Reviewer’s report
Title: 
Immunoglobulin G4-associated autoimmune hepatitis with peripheral
blood eosinophilia: a case report.
Version: 
0 
Date: 
24 Jul 2020
Reviewer's report:
The authors report an interesting case report. 
Major comments
1) Since this patient had eosinophilia, you should exclude acute hepatitis and
other diseases. Ex, HEV, HIV, CMV, EBV, parasites, drug-induced liver injury,
monoclonality of IgG (M-protein), IgA, IgM.
2) Pathological findings: Chronic hepatitis with zonal and bridging necrosis or
broad collapse
3) As the authors discussed , most of IgG4-AIH patients had other IgG4-related
disease. However, this and another (Umemura et al. Hepatology, 52: 389-390 )
cases had only hepatitis.
Minor comments
1) Background line 5: chroni c should be as chronic.
2) Background lines 9-12: IgG4-asscoiated AIH is firstly used by Umemura et al.
GUT 2007;56:1471-1472., not this review (ref 4). You need to cite a first case
report.
