Поскольку данные об оксидативном статусе при СКВ и ВН носят разрозненный характер, целью исследования явилось его комплексное изучение с помощью новых методик. </p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Изучить особенности оксидативного статуса у больных СКВ с поражением почек. </p></sec><sec><title>ПАЦИЕНТЫ И МЕТОДЫ</title><p>ПАЦИЕНТЫ И МЕТОДЫ. В проспективное исследование были включены 53 больных СКВ, из них 40 – с различной выраженностью поражения почек, группа контроля из 87 здоровых доноров. Исследовали показатели: антиоксидантную активность (АОА) плазмы крови, удельную спонтанную активность нейтрофилов, удельную стимулированную активность (пиковую и интегральную), коэффициент затухания респираторного взрыва нейтрофилов, отражающий скорость снижения продукции свободных радикалов после их стимуляции, чем выше этот показатель, тем медленнее снижение продукции свободных радикалов. </p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Показано повышение показателей: радикал-продуцирующей активности нейтрофилов, АОА плазмы крови у больных ВН по сравнению с группой контроля. Повышению АОА плазмы способствовала иммуносупрессивная терапия глюкокортикостероидами (ГКС) и цитостатиками (ЦС) по сравнению с монотерапией ГКС. Выявлена взаимосвязь нарушения оксидативного статуса с выраженностью воспалительных реакций: обнаружена корреляция коэффициента затухания респираторного взрыва с СОЭ. У больных ВН с НС отмечено снижение удельной спонтанной активности нейтрофила, возможно, связанное с истощением их функции при высокой активности заболевания. </p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. Показано повышение показателей активности нейтрофилов, что может быть причиной оксидативного стресса при СКВ с ВН. Оправдано изучение данных показателей на выборках большего объема для поиска мишеней воздействия на нейтрофилы. Представляется сомнительной необходимость антиоксидантной терапии у больных СКВ в связи со значительным повышением АОА плазмы крови, возможно связанным с компенсаторной реакцией организма на оксидативный стресс, а также с терапией ГКС и ЦС.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND. Oxidative status impairment plays a significant role in the pathogenesis of SLE and lupus nephritis (LN). The data about oxidative status in this disease are incomplete, that’s why it’s necessary to use a new approach to study it. </p></sec><sec><title>THE AIM</title><p>THE AIM: To study oxidative status in SLE patients with kidney involvement. </p></sec><sec><title>PATIENTS AND METHODS</title><p>PATIENTS AND METHODS:53 patients with SLE were included in this prospective study, among them 40 patients with different severity of kidney involvement, control group were 87 healthy donors. Oxidative stress parameters were measured: antioxidant activity (AOA) of blood plasma and parameters, characterizing the state of the main source of reactive oxygen species (ROS) – neutrophils, more specifically: specific spontaneous neutrophil activity, specific stimulated activity (peak and integral), coefficient of respiratory burst attenuation, representing the rate of free radical production decrease after stimulation, the higher the value of this parameter, the slower is free radical production decrease. </p></sec><sec><title>RESULTS</title><p>RESULTS. It was shown elevation of neutrophil free radical-producing activity parameters and elevation of blood plasma AOA in patients with LN, comparing to healthy controls. Immunosuppressive therapy with glucocorticosteroids (GCS) and cytostatics (CS) increased blood plasma AOA comparing to monotherapy with GCS. A correlation between oxidative status impairment and intensity of inflammatory reactions was found: correlation of respiratory burst attenuation coefficient with blood sedimentation rate was shown. Reduction of spontaneous free radical-producing neutrophil activity was found in LN patients with NS, which might be the result of neutrophil functional activity attenuation in high disease activity. </p></sec><sec><title>CONCLUSION</title><p>CONCLUSION. The increased free radical-producing neutrophil activity was shown, which might be the cause of oxidative stress in SLE with LN. It seems warranted investigation of these parameters in samples of larger volume to search targets aimed at neutrophils. The necessity of antioxidant therapy in patients with SLE seems doubtful, as they show significant increase of blood plasma AOA, which might result from compensatory reaction of human organism to oxidative stress and therapy with GCS and CS.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>оксидативный стресс</kwd><kwd>системная красная волчанка</kwd><kwd>волчаночный нефрит</kwd><kwd>нейтрофилы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oxidative stress</kwd><kwd>systemic lupus erythematosus</kwd><kwd>lupus nephritis</kwd><kwd>neutrophils</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">Hakkim A, Furnrohr B et al.
