A disturbed intraduodenal milieu and pancreatic scarring in advanced chronic pancreatitis (CP) may lead to changes of gut and pancreatic hormones. In the present study, the gastroduodenal mucosal content of several regulatory peptides was determined in 8 patients with severe calcific CP and 8 healthy volunteers. In addition, hormone release into the bloodstream was estimated after intraduodenal acid/glucose stimulation in the control subjects and 8 CP patients each with or without secondary diabetes mellitus (DM), and in 8 patients with juvenile DM, so that disturbed gut hormone release could be attributed either to CP or DM. While VIP release into the circulation was similar in all participants, mucosal levels of VIP and substance P were significantly elevated in the duodenal bulb and descending duodenum of CP patients. The somatostatin content of gastroduodenal mucosa in CP was at least as high as in normals. Gastrin was significantly more abundant only in the duodenal bulb of CP patients, while plasma gastrin was normal. Duodenal CCK concentrations tended to be elevated in the duodenal bulb, but not significantly. The release of secretin seemed to be higher in type-1 diabetics than in CP patients. The mucosal pattern of GIP was nearly identical in CP patients and controls. Compatible with this finding, the GIP release did not show any peculiarities in CP with or without DM or in DM. Basal and stimulated plasma levels of motilin were abnormally high in CP. Pancreatic polypeptide plasma levels were normal in DM, but significantly reduced in CP, especially in CP with DM. Fasting PP and stimulated pancreatic enzyme outputs were linearly related.(ABSTRACT TRUNCATED AT 250 WORDS)

UI	MeSH Term	Description	Entries
D007413	Intestinal Mucosa	Lining of the INTESTINES, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. In the SMALL INTESTINE, the mucosa is characterized by a series of folds and abundance of absorptive cells (ENTEROCYTES) with MICROVILLI.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009037	Motilin	A peptide of about 22-amino acids isolated from the DUODENUM. At low pH it inhibits gastric motor activity, whereas at high pH it has a stimulating effect.
D009496	Neurotensin	A biologically active tridecapeptide isolated from the hypothalamus. It has been shown to induce hypotension in the rat, to stimulate contraction of guinea pig ileum and rat uterus, and to cause relaxation of rat duodenum. There is also evidence that it acts as both a peripheral and a central nervous system neurotransmitter.
D010191	Pancreatic Polypeptide	A 36-amino acid pancreatic hormone that is secreted mainly by endocrine cells found at the periphery of the ISLETS OF LANGERHANS and adjacent to cells containing SOMATOSTATIN and GLUCAGON. Pancreatic polypeptide (PP), when administered peripherally, can suppress gastric secretion, gastric emptying, pancreatic enzyme secretion, and appetite. A lack of pancreatic polypeptide (PP) has been associated with OBESITY in rats and mice.	Pancreatic Polypeptide (PP),Pancreatic Polypeptide Hormone,Pancreatic Prohormone
D010195	Pancreatitis	INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D004763	Glucagon-Like Peptides	Peptides derived from proglucagon which is also the precursor of pancreatic GLUCAGON. Despite expression of proglucagon in multiple tissues, the major production site of glucagon-like peptides (GLPs) is the INTESTINAL L CELLS. GLPs include glucagon-like peptide 1, glucagon-like peptide 2, and the various truncated forms.
