Role of clinical presentation in diagnosing reflux-related non-cardiac chest pain

Health-related quality of life in gastroesophageal reflux patients with noncardiac chest pain: Emphasis on the role of psychological distress

AIM

To investigate the effects of depression and anxiety on health-related quality of life (QoL) in gastroesophageal reflux disease (GERD) patients and those suffering from cardiac (CCP) and noncardiac (NCCP) chest pain in Wuhan, China.

METHODS

In this cross-sectional study, a total of 358 consecutive patients with GERD were enrolled in Wuhan, China, of which 176 subjects had complaints of chest pain. Those with chest pain underwent coronary angiography and were divided into a CCP group (52 cases) and NCCP group (124 cases). Validated GERD questionnaires were completed, and the 36-item Short-Form Health Survey and Hospital Anxiety/Depression Scale were used for evaluation of QoL and psychological symptoms, respectively.

RESULTS

There were similar ratios and levels of depression and anxiety in GERD with NCCP and CCP. However, the QoL was obviously lower in GERD with CCP than NCCP (48.34 ± 17.68 vs 60.21 ± 20.27, P < 0.01). In the GERD-NCCP group, rather than the GERD-CCP group, the physical and mental QoL were much poorer in subjects with depression and/or anxiety than those without anxiety or depression. Anxiety and depression had strong negative correlations with both physical and mental health in GERD-NCCP (all P < 0.01), but only a weak relationship with mental components of QoL in GERD-CCP.

CONCLUSION

High levels of anxiety and depression may be more related to the poorer QoL in GERD patients with NCCP than those with CCP. This highlights the importance of evaluation and management of psychological impact for improving QoL in GERD-NCCP patients.

Age, Gender and Women's Health and the Patient

Patients with functional gastrointestinal disorders (FGIDs) often experience distress, reduced quality of life, a perceived lack of validation, and an unsatisfactory experience with health care providers. A health care provider can provide the patient with a framework in which to understand and legitimize their symptoms, remove self-doubt or blame, and identify factors that contribute to symptoms that the patient can influence or control. This framework is implemented with the consideration of important factors that impact FGIDs, such as gender, age, society, and the patient's perspective. Although the majority of FGIDs, including globus, rumination syndrome, IBS, bloating, constipation, functional abdominal pain, sphincter of Oddi dyskinesia, pelvic floor dysfunction, and extra-intestinal manifestations, are more prevalent in women than men, functional chest pain, dyspepsia, vomiting, and anorectal pain do not appear to vary by gender. Studies suggest sex differences in somatic but not visceral pain perception, motility, and central processing of visceral pain; although further research is required in autonomic nervous system dysfunction, genetics and immunologic/microbiome. Gender differences in response to psychological treatments, antidepressants, fiber, probiotics, and anticholinergics have not been adequately studied. However, a greater clinical response to 5-HT3 antagonists but not 5-HT4 agonists has been reported in women compared with men.

Screening and Identifying Erosive Esophagitis in Children with Non-cardiac Chest Pain

Non-cardiac chest pain is a common disorder that leads to costly evaluations to distinguish it from cardiac pain. The present study aimed to clarify the clinical characteristics of erosive esophagitis in children with non-cardiac chest pain. Ninety nine patients (mean age, 9.55 ± 2.95 years, 49 girls) with non-cardiac chest pain were enrolled. Patients were classified into two groups: erosive esophagitis and non-erosive esophagitis-related non-cardiac chest pain by esophagogastroduodenoscopy. Children in the erosive esophagitis-related non-cardiac chest pain group were significantly older (10.95 ± 2.54 years vs. 8.52 ± 2.83 years). Multivariate logistic regression analysis identified the following predictors of gastroesophageal reflux: chest pain related to sleep (odds ratio = 18.05, 95% confidence interval: 3.18-102.49); unfavorable dietary habits (odds ratio = 7.11, 95% confidence interval: 1.53-32.87); chest pain related to food (odds ratio = 5.09, 95% confidence interval: 1.37-18.86); epigastric pain (odds ratio = 3.73, 95% confidence interval: 1.12-12.33); and nausea, vomiting, and/or regurgitation (odds ratio = 4.35, 95% confidence interval: 1.22-15.54). Gastroesophageal reflux disease should be considered first in children with non-cardiac chest pain. Children with gastroesophageal reflux disease should receive medical treatment and lifestyle modifications.

An epidemiological study of gastroesophageal reflux disease and related risk factors in urban population of mashhad, iran

Background:

Gastroesophageal Reflux Disease (GERD) is a chronic and common disease, which is characterized by heartburn and regurgitation. In the last couple of decades, GERD has received much attention and studies have shown an increase in its prevalence. Although there have been a few studies on the prevalence of GERD in Iran, no study has yet been done in the northeastern part of the country. The aim of our study was to evaluate the prevalence of GERD and its risk factors in a population from Mashhad.

