Abstract
INTRODUCTION The association between omeprazole and hypertension is poorly documented. The summary of product characteristics of omeprazole approved by major regulators did not mention hypertension as an adverse drug event. Triggered by a locally reported case, this study was conducted to assess the possible causal relationship between omeprazole and hypertension. METHODS Globally reported cases of hypertension following use of omeprazole submitted to the World Health Organization global database, VigiBase, were retrieved on 5 March 2024 and analyzed descriptively. Besides this, a literature search was made to identify preclinical, clinical, and epidemiological information on the association between omeprazole and hypertension or increased blood pressure using different data sources. Relevant information, gathered from different data sources, was finally systematically organized into an Austin Bradford-Hill causality assessment framework to assess the causal relationship between omeprazole and hypertension. RESULTS VigiBase indicated a total of 1043 cases of hypertension related to omeprazole from 36 different countries. In the global database, a statistical signal was triggered (IC025: 0.12) on association of omeprazole and hypertension. From the 1043 cases, 65.0% and 10.6% were reported as 'serious' and 'fatal', respectively. Hypertension resolved following withdrawal of omeprazole in 85 cases and recurred after re-introduction of the suspect drug in 14 cases. In 225 cases, omeprazole was the only suspected drug, while in 122 cases, omeprazole was the sole drug administered. When only these 122 cases were considered, 29 cases had positive dechallenge, four cases were with positive rechallenge and the median time-to-onset was 2 days. Literature search identified a possible biological mechanism and some experimental evidence that indicates omeprazole could possibly cause hypertension. CONCLUSION Currently available totality of evidence suggests there is a possible causal relationship between omeprazole and hypertension. Hence, it is recommended to monitor and report any incidence of hypertension related to omeprazole, and further epidemiological studies are recommended to corroborate the suggested causal association.

Abstract
Gastroesophageal reflux disease (GERD) is a prevalent global health concern with a rising incidence. Various risk factors, including obesity, hiatal hernia, and smoking, contribute to its development. Recent research suggests associations between GERD and metabolic syndrome, cardiac diseases, and hypertension (HTN). Mechanisms linking GERD to HTN involve autonomic dysfunction, inflammatory states, and endothelial dysfunction. Furthermore, GERD medications such as proton-pump inhibitors may impact blood pressure regulation. Conversely, antihypertensive medications like beta-blockers and calcium channel blockers can exacerbate GERD symptoms. While bidirectional causality exists between GERD and HTN, longitudinal studies are warranted to elucidate the precise relationship. Treatment of GERD, including anti-reflux surgery, may positively influence HTN control. However, the interplay of lifestyle factors, comorbidities, and medications necessitates further investigation to comprehensively understand this relationship. In this editorial, we comment on the article published by Wei et al in the recent issue of the World Journal of Clinical Cases. We evaluate their claims on the causal association between GERD and HTN.

J Stroke Cerebrovasc Dis 2024; 33:107612. [PMID: 38309380 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107612] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 01/24/2024] [Accepted: 01/29/2024] [Indexed: 02/05/2024] Open
Abstract
OBJECTIVES Previous observational studies have suggested that gastroesophageal reflux disease (GERD) increases the risk of stroke, but the specific underlying mechanisms are unclear. We investigated the causal associations of GERD with stroke and its subtypes using Mendelian randomization (MR), and evaluated the potential mediating effects of modifiable stroke risk factors in the causal pathway. METHODS Genetic instrumental variables for GERD were extracted from the latest genome-wide association study (GWAS) summary level data. We initially performed two-sample MR to examine the association of GERD with stroke and its subtypes, including ischemic stroke, intracranial hemorrhage, and the major subtypes of ischemic stroke. Two-step MR was further employed to investigate the mediating effect of 15 risk factors in the causal pathway. RESULTS We found significant causal associations of genetically predicted GERD with increased risk of stroke (OR: 1.22 95% CI: 1.126-1.322), ischemic stroke (OR: 1.19 95% CI: 1.098-1.299), and large-artery stroke (OR: 1.49 95% CI: 1.214-1.836). Replication and sensitivity analyses yielded consistent effect directions and similar estimates. Further mediation analyses indicated that hypertension (HTN), systolic blood pressure (SBP), and type 2 diabetes (T2D) mediated 36.0%, 9.0%, and 15.8% of the effect of GERD on stroke; 42.9%, 10.8%, and 21.4% for ischemic stroke, and 23.3%; 7.9%, and 18.7% for large-artery stroke, respectively. CONCLUSIONS This study supports that GERD increases susceptibility to stroke, ischemic stroke, and large-artery stroke, and is partially mediated by HTN, SBP, and T2D.

