Health-related anxiety and the effect of open-access endoscopy in US patients with dyspepsia

United European Gastroenterology (UEG) and European Society for Neurogastroenterology and Motility (ESNM) consensus on functional dyspepsia

BACKGROUND

Functional dyspepsia (FD) is one of the most common conditions in clinical practice. In spite of its prevalence, FD is associated with major uncertainties in terms of its definition, underlying pathophysiology, diagnosis, treatment, and prognosis.

METHODS

A Delphi consensus was initiated with 41 experts from 22 European countries who conducted a literature summary and voting process on 87 statements. Quality of evidence was evaluated using the grading of recommendations, assessment, development, and evaluation (GRADE) criteria. Consensus (defined as >80% agreement) was reached for 36 statements.

RESULTS

The panel agreed with the definition in terms of its cardinal symptoms (early satiation, postprandial fullness, epigastric pain, and epigastric burning), its subdivision into epigastric pain syndrome and postprandial distress syndrome, and the presence of accessory symptoms (upper abdominal bloating, nausea, belching), and overlapping conditions. Also, well accepted are the female predominance of FD, its impact on quality of life and health costs, and acute gastrointestinal infections, and anxiety as risk factors. In terms of pathophysiological mechanisms, the consensus supports a role for impaired gastric accommodation, delayed gastric emptying, hypersensitivity to gastric distention, Helicobacter pylori infection, and altered central processing of signals from the gastroduodenal region. There is consensus that endoscopy is mandatory for establishing a firm diagnosis of FD, but that in primary care, patients without alarm symptoms or risk factors can be managed without endoscopy. There is consensus that H. pylori status should be determined in every patient with dyspeptic symptoms and H. pylori positive patients should receive eradication therapy. Also, proton pump inhibitor therapy is considered an effective therapy for FD, but no other treatment approach reached a consensus. The long-term prognosis and life expectancy are favorable.

CONCLUSIONS AND INFERENCES

A multinational group of European experts summarized the current state of consensus on the definition, diagnosis and management of FD.

Do Low-Risk Patients With Dyspepsia Need a Gastroscopy? Use of Gastroscopy for Otherwise Healthy Patients With Dyspepsia

Background

Choosing Wisely Canada (CWC) recommends not to perform gastroscopy for dyspepsia in otherwise healthy adults less than 55 years of age (2014). The aim of this study was to evaluate the use of gastroscopy in a young, healthy population with uncomplicated dyspepsia.

Methods

A retrospective review of gastroscopies completed during 3-month periods in 2015, 2016, and 2017 identified all patients undergoing gastroscopy for the primary indication of dyspepsia. Low-risk patients for dyspepsia were defined as adults, aged 18 to 54 years without alarm symptoms, comorbidities and/or abnormal imaging findings or laboratory values. Gastroscopy and pathology reports were reviewed to identify clinically actionable findings. Clinical outcomes were followed to December 31, 2018 including gastroenterology referrals, emergency room visitation and hospitalization.

Results

Among 1358 patients having a gastroscopy for dyspepsia, 480 (35%) were low-risk patients. Sixteen patients 3.3% (16/480) had a clinically actionable result found on gastroscopy or biopsy. No malignant lesions were detected. Low-risk patients were followed up for an average of 2.75 years, 8% (39/480) visited the emergency department (ED), 1% (3/480) of patients were admitted to hospital and 12% (59/480) of patients were re-referred for a dyspepsia-related concern.

Interpretation

A high rate of low yield, high cost, invasive endoscopic investigations were performed in this population of otherwise healthy patients under age 55 years. These data suggest limited uptake of current recommendations against the routine use of gastroscopy to investigate dyspepsia.

Web-Based Educational Intervention for Patients With Uninvestigated Dyspepsia Referred for Upper Gastrointestinal Tract Endoscopy: A Randomized Clinical Trial

IMPORTANCE

Diagnostic yield of upper gastrointestinal (GI) tract endoscopy for uninvestigated dyspepsia is low, and its clinical implications are limited. There is an unmet need for better strategies to reduce the volume of upper GI tract endoscopic procedures for dyspepsia.

OBJECTIVE

To study the effectiveness of a web-based educational intervention as a tool to reduce upper GI tract endoscopy in uninvestigated dyspepsia.

