Metabolomics biomarkers to predict outcomes after subarachnoid hemorrhage
Official title: New Predictive Models for Subarachnoid Hemorrhage - an Exploratory Study on Metabolomics
Run by Unidade Local de Saude Sao Jose · NCT07865182 · Data updated 2026-11-12
This study tests whether blood and CSF biomarkers, together with clinical data, can predict recovery a year after spontaneous subarachnoid hemorrhage in adults treated in Lisbon.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with acute spontaneous SAH admitted to the Neurocritical Care and Trauma Unit at Unidade Local de Saúde São José in Lisbon.
✕Probably not a fit
Patients who do not survive to ICU admission or whose care is not influenced by prognosis modeling may not derive predictive benefit.

What this trial studies
This is a single-center, prospective observational study of adults with acute spontaneous SAH admitted to a neurocritical care unit in Lisbon. Researchers collect blood and cerebrospinal fluid samples on days 1, 3 and 7 and combine metabolomic data with clinical scales, imaging, neuromonitoring, and routine labs to develop a prognostic model for long-term outcome. The goal is to identify metabolites linked to death or long-term disability and see if a predictive model can forecast recovery one year after discharge. Participants receive standard medical care; the study does not modify treatment decisions. Techniques include FT-IR spectroscopy as a potential low-cost method to translate findings into clinical practice.
Why it matters
Potential benefit: If successful, the study could yield a new biomarker-based tool to help predict long-term outcomes after SAH and guide prognosis and care planning.
How similar studies have gone: Previous work suggests metabolites in blood and CSF can relate to SAH outcomes, though integrated multi-modal prediction models remain exploratory.
