Abstract
Gastroesophageal reflux impairs the mucosal barrier in the distal esophagus, allowing chronic exposure of the squamous epithelium to multitudinous stimulations and inducing chronic inflammation. Esophagitis is a response to inflammation of the esophageal squamous mucosa. Our study clarified that alcohol accumulation could aggravate the progress of esophagitis by inducing pyroptosis; however, Ac-YVAD-CMK, an inhibitor of caspase-1, could effectively suppress the expression of IL-1β and IL-18 both in vivo and in vitro, reducing the inflammatory response, which is promised to be an agent to inhibit the progression of esophagitis. Additionally, caspase-1-derived pyroptosis is involved in esophageal cancer.

Chung TH, Lee J, Kim MC. Impact of night-shift work on the prevalence of erosive esophagitis in shipyard male workers. Int Arch Occup Environ Health 2016; 89:961-6. [PMID: 27129469 PMCID: PMC4927591 DOI: 10.1007/s00420-016-1130-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2015] [Accepted: 04/11/2016] [Indexed: 02/07/2023]
Abstract
Purpose Whether night-shift work is a risk factor for gastroesophageal reflux disease is controversial. The aim of this study was to investigate the association between night-shift work and other factors, and erosive esophagitis. Methods A cross-sectional study with 6040 male shipyard workers was performed. Esophagogastroduodenoscopic examination and a survey about night-shift work status, lifestyle, medical history, educational status, and marital status were conducted in all workers. The odds ratios of erosive esophagitis according to night-shift work status were calculated by using the logistic regression model. Results The prevalence of erosive esophagitis increased in the night-shift workers [odds ratio, 95 % confidence interval: 1.41 (1.03–1.94)]. According to multiple logistic regression models, night-shift work, obesity, smoking, and alcohol consumption of ≥140 g/week were significant risk factors for erosive esophagitis. By contrast, Helicobacter pylori infection was negatively associated with erosive esophagitis. Conclusion Night-shift work is suggested to be a risk factor for erosive esophagitis. Avoidance of night-shift work and lifestyle modification should be considered for prevention and management of gastroesophageal reflux disease.

Abstract
Helicobacter pylori has been implicated in stimulation of immune system, development of autoimmune endocrinopathies as autoimmune thyroiditis (AT) and on other hand induction of immunosupresion activates gastric and extra-gastric diseases such as gastric ulcer or cancer. It causes persistent lifelong infection despite local and systemic immune response. Our results indicate that Helicobacter pylori might cause inhibition of the specific cellular immune response in Helicobacter pylori-infected patients with or without autoimmune diseases such as AT. We cannot also declare the carcinogenic effect in oropharynx. However the association of any infection agents and cancerogenesis exists. The adherence of Helicobacter pylori expression and enlargement of benign lymphatic tissue and the high incidence of the DNA of Helicobacter pylori in laryngopharyngeal and oropharyngeal cancer is reality. LTT appears to be a good tool for detection of immune memory cellular response in patients with Helicobacter pylori infection and AT. All these complications of Helicobacter pylori infection can be abrogated by successful eradication of Helicobacter pylori.

Abstract
AIM The aim of this study was to investigate the relationship between Helicobacter pylori infection and erosive reflux disease in children. METHODS A total of 206 children [mean age 8.4 +/- 4.9 (0.16-18) years] who underwent diagnostic upper endoscopy were tested for H. pylori infection between 2002 and 2005 and the relationship between H. pylori infection and gastro-oesophageal reflux disease was investigated retrospectively. Endoscopic and histopathological findings were examined retrospectively. When reflux-related oesophageal damage was identified as a result of the histological examination of endoscopic biopsy samples collected from distal oesophagus, the patients were diagnosed with gastro-oesophageal reflux disease and divided into two groups: those with macroscopic erosions or ulceration constituted the erosive oesophagitis group; those without constituted the non-erosive reflux disease group. RESULTS Prevalence of H. pylori infection was 31.3% in the patients with gastro-oesophageal reflux disease and 36.7% in the control group (p > 0.05). Prevalence of erosive oesophagitis was found to be 23.8% in the patients with H. pylori infection and 41.3% in those without (p > 0.05). CONCLUSION No negative significant association was found between the prevalence of H. pylori infection and erosive oesophagitis. Presence of H. pylori infection did not influence the severity of oesophagitis either.

