Outcome Measures

Primary Outcomes (3)

  • change in hippocampal volume as assessed by manual delineation following an initial automatic segmentation

    Hippocampal volumes were normalized using the following equation: normalised hippocampal volume = original hippocampal volume - linear regression coefficient x (total intracranial volume - mean total intracranial volume). The coefficient was derived from a linear regression of total intracranial volume and original hippocampal volume. Total intracranial volume was obtained from an automated segmentation of grey matter, white matter and cerebrospinal fluid. Intra-rater reliability was determined using randomly selected scans segmented at two time-points at least one month apart. The intra-class correlation coefficient (Cronbach's alfa) was 0.96 for the left hippocampus and 0.95 for the right hippocampus.

    6 months

  • change in brain derived neurotrophic factor as assessed by the Emax Immuno Assay system

    Blood samples were taken between 07:30 am and 09:30 am after an overnight fast. Serum was immediately separated and stored at -85 °celcius until assayed. BDNF protein levels were measured using the Emax Immuno Assay system from Promega according to the manufacturer's protocol (Madison, United States of America), in one laboratory (Maastricht University). Undiluted serum was acid treated as this reliably increased the detectable BDNF in a dilution-dependent way. Greiner Bio-One high affinity 96-well plates were used. Serum samples were diluted 100 times, and the absorbency was read in duplicate using a Bio-Rad (Hercules, United States of America) Benchmark microplate reader at 450 nm.

    4 weeks

  • change of mood as assessed by the Montgomery-Ă…sberg Depression Rating Scale (MADRS)

    The MADRS is a ten-item diagnostic questionnaire which psychiatrists use to measure the severity of depressive episodes in patients with mood disorders. Higher MADRS score indicates more severe depression, and each item yields a score of 0 to 6. The overall score ranges from 0 to 60. The questionnaire includes questions on the following symptoms: apparent sadness; reported sadness; inner tension; reduced sleep; reduced appetite; concentration difficulties; lassitude; inability to feel; pessimistic thoughts; suicidal thoughts.

  • change of cognition as assessed by the mini mental state examination

    up to 1 year

  • change of psychomotor symptoms as assessed by the CORE (not an acronym)

    up to 1 year

Study Arms (1)

electroconvulsive therapy

OTHER

only one arm in this study: patients who are treated with electroconvulsive therapy and have been given anesthesia with etomidate and succinylcholine

Procedure: ECTDrug: EtomidateDrug: Succinylcholine

Interventions

ECTPROCEDURE

ECT was administered twice a week with a constant-current brief-pulse device (Thymatron, System IV). Motor and electroencephalographic seizures were monitored to ensure adequate duration and quality. Subjects were all treated with right unilateral (RUL) ECT with stimulus intensity 6 times the initial seizure threshold (ST), as determined by empirical dose titration at the first treatment, until remission (Montgomery-Ă…sberg Depression Rating Scale (MADRS) (27) \< 10 in two consecutive ratings with a week interval). Subjects who failed to respond right unilateral ECT after the sixth treatment were switched to bitemporal ECT (1.5x seizure threshold).

Anesthesia was achieved with intravenous administration of etomidate (0.2mg/kg).

Anesthesia was achieved with intravenous administration of succinylcholine (1mg/kg).
