We measured serum pepsinogen I (sPG-I) in 269 patients undergoing upper GI endoscopy and then classified by endoscopic diagnosis, gastric mucosal histology, and smoking habit. Both ulcer-free and duodenal ulcer smokers had significantly higher sPG-I levels than their non-smoking controls. In contrast, sPG-I values were not different in smokers and non-smokers with gastric ulcer. In ulcer-free smokers the overall increase in sPG-I simply reflected the high prevalence of patients with superficial gastritis and elevated sPG-I levels. Conversely, in duodenal ulcer smokers the increase in sPG-I, which was related to the number of cigarettes smoked daily, was not an epiphenomenon of concomitant gastritis. The smoking-induced increase in sPG-I in duodenal ulcer is proposed to reflect an augmented pepsin secretory capacity, which can be of aetiologic significance in the association between cigarette smoking and duodenal ulcer.

Abstract

We measured serum pepsinogen I (sPG-I) in 269 patients undergoing upper GI endoscopy and then classified by endoscopic diagnosis, gastric mucosal histology, and smoking habit. Both ulcer-free and duodenal ulcer smokers had significantly higher sPG-I levels than their non-smoking controls. In contrast, sPG-I values were not different in smokers and non-smokers with gastric ulcer. In ulcer-free smokers the overall increase in sPG-I simply reflected the high prevalence of patients with superficial gastritis and elevated sPG-I levels. Conversely, in duodenal ulcer smokers the increase in sPG-I, which was related to the number of cigarettes smoked daily, was not an epiphenomenon of concomitant gastritis. The smoking-induced increase in sPG-I in duodenal ulcer is proposed to reflect an augmented pepsin secretory capacity, which can be of aetiologic significance in the association between cigarette smoking and duodenal ulcer.
