Association Between Anxiety/Depression and Gastroesophageal Reflux: A Systematic Review and Meta-Analysis

INTRODUCTION

An association between gastroesophageal reflux disease (GERD) and common psychiatric conditions, most notably anxiety and depression, has been reported. However, the magnitude of this association is poorly understood. Therefore, we aimed to systematically assess this issue.

METHODS

We comprehensively searched multiple bibliographic databases (Embase, PubMed, Scopus, and Web of Science) from inception to May 15, 2023. We retrieved observational studies that reported the prevalence of anxiety and/or depressive symptoms diagnosed by validated questionnaires in ≥100 adults (aged 18 years or older) with GERD. We also included cohort studies that explored the risk of incident GERD in subjects with anxiety/depression vice versa scenario. Finally, we included Mendelian randomization studies that assessed the cause-and-effect relationship between anxiety/depression and GERD. The extracted data were combined using a random-effects model.

RESULTS

In total, 36 eligible studies were included. The pooled prevalences of anxiety and depressive symptoms were 34.4% (95% confidence interval [CI] 24.7-44.2; I2 = 99.4%) and 24.2% (95% CI 19.9-28.5; I2 = 98.8%) in subjects with GERD based on 30 studies, respectively. Both anxiety and depressive symptoms were more common in subjects with GERD compared with those in healthy controls (odds ratio = 4.46 [95% CI 1.94-10.25] and odds ratio = 2.56 [95% CI 1.11-5.87], respectively). According to 3 cohort studies, subjects with GERD were at an increased risk of developing anxiety/depression and vice versa. Finally, 3 Mendelian randomization studies showed that genetic liability to these mood disorders is linked to an increased risk of developing GERD and vice versa.

DISCUSSION

Up to 1 in 3 subjects with GERD experience anxiety and depression. There is likely a bidirectional causal relationship between anxiety/depression and GERD.

Gender differences in symptoms in partial responders to proton pump inhibitors for gastro-oesophageal reflux disease

BACKGROUND

Gender differences may exist in the symptom experience of patients with gastro-oesophageal reflux disease (GERD) who have a partial response to proton pump inhibitors (PPIs).

OBJECTIVE

The purpose of this study was to analyse gender differences in partial responders to PPIs.

METHODS

Patients with GERD who responded partially to PPIs (n = 580; NCT00703534) completed the Reflux Symptom Questionnaire 7-day recall (RESQ-7) and the Gastrointestinal Symptom Rating Scale (GSRS). Anxiety and depression were evaluated using the Hospital Anxiety and Depression Scale.

RESULTS

Women had significantly higher RESQ-7 domain scores than men for Heartburn (frequency: 4.3 vs 3.9; intensity: 3.1 vs 2.8), Burping (frequency: 4.9 vs 4.4; intensity: 3.1 vs 2.8) and Hoarseness, cough and difficulty swallowing (frequency: 2.6 vs 2.2; intensity: 1.8 vs 1.5), and had higher GSRS domain discomfort scores than men for Abdominal pain (3.51 vs 3.23), Indigestion (3.80 vs 3.45) and Constipation (2.69 vs 2.17) (all p < 0.05). Anxiety and depression were significantly more prevalent in women than in men.

CONCLUSION

In this population of partial responders, women had more frequent/intense heartburn and extra-oesophageal symptoms and more discomfort from abdominal pain, indigestion and constipation than men. Comorbid anxiety and depression may contribute to the increased symptom burden in women.

[Use of health resources and loss of productivity in gastroesophageal reflux disease: results of a cross-sectional study in a primary care setting in Spain]

OBJECTIVE

To evaluate healthcare resource use and productivity in patients with gastro-esophageal reflux disease (GERD) and the influence of disease severity on these two factors.

DESIGN

Sub-analysis of the Spanish population of a multinational study with a 4-month retrospective period for the identification and selection of patients, and a clinical visit to obtain clinical information and data on use of healthcare resources, carried out between October 2007 and January 2008.

POPULATION

A total of 477 patients attending a Primary Care centre, with a medical consultation for GERD.

MAIN VARIABLES

Use of healthcare resources, changes in productivity based on the Work Productivity and Activity Impairment Questionnaire for GERD patients (WPAI-GERD).

RESULTS

Despite having received pharmacological treatment at the baseline visit, after a median of 5.1 months follow-up (range 2.1-8.1), up to 15.9% (95% CI; 12.8-19.5) patients still showed clinically relevant GERD symptoms. Direct medical costs per year associated with diagnostic tests and medical consultations in patients with or without clinically relevant GERD symptoms were 666 € (SD: 2,097 €) and 370 € (SD: 2,060 €), respectively. The mean annual cost of reduced productivity (17%) was 5,316 € (SD: 8,615 €). This cost was 4 times higher for patients with clinically relevant GERD symptoms than for patients with no relevant symptoms (15,188 € [SD: 11,206 €] vs 3,926 € [SD: 7,232 €]).

