Acute pancreatitis(AP),one of the most common acute abdominal conditions in clinical practice,is typically self-limiting.However,approximately 20%of cases progress to severe acute pancreatitis,characterized by persistent systemic inflammatory response syndrome and multiple-organ dysfunction syndrome,with a high mortality rates.The pathogenesis of AP involves complex pathophysiological processes,and in recent years,the role of oxidative stress(OS)in AP has garnered increasing attention.OS refers to an imbalance between reactive oxygen species production and antioxidant capacity following endogenous or exogenous stimuli,which can lead to pancreatic cell injury,exacerbation of inflammatory responses,and organ dysfunction.Notably,antioxidants have demonstrated efficacy in reducing OS-induced pancreatic damage and multi-organ dysfunction in animal models.This article reviews current molecular mechanisms of OS in AP,its role in disease progression and recent advances in antioxidant-based therapeutic strategies for AP.
