BACKGROUND AND AIM We examined the incidence of symptomatic gastroesophageal reflux disease (GERD) in patients with type 2 diabetes mellitus (DM). METHODS Patients comprised those with DM or chronic hepatitis C (CHC) who visited Osaka Prefectural General Hospital in the same study period. Reflux symptoms were examined using a self-administered(More)
OBJECTIVE The aim of this study was to evaluate whether oral glucose tolerance test (OGTT) was useful in evaluating the prognosis of patients with liver cirrhosis. METHODS Fifty-six patients with liver cirrhosis were enrolled in a prospective cohort study. In all cases, glucose tolerance was diagnosed by a 75-g OGTT according to World Health Organization(More)
OBJECTIVE It is believed that oxidative stress, which is provoked in patients with diabetes, plays critical roles in the pathogenesis of myocardial infarction (MI). We simultaneously determined 5 relatively common genetic variants related to oxidative stress and evaluated the combined effect on MI. METHODS We enrolled 3819 Japanese type 2 diabetic(More)
I t is well known that postchallenge and postprandial hyperglycemia are related to the progression of diabetic macroangiopathy (1–6). However, there is little information regarding the association between diabetic microangiopathy and postprandial hyperglycemia in human subjects. In this study, we performed a follow-up study to elucidate the relationship(More)
We examined the association between diabetic retinopathy and monocyte chemoattractant protein (MCP)-1 A-2518G polymorphism in 3802 Japanese type 2 diabetic subjects. The prevalence of diabetic retinopathy was higher as the number of G alleles increased, suggesting that the G allele of this polymorphism is a susceptibility allele for diabetic retinopathy.
Diabetic microangiopathy is often observed in diabetic patients, but there is little evidence regarding the relationship between post-prandial glycemia or insulinemia and the incidence of diabetic microangiopathy. In this study, to elucidate the relationship between post-prandial glycemia (or insulinemia) and diabetic microangiopathy, we performed a(More)
BACKGROUND Although proton pump inhibitors (PPI) and H2-receptor antagonists (H2-RA) are routinely used in the treatment of reflux esophagitis (RE), no consensus has been reached yet as to whether the first-choice drug should be PPI or H2-RA. In this study, the effects of omeprazole (OMP) and famotidine (FAM) on RE have been examined in a randomized(More)
Vacuolating cytotoxin A (VacA) is one of the important virulence factors produced by H. pylori. VacA induces apoptotic cell death, which is potentiated by ammonia. VacA also causes cell death by mitochondrial damage, via signaling pathways that are not fully defined. Our aim was to determine whether endoplasmic reticulum (ER) stress is associated with(More)
Esophageal achalasia is considered as a risk factor of esophageal cancer. The etiologies of esophageal achalasia remain unknown. Peroral endoscopic myotomy (POEM) has recently been established as a minimally invasive method with high curability. The aims of the present study were to identify the microRNAs (miRs) specific to esophageal achalasia, to(More)
Common variable immune deficiency is the most frequently encountered immunodeficiency in adults, which is characterized by low levels of serum immunoglobulins. Common variable immune deficiency can present with inflammatory bowel disease-like colitis because of the dysregulated immune system; paradoxically activated T cell receptor pathways are thought to(More)
