Finally, plasma CgA was found to be increased in inflammatory bowel disease [28], which, however, can be ruled out by means of the clinical picture (e.g., bloody diarrhea, abdominal pain in the lower quadrants), radiologic (e.g., ultrasound, computer tomography scan, magnetic resonance), and endoscopic (e.g., colonoscopy) examinations. This evidence concerns the gene CGA and inflammatory bowel disease.
