1. Were gastric biopsies taken for all patients and histological examination made
as a routine? What about the prevalence of atrophy and intestinal metaplasia? 
2. I am not worried about gastric polyps. Fundic gland polyps carry no
significance. I think we would like to know the correlation with GA and IM.
3. I am surprised at the low prevalence of peptic ulcers and gastric cancer in this
group of patients given that almost 100% have gastritis ( I presume this is
histologically proven).
