Risk factors for erosive esophagitis: a cross-sectional study of a large number of Japanese males

The impact of obesity on gastroesophageal reflux disease remains controversial. We undertook this study, with a large sample size, to investigate risk factors for endoscopic erosive esophagitis by multivariate analysis, including visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) as covariates. Japanese males who visited our institute for a comprehensive medical survey between 2007 and 2010 were enrolled. All subjects voluntarily participated in a self-paid health check-up program including blood test screening, physical examinations, and esophagogastroduodenoscopy. VAT and SAT were measured by computed tomography at the navel level. Independent and significant predictors of erosive esophagitis were determined by multivariate analysis. Of 9840 eligible subjects, 1831 (18.6%) were diagnosed with erosive esophagitis. Body mass index and triglyceride were predictors of an increased prevalence of erosive esophagitis (odds ratios [ORs] = 1.063 and 1.001; 95% confidence intervals [CIs] = 1.020-1.108 and 1.001-1.002; p = 0.004 and <0.001, respectively). Heavy alcohol consumption, heavy smoking, and hiatal hernia were also associated with an increased prevalence of erosive esophagitis (ORs = 1.276, 1.399, and 2.758; 95% CIs = 1.085-1.501, 1.220-1.605, and 2.474-3.075; p < 0.001 for all). Helicobacter pylori infection significantly and independently decreased the prevalence of erosive esophagitis (OR = 0.346, 95% CI = 0.299-0.401, p < 0.001). Central obesity, as determined by VAT and waist girth, did not confer an increased risk of erosive esophagitis after adjusting for confounders. Lifestyle factors including heavy alcohol consumption, heavy smoking, metabolic disorders, and hiatal hernia increased the risk of erosive esophagitis, but central obesity did not.

The Relationship Between Visceral Adiposity and the Risk of Erosive Esophagitis in Severely Obese Chinese Patients

A higher prevalence of erosive esophagitis is found in obese than in nonobese patients; however, it remains unclear why some obese patients develop this disease, whereas others do not. Accordingly, we elucidated the risk factors associated with erosive esophagitis in severely obese Chinese patients. Between June 2007 and January 2009, a total of 260 Chinese patients with morbid obesity referred for bariatric surgery were enrolled in this cross-sectional study. All patients received preoperative endoscopy for evaluation of the presence and severity of erosive esophagitis. Demographic variables, anthropometric measurements, and metabolic factors were included in a logistic regression model to identify the factors predictive of erosive esophagitis. The prevalence of erosive esophagitis was 32.3%. Multiple logistic regression showed that increased waist circumference (odds ratio (OR) = 1.03, 95% confidence interval (CI) = 1.01-1.04), increased insulin resistance (OR = 1.57, 95% CI = 1.06-2.31), and presence of reflux symptoms (OR = 2.40, 95% CI = 1.22-4.74) were independent risk factors associated with erosive esophagitis. In conclusion, among Chinese patients with morbid obesity, increased waist circumference and insulin resistance were risk factors for erosive esophagitis, which highlights the critical role of visceral adiposity in the pathogenesis of erosive esophagitis.

Gastric surgery is not a risk factor for erosive esophagitis or Barrett's esophagus

Objective. The role of gastric acid reflux is difficult to separate from that of pancreatic-biliary reflux in the pathogenesis of erosive esophagitis (EE) and Barrett's esophagus (BE). Gastric surgery patients provide a good model for both significant pancreatic-biliary reflux and marked gastric acid inhibition. We assessed the risk of EE and BE after distal gastrectomy in a case-controlled study. Material and methods. One hundred and sixty patients (121 men, 39 women; median age 68 years; range 32–86 years) with distal gastrectomies (Billroth-I) and 160 sex- and age-matched controls with intact stomachs were enrolled. The presence of EE and BE were diagnosed based on the Los Angeles Classification and the Prague C & M Criteria, respectively. A conditional logistic regression model with adjustments for potential confounding factors was used to assess the associations. Results. According to the multivariate analyses, patients with distal gastrectomies tended to have inverse associations with the risks of EE and BE, and the inverse association with the risk of BE reached a significant level. Conclusions. Distal gastrectomy is not a risk factor for the development of EE and BE. This lack of a positive association between distal gastrectomy and EE and BE may suggest that pancreatic-biliary reflux with a limited amount of acid is not sufficient to damage the esophageal mucosa.

