Среди многочисленных причин ГГС особое место занимает артифициальный ГГС как один из вариантов синдрома Мюнхгаузена. Гипогликемия в таких случаях достигается намеренным введением сахароснижающих лекарственных средств. Наиболее часто используются производные сульфонилмочевины, которые являются доступными, недорогими и легальными медикаментами. Ключевую роль в диагностике артифициального ГГС играет тесное сотрудничество клиницистов с лабораторной службой. Так как результаты биохимического и гормонального анализов на фоне гипогликемии при приеме пероральных сахароснижающих препаратов и панкреатогенном ГГС идентичны, проведение дифференциальной диагностики данных состояний возможно только при обнаружении субстанций секретагогов инсулина в крови (или моче).</p><p>В России исследование пероральных сахароснижающих лекарственных препаратов при подозрении на их артифициальный прием не внедрено. Артифициальный ГГС, как правило, является диагнозом исключения, и его подтверждение зачастую основано на обнаружении медикаментов среди личных вещей больного, что представляет значительную сложность с учетом норм этики. Однако с 2018 г. в нашем центре при помощи метода высокоэффективной жидкостной хроматографии с тандемной масс-спектрометрией (ВЭЖХ-МС/МС) проводится исследование субстанций 7 пероральных сахароснижающих препаратов в крови пациентов с гиперинсулинемическим ГГС: глибенкламида, гликвидона, гликлазида, глимепирида, глипизида, натеглинида и репаглинида. В данной статье представлен клинический случай приема пациентом без сахарного диабета глибенклами- да и детектирование данного препарата с помощью ВЭЖХ-МС/МС.</p></abstract><trans-abstract xml:lang="en"><p>Hypoglycemic syndrome (HGS) is a significant decrease glucose in blood, manifested by neurological symptoms, and stopped by the introduction of glucose. Among the many causes of HGS the special place is taken by the factitious hypoglycemia, as one of the variants of Munchausen syndrome. Hypoglycemia in such cases is achieved by the intentional introduction of hypoglycemic drugs. The most commonly used medications are sulfonylurea derivatives, which are affordable, inexpensive and legal. The close collaboration of clinicians with the laboratory service plays a key role in the diagnosis of factitious hypoglycemia. Since the results of biochemical and hormonal analyzes in patients with hypoglycemia due to reception of oral hypoglycemic medications and pancreatogenous HGS are identical, the only way to differentiate these conditions is by detection of insulin secretagogue substances in the blood (or urine).</p><p>The determination of oral hypoglycemic medications in cases of suspicion of artificial reception is not implemented in Russia. Factitious hypoglycemia in most cases is the diagnosis of exclusion, and its confirmation if often based on detection of medications among the personal effects of patient. This is a significant difficulty given the ethical standards. However, since 2018 we conduct in our Centre the determination of 7 oral hypoglycemic medications (glibenclamide, gliquidone, gliclazide, glimepiride, glipizide, nateglinide and repaglinide) in patient’s blood using the liquid chromatography–tandem mass spectrometry (LC-MS). This article presents a clinical case of a patient without diabetes mellitus taking glibenclamide and detection of this drug using highly selective LC-MS.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром Мюнхгаузена</kwd><kwd>артифициальная гипогликемия</kwd><kwd>высокоэффективная жидкостная хроматография с тандемной масс-спектрометрией</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Munchausen syndrome</kwd><kwd>factitious hypoglycemia</kwd><kwd>highly selective liquid chromatography-tandem mass spectrometry</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">Kinns H., Housley D., Freedman D.B.
