Helicobacter pylori is a newly discovered gram-negative bacterium that lives in the human stomach and duodenum. Infection with this organism is strongly associated with type B antral gastritis and with peptic ulcer disease. Recent evidence from human volunteer studies, therapeutic trials with antimicrobial agents, and experiments with animal models indicates that H. pylori plays an etiologic role in the pathogenesis of type B gastritis. Gastric metaplasia is observed in virtually all patients with duodenal ulceration and may be the target tissue for these bacteria in the duodenum. Patients in whom H. pylori can no longer be identified after ulcer therapy remain in remission for significantly longer than do patients in whom the organism can be found. The data concerning an etiologic role of H. pylori in duodenal ulcer are suggestive but not yet conclusive. Present antimicrobial therapy can suppress but usually cannot eliminate H. pylori.
This research output has an Altmetric Attention Score of 12. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 June 2026.
All research outputs
#3,668,461
of 33,666,858 outputs
Outputs from Journal of Infectious Diseases
#3,304
of 17,889 outputs
Outputs of similar age
#1,120
of 22,286 outputs
Outputs of similar age from Journal of Infectious Diseases
#11
of 63 outputs
Altmetric has tracked 33,666,858 research outputs across all sources so far. Compared to these this one has done well and is in the 88th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 17,889 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 16.6. This one has done well, scoring higher than 79% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 22,286 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 93% of its contemporaries.
We're also able to compare this research output to 63 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 76% of its contemporaries.
