Оценка диагностической ценности индексов эритроцитов и содержания гемоглобина в ретикулоцитах для установления дефицита железа у доношенных детей первого года жизни.</p><p>Характеристика детей и методы исследования. Проведено проспективное когортное диагностическое обследование здоровых доношенных детей в возрасте 6 и 12 мес в детских поликлиниках Самары и Тольятти. Лабораторное обследование включало общий анализ крови с определением концентрации гемоглобина, числа эритроцитов, эритроцитарных индексов и эквивалента содержания гемоглобина в ретикулоцитах (Ret-He); определение содержания ферритина в сыворотке и С-реактивного белка. Диагностическую ценность количественных показателей определяли по величине AUC (area under the curve). Из анализа исключены дети с анемией без дефицита железа и дети, получавшие препараты железа в течение 1 мес, предшествующего лабораторному обследованию.</p></sec><sec><title>Результаты</title><p>Результаты. В анализ включены 207 детей. При диагностике дефицита железа у детей наибольшая AUC обнаружена у показателя Ret-He: 0,747 [0,679; 0,816] в возрасте 6 мес и 0,790 [0,708; 0,871] в 12 мес. При железодефицитной анемии диагностическая ценность Ret-He была выше: AUC 0,826 [0,754; 0,898] в возрасте 6 мес и 0,865 [0,809; 0,920] в 12 мес.</p></sec><sec><title>Выводы</title><p>Выводы. Показатель Ret-He продемонстрировал большую диагностическую ценность в скрининге дефицита железа у детей первого года жизни по сравнению с индексами эритроцитов. Диагностическая ценность индексов эритроцитов и Ret-He в отношении железодефицитной анемии выше, чем при железодефицитных состояниях.</p></sec></abstract><trans-abstract xml:lang="en"><p>Diagnostics of Iron deficiency anemia (IDA) in outpatient pediatric practice is often based on decreased hemoglobin level.

To study the diagnostic value of red blood cell indices and reticulocyte hemoglobin equivalent in diagnostics of iron deficiency in full-term infants.</p><p>Children characteristics and research methods. A prospective cohort study of healthy full-term children aged from 6 to 12 months at the children hospitals of Samara and Tolyatti. The laboratory examination included a general blood test to determine the concentration of hemoglobin, the number of red blood cells, red blood cell indices, and reticulocyte hemoglobin equivalent (Ret-He); to determine serum ferritin and C-reactive protein. The AUC (area under the curve) was used to determine the diagnostic value of quantitative indicators. The children with anemia without iron deficiency and children who received iron supplements within 1 month prior to laboratory examination were excluded from the analysis.</p></sec><sec><title>Results</title><p>Results. The study involved 207 children. When diagnosing iron deficiency in children, the highest AUC was found in Ret-He: 0.747 [0.679; 0.816] in 6-months-old children and 0.790 [0.708; 0.871] in 1-year-old children. The Ret-He diagnostic value was higher in children with iron deficiency: AUC 0.826 [0.754; 0.898] in 6- months-old children and 0.865 [0.809; 0.920] in 1-year-old children.</p></sec><sec><title>Conclusion</title><p>Conclusion. Ret-He is a better predictor of iron deficiency in children under 1 year as compared to the red blood cell indices. The diagnostic value of red blood cell indices and Ret-He is higher in case of iron deficiency anemia than in case of iron deficiency conditions.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>диагностика</kwd><kwd>железодефицитная анемия</kwd><kwd>железодефицит</kwd><kwd>ретикулоцитарный гемоглобиновый эквивалент</kwd><kwd>показатели эритроцитов</kwd><kwd>ферритин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>diagnostics</kwd><kwd>iron deficiency anemia</kwd><kwd>iron deficiency</kwd><kwd>reticulocyte hemoglobin equivalent</kwd><kwd>erythrocyte indices</kwd><kwd>ferritin</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">Nutritional anaemias: tools for effective prevention and control.
