/сут; если целевой уровень МК в сыворотке не был достигнут, дозу препарата увеличивали до 120 мг/сут. Период наблюдения составлял не менее 6 мес (26 нед).</p><p>До начала и после окончания наблюдения выполняли клинический анализ крови, определение сывороточного уровня глюкозы, креатинина, МК, трансаминаз, креатинфосфокиназы. СКФ рассчитывали по формуле CKD-EPI.</p><p>В двух группах пациентов анализировали изменения сывороточного уровня МК, вероятность достижения целевого уровня МК в крови (&lt;360 мкмоль/л) на фоне терапии фебуксостатом и необходимую для этого дозу препарата.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Изучены данные 152 пациентов, завершивших исследование: 34 из 36 с СКФ 30–60 мл/мин/1,73 м2 и 118 из 123 с СКФ &gt;60 мл/мин/1,73 м2. За время наблюдения достигли целевого уровня МК в сыворотке крови 129 (84,9%) из 152 пациентов: 101 (85,6%) из 118 с СКФ &gt;60 мл/мин/1,73 м2 и 28 (82,4%) из 34 с СКФ 30–60 мл/мин/1,73 м2 (p=0,6). При СКФ &gt;60 мл/мин/1,73 м2 для достижения целевого уровня МК 68 (67,3%) пациентам было достаточно дозы фебуксостата 80 мг/сут и 33 (32,7%) – 120 мг/сут, а при СКФ 30–60 мл/мин/1,73 м2 такие дозы потребовались соответственно 13 (46,4%) и 15 (53,6%) пациентам (р=0,04). Доза препарата, назначаемая в соответствии с титрованием до достижения целевого уровня МК, в группе с СКФ &gt;60 мл/мин/1,73 м2 была статистически значимо меньше (93,1±18,9 мг/сут), чем в группе с СКФ 30–60 мл/мин/1,73 м2 (101,4±20,3 мг/сут), р=0,04.</p></sec><sec><title>Заключение</title><p>Заключение. Эффективность фебуксостата не уменьшается у пациентов с подагрой и умеренным снижением функции почек, достижение у них целевого уровня МК возможно более чем в 80% случаев, но сопряжено с необходимостью применения максимальных суточных доз препарата.</p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><p>Febuxostat (FS) is the drug of choice in impaired renal function, but the dosage regimen and the actual efficacy of the maximum allowable doses required to achieve the target uric acid (UA) level in patients with impaired renal function have not been adequately studied.</p><sec><title>Objective</title><p>Objective: to compare the dosage of FS required to achieve the target level of UA in blood serum in patients with gout with normal or near normal (glomerular filtration rate (GFR) &gt;60 ml/min/1.73 m2) and moderately impaired (GFR 30–60 ml/min/1.73 m2) renal function.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 159 patients with gout who were not receiving urate-lowering medication and had serum UA levels above 360 μmol/l. The patients were divided into two groups: with GFR &gt;60 ml/min/1.73 m2 (n=123) and GFR 30–60 ml/min/1.73 m2 (n=36). All patients were prescribed FS at a dose of 80 mg/day. If the target serum level of UA was not reached, the dose of the drug was increased to 120 mg/day. The observation period was at least 6 months (26 weeks).</p><p>Before the start and after the end of the observation period, complete blood count (CBC), serum levels of glucose, creatinine, UA, transaminases and creatine phosphokinase were assessed. GFR was calculated according to CKD-EPI formula. In two groups of patients, changes in UA serum levels, the probability of reaching the target UA level in the blood (&lt;360 μmol/l) against the background of FS therapy and the dose of the drug required for this were analyzed.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Data from 152 patients who completed the study were analyzed: 34 of 36 patients with GFR 30–60 ml/min/1.73 m2 and 118 of 123 with GFR &gt;60 ml/min/1.73 m2. During the observation period, 129 (84.9%) of 152 patients reached the target level of serum UA: 101 (85.6%) of 118 patients with GFR &gt;60 ml/min/1.73 m2 and 28 (82.4%) of 34 with GFR 30–60 ml/min/1.73 m2 (p=0.6). In the GFR &gt;60 ml/min/1.73 m2 group in 68 (67.3%) patients FS dose of 80 mg/day was enough to achieve the target level of UA and in 33 (32.7%) the dose of 120 mg/day was requires, and for the GFR 30–60 ml/min/1.73 m2 group such doses were required in 13 (46.4%) and 15 (53.6%) patients, respectively (p=0.04). The dose of the prescribed drug after the adjustment until the target level of UA was reached was statistically lower in patients with GFR &gt;60 ml/min/1.73 m2 (93.1±18.9 mg/day) than in the group of patients with GFR 30–60 ml/min/1.73 m2 (101.4±20.3 mg/day), p=0.04.</p></sec><sec><title>Conclusion</title><p>Conclusion. The efficacy of FS does not decline in patients with gout and moderate decline in renal function. In more than 80% of cases it is possible to achieve the target level of UA in these patients, but it is associated with the need to use the maximum daily doses of the drug.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>подагра</kwd><kwd>фебуксостат</kwd><kwd>хроническая болезнь почек</kwd><kwd>скорость клубочковой фильтрации</kwd><kwd>мочевая кислота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gout</kwd><kwd>febuxostat</kwd><kwd>chronic kidney disease</kwd><kwd>glomerular filtration rate</kwd><kwd>uric acid</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках фундаментальной научной темы «Разработка подходов к фенотипированию аутовоспалительных дегенеративных ревматических заболеваний на основе сравнительного изучения биохимических, иммунологических и генетических факторов, связанных с состоянием костной, хрящевой, мышечной и жировой тканей» № 125020501433-4</funding-statement><funding-statement xml:lang="en">The work was carried out as a part of the basic research project on topic “Development of approaches for phenotyping of autoinflammatory degenerative rheumatic diseases on the basis of comparative study of biochemical, immunological and genetic factors associated with bone, cartilage, muscle and adipose tissue condition” №125020501433-4</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Насонова ВА, Барскова ВГ.
