What is Helicobacter pylori (HP)?

Helicobacter pylori (HP) is a spiral bacterium colonizing gastric mucosa. It is implicated in the development of various gastrointestinal diseases, including gastritis, stomach, and duodenal ulcers, and it may increase the risk of gastric cancer.

Symptoms of infection

Helicobacter pylori (HP) is a bacterium that, when it infects the gastric mucosa, can cause various symptoms. Most infected individuals will not show pronounced symptoms, but in some cases, the bacterium can cause issues associated with stomach diseases. These symptoms result from the inflammation and damage to the gastric mucosa that the bacterium can cause:

• Pain or discomfort in the upper part of the stomach or abdomen
• Nausea and vomiting
• Loss of appetite
• Frequent belching
• Stomach bloating
• Feeling full quickly during meals
• Unexplained weight loss
• Anemia caused by internal bleeding
• Black or tarry stools (a sign of bleeding in the stomach)

Recognizing these symptoms and consulting with a doctor is crucial for early detection and treatment of the infection. If a person has any of these symptoms, especially if they are long-lasting or worsening, they should seek medical help.

How can people become infected with Helicobacter pylori?

People can become infected with Helicobacter pylori in several ways:

• Stomach-to-mouth: This occurs when microorganisms from an infected person’s stomach reach another person’s mouth. This can happen by sharing food or drinks with an infected person.
• Mouth-to-mouth: Direct contact between the oral cavities of two people can transmit the bacterium, especially if one person has an active infection. Transmission methods include sharing eating utensils, glasses, or even kissing.
• Feces-to-mouth: The bacterium can be transmitted if a person consumes food or water contaminated with the feces of an infected person. This often results from poor hygiene, such as inadequate hand washing after using the toilet.

The risk of infection can be reduced by adhering to basic hygiene measures, such as regular and thorough hand washing.

What is the Helicobacter pylori Ag in stool analysis?

The Helicobacter pylori Ag in stool test is a non-invasive diagnostic method used to detect the presence of Helicobacter pylori (HP) antigens directly in patient stool samples. This test is particularly useful because of its simplicity and avoids the need for more invasive procedures such as endoscopy.

When the Helicobacter pylori bacterium is present in the stomach, it releases specific proteins (antigens). These antigens are eliminated from the body through the stool. The test detects these antigens in a stool sample using specific antibodies.

When is the Helicobacter pylori Ag in stool test done?

The Helicobacter pylori Ag in stool analysis is usually performed in the following situations:

• When a patient has symptoms suggestive of an infection in the stomach or duodenum, the doctor may recommend this analysis as a non-invasive way to determine the presence of Helicobacter pylori.
• After a patient has been diagnosed with Helicobacter pylori infection and has completed antibiotic treatment to eradicate the bacterium, the test confirms that the infection has been successfully cured.
• This is for patients who avoid or cannot tolerate endoscopy and children or older individuals for whom endoscopy may be problematic.
• In some environments where the prevalence of Helicobacter pylori is high, stool testing can be useful for mass screening and identifying individuals who need treatment.

Sample collection

For testing, a stool sample about the size of a hazelnut is needed and should be placed in an appropriate container. The sample must be fresh and quickly transported to the laboratory.

Test results

The result of the Helicobacter pylori in stool test provides key information about the presence of this bacterium in the digestive tract.

• A positive result indicates an active Helicobacter pylori infection.
• A negative result usually means that the person is not currently infected.

If the results of the Helicobacter pylori in stool test do not match the patient’s clinical picture, further testing is recommended. Common alternatives include:

• Urea breath test
• Serological test that identifies IgG antibodies
• Serological test that identifies IgA antibodies

Due to the specific nature of Helicobacter pylori, this bacterium is difficult to culture on standard nutrient media, which is why the cultivation method is rarely used in conventional diagnostics. Instead, experts rely on more precise methods to confirm its presence.
