Özet
Background: Subarachnoid hemorrhage (SAH) is a severe neurological condition with high mortality and morbidity rates, often exacerbated by secondary complications such as inflammation, cerebral vasospasm, and apoptosis. Proinflammatory cytokines, including interleukin-1 (IL-1), tumor necrosis factor-alpha (TNF-alpha), and interleukin-6 (IL-6), play critical roles in these pathological processes. Anakinra, an IL-1 receptor antagonist, has demonstrated significant anti-inflammatory effects in various disease models. This study aimed to evaluate the efficacy of anakinra in mitigating inflammation, vasospasm, and apoptosis in an experimental rat model of SAH. Methods: Thirty-two male Sprague Dawley rats were divided into four groups: Control (healthy), SAH (no treatment), Saline (0.2 mL saline subcutaneously), and Anakinra (50 mg/kg subcutaneously, twice daily). Proinflammatory markers (CRP, TNF-alpha, IL-1, IL-6, and fibrinogen) were measured in serum and cerebrospinal fluid (CSF) at 3, 7, and 10 days post-SAH. Basilar artery diameter was evaluated histopathologically, and Caspase-3 expression was assessed immunohistochemically to determine apoptotic activity. Results: SAH significantly increased levels of CRP, TNF-alpha, IL-1, IL-6, and fibrinogen in both serum and CSF, reduced basilar artery diameter, and elevated Caspase-3 expression compared to the Control group. Saline treatment provided limited improvements, with inflammatory markers and histopathological parameters remaining elevated. Anakinra treatment significantly reduced inflammatory markers, restored basilar artery diameter, and lowered Caspase-3 expression, highlighting its efficacy in mitigating inflammation, vasospasm, and apoptosis. Conclusions: Anakinra effectively suppresses inflammation, alleviates cerebral vasospasm, and inhibits apoptosis in an experimental model of SAH. These findings suggest its potential as a therapeutic agent for managing SAH and its complications. Further research is needed to explore its clinical applicability and long-term effects.
