Уровень аутоантител к основному белку миелина и особенности микроструктуры трактов белого вещества головного мозга у больных из группы ультравысокого риска по развитию шизофрении

Уровень аутоантител к основному белку миелина и особенности микроструктуры трактов белого вещества головного мозга у больных из группы ультравысокого риска по развитию шизофрении

Abstract

Objective: Analisis of the relationship between the level of AAB to MBP and markers of status pathways of the brain. Methods: 26 juvenile patients, identified psychopathological symptoms that meet the criteria for ultra-high risk of manifestation of schizophrenia were examined. To determine the level of AAB to MBP used enzyme-linked immunosorbent assay. MRI scan were performed: T1-weighted scan for each patients performed an automatic reconstruction of 18 white matter tracts by determining the fractional anisotropy (FA) and radial diffusion (RD) for each of the paths. Results: A correlation was found between the level of AAB to MBP and FA in the parietal part of the right upper longitudinal beam; between the level of AAB to MBP and rate of RD in the temporal and parietal parts of the right upper longitudinal beam. Conclusion. The decrease of fractional anisotropy is associated with the processes that cause violations of structure of the white matter, and increased radial diffusion with pathology of myelin sheaths. Revealed a certain interrelation of these processes with a high level of autoantibodies to myelin basic protein.

Цель: Анализ взаимосвязей между уровнем аАТ к ОБМ и маркерами состояния проводящих путей головного мозга. Методы: обследовано 26 пациентов юношеского возраста, с выявленными психопатологическими симптомами, соответствующими критериям ультравысокого риска манифестации шизофрении. Для определения уровня аАТ к ОБМ использован иммуноферментный анализ. Выполнено МРТ-исследование: Т1-взвешенное сканирование, для каждого пациента проведена автоматическая реконструкция 18 трактов белого вещества с определением фракционной анизотропии (ФА) и радиальной диффузии (РД) для каждого из путей. Результаты: выявлена взаимосвязь между уровнем аАТ к ОБМ и ФС в теменной части правого верхнего продольного пучка; между уровнем аАТ к ОБМ и показателем РД в височной и теменной части правого верхнего продольного пучка. Снижение фракционной анизотропии связывают с процессами, вызывающими нарушения структурированности белого вещества, а увеличение радиальной диффузии с патологией миелиновых оболочек. Выявлена определенная взаимосвязь этих процессов с высоким уровнем аутоантител к основному белку миелина.
