| Outline of Final Research Achievements |
To explore new biomarkers for small intestinal malabsorption, we determined serum concentrations of cholesterol related compounds in patients with CD or ulcerative colitis (UC). The concentrations of 7α-hydroxy-4-cholesten-3-one (C4), a marker for bile acid synthesis, and lathosterol, a marker for cholesterol biosynthesis, were significantly elevated while the levels of fibroblast growth factor 19 (FGF19), a marker for intestinal bile acid flux, and 4β-hydroxycholesterol (4β-HC), a known marker for CYP3A4 activity, were reduced in CD patients compared with UC patients and controls. These changes were more evident in ileal-resected CD patients. In contrast, serum plant sterols, markers for intestinal cholesterol absorption, were not significantly changed in all CD patients. These results showed that serum C4, FGF19, lathosterol and 4β-HC were good biomarkers for ileal malabsorption, which can be used for differential diagnosis of ileal diseases from jejunal or colorectal diseases.
