Evaluation and Management of Nonulcer Dyspepsia - Article

ABSTRACT: When no organic cause for dyspepsia is found, the condition generally is considered to be functional, or idiopathic. Nonulcer dyspepsia can cause a variety of symptoms, including abdominal pain, bloating, nausea, and vomiting. Many patients with nonulcer dyspepsia have multiple somatic complaints, as well as symptoms of anxiety and depression. Extensive diagnostic testing is not recommended, except in patients with serious risk factors such as dysphagia, protracted vomiting, anorexia, melena, anemia, or a palpable mass. In these patients, endoscopy should be considered to exclude gastroesophageal reflux disease, peptic or duodenal ulcer, and gastric cancer. In patients without risk factors, consideration should be given to empiric therapy with a prokinetic agent (e.g., metoclopramide), an acid suppressant (histamine-H2 receptor antagonist), or an antimicrobial agent with activity against Helicobacter pylori. Treatment of patients with H. pylori infection and nonulcer dyspepsia (rather than peptic ulcer) is controversial and should be undertaken only when the pathogen has been identified. Psychotropic agents should be used in patients with comorbid anxiety or depression. Treatment of nonulcer dyspepsia can be challenging because of the need to balance medical management strategies with treatments for psychologic or functional disease.


Update on Helicobacter pylori Treatment - Article

ABSTRACT: One half of the world's population has Helicobacter pylori infection, with an estimated prevalence of 30 percent in North America. Although it is unclear whether eradication of H. pylori improves symptoms in patients with nonulcer dyspepsia, there is strong evidence that eradication of this bacteria improves healing and reduces the risk of recurrence or rebleeding in patients with duodenal or gastric ulcer. A "test-and-treat" strategy is recommended for most patients with undifferentiated dyspepsia. With this approach, patients undergo a noninvasive test for H. pylori infection and, if positive, are treated with eradication therapy. This strategy reduces the need for antisecretory medications as well as the number of endoscopies. The urea breath test or stool antigen test is recommended. Until recently, the recommended duration of therapy for H. pylori eradication was 10 to 14 days. Shorter courses of treatment (i.e., one to five days) have demonstrated eradication rates of 89 to 95 percent with the potential for greater patient compliance. A one-day treatment course consists of bismuth subsalicylate, amoxicillin, and metronidazole, all given four times with a one-time dose of lansoprazole. In children with documented H. pylori infection, however, all regimens should continue to be prescribed for seven to 14 days until short-course treatment is studied and its effectiveness has been established in this population.

Evaluation and Management of Dyspepsia - Article

ABSTRACT: Dyspepsia, often defined as chronic or recurrent discomfort centered in the upper abdomen, can be caused by a variety of conditions. Common etiologies include peptic ulcers and gastroesophageal reflux. Serious causes, such as gastric and pancreatic cancers, are rare but must also be considered. Symptoms of possible causes often overlap, which can make initial diagnosis difficult. In many patients, a definite cause is never established. The initial evaluation of patients with dyspepsia includes a thorough history and physical examination, with special attention given to elements that suggest the presence of serious disease. Endoscopy should be performed promptly in patients who have "alarm symptoms" such as melena or anorexia. Optimal management remains controversial in young patients who do not have alarm symptoms. Although management should be individualized, a cost-effective initial approach is to test for Helicobacter pylori and treat the infection if the test is positive. If the H. pylori test is negative, empiric therapy with a gastric acid suppressant or prokinetic agent is recommended. If symptoms persist or recur after six to eight weeks of empiric therapy, endoscopy should be performed.

Update on the Evaluation and Management of Functional Dyspepsia - Article

ABSTRACT: Dyspepsia affects up to 40 percent of adults each year and is often diagnosed as functional (nonulcer) dyspepsia. The defining symptoms are postprandial fullness, early satiation, or epigastric pain or burning in the absence of causative structural disease. These symptoms may coexist with symptoms of functional gastrointestinal disorders, such as gastroesophageal reflux and irritable bowel syndrome, as well as anxiety and depression. The history and physical examination can help identify other possible causes of the symptoms. Warning signs of serious disease, such as cancer, are unintended weight loss, progressive dysphagia, persistent vomiting, evidence of gastrointestinal bleeding, and a family history of cancer. In these cases, more extensive laboratory investigation, imaging, and endoscopy should be considered as clinically indicated. During the initial evaluation, a test-and-treat strategy to identify and eradicate Helicobacter pylori infection is more effective than empiric treatment and more cost-effective than initial endoscopy. Eradication of H. pylori helps one out of 15 patients with functional dyspepsia diagnosed by endoscopy, but may not be cost-effective. Treatment options that may be beneficial for functional dyspepsia include histamine H2 blockers, proton pump inhibitors, and prokinetic agents. Although psychotropic medications and psychological interventions have no proven benefit in patients with functional dyspepsia, they are appropriate for treating common psychiatric comorbidities.
