UNLABELLED: To elucidate whether serum levels of pepsinogens are associated with the occurrence of gastrointestinal adverse events induced by amino-bisphosphonates (amino-BP), the serum levels of pepsinogen were measured in amino-BP users. Our results indicate that measurement of pepsinogen I is useful in predicting gastric distress induced by amino-BP in osteoporosis. INTRODUCTION: To elucidate whether serum levels of pepsinogens are associated with the occurrence of gastrointestinal adverse events induced by amino-BP, the serum levels of pepsinogen I and II were measured in amino-BP users. METHODS: When the patients complained of gastric distress symptoms during the first 6 months after amino-BP use resulting in discontinuation of the drug, endoscopical examinations were performed to assess whether gastric lesions were present. A total of 223 amino-BP users were enrolled in the study, of which 47 patients refused to take the drug due to gastric distress symptoms. The remaining 176 patients did not complain of any gastric distress. RESULTS: Among 47 patients, eight patients showed obvious gastric lesions such as gastric or duodenal ulcers and acute gastric mucosal lesions in the endoscopical examination. The remaining 39 patients did not show any gastric lesions. The possible confounding factors, such as a Helicobactor pylori infection or concurrent use of ulcerogenic agents, did cause not affect gastric distress in amino-BP users. The serum pepsinogen I level was significantly associated with severity of the gastric lesion 46.8 ± 27.7, 60.8 ± 32.4, and 103.4 ± 49.2 ng/ml for patients without any gastric distress, with gastric distress accompanied no gastric lesions, and with gastric distress accompanied gastric lesions, respectively. CONCLUSIONS: ROC analysis revealed that the cutoff value of pepsinogen I for expectation of gastric regions was 76.8 ng/ml. The results clearly indicate that measurement of pepsinogen I may be useful in predicting gastric distress induced by amino-BP in osteoporosis.
