title: The safety of whey protein concentrate derived from the milk of cows immunized against Clostridium difficile.
abstract: A whey protein concentrate prepared from the milk of cows that have been immunized against Clostridium difficile (C. difficile) and its toxins, toxin A and toxin B, is produced for use as a medical food for the dietary management of patients with C. difficile-associated diarrhea (CDAD) to prevent a relapse of the infection. The safety of anti-C. difficile whey protein concentrate (anti-CD WPC) is supported by analytical data comparing the composition of raw milk from immunized cows versus that from non-immunized cows, and the composition of anti-CD WPC versus that of regular whey protein concentrate. Additionally, a prospective clinical study was conducted in 77 patients with CDAD to demonstrate the safety of consuming anti-CD WPC to prevent relapse of the infection. This study, which included adverse event monitoring, physical examinations, and extensive hematological and biochemical assessments, showed that anti-CD WPC is safe to consume by patients with CDAD. The available analytical and clinical evidence demonstrate that anti-CD WPC is safe for use by individuals with CDAD, under the described conditions of use.
