Helicobacter pylori

Helicobacter pylori, often referred to as H.pylori, is a type of spiral-shaped bacteria that can survive in the acidic environment of the human stomach. It plays a significant role in causing conditions such as peptic ulcers, atrophic gastritis, and even gastric cancer.

It's important to note that more than half of the world's population is infected with H.pylori. In developing countries, people tend to acquire this infection during childhood, while in developed countries, it usually happens later in life. Surprisingly, during population research, H.pylori was found in almost 80% of people aged 17 to 99, with an average age of 54.

Interestingly, most individuals with H.pylori infection (around 80%) don't experience any noticeable symptoms. However, a small percentage (1-2%) of those carrying this infection may develop gastric cancer later in life. Therefore, it's crucial to identify those at higher risk in a timely manner.

To treat H.pylori infection, a combination of drugs, typically including two antibiotics, is required for a period of 7 to 14 days. It's worth noting that the initial treatment may not always be successful.

Moreover, there's a risk of adverse events associated with antibiotic treatment, so careful selection of candidates for treatment is essential. Researchers are also working on developing therapeutic vaccines for H.pylori, but these are not yet available.