Abstract
BACKGROUND Clinical studies have reported that patients with gastroesophageal reflux disease (GERD) have a higher prevalence of hypertension. AIM To performed a bidirectional Mendelian randomization (MR) analysis to investigate the causal link between GERD and essential hypertension. METHODS Eligible single nucleotide polymorphisms (SNPs) were selected, and weighted median, inverse variance weighted (IVW) as well as MR egger (MR-Egger) regression were used to examine the potential causal association between GERD and hypertension. The MR-Pleiotropy RESidual Sum and Outlier analysis was used to detect and attempt to reduce horizontal pleiotropy by removing outliers SNPs. The MR-Egger intercept test, Cochran's Q test and "leave-one-out" sensitivity analysis were performed to evaluate the horizontal pleiotropy, heterogeneities, and stability of single instrumental variable. RESULTS IVW analysis exhibited an increased risk of hypertension (OR = 1.46, 95%CI: 1.33-1.59, P = 2.14E-16) in GERD patients. And the same result was obtained in replication practice (OR = 1.002, 95%CI: 1.0008-1.003, P = 0.000498). Meanwhile, the IVW analysis showed an increased risk of systolic blood pressure (β = 0.78, 95%CI: 0.11-1.44, P = 0.021) and hypertensive heart disease (OR = 1.68, 95%CI: 1.36-2.08, P = 0.0000016) in GERD patients. Moreover, we found an decreased risk of Barrett's esophagus (OR = 0.91, 95%CI: 0.83-0.99, P = 0.043) in essential hypertension patients. CONCLUSION We found that GERD would increase the risk of essential hypertension, which provided a novel prevent and therapeutic perspectives of essential hypertension.

Abstract
Erosive esophagitis (EE) is the part of gastroesophageal reflux disease (GERD) spectrum and may progress to esophageal adenocarcinoma. Due to its progressivity and unclear prevalence, we aim to identify the factors contributing in EE to decide the need for further examination. We performed a PRISMA 2020-based systematic search through PubMed and other resources up to June 2, 2022. Study quality was assessed using the Newcastle-Ottawa Scale (NOS). The odds ratio (OR) of each factor and worldwide prevalence of EE were measured. There are 114 observational studies included with a total of 759,100 participants. Out of 29 factors, the significant risk factors are age ≥ 60 y.o. (OR 2.03 [1.81-2.28]), White/Caucasian (OR 1.67 [1.40-1.99]), unmarried (OR 1.08 [1.03-1.14]), having GERD ≥ 5 years (OR 1.27 [1.14-1.42]), general obesity (OR 1.78 [1.61-1.98]), central obesity (OR 1.29 [1.18-1.42]), diabetes mellitus (DM) (OR 1.24 [1.17-1.32]), hypertension (OR 1.16 [1.09-1.23]), dyslipidemia (OR 1.15 [1.06-1.24]), hypertriglyceridemia (OR 1.42 [1.29-1.57]), hiatal hernia (HH) (OR 4.07 [3.21-5.17]), and non-alcoholic fatty liver disease (NAFLD) (OR 1.26 [1.18-1.34]). However, H. pylori infection (OR 0.56 [0.48-0.66]) and atrophic gastritis (OR 0.51 [0.31-0.86]) are protective towards EE. This study demonstrates that age, ethnicity, unmarried, long-term GERD, metabolic diseases, HH, and NAFLD act as risk factors for EE, whereas H. pylori infection and atrophic gastritis act as protective factors. These findings may enable a better understanding of EE and increase greater awareness to address its growing burden.

Abstract
ABSTRACT Despite the availability and advancement of diagnostic and treatments with demonstrated benefits in minimizing cardiovascular morbidity and mortality, hypertension control rates remain suboptimal. Therefore, this research aimed to determine the prevalence of uncontrolled BP in rheumatoid arthritis (RA) patients and understand all potential risk factors for uncontrolled BP.We conducted a cross-sectional study on RA patients in 2 rheumatology clinics in 2 public hospitals in Riyadh. Patients' information such as demographics, comorbidities, drug use, and other clinical data were captured through a review of medical records and supplemented by patient interviews. Multivariate logistic regression was utilized for the analysis to identify the significant factors of uncontrolled BP (systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg).In total, 834 subjects with RA and concomitant BP were involved in this cross-sectional study. The prevalence of uncontrolled BP was found to be 31.65% among all the study population. Multivariate analysis showed that males, subjects above 60 years of age, and smokers had a distinctly higher occurrence of uncontrolled BP. Among the patients with comorbid conditions, those with obesity, hyperlipidemia, diabetes, anemia, cancer, and reflex or gastroesophageal reflux disease also showed a significantly higher risk of uncontrolled BP (P < .05).The rate of uncontrolled BP was found to be alarmingly high in the study population. Age, gender, smoking, diabetes, obesity, hyperlipidemia, cancer, gastroesophageal reflux disease, and osteoporosis are independently linked with lack of BP control.

Abstract
Background and Aim The aim of the present study was to examine the lifestyle‐ and comorbidity‐related determinant factors of the prescription of proton pump inhibitors (PPIs) for patients in whom Helicobacter pylori has been eradicated, and to evaluate the relationship between PPI prescription and the severity of endoscopic esophagitis. Methods This retrospective study included patients who underwent H. pylori eradication from May 2012 to September 2016 at Saiseikai Karatsu Hospital. All patients received upper gastrointestinal endoscopy before H. pylori eradication. Patients with open peptic ulcers and/or malignant diseases were excluded, and a final total of 389 patients were evaluated. Medical records were reviewed to determine the prescription of PPIs after H. pylori eradication, lifestyle‐related factors, and comorbidities. Lifestyle‐related factors were confirmed by a questionnaire. Results PPIs were administered to 124 of 389 patients (31.9%). The only lifestyle‐related risk factor for the prescription of PPIs after H. pylori eradication was older age (P < 0.01). Hypertension increased the prescription of PPIs (P = 0.034). The prescription of PPIs was not influenced by the presence of grade A esophagitis, whereas the PPI prescription rate was significantly increased in patients with grades B/C/D endoscopic esophagitis (P < 0.01). The grade of chronic gastritis before H. pylori eradication had no effect on the prescription of PPIs. Conclusion The lifestyle‐ and comorbidity‐related risk factors for the prescription of PPIs after H. pylori eradication were older age and hypertension, while mild endoscopic esophagitis had no influence on PPI prescription.

