Развитие данного состояния может быть обусловлено рядом факторов, но в педиатрической практике ЛР связывают прежде всего с недоношенностью, течением инфекционного процесса (чаще всего — пневмониями), экстремально низкой массой тела при рождении, приемом определенных препаратов как матерью во время беременности, так и ребенком, хромосомными аномалиями и другими причинами. Особую важность изучению ЛР придает то, что подобные изменения в периферической крови наблюдаются при ряде других заболеваний, в том числе и при течении злокачественных процессов — лейкозов, что требует грамотного подхода к дифференциальной диагностике, привлечения различных специалистов, а также делает ЛР диагнозом исключения.</p></abstract><trans-abstract xml:lang="en"><p>Being a rather rare, but at the same time extremely important finding in the general blood test, the leukemoid reaction (LR) is a short-term sharp increase in the level of leukocytes above 30—50 x 109/l with a shift of the leukocyte formula to the left. The development of this condition may be due to a number of factors, but in pediatric practice, LR is primarily associated with prematurity, the course of the infectious process (most often pneumonia), extremely low body weight, taking certain medications both by the mother during pregnancy and by the child, chromosomal abnormalities and others. Of particular importance to the study of LR is the fact that similar changes in peripheral blood are observed in a number of other diseases, including the course of malignant processes — leukemia, which requires a competent approach to differential diagnosis, the involvement of various specialists and makes LR an exception diagnosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лейкемоидная реакция</kwd><kwd>врожденная пневмония</kwd><kwd>новорожденный</kwd><kwd>гематологические изменения</kwd><kwd>лейкоцитоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>leukemoid reaction</kwd><kwd>congenital pneumonia</kwd><kwd>newborn</kwd><kwd>hematological changes</kwd><kwd>leukocytosis</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">Неонатология: национальное руководство: в 2 т.
