Antibiotic-induced diarrhea and pseudomembranous colitis
1DeKalb Medical Specialty Center, Decatur, Georgia.
Abstract:
Pseudomembranous colitis is commonly associated with the use of antibiotics but may follow administration of other drugs and has occurred in patients who have not received any medication. Cases related to antibiotic administration are thought to be due to changes in normal intestinal flora that allow overgrowth of Clostridium difficile and elaboration of toxin. Clusters of cases in hospitals suggest nosocomial transmission of the bacteria. The stool cytotoxin assay is the most specific test for pseudomembranous colitis. Oral vancomycin (Vancocin) is preferred for the treatment of severe cases. It is recommended that hospital personnel caring for patients infected with C difficile wear gloves and wash their hands carefully after contact.
Insights
Pseudomembranous colitis, often caused by antibiotics, results from Clostridium difficile overgrowth. Early diagnosis via stool cytotoxin assay and treatment with oral vancomycin for severe cases are crucial for patient recovery.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Microbiology
Background:
- Pseudomembranous colitis is frequently linked to antibiotic use, altering gut flora and enabling Clostridium difficile proliferation.
- This condition can also arise from other medications or in patients without prior drug exposure.
- Hospital-acquired clusters suggest Clostridium difficile can transmit between patients.
Purpose of the Study:
- To summarize the understanding of pseudomembranous colitis etiology, diagnosis, and management.
- To highlight the role of Clostridium difficile and its toxins in disease pathogenesis.
- To provide recommendations for infection control in healthcare settings.
Main Methods:
- Review of existing literature on pseudomembranous colitis.
- Analysis of diagnostic methods, focusing on the stool cytotoxin assay.
- Evaluation of treatment strategies, including oral vancomycin for severe infections.
Main Results:
- The stool cytotoxin assay is identified as the most specific diagnostic test.
- Oral vancomycin is the preferred treatment for severe cases of pseudomembranous colitis.
- Nosocomial transmission of Clostridium difficile is a significant concern.
Conclusions:
- Effective management involves accurate diagnosis and appropriate antimicrobial therapy.
- Strict adherence to infection control measures, including hand hygiene and glove use, is essential to prevent Clostridium difficile spread.
