What does "HP" mean in medicine?

HP (Helicobacter pylori) Helicobacter pylori disease is a spiral, slightly anaerobic bacteria, which has very strict requirements on growth conditions. 1983 was successfully isolated from the biopsy tissue of gastric mucosa of patients with chronic active gastritis for the first time, and it is the only known microbial species that can live in human stomach.

On 201710127 October, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was preliminarily sorted out for reference. Helicobacter pylori (infection) is on the list of carcinogens

Helicobacter pylori diseases include gastritis, digestive tract ulcer and lymphoproliferative gastric lymphoma caused by Helicobacter pylori infection. Gastric cancer is the poor prognosis of helicobacter pylori disease. Gastric cancer is one of the most common malignant tumors in the world, ranking second among the causes of cancer death. In China, about 6.5438+0.6 million people die of gastric cancer every year.

The prevention and control of gastric cancer has attracted increasing attention. Studies have pointed out that Helicobacter pylori lives in the pylorus of human stomach and is one of the most common bacterial pathogens. Most people in the world have been infected with Helicobacter pylori, and in some countries, almost 90% people have been infected with this bacterium. People are usually infected at a very young age, and people under the age of 5 reach 50%. This bacterial infection first causes chronic gastritis, and leads to gastric ulcer and gastric atrophy, and in severe cases develops into gastric cancer. According to statistics, among people infected with Helicobacter pylori for the first time, the incidence of atrophic gastritis and gastric cancer is higher, and there is a parallel relationship between Helicobacter pylori infection and gastric cancer mortality.

Helicobacter pylori is parasitic in gastric mucosa, and 67% ~ 80% of gastric ulcer and 95% of duodenal ulcer are caused by Helicobacter pylori. The common symptoms of patients with chronic gastritis and digestive tract ulcer are fullness, discomfort or pain in the upper abdomen after eating, often accompanied by other bad symptoms, such as belching, bloating, acid reflux and loss of appetite. Some patients may also have recurrent severe abdominal pain and a small amount of upper gastrointestinal bleeding. Accordingly, experts believe that early detection of Helicobacter pylori infection and timely and effective killing of Helicobacter pylori with antibiotics are of great significance to the prevention and control of gastric cancer.
