Title: Uso de probióticos en el tratamiento del síndrome de intestino irritable
Author: Pérez Cano, María

Abstract: Irritable bowel syndrome (IBS) is a gastrointestinal disease that causes abdominal pain associated with defecation and changes in stool consistency. Although its pathophysiology remains unclear, it has been related to an alteration of the microbiota. This is why probiotics (live organisms that seek to help in the improvement of symptoms) have been developed. The aim of this study is to review recent results obtained in trials with probiotics. When considering the improvement in various representative parameters of IBS (general symptoms, abdominal pain, bloating, change in stool consistency and improvement in quality of life), a large percentage of improvement is observed, especially in abdominal pain and global symptoms. This improvement is more noticeable in single-strain probiotics, and could be due to the beneficial effect of probiotics on intestinal dysbiosis, as well as to the modulation they exert on the immune response. However, it is difficult to draw clear conclusions, since these are studies of variable duration and they use different strains and doses of microorganisms. In addition, the symptomatology of the disease is varied and the placebo effect of the studies is quite considerable. Therefore, probiotics may help to treat IBS, but more evidence is needed to establish recommendations on beneficial strains and doses, as well as to clarify the mechanisms of action by which these probiotics work.
