Abstract:
Helicobacter pylori infection is one of the most widespread infections on the globe.
Helicobacter pylori infection is involved in the development of iron deficiency anemia (IDA) against
the background of gastroduodenal diseases, which are more common in the pediatric population [1,5].
Currently, there are increasingly more studies studying the connection between Helicobacter pylori
infection and the development of food allergies. Helicobacter pylori infection manifests itself in
various unexpected symptoms of extragastric diseases, one of the most common is iron deficiency
anemia [2,3].
In childhood, in addition to gastroduodenal pathology, there is a possibility of developing iron
deficiency and iron deficiency anemia, vitamin B12 deficiency, growth retardation in adolescents, skin
diseases, chronic urticaria, atopic dermatitis, food allergies against the background of persistence of
Helicobacter pylori [4].
One of the factors with which the characteristics of clinical forms of Helicobacter pylori-associated
diseases are usually associated is the genetic characteristics of the microorganism, which determines
its virulence.
