Stories about: diabetic enteropathy

Rescuing intestinal stem cells from attack in diabetes

Blood levels of the hormone IGFBP3 (enterostaminine), shown here in green, are markedly elevated in people with longstanding type 1 diabetes and launch a lethal attack on intestinal stem cells. Adding a protein that soaks up the excess hormone restores normal stem cell function and could help prevent or treat diabetic enteropathy. (All images by Riseon)

Up to 80 percent of people with long-standing type 1 diabetes develop gastrointestinal symptoms—abdominal pain, bloating, nausea, vomiting, diarrhea, constipation and fecal incontinence—that severely diminish quality of life. Recent evidence suggests that this condition, known as diabetic enteropathy, results from damage to the intestinal lining, but the details beyond that have been unclear.

A study in this week’s Cell Stem Cell, led by Paolo Fiorina, MD, PhD, now provides some answers. It demonstrates how diabetes can lead to destruction of the stem cells that maintain the intestinal lining, and identifies a potential drug that could protect these stem cells and prevent or treat diabetic enteropathy.
