Prevalence of Gastroesophageal Reflux Disease (GERD) in Dyspepsia Patients in Primary Referral Hospital

Background: Gastroesophageal reflux disease (GERD) is caused by reflux of stomach contents into the esophagus and give the typical symptoms as heartburn. The prevalence of GERD was vary around the world. Prevalence of GERD by endoscopy in Jakarta was 22.8%. Limited data exist to determine the prevalence and related factors of gastroesophageal reflux disease (GERD) in the population without alarm symptoms. Validated GERDq questionnaire can be used easily to diagnose GERD in primary health care. This study aims to know the prevalence of GERD and related factors.Method: This cross-sectional study was conducted in adult dyspepsia patients at General Hospital District of Cilincing from January to March 2016. A validated GERDq questionnaire and a single proportion sample size calculation were used. Results: The prevalence of GERD was 49%, in elderly participants the prevalence was 44%. Of the 104 consecutive participants, 33.7% were male and 66.3% were female. The mean age was 47.6 ± 15.4 years old. The rate of GERD was higher in females than in males (53 vs. 40%, p = 0.189), increased as the age of the participants increased (p = 0.059) and also increased as the body mass index (BMI) of the participants increased (p 0.05). GERD was present in 50% of active or former smokers (p 0.05), 33.3% of daily coffee drinkers (p 0.05), 56.2% of active or former alcohol consumers (p 0.05), and 57.4% of daily tea drinkers (p = 0.049).Conclusion: The prevalence of GERD in dyspeptic patient was still high. There is a relation between GERD and tea consumption.

Effects of Lixisenatide Versus Liraglutide (Short- and Long-Acting GLP-1 Receptor Agonists) on Esophageal and Gastric Function in Patients With Type 2 Diabetes

Short-acting glucagon-like peptide 1 receptor agonists (GLP-1 RAs) decelerate gastric emptying more than long-acting GLP-1 RAs. Delayed gastric emptying is a risk factor for gastroesophageal reflux disease. We aimed to measure esophageal reflux and function as well as gastric emptying and acid secretion during treatment with short-acting (lixisenatide) and long-acting (liraglutide) GLP-1 RAs. A total of 57 subjects with type 2 diabetes were randomized to a 10-week treatment with lixisenatide or liraglutide. Changes from baseline in the number of reflux episodes during 24-h pH registration in the lower esophagus, lower esophagus sphincter pressure, gastric emptying (13C-sodium octanoate acid breath test), and gastric acid secretion (13C-calcium carbonate breath test) were analyzed. Gastric emptying half-time was delayed by 52 min (Δ 95% CI 16, 88) with lixisenatide (P = 0.0065) and by 25 min (3, 46) with liraglutide (P = 0.025). There was no difference in the number of reflux episodes (mean ± SEM 33.7 ± 4.1 vs. 40.1 ± 5.3 for lixisenatide and liraglutide, respectively, P = 0.17) or the extent of gastroesophageal reflux (DeMeester score) (35.1 ± 6.7 vs. 39.7 ± 7.5, P = 0.61), with similar results for the individual GLP-1 RAs. No significant changes from baseline in other parameters of esophageal motility and lower esophageal sphincter function were observed. Gastric acidity decreased significantly by -20.7% (-40.6, -0.8) (P = 0.042) with the GLP-1 RAs. Lixisenatide exerted a more pronounced influence on gastric emptying after breakfast than liraglutide. Neither lixisenatide nor liraglutide had significant effects on esophageal reflux or motility. Gastric acid secretion appears to be slightly reduced by GLP-1 RAs.

