Association between GERD-related erosive esophagitis and obesity.
ABSTRACT To date, many studies have reported on the association of obesity with gastroesophageal reflux disease (GERD), although none of these have been systematic. In light of this, we conducted this study to examine the association of obesity and GERD.
A total of 3363 patients underwent gastroscopy at Hanyang University Health Promotion Center. Among these patients, we prospectively examined patients who were diagnosed with GERD-related erosive esophagitis on endoscopy.
Multivariate analysis showed that the significant risk factors were waist-to-hip ratio (WHR), hiatal hernia, body mass index (BMI), and smoking. As compared with patients who had a WHR less than 0.8, the multivariate odds ratio for erosive esophagitis were 4.055 for a WHR more than 1.0 and 2.316 for a WHR of 0.8 to 1.0. As compared with patients who had a BMI of 20 to 22.5, the multivariate odds ratio for erosive esophagitis was 3.308 (95% confidence interval, 1.792 to 6.107) for a BMI greater than 30.
Obesity, especially abdominal obesity, was the significant risk factor for erosive esophagitis.

ABSTRACT: Background/Aims Gastroesophageal reflux disease is one of the most common causes of chronic cough and is a potential risk factor for the exacerbation of chronic obstructive pulmonary disease (COPD). The aim of this study was to investigate the prevalence and risk factors for reflux esophagitis (RE) in COPD patients. Methods From our hospital database, between September 2006 and April 2010, we searched for subjects who were 40 years old or older and had undergone both postbronchodilator spirometry and esophagogastroduodenoscopy (EGD). COPD was defined as having a ratio of forced expiratory volume in 1 second to forced vital capacity < 0.7 in postbronchodilator spirometry and no abnormality causing airway obstruction, except emphysematous changes, on a chest X-ray. The diagnosis of RE was based on a mucosal break surrounding the distal esophageal sphincter through EGD. Results In total, 253 patients with COPD were enrolled. The prevalence of RE in COPD was 30% (76/253). Multiple logistic regression analyses revealed that age (odds ratio [OR], 0.950; 95% confidence interval [CI], 0.918 to 0.983; p = 0.003), smoking pack-years (OR, 1.015; 95% CI, 1.004 to 1.025; p = 0.006), and inhaled anticholinergics (OR, 0.516; 95% CI, 0.271 to 0.982; p = 0.044) were independently associated with RE in COPD patients. Conclusions The prevalence of RE in our COPD patients was higher than that reported previously in the Korean general population. In COPD, smoking increased the risk of RE, whereas inhaled anticholinergics may be associated with a reduced risk of RE.The Korean Journal of Internal Medicine 07/2014; 29(4):466-73.

ABSTRACT: Introduction: Risk factors and precipitants of gastro-oesophageal disease (GERD) differ widely in communities. We conducted an observational study to describe these risks, precipitants and clinical presentation of GERD patients at Kilimanjaro Christian Medical Centre (KCMC) in Tanzania. Methods: We consecutively recruited 92 GERD patients who were referred for endoscopy at KCMC from March to November 2008. By using structured questionnaire we enquired: risk factors, precipitants, symptoms of GERD and upper gastrointestinal endoscopic findings. Results: The mean (± SD) age of the study population was 47.32 (±17) years. Reported symptoms included water brash (37%), dyspepsia (6%), chronic cough (11%) and hemoptysis (5%). More than half (56%) of the patients surveyed identified food precipitants for their GERD symptoms. Triggers of GERD symptoms were boiled beans 19%, spicy food 11%, sour/fermented meals 10%, roasted tomato 9%, silver cyprinid fish (dagaa) 5%,beans with cooked green banana (matoke) 2% and fermented milk 1%. Most of the studied patients had normal body mass index (52%), and 25% admitted to be consuming alcohol though they didn’t associate it with their GERD symptoms. The most common endoscopy finding was ‘loose lower oesophageal sphincter (85%). Conclusion: Most GERD patients referred for endoscopy at KCMC were found to have water brash and ‘loose lower oesophageal sphincter’ as described by endoscopists to denote mechanical abnormality of the lower oesophageal sphincter.10/2014; 19(119).

ABSTRACT: Obesity and metabolic syndrome (MS) are strongly associated with erosive esophagitis (EE). The prevalence of MS and EE, and the distribution of adipose tissue have been known to differ markedly between men and women. Although the prevalence of EE in men with MS is known to be higher in visceral fat type MS (V-type MS) than in subcutaneous fat type MS (S-type MS), the association between EE and the types of MS in women with MS is unclear. This study was a cross-sectional study elucidating the association between EE and the types of MS in women with MS.Subjects were 454 women with MS who underwent a regular health check-up. A distinction was made between V-type MS and S-type MS and the prevalence of EE and the association between EE and other data were elucidated.Although there were some significant different factors in characteristics between V-type MS and S-type MS, there was no significant difference in the prevalence of EE between V-type MS and S-type MS. The presence of Helicobacter pylori (H. pylori) was significantly lower than in subjects with EE (13.7%) than in subjects without EE (41.9%). The frequency of hiatal hernia was significantly higher in subjects with EE (60.8%) than in subjects without EE (24.6%). Logistic regression analysis showed hiatal hernia (odds ratio: 4.673; 95% confidence interval: 2.448-8.920; P < 0.001), hemoglobin A1c (HbA1c) (2.325; 1.110-4.870; P < 0.05), and the presence of H. pylori (0.239; 0.101-0.567; P < 0.005) were significant predictors of the prevalence of EE.V-type MS may not be such an important factor for the prevalence of EE in women with MS as in men with MS. The absence of H. pylori, hiatal hernia, and HbA1c may be more important for the prevalence of EE than the types of MS in women with MS.Medicine 12/2014; 93(28):e276.
