Plasma lipopolysaccharide-binding protein (LBP), a proxy for intestinal permeability, relates to clinicopathological and immunological disease activity in inflammatory bowel disease patients at diagnosis and during disease course.
Journal of Crohn's & colitis

Plasma lipopolysaccharide-binding protein (LBP), a proxy for intestinal permeability, relates to clinicopathological and immunological disease activity in inflammatory bowel disease patients at diagnosis and during disease course.

A simple blood marker (LBP) that reflects bacterial exposure across the gut barrier was linked to disease severity and immune activity at diagnosis and during follow-up—especially in ulcerative colitis—so it might help...
