In spite of significant advances in medical care, neonatal sepsis remains an important risk factor for neonatal morbidity and mortality. Accordingly, the present study was conducted to compare the number of nucleated red blood cells per 100 white blood cells (NRBC/100WBC) in neonates with early onset sepsis and non-infectious neonates. <italic>Materials and methods</italic>. In this cross-sectional study of 154 neonates admitted to the NICU of Ghaem Hospital in Mashhad, Iran within the first three days of life, during 2014 to 2018, the characteristics of 44 neonates identified early onset sepsis (Case group) were compared with 110 non-infectious neonates (Control group). After the confirmation of sepsis in neonates based on positive blood culture and laboratory results, a researcher-made questionnaire containing neonatal characteristics (gestational age, weight, first minute Apgar scores, fifth minute Apgar score, duration of oxygen therapy, and mechanical ventilation duration) and neonatal laboratory profiles (routine blood culture, WBC, NRBC/100WBC, CRP, blood glucose, calcium and venous blood gas) was filled in. <italic>Results.</italic> The results of this study showed that the absolute number of NRBC/mm<sup>3</sup> in control group was 56.07±86.65 and in case group was 592.70±1166.75 (p = 0.000). Also, the number of NRBC per 100 white blood cells in control group was 6.54±11.18 and in case group was 31.84±40.07 (p = 0.000). The absolute number of NRBC/mm<sup>3</sup> for the detection of early onset sepsis had a good sensitivity (78%) and NRBC/100WBC was suitable specificity (68.2%). <italic>Conclusion</italic>. This study indicated that NRBC/100 WBC and absolute NRBC count/mm<sup>3</sup> can be helpful in the diagnosis of early onset sepsis and have an acceptable sensitivity and specificity.</p></abstract><trans-abstract xml:lang="ru"><p><italic>Введение</italic>. Несмотря на значительный прогресс в области оказания медицинской помощи, неонатальный сепсис остается важным фактором риска неонатальной заболеваемости и смертности. Настоящее исследование было проведено для сравнения величин отношения ядросодержащих эритроцитов к 100 лейкоцитам (NRBC/100WBC) у недоношенных новорожденных с ранним началом сепсиса и без инфекционной патологии. <italic>Материалы и методы</italic>. В поперечное исследование было включено 154 новорожденных, поступивших в отделение интенсивной терапии больницы Гаем в Мешхеде, Иран, в течение первых трех дней жизни в период с 2014 по 2018 г. У 44 новорожденных обнаружены признаки раннего сепсиса (группа сепсиса), 110 новорожденными не имели инфекционной патологии (контрольная группа). После подтверждения сепсиса на основании положительных результатов посева крови и лабораторных исследований, проанализировали составленный нами вопросник, содержащий характеристики новорожденных (гестационный возраст, вес, оценка по шкале Апгар на первой минуте, оценка по шкале Апгар на пятой минуте, продолжительность кислородной терапии и продолжительность искусственной вентиляции легких) и неонатальные лабораторные профили (образцы пуповинной крови, общий анализ крови, абсолютное количество ядросодержащих эритроцитов в мм<sup>3</sup> (NRBC/мм<sup>3</sup>), отношение количества ядросодержащих эритроцитов к 100 лейкоцитам (NRBC/100WBC), С-реактивный белок). <italic>Результаты</italic> исследования показали, что абсолютное количество NRBC в контрольной группе составляло 56,07±86,65/мм<sup>3</sup>, а в группе сепсиса — 592,70±1166,75/мм<sup>3</sup> (p = 0,000). Кроме того, количество NRBC на 100 лейкоцитов в контрольной группе составляло 6,54±11,18, а в группе сепсиса — 31,84±40,07 (p = 0,000). Метод определения абсолютного количества NRBC/мм<sup>3</sup> показал хорошую чувствительность (78%), а подсчет соотношения NRBC/100WBC — неплохую специфичность (68,2%) для выявления раннего начала сепсиса. <italic>Заключение</italic>. Отношение NRBC/100WBC и абсолютное количество NRBC/мм<sup>3</sup> могут быть полезны в диагностике сепсиса у недоношенных новорожденных и демонстрируют приемлемую чувствительность и специфичность.</p></trans-abstract><kwd-group xml:lang="en"><kwd>early onset sepsis</kwd><kwd>nucleated red blood cells (NRBC)</kwd><kwd>neonates</kwd><kwd>blood culture</kwd><kwd>infection</kwd><kwd>prematurity</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ранний сепсис</kwd><kwd>ядросодержащие эритроциты (NRBC)</kwd><kwd>новорожденные</kwd><kwd>гемокультура</kwd><kwd>инфекция</kwd><kwd>недоношенность</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
