Copeptin and the S-100b Protein in Stroke

June 3, 2019 updated by: Poitiers University Hospital

Value of Copeptin and the S-100b Protein Assay in Ruling Out the Diagnosis of Stroke-induced Dizziness Pattern in Emergency Departments

This study evaluated the value of using copetin and protein S 100 b to eliminate the diagnosis of stroke in patients presenting with vertigo in emergency departments. All patients benefited from the S 100b protein assay, copeptin and brain MRI.

Detailed Description

Vertigo is a frequent reason for visiting emergency departments. Differentiating stroke from other causes is challenging for physicians. The role of biomarkers has been poorly assessed. Evaluators evaluated whether copeptin and S100b protein assessment, alone or in combination, could rule out stroke in patients visiting emergency departments for vertigo.

Evaluators included patients visiting the adult emergency departments of a French university hospital for a new episode of vertigo evolving for less than 72 hours. All patients underwent standardized physical examination (HINT [Head Impulse test, Nystagmus, test of skew deviation] maneuvers), copeptin and S-100b protein measurement and injected brain imaging. Stroke diagnosis involved diffusion-weighted magnetic resonance imaging or, if not available, neurological examination and contrast brain CT scan compatible with the diagnosis.

Study Population

One hundred and fifty-one patients were included, of whom 16 were secondarily excluded (lost to follow-up n=1, missing biomarkers n=9, missing MRI n=6)(Figure 1). A majority of the remaining 135 patients were women (n=79, 59%) with an average age of 62 years . Specialized advice on the origin of dizziness was sought from ENT and/or neurologist in 102 (76%) of cases. Patients received brain diffusion-weighted MRI alone in 74 cases, contrast brain CT alone in 11 cases and a combination of MRI and CT in 50 cases. In 122 patients (90%), vertigo was not related to stroke.

Description

Inclusion Criteria:

  • We included patients 18 years of age or older, visiting the ED for a new episode of dizziness evolving less than 72 hours and having given written consent to participate in the study

Exclusion Criteria:

  • Patients without brain imaging (diffusion-weighted magnetic resonance imaging (MRI) or contrast CT scan compatible with the diagnosis) were excluded.