Correction: Prevalence of Barrett’s esophagus in obese patients undergoing pre-bariatric surgery evaluation: a systematic review and meta-analysis

Introduction Obesity is a known risk factor for gastroesophageal reflux disease (GERD), Barrett’s esophagus (BE), and esophageal adenocarcinoma (EAC). Obese patients routinely undergo preoperative esophagogastroduodenoscopy (EGD) before bariatric procedures. We aimed to assess the prevalence of BE in this patient population. Methods We conducted a comprehensive literature search ending in March 2019. Search results were imported into covidence.org and screened by two independent reviewers. Heterogeneity was assessed using I 2 and Q statistics and publication bias using funnel plots and the Orwin fail-safe test. Random-effects modeling was used in all analyses. Results Of 4087 citations, 77 were reviewed in full text and 29 were included in the final analysis based on our predetermined inclusion/exclusion criteria. A total of 13 434 patients underwent pre-bariatric surgery EGD. The pooled prevalence of BE using random-effects modeling was 0.9 % (95 % confidence interval [CI] 0.7 % – 1.3 %); P < 0.001; I 2 = 58 %, Q = 67). In meta-regression analyses, controlling for sex and GERD, we found a positive association between mean body mass index (BMI) and the prevalence of BE (β = 0.15 [95 %CI 0.02 – 0.28]; P = 0.03). A linear relationship between the prevalence of BE and the prevalence of GERD was also noted (β = 3.9 [95 %CI 0.4 – 7.5]; P = 0.03). Conclusions Obesity has been postulated as a major risk factor for BE, yet we found that the prevalence of BE in morbidly obese patients undergoing preoperative EGD was very low. Therefore, obesity alone may not be a major risk factor for BE.

Gastroesophageal reflux disease in a typical African population: a symptom-based multicenter study

BackgroundThe prevalence of gastroesophageal reflux disease (GERD) in Africa is not known but is believed to be increasing because of demographic and epidemiologic transition. The main objectives of this study were to determine the prevalence and risk factors of GERD, and its degree of overlap with dyspepsia and irritable bowel syndrome (IBS) in Nigeria, a typical African population.MethodsThis was an observational, cross-sectional and descriptive study of adult Nigerians. Diagnosis of GERD was by means of the gastroesophageal reflux disease questionnaire (GERDQ) while the diagnosis of dyspepsia and IBS was based on the Rome III criteria for the diagnosis of functional gastrointestinal disorders. The GERDQ and Rome III questionnaires for dyspepsia and IBS were merged into a composite questionnaire and administered to the study participants who were recruited with a multi-stage sampling technique.ResultsOut of 3520 subjects who participated in the study across the country, 269 (7.6%) satisfied the diagnostic criteria for GERD, while 107 (3.0%) had GERD associated with significant impairment of quality of life. Risk factors of GERD (represented by odds ratios) were age 1.014(95% CI: 1.006–1.022), use of analgesics 1.461 (95% CI: 1.060–2.025), and use of herbs 1.318 (95% CI: 1.020–1.704). Overlap of GERD with dyspepsia and/or IBS was observed in over 50% of cases.ConclusionsThe prevalence of GERD in this study is 7.6%. Age, use of analgesics and use of herbs increase the risk, albeit minimally. A high degree of overlap with dyspepsia and IBS exists in Nigerian patients with GERD.

Predictive Factors of Gastroesophageal Reflux Disease in Bariatric Surgery: a Controlled Trial Comparing Sleeve Gastrectomy with Gastric Bypass.

To evaluate the impact of laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric bypass (LRYGB) on gastroesophageal reflux disease (GERD) in patients with obesity. Patients with class II or III obesity were treated with LSG or LRYGB. Procedure choice was based on patients and surgeon preferences. GERD symptoms, endoscopy, barium swallow X-ray, esophageal manometry, and 24-h pH monitoring were obtained before and 1 year after surgery. Seventy-five patients underwent surgery (83% female, 39.3 ± 12.1 years, BMI of 41.5 ± 5.1 kg/m2): 35 (46.7%) had LSG and 40 (53.3%) LRYGB. LSG patients had lower BMI (40.3 ± 4.0 kg/m2 vs. 42.7 ± 5.7 kg/m2; p = 0.041) and trend toward lower prevalence of GERD (20% vs. 40%; p = 0.061). One year after surgeries, GERD was more frequent in LSG patients (74% vs. 25%; p < 0.001) and all LSG patients with preoperative GERD continue to have GERD postoperatively. De novo GERD occurred in 19 of 28 (67.9%) of LSG patients and 4 of 24 (16.7%) patients treated with LRYGB (OR 10.6, 95%CI 2.78-40.1). Independent predictors for post-operative GERD were as follows: LSG (OR 12.3, 95%CI 2.9-52.5), preoperative esophagitis (OR 8.5, 95% CI 1.6-44.8), and age (OR 2.0, 95%CI 1.1-3.4). One year after surgery, persistent or de novo GERD were substantially more frequent in patients treated with LSG compared with LRYGB. LSG was the strongest predictor for GERD in our trial. Preoperative counseling and choice of bariatric surgical options must include a detailed assessment and discussion of GERD-related surgical outcomes.

