Objective To evaluate the prevalence of autoimmune gastritis in patients with histologically proven nonalcoholic steatohepatitis (NASH). Methods A total of 33 patients with NASH and 143 patients with chronic liver disease (66, 24, 22, 10, 1, and 21 patients with hepatitis C, hepatitis B, autoimmune hepatitis/primary biliary cholangitis, non-B/non-C hepatitis, fatty liver, and alcoholic disease, respectively) who underwent upper gastrointestinal endoscopy between January 2013 and August 2016 were retrospectively assessed to determine the prevalence of autoimmune gastritis. The clinical characteristics of these patients with NASH and autoimmune gastritis were examined, and the clinical characteristic and biomarkers were compared between patients with NASH with and without autoimmune gastritis. Results Six of the 33 patients with NASH (19.4%) were diagnosed with autoimmune gastritis. The prevalence of autoimmune gastritis was higher in patients with NASH than in those with other chronic liver diseases [4/143 (2.8%), p=0.002]. All six patients with NASH and autoimmune gastritis exhibited high serum gastrin levels; five of the patients were positive for anti-parietal cell antibodies, and one was negative for anti-parietal cell antibodies but positive for intrinsic factor antibody. Furthermore, 1 patient presented with iron-deficiency anemia (hemoglobin <11 g/dL), but none developed pernicious anemia. Endocrine cell micronests were found in four patients. Patients with NASH and autoimmune gastritis tended to be older with lower ferritin levels than the other patients. Conclusion The prevalence of NASH with concomitant autoimmune gastritis was high, highlighting the need for upper endoscopy for the diagnosis of autoimmune gastritis and gastric malignancies.

An 80-year-old man with chronic renal failure and a splenorenal shunt was admitted because of progressive anemia. Gastrointestinal endoscopy revealed bleeding from a gastric antral vascular ectasia (GAVE). Despite treatment with argon plasma coagulation and blood transfusions on multiple occasions, anemia caused by GAVE bleeding recurred frequently. The GAVE improved after splenorenal shunt embolization, and the patient did not require further blood transfusions for anemia. In this case, we inferred that some humoral factor (e.g., gastrin) in the portal blood caused the GAVE.
