Abstract

Sera from patients with Crohn's disease and control were analyzed by an enzyme-linked immunosorbent assay based on the Mycobacterium paratuberculosis-specific recombinant polypeptide a362. Anti-a362 immunoglobulin G (IgG) (P < 0.05) and IgA (P < 0.001) titers were higher in patients with Crohn's disease than in controls. A monomodal Gaussian distribution of anti-a362 IgA levels were found for controls, and a bimodal distribution was found for patients with Crohn's disease. An M. paratuberculosis etiology is suggested for the 36% of patients with Crohn's disease who had an anti-a362 IgA level higher than that of controls.

摘要

采用基于副结核分枝杆菌特异性重组多肽a362的酶联免疫吸附测定法,对克罗恩病患者和对照者的血清进行分析。克罗恩病患者的抗a362免疫球蛋白G(IgG)(P<0.05)和IgA(P<0.001)滴度高于对照者。对照者的抗a362 IgA水平呈单峰高斯分布,而克罗恩病患者呈双峰分布。对于36%抗a362 IgA水平高于对照者的克罗恩病患者,提示其病因与副结核分枝杆菌有关。
