Risk Factors For Reflux Esophagitis Research Articles

Short-term outcomes and quality of life of esophagogastrostomy versus the double-tract reconstruction after laparoscopic proximal gastrectomy

BackgroundThere is no optimal reconstruction technique after proximal gastrectomy. The esophagogastrostomy (EG) is a rather simple procedure technically, but the incidences of reflux esophagitis and anastomotic stricture are higher. While the double-tract reconstruction (DTR) can lessen postoperative reflux esophagitis, it is technically complex with a long operation time. The purpose of this study was to evaluate the quality of life (QoL) and short-term outcomes of the two reconstruction techniques.MethodsWe retrospectively collected consecutive patients with upper-third gastric adenocarcinoma and adenocarcinoma of the esophagogastric junction (AEG) at our center between 2019 June and 2023 May. Patients who underwent laparoscopic proximal gastrectomy (LPG) with EG or DTR were included in this study. A comparison was made between the clinical and pathological characteristics of patients and their surgical parameters, postoperative complications, and its 1-year QoL in two groups. The QoL of the two groups was assessed by Visick grading, the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and EORTC QLQ-STO22 scales at 1 year after operation. The nutritional status of the two groups was evaluated by BMI, hemoglobin and serum albumin.ResultsAII the qualified patients were divided EG group (n = 63) and DTR group (n = 93). Compared to the DTR group, the blood loss volume of EG group was more (p = 0.001). There were no significant differences in operation duration, number of lymph nodes dissected, and postoperative length of stay between the two groups(p > 0.05). No statistical differences were observed in terms of the incidence of early complications and Clavien-Dindo classification as well(p > 0.05). After one year, the Visick grade of the DTR group was better than EG group (p = 0.040). The multivariable logistic regression analysis showed the only independent risk factor for reflux esophagitis was the reconstruction method. According to the EORTC QLQ-C30 questionnaire, patients in the DTR group had a better global health status(p = 0.001) and complained less about nausea and vomiting(p = 0.033), and appetite loss (p = 0.022). Patients in the DTR group complained less about reflux (p = 0.030) based on the EORTC QLQ-STO22 questionnaire. The multiple linear regression analysis revealed that the reconstruction method, reflux esophagitis and age had a linear relationship with the global health status score. Regarding nutritional status, BMI of the two groups both decreased 1 year after operation, and BMI decline value of the DTR group was lower than EG group (p = 0.001). There is no statistically significant difference between the two groups as for postoperative change in hemoglobin and serum albumin.ConclusionOur findings suggest that it is possible for skilled surgeons to achieve minimal blood loss volume without significantly increasing operation duration when performing DRT, which does not raise risk. In terms of anti-reflux, postoperative QoL and BMI maintenance, 1-year postoperative follow-up outcomes reveal the DTR is superior to EG, which deserve further research and promotion.

Unveiling the hidden pathologies: preoperative endoscopic findings in patients with obesity undergoing bariatric surgery

BackgroundObesity is closely associated with upper gastrointestinal disorders. The recommendations for routine preoperative esophagogastroduodenoscopy (EGD) before bariatric surgery remains a topic of debate. This study aimed to describe the pathological endoscopic findings in individuals qualified for bariatric surgery.MethodsRetrospective analysis was conducted on preoperative gastroscopy reports of patients who underwent bariatric surgery at our hospital between October 2022 and October 2023.ResultsA total of 405 patients were included in the study. The two most prevalent endoscopic findings during EGD in this patient cohort were chronic superficial gastritis (326/405, 80.5%) and reflux esophagitis (82/405, 20.2%). Some patients exhibited two or more abnormalities. Patients with reflux esophagitis were older, had a higher proportion of men, higher BMI, higher rates of smoking and drinking compared to those without it (P = 0.033, P < 0.001, P = 0.003, P = 0.001, and P = 0.003, respectively). Morbid obesity (P = 0.037), smoking habits (P = 0.012), and H. pylori infection (P = 0.023) were significant risk factors for reflux esophagitis in male patients, while age (P = 0.007) was the sole risk factor in female patients. No statistically significant differences were observed in surgical procedures between LA-A and B groups (P = 0.382), but statistically significant differences were noted between the nondiabetic and diabetic groups (P < 0.001).ConclusionsPreoperative EGD can unveil a broad spectrum of pathologies in patients with obesity, suggesting the need for routine examination before bariatric surgery. The findings of this study can guide bariatric surgeons in developing tailored treatments and procedures, thus significantly enhancing prognosis. Gastroscopy should be performed routinely in Chinese patients planning to undergo bariatric surgery.

