Common atopic history (15% (12/78) [78], 36% (24/67) [55], and 44% (20/45) [45]), peripheral blood eosinophilia (12% (9/78) [78], 16% (10/62) [55], 43% (6/14) [128], and 52% (13/25) [98]), and raised IgE titers (34% (12/35) [45], 60% (32/53) [55], and 86% (36/42) [34]) further corroborate Th2 involvement in patients with AIP (Supplemental Table S9).
