Clostridium difficile: Changing Epidemiology, Treatment and Infection Prevention Measures.
Clostridium difficile was first reported as a cause of antibiotic-associated colitis in 1978. In more recent years we have witnessed disturbing trends associated with C. difficile infection (CDI). CDI has become more common, affecting populations previously considered at low risk, more severe with an associated increase in mortality, and more difficult to treat with some patients experiencing multiple relapses and a reduced responsiveness to previously effective antibiotics. These trends have been coincident with the emergence of a new hypervirulent strain responsible for several outbreaks in the last decade. Fortunately, we have also seen promising developments, particularly with regard to testing and treatment. This review discusses recent changes in the epidemiology of CDI and recent developments in the testing, treatment and prevention of CDI.
