简要总结
Chronic pancreatitis (CP) is a chronic inflammatory disease of the pancreas characterized by irreversible morphological change and typically causing pain and/or permanent loss of function(1), reduction in digestive enzyme secretion (pancreatic exocrine insufficiency) and endocrine dysfunction/diabetes (DM) (2). Pancreatic exocrine insufficiency (PEI) results in maldigestion of fat and other nutrients thereby culminating in malnutrition and metabolic abnormalities(2). There is a high prevalence of fat-soluble vitamin deficiencies, osteopathy, and malnutrition in chronic pancreatitis, which is underestimated due to a lack of effective diagnosis and suboptimal therapies for pancreatic exocrine insufficiency(3).Pancreatic exocrine insufficiency characterized by inadequate pancreatic secretion of digestive enzymes and bicarbonate, is one of the most significant complications of chronic pancreatitis, affecting >50% of diagnosed patients(4).
Objectives
(A) Primary
1. To compare thegut microbiome, and fecal, serum and tissue metabolome in patients of chronic pancreatitis withoutpancreatic exocrine insufficiency and patients of chronic pancreatitis withexocrine pancreatic insufficiency with healthy controls
2. To determine the effect of pancreaticenzyme replacement therapy on gut microbiome, and fecal, serum and tissue metabolomein patients of chronic pancreatitis with pancreatic exocrine insufficiency
(B) Secondary
1. To knowthe effect of pancreatic enzyme replacement therapy on the levels ofinflammatory cytokines in patients with chronic pancreatitis
2. To know theeffect of pancreatic enzyme replacement therapy on gut-barrier and absorption functionand small intestinal bacterial overgrowth (SIBO) in patients with chronicpancreatitis
3. To studythe effect of pancreatic enzyme replacement therapy on anthropometricmeasurement, body composition and quality of life in patients with chronicpancreatitis
