Intracerebral hemorrhage (ICH)-induced brain injury is a continuous pathological process that involves the deterioration of neurological functions, such as sensory, cognitive or motor functions. Cytotoxic byproducts of red blood cell lysis, especially free iron, appear to be a significant pathophysiologic mechanism leading to ICH-induced injury. Free iron has a crucial role in secondary brain injury after ICH. Chelating iron may attenuate iron-induced neurotoxicity and may be developed as a therapeutic candidate for ICH treatment. In this review, we focused on the potential role of iron toxicity in ICH-induced injury and iron chelation therapy in the management of ICH. It will hopefully advance our understanding of the pathogenesis of ICH and lead to new approaches for treatment.
脑出血(ICH)引起的脑损伤是一个连续的病理过程,涉及神经功能的恶化,如感觉、认知或运动功能。红细胞溶解的细胞毒性副产物,特别是游离铁,似乎是导致 ICH 引起损伤的重要病理生理机制。游离铁在 ICH 后继发性脑损伤中起关键作用。螯合铁可以减轻铁诱导的神经毒性,可能被开发为 ICH 治疗的治疗候选物。在这篇综述中,我们重点介绍了铁毒性在 ICH 引起的损伤中的潜在作用以及铁螯合疗法在 ICH 治疗中的应用。这有望加深我们对 ICH 发病机制的理解,并为治疗提供新的方法。