CONCLUSION

Patients with GERD use significant healthcare resources, attributable to associated medical costs and marked reduction in productivity, even though they receive pharmacological treatment.

[Study of the clinical profile and management of patients with gastroesophageal reflux disease in primary care in Spain]

OBJECTIVE

To assess the clinical profile and management of patients with gastroesophageal reflux disease (GERD) in primary care.

METHODS

A multinational, multicenter study was performed comprising a 4-month retrospective phase for the screening, selection and assessment of patients who had consulted for any GERD-related cause (index visit), and a cross-sectional phase in which clinical data were recorded and the following questionnaires were administered: the Reflux Disease Questionnaire and the Gastroesophageal Reflux Disease Impact Scale (GIS).

RESULTS

Among the 24 participating Spanish centers, 2.7% of the patients (95% CI: 2.6-2.9) had consulted at least once because of GERD. Approximately 50% of the patients showed frequent (2 or more days a week) or moderate to severe symptoms of heartburn, acid regurgitation or chest pain. Although the patients received effective pharmacological treatment at the index visit, clinically relevant GERD symptoms persisted in 16% after a median follow-up of 5 months. These symptoms were associated with a strong disease impact as evaluated with the GIS.

CONCLUSION

GERD represents a substantial burden for primary care physicians. Although effective drugs are used for the treatment of this condition, clinically relevant symptoms persist in a substantial proportion of patients.

Management of gastroesophageal reflux disease in primary care settings in Spain: SYMPATHY I study

OBJECTIVE

Our study was designed to assess the symptom loads, treatment strategies, and impact on daily life of patients with gastroesophageal reflux disease (GERD) symptoms who consulted primary care (PC) health care providers in Spain.

METHODS

This was a multicenter, observational, cross-sectional study in a sample of 5735 consecutive patients visiting PC clinics with GERD symptoms. Participating primary care physicians (PCPs) collected clinical data by using a questionnaire, and completed a survey on their perceptions of diagnostic and therapeutic approaches to GERD. Patients self-completed the GERD Impact Scale during the study visit.

RESULTS

In the week before visiting the PC clinic, typical GERD symptoms were present in a majority of patients (89.6% heartburn and 81.6% regurgitation), but extraesophageal symptoms were also frequent (55.6% reflux-related sleep disturbances, 45.7% noncardiac chest pain, 30.8% chronic cough, and 24.7% hoarseness), these being more prevalent in the patients diagnosed earlier. Although primary care physicians considered that 55.9% of the patients could be diagnosed on the basis of symptoms without further investigation, in their practice only one-third of new diagnoses of GERD and 71.1% of those already diagnosed were symptom-managed. Upon arrival at the clinic, patients with GERD symptoms were taking the following medications: 28.1% (47.8% in the case of those already diagnosed) proton pump inhibitors (PPIs), 16.6% antacids, 6.1% H2 antagonists, and 4.5% prokinetics. Most patients (90.2%) were treated with PPIs after the study visit. The evaluation of agreement between physicians and patients on the severity of GERD resulted in a kappa index of 0.19.

CONCLUSION

There is a high occurrence of typical and extraesophageal symptoms in patients in Spain complaining of GERD symptoms in PC settings. Two-thirds of new GERD patients were referred for further investigation. PPIs were the treatment prescribed in almost all cases. The degree of agreement between physicians and patients about the severity of the symptoms was limited.

Impact of gastroesophageal reflux disease on the quality of life of Spanish patients: the relevance of the biometric factors and the severity of symptoms

BACKGROUND

Gastroesophageal reflux disease (GERD) has a negative impact on health-related quality of life (HRQoL).

AIM

(i) To evaluate HRQoL in the general Spanish population with GERD. (ii) To analyze the influence of biometric factors and symptoms profile on HRQoL.

MATERIALS AND METHODS

A multicenter and population-based evaluation was performed. Surveys were sent out to the general population and 335 responders (16%) fulfilled symptomatic criteria of GERD. They filled out two HRQoL questionnaires [Short Form-36 (SF-36) and Quality of Life in Reflux and Dyspepsia]. Biometric factors and symptoms profile were collected. The SF-36 physical and mental component summary scores were calculated.

RESULTS

Two hundred and fifty-two individuals (75.2%) participated. SF-36 and Quality of Life in Reflux and Dyspepsia (QoLRAD) punctuations were lower compared with the general population. Female sex, severity of symptoms, and nocturnal symptoms were associated with a greater deterioration of HRQoL. Obese participants had a negative impact on the physical component summary score, but mental component summary score was better than in participants with normal weight. Adjusted by age, punctuations of smokers, exsmokers, and nonsmokers were similar. No differences in HRQoL with regard to alcohol consumption were observed.