Abstract
BACKGROUND Gastroesophageal reflux is a commonly encountered condition, but detailed data on reflux symptoms in Asian countries are lacking. GOALS To evaluate the prevalence and to document the clinical spectrum of endoscopic reflux esophagitis (RE). STUDY A total 25,536 subjects underwent an upper gastrointestinal endoscopic examination as part of a health check, and completed a gastroesophageal reflux questionnaire. Endoscopic findings classified according to the Los Angeles (LA) classification and the data from gastroesophageal reflux questionnaire were analyzed. RESULTS On the basis of endoscopic findings, 2019 subjects (7.91%) were found to have RE: 5.87% in LA-A; 1.84% in LA-B; 0.18% in LA-C; and 0.02% in LA-D. Heartburn, acid regurgitation, chest pain, hoarseness, globus sensation, cough, and epigastric soreness were found to be associated with RE (P<0.05). Heartburn, acid regurgitation, and epigastric soreness were more frequent in LA-B than in LA-A (P<0.05). Epigastric soreness was most bothersome in LA-A and LA-B, and acid regurgitation was most bothersome in LA-C and LA-D (P<0.01). Heartburn, hoarseness, and globus sensation were more frequent in men with RE, and acid regurgitation was most common in women. CONCLUSIONS The prevalence of RE was found to be 7.91% in Korea, and the profiles of reflux symptoms were found to depend on grade of RE and sex.

Abstract
Widespread epidemiological changes, rising prevalence and gradual shifts in patterns of disease manifestations: this is the changing face of gastroesophageal reflux disease (GERD) in Asia. Are we witnessing a disease in evolution or merely the result of increased and more accurate case reporting that comes with advancing diagnostic technology, better medical facilities and heightened awareness of the disease? Do the figures reported really reflect the actual scenario or is there more to it than meets the eye? In this article, we take you back in time to review relevant developments over the past decade or so. We will draw on findings from across Asia, take an in-depth look at prevailing trends and patterns and examine some of the most plausible explanations behind the dynamics of this epidemiological transition.

Abstract
BACKGROUND Prospective nationwide multicentre studies that have evaluated endoscopic findings and reflux symptoms using a well-designed questionnaire are very rare. AIM To compare the prevalence rates of and risk factors for erosive oesophagitis and non-erosive reflux disease (NERD) in the Korean population. METHODS A gastroscopic examination was performed on 25 536 subjects who visited 40 Healthcare Centers for a health check-up. A gastro-oesophageal reflux questionnaire and multivariate analysis were used to determine the risk factors for erosive oesophagitis and NERD. RESULTS 2019 (8%) and 996 subjects (4%) had erosive oesophagitis and non-erosive reflux disease, respectively; only 58% of subjects with erosive oesophagitis had reflux symptoms. Multivariate analysis showed that the risk factors for erosive oesophagitis and NERD differed, i.e. those of erosive oesophagitis were male, a Helicobacter pylori eradication history, alcohol, body mass index > or =25 and hiatal hernia. In contrast, the risk factors for NERD were female, age <40 and > or =60 vs. 40-59 years, body mass index <23 and a monthly income <$1000, glucose > or =126 mg/dL, smoking, a stooping posture at work and antibiotic usage. CONCLUSIONS The prevalence rates of erosive oesophagitis and NERD were 8% and 4%, respectively, in Korean health check-up subjects. The risk factors for erosive oesophagitis and NERD were found to differ, which indicates that their underlying pathogeneses are distinct.

Abstract
The clinical presentation of celiac disease in children changed in the last decades of the 20th century. To ascertain whether changes are still in progress, we analyzed symptoms at presentation and age at diagnosis in 307 children receiving diagnoses of celiac disease for the past 20 years. The prevalence of typical forms of celiac disease decreased in the past decade, particularly in the past 5 years (from 76% in 1987-1990 to 44%, P < 0.0001). Age at diagnosis (5.9 y, P = 0.01) and silent forms (10.6%, P = 0.003) have significantly increased in the past 5 years. Histological examination showed decreased subtotal and increased partial villous atrophy prevalence (P = 0.02).

Abstract
There is some evidence that Helicobacter pylori infection has a protective effect against gastroesophageal reflux disease (GORD) and its complications such as Barrett's oesophagus and oesophageal adenocarcinoma. In this paper, we propose that a neuroimmunological mechanism is responsible for the protective effect of H. pylori on GORD. H. pylori infection of the gastric mucosa induces a T helper1-like immune response and production of pro-inflammatory cytokines. These cytokines can inhibit local sympathetic tone, whereas they increase systemic sympathetic tone. Increased sympathetic tone can induce an anti-inflammatory milieu, which in turn can inhibit inflammation in the oesophagus and lower oesophageal sphincter (LOS). Furthermore, H. pylori infection may stimulate the cholinergic anti-inflammatory pathway. It has been suggested that reflux-induced oesophageal inflammation plays an important role in the pathogenesis of reflux oesophagitis. Reduction of oesophageal inflammation by increased systemic sympathetic tone and vagal activity may lead to a decrease in reflux-induced oesophageal injury and LOS dysfunction in GORD.
