Helicobacter heilmannii s.s. (H. heilmannii s.s.) is a species within the Helicobacter genus of Gram negative bacteria. [1] Helicobacter pylori (H. pylori) is by far the best known Helicobacter species primarily because humans infected with it may develop gastrointestinal tract diseases such as stomach inflammation, stomach ulcers, duodenal ulcers, stomach cancers of the non-lymphoma type, and ...
Gastritis caused by H. pylori infection is termed Helicobacter pylori induced gastritis, and listed as a disease in ICD11. [6] [7] More than 80% of individuals infected with the bacterium are asymptomatic and it has been postulated that it may play an important role in the natural stomach ecology. [17]
Once the diagnosis of H. pylori is confirmed, the first-line treatment would be a triple regimen in which pantoprazole and clarithromycin are combined with either amoxicillin or metronidazole. This treatment regimen can be given for 7–14 days. However, its effectiveness in eradicating H. pylori has been reducing from 90% to 70%. However, the ...
[10] [11] Infection with H. pylori is responsible for an estimated 89% of all gastric cancers and is linked to the development of 5.5% of all cases cancers worldwide. [13] [14] H. pylori is the only bacterium known to cause cancer. [15]
Helicobacter heilmannii sensu lato (i.e. H. heilmanni s.l.) is a grouping of non-H. pylori Helicobacter species that take as part of their definition a similarity to H. pylori in being associated with the development of stomach inflammation, stomach ulcers, [11] duodenum ulcers, [12] stomach cancers that are not lymphomas, and extranodal ...
The European Helicobacter Pylori Study Group published the Maastricht 2-2000 Consensus Report, suggesting a "test-and-treat" strategy for H. pylori in young patients without atypical symptoms. This strategy advocates the use of noninvasive testing to evaluate for H. pylori and simply treating if found, even in the absence of ulcer disease ...
Gastric outlet obstruction (GOO) is a medical condition where there is an obstruction at the level of the pylorus, which is the outlet of the stomach.Individuals with gastric outlet obstruction will often have recurrent vomiting of food that has accumulated in the stomach, but which cannot pass into the small intestine due to the obstruction.
Approximately half of those with peptic ulcers have an H. pylori infection. [3] Other causes include Mallory-Weiss tears, cancer, and angiodysplasia. [2] A number of medications are found to cause upper GI bleeds. [16] NSAIDs or COX-2 inhibitors increase the risk about fourfold. [16] SSRIs, corticosteroids, and anticoagulants may also increase ...
