Study IDST000775
Study TitleMichigan Biomarkers for Refractory Depression (Bluebird) metabolomics pilot study
Study TypeMS analysis
Study SummaryThe goal of the project is discovery of clinical useful biomarkers for treatment-resistant depression. All participants were undergoing electroconvulsive therapy (ECT) for treatment-resistant depression (major depressive disorder or bipolar disorder) in 2012-2014. All subjects were Caucasian except BB060, who was Asian. Samples were collected from each subject at baseline just before the first ECT treatment (Time Point T0) and approximately 3 weeks later just before the tenth ECT treatment (Time Point T2). Whole blood was drawn in the morning in a fasted state (at least 7 hours) through an intravenous catheter or butterfly needle into 6-mL EDTA tubes (Lavender Top, Becton Dickinson Vacutainer K2EDTA additive blood collection tube, part #367863) and transported to the processing lab at the Michigan Clinical Research Unit within 30 minutes. Plasma was isolated by centrifugation for 10 minutes at 2000G at 4C. Plasma from multiple tubes was pooled and aliquotted in 200 uL volumes into 2-mL screw-cap cryovials and frozen at -80C.
