Impact of body mass index and gender on quality of life in patients with gastroesophageal reflux disease

RETRACTED: A Phase III Head-to-Head Study to Compare the Efficacy and Safety of Fexuprazan and Esomeprazole in Treating Patients with Erosive Esophagitis

Background: Fexuprazan (Fexuclue®; Daewoong Pharmaceutical Co., Ltd., Seoul, Korea) is a novel potassium-competitive acid blocker (P-CAB). This multi-center, randomized, double-blind, active-controlled, parallel-group, therapeutic confirmatory, phase III study was conducted to assess its efficacy and safety compared with esomeprazole (Nexium®; AstraZeneca, Gothenburg, Mölndal, Sweden) in Korean patients with erosive esophagitis (EE). Methods: This study evaluated patients diagnosed with EE at a total of 25 institutions in Korea between 13 December 2018 and 7 August 2019. After voluntarily submitting a written informed consent form, the patients were evaluated using a screening test and then randomized to either of the two treatment arms. The proportion of the patients who achieved the complete recovery of mucosal breaks at 4 and 8 weeks, the proportion of those who achieved the complete recovery of heartburn at 3 and 7 days and 8 weeks, and changes in the GERD-Health-Related Quality of Life Questionnaire (GERD-HRQL) scores at 4 and 8 weeks from baseline served as efficacy outcome measures. The incidence of treatment-emergent adverse events (TEAEs) and adverse drug reactions (ADRs) and the serum gastrin levels served as safety outcome measures. Results: The study population comprised a total of 231 patients (n = 231) with EE, including 152 men (65.80%) and 79 women (34.20%); their mean age was 54.37 ± 12.66 years old. There were no significant differences in the efficacy and safety outcome measures between the two treatment arms (p > 0.05). Conclusions: It can be concluded that the efficacy and safety of Fexuclue® are not inferior to those of esomeprazole in Korean patients with EE.

Risk factors and 26-years worldwide prevalence of endoscopic erosive esophagitis from 1997 to 2022: a meta-analysis

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.

Gastroesophageal Reflux Disease in Idiopathic Pulmonary Fibrosis: Viewer or Actor? To Treat or Not to Treat?

Background: Idiopathic pulmonary fibrosis (IPF) is a rare and severe disease with a median survival of ∼3 years. Several risk factors have been identified, such as age, genetic predisposition, tobacco exposure, and gastro-oesophageal reflux disease (GERD). Prevalence of GERD in IPF is high and may affect 87% of patients, of whom only half (47%) report symptoms. Objective: The aim of this study is to review current evidence regarding the correlation between GERD and IPF and to evaluate the current studies regarding treatments for GERD-IPF. Methods: A review to identify research papers documenting an association between GERD and IPF was performed. Results: We identified several studies that have confirmed the association between GERD and IPF, with an increased acid exposure, risk of gastric aspiration and bile acids levels in these patients. Few studies focused their attention on GERD treatment, showing how antiacid therapy was not able to change IPF evolution. Conclusions: This review investigating the correlation between GERD and IPF has confirmed the hypothesized association. However, further large prospective studies are needed to corroborate and elucidate these findings with a focus on preventative and treatment strategies.

Independent factors associated with the impact of gastroesophageal reflux disease on health-related quality of life

BACKGROUND

although a number of factors have been associated with a deterioration in quality of life in gastroesophageal reflux disease, it is not known which has an independent influence.

OBJECTIVE

to evaluate factors independently associated with the impact of gastroesophageal reflux disease on health-related quality of life.

METHODS

a post-hoc analysis of a prospective cohort of patients diagnosed with gastroesophageal reflux disease was performed. The patients completed validated questionnaires to evaluate health-related quality of life (SF 36), gastroesophageal reflux disease (GERQ) and psychological factors (STAI and SCL 90R).