Abstract
BACKGROUND The relationship between metabolic syndrome (MetS) and Barrett's esophagus (BE) is still a challenging issue, and inconsistent results have been reported in different studies. Therefore, this study was conducted to determine the relationship between MetS and BE. METHODS In this study, we followed the MOOSE protocol and results were reported according to the PRISMA guidelines. All study steps were performed independently by two authors. If necessary, the dispute was resolved by consultation with a third author. The search strategy is designed to find published studies. Comprehensive search was done in the following databases until July 2019: Cochrane Library, PubMed/Medline, Web of Science, Science Direct, EMBASE, Scopus, CINAHL, EBSCO, and Google Scholar search engine. All analyses were performed using Comprehensive Meta-Analysis Software Ver.2, while p-value lower than 0.05 was considered significant. RESULTS In 14 studies with a sample size of 108,416, MetS significantly increased the risk of BE (OR = 1.354; 95% CI: 1.145-1.600; P < 0.001; Heterogeneity: I2 = 81.95%; P < 0.001). Sensitivity analysis by omitting one study showed that overall estimates are still robust. Subgroup analysis was significant for continent (P < 0.001) and MetS diagnostic criteria (P = 0.043), but was not significant for variables of study type (P = 0.899), study setting (P = 0.115), control groups (P = 0.671) and quality of studies (P = 0.603). The Begg (P = 0.912) and Egger's (P = 0.094) tests were not significant; therefore, the publication bias did not play a role in the results. CONCLUSION MetS increases the risk of BE compared to control groups. The results of this study can help health practitioners by identifying a treatable risk factor for the most important risk factor for esophageal carcinoma (ie, BE). Future studies should examine whether treatment for MetS reduces the risk of BE.

Abstract
Background The prevalence rate of reflux esophagitis (RE) in Asia, including Taiwan, has increased dramatically in recent years. However, few studies have discussed on its relationship with metabolic syndrome (MetS). This study aimed to evaluate the correlation between RE and MetS and its components. Methods We conducted a cross-sectional study during 2013 to 2014 in Taiwan. A total of 4895 subjects who completed upper gastrointestinal endoscopy at the Health Examination Center of Changhua Christian Hospital were enrolled. RE was defined according to the upper gastrointestinal endoscopic findings and MetS was defined according to the Taiwanese criteria. Univariate and multivariate logistic regression analyses were applied to calculate odds ratios and 95% confidence intervals for each variable to assess the associated features for RE. We analyzed the relationship between the number of MetS components and the severity of RE using the chi-square test for trend. Results The prevalence rates of MetS and RE were respectively 28.5 and 59.6%. According to univariate logistic regression analysis, MetS was significantly associated with RE and remained a positive association in multivariate logistic regression analysis (adjusted ORß = 1.251; 95% CI = 1.071–1.462; p = 0.005). Furthermore, among the five MetS components, elevated blood pressure (adjusted ORγ = 1.163; 95% CI = 1.023–1.323; p = 0.021), abdominal obesity (adjusted ORγ = 1.173; 95% CI = 1.020–1.349; p = 0.026) and hyperglycemia (adjusted ORγ = 1.306; 95% CI = 1.142–1.495; p < 0.001) were positively associated with the presence of RE. A weak association was also found between elevated triglycerides and RE after adjusting for age and gender (adjusted ORα = 1.171; 95% CI = 1.022–1.343; p = 0.023). Reduced high-density lipoprotein cholesterol showed no significant difference between groups with and without RE. Older age (≥65 years), male gender, higher body mass index, higher uric acid, smoking, alcohol drinking, and hiatal hernia were found to be significant associated factors for RE. In addition, a dose-response relation between the number of MetS components and the presence of RE was demonstrated in the multivariate analysis. Furthermore, we performed a trend analysis and found the severity of RE got worse as the number of MetS components increased (p < 0.001). Conclusion This study suggests that MetS is significantly related to the presence and the severity of RE.