DESIGN, SETTING, AND PARTICIPANTS

This open-label, multicenter, randomized clinical trial enrolled participants between November 1, 2017, and March 31, 2019, with follow-up 52 weeks after randomization, at 4 teaching hospitals in the Netherlands. Participants included patients with uninvestigated dyspeptic symptoms who were referred for upper GI tract endoscopy by their general health care clinician without prior consultation of a gastroenterologist. A total of 119 patients, aged 18 to 69 years, were included. Patients were excluded if any of the following red flag symptoms were present: (indirect) signs of upper GI tract hemorrhage (hematemesis, melena, hematochezia, or anemia), unintentional weight loss of 5% or higher of normal body weight during a period of 6 to 12 months, persistent vomiting, dysphagia, or jaundice.

INTERVENTIONS

Patients were randomly assigned (1:1) to education (intervention) or upper GI tract endoscopy (control). Education consisted of a self-managed web-based educational intervention, containing information on gastric function, dyspepsia, and upper GI tract endoscopy.

MAIN OUTCOMES AND MEASURES

Difference in the proportion of upper GI tract endoscopy procedures between those who received access to the web-based educational intervention and those who did not at 12 weeks and 52 weeks after randomization, analyzed in the intention-to-treat population. Secondary outcomes included quality of life (Nepean Dyspepsia Index) and symptom severity (Patient Assessment of Gastrointestinal Disorders Symptom Severity Index) measured at baseline and 12 weeks.

RESULTS

Of 119 patients included (median age, 48 years [interquartile range, 37-56 years]; 48 men [40%]), 62 were randomized to web-based education (intervention) and 57 to upper GI tract endoscopy (control). Significantly fewer patients compared with controls underwent upper GI tract endoscopy after using the web-based educational intervention: 24 (39%) vs 47 (82%) (relative risk, 0.46; 95% CI, 0.33-0.64; P < .001). Symptom severity and quality of life improved equivalently in both groups. One additional patient in the intervention group required upper GI tract endoscopy during follow-up.

CONCLUSIONS AND RELEVANCE

Findings of this study indicate that web-based patient education is an effective tool to decrease the need for upper GI tract endoscopy in uninvestigated dyspepsia.

Conclusions and Inferences

A multinational group of European experts summarized the current state of consensus on the definition, diagnosis and management of FD.

Current knowledge

Functional dyspepsia is one of the most common conditions encountered in clinical practice.

There is a lack of guidance for clinicians in guiding diagnosis and treatment of this prevalent condition.

No treatments are currently approved for the treatment of functional dyspepsia in Europe.

What is new here

A Delphi panel consisting of 41 experts from 22 European countries established the level of consensus on 87 statements regarding functional dyspepsia.

The statements reaching consensus serve to guide clinicians in recognizing, diagnosing and treating FD in clinical practice.

Endoscopy is mandatory for establishing a firm diagnosis of functional dyspepsia D, but in primary care patients without alarm symptoms or risk factors can be managed without endoscopy.

Helicobacter pylori status should be determined in every patient with dyspeptic symptoms and H. Pylori positive patients should receive eradication therapy.

Proton pump inhibitor‐therapy is considered an effective therapy for FD, but no other treatment approach reached consensus support.

Short-term effect of a negative colonoscopy in patients with functional constipation

The yield of colonoscopy for neoplasia among patients with chronic constipation is very low. However, a negative colonoscopy may benefit these patients by decreasing anxiety and thereby alleviating constipation symptoms. We performed a prospective study to characterize the effect of a negative colonoscopy in patients with functional constipation. Seventy-five patients with chronic constipation were enrolled, and 69 patients were diagnosed with functional constipation through the Rome III criteria. After excluding patients whose constipation symptoms were affected by medications (e.g., laxatives, prokinetics), 45 patients were included in the study. Among the 45 patients, the average health-related anxiety score decreased from 21.0 to 15.6 at 1 week after colonoscopy (P < 0.01). Sustained improvement was observed in anxiety scores at 1 month (14.0), 2 months (12.4), and 6 months (11.2). Mean constipation symptom score was also decreased at 1 week (8.7), 1 month (8.0), 2 months (7.6), and 6 months (6.8) compared with the precolonoscopy period (11.5; P < 0.01). These results suggest that a negative colonoscopy in patients with functional constipation is associated with a decline in health-related anxiety and constipation symptom scores.

