Summary
Acute doxycycline can cause esophageal injury, including esophagitis and ulcers. Gastroesophageal reflux due to lower esophageal sphincter dysfunction is the primary cause of this doxycycline side effect.
Area of Science:
- Gastroenterology
- Pharmacology
Background:
- Doxycycline is a widely used antibiotic with potential gastrointestinal side effects.
- Esophageal injury is a recognized, though infrequent, complication of oral doxycycline therapy.
Observation:
- This study presents four cases of acute doxycycline-induced esophageal mucosal injury.
- The observed injuries included acute catarrhal doxycycline esophagitis and acute doxycycline ulcer.
Findings:
- The primary pathogenetic mechanism identified is gastroesophageal and duodenogastric reflux.
- This reflux is often a consequence of functional failure of the lower esophageal sphincter.
Implications:
- Understanding the mechanism of doxycycline esophagitis is crucial for prevention and management.
- Prophylactic measures and treatment strategies for doxycycline-induced esophageal injury should address reflux and sphincter function.
