In this pilot study we decided to test our modification of sucrose permeability test (SaLM test) on upper dyspepsia patients in our conditions. We first needed to compare the results of intestinal permeability obtained from the studied test (containing sucrose, a so called SaLM test) with a formerly established intestinal permeability test (containing glucose, a so called LaMa test) to know, if the new test could replace the old one.
Then we wanted to find normal values of sucrose permeability, find a relationship between sucrose permeability and endoscopically verified damage to upper gastrointestinal mucosa and calculate sensitivity and specificity of SaLM test using results of gastroduodenoscopy. Conclusion: SaLM test could replace LaMa test without having a significant effect on the intestinal permeability results.
It is feasible to study SaLM test on bigger sets of patients and specify it in more detail, since the results of our pilot study (in accordance with many other studies) make it promisin