Low Prevalence of Clinically Significant Endoscopic Findings in Outpatients with Dyspepsia

Background. The value of endoscopy in dyspeptic patients is questionable. Aims. To examine the prevalence of significant endoscopic findings (SEFs) and the utility of alarm features and age in predicting SEFs in outpatients with dyspepsia. Methods. A retrospective analysis of outpatient adults who had endoscopy for dyspepsia. Demographic variables, alarm features, and endoscopic findings were recorded. We defined SEFs as peptic ulcer disease, erosive esophagitis, malignancy, stricture, or findings requiring specific therapy. Results. Of 650 patients included in the analysis, 51% had a normal endoscopy. The most common endoscopic abnormality was nonerosive gastritis (29.7%) followed by nonerosive duodenitis (7.2%) and LA-class A esophagitis (5.4%). Only 10.2% had a SEF. Five patients (0.8%) had malignancy. SEFs were more likely present in patients with alarm features (12.6% versus 5.4%, p = 0.004). Age ≥ 55 and presence of any alarm feature were associated with SEFs (aOR 1.8 and 2.3, resp.). Conclusion. Dyspeptic patients have low prevalence of SEF. The presence of any alarm feature and age ≥ 55 are associated with higher risk of SEF. Endoscopy in young patients with no alarm features has a low yield; these patients can be considered for nonendoscopic approach for diagnosis and management.

The influence of escort during upper endoscopy and colonoscopy on patient satisfaction and anxiety

AIM

Endoscopy, including esophagogastroduodenoscopy (EGD) and colonoscopy (CS), is a diagnostic and treatment method for various diseases. We aimed to evaluate the effects of the presence of an escort by the patient on patients' satisfaction and anxiety level before and after upper endoscopy and CS.

SUBJECTS AND METHODS

Patients who referred to the Hajar Hospital for elective EGD and CS were recruited. The patients were divided into two groups: The first group underwent endoscopy/CS with an escort beside the patient and the escort was waiting in the waiting room in the second group. After interventions, patients' and their escort's levels of anxiety and satisfaction were evaluated. Anxiety level was compared before and after endoscopy.

RESULTS

Of 211 patients, 106 were referred for EGD and 105 for CS. Anxiety was same in both groups before the interventions (P > 0.05), which decreased in both after the EGD or CS (P < 0.05). Anxiety reduction after CS was influenced by the presence of the escort and the level of anxiety was less in this group than other group (P < 0.05). Satisfaction of the EGD and CS in the group that had an escort by their side was more than the other (P < 0.05). Escorts had a moderate level of anxiety in both groups with a marked reduction after endoscopy and CS (P < 0.05). However, the level of anxiety before and after endoscopy was similar in both groups (P > 0.05).

CONCLUSION

Having an escort at the time of endoscopy or CS appears to be an effective costless complication-free measure for increasing satisfaction and reducing anxiety in patients.

Emerging drugs for functional dyspepsia

INTRODUCTION

Functional dyspepsia (FD) is a relatively common gastrointestinal clinical condition that remains poorly understood. Controversies remain regarding the definition, pathophysiology and optimum treatment. The current treatment of FD is limited and no established regimen is available.

AREAS COVERED

Recent advances have improved our understanding of the pathophysiology of the disease and have led to the development of newer tailored therapies. Novel agents such as the motilin receptor agonist camicinal and the muscarinic M1 and M2 receptor antagonist acotiamide appear promising; however, the need for a safe and efficacious treatment remains largely unmet. This review describes the currently available management options for FD and critically evaluates emerging therapies.

EXPERT OPINION

The optimal treatment for FD is yet to be determined. A proton pump inhibitor or a prokinetic agent constitutes primary treatment. Helicobacter pylori testing and eradication is recommended. Based on currently available data, acotiamide appears promising, particularly in postprandial distress syndrome. Further large-scale multicentered trials are required to define the duration of treatment and the side-effect profile.

An Evidence-Based Approach to the Management of Functional Dyspepsia Associated With Helicobacter pylori Infection

Background

Functional dyspepsia is defined as at least a 3-month history of dyspepsia without structural explanation for the symptoms, and it accounts for most cases of dyspepsia. We designed this study to investigate functional dyspepsia among a Chinese population in Taiwan.

Methods

Data from the medical records of 1,143 adult patients who underwent transoral upper endoscopy for symptoms of dyspepsia in our hospital were retrospectively analyzed between January 2008 and December 2008. Exclusion criteria were structural gastrointestinal and hepatobiliary abnormalities, prior gastric surgery or history of chronic medication use.

