Management
Eradication therapy
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 rate of eradication can be increased by doubling the dosage of pantoprazole or increasing the duration of treatment to 14 days. Quadruple therapy (pantoprazole, clarithromycin, amoxicillin, and metronidazole) can also be used. The quadruple therapy can achieve an eradication rate of 90%. If the clarithromycin resistance rate is higher than 15% in an area, the usage of clarithromycin should be abandoned. Instead, bismuth-containing quadruple therapy can be used (pantoprazole, bismuth citrate, tetracycline, and metronidazole) for 14 days. The bismuth therapy can also achieve an eradication rate of 90% and can be used as second-line therapy when the first-line triple-regimen therapy has failed

NSAIDs induced ulcers
NSAID-associated ulcers heal in 6 to 8 weeks provided the NSAIDs are withdrawn with the introduction of proton pump inhibitors (PPI). Bleeding
For those with bleeding peptic ulcers, fluid replacement with crystalloids is sometimes given to maintain volume in the blood vessels. Maintaining haemoglobin at greater than 7 g/dL (70 g/L) through restrictive blood transfusion has been associated with reduced rate of death. Glasgow-Blatchford score is used to determine whether a person should be treated inside a hospital or as an outpatient. Intravenous PPIs can suppress stomach bleeding more quickly than oral ones.
His symptoms disappeared after two weeks, but he took antibiotics to kill the remaining bacteria at the urging of his wife, since halitosis is one of the symptoms of infection. This experiment was published in 1984 in the Australian Medical Journal and is among the most cited articles from the journal. In 1997, the Centers for Disease Control and Prevention, with other government agencies, academic institutions, and industry, launched a national education campaign to inform health care providers and consumers about the link between H. pylori and ulcers. This campaign reinforced the news that ulcers are a curable infection and that health can be greatly improved and money saved by disseminating information about H. pylori.In 2005, the Karolinska Institute in Stockholm awarded the Nobel Prize in Physiology or Medicine to Marshall and his long-time collaborator Dr. Warren "for their discovery of the bacterium Helicobacter pylori and its role in gastritis and peptic ulcer disease." Marshall continues research related to H. pylori and runs a molecular biology lab at UWA in Perth, Western Australia. Some believed that mastic gum, a tree resin extract, actively eliminates the H. pylori bacteria. However, multiple subsequent studies have found no effect of using mastic gum on reducing H. pylori levels. Notes
