Diabetes following acute pancreatitis. The lancet. Gastroenterology & hepatology Diabetes represents a group of diseases involving persistent hyperglycaemia. Exocrine disorders of the pancreas are increasingly recognised to cause or precede the onset of diabetes, which in this context is referred to as pancreatogenic or type 3c diabetes. Diabetes, as a sequela of acute pancreatitis, is observed across the spectrum of severity in acute pancreatitis and can be associated with other clinical complications. The pathophysiology of acute pancreatitis-related diabetes is poorly understood, and observations suggest that it is probably multifactorial. In this Review, we discuss the epidemiology, pathophysiology, and management considerations of diabetes following acute pancreatitis, and highlight knowledge gaps in this topic. 10.1016/S2468-1253(21)00019-4

Type 3c (pancreatogenic) diabetes mellitus secondary to chronic pancreatitis and pancreatic cancer.

Gastroenterology & hepatology Diabetes mellitus is a group of diseases defined by persistent hyperglycaemia. Type 2 diabetes, the most prevalent form, is characterised initially by impaired insulin sensitivity and subsequently by an inadequate compensatory insulin response. Diabetes can also develop as a direct consequence of other diseases, including diseases of the exocrine pancreas. Historically, diabetes due to diseases of the exocrine pancreas was described as pancreatogenic or pancreatogenous diabetes mellitus, but recent literature refers to it as type 3c diabetes. It is important to note that type 3c diabetes is not a single entity; it occurs because of a variety of exocrine pancreatic diseases with varying mechanisms of hyperglycaemia. The most commonly identified causes of type 3c diabetes are chronic pancreatitis, pancreatic ductal adenocarcinoma, haemochromatosis, cystic fibrosis, and previous pancreatic surgery. In this Review, we discuss the epidemiology, pathogenesis, and clinical relevance of type 3c diabetes secondary to chronic pancreatitis and pancreatic ductal adenocarcinoma, and highlight several important knowledge gaps. 10.1016/S2468-1253(16)30106-6
