Who discovered the cure for Helicobacter pylori?
Barry Marshall and Robin Warren the two discoverers of this organism have been awarded with this year’s Nobel Prize.
How did Barry Marshall discover H. pylori?
In 1984, following a baseline endoscopy which showed a normal gastric mucosa, he drank a culture of the organism. Three days later he developed nausea and achlorhydria. Vomiting occurred and on day 8 a repeat endoscopy and biopsy showed marked gastritis and a positive H. pylori culture.
What is a unique characteristic of Helicobacter pylori?
H pylori is a gram-negative bacterium. It produces urease, has a spiral-like conformation, and is microaerophilic and motile because of the flagella. Flagella and urease are very important for its colonization of the gastric mucosa.
How do you beat H. pylori?
The options include:
- Antibiotics to kill the bacteria in your body, such as amoxicillin, clarithromycin (Biaxin), metronidazole (Flagyl), tetracycline (Sumycin), or tinidazole (Tindamax).
- Drugs that reduce the amount of acid in your stomach by blocking the tiny pumps that produce it.
Why do only some people with H. pylori develop ulcers?
Most infected people, however, do not develop ulcers. Why H. pylori doesn’t cause ulcers in every infected person is unknown. Most likely, infection depends on characteristics of the infected person, the type of H.
What are most ulcers caused by?
The most common causes of peptic ulcers are infection with the bacterium Helicobacter pylori (H. pylori) and long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Motrin IB, others) and naproxen sodium (Aleve).
What is the history of H. pylori?
H. pylori, a spiral-shaped bacterium that infects roughly half the world’s population, was first identified as a cause of stomach problems in the early 1980s. The discovery helped researchers link the H. pylori infection to conditions like gastritis, ulcers, and stomach cancer.
What happens to untreated H. pylori?
Both the acid and bacteria irritate the lining and cause an ulcer to form. If left untreated, a H. pylori infection can cause gastritis (inflammation of the lining of the stomach). Gastritis can occur suddenly (acute gastritis) or gradually (chronic gastritis).
How can I get rid of Helicobacter pylori?
H. pylori infections are usually treated with at least two different antibiotics at once, to help prevent the bacteria from developing a resistance to one particular antibiotic. Your doctor also will prescribe or recommend an acid-suppressing drug, to help your stomach lining heal.