Visceral Adipose Tissue Reduction Measured by Deep Neural Network Architecture Improved Reflux Esophagitis Endoscopic Grade.

Visceral obesity is a risk factor for reflux esophagitis (RE). We investigated the risk of RE according to visceral adipose tissue (VAT) measured by deep neural network architecture using computed tomography (CT) and evaluated the longitudinal association between abdominal adipose tissue changes and the disease course of RE. Individuals receiving health checkups who underwent esophagogastroduodenoscopy (EGD) and abdominal CT at Seoul National University Healthcare System Gangnam Center between 2015 and 2016 were included. Visceral and subcutaneous adipose tissue areas and volumes were measured using a deep neural network architecture and CT. The association between the abdominal adipose tissue area and volume and the risk of RE was evaluated. Participants who underwent follow-up EGD and abdominal CT were selected; the effects of changes in abdominal adipose tissue area and volume on RE endoscopic grade were investigated using Cox proportional hazards regression. We enrolled 6,570 patients who underwent EGD and abdominal CT on the same day. RE was associated with male sex, hypertension, diabetes, excessive alcohol intake, current smoking status, and levels of physical activity. The VAT area and volume increased the risk of RE dose-dependently. A decreasing VAT volume was significantly associated with improvement in RE endoscopic grade (hazard ratio: 3.22, 95% confidence interval: 1.82-5.71). Changes in subcutaneous adipose tissue volume and the disease course of RE were not significantly correlated. Visceral obesity is strongly associated with RE. VAT volume reduction was prospectively associated with improvement in RE endoscopic grade dose-dependently. Visceral obesity is a potential target for RE treatment.

Incidence and risk factors of reflux esophagitis after peroral endoscopic myotomy.

Peroral endoscopic myotomy (POEM) is an effective and safe treatment for achalasia, but often leads to posttreatment gastroesophageal reflux disease. The aim of this study was to examine the incidence and severity of reflux esophagitis after POEM and to identify associated predictive factors. Patients who underwent POEM between August 2011 and December 2022 were included. Multivariate logistic regression was used to assess predictive factors for reflux esophagitis after POEM. In total, 252 patients were included; of which, 46% were female and age ranged between 18 and 87 years. Reflux esophagitis within 1 year after POEM was observed in 131 patients (52%), which was severe in 29 patients (LA grade C/D, 12%). Length of full-thickness myotomy (cm; OR 1.11, 95% CI 1.02-1.21), Eckardt scores before POEM (OR 0.84, 95% CI 0.74-0.96), previous pneumatic dilation (OR 0.51, 95% CI 0.29-0.91), and previous laparoscopic Heller myotomy (LHM; OR 0.44, 95% CI 0.23-0.86) were associated with reflux esophagitis after POEM. Alcohol use (none vs > 7 units per week; OR 3.51, 95% CI 1.35-9.11) and overweight (BMI ≥25 kg/m2; OR 2.67, 95% CI 1.17-6.09) were positive predictive factors and previous LHM (OR 0.13, 95% CI 0.02-0.95) was a negative predictive factor for severe reflux esophagitis after POEM (LA grade C/D). About half of the patients develop reflux esophagitis after POEM and 12% is graded as severe. Recognizing predictive factors of reflux esophagitis after POEM treatment leads to better patient selection before POEM and provides an opportunity to take preventive measures or start preemptive treatment.

Immunoglobulin G-mediated food intolerance and metabolic syndrome influence the occurrence of reflux esophagitis in Helicobacter pylori-infected patients.

