Abstract
INTRODUCTION: Currently, gastroesophageal reflux disease (GERD) is one of the most ubiquitous problems in clinical practice. An antacid-alginate combination (under the trade name Gaviscon) is a natural-based product that effectively suppresses GERD. This product acts via the formation of viscous gel that floats on the top of the gastric content. On the other hand, efficient management of Helicobacter pylori infection with minimal side effects is an important goal for gastroenterologists. Furthermore, some H. pylori-positive patients suffer from GERD. METHODS: Here, we present the results of investigations on alginate conjugated to sugar codes in order to find initial clues regarding the potential ability of this conjugate in the simultaneous prophylaxis of GERD and H. pylori infection in an in vitro assay. RESULTS: It is noteworthy that our results reveal that sugar codes conjugated alginate considerably decrease (approximately 74%) the adhesion of H. pylori to gastric epithelial cells in vitro. Moreover, surprisingly after conjugation of sugar codes, alginate can maintain its ability to create gel. Our results demonstrate that alginate conjugated to sugar codes is not cytotoxic. CONCLUSION: The preparation of these conjugates can be regarded as the first step to establish a new roadmap for the simultaneous prevention of GERD and H. pylori infection in future studies on in vivo models.
