Ребёнок был госпитализирован на 30-е сутки жизни. При поступлении отмечались жалобы на иктеричность кожного покрова, малую прибавку массы тела, судорожный синдром (в анамнезе). Дифференциальный диагноз проводился между нарушениями функции печени на фоне воспалительного процесса; различными формами патологии печени и желчных путей наследственного характер; врождёнными пороками развития желчевыводящих путей; метаболическими и гормональными нарушениями.</p></sec><sec><title>Результаты</title><p>Результаты. В биохимическом анализе крови установлено повышение уровней трансаминаз, щелочной фосфатазы, общего и прямого билирубина, гипогликемия, увеличение содержания пролактина, тиреотропного гормона, уменьшение концентраций T4 свободного, инсулина, полное отсутствие кортизола. При магнитно-резонансной томографии (МРТ) головного мозга определена картина субэпендимальных узлов гетеротопии серого вещества и эктопия нейрогипофиза.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. Уменьшение содержания глюкозы в крови в сочетании с синдромом холестаза могут быть ранним, но не специфическим признаком врождённого гипопитуитаризма. Гипогликемия у новорождённых возникает в результате внутриутробной недостаточности соматотропного гормона и кортизола, относящихся к контринсулярным гормонам. Дефицит кортизола в этих условиях способствует формированию холестаза путём снижения экспрессии канальцевых транспортных белков, регулирующих секрецию желчи в желчные канальцы. При анализе гормонального профиля для верификации диагноза необходимо проведение МРТ головного мозга. Для пациентов с врождённым гипопитуитаризмом характерными признаками являются картина «пустого» или «частично пустого» турецкого седла, а также классическая триада: гипоплазия/аплазия ножки гипофиза, эктопия нейрогипофиза, гипоплазия аденогипофиза.</p><p>Представленный клинический случай свидетельствует, что синдром холестаза может быть дебютом тяжёлой эндокринной патологии. Ранняя диагностика и адекватно подобранная заместительная гормональная терапия приводят к быстрому купированию жизнеугрожающих состояний и улучшению качества жизни ребёнка.</p></sec><sec><title>Участие авторов</title><p>Участие авторов: Харитонова Н.А. — концепция и дизайн исследования, статистическая обработка; Харитонова Н.А., Евлоева Х.С. — сбор и обработка материала, написание текста; Харитонова Н.А., Басаргина М.А. — редактирование.

The child was hospitalized on the 30th day of his life. At admission, complaints were noted about the ictericity of the skin, low body weight gain, convulsive syndrome (history). Differential diagnosis was carried out between diseases such as: impaired liver function, against the background of the course of the infectious-inflammatory process; diseases of the liver and bile ducts of hereditary nature; congenital malformations of the bile tract; metabolic and hormonal disorders.</p></sec><sec><title>Results</title><p>Results. During the survey, the following deviations from the norm were obtained: in the biochemical analysis there was an increase in the level of transaminases, alkaline phosphatase, total and direct bilirubin, hypoglycemia. When evaluating the hormonal profile, an increase in the level of prolactin, thyroid hormone, a decrease in the level of T4 free, insulin, and a complete absence of cortisol were revealed. Magnetic resonance imaging (MRI) of the brain — a picture of subependymal nodes of gray matter heterotopia, ectopia of the neurophysis.</p></sec><sec><title>Conclusions</title><p>Conclusions. Lowering glucose levels, especially when combined with cholestasis syndrome, may be an early but nonspecific sign of congenital hypopituitarism. Hypoglycemia in newborns occurs as a result of intrauterine insufficiency of somatotropic hormone and cortisol related to contrinsular hormones. Cortisol deficiency also contributes to the development of cholestasis syndrome by reducing the expression of tubule transport proteins that regulate bile secretion into bile tubules. In addition to studying the hormonal profile, a brain MRI is performed to verify the diagnosis. Patients with congenital hypopituitarism are characterized by the detection of characteristic signs: the picture of the “empty” or “partially empty” Turkish saddle, as well as the classic triad of symptoms: hypoplasia/pituitary leg aplasia, neurophysis ectopia, adenohypophysis hypoplasia.</p><p>This clinical case demonstrates that cholestasis syndrome may lie in the debut of a more severe pathology. At the same time, early diagnosis and adequately selected hormone replacement therapy leads to a rapid cessation of life-threatening conditions and an improvement in the quality of life of the child.</p></sec><sec><title>Contribution</title><p>Contribution: Kharitonova N.A. — concept and design of the study, statistical processing; Kharitonova N.A., Evloeva Kh.S. — collection and processing of material, writing the text; Kharitonova N.A., Basargina M.A. — editing.
