Прогностические показатели развития ATRA-синдрома при лечении острого промиелоцитарного лейкоза

Прогностические показатели развития ATRA-синдрома при лечении острого промиелоцитарного лейкоза

Abstract

The application of all-trans-retinoic acid (ATRA) in the protocols of treatment of acute promyelocyte leucosis provided the achievement of 95% of full remissions andfast correction of coagulopathy. Besides, ATRA along with positive impact can exert the side effects, among which the most dangerous is the differentiation syndrome. On the basis of analysis of clinical signs, biochemical, hemostasiologic and morphologic blood indicators it is established that among prognostic criteria of differentiation syndrome development are presence of febrile temperature, decrease of content of thrombocytes lesser than 20-109/l (deep degree of thrombocytopenia), prolongation of index of activated partial thromboplastin time relative to norm before treatment start. Apart from this, the following factors also are among such kind of criteria: decrease of hemoglobin after ATRA prescription before differentiation syndrome development, on-going hypofibrinogenemia and deep degree of thrombocytopenia under concurrent increase of content of urea and creatinine as compared with initial values in treatment dynamics.

Использование в протоколах лечения острого промиелоцитарного лейкоза полностью трансретиноевой кислоты (all-trans-retinoic acid ATRA) обеспечило достижение 95% полных ремиссий и быстрой коррекции коагулопатии. Однако наряду с положительным действием ATRA может оказывать побочные эффекты, среди которых наиболее опасен дифференцировочный синдром (ДС). На основании оценки клинических признаков, биохимических, гемостазиологических и морфологических показателей крови установлено, что к прогностическим критериям развития ДС следует отнести наличие фебрильной температуры, снижение количества тромбоцитов менее 20 · 10 9/л (глубокая степень тромбоцитопении), удлинение индекса активированного парциального тромбопластинового времени относительно нормы до начала терапии. Помимо этого таковыми являются: снижение уровня гемоглобина после назначения ATRA перед развитием ДС, продолжающаяся гипофибриногенемия и глубокая степень тромбоцитопении при одновременном нарастании количества мочевины и креатинина по сравнению с исходными величинами в динамике лечения.
