3yr old, poor growth, elev sed rate, iga, calprotectin. biopsy -chronic stomach inflammation & cryptitis. infection has been ruled out. wht could it b?

IBD: Cryptitis is seen in inflammatory bowel disease, both Crohn's and Ulcerative Colitis, but it also can be seen in other inflammatory conditions of the intestines. It is not a disease itself but a histologic manifestation of several different diseases.Calprotectin is a biochemical test for intestinal inflammation, including inflammatory bowel disease. I hope he is being treated by a pediatric GI Dr.
