Reperfusion Injury

It is caused by reperfusion following ischemia. The grounding supports ischemia-reperfusion as the defining setting, but does not identify additional primary causes beyond the ischemic event and subsequent restoration of blood flow.

The literature grounding links reperfusion injury to multiple injury pathways, including apoptosis, cell death, oxidative stress, inflammatory responses, and neuroinflammation in cerebral ischemia. It also supports involvement of ferroptosis, characterized by iron-dependent lipid peroxidation and reduced antioxidant capacity, as well as signaling networks such as Wnt and complement activation in kidney injury and transplantation settings.

The main risk factor supported by the grounding is prior ischemia followed by reperfusion. The reviewed literature also indicates higher relevance in settings such as ischemic stroke, kidney transplantation, and acute kidney injury, but does not support additional general risk factors.

The grounding supports treatment at the modality and drug-class level only indirectly, mainly through reperfusion-based interventions and investigational neuroprotective or organ-protective strategies. Reported therapeutic areas include thrombolysis and thrombectomy in ischemic stroke, and experimental or clinical attempts targeting neuroinflammation, complement, Wnt-related signaling, ferroptosis, and NAD+ homeostasis.