CONCLUSION

In participants who fulfill symptomatic criteria of GERD, the HRQoL is very deteriorated. The factors that worsen the QoL are being female, increase in BMI, and nocturnal symptoms.

[Validation of the Reflux Disease Questionnaire (RDQ) and Gastrointestinal Impact Scale (GIS) in patients with gastroesophageal reflux disease in the Spanish population]

OBJECTIVES

To assess the feasibility, reliability, validity and sensitivity of changes in the Reflux Disease Questionnaire (RDQ) and the Gastrointestinal Impact Scale (GIS).

MATERIAL AND METHODS

An observational, prospective, multicenter study was conducted in primary care centers on two visits (baseline and 16 days later) in a sample of patients with a diagnosis of gastroesophageal reflux disease (GERD) or suspicion of GERD requiring a therapeutic intervention (sensitivity to change group, n=230) and in another sample of patients with clinically controlled GERD (reliability group, n=51).

RESULTS

The RDQ questionnaire and GIS scale, both overall and for each domain, showed a Cronbach's alpha of greater than or equal to 0.70. All RDQ domains and the total score, as well as the total GIS score and impact dimension, showed a high correlation between the baseline evaluation and that performed 16 days later in stable patients. The RDQ and GIS showed very high correlations between the total scores and those of the quality of life in reflux and dyspepsia (QOLRAD) (-0.73 and 0.80, respectively), a reflux- and dyspepsia-specific quality of life scale, and a high correlation with the gastrointestinal symptoms rating scale (GSRS) (0.54 and -0.55, respectively), a general scale of gastrointestinal symptoms. Both the RDQ questionnaire and the GIS scale showed significant changes with a high effect size on improvement responses.

CONCLUSIONS

The RDQ and GIS questionnaires show very good psychometric properties, making them suitable for use in primary care.

An international comparison of the burden of illness in patients with dyspepsia

BACKGROUND/AIMS

This study investigates the symptoms and the impact of symptoms on health-related quality of life (HRQL) in patients consulting with dyspepsia.

METHODS

Consecutive patients with a diagnosis of dyspepsia were recruited from primary and secondary care in Germany, Hungary, Italy, Poland, South Africa and Spain. Investigators assessed symptom frequency and severity, and subjects completed the following questionnaires: the Gastrointestinal Symptom Rating Scale (GSRS), the Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaire, the Hospital Anxiety and Depression (HAD) scale and the Short Form 36 (SF-36).

RESULTS

853 dyspepsia patients were included. Mean GSRS scores showed that patients were most troubled by abdominal pain and indigestion. QOLRAD scores indicated that symptoms caused emotional distress, food/drink problems and reduced vitality, with a lesser effect on sleep and physical functioning. Mean SF-36 scores were lower than mean normative values for all domains, indicating that patients had a worse HRQL than the normal population, particularly for Bodily Pain, Role Physical and Role Emotional. Of patients in each country, 18-43% were anxious and 11-21% were depressed.

CONCLUSIONS

Patients with dyspepsia have reduced HRQL because their symptoms - particularly abdominal pain and indigestion - cause emotional distress, problems with food and drink, and impaired vitality.

[Quality of life after laparoscopic fundoplication for gastroesophageal reflux disease]

OBJECTIVE

To evaluate our results in terms of satisfaction and quality of life in patients who underwent laparoscopic 360 degrees fundoplication for gastroesophageal reflux disease.

PATIENTS AND METHOD

We performed a cross-sectional study of 49 consecutive patients who underwent laparoscopic 360 degrees fundoplication for gastroesophageal reflux disease. All patients had been operated on more than 6 months previously by the same surgeon. Postoperative morbidity was recorded. Patients were sent the SF-36 and GIQLI quality of life questionnaires and were also asked about their degree of satisfaction with the surgery.

RESULTS

The mean age was 40.5 years (range, 23-71). There were nine women and 40 men. All patients underwent a floppy 360 degrees fundoplication and crural closure. There were no conversions. The complication rate was 8.2% (one case each of fever of unknown origin, acute urinary retention, self-limiting bleeding and hernia from a port). Forty-three patients completed the questionnaires (87.7%). Satisfaction with surgery was 8.7 points (out of 10), 89.5% would undergo surgery again and 94.6% would recommend it to a relative. The results of the SF-36 questionnaire were similar to population-based reference values except in the domains of physical functioning and bodily pain where statistically significant differences were found. The mean global GIQLI score was 110.8, which was similar to other studies published in the medical literature.

CONCLUSIONS

Although this is a cross-sectional study, these preliminary results indicate a high degree of satisfaction with laparoscopic fundoplication, which was reflected in the results of the quality of life questionnaires.