Reflux esophagitis has an increasing prevalence and complex and diverse symptoms. Identifying its risk factors is crucial to understanding the etiology, prevention, and management of the disease. The occurrence of reflux esophagitis may be associated with food reactions, Helicobacter pylori (H. pylori) infection, and metabolic syndromes. To investigate the risk factors for reflux esophagitis and analyze the effects of immunoglobulin (Ig) G-mediated food intolerance, H. pylori infection, and metabolic syndrome on reflux esophagitis. Outpatients attending the Second Medical Center of the PLA General Hospital between 2017 and 2021 were retrospectively enrolled. The patients' basic information, test results, gastroscopy results, H. pylori test results, and IgG-mediated food intolerance results were collected. Multivariate logistic regression analysis was used to analyze risk factors for reflux esophagitis. Statistical mediation analysis was used to evaluate the effects of IgG-mediated food intolerance and metabolic syndrome on H. pylori infection affecting reflux esophagitis. A total of 7954 outpatients were included; the prevalence of reflux esophagitis, IgG-mediated food intolerance, H. pylori infection, and metabolic syndrome were 20.84%, 61.77%, 35.91%, and 60.15%, respectively. Multivariate analysis showed that the independent risk factors for reflux esophagitis included IgG-mediated food intolerance (OR = 1.688, 95%CI: 1.497-1.903, P < 0.00001) and metabolic syndrome (OR = 1.165, 95%CI: 1.030-1.317, P = 0.01484), and the independent protective factor for reflux esophagitis was H. pylori infection (OR = 0.400, 95%CI: 0.351-0.456, P < 0.00001). IgG-mediated food intolerance had a partially positive mediating effect on H. pylori infection as it was associated with reduced occurrence of reflux esophagitis (P = 0.0200). Metabolic syndrome had a partially negative mediating effect on H. pylori infection and reduced the occurrence of reflux esophagitis (P = 0.0220). Patients with IgG-mediated food intolerance and metabolic syndrome were at higher risk of developing reflux esophagitis, while patients with H. pylori infection were at lower risk. IgG-mediated food intolerance reduced the risk of reflux esophagitis pathogenesis in patients with H. pylori infection; however, metabolic syndrome increased the risk of patients with H. pylori infection developing reflux esophagitis.

The Association between Smoking Exposure and Reflux Esophagitis: A Cross-sectional Study among Men Conducted as a Part of Health Screening.

Objective Gastroesophageal reflux disease (GERD), including reflux esophagitis (RE), is recognized as a common gastrointestinal disease, and its prevalence is reported to be increasing. While current cigarette smoking has been established as a risk factor for RE in several cross-sectional studies, most of these studies did not include details concerning the smoking status in their analyses. Smoking-related conditions, such as chronic lung disease and cough, are reportedly also related to GERD. Methods To investigate the association between RE and detailed smoking habits, we performed a cross-sectional analysis of healthy men enrolled in a comprehensive health checkup program conducted in 2015 that included esophago-gastro-duodenoscopy. Smoking status was assessed using a self-reported questionnaire. Other smoking-related parameters, including the lung function, cough symptoms and presence of chronic lung disease, were also assessed. Unconditional logistic regression was applied to calculate the odds ratio (OR) with 95% confidence intervals (CIs) after adjusting for confounding factors. Results The study included 151 subjects with RE (RE group) and 814 without RE (control group). Compared with never-smokers, former smokers (OR, 1.5; 95% CI, 0.9-2.9) and current smokers (OR, 2.4; 95% CI, 1.5-3.9) showed an increased risk of RE. An increased risk of RE was also observed among subjects with current smoking for 10-20 PYs and more than 20 PYs (OR, 2.8; 95% CI, 1.4-5.8, OR, 3.1; 95% CI, 1.6-5.7 respectively). An elevated risk was observed in former smokers who reported more than 20 PYs (OR, 2.5; 95% CI, 1.3-4.8). When former smokers were stratified according to time since smoking cessation, a significant RE risk was observed in participants who had stopped smoking less than 10 years earlier compared with never smokers (OR, 1.9; 95% CI, 1.1-3.3). No significant associations were observed between chronic cough, FEV1.0%, and RE. Conclusion Cumulative lifetime exposure to smoking plays an important role in the risk of RE.