Chronic lifestyle diseases display seasonal sensitive comorbid trend in human population evidence from Google Trends. PLoS One 2018; 13:e0207359. [PMID: 30540756 PMCID: PMC6291106 DOI: 10.1371/journal.pone.0207359] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2018] [Accepted: 10/30/2018] [Indexed: 02/08/2023] Open
Abstract
Seasonal and human physiological changes are important factors in the development of many diseases. But, the study of genuine seasonal impact on these diseases is difficult to measure due to many other environment and lifestyle factors which directly affect these diseases. However, several clinical studies have been conducted in different parts of the world, and it has clearly indicated that certain groups of population are highly subjected to seasonal changes, and their maladaptation can possibly lead to several disorders/diseases. Thus, it is crucial to study the significant seasonal sensitive diseases spread across the human population. To narrow down these disorders/diseases, the study hypothesized that high altitude (HA) associated diseases and disorders are of the strong variants of seasonal physiologic changes. It is because, HA is the only geographical condition for which humans can develop very efficient physiological adaptation mechanism called acclimatization. To study this hypothesis, PubMed was used to collect the HA associated symptoms and disorders. Disease Ontology based semantic similarity network (DSN) and disease-drug networks were constructed to narrow down the benchmark diseases and disorders of HA. The DSN which was further subjected to different community structure analysis uncovered the highly associated or possible comorbid diseases of HA. The predicted 12 lifestyle diseases were assumed to be “seasonal (sensitive) comorbid lifestyle diseases (SCLD)”. A time series analyses on Google Search data of the world from 2004–2016 was conducted to investigate whether the 12 lifestyle diseases have seasonal patterns. Because, the trends were sensitive to the term used as benchmark; the temporal relationships among the 12 disease search volumes and their temporal sequences similarity by dynamic time warping analyses was used to predict the comorbid diseases. Among the 12 lifestyle diseases, the study provides an indirect evidence in the existence of severe seasonal comorbidity among hypertension, obesity, asthma and fibrosis diseases, which is widespread in the world population. Thus, the present study has successfully addressed this issue by predicting the SCLD, and indirectly verified them among the world population using Google Search Trend. Furthermore, based on the SCLD seasonal trend, the study also classified them as severe, moderate, and mild. Interestingly, seasonal trends of the severe seasonal comorbid diseases displayed an inverse pattern between USA (Northern hemisphere) and New Zealand (Southern hemisphere). Further, knowledge in the so called “seasonal sensitive populations” physiological response to seasonal triggers such as winter, summer, spring, and autumn become crucial to modulate disease incidence, disease course, or clinical prevention.

Abstract
GOALS We assessed the relationship between gastroesophageal reflux disease (GERD) and hypertension and whether antiacid therapy could be used to control blood pressure (BP) on hypertension in patients with GERD. BACKGROUND Gastroesophageal reflux disease (GERD) may provoke cardiovascular disease. Many factors are involved in the development of essential hypertension, but whether GERD has a role needs further study. STUDY Patients with essential hypertension (n=86) were studied by 24-hour continuous BP monitoring and esophageal impedance and pH monitoring. Patients fulfilling the GERD criteria received 14-day therapy with omeprazole (20 mg twice a day), and the effect on BP was studied. RESULTS Of the 86 essential hypertension patients, 38 (44.2%) had GERD. Among these 38 patients, 494 episodes of pathologic reflux (PR), and 684 episodes of high BP were recorded. PR was significantly more common at nighttime especially when supine. Of the 684 episodes of hypertension, 102 (14.9%) were synchronous with PR. GERD patients had significantly higher nocturnal BP than non-GERD patients. Antiacid therapy brought about significant reduction in all esophageal monitoring parameters as well as in BP parameters in GERD patients. CONCLUSIONS This study demonstrated that there is significant correlation between hypertension and GERD. Antiacid therapy can restore normal esophageal pH and help maintain normal BP.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) without symptoms or silent GERD can be easily missed in patients with hypertension. We aimed to investigate the prevalence of GERD, specifically the prevalence of silent GERD in hypertensive patients, and to explore its possible predictors. METHODS Consecutive patients with hypertension referred to the cardiovascular clinic of Suining Central Hospital in 2016 were screened for this study. A Reflux Disease Questionnaire (RDQ) and an esophagogastroduodenoscopy (EGD) were employed for the evaluation of silent GERD. Included patients were divided into silent-GERD group and non-GERD control group. The demographic characteristics and antihypertensive agent prescriptions were collected and compared between the two groups. RESULTS The prevalence of silent GERD and GERD in patients with hypertension was 15.1% and 31.4%, respectively. 66 patients were included in the silent-GERD group, and 298 patients were included in the non-GERD control group. Abdominal obesity and untreated hypertension were positive predictors, while controlled hypertension was a negative predictor for silent GERD. The prescription of calcium channel blockers was not a predictor for it. CONCLUSIONS High prevalence of GERD, specifically silent GERD, could be found in patients with hypertension. Abdominal obesity and untreated hypertension were positive predictors for silent GERD, while controlled hypertension was a negative predictor for it.

Abstract
INTRODUCTION The rise in Gastro-Esophageal Reflux Disease (GERD) prevalence appears to have coincided with a simultaneous increase in the prevalence of diabetes mellitus, hypertension and bronchial asthma amongst the Indian population. Despite being evaluated extensively for their role as a risk factor for GERD, till date this relationship has remained a debatable one. Moreover, literature available on such studies conducted within Indian population remains scarce. AIM The aim of the present study was to examine the risk of developing GERD in patients suffering from diabetes mellitus, hypertension and asthma in a Southern Indian population. The present retrospective, triple cohort and hospital based study was conducted by accessing the patient records from the medical records department of a tertiary care hospital in Southern India. MATERIALS AND METHODS The patient's records were accessed from the year 2011 onwards. Relative Risk (RR) was calculated to determine the risk of development of GERD with every disease. Chi-square test was used to determine the statistical significance of the relationship between each disease and the development of GERD. A p-value of <0.05 was considered statistically significant. RESULTS In view of the time constraints as well as the limitations of the inclusion and exclusion criteria, data pertaining to only 40, 71 and 53 patients in Cohort 1 (diabetics), 2 (hypertensives) and 3 (bronchial asthmatics) respectively could be analyzed in the present study. The relative risk of GERD development was greater than 1 for patients belonging to Cohort 2 and 3, suggesting that the risk of GERD development is higher amongst hypertensives and asthmatics. Surprisingly, the diabetics (Cohort 1) were not associated with a high risk of GERD development. However, the relationship between any of the disease and GERD development was not statistically significant. CONCLUSION The present study found an increased risk of GERD development amongst patients suffering from hypertension and bronchial asthma, but not with diabetes mellitus.

