Role of Oxidative Stress in the Pathogenesis of Pancreatitis: Effect of Antioxidant Therapy.

Oxidative stress plays an important role in the pathogenesis of acute pancreatitis. The exact pathogenesis of pancreatitis remains unknown but several mechanisms related to oxidative and inflammatory stress are implicated. It is reasonable to surmise that antioxidants would play a protective role in ameliorating the deleterious effects of pancreatitis. We have a wealth of data from animal models that reveal a positive correlation between antioxidant drugs and improved outcomes in experimental pancreatitis. Human clinical trials with antioxidants however, have disclosed conflicting results. We review the existing pathogenesis of pancreatitis related to oxidative stress and provide of a review of current trials with antioxidant therapy.
