A 28-year-old woman with a history of extensive ulcerative colitis is hospitalized due to a severe disease flare characterized by 12 bloody bowel movements daily, severe lower abdominal cramping, and a temperature of 38.6∘C38.6^\circ\text{C} (101.5∘F101.5^\circ\text{F}). Her heart rate is 118/min118/\text{min} and blood pressure is 110/70 mm Hg110/70 \text{ mm Hg}. Arrange the following management steps in the correct chronological sequence of escalation, assuming she remains refractory to each successive medical intervention.

  1. 1Obtain stool studies for Clostridioides difficile and enteric pathogens
  2. 2Administer high-dose intravenous methylprednisolone
  3. 3Administer biologic rescue therapy such as infliximab
  4. 4Perform a total abdominal colectomy with end ileostomy

Cevap

The correct sequence is: 1) Obtain stool studies for C. difficile, 2) Administer intravenous methylprednisolone, 3) Administer biologic rescue therapy (infliximab), 4) Perform a total abdominal colectomy.
The management of severe ulcerative colitis follows a strict escalation protocol to maximize medical salvage while preventing catastrophic surgical complications. Superimposed infections (like C. difficile) must first be ruled out. Once excluded, IV corticosteroids are the first-line treatment. If patients fail to respond after 3 to 5 days, rescue therapy with infliximab or cyclosporine is indicated. Surgery is reserved for patients refractory to all medical options.

Adım Adım Çözüm

1
Evaluate for infectious triggers.
Stool studies are ordered to rule out C. difficile and other pathogens.
Superimposed infections must be excluded prior to escalating immunosuppression, as giving high-dose steroids in the setting of active infection can lead to toxic megacolon.
2
Initiate first-line medical therapy for a severe flare.
Intravenous methylprednisolone is administered.
Systemic corticosteroids effectively reduce colonic inflammation in acute, severe ulcerative colitis.
3
Escalate to medical rescue therapy if steroids fail.
Infliximab or cyclosporine is given.
Biologic or calcineurin inhibitor rescue therapy is required for steroid-refractory disease to avoid emergent colectomy.
4
Proceed to surgical intervention if all medical options fail.
Total abdominal colectomy is performed.
Surgery is curative for ulcerative colitis and is the definitive treatment when maximal medical therapy fails or acute life-threatening complications arise.

Anahtar Kavram

Stepwise escalation in severe ulcerative colitis: rule out infection, initiate IV steroids, escalate to biologic rescue, and proceed to surgery if refractory.
