A comparison between a gastroesophageal reflux disease questionnaire-based algorithm and multichannel intraluminal impedance-pH monitoring for the treatment of gastroesophageal reflux-induced chronic cough. Ther Adv Respir Dis 2024; 18:17534666231220817. [PMID: 38183243 PMCID: PMC10771753 DOI: 10.1177/17534666231220817] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Accepted: 11/29/2023] [Indexed: 01/07/2024] Open
Abstract
BACKGROUND Empiric therapy with multichannel intraluminal impedance-pH monitoring (MII-pH) has been used for the initial treatment of gastroesophageal reflux-induced chronic cough (GERC). However, an algorithm based on the gastroesophageal reflux disease questionnaire (GerdQ) has the potential to achieve a simple, structured, and effective treatment approach for patients with GERC. OBJECTIVES This study compared the efficacy of anti-reflux therapy based on GerdQ (new structured pathway, NSP) with medical treatment after MII-pH examination (ordinary clinical pathway, OCP) in the management of GERC. DESIGN For the NSP, we adapted the GerdQ score to establish the basis for a treatment algorithm. For the OCP, treatment was determined using the MII-pH examination results. METHODS The non-inferiority (NI) hypothesis was used to evaluate NSP versus OCP. RESULTS Overall, the NSP and OCP-based therapeutic algorithms have similar efficacy for GERC [NI analysis: 95% confidence interval (CI), -4.97 to 17.73, p = 0.009; superiority analysis: p = 0.420]. Moreover, the cough symptom scores and cough threshold improved faster in the NSP group than in the OCP group at week 8 (p < 0.05). In the subgroup analyses using the GerdQ and GerdQ impact scale (GIS) scores, patients with low-likelihood GERC (GerdQ < 8) were more likely to benefit from OCP (NI analysis: 95% CI, -19.73 to 18.02, p = 0.213). On the other hand, in patients with high-likelihood and low-reflux impact GERC patients (GerdQ > 8 and GIS < 4), the NSP arm was not inferior to the standard treatment of OCP (NI analysis: 95% CI, -8.85 to 28.21%, p = 0.04; superiority analysis: p = 0.339), indicating that GerdQ- and GIS-guided diagnosis and management of patients with GERC could be an alternative to MII-pH management, especially in settings with reduced medical resources. CONCLUSIONS The use of the GerdQ algorithm should be considered when handling patients with GERC in the primary care setting. TRIAL REGISTRATION This research was registered in the Chinese Clinical Trials Registry (ChiCTR-ODT-12001899).

Diagnostic accuracy of gastroesophageal reflux disease questionnaire for gastroesophageal reflux disease: A systematic review and meta-analysis. Neurogastroenterol Motil 2023; 35:e14619. [PMID: 37278156 DOI: 10.1111/nmo.14619] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 04/25/2023] [Accepted: 05/17/2023] [Indexed: 06/07/2023]
Abstract
BACKGROUND The use of a symptom-based gastroesophageal reflux disease (GERD) questionnaire (GerdQ) for GERD diagnosis has gained interest due to its greater efficacy and ease of use than other available questionnaires. However, different guidelines have given inconsistent recommendations regarding using GerdQ as a diagnostic test. This meta-analysis summarized the diagnostic accuracy of GerdQ for diagnosing GERD. METHODS Studies published up to April 12, 2023, and indexed in MEDLINE, EMBASE, SCOPUS, Web of Science, and the Cochrane Library were searched. Diagnostic test accuracy studies comparing GerdQ with upper endoscopy and/or pH-metry for GERD diagnosis in adult patients with symptoms suggestive of GERD were included. The study quality was assessed using the QUADAS-2 tool. Meta-analysis using bivariate (Reitsma) analysis was done to summarize the overall sensitivity, specificity, likelihood ratios (LRs), and diagnostic odds ratio (DOR). The summary receiver operating characteristics (SROC) curve was visualized, and the area under the ROC (AUC) was calculated. KEY RESULTS A total of 13 studies with 11,166 participants were included in the meta-analysis. The pooled sensitivity, specificity, positive LR, negative LR, and DOR for GerdQ (cut-off value of ≥8) were 66.9% (95% CI 56.4%-73.1%), 65.2% (95% CI 56.4%-73.1%), 1.93 (95% CI 1.55-2.42), 0.51 (95% CI 0.38-0.66), and 3.89 (95% CI 2.44-5.89), respectively. The overall AUC from the SROC was 0.705. The subgroup analysis showed similar pooled sensitivity, specificity, and DOR between Asian and non-Asian studies. CONCLUSIONS & INFERENCES GerdQ had moderate sensitivity and specificity for GERD diagnosis. GerdQ can still be recommended as a diagnostic tool for GERD, especially when the PPI test is unavailable or contraindicated.

