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) due to gastroduodenal diseases, which are more common in the pediatric
population [1,5]. Currently, there are more and more studies studying the association of
Helicobacter pylori infection with the development of food allergies. Helicobacter pylori
infection is manifested by various unexpected symptoms of extragastric diseases, one of
the most common being iron deficiency anemia [2,3].
In childhood, in addition to gastroduodenal pathology, there is a possibility of the
formation of iron deficiency and iron deficiency anemia, vitamin B12 deficiency, growth
retardation in adolescents, skin diseases, chronic urticaria, atopic dermatitis, and food
allergies against the background of Helicobacter pylori persistence [4].
One of the factors that is commonly associated with the features of clinical forms of
Helicobacter pylori-associated diseases is the genetic characteristic of the
microorganism, which determines its virulence