Mortality and cardiovascular diseases risk in patients with Barrett's oesophagus: a population-based nationwide cohort study. Aliment Pharmacol Ther 2017; 45:973-982. [PMID: 28139003 DOI: 10.1111/apt.13962] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2017] [Revised: 01/10/2017] [Accepted: 01/10/2017] [Indexed: 12/18/2022]
Abstract
BACKGROUND Patients with Barrett's oesophagus may be at increased risk of mortality overall, and cardiovascular disease has been suggested as the main underlying cause of death. AIM To examine cause-specific mortality and risk of cardiovascular events among patients with Barrett's oesophagus. METHODS Utilising existing Danish data sources (1997-2011), we identified all patients with histologically verified Barrett's oesophagus (n = 13 435) and 123 526 members of the general population matched by age, sex and individual comorbidities. We calculated cause-specific mortality rates and incidence rates of cardiovascular diseases. We then compared rates between patients with Barrett's oesophagus and the general population comparison cohort, using stratified Cox proportional hazard regression. RESULTS Patients with Barrett's oesophagus had a 71% increased risk of overall mortality. The cause-specific mortality rate per 1000 person-years for patients with Barrett's oesophagus was 8.5 for cardiovascular diseases, 14.7 for non-oesophageal cancers, and 5.4 for oesophageal cancer. Compared to the general population cohort, corresponding hazard ratios were 1.26 (95% confidence interval (CI): 1.15-1.38), 1.77 (95% CI: 1.65-1.90), and 19.4 (95% CI: 16.1-23.4), respectively. The incidence rates of cardiovascular diseases per 1000 person-years for Barrett's oesophagus patients and for persons from the general population cohort, respectively, varied from 0.4 and 0.2 for subarachnoid bleeding (hazard ratio 1.10, 95% CI: 0.87-1.39) to 8.1 and 5.9 for congestive heart failure (hazard ratio 1.33, 95% CI: 1.21-1.46). CONCLUSION Prophylactic measures targeted at cardiovascular diseases and non-oesophageal cancers potentially could be more important than measures against oesophageal cancer, for improving prognosis among patients with Barrett's oesophagus.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) and dyspepsia are highly prevalent in the general population with significant symptom overlap, while the interaction between both remains poorly understood. AIM To examine whether GERD overlapping dyspepsia would have an impact on clinical and psychological features as compared with GERD alone. METHODS We performed a cross-sectional study in a GERD cohort (n = 868) that was previously recruited from a population-based GERD survey (n = 2752). We compared the clinical and psychological factors between patients with and without dyspeptic symptoms "epigastric pain or burning." All participants were evaluated with Reflux Disease Questionnaire score, Pittsburgh Sleep Quality Index score, Taiwanese Depression Questionnaire score, and State-Trait Anxiety Inventory score. Endoscopic findings were classified according to the Los Angeles classification. RESULTS Among the GERD population, 107 subjects had overlapping "epigastric pain or burning" (GERD-D), and 761 did not have these symptoms (GERD alone). GERD-D subjects had more severe GERD symptoms and were more often associated with irritable bowel syndrome (IBS) (OR 3.54, 95% CI 1.92-6.52) as compared subjects with GERD alone. In addition, GERD-D subjects had lower quality of sleep (OR 1.11, 95% CI 1.01-1.21), higher depression (OR 1.06, 95% CI 1.02-1.10), lower blood pressure (OR 0.45, 95% CI 0.22-0.95), and higher serum total cholesterol levels (OR 2.78, 95% CI 1.36-5.67) than GERD alone. CONCLUSIONS GERD-D subjects are characterized with worsening clinical symptoms as well as higher psychosocial, IBS, and metabolic comorbidities, but less erosive esophagitis. Our results indicate that clinical awareness of such overlapping condition would help optimize the management of GERD in clinical practice.

