We present a protocol for the evaluation of prognostic accuracy of brain injury markers after cardiac arrest. The aim is to define the best predictive marker and to establish clinically useful cut-off levels for routine implementation.Prospective international multicenter trial within the Targeted Hypothermia versus Targeted Normothermia after Out-of-Hospital Cardiac Arrest (TTM2) trial in collaboration with Roche Diagnostics International AG. Samples were collected 0, 24, 48, and 72 hours after randomisation (serum) and 0 and 48 hours after randomisation (plasma), and pre-analytically processed at each site before storage in a central biobank. Routine markers neuron-specific enolase (NSE) and S100B, and neurofilament light, total-tau and glial fibrillary acidic protein will be batch analysed using novel Elecsys® electrochemiluminescence immunoassays on a Cobas e601 instrument.Statistical analysis will be reported according to the Standards for Reporting Diagnostic accuracy studies (STARD) and will include comparisons for prediction of good versus poor functional outcome at six months post-arrest, by modified Rankin Scale (0-3 vs. 4-6), using logistic regression models and receiver operating characteristics curves, evaluation of mortality at six months according to biomarker levels and establishment of cut-off values for prediction of poor neurological outcome at 95-100% specificities.This prospective trial may establish a standard methodology and clinically appropriate cut-off levels for the optimal biomarker of brain injury which predicts poor neurological outcome after cardiac arrest.© 2022 The Authors.Moseby-KnappeMarionMDepartment of Clinical Sciences Lund, Neurology, Lund University, Skåne University Hospital, Lund, Sweden.LevinHelenaHDepartment of Clinical Sciences Lund, Anaesthesiology and Intensive Care, Research and Education, Lund University, Skåne University Hospital, Lund, Sweden.BlennowKajKDepartment of Psychiatry and Neurochemistry, Institute of Neuroscience & Physiology, The Sahlgrenska Academy, University of Gothenburg, Sweden.Clinical Neurochemistry Laboratory, Sahlgrenska University Hospital, Mölndal, Sweden.UllénSusannSClinical Studies Sweden - Forum South, Skåne University Hospital, Lund, Sweden.ZetterbergHenrikHDepartment of Psychiatry and Neurochemistry, Institute of Neuroscience & Physiology, The Sahlgrenska Academy, University of Gothenburg, Sweden.Clinical Neurochemistry Laboratory, Sahlgrenska University Hospital, Mölndal, Sweden.Department of Neurodegenerative Disease, UCL Institute of Neurology, Queen Square, London, United Kingdom.UK Dementia Research Institute at UCL, London, United Kingdom.Hong Kong Center for Neurodegenerative Diseases, Clear Water Bay, Hong Kong, China.LiljaGiselaGDepartment of Clinical Sciences Lund, Neurology, Lund University, Skåne University Hospital, Lund, Sweden.DankiewiczJosefJDepartment of Clinical Sciences Lund, Cardiology, Lund University, Skåne University Hospital, Lund, Sweden.JakobsenJanus ChristianJCThe Copenhagen Trial Unit, Centre for Clinical Intervention Research, Denmark.Department of Regional Health Research, The Faculty of Health Sciences, University of Southern Denmark, Denmark.LagebrantAliceADepartment of Clinical Sciences Lund, Neurology, Lund University, Skåne University Hospital, Lund, Sweden.FribergHansHDepartment of Clinical Sciences Lund, Anaesthesia and Intensive Care, Lund University, Skåne University Hospital, Malmö, Sweden.NicholAlistairAUniversity College Dublin, Clinical Research Centre, St Vincent's University Hospital Dublin, Ireland.The Australian and New Zealand Intensive Care Research Centre, Monash University, Melbourne.
