This retrospective study aimed to investigate the effect of continuous LDA on the postoperative bleeding after gastric ESD in patients receiving dual antiplatelet therapy(DAPT).AIM To investigate the feasibility of gastric ESD with continuous LDA in patients with DAPT.METHODS A total of 597 patients with gastric neoplasms treated with ESD between January2010 and June 2017 were enrolled. The patients were categorized according to type of antiplatelet therapy(APT).RESULTS The postoperative bleeding rate was 6.9%(41/597) in all patients. Patients were divided into the following two groups: no APT(n = 443) and APT(n = 154). APT included single-LDA(n = 95) and DAPT(LDA plus clopidogrel, n = 59)subgroups. In the single-LDA and DAPT subgroups, 56 and 39 patients were received continuous LDA, respectively. The bleeding rate with continuous singleLDA(10.7%) was similar to that with discontinuous single-LDA(10.3%)(P >0.99). Although the bleeding rate with continuous LDA in patients receiving DAPT(23.1%) was higher than that with discontinuous LDA in patients receiving DAPT(5.0%), no significant difference was observed(P = 0.141).CONCLUSION The bleeding rate with continuous LDA in patients receiving DAPT was not statistically different from that with discontinuous LDA in patients receiving DAPT. Therefore, continuous LDA administration may be acceptable for ESD in patients receiving DAPT, although patients should be carefully monitored for possible bleeding.展开更多

They had kept taking the LDA or started treatmentduring the study period and kept taking LDA during the whole period of observation. Of these, 119 patients (87 males, 32 females) were diagnosed as having LDA-associated peptic ulcer. We examined the clinical factors associated with LDA-associated peptic ulcer in both sexes.RESULTS: A history of peptic ulcer was found to be the risk factor for LDA-associated peptic ulcer common to both sexes. In female patients, age greater than 70 years (prevalence ORs 8.441, 95% CI: 1.797-33.649, P = 0.0069) was found to be another significant risk fac-tor, and the time to diagnosis as having LDA-associat-ed peptic ulcer by endoscopy was significantly shorter than that in the male patients (P = 0.0050). CONCLUSION: We demonstrated gender differences about the clinical features and risk factors of LDA-asso-ciated peptic ulcer. Special attention should be paid to aged female patients taking LDA.展开更多

Helicobacter pylori(H. pylori) is major pathogen responsible for gastroduodenal ulcerformation. There have been conflicting results about the potential interaction between these two ulcerogenic factors and the geographic areas involved. In Western countries, the prevalence of gastroduodenal ulcers is consistently higher in H. pylori-positive low-dose aspirin(LDA) users than in H. pylori-negative ones, suggesting that H. pylori infection exacerbates LDA-induced gastroduodenal mucosal injury in these geographic areas. Meanwhile, previous studies from Japan have generally reported a similar prevalence of LDA-induced gastroduodenal mucosal injury regardless of the presence of H. pylori infection, indicating that the infection is not an overall exacerbating factor for drug-induced injury. H. pylori infection could have a synergistic or antagonistic interaction with LDA use in adverse gastroduodenal events depending on gastric acid secretion. It is wellrecognized that the net effect of H. pylori infection on gastric acid secretion shows considerable geographic variation at the population level. While gastric acid secretion levels were not decreased and were wellpreserved in most patients with H. pylori infection from Western countries, the majority of Japanese patients with H. pylori infection exhibited decreased gastric acid secretion. Such large geographic differences in the net effect of H. pylori infection on gastric acid secretion could be at least partly responsible for the geographically distinct interaction between LDA use and H. pylori infection on adverse gastroduodenal lesions.展开更多

We describe a case of esophageal mucosal lesion that was difficult to distinguish from malignancy in a patient with a history of ingesting LDA and prasugrel after implantation of a drug-eluting stent. Multiple auxiliary examinations were performed to make a definite diagnosis. The patient recovered completely after concomitant acid-suppressive therapy. Based on these findings, we strongly argue for the evaluation of the risk of gastrointestinal mucosal injury and hemorrhage if LDA therapy is required, and we stress the paramount importance of using drug combinations in individual patients.展开更多
