摘要：
Identification of autoantibodies associated with Crohn's disease useful in diagnosis and management using an innovative protein array technology, namely nucleic acid programmable protein arrays (NAPPA) and applications relating thereto. Overall, reactivity of IgG autoantibodies was stronger than that of IgA autoantibodies; however, IgA autoantibodies showed greater differential reactivity between cases and controls. Four IgA autoantibodies against SNRPB, PRPH, PTTG1 and SNAI1 were newly identified with sensitivities above 15% at 95% specificity, among which anti-SNRPB-IgA had the highest sensitivity of 24.0%. Autoantibodies associated with specific disease subtypes were also found.
