Recent data have shown that lysosomal storage disorders (LSD), characterized by a decrease in enzyme activity and a corresponding accumulation of substrate in lysosomes due to mutations in lysosomal genes, can manifest a wide range of clinical symptoms including psychosis, affective disorders, early onset dementia and schizophrenia. The purpose of this study was to assess the level of lysosphingolipids in patients with schizophrenia, Parkinson’s disease (PD) and control. The study included 52 patients with schizophrenia, 170 patients with PD patients and 166 neurologically healthy individuals (control group). Concentration of lysosomal substrates (hexosylsphingosine (HexSph), globotriaosylsphingosine (LysoGb3), lysosphingomyelin (LysoSM)) were measured by high-liquid chromatography with tandem mass spectrometry (HPLC-MS/MS) in blood. An increase in the concentration of LysoSM, LysoGb3, HexSph was detected in patients with schizophrenia compared to control (<italic>p</italic> &lt; 0.0001, <italic>p</italic> &lt; 0.0001, <italic>p</italic> &lt; 0.0001, respectively). Our results confirm a violation of the lysosphingolipid composition of the blood in patients with schizophrenia.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181323879104">Шизофрения представляет собой психическое расстройство и характеризуется нарушением передачи дофамина в нейронах. Последние данные показали, что лизосомные болезни накопления (ЛБН), сопровождающиеся снижением активности ферментов и соответствующим накоплением субстрата в лизосомах из-за мутаций в лизосомных генах, могут проявляться широким спектром клинических проявлений, включая психозы, аффективные расстройства, деменцию с ранним началом и шизофренией. Цель настоящего исследования заключалась в оценке уровня лизосфинголипидов у пациентов с шизофренией, болезнью Паркинсона (БП) и контроле. В исследование включены 52 пациента с шизофренией, 170 пациентов с БП и 166 неврологически здоровых лиц (контрольная группа). Концентрацию лизосомных субстратов (гексозилсфингозин (HexSph), глоботриаозилсфингозин (LysoGb3), лизосфингомиелин (LysoSM)) определяли высокоэффективной жидкостной хроматографией в сочетании с тандемной масс-спектрометрией (ВЭЖХ-МС/МС) в крови. Выявлено повышение концентрации LysoSM, LysoGb3, HexSph у пациентов с шизофренией по сравнению с контролем (<italic>p</italic> &lt; 0.0001, <italic>p</italic> &lt; 0.0001, <italic>p</italic> &lt; 0.0001 соответственно).
