Pseudomembranous enterocolitis
MeSH D004761

In gastroenterology, 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] The disorder is an increasing matter of concern, as it is one of the more common nosocomial infections, but is also being seen in community-acquired cases.

Epidemiology

About 50% of patients with diarrhea after antibiotics that is severe enough to be admitted to the hospital have pseudomembranes on colonoscopy.[2]

Diagnosis

Clinical practice guidelines address diagnosis.[3]

Sigmoidoscopy has a sensitivity of 31% in detecting pseudomembranes as compared to colonosopy.[4]

Treatment

Clinical practice guidelines are available to direct management.[3]

Antibiotics

Various antibiotics have been studied in randomized controlled trials.[5][6][7] Teicoplanin may be the most effective antibiotic.[5][6] Vancomycin has an insignificant trend towards being better than metronidazole;[5] metronidazole is likely to be the least expensive of the group and is not a last resort for other highly resistant organisms.

"Our findings suggest that metronidazole and vancomycin are equally effective for the treatment of mild CDAD, but vancomycin is superior for treating patients with severe CDAD." according to a randomized controlled trial. [8]

Consider vancomycin if the patient has two or more points from the following:[9]

  • 1 point for each of
    • WBC > 15k
    • albumin < 2.5
    • age > 60
    • temperature > 38.3° C
  • 2 points for each of
    • Pseudomembranous colitis
    • Intensive care

It should be noted that vancomycin is given orally in this condition, and is not absorbed systemically. While it still needs to be used with care to avoid the development of resistant organisms, the risk may be lower than if it is used as a parenteral therapy for already resistant pathogens such as methicillin-resistant Staphylococcus aureus.

In a randomized controlled trial, the relative risk ratio of fidaxomicin, as compared to vancomycin, for recurrence of C. difficile infection was 0.6 and the relative risk reduction was 40.0%. In populations similar to those in this study which had a rate of risk as measured by the recurrence of C. difficile infection of 25% without treatment, the number needed to treat is 10. [10]

A case serioes suggests tigecycline for severe disease.[11]

Administration of bacteria

Probiotic administration may[12] or may not [13]help according to a meta-analyses and a more recent randomized controlled trial.[14] However, probiotics can be harmful among intensive care patients.[15]

Monoclonal antibodies

In a randomized controlled trial, the relative risk ratio of adjunct treatment with monoclonal antibodies against C. difficile toxins, as compared to placebo, for recurrence of C. difficile infection was 0.3 and the relative risk reduction was 72.0%. In populations similar to those in this study which had a rate of risk as measured by the recurrence of C. difficile infection of 25% without treatment, the number needed to treat is 6. [16]

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.[17] Use of antacids may also be a risk factor for recurrence.[18]

Asymptomatic carriage should not be treated according to a meta-analysis.[19]

Antibiotics

Randomized controlled trials of interventions for Clostridium difficile-associated diarrhea[10][8]
Trial Patients Intervention Comparison Outcome Results - cure Results - recurrence
Intervention Control Intervention Control
Louie et al[10]
2011		 629 patients
• mild to severe		 Fidaxomicin
• 200 mg twice daily
• 10 days		 Vancomycin
• 125 mg 4 times/day
• 10 days		 stool toxin after 4 weeks 88% 86% 15% 25%
Zar et al[8]
2007		 150 patients
• mild to severe		 Metronidazole
• 250 mg 4 times/day
• 10 days		 Vancomycin
• 125 mg 4 times/ day
• 10 days		 stool toxin after 3 weeks 90% 98% 15% 14%


Observational studies conflict regarding the best agent and suggest vancomycin may[20] or may not[21] be better than metronidazole. Various methods exist for the administration of vancomycin[20][22] and metronidazole[23].

Cohort studies and case series of the treatment of Clostridium difficile associated diarrhea
  Patients Intervention / duration Comparison Outcome:
Recurrence rate
Approximately 2 weeks
Vancomycin constant dose[21] 171 patients 0.5 to 2 grams daily
10 - 14 days		 NA 40%
Metronidazole constant dose[21] 115 patients 1.0 to 1.5 grams per day
10 - 14 days		 NA 37%
Metronidazole constant dose[23] 20 patients Metronidzole 1200 mg daily
14 days		 NA 45%
Vancomycin constant dose[20] 83 patients 0.5 to 3 grams/day
10 - 16 days		 NA 54%
     high dose[20] 21 patients ≥2 grams/day
10 - 16 days		 NA      43%
     medium dose[20] 14 patients 1 - 2 grams/day
10 - 16 days		 NA      71%
     low dose[20] 48 patients < 1 grams/day
10 - 16 days		 NA      54%
Metronidazole constant dose[20] 36 patients 0.5 to 3 grams/day
10 - 16 days		 NA 42%
Approximately 3 weeks
Vancomycin tapered dose[20] 29 patients Varying doses
21.5 ± 10.0 days		 NA 31%
Vancomycin pulsed dose[20] 7 patients Varying doses
21 days		 NA 14%
More than 3 weeks
Vancomycin followed by rifaximin[24] 8 patients Vancomycin of unknown duration followed by rifaximin 400–800 mg daily for 14 days
≥ 21 days		 NA 13%
Vancomycin tapered & pulsed dose[22] 22 patients 125 mg four times daily tapered to 125 mg every third day
42 days		 NA 0%

Serial therapy with vancomycin and rifaximin has been studied in a small uncontrolled series of patients.[24]

Administration of bacteria

Probiotics may help.[25] However, probiotics can be harmful among intensive care patients.[15]

Rectal infusion of feces helped according to case reports.[26][27]
