OBJECTIVES: Systemic sclerosis (SSc) is a multisystem disease characterized by abnormalities of small blood vessels, and fibrosis of the skin and internal organs including gastrointestinal tract. This article reviews the esophageal involvement in SSc, emphasizing the gastroesophageal reflux, which is a common problem in SSc patients. METHODS: We conducted a Medline search from 1966 to 2005. The keywords "systemic sclerosis," "esophageal involvement," "gastroesophageal reflux," "esophagitis," and "treatment" were used. RESULTS: The gastrointestinal tract is frequently affected in diffuse and limited disease. Although any part of the gastrointestinal tract can be involved, esophageal disease occurs in nearly all patients with SSc. Common esophageal manifestations in SSc include motility abnormalities and gastroesophageal reflux (GER), Barrett's esophagus, adenocarcinoma, infectious esophagitis, and drug-induced esophagitis. Common complications of GER include esophagitis with erosions and bleeding and stricture formation. Extraesophageal manifestations of GER include mouth ulcers, chronic cough, hoarse voice, sore throat, pharyngitis, laryngospasm, asthma, and recurrent pneumonia. Diagnostic procedures used in the investigation of esophageal involvement include barium esophagram, esophageal manometry, 24-hour ambulatory pH, and endoscopy. Treatment of GER in SSc includes behavioral modification and medical therapy, mainly with proton pump inhibitors. Surgical intervention has a limited role in the management of GER in selected SSc patients. CONCLUSIONS: Esophageal involvement is frequent in SSc patients. Gastroesophageal reflux may cause high morbidity. Careful examination of the patients reveals gastrointestinal abnormalities even in patients without symptoms. Appropriate treatment of esophageal involvement ameliorates symptoms and prevents complications.
OBJECTIVE: Gastroesophageal flap valve (GEFV) grade predicts severe gastroesophageal reflux disease in Caucasians, but its role in other populations is unclear. This study evaluated the significance of endoscopic grading of the GEFV in Taiwanese subjects. METHODS: Five hundred and six consecutive patients undergoing routine check-ups at the National Taiwan University Hospital were enrolled. Symptoms of upper gastrointestinal disease and endoscopic severity of esophageal mucosal injury were correlated to GEFV grades according to the Hill classification. RESULTS: The frequency of abnormal valves (Hill grades III or IV) was 27.3%. Of these, 42.7% had erosive esophagitis (EE). The majority of patients with EE were classified as Los Angeles grades A and B (79.7 and 16.9%, respectively). The prevalence of EE, hiatal hernia and, to a lesser degree, non-erosive reflux disease, increased with altered GEFV. Patients with abnormal valves were younger and more likely to be male, overweight, and to have atypical and extraesophageal symptoms. CONCLUSIONS: Taiwanese patients with abnormal GEFVs share similar characteristics and risk factors with the patients who have EE. Endoscopic grading of the GEFV is highly associated with GERD, and in particular EE, in subjects undergoing routine endoscopy.
AIM: To systematically evaluate the efficacy of H(2)-receptor antagonists (H(2)RAs) and proton pump inhibitors in healing erosive esophagitis (EE). METHODS: A meta-analysis was performed. A literature search was conducted in PubMed, Medline, Embase, and Cochrane databases to include randomized controlled head-to-head comparative trials evaluating the efficacy of H(2)RAs or proton pump inhibitors in healing EE. Relative risk (RR) and 95% confidence interval (CI) were calculated under a random-effects model. RESULTS: RRs of cumulative healing rates for each comparison at 8 wk were: high dose vs standard dose H(2)RAs, 1.17 (95%CI, 1.02-1.33); standard dose proton pump inhibitors vs standard dose H(2)RAs, 1.59 (95%CI, 1.44-1.75); standard dose other proton pump inhibitors vs standard dose omeprazole, 1.06 (95%CI, 0.98-1.06). Proton pump inhibitors produced consistently greater healing rates than H(2)RAs of all doses across all grades of esophagitis, including patients refractory to H(2)RAs. Healing rates achieved with standard dose omeprazole were similar to those with other proton pump inhibitors in all grades of esophagitis. CONCLUSION: H(2)RAs are less effective for treating patients with erosive esophagitis, especially in those with severe forms of esophagitis. Standard dose proton pump inhibitors are significantly more effective than H(2)RAs in healing esophagitis of all grades. Proton pump inhibitors given at the recommended dose are equally effective for healing esophagitis.