BMC Gastroenterol 2023; 23:130. [PMID: 37076820 PMCID: PMC10116815 DOI: 10.1186/s12876-023-02758-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Accepted: 04/06/2023] [Indexed: 04/21/2023] Open
Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) symptom is a relapsing chronic medical condition resulting from the reflux of gastric acid contents into the esophagus and throat or mouth. It interferes with social functioning, sleep, productivity, and quality of life. Despite this, the magnitude of GERD symptoms is not known in Ethiopia. Therefore, this study was conducted to determine the prevalence and associated factors of GERD symptoms among university students in the Amhara national regional state. METHODS An institutional-based cross-sectional study was employed in Amhara national regional state Universities, from April 1, 2021, to May 1, 2021. Eight hundred and forty-six students were included in the study. A stratified multistage sampling technique was employed. Data were collected by using a pretested self-administered questionnaire. Data were entered via Epi Data version 4.6.0.5 and analyzed by SPSS version-26 software. The bivariable and multivariable binary logistic regression analyses were used to determine the associated factors of GERD symptoms. The adjusted odds ratio (AOR) with a 95% confidence interval (CI) was calculated. Variables having a p-value of ≤ 0.05 were considered statistically significant. RESULTS The prevalence of GERD symptoms in this study was 32.1% (95% CI = 28.7-35.5%). Being in the age of 20-25 years (AOR = 1.74, 95%CI = 1.03-2.94), female (AOR = 1.67, 95% CI = 1.15-2.41), use of antipain (AOR = 2.47, 95% CI = 1.65-3.69) and soft drinks (AOR = 1.58, 95% CI = 1.13-2.20) were significantly associated with higher odds of GERD symptoms. Urban dwellers had less chance of having GERD symptoms (AOR = 0.67, 95% CI = 0.48-0.94). CONCLUSION Nearly one-third of university students are affected by GERD symptoms. Age, sex, residence, use of antipain, and consumption of soft drinks were significantly associated with GERD. Reducing modifiable risk factors such as antipain use and soft drink consumption among students is advisable to decrease the disease burden.

Abstract
Purpose There is insufficient information about the prevalence and risk factors of gastroesophageal reflux disease (GERD) in the Chinese adult population. We aimed to assess the prevalence and identify the risk factors of GERD in China. Methods We collected data from a nationally representative sample (50,991 subjects) of Chinese adults from a large nation-wide cross-sectional survey. GERD was diagnosed by a standardized Chinese-language GERD questionnaire with a score of ≥ 8. The demographic characteristics, comorbidities and periodontal factors of all participants were collected. Results Fifty-thousands-one-hundred-eighty-three participants were finally included in this study. The overall prevalence of GERD was 5.6% (95% CI, 5.4-5.8%) among the general Chinese population aged 20 years or older. Women, smokers, and people with older age, BMI ≥ 25.0 kg/m2, urban residence, lower education level or comorbidities were more prevalent with GERD (p < 0.001). Symptoms of severe periodontitis (OR = 1.40, 95% CI 1.28-1.52, p < 0.001) and lower frequency of tooth brushing (OR = 2.01, 95% CI 1.76-2.29, p < 0.001) were significantly associated with risk of GERD. Conclusion Symptom-based GERD is highly prevalent in the Chinese population. Overweight and smoking are major preventable risk factors for GERD. Periodontal factors are novel potential risk factors for GERD and should be given more attention in GERD prevention.

