Probiotics: a promising future in the treatment of ulcerative colitis?

Abstract

Ulcerative colitis is an idiopathic and chronic inflammatory bowel disease, characterized by inflammation of the mucosa of the colon and rectum. Clinical manifestations commonly include abdominal pain, diarrhea (with or without hematochezia), and weight loss. The pathogenesis of ulcerative colitis is multifactorial, involving a combination of genetic predispositions and lifestyle factors. High consumption of processed food, sedentary habits, alcohol intake, and stress are among the lifestyle factors implicated in disease onset and progression. Current treatment strategies focus on managing symptoms and inducing remission, however, the chronic nature of the disease, along with the adverse effects of conventional therapies, often compromises patient's quality of life. Therefore, exploring alternative therapies that can prolong remission and reduce symptom burden is important. Experimental evidence suggests that probiotics may extend remission duration in ulcerative colitis. Moreover, probiotics exhibit efficacy in amelioration clinical symptoms by reducing inflammation markers, preserving, and restoring intestinal epithelial. This review explores the advantages of the administration of probiotics in the treatment of ulcerative colitis, elucidating their mechanism of action.
