Время начала и тяжесть клинических проявлений при болезни гемоглобина M зависит от того, какую цепь глобина затронула генетическая мутация.</p><sec><title>Цель исследования</title><p>Цель исследования. Представить случай врожденной метгемоглобинемии, связанный с болезнью гемоглобина М, не распознанный в неонатальном периоде, обобщить данные по диагностике, терапии и прогноз при данной патологии.</p></sec><sec><title>Клиническое наблюдение</title><p>Клиническое наблюдение. У доношенного ребенка без органной патологии отмечено развитие диффузного цианоза в раннем неонатальном периоде, снижение pSO2 до 70%, резистентное к терапии кислородом, нарастающая анемия. Уровень метгемоглобина максимально до 17%. Снижение уровня метгемоглобина до 5,7% и стабилизация pSO2 &gt;90% получены после двух трансфузий эритроцитарной взвеси. При электрофорезе на 5-е сутки жизни патологических форм гемоглобина не выявлено. При повторном электрофорезе в возрасте 5 мес выявлена патологическая фракция гемоглобина 8,9%, соответствующая гемоглобину M Iwate. В течение первого года наблюдения рост и развитие ребенка соответствует возрастной норме; отмечается стабильный акроцианоз. Метгемоглобин в крови сохраняется на уровне 8,7–8,9% без специфической терапии в течение последних 6 мес.</p></sec><sec><title>Заключение</title><p>Заключение. Диагностическими критериями диагноза врожденной метгемоглобинемии, вызванной дефектным гемоглобином M (M-гемоглобинопатия), явились высокий стойкий уровень метгемоглобина (9–12%) и выявленный аномальный вариант гемоглобина M при электрофорезе (HbM Iwate).</p></sec></abstract><trans-abstract xml:lang="en"><p>Congenital methemoglobinemia, especially caused by pathological hemoglobin M, is an extremely rare cause of cyanosis in newborns. The time to onset and severity of clinical manifestations in hemoglobin M disease depends on which globin chain the mutation occurred in.</p><sec><title>Purpose</title><p>Purpose. To present the case of congenital methemoglobinemia associated with hemoglobin M disease, not recognized in the neonatal period, to summarize the data on diagnosis, therapy, and prognosis for this pathology.</p></sec><sec><title>Clinical case</title><p>Clinical case. In a full-term child without organ pathology, the development of diffuse cyanosis in the early neonatal period, a decrease in pSO2 of 70%, resistant to oxygen therapy, and increasing anemia were noted. The level of methemoglobin is up to a maximum of 17%. A decrease in the level of methemoglobin to 5.7% and stabilization of pSO2 &gt;90% were obtained after two transfusions of erythrocyte suspension. No pathological forms of hemoglobin were detected during electrophoresis on the 5th day of life. Repeated electrophoresis at the age of 5 months revealed a pathological hemoglobin fraction of 8.9% corresponding to hemoglobin M Iwate. During the first year of observation, the growth and development of the child corresponds to the age norm. Stable acrocyanosis. Methemoglobin in the blood remains at the level of 8.7–8.9% without specific therapy for the last 6 months.</p></sec><sec><title>Conclusion</title><p>Conclusion. The diagnosis of congenital methemoglobinemia due to the presence of defective hemoglobin M (M-hemoglobinopathy) was established basing on the high persistent level of methemoglobin (9–12%) and hemoglobin electrophoresis identified an abnormal hemoglobin M (HbM Iwate) variant.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>новорожденный</kwd><kwd>врожденная метгемоглобинемия</kwd><kwd>цитохром b5 редуктаза</kwd><kwd>гемоглобин М</kwd><kwd>цианоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>newborn</kwd><kwd>congenital methemoglobinemia</kwd><kwd>cytochrome b5 reductase</kwd><kwd>hemoglobin M</kwd><kwd>cyanosis</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">Iolascon A., Bianchi P., Andolfo I., Russo R., Barcellini W., Fermo E., et al.; SWG of red cell and iron of EHA and EuroBloodNet.
