Given that all eligible IBD patients were in active phase, diverse acute phase proteins, including C reaction protein (CRP), orosomucoid 1 (ORM1), orosomucoid 2 (ORM2), serum amyloid A1 (SAA1), serum amyloid A2 (SAA2), serum amyloid A2-serum amyloid A4 (SAA2-SAA4), ceruloplasmin (CP), haptoglobin (HP), and lipopolysaccharide binding protein (LBP), were further assessed (Fig. 3E). This evidence concerns the gene CRP and inflammatory bowel disease.
