BACKGROUND 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. METHODS Patients taking 100 mg aspirin for(More)
PURPOSE Interleukin-1beta (IL-1beta) polymorphisms are associated with peptic ulcer and atrophic gastritis. This study aimed to examine effects of corpus atrophy and the genotypes of genes related to peptic ulcer, including IL-1beta, on risk of aspirin ulcer. METHODS 232 patients taking 100 mg of aspirin for cardiovascular diseases, of whom 40 had peptic(More)
BACKGROUND We have previously shown that co-treatment of angiotensin type 1 receptor (AT1R) blocker (ARB) or angiotensin converting enzyme (ACE) inhibitor seem to reduce peptic ulcer among patients taking low dose aspirin. It is reported that a series of renin-angiotensin system (RAS) gene polymorphisms significantly influence the rate of the gene(More)
BACKGROUND  Although revascularization via coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) has been widely performed, there are limited data on which procedure is best in hemodialysis (HD) patients. METHODS AND RESULTS  This 10-year follow-up study consisted of 997 HD patients electively undergoing coronary(More)
BACKGROUND In the recent case-control study, we showed an inverse association between peptic ulcer and angiotensin type 1 receptor (AT1R) blockers (ARBs) or HMG-Co A reductase inhibitors (statins). The aim was to evaluate whether the genotypes of uptake and efflux transporters of ARBs and statins relate to the presence of peptic ulcer and/or ulcer bleeding(More)
The risk of peptic ulcer complications, particularly bleeding, is increased in association with the use of low-dose aspirin (LDA). Risk factors for upper gastrointestinal (GI) ulcer or bleeding among LDA users include a history of prior GI events, older age, chronic renal failure, combined antithrombotic therapy and nonsteroidal anti-inflammatory drugs(More)
There are a few studies of the association between genetic polymorphisms and the risks of acetylsalicylic acid (aspirin)-induced ulcer or its complications. Two single nucleotide polymorphisms (SNP) of cyclooxygenase-1 (COX-1), A-842G and C50T, exhibited increased sensitivity to aspirin and had lower prostaglandin synthesis capacity, lacking statistical(More)
BACKGROUND Aspirin-induced enteropathy is now increasingly being recognized although the pathogenesis of small intestinal damage induced by aspirin is not well understood and related risk factors have not been established. AIM To investigate pharmacogenomic profile of low dose aspirin (LDA)-induced small bowel bleeding. METHODS Genome-wide analysis of(More)
OBJECTIVE Antithrombotics is increasingly being used for cardiovascular prevention. In more recent studies, small bowel injury and enteropathy associated with low-dose aspirin are increasingly being recognized. Aim of this study was to evaluate small bowel injury using video capsule endoscopy (VCE) in obscure gastrointestinal bleeding (OGIB) patients taking(More)
A 36-year-old woman presented with a 10 mm diameter mass in the right breast. Since the mass persisted for 3 months after detection and mammary carcinoma was suspected based on ultrasonographic findings, the mass was resected. Histologically, the mass demonstrated proliferative margins and consisted of spindle cells with bland cytologic features and(More)
