1.Natural History and Overlap of Functional Gastrointestinal Disorders.
The Korean Journal of Gastroenterology 2012;60(6):345-348
Functional gastrointestinal (GI) disorders are common in the general population. Based on the Rome III classification, these disorders are mutually exclusive disorders keeping the homogeneity of each functional GI disorder in research area. In contrast, many population and clinical studies have reported a considerably high rate of overlap between functional GI disorders. The overlap of functional GI disorders over other intestinal diseases might simply occur by chance due to a highly prevalent disorder. Moreover, functional GI disorders is considered a chronic stable disorder that may wax and wane for several years. However, a recent study about the natural history of functional GI disorders showed substantial transition among functional GI disorders over time. The natural history of functional GI disorders with overlapping other functional GI disorders are still in infancy and better understanding of these will be important in determining the efficacy of future therapeutic interventions.

BACKGROUND/AIMS: Eosinophilic esophagitis (EE) is a chronic inflammatory disorder characterized by abnormal dense eosinophilic infiltration of esophageal mucosa and results in dysphasia and food impaction. EE is being increasingly recognized in adults. The prevalence is largely unknown. This study was performed to evaluate the detection rate of EE diagnosed based on pathologic criteria and to define the clinical characteristics of EE in Korea. METHODS: We reviewed biopsy specimen of the 1,609 patients who underwent esophageal biopsy from January 2006 till August 2008. The presence of more than 20 eosinophils per high power field in biopsy specimens was considered cases of EE. Clinical information and endoscopic findings were obtained. RESULTS: 7 (0.4%) patients were diagnosed as EE based on pathologic criteria retrospectively. Clinical symptoms were epigastric pain (43%), regurgitation (29%), dyspepsia (14%), and no symptom (14%). Endoscopic findings were whitish exudates or granules (57%), esophageal polyp (29%), and hyperemic change (14%). Two patients received treatment. One patient with bronchial asthma improved after treatment with inhaled corticosteroid, and one patient improved after 8 week proton pump inhibitor therapy. CONCLUSIONS: Eosinophilic esophagitis was found in 0.4% of the total esophageal biopsied cases. Our results suggest that Korean patients with eosinophilic esophagitis showed symptoms mimicking gastroesophageal reflux disease and atypical endoscopic findings. Therefore, regardless of the gross appearance of the mucosa, meticulous diagnostic approaches are needed for patients with swallowing difficulty and lack of response to proton pump inhibitor.

BACKGROUND/AIMS: We aimed to estimate the proportion of significant endoscopic findings and their association with dyspeptic symptoms and to evaluate the predictors for significant endoscopic findings. METHODS: Total of 3,872 subjects (58.3% men, mean age 43.6+/-9.3 years) who had undergone endoscopy were enrolled at the health promotion center. Each subject completed validated questionnaires, including data on gastrointestinal symptoms, socio-demographic history and medical history. Significant endoscopic findings were included peptic ulcer disease, reflux esophagitis, gastric cancer, Barrett's esophagus and gastro-duodenal erosions. Multiple logistic regression models were used to assess the predictors for significant endoscopic findings. RESULTS: The proportion of significant endoscopic findings was 39.1%. There was no significant difference of endoscopic findings between the dyspepsia and asymptomatic group (41.0% vs. 37.4%, p>0.05). There was no difference of the incidence of reflux esophagitis or peptic ulcer between subjects with and without dyspepsia. Peptic ulcer was more frequently present in subjects with reflux symptoms than asymptomatic subjects (12.3% vs. 9.0%, p=0.03). Male gender (odds ratio [OR], 3.91; 95% confidence interval [CI], 3.18-4.81) increased the risk for having endoscopic abnormality and having symptoms of functional dyspepsia according to Rome III criteria (OR, 0.75; 95% CI, 0.57-0.97) significantly decreased this risk. CONCLUSIONS: About 40% of subjects with dyspepsia had abnormal endoscopic findings, and the dyspepsia symptoms may not predict the significant endoscopic findings. Diagnostic criteria of functional dyspepsia by Rome III may be useful to predict not having significant upper endoscopic findings.
