Helicobacter pylori (H. pylori) infection is a gastrointestinal pathology caused by a spiral-shaped gram-negative bacterium that colonizes the mucous membrane of the stomach and duodenum. This infection is one of the most common in the world, affecting more than 50% of the population. There is convincing evidence of the connection between H. pylori and the development of chronic gastritis, peptic ulcers and even stomach cancer. The microorganism penetrates the mucous barrier, causing inflammation and tissue damage, which can lead to the progression of various gastrointestinal diseases. The effectiveness of H. pylori infection treatment largely depends on accurate diagnosis and an individual approach to each patient.
History of the disease and interesting historical facts
The first mention of the H. pylori bacterium was made in 1983, when Australian scientists Barry Marshall and Robin Warren isolated the microorganism from gastric mucosal biopsies. Until that time, gastritis and peptic ulcers were considered to be caused only by excessive secretion of gastric juice and stress. It was the discovery of Marsha and Warren that marked the beginning of a new era in gastroenterology, as a result of which they received the Nobel Prize in 2005. Scientists have proven that H. pylori not only colonizes the mucous membrane, but also causes inflammation, which can lead to serious gastrointestinal diseases. Since their discovery, approaches to the diagnosis and treatment of gastritis and peptic ulcers have changed significantly.
Epidemiology
According to statistics from the World Health Organization, H. pylori infection affects more than 50% of the world's population, especially in developing countries, where the prevalence rate can reach 80-90%. The infection is less common among children and adolescents, while the infection rate is significantly higher among adults, especially those over 50 years of age. Research shows that poor hygiene and repeated contact with contaminated food and water play an important role in the spread of H. pylori. High infection rates are also observed among people with low socioeconomic status, confirming the influence of the environment and living conditions on the risk of infection.
Genetic predisposition to this disease
Recent studies show that genetic predisposition plays an important role in the body’s ability to resist H. pylori infection. Research has found a link between certain gene polymorphisms, such as IL-10 and TNF-α, and the development of infectious processes, as they can affect the body’s immune response. Several genetic markers, such as HLA-DQ, have already been studied in the context of their role in predisposition to this infection. The presence of certain mutations can enhance the immune system’s response, leading to rapid progression of inflammatory processes in the stomach.
Risk factors for the development of this disease
There are a number of risk factors that contribute to H. pylori infection, including:
- Poor diet – consuming processed and fatty foods can increase the risk of developing gastritis.
- Poor sanitation – poor hygiene and the use of contaminated water contribute to the spread of bacteria.
- Heredity – having relatives with peptic ulcer disease or chronic gastritis increases the likelihood of infection.
- Stressful situations – Long-term stressful exposures can weaken the body's immune response.
- Hospitalization – while in medical institutions, the risk of contracting infections increases.
Diagnosis of this disease
Diagnosis of H. pylori infection is based on several methods, namely:
- Main symptoms: Chronic abdominal pain, dyspepsia, nausea, feeling full after eating.
- Laboratory tests: There are blood tests for antibodies and breath tests for urease.
- Radiological examinations: Using X-rays and endoscopy, changes in the gastric mucosa can be detected.
- Other types of diagnostics: Biopsy during endoscopy for microbiological analysis.
- Differential diagnosis: Other stomach diseases and the development of cancer should be excluded.
Treatment
Treatment of H. pylori infection is a multi-step process that includes:
- General treatment: Lifestyle changes, including diet and avoiding habits that negatively affect the stomach.
- Pharmacological treatment: Combination therapy with antibiotics and proton pump inhibitors.
- Surgical treatment: In extreme cases, gastric resection is possible for complicated forms of ulcers.
- Other types of treatment: Use of probiotics and supportive therapy.
List of medications used to treat this disease
Among the main drugs for the treatment of H. pylori infection are:
- Amoxicillin
- Clarithromycin
- Metronidazole
- Proton pump inhibitors (Omeprazole)
- If necessary – bismuth tripotassium dicitrate
Disease monitoring
Successful monitoring of patients with H. pylori includes:
- Control stages: Re-examination 4-8 weeks after completion of therapy.
- Forecast: Complete cure is achieved in most patients, but relapses are possible.
- Complications: It is important to monitor for possible development of H. pylori-related diseases, such as stomach cancer.
Age-related features of the disease
H. pylori infection can present differently depending on age group:
- Children: Often asymptomatic, manifestations of gastritis are possible.
- Adults: Severe symptoms, cough, dyspepsia.
- Elderly: Often asymptomatic, serious complications may occur due to weakened immune system.
Questions and Answers
- What is H. pylori? It is a bacterium that causes inflammation of the gastric mucosa and gastrointestinal diseases.
- What are the symptoms of infection? The main symptoms include abdominal pain, dyspepsia, nausea, loss of appetite.
- How is the diagnosis carried out? Diagnosis is made through blood tests, breath tests and endoscopy.
- How is H. pylori infection treated? Treatment includes antibiotics and proton pump inhibitors along with lifestyle changes.
- What to do in case of relapse? A re-examination and possibly a change in treatment plan or further consultations are necessary.
According to Dr. Oleg Korzhikov, if you have symptoms of stomach dysfunction, you should pay attention to your lifestyle and diet. “Take care of your health in advance; following simple hygiene rules, such as washing your hands and eating clean food, will significantly reduce the risk of infection,” he says. “If the disease has already been identified, it is important to strictly follow the treatment plan and monitor your health to avoid complications.”
