Дефицит пируватдегидрогеназного комплекса (ДПДГ) – одно из немногих митохондриальных заболеваний, имеющее патогенетическую терапию в виде кетодиеты и дотации тиамина. Мы представляем опыт «НМИЦ им. В.А.Алмазова», где наблюдаются 7 пациентов с ДПГД. Кетодиета была введена в 6 случаях, один ребенок с неонатальным лакататацидозом умер до потановки диагноза. В двух случаях кетодиета была начата парентерально в отделении реанимации, в трех случаях – стационарно в течение недели и в одном случае − в течение месяца амбулаторно. Во всех случаях был достигнут целевой уровень кетонов крови, купирован лакатат-ацидоз. У двоих детей с неонатальным лактат-ацидозом состояние было стабилизировано, дети были выписаны домой, в одном случае ребенок начал развиваться, в то время как у второго психомоторное развитие отсутствовало, появились судороги. У девочки с энцефалопатией на фоне рефрактерной эпилепсии после введения кетодиеты отмечается улучшение неврологического статуса, но сохраняются приступы. Три девочки наблюдались с диагнозом ДЦП, в этих случаях отмечается наилучший ответ на терапию, две девочки начали ходить. Целевой уровень кетонов был достигнут при различном кетосоотношении и различной доле среднецепочечных триглицеридов в питании. Кетодиета является эффективным методом лечения при ДПДГ. Наилучший результат достигается при раннем начале терапии и при более легком клиническом фенотипе.</p></abstract><trans-abstract xml:lang="en"><p>Mitochondrial diseases are a heterogeneous group with a progressive course and a high probability of lethal outcome. Pyruvate dehydrogenase complex deficiency (PDHd) is one of the few mitochondrial diseases with pathogenetic therapy in the form of ketodiet and thiamine supplementation. We present the experience of the Almazov National Research Medical Center, where 7 patients with PDHd are observed. The ketodiet was administered in 6 cases; one child with neonatal lactic acidosis died before diagnosis. Two children started the diet parenterally in the ICU, three were inpatient for a week, and one was outpatient for a month. Target blood ketone and lactate levels were achieved in all cases. Two children with neonatal lactic acidosis were stabilized and discharged. One showed developmental progress while the other had no psychomotor development and developed seizures. A girl with epileptic encephalopathy improved neurologically with the diet, but seizures persisted. Three girls with cerebral palsy had the best therapeutic response, two began walking. The target ketone level was achieved with different keto ratios and different proportions of medium-chain triglycerides in the diet. Ketodiet is an effective treatment method for PDHd. The best result is achieved with early initiation of therapy and with a milder clinical phenotype.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дефицит пируватдегидрогеназного комплекса</kwd><kwd>митохондриальные заболевания</kwd><kwd>кетогенная диета</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pyruvate dehydrogenase complex deficiency</kwd><kwd>mitochondrial diseases</kwd><kwd>ketogenic diet</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">Rahman S.
