Helicobacter pylori : who is

Helicobacter pylori
Helicobacter pylori infection of the stomach and duodenum is one of the most common diseases in the world and requires prompt diagnosis and treatment.

What is Helicobacter pylori Helicobacter pylori

(Latin Helicobacter pylori.) - A bacterium that causes chronic inflammation of the gastric mucosa in humans (chronic gastritis).In addition, the micro-organism responsible for the development of gastric ulcer and duodenal ulcer.

presence of bacteria, scientists have also linked with the development of gastric cancer and a rare form of lymphocytic tumor - MALT-lymphoma.That is why it is so important to recognize the H. pylori infection and have her treatment or eradication if necessary.

Properties bacterium Helicobacter pylori Helicobacter pylori

has special ways of survival in harsh acidic environment of the stomach, alkalizing it.In addition, the bacteria stimulate the secretion of gastric and intestinal juice and compete with the natural inhabitants of the small intestine, causing goiter.All these

factors contribute to the inflammation and ulceration of the stomach and the intestine wall.

Infection occurs when consuming food or water, in which bacteria are present, as well as by contact, that is, from person to person.By the age of 60 microorganisms colonize the mucous membrane is almost always.

How common helicobacter infection

believed that around the world are infected with an average of about 2/3 of the people that can be called the H. pylori infection the most common disease in the world.

most often Helicobacter pylori is found in developing countries, with overcrowding and poor sanitary conditions in which people live.Statistics show that in countries with poor sanitation (India, South America, Africa) they are infected, about 90% of the adult population.In addition, in these countries, they are also often found in children and adolescents.

Typically, helicobacter infection is hidden and is not accompanied by any symptoms or symptoms.Nevertheless every sixth patient Helicobacter pylori infection leads to the development of ulcers on the mucosa of the stomach or duodenum.

How is the diagnosis of Helicobacter pylori infection

Modern medicine has a fairly simple methods accurate diagnosis of H. pylori infection.These include:

  • definition of antibodies in the blood;
  • urea breath test;
  • endoscopic biopsy of the mucous membrane;
  • determining antigens in stool.

detection of antibodies to Helicobacter pylori in the blood

blood test for antibodies to Helicobacter pylori makes it quick and easy to diagnose.Nevertheless blood of treated successfully with antibiotics human antibody to the bacteria may be present for many years after completion of therapy.Thus, blood tests are good diagnostic method, but should not be used to determine the efficacy of antibiotic treatment.

urea breath test for the detection of Helicobacter pylori

urea breath test is a safe and accurate method for detecting Helicobacter pylori in the stomach.The test is based on the ability of bacteria to degrade urea to ammonia and carbon dioxide, which is absorbed in the stomach, and excreted in expired air.

test technique is simple: to study the doctor asks the patient to swallow the capsule with a small amount of urea labeled with the security of radioactive material.After 10-20 minutes using a special instrument is held outside the fence of the sample and the analysis contained radioactive carbon dioxide.

positive test, that is, the presence of labeled carbon dioxide, says an active infection.After a short time after a course of antibiotics test becomes negative, indicating the absence of bacteria in the gastric mucosa.

Endoscopic biopsy for the detection of Helicobacter pylori

An accurate method for detecting Helicobacter pylori is an endoscopic examination, which allows you to identify inflammation and ulcers that accompany the infection.

During the procedure after oropharyngeal anesthesia local anesthetic doctor spends in the stomach, then into the duodenum a thin tube with a bulb at the end (endoscope).This allows you to examine the mucosa for any abnormalities, as well as to take a small sample of her tissue (biopsy).

piece of fabric is placed on a special slide that contains urea.In the presence of bacteria in the biopsy urea it begins to disintegrate, which is accompanied by a change in color and suggests the H. pylori infection.

Determination of antigens in stool

most modern method of diagnosis of infection Helicobacter pylori is the detection of bacterial antigens in stool samples.At the same positive analysis speaks of active infection.

This test also can be used to determine the effectiveness of antibiotic therapy after its completion.
