A Case of Helicobacter heilmannii Gastritis in a Patient With Human Immunodeficiency Virus

Helicobacter heilmannii is an uncommon Helicobacter that is a cause of gastritis in humans similar to Helicobacter pylori (H. pylori). Treatment of H. heilmannii is not well studied, but traditional H. pylori regimens have shown success in case reports. Most case reports are in immunocompetent hosts, so little is known about the interplay between H. heilmannii and the immune system. We report a case of H. heilmannii infection in a patient with well-controlled human immunodeficiency virus infection who was treated with quadruple therapy (tetracycline, metronidazole, bismuth, and proton pump inhibitor) and had successful eradication of his infection.