RESULTS

the study included 98 patients. The univariate analysis showed that a deterioration in the physical component of the SF36 was significantly associated with female gender, educational level, age, weight loss, severity of typical symptoms, supraesophageal symptoms and monthly income. The mental component was significantly associated with alcohol consumption, epigastric pain and lower scores on the STAI and SCL90 questionnaires. The multivariate analysis showed an independent association between the physical component of the SF36 and educational level (β = 0.29; p < 0.01), severity of symptoms (β = -0.38; p < 0.001), body mass index (β = -0.30; p < 0.005), state anxiety (β = 0.28; p < 0.01), female gender (β = -0.23; p < 0.05) and dyspepsia (β = -0.21; p < 0.05). Associated variables within the mental component included state anxiety (β = -0.39; p < 0.01) and depression (β = -0.32; p < 0.05).

CONCLUSIONS

the principal factors independently associated with a deterioration in health-related quality of life in patients with gastroesophageal reflux disease included the severity of typical symptoms and the presence of dyspepsia. There is also an additional impact of body mass index and the psychological component.

Impact of Obesity on a Chinese Population with Erosive Esophagitis and Barrett's Esophagus

Background/Aims

The aim of this study was to investigate the associations between obesity and erosive esophagitis (EE) or Barrett's esophagus (BE) in a Chinese population.

Methods

Data from subjects were retrospectively collected from 2006 to 2009. Individuals with BE were identified and age- and sex-matched at a 1:2 ratio with normal esophagocardial junction and EE patients. The subjects were stratified into two groups: the normal weight group and overweight/ obesity group (body mass index ≥25 mg/m²) or the normal waist group and abdominal obesity group (waist circumference ≥90 cm for men and ≥80 cm for women).

Results

Overall, 45%, 72%, and 52% were overweight/obese and 23%, 65%, and 18% had abdominal obesity in the normal, EE, and BE groups, respectively. Positive associations were identified between EE and overweight/obesity (odds ratio [OR], 3.14; 95% confidence interval [CI], 1.75 to 5.66) and abdominal obesity (OR, 6.22; 95% CI, 3.34 to 11.57); however, the associations were nonsignificant between BE and overweight/obesity (OR, 1.32; 95% CI, 0.67 to 2.61) or abdominal obesity (OR, 0.73; 95% CI, 0.31 to 1.73). Female BE patients had a significantly increased rate of being overweight/obese.

Conclusions

Obesity is a contributing factor in EE. The association of BE and obesity was not significant, with the exception of female BE cases.

Correlation Between Symptom Severity and Health-Related Life Quality of a Population With Gastroesophageal Reflux Disease

BACKGROUND

Gastroesophageal reflux disease (GERD) is a chronic disease with a negative impact on the quality of life. The aim of this study was to investigate the reflux symptoms and the health-related quality of life in a population with GERD.

METHODS

Data from patients with GERD, according to the Montreal definition, were collected between January and December 2009. The enrolled patients were classified by different reflux symptoms according to the modified Chinese GERDQ. The general demographic data, the modified GERD impact scores and the SF-36 questionnaire scores of these groups of patients were analyzed.

RESULTS

A total of 173 patients were enrolled, and the general data, endoscopic findings and lifestyle habits of the participants with different severity of heartburn or regurgitation were all similar. The patients with moderate severity of reflux symptoms had significant lower SF-36 scores than those with mild severity. The cases with advanced heartburn severity owned the lowest scores among all cases. The impact on the daily activity of each affected individual had a positive association with the stronger severity of reflux symptom.

CONCLUSION

The life quality of a population with GERD achieved the meaningful declination in participants with the moderate severity of heartburn or regurgitation. The severity of the reflux symptoms had a greater impact on the normal daily activity of the patients with GERD. The cases with advanced severity of heartburn had the worst well-being.