Risk Factors for the Occurrence of Erosive Esophageal in Patients with Dyspepsia

Background : The prevalence of erosive esophagitis tends to increase recently. It induces higher medical expense, loss of working time, and decreases quality of life. However the study on risk factors of erosive esophagitis scarcely reported in Indonesia. This study aimed to find the association between age, sex, smoking, alcohol drinking, body mass index, hiatal hernia, the use of non steroidal anti-inflammatory drugs (NSAID), and drugs that decrease lower esophageal sphincter (LES) tone with the occurrence of erosive esophagitis in dyspeptic patients. Method: A case-control study was conducted on patients with dyspepsia who underwent upper gastrointestinal endoscopy procedure and had been interviewed to determine risk factors for erosive esophagitis in July - September 2008. The association between risk factors and the occurrence of erosive esophagitis were analyzed using Chi-square, which subsequently revealed p < 0.25, this variable included in multivariate analysis. Result: There were 135 patients fulfilled criteria; 45 patients as cases and 90 patients as controls. The association was found between the occurrence of erosive esophagitis in dyspeptic patients and smoking more than 15 cigarette/day (OR 15.43; p = 0.00; CI 95% 4.77-49.88), the use of NSAID (OR 9.49; p = 0.00; CI 95% 2.77-32.53) and the consumption of drugs that decrease LES tone (OR 3.56; p = 0.02; CI 95% 1.26-10.02). Conclusion: Smoking more than 15 cigarettes/day, use of NSAID and drugs that decrease LES tone is a risk factors for the occurrence of erosive esophagitis. Keywords: erosive esophagitis, NSAID, smoking, drugs that decrease LES tone

Metabolic risk factors associated with erosive esophagitis

Our aim was to determine associations between metabolic risk factors and erosive esophagitis. In this retrospective case-control study, diagnosis of erosive esophagitis was based on the Los Angeles classification. Endoscopic findings in subjects with erosive esophagitis were reviewed by two experienced endoscopists and those with agreement of diagnosis were enrolled for study. Body mass index (BMI), abdominal girdle, blood pressure, and serum triglyceride, glucose, and beta-lipoprotein levels were compared between individuals with and without erosive esophagitis. Multivariate binary logistic regression analysis was used to identify independent metabolic risk factors associated with erosive esophagitis. Between October 2004 and April 2006, 518 of 4206 subjects who underwent endoscopic examination were diagnosed as having erosive esophagitis. After expert review, 427 (male : female = 365:62) individuals met the study criteria of having erosive esophagitis (10.5%). Compared with age- and gender-matched controls, patients with erosive esophagitis had significantly higher BMI, abdominal girdle, blood pressure, and triglyceride levels, and lower levels of high density lipoprotein (HDL) cholesterol (P < 0.05). More subjects with metabolic syndrome had erosive esophagitis than without metabolic syndrome (OR: 1.76, 95% CI: 1.27-2.44, P = 0.001). Multivariate logistic regression analysis revealed that central obesity (OR: 1.41, 95% CI: 05-1.89, P = 0.023) and hypertriglyceridemia (OR: 1.57, 95% CI: 1.19-2.13, P = 0.004) were significantly associated with erosive esophagitis. Obesity and hypertriglyceridemia, which are key components of metabolic syndrome, are moderate independent risk factors for erosive esophagitis.

Association Between Erosive Esophagitis and Visceral Fat Accumulation Quantified by Abdominal CT Scan

There were no objective data presented about the association between erosive esophagitis and abdominal fat. We conducted this study to examine the association of abdominal fat and gastroesophageal reflux disease-related erosive esophagitis. Between May 2004 and October 2005, a total of 100 erosive esophagitis patients diagnosed by upper endoscopy were evaluated in a prospective manner. All study patients and controls underwent abdominal computed tomography (CT) scan. Body fat distribution was assessed by CT with a 10-mm-thick slice at the level of the fourth lumbar vertebra. Erosive esophagitis patients presented with a significantly higher mean visceral fat (VF) area (104.68+/-39.47 vs. 75.90+/-49.10 cm2, P=0.014) than the control group. However, there was no association between erosive esophagitis and subcutaneous fat area (109.72+/-49.09 vs. 98.66+/-52.43 cm2, P=0.379) or total fat area (214.41+/-78.78 vs. 172.59+/-90.49 cm2, P=0.054). Multivariate logistic regression analysis demonstrated that high VF areas (P=0.0035), VF/subcutaneous fat area (P=0.005), hiatal hernia (P=0.001), high body mass index (P=0.047), high waist-to-hip ratio (P=0.042), and smoking (P=0.005) are independent risk factors of erosive esophagitis. These results suggest a role for visceral obesity, quantified by CT, as a risk factor for erosive esophagitis.

Association Between GERD-related Erosive Esophagitis and Obesity

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.

Metabolic syndrome is associated with erosive esophagitis.