Increased risk of reflux esophagitis in non-obese individuals with nonalcoholic fatty liver disease: a cross-sectional study

Background Non-alcoholic fatty liver disease (NAFLD) and gastroesophageal reflux disease (GERD) are both associated with obesity. However, the relationship of NAFLD with reflux esophagitis (RE) is still unclear in non-obese individuals. Methods Individuals with a body mass index (BMI) of 28 kg/m2 or higher, as well as waist circumference (WC) no less than 90 cm for men and no less than 85 cm for women were excluded. After controlling for other factors, 1905 eligible adult subjects were included. The components related to metabolic syndrome and the prevalence of NAFLD in the RE group as well as the non-RE group were analyzed. Risk factors for RE were determined using logistic regression. Results In non-obese individuals, the prevalence of RE and NAFLD increased with increasing WC and BMI (p < 0.001). Based on the results of logistic regression analysis, NAFLD was found to increase the risk of RE with statistical significance. Even after adjusting for metabolic syndrome and other related factors, NAFLD remained an independent influencing factor for the risk of RE (OR = 2.029; 95% CI 1.459–2.821, p < 0.001). Conclusions The prevalence of NAFLD was significantly higher in patients with RE compared to those without RE. These results indicate that NAFLD has a potential as an independent risk factor for RE, even in non-obese individuals.

Lean/normal-weight metabolic dysfunction-associated fatty liver disease is a risk factor for reflux esophagitis.

Reflux esophagitis is associated with metabolic dysfunction. Recently, fatty liver has been redefined as metabolic dysfunction-associated fatty liver disease (MAFLD). We investigated the impact of MAFLD and its subtypes on the incidence of reflux esophagitis. This multicenter, observational cohort study enrolled 9100 consecutive health-check examinees who underwent esophagogastroduodenoscopy and ultrasonography. All patients were classified into the MAFLD or non-MAFLD group. Based on the Asian cut-off value for body mass index (BMI), the MAFLD group was further classified into the lean/normal-weight (BMI <23kg/m2 ) and overweight/obese (BMI ≥23kg/m2 ) subgroups. The impact of MAFLD and its subtypes on the cumulative incidence of reflux esophagitis was evaluated using multivariable Cox proportional hazards regression analysis. MAFLD was diagnosed in 26.5% (2416/9100) of patients. Multivariable Cox proportional hazards regression analysis indicated that MAFLD (hazard ratio [HR] 1.2183; 95% confidence interval [CI] 1.0954-1.3550; p=0.0003), hiatal hernia, and aging were independent risk factors for reflux esophagitis. Stratification analysis indicated that cumulative incidence of reflux esophagitis among patients with MAFLD was significantly higher in the lean/normal-weight than in the overweight/obese group (HR 1.3274; 95% CI 1.0043-1.7547; p=0.0466). Among various metabolic factors, visceral adiposity was the only independent metabolic risk factor for reflux esophagitis (HR 2.8331; 95% CI 1.0201-7.8691; p=0.0457) in the lean/normal-weight MAFLD group. MAFLD, in particular lean/normal-weight MAFLD, is independent risk factor for reflux esophagitis. Furthermore, visceral adiposity was identified as the most strong metabolic risk factor for reflux esophagitis in lean/normal-weight patients with MAFLD.

Predictive Factors for Future Onset of Reflux Esophagitis: A Longitudinal Case-control Study Using Health Checkup Records.

Background/AimsAlthough risk factors of reflux esophagitis (RE) have been investigated in numerous cross-sectional studies, little is known about predictive factors associated with future onset of RE. We investigated time courses of clinical parameters before RE onset by a longitudinal case-control study using health checkup records.MethodsWe used health checkup records between April 2004 and March 2014 at 9 institutions in Japan. A multivariate logistic regression analysis was performed to evaluate associations of baseline clinical parameters with RE. The time courses of the clinical parameters of RE subjects were compared with those of non-RE subjects by the mixed-effects models for repeated measures analysis or longitudinal multivariate logistic analysis.ResultsInitial data were obtained from 230 056 individuals, and 2066 RE subjects and 4132 non-RE subjects were finally included in the analysis. Body mass index, alanine aminotransferase, smoking, acid reflux symptoms, hiatal hernia, and absence of atrophic gastritis at baseline were independently associated with RE. The time courses of body mass index, fasting blood sugar, triglyceride, aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transpeptidase, percentages of acid reflux symptoms, feeling of fullness, and hiatal hernia in the RE group were significantly worse than in the non-RE group.ConclusionsThe RE group displayed a greater worsening of the clinical parameters associated with lifestyle diseases, including obesity, diabetes, hyperlipidemia, and fatty liver for 5 years before RE onset compared with the non-RE group. These results suggest that RE is a lifestyle disease and thus lifestyle guidance to at-risk person may help to prevent RE onset.

