 Pseudomembranous enterocolitis | |
| MeSH | D004761 |
In medicine, pseudomembranous enterocolitis is an "acute inflammation of the intestinal mucosa that is characterized by the presence of pseudomembranes or plaques in the small intestine (pseudomembranous enteritis) and the large intestine (pseudomembranous colitis). It is commonly associated with antibiotic therapy and clostridium difficile colonization."[1]
Diagnosis
The accuracy of laboratory tests is:[2]
| Sensitivity | Specificity | |
|---|---|---|
| Cytotoxin by enzyme immunoassay | 73% | 97% |
| Cell culture cytotoxin assay (tissue culture assay) |
77% | 97% |
| Real-time polymerase chain reaction | 93% | 97% |
| Anaerobic culture (for toxigenic C. difficile strains) |
100% | 96% |
Treatment
Antibiotics
Various antibiotics have been studied in randomized controlled trials.[3][4][5] Teicoplanin may be the most effective antibiotic.[3][4] Vancomycin has an insignificant trend towards being better than metronidazole.[3]
Administration of bacteria
Probiotic administration may[6] or may not [7]help according to a meta-analyses and a more recent randomized controlled trial.[8] However, probiotics can be harmful among intensive care patients.[9]
Recurrent infection
A clinical prediction rule found that recurrent infection is more likely if age is more than 65 years, the patient has severe or fulminant illness, and additional antibiotic exposure occurs after after treatment of the initial Clostridium difficile infection.[10] Use of antacids may also be a risk factor for recurrence.[11]
Asymptomatic carriage should not be treated according to a meta-analysis.[12]
Antibiotics
Observational studies conflict regarding the best agent and suggest vancomycin may[13] or may not[14] be better than metronidazole. Various methods exist for the administration of vancomycin[13]
Serial therapy with vancomycin and rifaximin has been studied in a small uncontrolled series of patients.[15]
Administration of bacteria
Probiotics may help.[16] However, probiotics can be harmful among intensive care patients.[9]
Rectal infusion of feces helped according to case reports.[17][18]
