The treatment options for Clostridium difficile infection remain limited,
although promising agents are currently being assessed. Metronidazole is
the first-line drug of choice for those patients requiring specific anti-C.
difficile treatment. Much of the interest in alternative therapies has
centred on the difficult management issues posed by patients with multiple
symptomatic recurrences of C. difficile infection. However, it is now clear
that the majority of these episodes are due to reinfections with new C.
difficile strains and not relapses caused by the original bacterium. Hence,
the true efficacy of the alternative regimens remains unclear. Individuals
susceptible to C. difficile reinfections need to be protected from exposure
to C. difficile until their bowel flora recovers. While several
biotherapeutic approaches to the treatment and prevention of C. difficile
infection have been described, few controlled data are available.
Preliminary studies with anti-C. difficile bovine immunoglobulin
concentrates for treatment and prevention have produced promising results.
Vaccination to prevent C. difficile infection, particularly in high-risk
elderly patients managed within institutions where C. difficile is endemic,
is a worthwhile therapeutic goal.
