[Changes in the local proteinase-inhibitor system in children with chronic erosive gastritis]
Insights
In children with chronic erosive gastritis, an imbalance in the gastric proteinase-inhibitor system was found. This imbalance contributes to damaging changes in the gastric mucosa during disease flare-ups.
Area of Science:
- Gastroenterology
- Biochemistry
- Pathophysiology
Context:
- Chronic erosive gastritis in children is characterized by specific biochemical changes.
- Gastric juice analysis reveals alterations in proteinase and inhibitor activity during disease exacerbations and remissions.
Purpose:
- To investigate the role of the local proteinase-inhibitor system in the pathogenesis of chronic erosive gastritis in pediatric patients.
- To identify specific proteinase and antiproteinase activity patterns associated with disease activity.
Summary:
- In 26 children with chronic erosive gastritis, an unspecific proteinase-inhibitor potential was identified in gastric juice during exacerbation and incomplete remission.
- Elevated elastase and trypsin-like proteinase activity, coupled with decreased antiproteinase potential, indicates a significant imbalance in the local proteinase-inhibitor system.
- This imbalance and subsequent high proteinase activity are implicated in the destructive changes of the gastric mucosa, contributing to chronic inflammatory-and-destructive diseases.
Impact:
- The study highlights a critical pathogenetic mechanism in pediatric chronic erosive gastritis.
- Findings suggest that targeting the proteinase-inhibitor system could offer novel therapeutic strategies for managing destructive gastric mucosal diseases.
Abstract:
In 26 children presenting with chronic erosive gastritis, an unspecific proteinase-inhibitor potential was identified in the basal portion of the gastric juice in the period of exacerbation and incomplete remission. Revealed in the gastric content in the period of exacerbation was augmentation of the activity of elastase- and tripsinlike proteinases. In the period of remission, the indices have been shown to be lower but insignificantly, remaining significantly higher compared to those indices in the control group. There was a decrease in the antiproteinase potential in the period of exacerbation getting even more lowered during the period of incomplete remission. The findings secured suggest to us a manifest imbalance in the local proteinase-inhibitor system. A conclusion has been reached that exhaustion of the local inhibitor potential and ensuing high activity of unspecific proteinases result in destructive changes in the gastric mucosa, thus, having pathogenetic significance in the development of chronic inflammatory-and-destructive diseases.