Prevalence and Risk Factors of Gastroesophageal Reflux Disease in Southwestern Saudi Arabia.

BackgroundGastroesophageal reflux disease (GERD) is one of the most common gastrointestinal disorders that has substantial health and economic consequences. Several modifiable risk factors are associated with GERD, hence we conducted the present study to assess the prevalence and risk factors of GERD in a previously understudied population of southwestern Saudi Arabia.MethodsA cross-sectional study was carried out to calculate the prevalence of GERD and assess its risk factors. A structured self-administered questionnaire was distributed on a random sample of 853 participants from Jazan region, Saudi Arabia. The questionnaire consisted of questions on the participants’ sociodemographic and lifestyle characteristics. The presence of GERD was detected using the GERD questionnaire (GerdQ). Data were analyzed using descriptive statistics and chi-square test, with a significance level of P < 0.05 or P < 0.01.ResultsThe study included 853 participants; 69.1% males and 30.9% females. The proportion of participants who scored >8 on the GerdQ (had GERD) was 32.2%. GERD was associated with age (P < 0.01), marital status (P < 0.01), employment status (P < 0.01), fast food intake (P < 0.01), analgesics use (P < 0.01), and smoking (P < 0.01). GERD was more common among Khat chewers compared to non-Khat chewers (P < 0.05) and showed a significant association with the frequency of Khat use.ConclusionThe results show a high prevalence of GERD in the general population of Southwestern Saudi Arabia. Several sociodemographic and lifestyle characteristics were associated with the disease.

Association between skeletal muscle attenuation and gastroesophageal reflux disease: A health check-up cohort study

Sarcopenia is defined as skeletal muscle attenuation and has an association with metabolic syndrome. Metabolic syndrome, which includes obesity, is one of known predictive factors for gastroesophageal reflux disease (GERD). This study aimed to elucidate the association between sarcopenia and GERD. We retrospectively reviewed electronic medical records of 8,218 patients who were performed an upper gastrointestinal endoscopy at check-up center of the Gangnam Severance Hospital. GERD was diagnosed by endoscopic findings. Erosive reflux disease (ERD) included Barrett's esophagus and reflux esophagitis, with the exception of minimal change esophagitis. Sarcopenia was defined by appendicular skeletal muscle (skeletal muscle in the upper and lower limbs). Sarcopenic obesity was defined as the presence of both sarcopenia and obesity. Associations between sarcopenia and GERD, as well as between sarcopenic obesity and ERD, were analyzed. A total of 3,414 patients were diagnosed with GERD, and 574 (16.8%) had sarcopenia. Sarcopenia was independent predictive factor for GERD (odds ratio [OR] = 1.170, 95% confidence interval [CI]: 1.016–1.346, P = 0.029). In addition, male sex, smoking, alcohol, and diet, including sweets and fatty food, had a significant association with GERD. A total of 1,423 (17.3%) of 8,218 patients were diagnosed with ERD, and 302 (21.2%) had sarcopenia. Male sex, smoking, and fatty food consumption had a significant association with ERD. Moreover, sarcopenia (OR = 1.215, 95% CI: 1.019–1.449, P = 0.030), obesity (OR = 1.343, 95% CI: 1.163–1.552, P < 0.001), and sarcopenic obesity (OR = 1.406, 95% CI: 1.195–1.654, P < 0.001) were independent predictive factors for ERD. Sarcopenia is associated with GERD, and sarcopenic obesity may be predictive factor for ERD.