Abstract
This study aims to determine whether successful laparoscopic fundoplication for gastroesophageal reflux disease (GERD) can improve the control of hypertension. We conducted an observational study of GERD patients with hypertension. The esophageal and gastroesophageal symptoms of these patients were successfully treated with laparoscopic fundoplication, as measured by the reduced GERD symptoms and proton pump inhibitor consumption. A hypertension control scale was used to classify the use of antihypertensive medications and the quality of blood pressure control before and after anti-reflux surgery.Wilcoxon signed-ranks test was used for the statistical analyses. Seventy GERD patients were included in the analysis and followed up for a mean period of 3.5 ± 1.4 years. Prior to surgery, all participating patients were taking at least one class of antihypertensive medication, and 56 patients (80%) had intermittently high blood pressure. After surgery, the mean number of antihypertensive medication classes per patient was significantly reduced from 1.61 ± 0.77 pre-procedure to 1.27 ± 0.88 post-procedure (P < 0.001). The blood pressure of 48 of the 56 cases (86%) with preoperative intermittent high blood pressure returned to normal post procedure. A total of 50 patients (71%) recorded improvements on the hypertension control scale, with the overall mean score decreasing from 3.1 ± 1.0 preprocedure to 1.4 ± 1.0 post-procedure (P < 0.001). Therefore, successful laparoscopic fundoplication may result in better blood pressure control in some hypertensive GERD patients. This result suggests a possible connection between gastroesophageal reflux and hypertension.

Abstract
BACKGROUND Few studies have examined the association between metabolic syndrome and Barrett's oesophagus (BO). Whether metabolic syndrome confers a risk greater than the sum of its components is unknown. AIM To investigate associations between metabolic syndrome, its components and BO in white males. METHODS We conducted a case-control study among eligible symptomatic patients scheduled for elective oesophagogastroduodenoscopy and a sample of patients eligible for screening colonoscopy recruited at primary care clinics. Metabolic syndrome was defined as the presence of at least three of: high waist-to-hip ratio (WHR), hypertriglyceridaemia, low high-density lipoprotein cholesterol, hypertension or diabetes. We used multivariate logistic regression to calculate odds ratios (OR) and 95% confidence intervals (95% CI). RESULTS There were 244 BO cases, 209 colonoscopy and 615 endoscopy controls. Comparing BO cases with all controls, metabolic syndrome was significantly associated with BO (OR = 1.59, 95% CI 1.05-2.40) and there was a dose effect with increasing number of metabolic syndrome components (Ptrend <0.001); when all five components were present, the OR was 2.61 (95% CI 1.14-5.99). We found that among the components, high WHR, hypertension and hypertriglyceridaemia were associated with increased risk of BO. When we compared cases with the control groups separately, metabolic syndrome was associated with BO for comparisons with endoscopy controls (OR = 1.67, 95% CI 1.10-2.55) but not colonoscopy controls (OR = 0.87, 95% CI 0.49-1.54). Associations with individual components also depended on the comparison group. CONCLUSIONS Metabolic syndrome is associated with an increased risk of Barrett's oesophagus in men undergoing endoscopy. Metabolic syndrome may confer additional risk of Barrett's oesophagus separate from obesity.

Abstract
Barrett's esophagus (BE) is a premalignant condition of esophageal adenocarcinoma (EAC). Although the incidence of BE has risen rapidly in the West, it is rare in Asia despite a recent increase in the prevalence of gastroesophageal reflux disease. Controversies over the definition of BE are presented because most cases show short-segment BE, especially ultra-short BE, in Asia. Here we review possible risk factors for the development of EAC, particularly possible roles of ethnicity, specialized intestinal metaplasia (SIM), BE length, and environmental factors, such as Helicobacter pylori infection and obesity. Additionally, we summarize recent studies on the effect of chemoprevention including proton pump inhibitors, nonsteroidal anti-inflammatory drugs or aspirin in order to reduce the risk of neoplastic progression in BE patients. Although substantial knowledge of risk factors of dysplasia/EAC in BE is shown, the risk for neoplastic development may be influenced by geographic variation, study population, the presence or absence of SIM or dysplasia at baseline, and the small number of BE patients investigated. Recently, the efficiency of surveillance for BE patients has been discussed from the standpoint of cost-effectiveness. It may be too difficult to draw conclusions because no randomized clinical trials of BE surveillance have been performed.

Abstract
Objective To investigate the relationship between overweight and erosive esophagitis (EE) in a non-obese Taiwanese population. Design and Methods A total of 7,352 subjects (non-obese, 5,826; obese, 1,526) from a health examination center at National Cheng Kung University Hospital were enrolled. Central obesity was defined by a waist circumference (WC) ≥90 cm in male and 80 cm in female. Overweight was defined as body mass index (BMI) of 24–26.9 kg/m2, and general obesity as BMI ≥27 kg/m2. The Los Angeles classification was adopted to determine the presence of EE. Results There were significant differences in the prevalence of central obesity and different BMI status between subjects with and without EE in total and non-obese population. In total population, multivariate analyses revealed central obesity (OR, 1.17, 95% CI, 1.02–1.34, p = 0.021) and being obese (OR, 1.28, 95% CI, 1.07–1.52, p = 0.007)/overweight (OR, 1.25, 95% CI, 1.08–1.45, p = 0.003) had positive associations with EE in different model, respectively. When considering the joint effect of central obesity and BMI status, overweight (OR, 1.22; 95% CI, 1.04–1.44; p = 0.016) remained as an independent associated factor of EE but central obesity (OR, 1.06; 95% CI, 0.89–1.26; p = 0.549)/being obese (OR, 1.22; 95% CI, 0.98–1.53; p = 0.082) did not. As for non-obese group, separate model showed central obesity (OR, 1.19, 95% CI, 1.00–1.40, p = 0.046) and overweight (OR, 1.24; 95% CI, 1.07–1.44, p = 0.005) was positively associated with EE, respectively. However, being overweight (OR, 1.20; 95% CI, 1.02–1.42, p = 0.030) but not central obesity (OR, 1.08; 95% CI, 0.90–1.31; p = 0.398) was positively related to EE with considering the effect of overweight and central obesity simultaneously. Conclusion Overweight effect on EE was more detrimental than central obesity in non-obese subjects. In addition, male gender, hiatus hernia and alcohol use were also associated with increased risk of EE.

