Outline of Final Research Achievements

We collected specimens from 11 depressive patients and 9 catatonic schizophrenia patients treated with electroconvulsive therapy (ECT). Depressive patients, with 7 points or less in the Hamilton Depression Rating Scale and 1 or 2 in the Clinical Global Impressions (CGI) on post-ECT period, were defined as remitters. Catatonic patients with schizophrenia, with 0 points in the Bush-Francis Catatonia Rating Scale and 1 or 2 in CGI on post-ECT period, were defined as remitters.
It’s enabled to distinguish between remitters (5 depressive patients and 4 with schizophrenia) and non-remitters (6 depressive patients and 5 with schizophrenia), based on plotted partial least square discriminant analysis (PLS-DA) score of Nuclear Magnetic Resonance (NMR) signals of pre-ECT patient’s serum.

Academic Significance and Societal Importance of the Research Achievements

今回の研究成果は、従来困難であるとされている電気けいれん療法の治療予測が血清から可能となる可能性を示した貴重なものである。今後症例数を増やしての結果の検討を行い、続いて今回の研究で得られたパラメータを他の医療機関の患者など、別コホートの検体にも用いることで結果の妥当性を検証する予定である。
