Assessment

Primary outcomes

1) Endoscopic findings: Kyoto gastritis classification and other findings like remnant oxyntic mucosa, status of antrum, mucous condition. Findings through indigo carmine dying method or NBI magnifying method. 2) Histological findings of each biopsy site, number of biopsies. 3) Blood sample results: titer of anti-parietal cell antibody, existence of anti-intrinsic factor antibody, PG1, PG 2, PG 1/2, RBC, Hb, Ht, MCV, WBC, platelet, VB12, folic acid, Fe, TSH, anti-thyroglobulin antibody, anti-glutamic acid decarboxylase antibody, blood sugar, HbA1C and others presumed to be related AIG. 4) Helicobacter pylori infection associated data :13C-UBT, anti H. pylori IgG antibody and H. pylori stool antigen. 5) Other associated clinical information, if available.

Results

Repeated incorrect treatments for H. pylori infection due to a false-positive result in 13C-urea breath test, ranked third among the basis for diagnosis of AIG. Associated gastric lesions were type 1 neuroendocrine tumor (11.4%), adenocarcinoma (9.8%). Corpus pan-atrophy was the most common appearance. Remnant oxyntic mucosa was found in 31.5% of the patients. Sticky adherent dense mucus and scattered minute whitish protrusions were observed in approximately 30% of the patients.
