About this trial

Investigators will measure the variation of blood Metabolome through 1H NMR at several time points during the course of electroconvulsivetherapy in patients with a major depressive episode. Patients with a major depressive disorder or a bipolar disorder and a current major depressive episode will be included in this study. Investigators hypothesized that Metabolome could be a source to predict response during ECT and to help understanding underlying biological mechanisms.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Major depressive episode according to DSM-5 criteria

Diagnosis of major depressive disorder or bipolar disorder

MADRS score >22

having given written, free and informed consent

Disqualifiers

whose consent is not admissible or who refuse to participate in the study

deprived of liberty by judicial or administrative decision

For which there is a particular risk contraindicating the cure of ECT

Suffering from schizophrenia spectrum disorders or persistent delusional disorder as described by DSM-5 Criterion D for Major Depressive Disorder

Trial design

Design model

Single group

Treatments tested in this trial

  • Electroconvulsive therapy

    Other intervention

    Electroconvulsive therapy is administered through electrodes positioned bilaterally (bitemporal) or unilaterally (or fronto-temporal) on the frontotemporal region under anesthesia. The stimulation dose is determined by titration method, during the first ECT session. An ECT cure corresponding from 12 to 20 sessions of ECT. Patients will receive 2 sessions a week. Blood samples will be done during the anesthesia process.

Trial outcomes

Primary outcomes

1

Value the metabolic profile difference between the baseline and before the 6th session of ECT by blood metabolomics through 1HNMR

identify variations in the metabolome by measuring the metabolome in the blood of patients treated for depressive episodes or bipolar disorder by identifying the metabolic profiles associated with the medical response to ECT between the Baseline and before the sixth ECT session.

Time frame
up to 3 weeks

Secondary outcomes

1

Measure the biological effect of one ECT session on the blood metabolome

Comparison of quantitative and qualitative measurements of metabolites and metabolic signatures obtained by 1HNMR between baseline and the first ECT by observing either a clinical response or a clinical remission by discriminating remitters and no remitters patients.

Time frame
through first ECT session, an average of 1 week
2

Compare the biological effect measured between the baseline and before the 1st, 6th and 12th session of ECT

Comparison of quantitative and qualitative measurements of metabolites and metabolic signatures obtained by 1HNMR between baseline and the first ECT by observing either a clinical response or a clinical remission by discriminating remitters and no remitters patients. The clinical response is defined by the decrease of 50% on the MADRS scale. The clinical remission is defined by a score less than or equal to 10 on the MADRS scale.

Time frame
through study completion, up to 6 weeks
3

Measure the variations of the metabolic signature according to the clinical response during the ECT treatment

Comparison of quantitative and qualitative measures of metabolites taken separately and metabolic signatures obtained by 1H NMR according to the clinical response on the MADRS scale (the overall score thus ranges from 0 to 60) throughout the course of ECT. The clinical response is defined by the decrease of 50% on the MADRS scale. The clinical remission is defined by a score less than or equal to 10 on the MADRS scale.

Time frame
up to 10 weeks
4

Look for a metabolic signature to discriminate between responder and non-responder patients before the 6 ECT sessions (i.e. the day of the 6th)

Comparison of metabolic signatures obtained by very high field NMR between responder and non-responder patients before the 6th ECT session (V2)

Time frame
through the sixth session, up 3 weeks
