Marked Hypergastrinemia and Extreme Erythrocyte Sedimentation Rate Elevation in Autoimmune Atrophic Gastritis with Severe Iron Deficiency Anemia: A Case Report. [PDF]

Clin Case Rep
ABSTRACT Autoimmune atrophic gastritis causes loss of oxyntic glands, reduced acid secretion, compensatory hypergastrinemia, and impaired iron and vitamin B12 absorption. A 46‐year‐old woman with minimal gastrointestinal symptoms had fasting serum gastrin > 1800 ng/L, an erythrocyte sedimentation rate of 109 mm/h, hemoglobin 8.2 g/dL, and microcytosis.
