From the Guidelines

For the treatment of sterocolitis with antibiotic treatment, the most effective approach is to use vancomycin 125mg four times daily for 10-14 days, as recommended by the Infectious Diseases Society of America (IDSA) and Society for Healthcare Epidemiology of America (SHEA) 1.

Treatment Approach

The treatment of sterocolitis, particularly when caused by Clostridioides difficile, involves a targeted approach to eliminate the pathogenic bacteria while preserving the beneficial gut flora.

  • The use of vancomycin is preferred over metronidazole due to its higher efficacy in treating C. difficile infections, as shown in a study published in 2018 1.
  • The recommended dosage of vancomycin is 125mg four times daily for 10-14 days, which has been shown to be effective in treating initial and recurrent C. difficile infections.
  • For severe cases, combination therapy with vancomycin and metronidazole may be necessary, but this should be done with caution due to the potential for cumulative neurotoxicity associated with metronidazole.

Supportive Care

In addition to antibiotic treatment, supportive care is essential to manage the symptoms of sterocolitis and prevent complications.

  • Fluid replacement and electrolyte correction are crucial to prevent dehydration and electrolyte imbalances.
  • Probiotics, such as Saccharomyces boulardii or Lactobacillus species, can help restore the normal gut flora and prevent recurrent infections.
  • Patients should maintain adequate hydration, follow a bland diet during acute phases, and report worsening symptoms like severe abdominal pain, high fever, or significant bloody diarrhea immediately.

Recurrent Cases

For recurrent cases of sterocolitis, extended antibiotic tapers or fecal microbiota transplantation (FMT) may be considered.

  • FMT has been shown to be effective in treating recurrent C. difficile infections, with a success rate of up to 90% in some studies 1.
  • However, FMT should only be considered for patients who have failed to respond to antibiotic treatment and have undergone careful evaluation and selection of a suitable stool donor.

Conclusion is not allowed, so the answer will continue without one.

It is essential to note that the treatment of sterocolitis should be individualized based on the severity of the infection, the patient's underlying medical conditions, and the presence of any complications.

  • The use of antibiotics should be guided by the results of stool tests and susceptibility profiles to ensure that the most effective treatment is used.
  • Patients should be closely monitored for signs of clinical deterioration and treated promptly if complications arise.
  • The treatment of sterocolitis requires a comprehensive approach that includes antibiotic treatment, supportive care, and prevention of recurrent infections.

From the FDA Drug Label

Vancomycin Hydrochloride Capsules are indicated for the treatment of C. difficile-associated diarrhea. Vancomycin Hydrochloride Capsules are also used for the treatment of enterocolitis caused by Staphylococcus aureus (including methicillin-resistant strains) in adult and pediatric patients less than 18 years of age

The treatment for sterocolitis (also known as enterocolitis) with antibiotic (abx) treatment using vancomycin is supported by the FDA drug label. The recommended dose for staphylococcal enterocolitis is a total daily dosage of 500 mg to 2 g administered orally in 3 or 4 divided doses for 7 to 10 days 2.

From the Research

Treatment of Sterocolitis with Antibiotics

  • The treatment of pseudomembranous colitis, a form of sterocolitis, typically involves the use of antibiotics such as metronidazole or vancomycin 3, 4.
  • Metronidazole is often recommended as the first-line therapy, with vancomycin reserved for severe cases or those who do not respond to metronidazole 3, 4.
  • In cases of severe C. difficile colitis, intracolonic vancomycin enemas have been shown to be effective in achieving complete resolution without surgery in approximately 70% of patients 5.
  • Vancomycin has been found to be effective in treating pseudomembranous colitis, with rapid clinical cure expected when given orally in a dose of 125 mg every 6 h 6.

Management of Severe and Fulminant Infection

  • Severe C. difficile infection can pose a significant morbidity and mortality risk and is considered a medical emergency 7.
  • International guidance on the management of C. difficile infection varies, but vancomycin and fidaxomicin are now recommended as first-line options, with metronidazole no longer favored due to concerns around resistance 7.
  • Antibiotic therapy should be used in conjunction with good supportive measures and early consideration of surgical management, with faecal microbiota transplant potentially useful in recurrent or severe disease 7.

Recurrent Infection

  • Recurrent C. difficile disease is a significant clinical problem, with approximately 20% of cases experiencing recurrence 3.
  • Treatment of recurrent disease often involves a combination of antibiotics and biotherapeutic agents, such as the non-pathogenic yeast Saccharomyces boulardii 4.
  • Faecal microbiota transplant may also be useful in preventing further recurrences of C. difficile infection 7.
