Management of Severe Acute Ulcerative Colitis with Toxic Colitis
The best management plan for a patient with severe acute ulcerative colitis with toxic colitis is IV steroids and infliximab (option B). 1
Initial Assessment and Classification
- This 50-year-old patient with a 10-year history of ulcerative colitis presents with classic features of severe acute ulcerative colitis (ASUC): >8 bloody stools per day, abdominal pain, tenderness, fever, anemia, leukocytosis, hypoalbuminemia, and elevated inflammatory markers (ESR and CRP) 1
- The presentation with toxic colitis represents a potentially life-threatening condition requiring immediate hospitalization and intensive management 1, 2
- Initial workup should include blood tests (CBC, CRP, electrolytes, liver function), stool cultures, C. difficile testing, and flexible sigmoidoscopy to confirm diagnosis and exclude cytomegalovirus infection 1, 2
First-Line Treatment
- Intravenous corticosteroids remain the cornerstone of initial management for ASUC 1
- The recommended regimen is either methylprednisolone 60mg daily or hydrocortisone 100mg four times daily 1
- Higher doses of corticosteroids do not offer additional benefit and may increase adverse effects 1
- Response to IV corticosteroids should be assessed after 3-5 days of therapy 1
Rescue Therapy for Steroid-Refractory Disease
- Approximately one-third of patients with ASUC will not respond adequately to IV corticosteroids 1, 3
- For patients who fail to respond to IV steroids after 3-5 days, rescue therapy with either infliximab or cyclosporine should be initiated 1
- Given the patient's presentation with toxic colitis and severe symptoms, early consideration of rescue therapy with infliximab is warranted 1
- Infliximab is FDA-approved for reducing signs and symptoms, inducing and maintaining clinical remission, and eliminating corticosteroid use in patients with moderately to severely active ulcerative colitis 4
Why IV Steroids + Infliximab is Superior to Other Options
- IV steroids plus infliximab has shown superior efficacy compared to IV steroids alone in steroid-refractory ASUC 1
- The combination of IV steroids and rectal steroids (option A) would be insufficient for toxic colitis, which requires systemic therapy and consideration of early rescue therapy 1
- Cyclosporine (option C) is an alternative rescue therapy, but infliximab may be preferred due to its established long-term maintenance potential 1, 3
- Surgical resection (option D) should be reserved for patients who fail medical therapy or develop complications such as perforation, toxic megacolon, or massive bleeding 1, 5
Supportive Measures
- Thromboprophylaxis with low-molecular-weight heparin is essential as patients with ASUC have increased risk of thromboembolism 1, 2
- Fluid and electrolyte replacement to correct dehydration and electrolyte imbalances 1, 2
- Nutritional support if the patient is malnourished 1, 2
- Blood transfusion to maintain hemoglobin >10 g/dL 1, 2
Monitoring Response and Decision-Making
- Close monitoring of vital signs, stool frequency, abdominal examination, and laboratory parameters (CRP, albumin) is crucial 1, 2
- Joint management by gastroenterologists and colorectal surgeons is recommended 1
- If no improvement is seen after 3-5 days of IV steroids, infliximab should be initiated at 5 mg/kg at weeks 0,2, and 6, followed by maintenance therapy 2, 4
- Patients should be informed about a 25-30% chance of ultimately requiring colectomy despite optimal medical therapy 1, 2