Zero-Inflated Models for Identifying Relationships Between Body Mass Index and Gastroesophageal Reflux Symptoms: A Nationwide Population-Based Study in China

BACKGROUND AND AIM

That obesity leads to gastroesophageal reflux is a widespread notion. However, scientific evidence for this association is limited, with no rigorous epidemiological approach conducted to address this question. This study examined the relationship between body mass index (BMI) and gastroesophageal reflux symptoms in a large population-representative sample from China.

METHODS

We performed a cross-sectional study in an age- and gender-stratified random sample of the population of five central regions in China. Participants aged 18-80 years completed a general information questionnaire and a Chinese version of the Reflux Disease Questionnaire. The zero-inflated Poisson regression model estimated the relationship between body mass index and gastroesophageal reflux symptoms.

RESULTS

Overall, 16,091 (89.4 %) of the 18,000 eligible participants responded. 638 (3.97 %) and 1738 (10.81 %) experienced at least weekly heartburn and weekly acid regurgitation, respectively. After adjusting for potential risk factors in the zero-inflated part, the frequency [odds ratio (OR) 0.66, 95 % confidence interval (95 % CI) 0.50-0.86, p = 0.002] and severity (OR 0.66, 95 % CI 0.50-088, p = 0.004) of heartburn in obese participants were statistically significant compared to those in normal participants. In the Poisson part, the frequency of acid regurgitation, overweight (OR 1.10, 95 % CI 1.01-1.21, p = 0.038) and obesity (OR 1.19, 95 % CI 1.04-1.37, p = 0.013) were statistically significant. BMI was strongly and positively related to the frequency and severity of gastroesophageal reflux symptoms. Additionally, gender exerted strong specific effects on the relationship between BMI and gastroesophageal reflux symptoms.

CONCLUSIONS

The severity and frequency of heartburn were positively correlated with obesity. This relationship was presented distinct in male participants only.

Hiatal hernia on thoracic computed tomography in pulmonary fibrosis

Gastro-oesophageal reflux has long been suspected of implication in the genesis and progression of idiopathic pulmonary fibrosis (IPF). We hypothesised that hiatal hernia may be more frequent in IPF than in other interstitial lung disease (ILD), and that hiatal hernia may be associated with more severe clinical characteristics in IPF.We retrospectively compared the prevalence of hiatal hernia on computed tomographic (CT) scans in 79 patients with IPF and 103 patients with other ILD (17 scleroderma, 54 other connective tissue diseases and 32 chronic hypersensitivity pneumonitis). In the IPF group, we compared the clinical, biological, functional, CT scan characteristics and mortality of patients with hiatal hernia (n=42) and without hiatal hernia (n=37).The prevalence of hiatal hernia on CT scan at IPF diagnosis was 53%, similar to ILD associated with scleroderma, but significantly higher than in the two other ILD groups. The size of the hiatal hernia was not linked to either fibrosis CT scan scores, or reduction in lung function in any group. Mortality from respiratory causes was significantly higher among IPF patients with hiatal hernia than among those without hiatal hernia (p=0.009).Hiatal hernia might have a specific role in IPF genesis, possibly due to pathological gastro-oesophageal reflux.

Difference in efficacy of proton pump inhibitor between new-onset and recurrent gastroesophageal reflux disease: Result from a study of on-demand versus continuous maintenance therapy in Japan

BACKGROUND-OBJECTIVE

No study has focused on the difference in efficacy of maintenance therapy between patients with new-onset and recurrent gastroesophageal reflux disease (GERD). The aim of this study is to reveal this point.

METHODS

Endoscopically proven GERD patients who had completed 8-week initial therapy were sequentially randomized to continuous arm (Omeprazole 20mg od) or on-demand arm (Omeprazole 20mg on-demand). Patients filled in daily symptoms and tablet usages for 24 weeks. Patients underwent upper GI endoscopy at 24 weeks. Symptom relief was defined as no symptoms for>6 days during a week. The numbers of patients who achieved symptom relief and mucosal healing were compared between the new-onset and recurrent groups in the continuous arm and in the on-demand arm, respectively.

