Etiopathogenetic principles and peptic ulcer disease classification

Area of Science:

• Gastroenterology
• Pathophysiology
• Pharmacology

Background:

• Peptic ulcer disease (PUD) arises from mucosal damage in the gastroduodenal environment.
• Historically, PUD was attributed solely to acid-peptic aggression, leading to acid-suppressive therapies.
• Current understanding emphasizes a disequilibrium between aggressive factors and mucosal defense mechanisms.

Purpose of the Study:

• To review the pathophysiology of peptic ulcer disease.
• To discuss the evolution of PUD treatment strategies.
• To highlight the need for novel approaches to bolster mucosal defenses.

Main Methods:

• Literature review of PUD pathogenesis and treatment.
• Analysis of historical and current therapeutic approaches.
• Discussion of emerging etiological factors and treatment challenges.

Main Results:

• Acid-peptic activity is a key aggressor, but impaired mucosal defense is crucial.
• Proton pump inhibitors (PPIs) effectively heal ulcers but do not prevent recurrence.
• Helicobacter pylori infection is the leading cause of PUD, with evolving eradication therapies.
• Drug-induced ulcers (NSAIDs, ASA) and idiopathic PUD remain significant concerns.

Conclusions:

• PUD results from a complex interplay of aggression and defense.
• Current therapies primarily manage symptoms and healing, not underlying defense.
• Further research into strengthening mucosal defense mechanisms is essential for PUD management.