Objectives:

To evaluate the epidemiology of GERD based on a population study in Mashhad.

Patients and Methods:

This was a cross sectional descriptive study conducted in 2010. In total, 2500 participants were selected based on cluster sampling. Modified and validated Mayo Clinic questionnaire for GERD was used for data collection. Overall, 1685 questionnaires were retrieved. Fifty-one participants were excluded because of pregnancies, history of abdominal surgery and being less than 18 years old. We analyzed data using the SPSS software version 16. Prevalence of GERD and significant risk factors (P value < 0.05) were determined.

Results:

In total, 420 participants (25.7%) had GERD symptoms. Risk factors with significant effects consisted of smoking, consumption of non-steroidal anti-inflammatory drugs (NASIDs), overeating, chronic diseases, tea and coffee consumption and GERD in spouse.

Conclusions:

The prevalence of GERD among people living in Mashhad was above the average prevalence in other cities of Iran. However, risk factors seemed to be similar to those reported by other studies.

Diagnostic indicators of non-cardiovascular chest pain: a systematic review and meta-analysis

BACKGROUND

Non-cardiovascular chest pain (NCCP) has a high healthcare cost, but insufficient guidelines exist for its diagnostic investigation. The objective of the present work was to identify important diagnostic indicators and their accuracy for specific and non-specific conditions underlying NCCP.

METHODS

A systematic review and meta-analysis were performed. In May 2012, six databases were searched. Hand and bibliography searches were also conducted. Studies evaluating a diagnostic test against a reference test in patients with NCCP were included. Exclusion criteria were having <30 patients per group, and evaluating diagnostic tests for acute cardiovascular disease. Diagnostic accuracy is given in likelihood ratios (LR): very good (LR+ >10, LR- <0.1); good (LR + 5 to 10, LR- 0.1 to 0.2); fair (LR + 2 to 5, LR- 0.2 to 0.5); or poor (LR + 1 to 2, LR- 0.5 to 1). Joined meta-analysis of the diagnostic test sensitivity and specificity was performed by applying a hierarchical Bayesian model.

RESULTS

Out of 6,316 records, 260 were reviewed in full text, and 28 were included: 20 investigating gastroesophageal reflux disorders (GERD), 3 musculoskeletal chest pain, and 5 psychiatric conditions. Study quality was good in 15 studies and moderate in 13. GERD diagnosis was more likely with typical GERD symptoms (LR + 2.70 and 2.75, LR- 0.42 and 0.78) than atypical GERD symptoms (LR + 0.49, LR- 2.71). GERD was also more likely with a positive response to a proton pump inhibitor (PPI) test (LR + 5.48, 7.13, and 8.56; LR- 0.24, 0.25, and 0.28); the posterior mean sensitivity and specificity of six studies were 0.89 (95% credible interval, 0.28 to 1) and 0.88 (95% credible interval, 0.26 to 1), respectively. Panic and anxiety screening scores can identify individuals requiring further testing for anxiety or panic disorders. Clinical findings in musculoskeletal pain either had a fair to moderate LR + and a poor LR- or vice versa.

CONCLUSIONS

In patients with NCCP, thorough clinical evaluation of the patient's history, symptoms, and clinical findings can indicate the most appropriate diagnostic tests. Treatment response to high-dose PPI treatment provides important information regarding GERD, and should be considered early. Panic and anxiety disorders are often undiagnosed and should be considered in the differential diagnosis of chest pain.

Noncardiac chest pain: epidemiology, natural course and pathogenesis

Noncardiac chest pain is defined as recurrent chest pain that is indistinguishable from ischemic heart pain after a reasonable workup has excluded a cardiac cause. Noncardiac chest pain is a prevalent disorder resulting in high healthcare utilization and significant work absenteeism. However, despite its chronic nature, noncardiac chest pain has no impact on patients' mortality. The main underlying mechanisms include gastroesophageal reflux, esophageal dysmotility and esophageal hypersensitivity. Gastroesophageal reflux disease is likely the most common cause of noncardiac chest pain. Esophageal dysmotility affects only the minority of noncardiac chest pain patients. Esophageal hypersensitivity may be present in non-GERD-related noncardiac chest pain patients regardless if esophageal dysmotility is present or absent. Psychological co-morbidities such as panic disorder, anxiety, and depression are also common in noncardiac chest pain patients and often modulate patients' perception of disease severity.

An algorithm for the diagnosis and management of chest pain in primary care

This article focuses on the key clinical and investigatory features that help differentiate the multiple causes of chest pain in adults in assessment of patients with undifferentiated chest pain in primary care using history, physical examination, and basic initial investigations. The initial treatment of many of the causes is discussed. Some treatments not only relieve symptoms but also provide further diagnostic information based on the response to treatment. Guidance for referral for specialist assessment and further investigations is provided, but the diagnostic usefulness of these measures is not discussed.

