Sucralfate therapy in patients with symptoms of alkaline reflux gastritis. A randomized, double-blind study.

The effects of sucralfate (6 g per day) and placebo on symptoms, endoscopic findings, and gastric mucosal histology were compared in 23 patients with symptoms of alkaline reflux gastritis who had undergone Billroth I, Billroth II, or vagotomy and pyloroplasty. Patients were randomly assigned to receive sucralfate (n = 11) or placebo (n = 12) for six weeks. Then all received six weeks of open sucralfate therapy before treatment codes were revealed. Twelve gastric biopsy specimens were obtained before patients began treatment and at six and 12 weeks. The two groups did not differ significantly with respect to symptom scores or endoscopic findings at baseline, after the double-blind phase, or after open sucralfate treatment. There were also no significant differences between the treatment groups with respect to epithelial cell scores and conventional gastritis scores. However, after the six-week, double-blind phase, the inflammatory cell score of the sucralfate-treated group was significantly lower (p less than 0.05) than that of the placebo-treated group (1.3 +/- 0.3 versus 1.9 +/- 0.4). After six weeks of open sucralfate treatment, patients who had initially received placebo had a significant reduction (1.4 +/- 0.3 versus 1.9 +/- 0.4) in their inflammatory cell score. Sucralfate lowered the inflammatory cell scores of patients with symptoms of alkaline reflux gastritis. This reduction, however, was not associated with an improvement in symptoms.
