[Active chronic gastritis and Helicobacter pylori]

Area of Science:

• Gastroenterology
• Pathology
• Microbiology

Background:

• Active chronic gastritis (ACG) is a significant gastric condition.
• Two distinct forms of ACG exist: those associated with Helicobacter pylori (HP) and HP-negative cases.
• Understanding the distinct pathological features of each ACG type is crucial for effective management.

Purpose of the Study:

• To differentiate histological characteristics between HP-associated and HP-negative active chronic gastritis.
• To evaluate the efficacy of bismuth preparations and H2-blockers in treating ACG.
• To confirm the link between HP persistence and the severity of gastric inflammation.

Main Methods:

• Histological examination of gastric biopsies from 140 patients with ACG.
• Classification of ACG into HP-associated and HP-negative groups.
• Comparative analysis of inflammatory changes before and after treatment with bismuth and H2-blockers.

Main Results:

• HP-associated ACG showed characteristic inflammatory reactions in the foveal epithelium and lamina propria.
• HP-negative ACG was characterized by polymorphonuclear leucocyte infiltration and surface epithelium degeneration.
• Bismuth preparations led to a reduction in pronounced ACG stages.
• H2-blockers did not alter inflammatory changes, suggesting HP persistence drives inflammation.

Conclusions:

• Distinct histological patterns differentiate HP-associated and HP-negative active chronic gastritis.
• Bismuth-based therapies are effective in managing active chronic gastritis.
• The persistence of HP is directly linked to ongoing active inflammation in the gastric mucosa.
