C. Difficile Infection
James Pile, MD, and Glenn Wortmann, MD
Supported by an educational grant from Merck & Co Inc.
Clostridium difficile (C. difficile) is a Gram-positive, toxin-producing, anaerobic bacillus, which is commonly responsible for antibiotic-associated diarrhea. An estimated 500 000 cases occur each year in the United States, and the incidence and severity of disease appear to be increasing. The morbidity of C. difficile infection (CDI) has risen by as much as 25% per year, and a 20-fold increase in mortality has been reported. Human transmission is through the fecal-oral route, and CDI has become the most frequently reported hospital-acquired infection, with nosocomial acquisition more than quadrupling the cost of hospitalization. Diagnosis of patients with CDI should be made based on clinical grounds in conjunction with stool testing, with the caveat that current diagnostic strategies remain imperfect. Although effective treatment is available, approximately 20% of patients suffer relapse after an initial infection; those patients with multiple prior infections face a 60% recurrence risk. Emerging therapeutics are being developed and may revolutionize therapy. Hospitalists should be knowledgeable about the clinical presentation of CDI and therapies based on disease severity. In addition, awareness of treatment strategies for patients with recurrent infections and emerging treatment options will help practitioners manage this complex disease.
To provide hospitalists with current data and guidelines regarding the diagnosis and treatment of hospitalized patients with CDI.
This activity is designed for hospitalists and residents interested in the field of consultative medicine. No prerequisites required.
After completing the module, the participant should be able to:
• IDENTIFY risk factors associated with C. difficile infection.
• DISCUSS current options for the laboratory diagnosis of C. difficile infection, including strengths and limitations of each.
• DESCRIBE the therapeutic options for C. difficile infection, based on disease severity.
• OUTLINE the factors associated with recurrent C. difficile infection.
• IDENTIFY potential treatment strategies for recurrent C. difficile infection, including their limitations.
• DEMONSTRATE familiarity with new horizons in the prevention and treatment of C. difficile infection.
