Background
/Aims: Helicobacter pylori (H. pylori) seroconversion may occur during screening for gastric cancer. Our study aimed to assess the number of seroconverted subjects with H. pylori and their results in follow-up tests.
Methods
Data were consecutively collected on subjects who were H. pylori-seronegative and presented for gastric cancer screening. Subjects who were followed up using the same serology test and pepsinogen (PG) assays on the day of endoscopy were included in the study.
Results
During the follow-up of 57.7±21.4 months, 61 (15.0%) of 407 seronegative subjects showed seroconversion. H. pylori infection was detected in six (9.8%) of 61 seroconverted subjects. A diffuse red fundal appearance, with a significant increase in the Kyoto classification scores for gastritis, was observed in the infected subjects (p<0.001). Compared to the false-seropositive subjects, infected subjects showed higher serology titers (p<0.001) and PG II levels (p<0.001) and lower PG I/II ratios (p=0.002), in the follow-up tests.
Conclusions
Seroconversion occurred in 3.3% of seronegative subjects per year; however, only 9.8% had H. pylori infection. The majority (90.2%) of the seroconverted subjects showed false seropositivity without significant changes in the follow-up test results. The diffuse red fundal appearance could be an indicator of H. pylori infection.

Risk Factors for the Presence of Symptoms in Peptic Ulcer Disease
Sang Pyo Lee, In-Kyung Sung, Jeong Hwan Kim, Sun-Young Lee, Hyung Seok Park, Chan Sup Shim

Background
/Aims: Peptic ulcer disease (PUD) is a common condition, but is difficult to detect in asymptomatic individuals. We aimed to investigate the prevalence of symptomatic and asymptomatic PUD during screening endoscopy and to identify risk factors for the presence of symptoms in patients with PUD.
Methods
We investigated subjects who underwent a health inspection, including endoscopy of the upper gastrointestinal (GI) tract and a serum anti-Helicobacter pylori IgG assay, and who completed a self-report questionnaire about their symptoms.
Results
Of the 12,852 subjects included in the study, 124 (1.0%) had symptomatic PUD and 309 (2.4%) had asymptomatic PUD. Old age, current smoking, and H. pylori infection were independent risk factors for symptomatic and asymptomatic PUD. Use of non-steroidal anti-inflammatory drugs (NSAIDs) was an independent risk factor only for symptomatic PUD (p=0.040). Compared to subjects with asymptomatic PUD, subjects with symptomatic PUD were more likely to have active-stage ulcers (p=0.002) and to drink more heavily (p=0.005).
Conclusions
Use of NSAIDs is a risk factor for symptomatic PUD, but not for asymptomatic PUD. Excessive alcohol consumption and active-stage ulcers in patients with PUD are related to the presence of gastroduodenal symptoms.

Background/Aims

Improvements in the endoscopic evaluation and management of gastric cancer have made it possible to determine the depth of invasion during endoscopic examination. The aim of this study was to elucidate the differences between early gastric cancer (EGC) that resembles advanced gastric cancer (AGC) and AGC that resembles EGC.

Methods

We retrieved cases of EGC-like AGC and AGC-like EGC from consecutive gastric cancers that had been completely resected. The endoscopic diagnoses and clinicopathological findings were analyzed.

Results

AGC-like EGCs were located mainly in the distal part of the stomach, whereas EGC-like AGCs were located mainly in the proximal part of the stomach (p<0.001). Sixty percent of AGC-like EGCs were moderately differentiated adenocarcinomas, while 64% of EGC-like AGCs were poorly differentiated adenocarcinomas (p=0.015). According to Lauren's classification, 68% of AGC-like EGCs were intestinal type, whereas 71% of EGC-like AGCs were diffuse type (p=0.020).

Conclusions

AGC-like EGCs predominate in the distal part of the stomach, while EGC-like AGCs predominate in the proximal part. When evaluating the depth of a gastric cancer, care should be taken not to underestimate measurements in proximal gastric cancers since they tend to be poorly-differentiated adenocarcinomas, in Lauren's diffuse type, and invade deeper than their endoscopic appearance might suggest.