Clinical characteristics of reflux esophagitis among patients with liver cirrhosis: a case-control study

Background Reflux esophagitis (RE) can cause esophageal varices bleeding and largely reduce life quality of liver cirrhosis (LC) patients. Aims To clarify the prevalence, severity and risk factors of RE among LC patients. Methods A case-control study that enrolled 420 endoscopy-confirmed LC patients with RE as a case cohort and 409 LC patients without RE as a control group was conducted. Logistic regression was used to determine the risk factors for RE among LC patients. Results The 10-year cumulative incidence rate of RE was 4.79% among the LC patients. The severity of RE among the LC patients was higher than that among the non-LC patients (p<.05). The LC patients with RE patients were older (56 years vs. 53 years) and had higher rates of male patients (77.14% vs. 65.77%), smoking (46.90% vs. 32.76%), alcohol intake (50.24% vs. 41.08%), past endoscopic variceal ligation (EVL) (9.05% vs. 4.65%), endoscopic injection sclerotherapy (EIS) (16.19% vs. 2.69%), hiatus hernia (7.14% vs. 0.13%) and portal vein thrombosis (PVT) (14.05% vs. 4.01%). Logistic regression demonstrated that hiatus hernia, past EIS, PVT, smoking, white blood cell count, age, spleen thickness and platelet (PLT) count were risk factors for RE among the LC patients. Conclusions Patients with LC tended to have severer RE than non-LC patients. The special risk factors of RE among LC patients included past EIS and PVT, which deserved extra attention for hepatologists as well as gastroenterologists to prevent.

Risk of Reflux-Related Symptoms and Reflux Esophagitis after Helicobacter pylori Eradication Treatment in the Japanese Population.

Backgrounds: A meta-analysis of reports primarily from Western countries showed no association between Helicobacter pylori eradication and reflux esophagitis development. The risk of reflux esophagitis may differ among different populations based on H. pylori virulence factors and acid secretion ability. We evaluated the prevalence rates of reflux esophagitis in H.-pylori-positive Japanese subjects and assessed risk factors for reflux esophagitis after eradication. Methods: Among 148 H.-pylori-positive subjects who underwent H. pylori eradication from August 2015 to December 2019, we evaluated the prevalence of reflux esophagitis on endoscopy at 12 months after eradication success and the severity of reflux-related symptoms by the F-scale questionnaire at 2 months after treatment and 12 months after eradication success. Results: The prevalence of reflux esophagitis in H.-pylori-positive patients at entry was 2.0% (3/148). At 12 months after eradication success, the prevalence was 10.8% (16/148) (p < 0.01). In the F scale, the median total score before treatment was 4 (range: 0–49), which significantly decreased to 2 (range: 0–22) (p < 0.01) at 2 months after treatment and 3 (range: 0–23) (p < 0.01) at 12 months after eradication success. Following multivariate analysis, the pretreatment total F-scale score was a risk factor for the development of reflux esophagitis (odds ratio: 1.069, 95% confidence interval: 1.003–1.139, p < 0.01). Conclusions: In this H.-pylori-positive Japanese population, eradication therapy was associated with reflux esophagitis in around 10% of patients, particularly in those with severe reflux-related symptoms at baseline. Reflux-related symptoms may improve throughout the 12 months after successful eradication therapy, irrespective of the development of reflux esophagitis.