Noncardiac chest pain: gastroesophageal reflux disease

Noncardiac chest pain (NCCP) is not only a difficult disorder to define but is also complex in characterization and treatment. Patients with NCCP are a challenge to primary care and subspecialty services such as cardiology and gastroenterology. NCCP is often a heterogeneous disorder with many potential causes including gastroenterologic diagnoses. This article presents the current evidence for gastroesophageal reflux disease as a cause of NCCP and highlights the best currently available tests for this group of patients.

Heartburn or angina? Differentiating gastrointestinal disease in primary care patients presenting with chest pain: a cross sectional diagnostic study

BACKGROUND

Gastrointestinal (GI) disease is one of the leading aetiologies of chest pain in a primary care setting. The aims of the study are to describe clinical characteristics of GI disease causing chest pain and to provide criteria for clinical diagnosis.

METHODS

We included 1212 consecutive patients with chest pain aged 35 years and older attending 74 general practitioners (GPs). GPs recorded symptoms and findings of each patient and provided follow up information. An independent interdisciplinary reference panel reviewed clinical data of each patient and decided about the aetiology of chest pain. Multivariable regression analysis was performed to identify clinical predictors that help to rule in or out the diagnosis of GI disease and Gastroesophageal Reflux Disease (GERD).

RESULTS

GI disease was diagnosed in 5.8% and GERD in 3.5% of all patients. Most patients localised the pain retrosternal (71.8% for GI disease and 83.3% for GERD). Pain worse with food intake and retrosternal pain radiation were associated positively with both GI disease and GERD; retrosternal pain localisation, vomiting, burning pain, epigastric pain and an average pain episode < 1 hour were associated positively only with GI disease. Negative associations were found for localized muscle tension (GI disease and GERD) and pain getting worse on exercise, breathing, movement and pain location on left side (only GI disease).

CONCLUSIONS

This study broadens the knowledge about the diagnostic accuracy of selected signs and symptoms for GI disease and GERD and provides criteria for primary care practitioners in rational diagnosis.

The Italian validation of the Montreal Global definition and classification of gastroesophageal reflux disease

BACKGROUND AND AIMS

Recently, a Global definition and a classification of gastroesophageal reflux disease (GERD) were developed by Montreal Consensus Group, composed of international expert gastroenterologists. Guidelines and consensus documents are, however, infrequently accepted and adopted at a local level. The aim of this study was to measure the acceptance of Montreal Global definition of GERD consensus document by specialists in a single country (Italy) and to measure the linguistic, scientific, and practical differences between the international consensus document and the Italian version.

METHODS

A 2-day meeting was held in June 2007 in Rome, Italy, attended by 147 Italian physicians who were experts in gastroenterology. They reviewed the individual original statements in their Italian translation and then voted on the statement using the scoring system used by the Montreal Consensus Group (6-point Likert scale). Voting was performed at baseline and after an analytical discussion on each statement, led by six internationally renowned experts. Consensus was defined as an agreement with a statement by at least two-thirds of the group. Results were compared with the Montreal statements.

RESULTS AND DISCUSSION

The level of consensus was already extremely high at the first vote (>90% with the two-thirds threshold). The level of agreement at the second vote increased slightly. The maximum variation between two votes was 33% (of increase from first to second round, 59-92%). The high level of agreement could be because of both the general acceptance of Montreal Consensus by scientific community, and the new scientific evidences published after the Montreal report, which fit with the original statements.

CONCLUSION

This study is the first national linguistic validation of the Montreal Global definition of GERD and is also proof of its scientific validity, based on the same methodology used to create the Montreal statements. It also suggests that evidence-based International disease classification systems can be applied to local settings after validation by local experts.

Extraesophageal GERD

The manifestations of gastroesophageal reflux disease (GERD) have been classified into either esophageal or extraesophageal syndromes. Cough, reflux laryngitis, and asthma have been classified as extraesophageal syndromes, whereas reflux chest pain has been classified as a symptomatic syndrome of GERD. In extraesophageal syndromes, patients usually do not display the classic symptoms of reflux, such as heartburn and regurgitation. Upper gastrointestinal endoscopy and pH monitoring, when used to diagnose reflux in patients with symptoms not classic for GERD, have proved to have poor sensitivity and are often not diagnostically helpful. In contrast, an empiric trial of proton pump inhibitors is a well-established, cost-effective tool.

Noncardiac chest pain

Noncardiac chest pain (NCCP) affects approximately 1 quarter of the adult population in the United States. The pathophysiology of the disorder remains to be fully elucidated. Identified underlying mechanisms for esophageal pain include gastroesophageal reflux disease (GERD), esophageal dysmotility, and visceral hypersensitivity. Aggressive antireflux treatment has been the main therapeutic strategy for GERD-related NCCP. NCCP patients with or without spastic esophageal motor disorders are responsive to pain modulators. The value of botulinum toxin injection, endoscopic treatment for GERD, and antireflux surgery in alleviating NCCP symptoms is limited.
