Systematic review: persistence and severity in gastro-oesophageal reflux disease Armstrong DAliment Pharmacol Ther 2008[Oct]; 28 (7): 841-53BACKGROUND: Management strategies for gastro-oesophageal reflux disease (GERD) are often inconsistent with the proposition that it is a persistent or chronic disease. AIM: To determine the persistence of reflux symptoms and complications associated with GERD. METHODS: Systematic searches of Medline and EMBASE. RESULTS: In longitudinal studies, 65% (95% CI 54-75%) of patients with complicated GERD and 70% (95% CI 57-83%) of patients with 'defined' GERD had persistent disease at follow-up, whereas 34% (95% CI 27-40%) with infrequent or mild reflux symptoms at baseline had persistent symptoms. Clinical trials of maintenance treatment for at least 6 months after healing of oesophagitis reported mean relapse rates of 75% (95% CI 68-82%) in patients taking placebo and 28% (95% CI 21-35%) in those taking proton pump inhibitors. Retrospective studies reported that 34-41% of individuals with GERD recalled experiencing their symptoms for >10 years. The prevalence of GERD is high (10-20%), whereas the incidence is low (4.5-19.6 cases per 1000 person-years), suggesting that GERD is likely to persist for at least 18 years. CONCLUSIONS: Individuals with GERD have persistent reflux symptoms that merit management as a chronic disease; infrequent reflux symptoms are less likely to be chronic and may respond to different management strategies.|*Evidence-Based Medicine[MESH]|*Gastroesophageal Reflux/drug therapy/metabolism[MESH]|Chronic Disease[MESH]|Clinical Trials as Topic[MESH]|Gastrointestinal Agents/therapeutic use[MESH]|Humans[MESH]|Incidence[MESH]|Longitudinal Studies[MESH]|Prevalence[MESH] |
