Serum amyloid A, fetuin-A, and pentraxin-3 levels in patients with ischemic stroke: novel prognostic biomarkers?

Aim: Inflammation plays an important role in acute ischemic stroke. In this study we aimed to investigate the relationship between acute ischemic stroke and serum amyloid A, fetuin-A, and pentraxin-3 which are inflammation markers. Materials and methods: We enrolled 52 patients with acute ischemic stroke and 30 sex-matched control subjects in the study. The patients were followed for 3 months. We evaluated the common risk factors, laboratory variables, and neurological examination of stroke patients according to prognosis scales. Results: The median serum amyloid A, fetuin-A, and pentraxin-3 levels in the stroke patients were higher than in control subjects (respectively, P = 0.000, P = 0.002, and P = 0.037). National Institutes of Health Stroke Scale scores, glucose, C-reactive protein, fibrinogen, and white blood cell count showed differences within the group in terms of the serum amyloid A tertiles statistically. Conclusion: Pentraxin-3, fetuin-A, and serum amyloid A all arise together as novel prognostic factors in a group of patients with ischemic stroke. Relationships between higher levels of inflammation markers, especially serum amyloid A, and the severity of acute ischemic stroke were shown.
