| Popis: | Ischemic stroke is considered as one of the most frequent and severe complications of atrial fibrillation. The present study was undertaken to examine whether post-insult treatment with cytidine diphosphate-choline (CDP-choline, or citicoline) affects serum levels of the angiogenesis inhibitor angiostatin and neurospecific proteins as markers of brain damage in patients with cerebral ischemia associated with atrial fibrillation. Thirty-three patients with a diagnosis of acute ischemic stroke received citicoline sodium by intravenous infusions (1,000 mg daily for 14 days) in addition to the standard treatment (basic group). Twenty-five patients with the same pathologies, who received only standard therapy, were enrolled in the study as a control group. Serum content of angiostatin and neurospecific proteins, namely neurofilament heavy subunit (NF-H) and glial fibrillary acidic protein (GFAP), was measured by immunoblotting at the basal level and after the treatment. Citicoline treatment caused significant decreases in serum levels of angiostatin (by 40% vs. basal level, P < 0.05), GFAP (by 61%, P < 0.01), and the NF-H subunit (by 19%, P < 0.05) and had no effect on the serum albumin content. In contrast, there were no statistically significant differences between baseline levels of the studied protein markers and their content after the treatment period in the control group. These findings indicate for the first time that CDP-choline protects both astrocytes and neurons and improves angiogenic capacity through down-regulation of angiostatin in post-ischemic patients with atrial fibrillation after acute ischemic stroke. Further studies are needed to test associations between serum levels of these biomarkers, clinical outcomes, and treatment efficacy of stroke. |
