title: Chronic pancreatitis at Manchester, UK. Focus on antioxidant therapy.
abstract: The Manchester 'oxidant stress' hypothesis for the development of pancreatitis accommodates published information on both chronic pancreatitis and acute pancreatitis. Oxidant stress, mainly from reactive xenobiotic metabolites, is perceived as the pivotal pre-morbid problem in chronic pancreatitis and, by depleting glutathione, targets the exocytosis mechanism of the pancreatic acinar cell. Inhalation exposure to petrochemical products is identified as an independent risk factor in patients at Manchester Royal Infirmary, where some 50% of patients referred have non-alcoholic disease. This paper describes the development of antioxidant therapy, using supplements of methionine, vitamin C and selenium, and its validation in a placebo-controlled trial, followed by a retrospective cross-sectional study in 94 consecutive patients for an average of 30 months. Antioxidant therapy emerges as a safe and effective medical alternative to surgery for painful chronic pancreatitis.
