Laboratory findings will be correlated to clinical parameters, cognitive measures and psychometric outcome measures. The aim is to elucidate the underlying mechanisms for both treatment effects and cognitive side effects of ECT.', 'detailedDescription': 'Study hypothesis That a combined dataset of biomarker and clinical/ demographic data can be used to identify possible mechanisms of action for ECT or pathophysiological mechanisms underlying major depression.\n\nThe study is based on already (prospectively, observational) collected data and biological material:\n\n* in the Regional ECT Register (Regionalt medisinsk kvalitetsregister for nevrostimulerende behandling i Helse Vest, Datatilsynets konsesjon 2012/5490),\n* the ECT-MRI study approved by REK sørøst "2013/1032 ECT and neuroradiology" with its study specific biobank (Imdep)\n* and the ECT biobank, (Forskningsbiobanken for nevrostimulerende behandling i Helse Vest (REK Vest 2017/925).\n\nBiological samples and demographic/clinical data from those sources will be analyzed together.\n\nAll patients received the standard ECT treatment, as it is provided at the ECT-department at the Haukeland University Hospital.\n\nInclusion criteria:\n\nPatients (age \\> 18) referred to the ECT-unit and accepted for treatment.\n\nExclusion criteria:\n\nPatients unable to give informed consent\n\nData from the current study will be compared to data from the control groups in the ECT-MRI study:\n\n1. a group of patients undergoing ECV for AF (controls 1) and\n2. healthy controls undergoing the same investigations as the ECT patient group, but not receiving ECT or anesthesia (controls 2).\n\nClinical assessments Clinical assessments and monitoring was performed in accordance with the routine assessments at the section for ECT , Haukeland US and described in the Regional Register for ECT (Regionalt medisinsk kvalitetsregister for nevrostimulerende behandling i Helse Vest, Datatilsynets konsesjon 2012/5490).\n\nBlood and saliva biomarkers We will analyze DNA, RNA and blood biomarkers that may be relevant for several hypotheses related to possible pathophysiological mechanisms of major depression, possible mechanisms of action of ECT and changes in biomarkers during depression treatment. Due to the constant progress in the field, the decision on which markers to analyze and how to perform the analyses should not be taken too early. However, candidate markers include neurotrophic factors (e.g. BDNF, CREB), neurotransmitters (e.g. GABA/Glutamate and relevant genetic markers), inflammation factors and markers of damage to the blood-brain barrier. Further, we will assess metabolomic changes from pre to post-treatment and other relevant blood biomarkers.\n\nGenetic analysis (DNA, RNA), such as changes in RNA and DNA methylation from pre to posttreatment, might identify putative areas that are important for the biological mechanisms underlying ECT response and associated with depression /disease development. Further analyses might include Genome-wide association analyses of severe/ treatment resistant depression (GWAS) (patients vs healthy controls), Genome-wide association analyses of ECT response (responders vs nonresponders) and Epigenome-wide association (EWA) analyses of ECT response.\n\nStudies so far suggest that effects of therapy of psychiatric disorders may be detected in peripheral blood. The information on methylation will be collected from both blood and saliva, and EWA analyses will also be performed on both. We will utilize longitudinal data to examine changes in methylation of ECT responders, non-responders and controls to establish possibly long-term and short-term epigenetic changes associated with ECT.\n\nMetabolic and Proteomic analyses of ECT response In ongoing studies, we recently observed significant effects of ECT on serum tryptophan metabolites, including neuroprotective kynurenines. In this study, we will continue our analyses by increasing the sample size and expanding the number of metabolites and proteins that we will examine in relation to ECT response.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Patients (age \\> 18) referred to the ECT-unit and accepted for treatment.', 'eligibilityCriteria': 'Inclusion Criteria:\n\nPatients (age \\> 18) referred to the ECT-unit and accepted for treatment.\n\nExclusion Criteria:\n\nPatients unable to give informed consent'}, 'identificationModule': {'nctId': 'NCT05515159', 'briefTitle': 'Blood Biomarkers in Electroconvulsive Therapy', 'organization': {'class': 'OTHER', 'fullName': 'Haukeland University Hospital'}, 'officialTitle': 'Blood Biomarkers in Electroconvulsive Therapy', 'orgStudyIdInfo': {'id': '51089'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'ECT group', 'description': 'patients undergoing electroconvulsive therapy for depression', 'interventionNames': ['Other: electroconvulsive therapy']}, {'label': 'control group', 'description': 'healthy controls; patients undergoing electroconversion for atrial fibrillation'}], 'interventions': [{'name': 'electroconvulsive therapy', 'type': 'OTHER', 'description': 'electrical stimulation of the brain while the patient is under anesthesia.', 'armGroupLabels': ['ECT group']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Bergen', 'country': 'Norway', 'facility': 'Haukeland University Hospital', 'geoPoint': {'lat': 60.39299, 'lon': 5.32415}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED', 'description': 'Data will be shared on reasonable request'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Haukeland University Hospital', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
