[The pepsinogen-pepsin system in gastroduodenal pathology in children]

Area of Science:

• Biochemistry
• Gastroenterology
• Genetics

Background:

• The pepsinogen-pepsin system is crucial for gastric function.
• Morphological changes in the gastric mucosa correlate with this system.
• Understanding these changes aids in diagnosing gastroduodenal diseases.

Purpose of the Study:

• To investigate the relationship between the pepsinogen-pepsin system and gastric mucosal alterations.
• To identify potential genetic and biochemical markers for duodenal ulcers in children.
• To characterize the isoenzymic spectrum of pepsinogen-pepsin in various gastroduodenal conditions.

Main Methods:

• Examination of 98 children diagnosed with gastroduodenal diseases.
• Analysis of the pepsinogen-pepsin system.
• Assessment of isoenzymic spectrum variations.

Main Results:

• Changes in the pepsinogen-pepsin system correlate with the degree of gastric mucosal morphological alterations.
• Distinct isoenzymic patterns of pepsinogen-pepsin were observed across different gastroduodenal diseases.
• The study demonstrated the potential for distinguishing genetic and biochemical markers associated with duodenal ulcer in the pediatric population.

Conclusions:

• The pepsinogen-pepsin system serves as an indicator of gastric mucosal health.
• Isoenzymic analysis of pepsinogen-pepsin can aid in differentiating gastroduodenal diseases.
• Genetic and biochemical markers within this system show promise for early duodenal ulcer detection in children.
