Brief Summary

Diverticulosis of the colon is a frequent condition in adults in western countries and a significant number of patients experience clinical symptoms even when the diverticulosis is not complicated by diverticulitis. Both central and mucosal immunity are altered in Uncomplicated Symptomatic Diverticular Disease (USDD) and Rifaximin ameliorate clinical symptoms and normalize the immunological abnormalities. The Study Protocol is verify the modifications in the immunological pattern induced by reducing bacteria related activation of immunity by Rifaximin treatment.
