cardiovascular-agents and Helicobacter-Infections

We investigated the incidence of upper gastrointestinal lesions in the esophagus, stomach and duodenum in patients on low-dose aspirin (LDA) therapy.. The subjects were 101 consecutive outpatients who had been on LDA therapy (average age 67.2 +/- 8.3 years; male : female ratio 3.8:1). All subjects underwent endoscopy without ceasing their antiplatelet or anticoagulant therapy. We investigated the rates of endoscopic peptic ulcer, reflux esophagitis (RE) and malignant lesion.. RE was detected in eight subjects and esophageal ulcer in one subject. The severity of RE, according to the Los Angeles classification, was grade A in one subject, B in four, C in two and D in one. All nine subjects (8.9%) with RE and esophageal ulcer were negative for Helicobacter pylori infection. Gastric ulcer was detected in 12 subjects (six H. pylori positive, six negative) and duodenal ulcer in four (one H. pylori positive, three negative). The incidence of gastroduodenal ulcer was 15.8% (16/101). The incidence of esophageal and gastric cancers was high at 5.9% (6/101). Subjects were surveyed using the gastrointestinal symptom rating scale, with no differences in scores for acid reflux, abdominal pain or indigestion according to the presence or absence of RE, gastric ulceration or duodenal ulceration.. Upper gastrointestinal mucosal injuries and neoplasm were found in not only the stomach, but also the esophagus and duodenum in LDA taking subjects. These results emphasize the importance of endoscopic surveillance in patients on LDA therapy.

There are few studies on the association of the risks of upper gastrointestinal (GI) ulcer induced by aspirin combined with other medicines. We investigated the association between peptic ulcer and clinical parameters, including Helicobacter pylori infection and combinations of medicines.. Patients taking 100 mg aspirin for cardiovascular diseases who were planning to undergo endoscopy were enrolled. Serum H. pylori IgG antibody was measured.. A total of 305 patients were enrolled, and 38 patients (12.4%) had ulcer lesions. Sex, smoking, drinking, body mass index, endoscopic findings for gastric atrophy (open type), or presence of H. pylori were not significantly associated with ulcer lesions. Cotreatment with anticoagulants [ticlopidine, 34.2% vs. 21.3%; adjusted odds ratio (OR), 3.1; 95% confidence interval (CI), 1.4-7.1; ticlopidine plus warfarin, 13.2% vs. 3.7%; adjusted OR, 4.4; 95% CI, 1.3-15], proton pump inhibitor (PPI 5.3% vs. 34.8%; adjusted OR, 0.10; 95% CI, 0.02-0.43), and antihypertensive medicine were significantly associated with peptic ulcer. Among antihypertensive medicines, AT1 receptor blocker and angiotensin-converting enzyme (ACE) inhibitor tended to be associated with upper GI ulcer.. PPI was superior to H2-receptor antagonist for prevention of peptic ulcer, and cotreatment with AT1 receptor blocker or ACE inhibitor seemed to reduce peptic ulcer among patients taking low-dose aspirin.