Gender-Specific Risk Factors for Reflux Esophagitis in a Predominantly Hispanic Population of a Large Safety-Net Hospital

BackgroundDefining factors associated with severe reflux esophagitis allows for identification of subgroups most at risk for complications of strictures and esophageal malignancy. We hypothesized there might be unique clinical features in patients with reflux esophagitis in a predominantly Hispanic population of a large, safety-net hospital.AimDefine clinical and endoscopic features of reflux esophagitis in a predominantly Hispanic population of a large, safety-net hospital.MethodsThis is retrospective comparative study of outpatients and hospitalized patients identified with mild (Los Angeles Grade A/B) and severe (Los Angeles Grade C/D) esophagitis through an endoscopy database review. The electronic medical record was reviewed for demographic and clinical data.ResultsReflux esophagitis was identified in 382/5925 individuals: 56.5% males and 79.8% Hispanic. Multivariable logistic regression model adjusted for age, gender, race, body mass index (BMI), tobacco and alcohol use, and hospitalization status with severity as the outcome showed an interaction between gender and BMI (p ≤ 0.01). Stratification by gender showed that obese females had decreased odds of severe esophagitis compared to normal BMI females (OR = 0.18, 95% CI = 0.07-0.47; p < 0.01). In males, the odds of esophagitis were higher in inpatient status (OR = 2.84, 95% CI = 1.52 − 5.28; p < 0.01) and as age increased (OR = 1.37, 95% CI = 1.03 − 1.83; p = 0.03).ConclusionsWe identify gender-specific associations with severe esophagitis in a predominantly Hispanic cohort. In females, obese BMI appears to be protective against severe esophagitis compared to normal BMI, while in men inpatient status and increasing age were associated with increased odds of severe esophagitis.

Association between Reflux Esophagitis Incidence and Palmar Hyperhidrosis.

The autonomic dysfunction in palmar hyperhidrosis (PH) includes not only sympathetic overactivity but also parasympathetic impairment. A decrease of parasympathetic tone has been noted in gastroesophageal reflux disease of neonates and adults. Patients with reflux esophagitis have a defective anti-reflux barrier. The association between reflux esophagitis and PH is deliberated in this article. The National Health Insurance Database in Taiwan was used. At first-time visits, PH patients were identified by the International Classification of Disease, 9th Revision, Clinical Modification disease code of 780.8 without endoscopic thoracic sympathectomy. Patients were matched by age and gender as control groups. The reflux esophagitis incidence was assessed using disease codes 530.11, 530.81, and 530.85. The factors related to reflux esophagitis were established by the Cox proportional regression model. The risk of reflux esophagitis in PH patients had a hazard ratio of 3.457 (95% confidence interval: 3.043–3.928) after adjustment of the other factors. We confirmed the association between reflux esophagitis and PH. Health care providers must be alerted to this relationship and other risk factors of reflux esophagitis to support suitable treatments to improve the quality of life of patients.

Prevalence of reflux esophagitis in obese Japanese undergoing bariatric surgery

BackgroundCurrently, the data on the relationship between obesity and gastroesophageal reflux disease (GERD) in Asian populations are scarce.MethodsThe aim of this study is to investigate the prevalence of reflux esophagitis (RE) among obese Japanese patients in each body mass index (BMI) range group. In addition, we aim to investigate the risk factors for RE in obese Japanese patients. The present retrospective cohort study included 674 obese Japanese patients who underwent bariatric surgery between January 2003 and April 2016. The patients were stratified into five groups based on BMI range.ResultsThe mean BMI was 42.7 ± 9.24 kg/m2. The prevalence of RE among each of the groups was as follows: Group 1 (BMI 30–34.9) = 20.7%; Group 2 (BMI 35–39.9) = 24.0%; Group 3 (BMI 40–44.9) = 25.2%; Group 4 (BMI 45–49.9) = 26.7%; and Group 5 (BMI ≥50) = 24.8%. Overall, the prevalence of RE was 24.2% in our study. Furthermore, no significant difference in BMI was noted between the RE and non‐RE groups (43.4 ± 9.3 kg/m2 and 42.5 ± 10.2 kg/m2, respectively; p = 0.24). According to the multivariate logistic regression model, gender, Helicobacter pylori infection status, GERD‐related symptoms, and hiatal hernia were significantly correlated with RE.ConclusionOur study shows that the prevalence of RE in severely obese Japanese patients was significantly higher than the average prevalence of RE in Japan. However, the prevalence of RE did not increase with BMI in our cohort.