Results

Patients were mainly in the third and fourth decades of life. More female patients were noted than male patients (ratio 2:1). The rate of Helicobacter pylori infection was 18.5%. The rate of response to therapeutic agents, including proton pump inhibitors, H2-receptor antagonists and prokinetic agents, ranged from 69% to 77% among all cases. Patients who underwent H. pylori eradication therapy (88.8%) had a significantly higher rate of symptom improvement than those without H. pylori infection (77.5%).

Conclusion

Cases with functional dyspepsia have the characteristics of middle age, female predominance, a relatively lower H. pylori infection rate and a positive response to H. pylori eradication therapy.

Evidence-based approach to dyspepsia: from Helicobacter pylori to functional disease

Patients with dyspepsia may present with associated complaints of abdominal pain, bloating, fullness, acid reflux, and epigastric tenderness on examination. The evaluation of patients with dyspepsia includes taking a comprehensive history and performing a physical examination. Although taking a patient history has its limitations in making an accurate diagnosis, it is useful in guiding the selection of subsequent diagnostic tests. Differential diagnoses of dyspepsia are best addressed using an anatomical approach. Patients with chronic dyspepsia lasting > 1 month should be evaluated for the presence of alarm features. Alarm features mandate an upper gastrointestinal endoscopy examination, as these may be suggestive of a malignancy. In patients without alarm features, a Helicobacter pylori test-and-treat strategy is cost-effective if the prevalence of H. pylori infection is high. Tests for H. pylori infection can be divided into non-invasive and minimally invasive tests. Many different antibiotic combination therapies (eg, triple therapy, quadruple therapy, levofloxacin-based therapy, sequential therapy, concomitant therapy, and probiotics with eradication therapy) are now available for the eradication of H. pylori infection. In patients who are symptomatic without an organic pathology, functional dyspepsia and other causes of abdominal pain need to be considered. Functional dyspepsia is best managed using a multifaceted approach by establishing a good physician-patient relationship, dietary and lifestyle interventions, medical therapy, psychotherapy, and the use of psychotropic medications. This review rationalizes the current-day recommendations for the evaluation and management of patients with dyspepsia in a clinical setting.

Can clinical features stratify use of endoscopy for dyspeptic patients with high background prevalence of upper gastrointestinal cancer?

BACKGROUND

Whether clinical features can stratify priority of endoscopy remains controversial for dyspeptic patients with high background prevalence of upper gastrointestinal cancer.

AIM

To examine the predictive performance of clinical features for cancerous lesions in dyspeptic patients in Taiwan.

METHODS

Between April 2008 and July 2009, 2530 consecutive dyspeptic outpatients underwent prospective evaluation with standardized questionnaire and then upper gastrointestinal endoscopy. Performance of using age thresholds and alarm symptoms to predict malignancy was determined. Independent risk factors associated with malignancy and those with negative endoscopic findings were identified.

RESULTS

Malignant lesions were found in 31 patients (1.2%) and were independently associated with age, male gender, gastrointestinal bleeding, weight loss, and alcohol consumption. Any symptom of weight loss, bleeding and dysphagia, or simply age >45 years predicted 97% of cancer cases, with the sensitivity, specificity, positive and negative predictive values being 96.8%, 29.3%, 1.7%, and 99.9%, respectively. This strategy achieved a low negative likelihood ratio (0.11) and a high diagnostic odds ratio (12.45). Negative endoscopic finding (n=1377, 54.4%) was independently associated with younger age, female gender, no use of non-steroidal anti-inflammatory drug, and no tobacco or alcohol consumption.

CONCLUSIONS

Absence of weight loss, dysphagia, and gastrointestinal bleeding predicts low likelihood of malignancy in dyspeptic Taiwanese patients aged <45 years.

