• duodenal ulcer
  • For eradication of Helicobacter pylori, treatment with pantoprazole and one of the following combinations of antibiotics: clarithromycin and amoxycillin or clarithromycin and metronidazole or amoxycillin and metronidazole is recommended in cases of duodenal ulcer and gastric ulcer with the objective of reducing the recurrence of duodenal and gastric ulcers caused by this microorganism (see Dosage and Administration).

  • An ulcer in the stomach is known as a gastric ulcer while that in the first part of the intestines is known as a duodenal ulcer. (wikipedia.org)
  • Duodenal ulcer pain would manifest mostly 2-3 hours after the meal, when the stomach begins to release digested food and acid into the duodenum. (wikipedia.org)
  • bicarbonate
  • The bicarbonate buffer system is an acid-base homeostatic mechanism involving the balance of carbonic acid (H2CO3), bicarbonate ion (HCO− 3), and carbon dioxide (CO2) in order to maintain pH in the blood and duodenum, among other tissues, to support proper metabolic function. (wikipedia.org)
  • HCO− is the concentration of bicarbonate in the blood [H2COis the concentration of carbonic acid in the blood This is useful in arterial blood gas, but these usually state pCO2, that is, the partial pressure of carbon dioxide, rather than H2CO3. (wikipedia.org)
  • Bismuth chelate may also stimulate the synthesis of prostaglandin and increase the secretion of the bicarbonate and mucus. (medicalrealm.net)
  • colonization
  • Thus, the available data suggest that colonization with H. pylori , particularly Cag A strains, may be protective against the more severe forms of GERD. (uptodate.com)
  • chronic
  • We describe the cases of three children with chronic active Helicobacter pylori gastritis and iron-deficiency anaemia without evidence of oesophagogastrointestinal bleeding. (springer.com)

  • It was identified in 1982 by Australian scientists Barry Marshall and Robin Warren, who found that it was present in a person with chronic gastritis and gastric ulcers, conditions not previously believed to have a microbial cause. (wikipedia.org)
  • However, H. pylori possibly plays a role only in the first stage that leads to common chronic inflammation, but not in further stages leading to carcinogenesis. (wikipedia.org)
  • metaplasia
  • A lower prevalence of Barrett's metaplasia and esophageal adenocarcinoma has also been described in individuals who were H. pylori positive [ 5,6 ]. (uptodate.com)
  • esophageal
  • A complete 24-hour profile of gastric acid secretion is best obtained during an esophageal pH monitoring study. (wikipedia.org)
  • Some studies suggested that H. pylori strains positive for Cag A (strains strongly associated with the development of corpus gastritis) may be particularly protective against the development of esophageal adenocarcinoma [ 7-9 ]. (uptodate.com)
  • urease
  • presented a comprehensive analysis of transcription at single-nucleotide resolution by differential RNA-seq that confirmed the known acid induction of major virulence loci, such as the urease (ure) operon or the cag pathogenicity island (see below). (wikipedia.org)
  • stomach acid
  • Even without bacterial overgrowth, low stomach acid (high pH) can lead to nutritional deficiencies through decreased absorption of basic electrolytes (magnesium, zinc, etc.) and vitamins (including vitamin C, vitamin K, and the B complex of vitamins). (wikipedia.org)
  • Chloride, sodium, potassium, zinc and/or iodine deficiency, as these elements are needed to produce adequate levels of stomach acid (HCl). (wikipedia.org)
  • The "Heidelberg test" is an alternative way to measure stomach acid and diagnose hypochlorhydria/achlorhydria. (wikipedia.org)
  • Ranitidine, sold under the trade name Zantac among others, is a medication that decreases stomach acid production. (wikipedia.org)
  • Famotidine, sold under the trade name Pepcid among others, is a histamine H2 receptor antagonist that inhibits stomach acid production. (wikipedia.org)
  • Treatment includes stopping smoking, stopping NSAIDs, stopping alcohol and giving medications to decrease stomach acid. (wikipedia.org)
  • By inhibiting the functioning of this transporter, the drug prevents formation of stomach acid. (wikipedia.org)
  • endoscopic
  • Currently modern trends in the treatment of gastric ulcer is aimed at developing methods that substitute surgical treatment is the creation of new medicines and technologies for minimally invasive endoscopic technique. (russianpatents.com)

  • endoscopy
  • Presents with abdominal pain and edema For practical purposes, gastric pH an endoscopy should be done in someone with suspected achlorhydria. (wikipedia.org)
