Venous and Arterial TNF-R1 Predicts Outcome and Complications in Acute Subarach...
Fragata, I; Bustamante, A; Penalba, A; Ferreira, P; Paiva Nunes, A; Canhão, P; Montaner, JBackground: There is increasing evidence for the role of inflammation in clinical outcome after subarachnoid hemorrhage (SAH). Specifically, the TNF-alfa(α) pathway seems to be relevant after SAH. Although the TNF-α main receptor, TNF-R1 is associated with aneurysm growth and rupture, its relation to prognosis is unknown. We sought to compare TNF-R1 levels in peripheral venous blood and arterial blood closer to...
Usefulness of TNFR1 As Biomarker of Intracranial Aneurysm in Patients with Spon...
Torres, R; Mancha, F; Bustamante, A; Canhao, P; Fragata, I; Montaner, JAim: To determine the utility of TNF-α receptor (TNFR1) as a biomarker for the presence of aneurysms in patients with acute subarachnoid hemorrhage (SAH). Patient & methods: This is a prospective study in patients with acute spontaneous SAH. Arterial blood from catheter near aneurysm and peripheral venous blood samples are collected. TNFR1 levels were analyzed in patients with and without aneurysm. Results: 80 ...