Miwa H, Hongo M, Kusano M. Combination of angiotensin II receptor blockers promotes proton pump inhibitor-based healing of reflux esophagitis. J Gastroenterol 2012; 47:249-55. [PMID: 22041918 DOI: 10.1007/s00535-011-0479-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2011] [Accepted: 08/27/2011] [Indexed: 02/04/2023]
Abstract
BACKGROUND Several studies have described factors associated with the failure of proton pump inhibitors (PPIs) to effect endoscopic healing of reflux esophagitis (RE), but few studies have addressed factors promoting PPI-based endoscopic healing. We performed post hoc analysis of a multicenter prospective cohort of RE patients to identify factors encouraging endoscopic healing of this disorder. METHODS Patients with RE received 10 or 20 mg rabeprazole for 8 weeks, and endoscopic findings before and after treatment were studied. To evaluate the effects of patient background factors on endoscopic healing, we performed multiple logistic regression analysis and determined the respective odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS A total of 454 patients who underwent endoscopy at baseline and again at week 8 were included in the analysis. After 8 weeks of treatment, improvement in endoscopic findings was observed in 94.1% (427/454) of patients, and endoscopic healing was seen in 76.7% (348/454). Multiple logistic regression analysis revealed that a combination of angiotensin II receptor blockers (ARBs) had a significant positive impact on endoscopic healing (OR 3.9, 95% CI 1.411-10.903), but no significant positive relationship was seen for other concomitant drugs such as nonsteroidal anti-inflammatory drugs and calcium channel blockers. Severe RE at baseline (OR 0.365, 95% CI 0.281-0.475) and PPI therapy prior to enrollment (OR 0.154, 95% CI 0.052-0.453) were found to have significant negative effects on endoscopic healing. CONCLUSIONS Concomitant use of ARBs may promote endoscopic healing of RE treated with PPIs.

Abstract
BACKGROUND Obesity has been associated with reflux esophagitis. However, the association of metabolic syndrome with reflux esophagitis remains unknown. METHODS A case-control study of 372 subjects undergoing upper endoscopy during health checkups was conducted (182 patients with reflux esophagitis vs 190 age and gender-matched controls). We further measured their height, weight, waist circumference, hip circumference, blood pressure, triglyceride, high-density lipoprotein, and fasting blood glucose. Multivariable linear regression analysis was used to identify the independent risk factors associated with the presence of reflux esophagitis. KEY RESULTS Reflux esophagitis cases showed higher mean waist circumference (81.37 ± 0.68 vs 79.36 ± 0.70, P < 0.05), waist hip ratio (0.86 ± 0.01 vs 0.84 ± 0.01, P < 0.05) and fasting blood glucose (5.59 ± 0.10 vs 5.32 ± 0.08, P < 0.05) than those in controls. When adjusted for gender and age, multivariate analysis demonstrated that there was a positive dose-response relationship between reflux esophagitis and waist hip ratio (men: OR 3.41, 95% CI 1.52-7.62, women: OR 3.37, 95% CI 1.61-7.06), triglyceride (OR 2.07, 95% CI 1.12-3.82), fasting blood glucose (OR 1.81, 95% CI 1.12-2.94), and metabolic syndrome (OR 2.01, 95% CI 1.15-3.50), there was an inverse dose-response relationship between reflux esophagitis and high-density lipoprotein for men (OR 0.36, 95% CI 0.15-0.85). CONCLUSIONS & INFERENCES High waist hip ratio, triglyceride, fasting blood glucose, and metabolic syndrome were associated with increased risk factors for reflux esophagitis while high high-density lipoprotein for men correlated with a reduced risk of reflux esophagitis.

Abstract
The prevalence of reflux esophagitis is increasing in Korea. To estimate the prevalence and clinical characteristics of reflux esophagitis in healthy subjects, we retrospectively examined the medical records of healthy subjects undergoing a routine check-up from October 2004 to September 2005. A total of 6,082 (3,590 men, mean age 44+/-10 yr) subjects were enrolled in this study. The prevalence of reflux esophagitis in healthy subjects was 10.5%. According to the univariate analysis, male sex (odds ratio [OR] 3.49, 95% confidence interval [CI] 2.84-4.30), smoking history (OR 1.91, 95% CI 1.60-2.28), body mass index (BMI) >30 kg/m(2) (OR 2.13, 95% CI 1.37-3.33), total cholesterol >250 mg/dL (OR 1.50, 95% CI 1.05-2.14), low-density lipoprotein (LDL) cholesterol >/=160 mg/dL (OR 1.52, 95% CI 1.08-2.14), triglyceride >/=150 mg/dL (OR 1.92, 95% CI 1.61-2.30), high blood pressure (BP) (OR 1.46, 95% CI 1.20-1.76), and fasting glucose >/=110 mg/dL (OR 1.45, 95% CI 1.13-1.86) were significantly associated with reflux esophagitis (all p<0.05). However, age, alcohol drinking and Helicobacter pylori infection were not associated with reflux esophagitis. In conclusion, significant relationships of reflux esophagitis with obesity, low high-density lipoprotein (HDL) cholesterol, high triglyceride, high BP, and elevated fasting glucose suggested that reflux esophagitis might represent the disease spectrum of the metabolic syndrome.