Dyspepsia: organic versus functional

Dyspepsia is the medical term for difficult digestion. It consists of various symptoms in the upper abdomen, such as fullness, discomfort, early satiation, bloating, heartburn, belching, nausea, vomiting, or pain. The prevalence of dyspepsia in the western world is approximately 20% to 25%. Dyspepsia can be divided into 2 main categories: "organic" and "functional dyspepsia" (FD). Organic causes of dyspepsia are peptic ulcer, gastroesophageal reflux disease, gastric or esophageal cancer, pancreatic or biliary disorders, intolerance to food or drugs, and other infectious or systemic diseases. Pathophysiological mechanisms underlying FD are delayed gastric emptying, impaired gastric accommodation to a meal, hypersensitivity to gastric distension, altered duodenal sensitivity to lipids or acids, altered antroduodenojenunal motility and gastric electrical rhythm, unsuppressed postprandial phasic contractility in the proximal stomach, and autonomic nervous system-central nervous system dysregulation. Pathogenetic factors in FD are genetic predisposition, infection from Helicobacter pylori or other organisms, inflammation, and psychosocial factors. Diagnostic evaluation of dyspepsia includes upper gastrointestinal endoscopy, abdominal ultrasonography, gastric emptying testing (scintigraphy, breath test, ultrasonography, or magnetic resonance imaging), and gastric accommodation evaluation (magnetic resonance imaging, ultrasound, single-photon emission computed tomography, and barostat). Antroduodenal manometry can be used for the assessment of the myoelectrical activity of the stomach, whereas sensory function can be evaluated with the barostat, tensostat, and satiety test. Management of FD includes general measures, acid-suppressive drugs, eradication of H. pylori, prokinetic agents, fundus-relaxing drugs, antidepressants, and psychological interventions. This review presents an update on the diagnosis of patients presenting with dyspepsia, with an emphasis on the pathophysiological and pathogenetic mechanisms of FD and the differential diagnosis with organic causes of dyspepsia. The management of uninvestigated and FD, as well as the established and new pharmaceutical agents, is also discussed.

Prevalence and sociodemographic determinants of uninvestigated dyspepsia in the Czech Republic

OBJECTIVE

There are no data on the epidemiology of dyspepsia in Central Europe. The aim of this study was to evaluate the prevalence of uninvestigated dyspepsia in a representative sample of the Czech population.

METHODS

A total of 2509 persons, aged 5-100 years, randomly selected from 30 012 individuals in the general population, entered this multicentre, prospective, questionnaire-based epidemiological study.

RESULTS

We found a 17% prevalence of long-lasting (>12 months) dyspeptic symptoms in the general population. Two subgroups were distinguished: (i) persons with dyspepsia as the only one long-lasting symptom and themselves feeling otherwise healthy (9%), mostly among younger patients (subgroup A); and (ii) patients with dyspepsia as part of the complex of previously recognized diseases (8%), mostly in older patients (subgroup B). The prevalence of dyspepsia was significantly higher among women. The excess cases of dyspepsia among the highly educated seemed to be cases of dyspepsia of subgroup A, and the higher prevalence of dyspepsia among the lower social classes was largely dyspepsia of subgroup B. Being a widow/widower had a significant effect on the risk of self-reported dyspepsia among 25-64-year-olds. No association between Helicobacter pylori infection and dyspepsia was found.

CONCLUSION

The prevalence of uninvestigated dyspepsia in the Czech Republic is comparable with data from other European countries. Clearly distinct subgroups of dyspeptic patients exist that should be further studied.

Endoscopy in GERD: Boondoggle, Diagnostic Test, or Risk Management Tool?

The role of endoscopy in reflux disease is debated. Diagnostic certainty is attractive to patients and physicians, to affirm health and to ensure the absence of serious disease, but it is expensive and the majority of patients will have no endoscopic abnormalities. Empirical treatment with acid suppression in patients with symptoms of gastroesophageal reflux disease (GERD) is now widely practiced in primary care in many countries but in others, endoscopy is mandatory to receive approval from the payors for proton pump inhibitor therapy. In patients with dysphagia, endoscopy has a role in ruling out an obstructing lesion. A "once-in-a-lifetime" endoscopy has been proposed as a way to improve our ability to diagnose Barrett's esophagus, but cost-models suggest that this strategy is not cost-effective if current surveillance guidelines are followed after the diagnosis of Barrett's esophagus is made. The role of routine endoscopic examination in GERD is therefore questionable and needs better definition in carefully designed trials.

Value of a negative colonoscopy in patients with non-specific gastrointestinal symptoms

BACKGROUND

The yield of colonoscopy for neoplasia among patients aged <50 years with non-specific gastrointestinal symptoms is very low. However, a negative colonoscopy may benefit these patients by decreasing anxiety and thereby reducing subsequent health resource utilization. This study sought to characterize the effect of a negative colonoscopy in terms of: (i) reassurance value; and (ii) decreasing health resource utilization, in patients under 50 years of age with non-specific gastrointestinal symptoms (abdominal pain, diarrhea, constipation).

METHODS

Consecutive patients, aged 18-49 years, undergoing their first colonoscopy for evaluation of non-specific gastrointestinal symptoms (abdominal pain, diarrhea, constipation) were prospectively enrolled. Health-related anxiety was evaluated before and immediately after disclosure of the negative result of colonoscopy using a validated questionnaire and at 1-, 2- and 6-month intervals postcolonoscopy by telephone follow-up. Symptom scores and health resource utilization were assessed prior to colonoscopy and at 2 and 6 months postcolonoscopy.

