Pancreatic cholera is characterized by all except:
**Core Concept**
Pancreatic cholera refers to a rare but life-threatening condition caused by the production of large amounts of vasoactive intestinal peptide (VIP) by a pancreatic tumor, leading to severe watery diarrhea, hypokalemia, and metabolic acidosis.
**Why the Correct Answer is Right**
The condition is characterized by a marked increase in intestinal secretion, leading to severe diarrhea, due to the action of VIP on intestinal epithelial cells. VIP stimulates adenylate cyclase, increasing intracellular cAMP, which in turn activates the cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel, resulting in chloride and water secretion into the intestinal lumen. The resulting hypokalemia and metabolic acidosis are due to the loss of potassium and bicarbonate ions in the stool.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is likely incorrect, as it may be a characteristic of pancreatic cholera, such as the presence of a pancreatic tumor secreting VIP.
**Option B:** This option is likely incorrect, as it may be a characteristic of pancreatic cholera, such as severe watery diarrhea.
**Option C:** This option is likely incorrect, as it may be a characteristic of pancreatic cholera, such as hypokalemia and metabolic acidosis.
**Clinical Pearl / High-Yield Fact**
The condition is often associated with a pancreatic tumor, which can be a gastrinoma, VIPoma, or somatostatinoma, and can be treated with somatostatin analogs or surgery.
