Pancreatogenic diabetes mellitus, also termed type 3c diabetes (T3cD), or glucose intolerance develops in 25%-75% of adults with chronic pancreatitis (CP). The primary pathophysiologic defect in T3cD is insulin deficiency, thought to result largely from "bystander" injury to the islets from fibrotic changes in the exocrine pancreas and cytokine-induced beta cell dysfunction from intrapancreatic inflammation..

Endoscopic Management of Benign Pancreaticobiliary Disorders.
J Clin Med

Division of Gastroenterology and Hepatology, Center for Digestive Health, Virginia Mason, Franciscan Health, Seattle, WA 98101, USA.
Endoscopic management of benign pancreaticobiliary disorders encompasses a range of procedures designed to address complications in gallstone disease, choledocholithiasis, and pancreatic disorders. Acute cholecystitis is typically treated with cholecystectomy or percutaneous drainage (PT-GBD), but for high-risk or future surgical candidates, alternative decompression methods, such as endoscopic transpapillary gallbladder drainage (ETP-GBD), and endoscopic ultrasound (EUS)-guided gallbladder drainage (EUS-GBD), are effective. PT-GBD is associated with significant discomfort as well as variable adverse event rates.

Background: Abdominal pain is one of the most prominent symptoms in patients with chronic pancreatitis (CP) and can manifest intermittently or persistently. The mechanism of pain is not yet clear, and no effective treatment is currently available. This study aimed to explore the risk factors for pain in patients with CP, which may provide new insights for developing effective pain control modalities.

Background: Total pancreatectomy and intraportal islet cell auto transplantation (TPIAT) is increasingly being offered to patients with refractory chronic pancreatitis. Understanding factors that impact islet function over time is critical.
Study Design: We evaluated factors associated with islet function over 12 years post TPIAT using mixed meal tolerance testing (MMTT).
Association between dietary mineral intake and new onset diabetes/pre-diabetes after chronic pancreatitis.

Department of Gastroenterology, The Affiliated Hospital to Qingdao University, Qingdao, China.
Background And Aims: As the main type of pancreatic diabetes, patients with new diabetes after chronic pancreatitis are often difficult to manage and have poor prognosis. This study aimed to figure out the association between dietary mineral intake and glucose metabolism with chronic pancreatitis.
Method: The study included 114 patients with chronic pancreatitis, who were grouped based on the sequence of onset for chronic pancreatitis and diabetes: normoglycaemia after chronic pancreatitis (NCP), type 2 diabetes (T2DM), and new-onset diabetes or pre-diabetes after chronic pancreatitis (NODCP).
Identification of a vimentin-expressing α-cell phenotype in CF and normal pancreas.

Endocrine dysfunction and diabetes can develop secondary to fibrotic diseases within the pancreas including cystic fibrosis (CF). Phenotypic shift within epithelial cells has been recognised in association with pro-fibrotic signalling. We sought evidence of endocrine cell epithelial-to-mesenchymal transition in CF and non-CF pancreas.