RESULTS

Fifty-nine patients were prospectively enrolled. Mean health anxiety score declined immediately after colonoscopy from 20.6 to 17.8. Sustained improvement was seen in anxiety scores at 1, 2 and 6 months. Symptom scores also decreased at 6 months for abdominal pain (2.3 to 1.5), diarrhea (2.3 to 1.6) and constipation (1.9 to 1.6). There was a significant decrease in all four measures of health resource utilization at 6 months postcolonoscopy.

CONCLUSIONS

Despite minimal diagnostic yield, colonoscopy for non-specific gastrointestinal symptoms in patients <50 years of age is associated with a decline in health-related anxiety and symptom scores. These effects appear to translate into reductions in health resource utilization.

A prospective 1-year follow-up study in patients with functional or organic dyspepsia: changes in gastrointestinal symptoms, mental distress and fear of serious illness

BACKGROUND

Psychosocial factors are common among patients with functional gastrointestinal disorders (FGIDs). Whether they affect the course of the disease remains unresolved.

AIM

To evaluate whether reassuring investigations of primary care patients with functional dyspepsia (FD) and organic dyspepsia (OD) influence gastrointestinal (GI) symptoms and psychological factors, and to assess whether these changes are correlated.

METHODS

Four hundred consecutive patients with dyspepsia were referred for thorough examinations. Patients completed questionnaires screening symptoms at baseline and on 1-year follow-up.

RESULTS

At baseline, there was no difference in GI symptoms, prevalence of mental distress or fear of serious illness between patients with FD or OD. On follow-up, the patients with FD had more GI symptoms, but there was no difference in mental distress or fear of serious illness. Relevant GI symptom reduction related to alleviation of mental distress (53.4% vs. 20.5%, P < 0.001) and fear of serious illness (56.5% vs. 23.7%, P = 0.002), but reached statistical significance only in patients with OD.

CONCLUSIONS

Gastrointestinal symptoms in FD patients are long lasting compared with those with organic diseases. Reassuring investigations could lower mental distress and fear of serious illness in these patients. Psychological factor change correlates with the change in GI symptom severity and is not specific to FGIDs.

Guidelines for the management of dyspepsia

Dyspepsia is a chronic or recurrent pain or discomfort centered in the upper abdomen; patients with predominant or frequent (more than once a week) heartburn or acid regurgitation, should be considered to have gastroesophageal reflux disease (GERD) until proven otherwise. Dyspeptic patients over 55 yr of age, or those with alarm features should undergo prompt esophagogastroduodenoscopy (EGD). In all other patients, there are two approximately equivalent options: (i) test and treat for Helicobacter pylori (H. pylori) using a validated noninvasive test and a trial of acid suppression if eradication is successful but symptoms do not resolve or (ii) an empiric trial of acid suppression with a proton pump inhibitor (PPI) for 4-8 wk. The test-and-treat option is preferable in populations with a moderate to high prevalence of H. pylori infection (> or =10%); empirical PPI is an initial option in low prevalence situations. If initial acid suppression fails after 2-4 wk, it is reasonable to consider changing drug class or dosing. If the patient fails to respond or relapses rapidly on stopping antisecretory therapy, then the test-and-treat strategy is best applied before consideration of referral for EGD. Prokinetics are not currently recommended as first-line therapy for uninvestigated dyspepsia. EGD is not mandatory in those who remain symptomatic as the yield is low; the decision to endoscope or not must be based on clinical judgement. In patients who do respond to initial therapy, stop treatment after 4-8 wk; if symptoms recur, another course of the same treatment is justified. The management of functional dyspepsia is challenging when initial antisecretory therapy and H. pylori eradication fails. There are very limited data to support the use of low-dose tricyclic antidepressants or psychological treatments in functional dyspepsia.

Chest pain in patients with cardiac and noncardiac disease

OBJECTIVE

To describe factors influencing chest pain expression in patients with cardiac or noncardiac disease.

METHODS

The authors conducted a case presentation and review of literature.

RESULTS

Causes of chest pain are diverse. Psychologic factors influence chest pain expression commonly in patients with or without cardiac disease.

CONCLUSIONS

Physicians and other therapists must be aware of psychologic influences on chest pain expression to provide optimal treatment to their patients.
