One of the leading somatic comorbidities associated with schizophrenia is cardiovascular disease, which has been estimated to be one of the leading causes of excess mortality in patients diagnosed with schizophrenia. Although the shared susceptibility to schizophrenia and cardiovascular disease is well established, the mechanisms linking these two disorders are not well understood. Genetic studies have hinted toward shared lipid metabolism abnormalities co-occurring in the two disorders, while lipid compounds have emerged as prognostic markers for cardiovascular disease. In particular, three ceramide species in the blood plasma, Cer(d18:1/16:0), Cer(d18:1/18:0), and Cer(d18:1/24:1), have been robustly linked to the latter disorder.</p> <p><bold>AIM: </bold>We aimed to assess the differences in abundances of Cer(d18:1/16:0), Cer(d18:1/18:0), and Cer(d18:1/24:1) in the blood plasma of schizophrenia patients compared to healthy controls.</p> <p><bold>METHODS: </bold>We measured the abundances of Cer(d18:1/16:0), Cer(d18:1/18:0), and Cer(d18:1/24:1) in a cohort of 82 patients with schizophrenia and 138 controls without a psychiatric diagnosis and validated the results using an independent cohort of 26 patients with schizophrenia, 55 control individuals, and 19 patients experiencing a first psychotic episode.</p> <p><bold>RESULTS:</bold> We found significant alterations for all three ceramide species Cer(d18:1/16:0), Cer(d18:1/18:0), and Cer(d18:1/24:1) and a particularly strong difference in concentrations between psychiatric patients and controls for the ceramide species Cer(d18:1/18:0).</p> <p><bold>CONCLUSIONS:</bold> The alteration of Cer(d18:1/16:0), Cer(d18:1/18:0), and Cer(d18:1/24:1) levels in the blood plasma might be a manifestation of metabolic abnormalities common to both schizophrenia and cardiovascular disease.</p></abstract><trans-abstract xml:lang="ru"><p><bold>АКТУАЛЬНОСТЬ:</bold> Шизофрения является не только психическим заболеванием, но и влияет на физическое здоровье людей. Одними из основных сопутствующих соматических заболеваний, связанных с шизофренией, являются сердечно-сосудистые заболевания, считающиеся одной из основных причин повышенной смертности у пациентов с диагнозом шизофрения. Хотя общая предрасположенность к шизофрении и сердечно-сосудистым заболеваниям хорошо известна, механизмы, связывающие эти два расстройства, недостаточно изучены. Генетические исследования указали на общие аномалии липидного обмена, сопутствующие этим двум расстройствам, в то время как липидные соединения были идентифицированы как прогностические маркеры сердечно-сосудистых заболеваний. В частности, три представителя церамидов, определенной группы липидов, в плазме крови, Cer (d18: 1/16: 0), Cer (d18: 1/18: 0) и Cer (d18: 1/24: 1), были ассоциированы с риском сердечно-сосудистых заболеваний.</p> <p><bold>ЦЕЛИ:</bold> Мы оценивали различия в содержании Cer (d18: 1/16: 0), Cer (d18: 1/18: 0) и Cer (d18: 1/24: 1) в плазме крови больных шизофренией по сравнению с контрольной группой.</p> <p><bold>МАТЕРИАЛ И МЕТОДЫ: </bold>Мы измерили содержание Cer (d18: 1/16: 0), Cer (d18: 1/18: 0) и Cer (d18: 1/24: 1) в когорте из 82 пациентов с шизофренией и 138 человек из контрольной группы без психиатрического диагноза и, далее, подтвердили результаты анализа в слепом исследовании независимой когорты из 26 пациентов с шизофренией, 55 человек из контрольной группы и 19 пациентов, перенесших первый психотический эпизод.</p> <p><bold>РЕЗУЛЬТАТЫ:</bold> Мы обнаружили значительные изменения для всех трех видов церамидов Cer (d18: 1/16: 0), Cer (d18: 1/18: 0) и Cer (d18: 1/24: 1). Среди этих соединений Cer (d18: 1/18: 0) показал наиболее сильные наибольшую разницу между пациентами и контрольной группой.</p> <p><bold>ВЫВОДЫ: </bold>Изменение уровней Cer (d18: 1/16: 0), Cer (d18: 1/18: 0) и Cer (d18: 1/24: 1) в плазме крови может быть проявлением метаболических аномалий, общих для как шизофрении, так и сердечно-сосудистых заболеваний.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ceramide</kwd><kwd>schizophrenia</kwd><kwd>cardiovascular disease</kwd><kwd>lipid</kwd><kwd>blood plasma</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>церамиды</kwd><kwd>шизофрения</kwd><kwd>сердечно-сосудистые заболевания</kwd><kwd>липиды</kwd><kwd>плазма крови</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Mitchell AJ, Vancampfort D, Sweers K, et al.