Clinical Implications of the Gastroesophageal Reflux Disease Questionnaire and Reflux Symptom Index in Patients With Suspected Laryngopharyngeal Reflux Symptoms. J Neurogastroenterol Motil 2022; 28:599-607. [PMID: 36250367 PMCID: PMC9577572 DOI: 10.5056/jnm21235] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 02/24/2022] [Accepted: 03/07/2022] [Indexed: 11/20/2022] Open
Abstract
Background/Aims To evaluate the usefulness of gastroesophageal reflux disease questionnaire (GerdQ) and reflux symptom index (RSI) for diagnosis of gastroesophageal reflux disease (GERD) in patients with suspected laryngopharyngeal reflux (LPR) symptoms (cough, hoarseness, globus, and throat pain). Methods A total of 98 patients with LPR symptoms were incorporated from either gastroenterology or otorhinolaryngology clinic. Patient’s laryngoscopic findings were graded by reflux finding score (RFS), and RFS ≥ 7 was considered as positive LPR. Erosive esophagitis on endoscopy or abnormal results on ambulatory impedance-pH monitoring were used as diagnostic criteria for GERD. Esophageal motor function was evaluated using high-resolution esophageal manometry. Results Ninety-three (94.9%) of the 98 subjects were diagnosed as LPR by RFS, but only 15 (15.3%) had GERD. For GerdQ, the cutoff value of 9 showed the highest area under curve (AUC) to diagnose GERD by receiver operating curve analysis (AUC = 0.565); the sensitivity, specificity, positive predictive value, and negative predictive value were unsatisfactory (50.0%, 70.7%, 22.6%, and 89.2%, respectively.) RSI also showed poor performance in diagnosing GERD; the cutoff value of 25 showed the highest yield (AUC = 0.581); the sensitivity, specificity, positive predictive value, and negative predictive value were 42.9%, 79.3%, 26.1%, and 89.0%, respectively. Ineffective esophageal motility was frequently observed (69 of 98, 70.4%), but there was no difference in esophageal motility parameters between GERD and non-GERD patients. Conclusions In patients with LPR symptoms, significant discrepancies are observed between laryngoscopic diagnosis and GERD. In this population, neither GerdQ nor RSI is useful in diagnosing GERD.

Abstract
Globus is a non-painful sensation of a tightness or a lump/foreign body in the throat that is not associated with dysphagia and may actually improve during meals. While several otorhinolaryngologic, thyroid, and esophageal disorders have been linked to globus, cause-and-effect relationships are difficult to establish. Consequently, though part of the evaluation, objective otorhinolaryngologic and esophageal testing is often negative. The presence of alarm symptoms, particularly pain, weight loss, dysphagia, or odynophagia is indications for objective testing. A diagnosis of idiopathic globus requires exclusion of pharyngeal, laryngeal, and esophageal disorders with laryngoscopy, endoscopy, high-resolution manometry, barium radiography, and/or ambulatory reflux monitoring. A trial of acid-suppressive therapy may be reasonable in the absence of alarm symptoms, especially if concurrent reflux symptoms are identified. Ablation of heterotopic gastric mucosa in the proximal esophagus has been reported to improve globus symptoms. Beyond these specific approaches, further management of idiopathic globus consists of reassurance, neuromodulators, and complementary approaches. Globus has a benign course with no long-term consequences, and the overall prognosis is good as the magnitude of symptoms may decline over time.

Abstract
Introduction Clinical questionnaires have some limitations compared to instrumental diagnosis of gastroesophageal reflux disease (GERD), but clinical diagnosis of GERD based on typical symptoms is pragmatic and well-established by societal guidelines. Aim To study the diagnostic value and provide comparative analysis of GerdQ and GSRS questionnaires regarding the GERD diagnostics based on a comparison of the questionnaires with the results of intraluminal oesophageal impedance-pH monitoring in Ukraine. Material and methods Twenty-eight patients (11 men and 17 women with a mean age of 47 ±2.4 years and a mean body mass index of 25.6 ±1.1 kg) filled in the GerdQ and GSRS questionnaires and underwent 24-hour multichannel intraluminal oesophageal impedance-pH monitoring. Results The GerdQ questionnaire showed a significantly strong correlation between the total score of the questionnaire and the key indicators of 24-hour impedance-pH monitoring: AET (rs = 0.793), acid reflux episodes (rs = 0.796), and liquid reflux episodes (rs = 0.730). Correlation of reflux syndrome according to the GSRS questionnaire was established between the acid reflux episodes (rs = 0.530), the episodes of all fluid refluxes (rs = 0.598), and AET (rs = 0.560), but the strength of the correlation relationships is weaker. The GerdQ questionnaire showed a sensitivity of 78.6%, specificity of 92.9%, and accuracy (diagnostic efficiency) of 85.7%. Conclusions The use of the GerdQ questionnaire for the diagnosis of GERD is optimal in everyday practice for deciding whether to prescribe “ex juvantibus” therapy or whether to use instrumental examination methods (upper endoscopy, oesophageal pH monitoring, oesophageal impedance-pH monitoring).