RESULTS

Among new-onset GERD [n=82 (continuous: 42 patients, on-demand: 40)], continuous arm achieved significant symptom-relief than in on-demand arm at 4*,5*,6** and 17*week. Among recurrent GERD [n=36(continuous: 17 patients, on-demand: 19)], continuous arm achieved significant symptom-relief at 1**,2*,3*,4*,5**,7**,8**,17* and 18* week, respectively (*<0.05,**<0.01). The number of healed patients was significantly higher in new-onset group (60/68, 88.2%) than in recurrent group (17/30, 56.7%) (<0.01).

CONCLUSION

Since therapeutic response during maintenance therapy was poor in recurrent GERD, continuous therapy is recommended in order to maintain symptom-relief and mucosal healing. Hippokratia 2015, 19 (1): 53-56.

Heartburn and regurgitation have different impacts on life quality of patients with gastroesophageal reflux disease

AIM: To investigate the impact of heartburn and regurgitation on the quality of life among patients with gastroesophageal reflux disease (GERD).

METHODS: Data from patients with GERD, who were diagnosed according to the Montreal definition, were collected between January 2009 and July 2010. The enrolled patients were assigned to a heartburn or a regurgitation group, and further assigned to an erosive esophagitis (EE) or a non-erosive reflux disease (NERD) subgroup, depending on the predominant symptoms and endoscopic findings, respectively. The general demographic data, the scores of the modified Chinese version of the GERDQ and the Short-form 36 (SF-36) questionnaire scores of these groups of patients were compared.

RESULTS: About 108 patients were classified in the heartburn group and 124 in the regurgitation group. The basic characteristics of the two groups were similar, except for male predominance in the regurgitation group. Patients in the heartburn group had more sleep interruptions (22.3% daily vs 4.8% daily, P = 0.021), more eating or drinking problems (27.8% daily vs 9.7% daily, P = 0.008), more work interferences (11.2% daily vs none, P = 0.011), and lower SF-36 scores (57.68 vs 64.69, P = 0.042), than patients in the regurgitation group did. Individuals with NERD in the regurgitation group had more impaired daily activities than those with EE did.

CONCLUSION: GERD patients with heartburn or regurgitation predominant had similar demographics, but those with heartburn predominant had more severely impaired daily activities and lower general health scores. The NERD cases had more severely impaired daily activity and lower scores than the EE ones did.

Associação entre impactos funcionais e psicossociais das desordens bucais e qualidade de vida entre idosos

Objetivou-se avaliar a associação entre o impacto das desordens bucais em suas dimensões física/psicossocial e a qualidade de vida entre idosos. Estudo transversal conduzido entre idosos (65-74 anos), em 2008/2009. O impacto foi avaliado através do Oral Health Impact Profile (OHIP 14) e a qualidade de vida, através do Short-Form Health Survey SF 12. Foram realizadas análises descritivas, univariadas e múltiplas (regressões logísticas), com correção pelo efeito de desenho, utilizando-se o PASW(r) 18.0. Dos 800 convidados, participaram 736 idosos (TR = 92%), com a média de idade de 67,77 anos, a maioria não apresentou impacto, a partir da medida da prevalência do OHIP. A dimensão limitação funcional do OHIP foi associada ao domínio físico do SF12, independentemente de outras variáveis investigadas. Já a gravidade do OHIP, as suas dimensões de desconforto psicológico e deficiência, foram associadas ao domínio mental do SF12. Conclui-se que alguns impactos das desordens bucais estiveram associados a uma qualidade de vida insatisfatória em seus domínios físico e mental.

Scintigraphic methods to evaluate alterations of gastric and esophageal functions in female obesity

OBJECTIVE

Altered gastrointestinal function has frequently been observed in obese patients. The aim of this study was to investigate the frequency of gastro-esophageal reflux (GER) and to determine the alterations of gastric emptying and esophageal transit by scintigraphic methods in obese patients.