Risk factors for reflux esophagitis after eradication of Helicobacter pylori

Objective: While there is an association between successful eradication of Helicobacter pylori (HP) and reflux esophagitis (RE), risk factors associated with RE remain obscure. The aim of this study is to determine risk factors associated with the development of RE after HP eradication.Materials and methods: Among all patients treated with successful HP eradication from 2008 to 2016, we retrospectively analyzed those who were free from RE at initial esophagogastroduodenoscopy (EGD) and who were followed up with EGD after eradication. Patients were classified according to the presence or absence of RE at the follow-up EGD. RE was defined as mucosal breaks proximal to the squamous-columnar junction. Demographic data, underlying diseases, medications and endoscopic findings at the initial EGD were compared between patients with and without RE.Results: Among 1575 patients, 142 (9.0%) had RE at the follow-up EGD. The time interval from HP eradication until EGD ranged from 4 to 24 months. The endoscopic grade of RE was higher in males than in females. Multivariate analysis revealed that male sex (odds ratio [OR], 1.51; 95% confidence interval [CI], 1.04–2.24), body mass index ≥25 kg/m2 (OR, 2.91; 95% CI, 2.00–4.22), use of calcium channel blockers (OR, 1.70; 95% CI, 1.12–2.55), and hiatal hernia (OR, 3.46; 95% CI, 2.41–5.00) were associated with the development of RE.Conclusions: Calcium channel blocker use was found to be a risk factor for the development of RE after eradication of HP.

Analysis of risk factors for reflux esophagitis based on clinical big data platform

Analysis of risk factors for reflux esophagitis based on clinical big data platform

Long-term effect of Helicobacter pylori eradication on prevalence of reflux esophagitis.

This study aimed to clarify the long-term effect of Helicobacter pylori eradication on the prevalence of reflux esophagitis (RE). We enrolled 8123 individuals (male 5286, female 2837; mean age 54.2±9.3years) who visited our medical center for an annual checkup between April 2016 and December 2018 and in whom the status of H.pylori infection could be determined. The presence of endoscopically proven RE was determined and compared based on that infection status. Reflux esophagitis was observed in 898 subjects (11.1%). The rates of prevalence in subjects without and with H.pylori infection and with a post-eradication status were 14.0%, 3.7%, and 10.1%, respectively (P<0.001). Multiple logistic regression analysis of those positive for RE showed male gender, elevated body mass index, habitual drinking, habitual smoking, larger diaphragmatic hiatus size, and milder gastric mucosal atrophy to be significant risk factors. As compared with H.pylori negative, the odds ratios for H.pylori-positive and post-eradication status were 0.225 and 0.703, respectively. When post-eradication subjects were divided according to duration following eradication, RE prevalence was increased in association with a longer duration. Multiple logistic regression analysis revealed longer duration after H.pylori eradication to be a significant risk factor for RE. The risk of RE developing in individuals following eradication of H.pylori is considered to be lower as compared with those never infected. However, the risk for RE increases as the period following H.pylori eradication is extended.

Gender Specific Differences in Prevalence and Risk Factors for Gastro-Esophageal Reflux Disease.

BackgroundGender-related factors might play an important role in the development of reflux esophagitis (RE) and symptomatic gastro-esophageal reflux disease (GERD). We aimed to evaluate the prevalence and risk factors for RE and symptomatic GERD and determine whether gender specific differences exist.MethodsThis study was conducted on a health cohort consisting of 10,158 participants who underwent comprehensive health screening. Lifestyles and gastrointestinal symptoms were investigated using a self-reported structured questionnaire. Questionnaires about menstrual status were added for the women.ResultsThe prevalence of RE in men was significantly higher than that in women (10.6% vs. 2.0%, P < 0.001); however, symptomatic GERD showed predominance in women (6.2% vs. 2.5%, P < 0.001). Although the prevalence of RE gradually increased with the duration of menopause stratified by decade (P = 0.007), that of symptomatic GERD rapidly increased across the menopausal transit in women. Apart from common risk factors of obesity and current smoking for RE, over 70 years of age in women and hiatal hernia and hypertriglyceridemia in men were significant risk factors. In symptomatic GERD, high somatization was a common risk factor. Excessive alcohol drinking was a significant risk factor in men, but not in women.ConclusionThis study showed a predominance of RE in men, but a predominance of symptomatic GERD in women. In women, dynamic increase in the prevalence of GERD is closely related to the menopause conditions and its duration. There are specific risk factors for RE and symptomatic GERD according to gender differences.
