Изучить особенности фармакокинетики цефидерокола у пациента с сепсисом.Материал и методы. Изучали фармакокинетику цефидерокола у пациента, который находился в онкогематологическом стационаре по поводу лечения первичного иммунодефицита — хронической гранулематозной болезни с сопутствующим диагнозом «сепсис», вызванной Burkholderia cepacia. Цефидерокол назначали в трех различных дозах: 3 раза в сутки по 30, 45 и 60 мг/кг. Определение сывороточной концентрации антибиотика проводили методом высокоэффективной жидкостной хроматографии — тандемной масс-спектрометрии (ВЭЖХ-МС/МС) с последующим построением фармакокинетической кривой и расчетом фармакокинетических параметров.Результаты. У исследуемого штамма B. cepacia выявлен высокий уровень устойчивости к стандартно назначаемым антибиотикам. В отношении назначенного цефидерокола укороченный период полувыведения, что, вероятно, могло быть обусловлено повышенными значениями скорости клубочковой фильтрации и массивной инфузионной терапией (3 л/м2 /сут). Полученные значения площади под фармакокинетической кривой AUC = 362,1 мг×ч/л и Cmax = 117,1 мг/л были наиболее близки к данным, приведенным в инструкции (AUC = 394,7 мг×ч/л и Cmax = 138 мг/л) только в случае дозы, равной 60 мг/кг 3 раза в сутки. При этом в случае назначения данной дозы наблюдалось снижение времени сывороточной концентрации ниже четырехкратной минимальной подавляющей концентрации (МПК) (fT &lt; 4 × МПК) до 17,4 % против таковых 39,9 % и 40,2 % при дозировании 30 мг/кг и 45 мг/кг соответственно и увеличении времени сывороточной концентрации (fT &gt; 10 × МПК) до 50,2 % против 11,4 % и 13,4 % соответственно.Заключение. Использование метода ВЭЖХ-МС/МС с целью определения сывороточной концентрации цефидерокола является эффективным подходом к проведению терапевтического лекарственного мониторинга цефидерокола. Его применение может быть полезным инструментом для подбора эффективной и безопасной дозы, что позволяет проводить своевременную коррекцию дозы особенно для пациентов, находящихся в критическом состоянии. </p></abstract><trans-abstract xml:lang="en"><p>Objective. To evaluate the pharmacokinetic features of cefiderocol in a patient with sepsis.Materials and methods. In this research, we studied the pharmacokinetics of cefiderocol in a patient who was admitted to an oncohematology hospital for the treatment of primary immunodeficiency — chronic granulomatous disease with a concomitant diagnosis of sepsis caused by Burkholderia cepacia. Cefiderocol was administered in three different doses: 3 times a day at 30, 45 and 60 mg/kg. The serum concentration of the antibiotic was determined by high-performance liquid chromatography — tandem mass spectrometry (HPLC-MS/MS) with subsequent construction of a pharmacokinetic curve and calculation of pharmacokinetic parameters.Results. The studied B. cepacia strain showed a high level of resistance to standard antibiotics. The prescribed cefiderocol had a shortened half-life, which could probably be due to increased values of the glomerular filtration rate (GFR) and massive infusion therapy (3 l/m2 /day). The obtained values of the area-under-the-time-versus-concentration curve (AUC) AUC = 362.1 mg×h/l and Cmax = 117.1 mg/l were closest to the data given in the instructions (AUC = 394.7 mg×h/l and Cmax = 138 mg/l) only in the case of the prescribed dose of 60 mg/kg 3 times a day. Moreover, in the case of prescribing this dose, a decrease in the time of serum concentration below four times the minimum inhibitory concentration (MIC) (fT &lt; 4 × MIC) was observed — 17.4 %, against 39.9 % and 40.2 % at a dose of 30 mg/kg and 45 mg/kg and an increase in the time of serum concentration above (fT &gt; 10 × MIC) — 50.2 %, against 11.4 % and 13.4 %.Conclusion. The use of HPLC-MS/MS to determine the serum concentration of cefiderocol is an effective approach to therapeutic drug monitoring of cefiderocol. Its use can be a useful tool for selecting an effective and safe dose, which allows for timely dose adjustments, especially for critically ill patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цефидерокол</kwd><kwd>терапевтический лекарственный мониторинг</kwd><kwd>сепсис</kwd><kwd>онкогематология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cefiderocol</kwd><kwd>therapeutic drug monitoring</kwd><kwd>sepsis</kwd><kwd>oncohematology</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">Результаты аллогенной трансплантации гемопоэтических стволовых клеток у пациентов с хронической гранулематозной болезнью в Российской детской клинической больнице / Е.
