Группу сравнения составили 13 детей с нейродеге-неративными заболеваниями (2-я группа). В контрольную группу вошли 29 здоровых детей аналогичного возраста. Средний уровень коэнзима Qlo в 1-й группе детей (0,56+0,06 мкмоль/л) не отличался от значений контрольной группы. Однако у этих пациентов бьио значительно снижено отношение коэнзим (310/холестерин (0,10+0,01; /КО,001). У больных старшей возрастной подгруппы определялся достоверно более низкий уровень коэнзима Qlo, что, по-видимому, отражает прогрессирующий характер патологии. Отмечена тенденция к снижению с возрастом отношения коэнзим (310/холестерин. У детей 2-й группы выявлено более высокое содержание коэнзима Qlo в крови (1,53+0,23 мкмоль/л; /КО,001), чем в 1-й группе, и повышение отношения коэнзим (310/холестерин (0,31+0,04 мкмоль/л; /КО,001). Рекомендуется продолжить исследования для установления обоснованности использования низких показателей коэнзима как дополнительного критерия дифференциальной диагностики митохондриальных болезней.</p></abstract><trans-abstract xml:lang="en"><p>То establish the diagnostic value of a change in the indicator coenzyme Qlo, its blood levels were tested in 15 children with mitochondrial diseases (Group 1). A comparison group consisted of 13 children with neurodegenerative diseases (Group 2). A control group included 29 healthy children of the same age. In Group 1 patients, the mean coenzyme Qlo level (0,56+0,06 mcmol/1) did not differ from that in the control group. However, these patients had a considerably lower coenzyme Q10/cholesterol ratio (0,10+0,01; /K0,001). The patients in the older age subgroup were found to have a significantly lower coenzyme Qlo level, which seems to reflect the progressive nature of the abnormality. There was a trend for the coenzyme Q10/cholesterol ratio to decline with age. Group 2 children had higher blood coenzyme Qlo levels (1,53+0,23; /K0,001) than Group 1 and an increased Q10/cholesterol ratio (0,31+0,04; /K0,001). It is advisable to continue the investigation to provide a rationale for using low coenzyme values as an additional criterion for the differential diagnosis of mitochondrial diseases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>митохондриальные болезни</kwd><kwd>нейродегенеративные болезни</kwd><kwd>коэнзим Qw холестерин</kwd><kwd>диагностика.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>mitochondrial diseases</kwd><kwd>neurodegenerative diseases</kwd><kwd>coenzyme Qw</kwd><kwd>cholesterol</kwd><kwd>diagnosis.</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">Goldstein А.С., Bhatia P., Vento J.M.
