Inflammatory Bowel Disease (IBD) is a chronic idiopathic inflammation of the gastrointestinal tract, characterized by periods of exacerbation and remission, which includes two primary forms: Ulcerative Colitis (UC) and Crohn's Disease (CD). IBD is an autoimmune disorder influenced by genetics, hereditary, environment, and infection. Alternative treatments with fewer side effects have been searched. Thus, the use of probiotics stands out due to several beneficial effects. For this reason, the objective of this systematic review is to evaluate the effects of the use of probiotics in patients diagnosed with IBD. This review included studies available in the MEDLINE databases - PubMed, EMBASE, and Cochrane, and the final selection included thirteen randomized clinical trials. The results showed that the oral use of probiotics and, mainly for a prolonged period, can help in the improvement of reducing symptoms related to IBD. In endoscopic analyzes, a reduction in intestinal inflammation was noted, in addition to a reduction in proinflammatory cytokines. Although there are positive effects, there is a need for further studies to define the best composition of probiotics and time of use since there are many variations in this treatment.
