The aims of this study were to demonstrate the trends in seropositivity and eradication therapy rate for Helicobacter pylori (H. pylori) over an 18-year period asymptomatic Korean population explore factors associated with H. its therapy. In total, 23,770 subjects (aged 17–97 years) from a health examination center participated cross-sectional January 2016 June 2017. Questionnaires that included questions about participants’ history collected, anti-H. IgG antibodies measured. Among eligible...
This study used image congruity theory to understand customer loyalty in name-brand coffee shops Korea. The authors developed and tested a structural model that links (self-congruity functional congruity) brand components (cognitive, affective, conative loyalty). elaboration likelihood was the information processing underlying model. results showed self-congruity significantly influences both cognitive affective central route of persuasion. Functional peripheral communication. suggests...
Atrophic gastritis is a precancerous condition, which can be diagnosed by several methods. However, there no consensus for the standard method. The aim of this study was to evaluate correlations among endoscopic, histologic, and serologic findings diagnosis atrophic gastritis.From March 2003 August 2013, total 2,558 subjects were enrolled. Endoscopic graded Kimura-Takemoto classification histological assessed updated Sydney system. Serological assessment based on serum pepsinogen test.The...
Functional dyspepsia (FD) is one of the most common gastrointestinal disorders, and FD imposes social economic burden worldwide. The aim this study to identify prevalence risk factors in health check-up population tertiary centers Korea.A nationwide multicenter prospective was performed at 9 healthcare Korea between September 2016 June 2017. A total 2525 subjects were investigated based on endoscopic findings questionnaires with Rome III criteria, Helicobacter pylori serology (IgG).A 1714...
Antimicrobial resistance of Helicobacter pylori (H pylori) affects the efficacy eradication therapy. The aim this study was to estimate prevalence primary and secondary H isolates antibiotics in Korea.The present performed from 2003 2018. Primary evaluated 591 patients without any history 149 whom cultured after failure eradication. A minimal inhibitory concentration test for amoxicillin, clarithromycin, metronidazole, tetracycline, levofloxacin, rifabutin using agar dilution method.An...
Tegoprazan is a novel potassium-competitive acid blocker used to treat acid-related disorders.To compare tegoprazan 25 mg with lansoprazole 15 as maintenance therapy in healed erosive oesophagitis (EE) METHODS: In this phase 3, double-blind, multi-centre study, patients endoscopically confirmed EE were randomised 1:1 receive or once daily for up 24 weeks. The primary efficacy endpoint was the endoscopic remission rate after secondary 12 Safety endpoints included adverse events, clinical...
Achalasia is classified into 3 types according to the Chicago classification. The aim of this study was investigate characteristics and treatment outcomes achalasia subtypes in Korean patients.Fifty-five patients diagnosed with based on conventional or high-resolution esophageal manometry were consecutively enrolled. Their clinical characteristics, manometric, endoscopic esophagographic findings responses analyzed among achalasia.Of 55 patients, 21 (38.2%) had type I, 28 (50.9%) II 6 (10.9%)...

Prokinetic agents and neuromodulators are among the treatment options for functional dyspepsia (FD), but their comparative efficacy is unclear. We aimed to compare of mosapride controlled-release (CR) nortriptyline in patients with FD after 4 weeks treatment.
Abstract Background The operative link on gastric atrophy (OLGA) and intestinal metaplasia (OLGIM) stages have been suggested for risk estimation of cancer (GC). However, usefulness OLGA/OLGIM systems in diffuse type GC was not investigated so far. aims this study were to evaluate the estimating according Lauren's classification investigate interaction among factors. Materials methods evaluated 1398 (765 control 633 patients) who prospectively enrolled Seoul National University Bundang...
Abstract Background The 13 C‐urea breath test ( C‐ UBT ) is a noninvasive method for diagnosing Helicobacter pylori H. infection. aims of this study were to evaluate the diagnostic validity cutoff value and identify influencing clinical factors responsible aberrant results. Methods UB iTkit; Otsuka Pharmaceutical, value: 2.5‰) results in range 2.0‰ 10.0‰ after eradication therapy compared with endoscopic biopsy antrum body. Factors considered affect adversely analyzed. Results Among patients...
The colonic response to stress is greater in female rats than male rats. aim of this study was evaluate the effect probiotics repeated water avoidance (rWAS)-induced microinflammation model Wistar a sex-specific manner. three groups (no-stress, WAS, and WAS with probiotics) were exposed r-WAS for 1 h daily 10 days, Lactobacillus farciminis administered by oral gavage days animals group. visceromotor (VMR) colorectal distension (CRD) assessed using barostat noninvasive manometry before after...
To identify whether first-degree relatives (FDRs) of gastric cancer (GC) patients have increased risk for atrophic gastritis (AG) and intestinal metaplasia (IM) in relation to other factors GC.The study cohort consisted 224 pairs age-sex matched controls FDRs. AG IM the mucosa were scored histologically using updated Sydney classification. Risk having was studied by comparing FDRs controls. Impacts age, H. pylori infection, smoking, dietary socioeconomic on presence studied.In multivariate...
Objective. The eradication rate of 10-day sequential therapy for Helicobacter pylori (H. pylori) infection was not satisfactory in Korea, probably due to antibiotic resistance. To compare the treatment efficacy 15-day and conventional 7-day proton pump inhibitor (PPI) triple H. infection. Methods. A total 332 patients with were randomly assigned receive either PPI therapy, or therapy. Eradication rate, drug compliance, adverse events compared among three regimens. Results. rates by...
Emerging evidence shows that the mechanism of irritable bowel syndrome (IBS) is associated with neurotrophic factors and tight junction proteins (TJPs). It known there are sex differences in pathophysiology IBS. The aim present study to determine expression levels factors, TJPs, cytokines according IBS subtype sex.From 59 (33 IBS-constipation, 21 IBS-diarrhea, 5 IBS-mixed) 36 control patients, colonic mucosa mRNA transient receptor potential vanilloid-1 (TRPV1), nerve growth factor (NGF),...