Diagnosis of Obesity and Related Biomarkers

Obesity is associated with various comorbidities, such as type II diabetes, hypertension, dyslipidemia, and cardiovascular disease. Gastrointestinal complications are also frequent and obesity is a direct cause of nonalcoholic fatty liver disease, and are risk factors for gastroesophageal reflux disease, pancreatitis, gallstone disease, diarrhea, dyssynergic defection, and various gastrointestinal cancers. Diagnosis is usually made by measuring body mass index (BMI). Although BMI is correlated with body fat mass, it may overestimate subjects with high muscle mass and underestimate subjects with low muscle mass. Co-measurement of waist circumference as a reflection of abdominal obesity for subjects with BMIs ranging from 25 to 35 kg/m2 has been recommended; however, it is still an anthropometric diagnosis that does not clearly discriminate subjects at risk for developing comorbidities. Biomarkers reflect the underlying biological mechanisms of obesity and can be used to characterize the obesity phenotype (i.e., at high risk for disease development) as well as a target for disease-causing factors. In this article, we describe the conventional diagnosis, biomarkers of obesity, and current challenges.

A population-based study on prevalence and risk factors of gastroesophageal reflux disease in the Tibet Autonomous Region, China.

ObjectiveTo investigate the prevalence and risk factors of gastroesophageal reflux disease (GERD) in the Tibet Autonomous Region, China.MethodsIn this cross-sectional study, a stratified random sampling method was used for collecting samples in the Tibet Autonomous Region. A total of 10,000 individuals were selected from October 2016 to June 2017. A previously-published, validated questionnaire including six items related to the symptoms of GERD was used for evaluating GERD. In addition, basic demographic data, lifestyle, dietary habits, medical history and family history of GERD were investigated to identify risk factors of GERD.ResultsA total of 5,680 completed questionnaires were collected and analyzed. The prevalence of GERD in this area was 10.8%. Age (30–40 years vs. under 18 years, odds ratio (OR): 3.025; 40–50 years vs. under 18 years, OR: 4.484), education level (high school vs. primary, OR: 0.698; university vs. primary, OR: 2.804), ethnic group (Han vs. Tibetan, OR: 0.230; others vs. Tibetan, OR: 0.304), altitude of residence (4.0–4.5 km vs. 2.5–3.0 km, OR: 2.469), length of residence (<5 years vs. ≥5 years, OR: 2.218), Tibetan sweet tea (yes vs. no, OR: 2.158), Tibetan barley wine (yes vs. no, OR: 1.271), Tibetan dried meat (yes vs. no, OR: 1.278) and staying up late (yes vs. no, OR: 1.223) were significantly (all P < 0.05) and independently associated with GERD.ConclusionsThe prevalence of GERD is high in the Tibet Autonomous Region, China. Geographic conditions, ethnic group and lifestyle are risk factors for GERD.

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.

Prevalence and risk factors of gastroesophageal reflux disease among Shaqra University students, Saudi Arabia.

