Management of Refractory Gastritis

Evaluation and Optimization of PPI Therapy

The American Gastroenterological Association recommends switching to a higher potency PPI such as esomeprazole 20-40mg or rabeprazole 20-40mg twice daily for patients with gastritis not responding to lansoprazole 1, 5
Ensure proper timing of PPI administration, taking it 30 minutes before meals for optimal efficacy, as suggested by the American College of Gastroenterology 4, 5
Evaluate for Helicobacter pylori infection, a common cause of persistent gastritis despite PPI therapy, as recommended by the American Gastroenterological Association 1, 2

The American College of Gastroenterology recommends using one of the following empiric therapies for H. pylori positive patients: Bismuth quadruple therapy for 14 days or Rifabutin triple therapy for 14 days 1, 2
Avoid clarithromycin triple therapy unless local susceptibility testing confirms >90% effectiveness, as suggested by the Infectious Diseases Society of America 1, 2

Consider adding H2-receptor antagonists for nighttime symptoms, though be aware of tachyphylaxis with prolonged use, as recommended by the American Gastroenterological Association 5, 8
Alginate antacids may be effective for breakthrough symptoms, particularly post-prandial symptoms, as suggested by the American College of Gastroenterology 5, 8

Implement aggressive lifestyle modifications, including weight management if applicable, as recommended by the American Heart Association 9, 5
Avoid meals within 3 hours of bedtime and elevate the head of the bed for patients with nighttime symptoms, as suggested by the American College of Gastroenterology 4, 5

If symptoms persist despite optimized PPI therapy and H. pylori eradication, consider endoscopy with biopsy, as recommended by the American Gastroenterological Association 7, 6
High-resolution manometry and 24-hour pH-impedance monitoring may be necessary to evaluate for alternative diagnoses or mechanisms of persistent symptoms, as suggested by the American College of Gastroenterology 9, 6
