Intermittent Fasting for Pancreatitis : Intermittent Fasting as a Primary Means for Improving Quality of Life for Acute and Chronic Pancreatitis

Fasting is a classic means for religious discipline, yet recently regaining favor in the medical landscape. Numerous studies have come forth, both in animals and humans outlining the benefit of intermittent fasting (IF) on various disease states and longevity. Though a relatively complex cellular process, fasting for at least 8-12 hours has been shown to lead to fatty acid release from a patient's adipose storage. These fatty acids then shuttle to the liver, where they are converted to ketones such as beta-hydroxybutyrate and acetoacetate.Ketones are then utilized for energy sources in the heart, brain and skeletal muscle tissue. The energy produced (ATP), then leads to increase in the cellular powerhouses, the mitochondria and autophagy or cell recycling. This cellular recycling is one main way in which IF has proven benefit for inflammatory conditions and in cancer care.Furthermore, reductions in amino acids and glucose due to fasting and reliance on ketones as energy, lead to down regulation of the membrane target of rapamycin (mTOR) pathway. Much is known regarding the mTOR pathway. Down regulation of mTOR is associated with increased autophagy (as above), lower protein and lipid synthesis, ribosome and lysosome creation (cell shuttles) and lowered energy use.Specific to the pancreas, mTOR down regulation has been shown to lower protein synthesis with the pancreas, caused by cholecystokinin (CCK), a pancreas stimulating hormone.2 The effect of this leads to lower pancreatic enzymes secretion. Inhibition of mTOR also lowers the generation of fibroblasts, the scar-tissue cells within the pancreas, leading to less scar-formation.3 Scar tissue formation is a vital part of morbidity and complications for patients with chronic pancreatitis.Pancreatic disease-modulation has also been evaluated in regard to the mTOR pathway.4 For pancreatic cancer, rapamycin a mTOR inhibitor have been implicated as targets for chemotherapy. Clinical trials have shown benefit for pancreatic cancer cases given rapamycin in concert with other chemotherapeutic medications.5 For acute, chronic pancreatitis and post-ndoscopic retrograde cholangiopancreatopgraphy (ERCP) pancreatitis, mTOR is usually activated.6 In particular, blocking the mTOR pathway can favor autophagy, limit cell death (apoptosis) and hence necrosis of the pancreas. Necrosis in pancreatitis, leads to complex disease, possess a higher mortality, organ failure, and can make the clinical course more complicated. Therefore, the mTOR pathway has been implicated as a potential therapeutic target to ameliorate disease course and severity.4,7,8 The purpose of this study is to evaluate IF as a means for limiting disease severity with people who have recurrent acute pancreatitis and chronic pancreatitis. Our hypothesis is that IF will improve pancreatic-disease related quality of life.1.