To clarify whether insulin resistance and metabolic syndrome are risk factors for erosive esophagitis. A case-control study was performed using the database of the Kangbuk Samsung Hospital Medical Screening Center. A total of 1679 cases of erosive esophagitis and 3358 randomly selected controls were included. Metabolic syndrome was diagnosed in 21% of the cases and 12% of the controls (P < 0.001). Multiple logistic regressions confirmed the association between erosive esophagitis and metabolic syndrome (Odds ratio, 1.25; 95% CI, 1.04-1.49). Among the components of metabolic syndrome, increased waist circumference, elevated serum triglyceride levels and hypertension were significant risk factors for erosive esophagitis (all P < 0.01). Furthermore, increased insulin resistance (Odds ratio, 0.91; 95% CI, 0.85-0.98) and fatty liver, as diagnosed by ultrasonography (Odds ratio, 1.39; 95% CI, 1.20-1.60), were also related to erosive esophagitis even after adjustment for a series of confounding factors. Metabolic syndrome and increased insulin resistance are associated with an increased risk of developing erosive esophagitis.

Prevalence of Upper Gastrointestinal Tract Findings in Patients With Noncardiac Chest Pain Versus Those With Gastroesophageal Reflux Disease (GERD)-Related Symptoms: Results from a National Endoscopic Database

Available data on the prevalence of esophageal and upper gut findings in patients with noncardiac chest pain (NCCP) are scarce and limited to one center's experience. To determine the prevalence of esophageal and upper gut mucosal findings in patients undergoing upper endoscopy for NCCP only versus those with gastroesophageal reflux disease (GERD) symptoms only, using the national Clinical Outcomes Research Initiative (CORI) database. During the study period, the CORI database received endoscopic reports from a network of 76 community, university, and Veteran Administration Health Care System (VAHCS)/military practice sites. All adult patients who underwent an upper endoscopy for NCCP only or GERD-related symptoms only were identified. Demographic characteristics and prevalence of endoscopic findings were compared between the two groups. A total of 3,688 consecutive patients undergoing an upper endoscopy for NCCP and 32,981 for GERD were identified. Normal upper endoscopy was noted in 44.1% of NCCP patients versus 38.8% of those with GERD (P<0.0001). Of the NCCP group, 28.6% had a hiatal hernia (HH), 19.4% erosive esophagitis (EE), 4.4% Barrett's esophagus (BE), and 3.6% stricture/stenosis. However, HH, EE, and BE were significantly more common in the GERD group as compared with the NCCP group (44.8%, 27.8%, and 9.1%, respectively, P<0.0001). In univariate analysis of patients with NCCP, male gender was a risk factor for BE (OR 1.86, 95% CI 1.35-2.55, P=0.0001) and being nonwhite was protective (OR 0.43, 95% CI 0.22-0.86, P=0.02). In this group, male gender was also a risk factor for EE (OR 1.31, 95% CI 1.11-1.54, P=0.001) and age>or=65 yr was protective (OR 0.73, 95% CI 0.6-0.89, P=0.002). The NCCP group had a significantly higher prevalence of peptic ulcer in the upper gastrointestinal tract as compared with the GERD group (2.0% vs 1.5%, P=0.01). In this endoscopic prevalence study, most of the endoscopic findings in NCCP were GERD related, but less common as compared with GERD patients.

Risk factors for gastroesophageal reflux disease, reflux esophagitis and non-erosive reflux disease among Chinese patients undergoing upper gastrointestinal endoscopic examination

To analyze the spectrum and risk factors of gastroesophageal reflux disease (GERD) based on presenting symptoms and endoscopic findings. A cross-sectional survey in a cluster random sample was conducted from November 2004 to June 2005 using a validated Chinese version Reflux Disease Questionnaire (RDQ) and other items recording the demographic characteristics and potential risk factors for GERD. Subjects were defined as having GERD symptoms according to the RDQ score (> 12). All subjects were endoscopied and the definition and severity of erosive esophagitis were evaluated by Los Angeles classification. The statistical analysis was performed with SPSS13.0 programs. Of 2,231 recruited participants, 701 (31.40%) patients were diagnosed as having GERD while 464 (20.80%) patients had objective findings of reflux esophagitis (RE). Of those 464 patients, only 291 (13.00%) were reported as subjects with GERD symptoms. A total of 528 (23.70%) patients were found to have GERD symptoms, including 19.50% patients with grade A or B reflux esophagitis, 0.90% with grade C and 0.40% with grade D. On multivariate analysis, old age, male, moderate working burden, divorced/widowed and strong tea drinking remained as significant independent risk factors for erosive esophagitis. Meanwhile, routine usage of greasy food and constipation were considered as significant independent risk factors for non-erosive reflux disease (NERD). GERD is one of the common GI diseases with a high occurrence rate in China and its main associated factors include sex, anthropometrical variables and sociopsychological characteristics.

