Overview
- Etiological classification of peptic ulcers:[1]
- Positive for Helicobacter pylori infection.
- Drug NSAID-induced.
- Helicobacter pylori and NSAIDs positive.
- H. pylori and NSAIDs negative (requires search for other causes).
- Approach of patients <55 years, depending of the H. pylori (H. pylori) prevalence (≥10%):[2]
- Test and treat for H. pylori using a validated noninvasive test and a trial of acid suppression if eradication is successful but symptoms do not resolve OR
- Empiric trial of acid suppression with a proton pump inhibitor (PPI) for 4-8 weeks.
Laboratory Findings
The methods of diagnostic testing for Helicobacter pylori can be classified into those that do and those that do not require endoscopy:[3]
- Breath testing (does not require EGD);*Direct culture from an EGD biopsy specimen;
- Direct detection of urease activity in a biopsy specimen;
- Measurement of antibody levels in blood (does not require EGD). It is still somewhat controversial whether a positive antibody without EGD is enough to warrant eradication therapy.
The possibility of other causes of ulcers, notably malignancy (gastric cancer) needs to be kept in mind. This is especially true in ulcers of the greater (large) curvature of the stomach; most are also a consequence of chronic H. pyloriinfection.