METHODS

Scintigraphic studies of 50 obese female non-diabetic patients who had not received any treatment for weight control were retrospectively reviewed. Mean Body Mass Index (BMI) was 34.96±3.04 kg/m(2) (range:32-39 kg/m(2)). All subjects were submitted to scintigraphic evaluation of esophageal transit, gastro-esophageal reflux, gastric emptying and presence of Helicobacter pylori infection. The data of obese patients were compared with those of sex-age matched 30 non-obese cases who were selected from our clinical archive.

RESULTS

In obese group, seventeen (34%) patients were found to be GER positive scintigraphically; mean gastric emptying time (t½) was 59.18±30.8 min and the mean esophageal transit time was 8.9±7.2 s. Frequency of positive GER scintigraphy and the mean value of esophageal transit time were significantly higher in obese patients than non-obese control subjects. Gastric emptying time and esophageal transit time values were significantly longer in GER positive obese patients than GER negative ones. There was no statistically significant difference in the frequency of positive C14 urea breath test between obese and non-obese subjects and there were also no statistically significant correlations between BMI, GER, esophageal transit time and gastric emptying time.

CONCLUSION

In our study, 42 of the 50 obese patients had esophago-gastric motility alterations. The significance of these alterations in obesity is not fully understood, but it is believed that these changes could be because of potential contributing factors in the development or maintenance of obesity or changes in eating habits.

Characteristics of symptom presentation and risk factors in patients with erosive esophagitis and nonerosive reflux disease

OBJECTIVE

The aim of this study was to investigate the effect of gender on symptom presentation and quality of life of patients with erosive esophagitis (EE) and nonerosive reflux disorder (NERD).

SUBJECTS AND METHODS

Medical records from patients with gastroesophageal reflux disease (GERD) between January and December 2009 were reviewed. The patients were assigned to either the EE or the NERD group. The general demographic data, the modified Chinese GERDQ scores and the Short Form (SF)-36 life quality questionnaire scores of the two groups of patients were compared.

RESULTS

Of the 261 patients, 87 (33.3%), 86 (33.0%) and 88 (33.7%) patients were classified into the EE, the NERD and the control groups, respectively. The patients in the EE group were significantly older (48.94 ± 17.38 vs. 43.34 ± 12.67 years), were predominately male (58.6 vs. 39.5%), had more frequently hiatal hernia (34.5 vs 17.4%), had a higher body weight (67.57 ± 15.13 vs. 61.06 ± 11.08 kg) and a higher body mass index (24.09 ± 4.61 vs. 22.68 ± 3.12) than those in the NERD group. The GERD-specific symptom scores and the general life quality scores of the EE and the NERD groups were similar, and both groups had lower life quality scores than the control group did. The female patients with NERD had a higher frequency of GERD symptoms and lower quality of life scores. Gender had no effect on symptom scores or life quality scores in the EE group.

CONCLUSION

The GERD-specific symptom severity and general quality of life scores of the EE and the NERD patients were similar. Gender had a great influence on symptom presentation and quality of life in patients with NERD, but not in those with EE.

The risk factors and quality of life in patients with overlapping functional dyspepsia or peptic ulcer disease with gastroesophageal reflux disease

Background/Aims

Gastroesophageal reflux disease (GERD), functional dyspepsia (FD), and peptic ulcer disease (PUD) impact the daily lives of affected individuals. The aim of this study was to compare the risk factors and impacts on life quality of overlapping FD or PUD in patients with GERD.

Methods

Data from patients diagnosed with GERD were collected between January and November 2009. FD was defined using the Rome III diagnostic criteria. The overlapping GERD-FD or GERD-PUD groups were classified as concomitant GERD and FD or peptic ulcers. The characteristics of these individuals were analyzed.

