Cigarette smoking, gastric acid secretion, and serum pepsinogen I concentrations in duodenal ulcer patients
View abstract on PubMed
Summary
This summary is machine-generated.Acute smoking does not affect basal gastric secretion in duodenal ulcer patients. However, chronic heavy smoking is linked to increased gastric acid and pepsinogen secretion, suggesting enhanced cell function or mass.
Area Of Science
- Gastroenterology
- Internal Medicine
- Oncology
Background
- Cigarette smoking is associated with duodenal ulcer disease.
- The precise mechanism linking smoking and duodenal ulcers remains unclear.
- Understanding smoking's impact on gastric physiology is crucial for ulcer management.
Purpose Of The Study
- To evaluate the effect of acute smoking on basal gastric secretion in smokers with active duodenal ulcers.
- To investigate the impact of chronic smoking on gastric secretory capacity in patients with duodenal ulcers and non-ulcer dyspepsia.
- To assess pentagastrin-stimulated gastric acid secretion and serum pepsinogen I (PG I) levels in relation to smoking habits.
Main Methods
- Assessed basal gastric acid and pepsin secretion in 10 smokers with duodenal ulcers after smoking four cigarettes.
- Measured fasting serum PG I and gastrin concentrations in the same group.
- Evaluated pentagastrin-stimulated gastric acid secretion and fasting serum PG I in 136 duodenal ulcer patients and 90 non-ulcer dyspepsia controls, categorizing them by smoking status (heavy smokers vs. non-smokers).
Main Results
- Acute smoking did not alter basal gastric secretion, serum PG I, or gastrin levels in smokers with duodenal ulcers.
- Habitual heavy smokers with duodenal ulcers or non-ulcer dyspepsia exhibited significantly higher pentagastrin-stimulated acid secretion and fasting serum PG I concentrations compared to non-smokers.
- These findings indicate a differential effect of acute versus chronic smoking on gastric secretory function.
Conclusions
- Acute cigarette smoking does not acutely impact gastric acid and pepsin secretion in individuals with duodenal ulcers.
- Chronic heavy smoking appears to be associated with either an increased parietal and chief cell mass or enhanced secretory capacity in the stomach.
- The study suggests a long-term physiological adaptation in heavy smokers that may contribute to their risk of duodenal ulcer disease.