Introduction:Gastroesophageal reflux disease (GERD) is one of the most common chronic gastrointestinal disorders in adults, it develops when the stomach contents reflux and rise up into the esophagus as a result from lower esophageal sphincter dysfunction. Stomach acid that touches the lining of the esophagus causes symptoms and complications. The classical symptoms of GERD include heartburn, usually after eating, chest pain, and regurgitation.Aim:To measure the prevalence of gastroesophageal reflux disease and determine its risk factors among the students of Shaqra University.Methods:A cross-sectional study was conducted using a structured questionnaire distributed among Shaqra University students after multistage stratification and random sampling technique to stratify students according to gender and the three main colleges in Shaqra city, Saudi Arabia. The sample size was determined to be 435 with the precision of ± 5% and a 95% confidence interval (CI). The questionnaire included demographic data like age, gender, height and weight, lifestyle, and dietary habits. Statistical data were analyzed using the Statistical Package for Social Sciences (SPSS) version 16. Results with a P value of <0.05 were considered statistically significant.Results:A total of 400 [227 (56%) male and 173 (43%) female] participants were evaluated. And 95 participants got a gastroesophageal reflux disease questionnaire score of ≥8 thus determining the prevalence of GERD to be 23.8%. Univariate analysis revealed that gender, smoking, familial history of GERD, high body mass index (>25 kg/m2), fast food, tea, carbonated beverages consumption, quick eating, and sleeping within 1 hour of dinner are associated with symptomatic GERD (P < 0.05).Conclusion:The results show a high prevalence of GERD in Shaqra university students and the presence of many modifiable risk factors which merits the conduction of public health campaigns to raise awareness about the disease and its risk factors.

Weight Loss as a Nonpharmacologic Strategy for Erosive Esophagitis: A 5-Year Follow-up Study.

Background/AimsObesity is a risk factor for gastroesophageal reflux disease (GERD), with several studies demonstrating positive associations between body mass index (BMI) and GERD symptoms. However, little is known about the effect of BMI changes on erosive esophagitis (EE). In this study, we investigated whether BMI reduction could resolve EE.MethodsA retrospective cohort study was performed to assess the natural course of EE according to changes in BMI. Participants undergoing health check-ups from 2006 to 2012 were enrolled, and 1,126 subjects with EE were included. The degree of esophagitis was measured by upper endoscopy and serially checked over a 5-year follow-up. Logistic regression and Cox proportional hazards models were used to investigate the association between BMI reduction and EE resolution.ResultsSubstantial weight loss is associated with EE resolution. The adjusted odds ratio for EE resolution was 1.44 (95% confidence interval [CI], 1.09 to 1.92) among participants with a decrease in BMI compared to those with no decrease in BMI. The EE resolution rate was related to the degree of BMI reduction. The effect of weight loss on EE resolution was higher among subjects who lost more weight. Compared with subjects with no decrease in BMI, the hazard ratios for EE resolution were 1.09 (95% CI, 0.89 to 1.35), 1.31 (95% CI, 1.01 to 1.72) and 2.12 (95% CI, 1.44 to 3.12) in subjects with BMI reductions of ≤1, 1–2, and >2 kg/m2, respectively.ConclusionsEE resolution is associated with a decrease in BMI, and weight loss is potentially an effective GERD treatment.

Evaluation of gastroesophageal reflux disease and related factors in seasonal agricultural workers

As gastroesophageal reflux disease affects various aspects of health and consumes considerable resources, it is important to know its prevalence in seasonal agricultural workers. This study was conducted to evaluate the frequency of gastroesophageal reflux disease and related factors in seasonal agricultural workers.The study is a cross-sectional study conducted on seasonal agricultural workers working in rural Eskiþehir. 536 of seasonal agricultural workers were formed the working group. The prevalence of gastroesophageal reflux disease was evaluated with the National Institutes of Health Patient-Reported Outcomes Measurement Information System Gastroesophageal Reflux Disease Scale. Multivariate logistic regression analysis was used in multivariate analysis.Of the study group, 62.5% were female and the age of the study group ranged from 18 to 92 years. The prevalence of gastroesophageal reflux disease among seasonal agricultural workers were detected as 82.8%. Gender, age, monthly average income, and body mass index were all found as important risk factors for gastroesophageal reflux disease in our study.Also, it was detected a considerable amount of gastroesophageal reflux disease in seasonal agricultural workers.Family income status has to be improved and struggle against overweight to decrease the prevalence of gastroesophageal reflux disease in seasonal agricultural workers.

