Understanding biomarkers in patients with spontaneous subarachnoid hemorrhage

Hemodynamic Instability of Patient With Spontaneous Subarachnoid Hemorrhage and Systemic Response to Endogenous Stress. Urinary and Serum Factors and Clinical Developments. Pilot Study Toward the Predictivity of Clinical Failure and Variation on Outcome in the Neurosurgical Patient (HISAHES)

Observational Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT06218654

This study is trying to see if certain blood and urine markers can help predict how well people with spontaneous subarachnoid hemorrhage will do after their condition.

What this trial studies

This observational study aims to investigate the role of various biomarkers in predicting the clinical outcomes of patients with spontaneous subarachnoid hemorrhage (sSAH). Participants will provide regular blood and urinary samples to measure levels of specific biomarkers, including cardiac troponin, natriuretic peptides, and others. The study seeks to identify which biomarkers can serve as prognostic indicators and establish threshold levels that may predict patient outcomes. By analyzing these biomarkers, the study hopes to enhance understanding of the hemodynamic instability associated with sSAH.

Who should consider this trial

Good fit: Ideal candidates for this study are adult patients diagnosed with spontaneous subarachnoid hemorrhage confirmed through neuroimaging.

Not a fit: Patients under 18 years old or those with post-traumatic subarachnoid hemorrhage will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prognostic tools for predicting outcomes in patients with spontaneous subarachnoid hemorrhage.

How similar studies have performed: While the approach of using biomarkers in sSAH is being explored, this specific study's focus on a comprehensive panel of biomarkers is relatively novel.
