H. pylori-Associated Peptic Ulcer Disease Management

Diagnosis and Initial Assessment

The American Gastroenterological Association recommends assessing for alarm symptoms such as weight loss, progressive dysphagia, recurrent vomiting, evidence of GI bleeding, and family history of gastric cancer in patients with suspected peptic ulcer disease 1, 2
A detailed history focusing on the duration and character of pain, as well as NSAID use, is crucial in diagnosing peptic ulcer disease 1
Physical examination, including vital signs and abdominal examination, should be performed to assess for epigastric tenderness and other signs of peptic ulcer disease 3, 4

The American College of Gastroenterology recommends using the urea breath test (13C-UBT) as the preferred first-line test for diagnosing H. pylori infection 7, 8, 9
If the urea breath test is unavailable, the stool antigen test can be used as an alternative 9
Validated laboratory serology can be used if the patient is unable to stop taking PPIs, but it must have >90% sensitivity and specificity 8, 9

The American Gastroenterological Association recommends treating H. pylori infection with a 14-day course of bismuth quadruple therapy or concomitant therapy (non-bismuth quadruple therapy) 3, 8
Patient education on taking medications at the start of meals, completing the full 14-day course, avoiding NSAIDs, and scheduling a follow-up appointment for test of cure is essential 6

The American College of Gastroenterology recommends performing a test of cure 6-8 weeks after completion of treatment, using the urea breath test (13C-UBT) or stool antigen test 3, 9
If the test of cure is positive, a second-line eradication therapy with a different antibiotic regimen should be prescribed 6

Eradication of H. pylori infection can reduce the risk of gastric cancer by halting the progression to atrophic gastritis and reduce the risk of ulcer recurrence 4, 10