Abdominal obesity is an independent risk factor for erosive esophagitis in a Korean population

The relationship between obesity and gastroesophageal reflux disease (GERD) is controversial. The aim of the present study was to investigate the potential roles of body mass index (BMI) and waist circumference on GERD in a Korean population. A total of 2457 subjects who visited the Kangbuk Samsung Hospital medical screening center for esophagogastroduodenoscopy from September 2004 to April 2005 were enrolled. All participants were given a questionnaire to determine reflux symptoms. Abdominal obesity was defined as a waist circumference > or =80 cm in women and > or =90 cm in men. The proportion of subjects in each BMI group was 68.9%, 28.7% and 2.4% for BMI <25, 25-30 and >30, respectively. The prevalence of abdominal obesity was 24.2%. The prevalence of reflux symptoms was 8.2%. Neither BMI nor abdominal obesity was significantly associated with reflux symptoms after adjustment. The prevalence of erosive esophagitis was 6.6%. There was a clear dose-response relationship between prevalence of erosive esophagitis and BMI (5.6%, 8.1% and 15.5% for BMI <25, 25-30 and >30, respectively, P = 0.002). Abdominal obesity was also associated with erosive esophagitis (odds ratio, 2.3; 95% confidence interval, 1.6-3.1). However, only the association between abdominal obesity and erosive esophagitis remained strong after adjustments. Abdominal obesity rather than BMI is an independent risk factor for erosive esophagitis in the Korean population.

Comparative analysis between psychological and endoscopic profiles in patients with gastroesophageal reflux disease: A prospective study based on screening endoscopy

Associations between psychological and endoscopic profiles are not clearly validated among the heterogeneous patients with gastroesophageal reflux disease (GERD). The purpose of the present paper was therefore to identify any associations by means of cross-sectional study. Consecutive participants in a health screening program were enrolled. Definition and severity of erosive esophagitis were assessed with Los Angeles classification. Frequency and severity of psychological symptoms were measured with a 30-item Brief Symptom Rating Scale (BSRS) and personality traits with a short form of the Maudsley Personality Inventory (MPI). Statistic analyses were performed based on the presence of GERD symptoms or endoscopic esophagitis. A total of 4600 participants were recruited. There were 1331 subjects (29%) with manifestations suggesting GERD, including non-erosive reflux disease (NERD) in 488 (10.6%), symptomatic erosive esophagitis (SEE) in 164 (3.6%), and asymptomatic erosive esophagitis (AEE) in 679 (14.8%). The BSRS parameters were significantly higher in symptomatic subjects (i.e. NERD and SEE subjects; P < 0.001); neuroticism scores were also higher (P < 0.001), but extroversion scores (P < 0.001) were lower than those of asymptomatic subjects. Following logistic regression analysis, independent risk factors for GERD symptoms were female gender (odds ratio [OR]: 1.596; 95% confidence interval [CI]: 1.303-1.955) and higher neuroticism scores (OR: 1.046; 95%CI: 1.032-1.06). For erosive esophagitis, independent risk factors were male gender (OR: 2.943; 95%CI: 2.359-3.671) and higher body mass index scores (OR: 1.098; 95%CI: 1.069-1.127). Psychological characteristics predict likelihood of GERD symptoms but not structural state of esophagus. Male gender and obesity are risk factors for erosive esophagitis; whereas female gender and neuroticism are more likely to be associated with GERD symptoms.

Risk factors for erosive esophagitis: a multivariate analysis based on the ProGERD study initiative.

Gastroesophageal reflux disease can be divided into three categories: nonerosive GERD (NERD), erosive GERD (ERD), and Barrett's esophagus. A shift among these categories rarely occurs. The aim of the present study was to elucidate potential patient-associated risk factors associated with ERD. A total of 6,215 patients with troublesome heartburn were recruited to a large, prospective, multicenter open cohort study comprising an initial treatment phase and a 5-yr follow-up phase. Each center planned to recruit an equal number of patients with NERD and ERD. All patients underwent an interview based on standardized questionnaires, a physical examination, and endoscopy with biopsies. Data were analyzed by multiple logistic regression analysis. Risk factor analysis was performed on 5,289 patients (NERD: n = 2,834; ERD: n = 2,455), which was the intent-to-treat population excluding patients with suspected/proven complicated reflux disease. Stepwise regression analysis identified the following independent predictors of ERD: male gender, overweight, regular use of alcohol, a history of GERD >1 yr, and smoker or ex-smoker. A higher level of education and a positive Helicobacter pylori (H. pylori) status were associated with a lower risk of ERD. Some patient-associated factors increase the risk of erosive esophagitis as opposed to nonerosive reflux disease. However, no single factor or combination of factors is capable of predicting mucosal damage with clinically sufficient certainty. Thus, endoscopy is still required in all GERD patients if valid information on the state of the esophageal mucosa is needed.