Abstract
BACKGROUND The prevalence of Barrett esophagus (BE) remains elusive in the general populations. GOALS The purpose of this study was to identify the prevalence and clinical characteristics of BE in a Chinese general population. STUDY Between June 2003 and December 2006, consecutive subjects were evaluated via upper gastrointestinal endoscopy during a routine health examination. Patients were evaluated for any abnormalities, including endoscopically suspected esophageal metaplasia (ESEM) and erosive esophagitis (EE). Biopsies were attained from patients with ESEM to confirm a diagnosis of BE. The demographic data and endoscopic findings were retrospectively analyzed. RESULTS Of the 19,812 endoscopies performed, 56 patients (0.28%) were diagnosed with ESEM and 3129 patients (15.7%) with EE. Twelve of the 56 patients diagnosed with ESEM (0.06% of the total number of patients who underwent endoscopy) were confirmed to have BE after histologic analysis of the biopsies. Patients with BE were older than patients without BE (61.6 vs. 51.7 y), and only one of the 12 patients diagnosed with BE (8.3%) reported typical gastroesophageal reflux symptoms. A majority of the BE patients were categorized as short-segment BE (91.7%) and concomitant EE was found in 4 (33.3%). Smoking, alcohol, and metabolic disorders seemed to be associated with the presence of BE and EE. CONCLUSIONS The prevalence of BE in a Chinese general population was lower than that in other reported studies, particularly in comparison with the studies originating from Western countries. Patients with advanced age and metabolic disorders are risk factors for developing BE.

Abstract
OBJECTIVES Esophageal adenocarcinoma and its precursor lesion, Barrett's esophagus, are increasing in incidence in western populations. Gastroesophageal reflux disease (GERD) and high body mass index (BMI) are known risk factors, but it is unclear whether BMI mediates its risk on Barrett's esophagus independently. This systematic review and meta-analysis investigated whether increasing BMI is associated with Barrett's esophagus as compared to general population and GERD controls. METHODS Search strategies were conducted in MEDLINE (U.S. National Library of Medicine, Bethesda, MD) (1966-2005) and EMBASE (Reed Elsevier PLC, Amsterdam, The Netherlands) (1980-2005). Studies to be included were required to present "current" BMI data for consecutively recruited Barrett's esophagus patients and appropriate comparison arms with a minimum number of 30 subjects in each. RESULTS The literature search produced 5,501 hits from which 295 papers were extracted. Only 10 studies met the criteria for inclusion. The Statistics/Data Analysis (STATA) program was used to conduct random effects meta-analyses. Nine studies comparing the BMI of the Barrett's esophagus and GERD groups produced a pooled odds ratio (OR) of 0.99 per kg/m2 (95% confidence interval [CI] 0.97-1.01, I2= 52%), while the pooled estimate of three studies comparing Barrett's esophagus with general population controls was 1.02 per kg/m2 (95% CI 1.01-1.04, I2= 0%). CONCLUSIONS Increasing adiposity is only an indirect risk factor of Barrett's esophagus through the precursor lesion of GERD. Hence, BMI status has no predictive value with respect to GERD patients and their risk of progression to Barrett's esophagus.

Abstract
BACKGROUND There are very few prospective follow-up studies of Barrett esophagus (BE) cohorts assessing the risk of extraesophageal cancer incidence or mortality. Such studies are necessary in order to understand the overall risks of cancer and death experienced by patients with BE. METHODS A cohort of 502 patients with BE were identified at Leeds General Infirmary, England. Mortality and cancer incidence information were provided by the Office for National Statistics. Standardized mortality ratios (SMR) and standardized incidence ratios (SIR) were calculated using indirect standardization. RESULTS All-cause mortality was found to be elevated in patients with BE [SMR, 1.21; 95% confidence interval (95% CI), 1.06, 1.37] and remained so after esophageal cancers were excluded (SMR, 1.16; 95% CI, 1.01-1.32). Increased mortality risks were also found for malignant neoplasms of the esophagus (SMR, 7.26; 95% CI, 3.87-12.42) and diseases of the digestive system (SMR, 2.03; 95% CI, 1.11-3.40). The remaining disease categories produced no altered risk estimates. Circulatory disease mortality was borderline statistically significant (SMR, 1.24; 95% CI, 1.00-1.52; P = 0.053) for those with a specialized intestinal metaplasia diagnosis of BE. In the cancer incidence analyses, esophageal malignancies (SIR, 8.66; 95% CI, 4.73-14.53) and esophageal adenocarcinomas (SIR, 14.29; 95% CI, 7.13-22.56) were found to be increased in BE. All remaining analyses provided unaltered risks, including that of colorectal cancer. CONCLUSIONS This study has shown evidence of an increased risk of esophageal cancer incidence and mortality in BE. It has also shown that those who have a histologic BE diagnosis may also have an increased risk of circulatory disease mortality.
