The incidence of peptic ulcer disease has declined over the last few decades, particularly in Western populations, most likely as a result of the decrease in Helicobacter pylori infection and the widespread use of proton-pump inhibitors (PPI) in patients with dyspepsia. The hospital admission rate for uncomplicated duodenal and gastric ulcers has significantly decreased worldwide. In contrast, admissions for complicated ulcer disease, such as bleeding peptic ulcers and perforation, remained relatively stable. Prophylactic H.?pylori eradication was found to be associated with a reduced risk of both gastric and duodenal ulcers and their complications, including bleeding in chronic users of nonsteroidal anti-inflammatory drugs. The recent Helicobacter Eradication Relief of Dyspeptic Symptoms trial presented important data relating to symptoms and quality of life of H.?pylori-positive patients with functional dyspepsia (FD) and also demonstrated significant benefits from eradication compared with the control group. The new Asian consensus report on FD recommended that dyspepsia accompanied by H.?pylori infection should be considered a separate disease entity from FD and that H.?pylori infection should be eradicated before diagnosing FD. The association of H.?pylori with gastroesophageal reflux disease (GERD) is still controversial. Treatment for H.?pylori does not seem to increase GERD symptoms or reflux esophagitis. However, documented eradication of H.?pylori appears to significantly improve GERD symptoms. Additional long-term intervention studies are needed to provide more information on which to base clinical decisions. 相似文献

OBJECTIVE: To determine (a) the advantages and disadvantages of treatment options for the eradication of Helicobacter pylori and (b) whether eradication of H. pylori is indicated in patients with duodenal ulcer, nonucler dyspepsia and gastric cancer. DATA SOURCES: A MEDLINE search for articles published in English between January 1983 and December 1992 with the use of MeSH terms Helicobacter pylori (called Campylobacter pylori before 1990) and duodenal ulcer, gastric cancer, dyspepsia and clinical trial. Six journals and Current Contents were searched manually for pertinent articles published in that time frame. STUDY SELECTION: For duodenal ulcer the search was limited to studies involving adults, studies of H. pylori eradication and randomized clinical trials comparing anti-H. pylori therapy with conventional ulcer treatment. For nonulcer dyspepsia with H. pylori infection the search was limited to placebo-controlled randomized clinical trials. DATA EXTRACTION: The quality of each study was rated independently on a four-point scale by each author. For the studies of duodenal ulcer the outcome measures assessed were acute ulcer healing and time required for healing, H. pylori eradication and ulcer relapse. For the studies of nonulcer dyspepsia with H. pylori infection the authors assessed H. pylori eradication, the symptoms used as outcome measures and whether validated outcome measures had been used. DATA SYNTHESIS: Eight trials involving duodenal ulcer met our inclusion criteria: five were considered high quality, two were of reasonable quality, and one was weak. Six trials involving nonulcer dyspepsia met the criteria, but all were rated as weak. Among treatment options triple therapy with a bismuth compound, metronidazole and either amoxicillin or tetracycline achieved the highest eradication rates (73% to 94%). Results concerning treatment indications for duodenal ulcer were consistent among all of the studies: when anti-H. pylori therapy was added to conventional ulcer treatment acute ulcers healed more rapidly. Ulcer relapse rates were dramatically reduced after H. pylori eradication. All of the studies involving nonulcer dyspepsia assessed clearance rather than eradication of H. pylori. No study used validated outcome measures. A consistent decrease in symptom severity was no more prevalent in patients in whom the organism had been cleared than in those taking a placebo. Of the studies concerning gastric cancer none investigated the effect of eradication of H. pylori on subsequent risk of gastric cancer. CONCLUSIONS: There is sufficient evidence to support the use of anti-H. pylori therapy in patients with duodenal ulcers who have H. pylori infection, triple therapy achieving the best results. There is no current evidence to support such therapy for nonulcer dyspepsia in patients with H. pylori infection. Much more attention must be paid to the design of nonulcer dyspepsia studies. Also, studies are needed to determine whether H. pylori eradication in patients with gastritis will prevent gastric cancer. 相似文献

BACKGROUND: Helicobacter pylori and nonsteroidal antiinflammatory drugs (NSAIDs) are the major causes of gastroduodenal ulcers. Studies on the benefit of eradication of H. pylori in NSAID users yielded conflicting results. OBJECTIVE: To investigate whether H. pylori eradication in patients on long-term NSAIDs reduces the incidence of gastroduodenal ulcers. METHODS: Patients on long-term NSAID treatment and who are H. pylori positive on serologic testing, were randomly assigned to either H. pylori eradication (omeprazole, amoxicillin, and clarithromycin) or placebo. Primary endpoint was the presence of endoscopic gastric or duodenal ulcers 3 months after randomization. RESULTS: One hundred sixty-five (48%) of a total of 347 patients were on gastroprotective medication. At endoscopy, gastroduodenal ulcers were diagnosed in 6 (4%) and 8 (5%) patients in the eradication and placebo group, respectively (p = .65). During follow-up of 12 months, no symptomatic ulcers or ulcer complications developed. No significant differences were found in the development of gastroduodenal erosions, dyspepsia, or in quality of life. CONCLUSION: H. pylori eradication therapy in patients on long-term NSAID treatment had no beneficial effect on the occurrence of ulcers, erosions, or dyspepsia. Ulcer rates in both study arms are remarkably low, in both patients with and without gastroprotective therapy. 相似文献

OBJECTIVE--To assess the cost effectiveness of screening for and eradicating Helicobacter pylori in patients under 45 years of age presenting with dyspepsia. DESIGN--A decision analytic model composed of a decision tree to represent the epidemiology of dyspepsia and a Markov process to model the outcomes of treatment. PATIENTS--Patients under the age of 45 years presenting to their general practitioner with (peptic type) dyspepsia. INTERVENTIONS--Conventional empirical treatment with healing and maintenance doses of cimetidine v eradication treatment solely in patients with confirmed peptic ulcer; and conventional empirical treatment for all dyspeptic patients compared with the use of a serology test to identify patients with H pylori, who then receive endoscopy to investigate the presence of peptic ulcer disease and, when disease is found, are given eradication treatment with a breath test to confirm successful eradication. MAIN OUTCOME MEASURES--Expected cumulative costs over a period of 10 years. The proportion of time patients spend without a recurrent ulcer. RESULTS--After receiving eradication treatment, patients with confirmed ulcer spend an average of 99% of their time free from recurrent ulcer disease compared with 95% after treatment with cimetidine. Eradication treatment costs less than that with cimetidine. When the initial cost of identifying appropriate patients to receive eradication treatment is added to the analysis, however, these cost savings take almost eight years to accrue. CONCLUSIONS--Enthusiasm for introducing testing for and eradication of H pylori for dyspeptic patients in general practice should be tempered by an awareness that cost savings may take many years to realise. 相似文献