Results

There were 63, 48, and 60 patients in the GERD only, overlapping GERD-FD, and overlapping GERD-PUD groups, respectively. Significantly younger age, female gender, lower body weight and body mass index, and higher rates of tea consumption were noted in the GERD-FD group. Patients in the GERD-FD group exhibited the lowest quality of life scores, both with respect to physical and mental health, on the Short Form 36 domains.

Conclusions

Patients with concomitant GERD and FD were more likely to be younger and female. Overlapping GERD and FD had the worst impact on the quality of life of the affected individuals.

Incidence of gastroesophageal reflux disease in Uygur and Han Chinese adults in Urumqi

AIM: To investigate the incidence of gastroesophageal reflux disease (GERD) and its related risk factors in Uygur and Han Chinese adult in Urumqi, China.

METHODS: A population-based cross-sectional survey was undertaken in a total of 972 Uygur (684 male and 288 female) aged from 24 to 61 and 1023 Han Chinese (752 male and 271 female) aged from 23 to 63 years. All participants were recruited from the residents who visited hospital for health examination from November 2011 to May 2012. Each participant signed an informed consent and completed a GERD questionnaire (Gerd Q) and a lifestyle-food frequency questionnaire survey. Participants whose Gerd Q score was ≥ 8 and met one of the following requirements would be enrolled into this research: (1) being diagnosed with erosive esophagitis (EE) or Barrett’s esophagus (BE) by endoscopy; (2) negative manifestation under endoscopy (non-erosive reflux disease, NERD) with abnormal acid reflux revealed by 24-h esophageal pH monitoring; and (3) suffering from typical heartburn and regurgitation with positive result of proton pump inhibitor test.

RESULTS: According to Gerd Q scoring criteria, 340 cases of Uygur and 286 cases of Han Chinese were defined as GERD. GERD incidence in Uygur was significantly higher than in Han Chinese (35% vs 28%, χ² = 11.09, P < 0.005), Gerd Q score in Uygur was higher than in Han Chinese (7.85 ± 3.1 vs 7.15 ± 2.9, P < 0.005), and Gerd Q total score in Uygur male was higher than in female (8.15 ± 2.8 vs 6.85 ± 2.5, P < 0.005). According to normalized methods, 304 (31%) cases of Uygur were diagnosed with GERD, including 89 cases of EE, 185 cases of NERD and 30 cases of BE; 256 (25%) cases of Han Chinese were diagnosed with GERD, including 90 cases of EE, 140 cases of NERD and 26 cases of BE. GERD incidence in Uygur was significantly higher than in Han Chinese (31% vs 25%, χ² = 9.34, P < 0.005) while the incidences were higher in males of both groups than in females (26% vs 5% in Uygur, χ² = 35.95, P < 0.005, and 19.8% vs 5.2% in Han, χ² = 5.48, P < 0.025). GERD incidence in Uygur male was higher than in Han Chinese male (26% vs 19.8%, χ² = 16.51, P < 0.005), and incidence of NERD in Uygur was higher than in Han Chinese (χ² = 10.06, P < 0.005). Occupation (r = 0.623), gender (r = 0.839), smoking (r = 0.322), strong tea (r = 0.658), alcohol drinking (r = 0.696), meat-based diet (mainly meat) (r = 0.676) and body mass index (BMI) (r = 0.567) were linearly correlated with GERD in Uygur (r = 0.833, P = 0.000); while gender (r = 0.957), age (r = 0.016), occupation (r = 0.482), strong tea (r = 1.124), alcohol drinking (r = 0.558), meat diet (r = 0.591) and BMI (r = 0.246) were linearly correlated with GERD in Han Chinese (r = 0.786, P = 0.01). There was no significant difference between Gerd Q scoring and three normalized methods for the diagnosis of GERD.

CONCLUSION: GERD is highly prevalent in adult in Urumqi, especially in Uygur. Male, civil servant, smoking, strong tea, alcohol drinking, meat diet and BMI are risk factors correlated to GERD.
