Diagnosis and Treatment of Helicobacter Pylori
Helicobacter pylori (H. pylori) is a spiral-shaped bacterium that colonizes the human digestive system, particularly the stomach and duodenum. This bacterium is recognized as the main cause of chronic gastritis (inflammatory stomach disease) and is often associated with peptic ulcers and certain types of stomach cancer. H. pylori is a very widespread bacterium, and it is estimated that it is present in more than half of the world's population. The infection is most commonly transmitted through oral-oral or fecal-oral routes, usually during childhood. The bacterium can establish a long-term presence in the mucosa of the stomach or duodenum, where it causes inflammation and tissue damage.
WHAT ARE THE SYMPTOMS OF H. PYLORI INFECTION?
Symptoms of Helicobacter pylori infection can vary, but many infected people have no visible symptoms. Symptoms may include: pain or discomfort in the abdomen, nausea, vomiting, loss of appetite, unexplained weight loss, heartburn, or belching. In some cases, H. pylori can lead to the development of ulcers in the stomach or duodenum, which can cause pain and complications such as bleeding or perforation.
HOW IS THE DIAGNOSIS OF H. PYLORI MADE?
The diagnosis of H. pylori infection is usually made by taking tissue samples (biopsy) from the stomach during an endoscopy or by testing breath or stool for the presence of bacteria. Treatment is usually carried out with a combination of antibiotics (to kill the bacteria) and proton pump inhibitors (to reduce the acidity of gastric juice).
HOW IS IT TREATED?
It is important to treat H. pylori infection to reduce the risk of complications and improve digestive health. Treatment of Helicobacter pylori infection usually includes a combination of several antibiotics and proton pump inhibitors (PPIs). Triple therapy: The most common first choice is triple therapy, which consists of two antibiotics and one PPI. Typically, a combination of clarithromycin (a macrolide antibiotic) and amoxicillin (a penicillin antibiotic) is used along with a PPI such as omeprazole, lansoprazole, or pantoprazole. This combination is usually taken for 10 to 14 days. Quadruple therapy: If there is resistance to clarithromycin or failure of triple therapy, quadruple therapy is used. This therapy includes two types of antibiotics (usually amoxicillin and metronidazole) along with a PPI and bismuth. This combination is also taken for 10 to 14 days. Other combinations: In case of ineffectiveness or resistance to the aforementioned treatment regimens, other combinations of antibiotics such as levofloxacin, tetracycline, or rifabutin can be applied, in combination with a PPI. It is important to adhere to the recommended treatment regimen and take medications in prescribed doses and regular intervals. The effectiveness of the treatment can be checked by breath tests, stool tests, or taking tissue samples from the stomach after the therapy is completed. During treatment, it is also important to avoid irritating substances such as alcohol, coffee, spicy foods, or tobacco smoke, as they can worsen symptoms and hinder recovery. It is important to note that Helicobacter pylori bacteria can develop resistance to certain antibiotics. If the first therapy is not effective, it is important to consult a doctor to find an appropriate alternative treatment regimen.
