Gastric acid secretion using pentagastrin: dose-response studies
African Journal of Medicine and Medical Sciences
|September 1, 1982
Summary
Pentagastrin stimulation in Nigerians with duodenal ulcers showed an optimal dose of 6 micrograms/kg bodyweight. While this dose matches Caucasian recommendations, Nigerian males exhibited higher maximum acid output (MAO).
Area of Science:
- Gastroenterology
- Clinical Pharmacology
- Human Physiology
Background:
- Duodenal ulcer disease is a significant health concern.
- Gastric acid secretion plays a key role in ulcer pathogenesis.
- Understanding ethnic variations in gastric response is crucial for effective treatment.
Purpose of the Study:
- To determine the optimal pentagastrin dose for gastric acid stimulation in Nigerians.
- To compare gastric acid output in Nigerian duodenal ulcer patients and controls.
- To assess ethnic differences in gastric acid response to pentagastrin.
Main Methods:
- Twenty-five Nigerian participants (20 duodenal ulcer cases, 5 controls) were studied.
- Gastric stimulation was performed using pentagastrin at doses of 4, 6, 8, and 10 micrograms/kg bodyweight.
- Maximum acid output (MAO) was measured and analyzed based on sex and diagnosis.
Main Results:
- The optimal pentagastrin dose for maximal gastric acid response in Nigerian patients was 6 micrograms/kg bodyweight.
- The overall MAO at the optimal dose was 15.14 mEq/hr, with males (19 mEq/hr) showing higher output than females (12.50 mEq/hr).
- The optimal dose of 6 micrograms/kg bodyweight aligns with Caucasian studies, but MAO was notably higher in Nigerian males.
Conclusions:
- The optimal pentagastrin dose for gastric acid stimulation in Nigerians is 6 micrograms/kg bodyweight.
- Nigerian males exhibit a higher maximal acid output compared to females at the optimal pentagastrin dose.
- While the optimal pentagastrin dose is consistent across ethnic groups studied, significant sex-based differences in acid output exist within the Nigerian population.
