Modified Electroconvulsive Therapy Normalizes Plasma GNA13… : The Journal of ECT
ed electroconvulsive therapy (MECT). Methods This study recruited 82 SCZ patients and 86 healthy controls (HCs). Each SCZ patient received 6 sessions of MECT. The Positive and Negative Syndrome Scale (PANSS) was used to assess SCZ symptom severity. Plasma levels of GNA13 were measured by enzyme-linked immunosorbent assay. Results Pretreatment, SCZ patients had a higher GNA13 level than HC (t = 8.199, P < 0.001). MECT reduced the GNA13 level significantly (t = 11.13, P < 0.001) and normalized the difference between SCZ and HC (t = 0.219, P = 0.827). After treatment, the downregulation of GNA13 (ΔGNA13) was negatively correlated with the positive symptoms score reduction rate (ΔP) (r = −0.379, P = 0.027) and positively correlated with the negative score reduction rate (ΔN) (r = 0.480, P = 0.004) in females. In both males and females, the receiver operating characteristic curve revealed that the pretreatment GNA13 level could help differentiate SCZ from HC (male: area under the curve = 0.
