Helicobacter pylori duodenal colonization is a strong risk factor for the development of duodenal ulcer.
Pietroiusti A, et al. Aliment Pharmacol Ther 2005. PMID 15801926 Free article.
No patients received eradication during 1 year follow-up. At this time, endoscopy was repeated and the incidence of duodenal ulcer was assessed. ...Duodenal ulcer developed in 12 (22.6%) patients with duodenal colonization and in two (1.6%) without duodenal colonization (odds ratio for duodenal ulcer: 6.29, 95% confidence intervals 2.44-17.45). ...

Duodenal ulcer disease.
Tytgat GN. Eur J Gastroenterol Hepatol 1996 - Review. PMID 8864685
An overview is given of the pathogenic mechanisms involved in Helicobacter pylori-associated duodenal and gastric ulceration. ...Finally the questions about ulcer disease which remain unanswered are summarized....

Effect of Helicobacter pylori eradication on the ulcer recurrence rate after simple closure of perforated duodenal ulcer: retrospective and prospective randomized controlled studies.
Kate V, et al. Br J Surg 2001 - Clinical Trial. PMID 11488789
BACKGROUND: The possible advantage of eradication of Helicobacter pylori in patients with perforated duodenal ulcer is unknown. ...CONCLUSION: Eradication of H. pylori after simple closure of a perforated duodenal ulcer should reduce the incidence of residual and recurrent ulcers....

Helicobacter pylori colonization density and gastric acid output in non-ulcer dyspepsia and duodenal ulcer disease.
Mullins PD and Steer HW. Helicobacter 1998. PMID 9631305
A quantitative assessment of H. pylori colonization density in biopsies from five sites of the gastroduodenum in the active ulcer group, and from the antrum in inactive duodenal ulcer and non-ulcer groups. ...There were negative correlations between antral H. pylori colonization density and PAO in the active duodenal ulcer (r - 0.7449, p < 0.01) and non-ulcer (r - 0.5837, p < 0.1) groups but not in the inactive duodenal ulcer group (r - 0.1869, p > 0.2). ...

Acute perforated duodenal ulcer is not associated with Helicobacter pylori infection.
Reinbach DH, et al. Gut 1993. PMID 8244099 Free PMC article.
In 51 of the perforated duodenal ulcer patients 14C-urea breath tests were also performed 4-10 weeks after surgery and this confirmed that only 49% were positive for H pylori. ...Regular non-steroidal anti-inflammatory drug (NSAID) use was common in both those with (44%) and without (45%) H pylori. In conclusion, the lack of association of acute perforated duodenal ulcer and H pylori infection suggests that perforated duodenal ulcer has a different pathogenesis from chronic duodenal ulcer disease, and that the first should not be regarded simply as a complication of the second....

Duodenal ulcer treated with Helicobacter pylori eradication: seven-year follow-up.
Forbes GM, et al. Lancet 1994 - Clinical Trial. PMID 7905095
The long-term benefits of Helicobacter pylori-eradication treatment (HET) in H pylori-associated duodenal ulcer are unclear. ...The reduction of duodenal ulcer relapse obtained from H pylori eradication in H pylori-associated duodenal ulcer extends to at least 7 years after treatment, and is likely to be due to freedom from H pylori infection. ...

Perturbations in gastric physiology in Helicobacter pylori duodenal ulcer: are they all epiphenomena?
Graham DY and Dore MP. Helicobacter 1997 - Review. PMID 9432354
H. pylori is inhibited by bile, yet can thrive in the duodenal bulb of duodenal ulcer patients. Glycine-conjugated bile acids are precipitated by acid; thus, any mechanism that would increase the duodenal acid load may remove the inhibitory bile and allow unrestrained growth of H. pylori. CONCLUSION: These data and speculations offer one possible explanation for why duodenal ulcer occurs in only some people--those with high acid secretion--and suggest that the combination of high duodenal acid load and H. pylori infection is sufficient to result in duodenal ulcer disease....

Relationship between Helicobacter pylori infection and gastric metaplasia in the duodenal bulb in the pathogenesis of duodenal ulcer.
Futami H, et al. J Gastroenterol Hepatol 1999. PMID 10029290
METHODS: Duodenal and gastric biopsy specimens were obtained from H. pylori-positive patients with duodenal ulcer, gastric ulcer or chronic gastritis. ...RESULTS: The prevalence and extent of gastric metaplasia and the amount of H. pylori in the duodenal bulb in patients with duodenal ulcer were much higher than in patients with gastric ulcer or chronic gastritis. ...

Standard treatment for Helicobacter pylori infection is suboptimal in non-ulcer dyspepsia compared with duodenal ulcer in Chinese.
Wong WM, et al. Aliment Pharmacol Ther 2005. PMID 15644048 Free article.
AIM: The aim of this study was to study the efficacy of triple therapy for H. pylori infection in patients with duodenal ulcer vs. patients with non-ulcer dyspepsia. ...Clarithromycin resistance rate was higher in patients with non-ulcer dyspepsia than those with duodenal ulcer (14% vs. 6%, P = 0.015). ...

Altered cytokine expression in Helicobacter pylori infected patients with bleeding duodenal ulcer.
Milic L, et al. BMC Res Notes 2019. PMID 31092295 Free PMC article.
OBJECTIVE: Peptic ulcer disease is a condition in which an important role has infection with H. pylori. The most common complication of peptic ulcer is bleeding. The presence of H. pylori triggers local and systemic cytokine signaling which may affect processes such as healing, gastric or duodenal rupture, and carcinogenesis. ...
