Participant gender:
All
Summary
This is a randomized, double-blind, placebo-controlled trial to determine the optimal dose and safety of oral alanyl-glutamine between 4, 24, and 44 g doses administered for 10 days with standard therapy among first time incident cases of uncomplicated C. difficile infection (CDI) in hospitalized persons aged 65 or older. Our hypothesis is that alanyl-glutamine supplementation will decrease recurrence and mortality from CDI and these outcomes will be associated with improvement of inflammatory markers and restoration of intestinal microbiota function.
