Serum endotoxin core antibody in CD patients stratified by GM-CSF Ab level and urine L:M ratio. Serum immunoglobulin A endotoxin core antibody (EndoCAb IgA) was determined by ELISA in CD patients (n = 27). A, CD patients were stratified by serum GM-CSF Ab concentration measured by ELISA. GM-CSF Ab Lo: CD patients with serum GM-CSF Ab concentration <1.6 μg/mL, GM-CSF Ab Hi: CD patients with serum GM-CSF Ab concentration ≥1.6 μg/mL. The means for each group were as indicated. *P< 0.0001 vs GM-CSF Ab Lo group. B, The relation between urine lactulose:mannitol ratio and serum EndoCAb IgA is shown. CD = Crohn disease; ELISA = enzyme-linked immunosorbent assay; GM-CSF = granulocyte macrophage-colony-stimulating factor.
