Esophageal IgG4: Clinical, Endoscopic, and Histologic Correlations in Eosinophilic Esophagitis

Conclusions: Our study suggests IgG4 is not a consistent finding of EoE at disease diagnosis. Although IgG4 staining was specific for EoE, it had a poor sensitivity with positive staining in only 48% of EoE patients. Further studies are warranted to fully elucidate the role of IgG4 in EoE.
