Treatment of Severe Cobblestoning in Inflammatory Bowel Disease
For severe cobblestoning in IBD, initiate oral prednisolone 40 mg daily immediately, combined with topical mesalazine as adjunctive therapy, and taper the steroid gradually over 8 weeks once remission is achieved. 1
Initial Assessment and Treatment Approach
Severe cobblestoning indicates moderate-to-severe active disease that has failed first-line aminosalicylate therapy and requires immediate corticosteroid initiation. 1
Disease activity should be confirmed by sigmoidoscopy and infection must be excluded before escalating treatment, though corticosteroid therapy should not be delayed while awaiting stool microbiology results. 2, 1
The presence of severe endoscopic findings like cobblestoning warrants hospitalization if accompanied by systemic symptoms meeting Truelove and Witts' criteria (≥6 bloody stools daily, fever, tachycardia, anemia, or elevated inflammatory markers). 2
Medical Management Algorithm
First-Line Corticosteroid Therapy
Start oral prednisolone 40 mg daily for patients with severe cobblestoning who have not responded to optimized combination therapy with oral mesalazine 2-4 g daily plus topical mesalazine 1 g daily. 1
Continue topical mesalazine as adjunctive therapy alongside systemic corticosteroids to maximize local anti-inflammatory effect. 2, 1
Taper prednisolone gradually over 8 weeks according to clinical response; more rapid reduction is associated with early relapse. 1
Hospitalization Criteria for Severe Disease
If the patient presents with severe systemic illness, admit for intensive intravenous therapy with the following approach: 2
- Intravenous fluid and electrolyte replacement to correct dehydration
- Blood transfusion to maintain hemoglobin >10 g/dL
- Subcutaneous heparin to reduce thromboembolism risk
- Nutritional support (enteral or parenteral) if malnourished
- Daily monitoring of vital signs, stool frequency and character, complete blood count, inflammatory markers (ESR or CRP), electrolytes, albumin, and liver function tests
- Daily abdominal radiography if colonic dilatation (transverse colon >5.5 cm) is detected
- Joint medical and surgical management with a colorectal surgeon
Steroid-Dependent or Refractory Disease
For patients who become steroid-dependent or fail to respond adequately to corticosteroids, initiate azathioprine 1.5-2.5 mg/kg/day or mercaptopurine 0.75-1.5 mg/kg/day as steroid-sparing agents. 1
Patients who do not respond by week 14 of corticosteroid therapy are unlikely to respond with continued dosing and should be considered for biologic therapy or surgical intervention. 3
Cyclosporine may be effective for severe, steroid-refractory colitis in the acute setting. 1
Biologic Therapy Considerations
For moderate-to-severe Crohn's disease with severe cobblestoning that has failed conventional therapy, infliximab 5 mg/kg IV at weeks 0,2, and 6, then every 8 weeks is indicated. 3
For moderate-to-severe ulcerative colitis with severe endoscopic findings refractory to conventional therapy, infliximab 5 mg/kg IV using the same induction and maintenance schedule is appropriate. 3
Adalimumab is an alternative biologic option for both Crohn's disease and ulcerative colitis in patients 6 years and older who have failed conventional therapy. 4
Critical Pitfalls to Avoid
Never delay corticosteroid initiation in patients with severe endoscopic findings like cobblestoning who have failed optimized aminosalicylate therapy. 1
Avoid long-term steroid use due to significant side effects; transition to steroid-sparing agents (azathioprine, mercaptopurine) or biologics if steroid dependence develops. 1
Do not use antidiarrheal medications as they can mask worsening symptoms while allowing underlying inflammation to progress. 1
Ensure adequate dosing of mesalazine (at least 2 g daily for active disease) before declaring treatment failure. 1
Maintain close liaison with a colorectal surgeon who specializes in IBD management, as 25-30% of patients with severe disease may require colectomy. 2