Gastroesophageal reflux disease and its related factors among women of reproductive age: Korea Nurses\u2019 Health Study

BackgroundRecently, the number of patients diagnosed with gastroesophageal reflux disease (GERD) has increased in Korea. Risk factors of GERD include age, sex, medication use, lack of physical exercise, increased psychological stress, low or high body mass index (BMI), unhealthy eating habits, increased alcohol consumption, and cigarette smoking. However, few studies examined the major factors affecting GERD in women of childbearing age. Therefore, this study assessed the risk factors of GERD among 20,613 female nurses of reproductive age using data from the Korea Nurses’ Health Study.MethodsParticipants were recruited from July 2013 to November 2014. They provided their history of GERD 1 year prior to data collection, along with information on their demographic characteristics, health-related behaviors, diet, medical history, and physical and psychological factors. Of the total sample, 1184 individuals with GERD diagnosed in the year prior to the study were identified. Propensity score matching was used for analysis.ResultsCigarette smoking, increased alcohol consumption, low or high BMI, depression, and increased psychosocial stress were associated with the prevalence of GERD among Korean young women. Multivariate ordinal logistic regression analysis revealed significant positive relationships between GERD and being a former smoker; having a low (< 18.5 kg/m2) or high BMI (> 23 kg/m2); and having mild, moderate, moderately severe, and severe depression.ConclusionsSmoking, BMI, and depression were associated with GERD. To reduce this risk among female nurses, intervention strategies are required to help nurses maintain a normal weight and manage their depression.

Risk factors for gastroesophageal reflux disease and analysis of genetic contributors.

Gastroesophageal reflux disease (GERD) is a common gastrointestinal disorder with an increasing prevalence. GERD develops when the reflux of stomach contents causes troublesome typical and atypical symptoms and/or complications. Several risk factors of GERD have been identified and evaluated over the years, including a considerable amount of genetic factors. Multiple mechanisms are involved in the pathogenesis of GERD including: (1) motor abnormalities, such as impaired lower esophageal sphincter (LES) resting tone, transient LES relaxations, impaired esophageal acid clearance and delayed gastric emptying; and (2) anatomical factors, such as hiatal hernia and obesity. Genetic contribution seems to play a major role in GERD and GERD- related disorders development such Barrett’s esophagus and esophageal adenocarcinoma. Twin and family studies have revealed an about 31% heritability of the disease. Numerous single-nucleotide polymorphisms in various genes like FOXF1, MHC, CCND1, anti-inflammatory cytokine and DNA repair genes have been strongly associated with increased GERD risk. GERD, Barrett’s esophagus and esophageal adenocarcinoma share several genetic loci. Despite GERD polygenic basis, specific genetic loci such as rs10419226 on chromosome 19, rs2687201 on chromosome 3, rs10852151 on chromosome 15 and rs520525 on the paired related homeobox 1 gene have been mentioned as potential risk factors. Further investigation on the risk genes may elucidate their exact function and role and demonstrate new therapeutic approaches to this increasingly common disease.

Problems of nociception in gastroesophageal reflux disease: diagnostics and treatment of irritated oesophagus.

The following factors of gastroesophageal reflux disease (GERD) pathogenesis are addressed in the abstract: activation of nociceptors, hyperexpression of pro-inflammatory cytokines and increase of functional activity of immune competent cells. The current classification of GERD is given which is based on identification of 4 phenotypes of the disease according to diagnostic criteria and prognosis of treatment effectiveness. Importance of pH-impedance monitoring in GERD diagnostics is demonstrated based on its primary significance for identification of reflux nature and determination of relationship between GERD symptoms and reflux. The diagnostics criteria of functional heartburn and hypersensitive; oesophagus according to Rome IV criteria (2016) are presented. The data of the private investigation are demonstrated according to which irritated oesophagus was observed in 26.2% of healthy persons and in 24.2% of GERD patients with endoscopic or pH-metric symptoms of the disease. Implication of oesophagus clearance disorder in GERD pathogenesis has been pointed out. An overview of the current literature data about effectiveness of surgical treatment in patients with different GERD phenotypes and also assessment of clinical effectiveness of long-term treatment with PPI are given. Advantages of anti-secretory drug of the last generation rabeprazole in different patient groups and possibilities of its use in all GERD phenotypes have been discussed.
