title: [Edematous syndrome revealing an exudative lymphocytic gastritis: efficacy of omeprazole].
abstract: Lymphocytic gastritis is characterized by intense lymphocytic infiltration of gastric epithelium. Excessive gastric protein loss is uncommon. We describe the case of a 49-year-old white woman suffering from generalized edema and abdominal pain. She had severe serum hypoproteinemia, hypoalbuminemia and hypogammaglobulinemia. There was no renal, cardiac or hepatic origin of protein loss, and no protein-losing enteropathy. Endoscopic examination showed diffuse varioliform gastritis and histology confirmed lymphocytic gastritis with > 30% intraepithelial lymphocytes without Helicobacter pylori. The protein loss stopped within two weeks of the beginning of omeprazole and extensive edema disappeared. Four years later, the patient was still free from edema. Inflammatory involvement of the gastric mucosa probably caused protein losing in this patient. Recognition of this exsudative gastropathy is important because long term remission is obtained with omeprazole.
