    1. Crohn's Disease
    2. Inflammatory Bowel Disease
  2. Definitions
    1. Ulcerative Colitis
      1. Inflammatory Bowel Disease affecting the mucosa of the Large Intestine and Rectum
      2. Presents with Abdominal Pain, bloody Diarrhea, fever and weight loss
  3. Epidemiology
    1. Most common cause of chronic colitis
    2. Incidence: 2-7 cases per 100,000 per year in U.S.
    3. Prevalence: 250,000 to 500,00 persons affected in United States
      1. More common in industrialized countries
    4. Onset
      1. First peak onset at age 15 to 25 years (up to age 40 years)
      2. Second peak onset occurs after age 50 years
    5. Gender
      1. Men and women affected equally

  18. Management: Approach
    1. Mild to moderate distal colitis
      1. When remission occurs with any step, transition to maintenance dosing of current agent
      2. Step 1: Topical 5-ASA at active dose per Rectum for 4-6 weeks
        1. Suppository for isolated Proctitis
        2. Enema for more proximal, left-sided Ulcerative Colitis
      3. Step 2: Consider ADDing shortterm rectal Corticosteroids
        1. Hydrocortisone enema (Cortenema) or if enema not retained, then foam (Cortifoam, Uceris)
      4. Step 3: ADD oral 5-ASA at active dose for 4-6 weeks (while continuing rectal 5-ASA)
      5. Step 4: Go to step 2 under mild-moderate extensive colitis
    2. Mild to moderate extensive colitis
      1. Step 1: Oral 5-ASA at active dose for 4-6 weeks
        1. If remission occurs, continue oral 5-ASA at maintenance dosing
      2. Step 2: Oral Corticosteroids for 4-6 weeks
        1. If remission occurs, transition to biologic agents (see below) at maintenance dosing
      3. Step 3: Biologic Agents (see below)
        1. If remission occurs, continue biologic agent (see below) at maintenance dosing
    3. Severe to fulminant colitis
      1. Hospital admission (up to 25% of Ulcerative Colitis acute presentations)
      2. Step 1: Corticosteroids IV at active dose for 3-5 days
        1. If remission occurs, transition to biologic agents at maintenance dosing
      3. Step 2: Biologic agents are considered first-line therapy
        1. Consider Cyclosporine or Infliximab for failed response to Corticosteroids
      4. Step 3: Consider surgical intervention

    2. Duration of medication use: 6-12 weeks
      1. Taper preparations to prevent rebound
    3. Route
      1. Rectal suppositories are preferred for Proctitis
      2. Use oral and rectal agents together for pancolitis
      3. Combined oral and rectal agents are more effective than either one alone
  20. Management: Corticosteroids for Moderate to Severe disease
    1. Precaution
      1. Use only to stabilize active Ulcerative Colitis
      2. Avoid chronic use as these do not maintain remission and have serious longterm adverse effects
    2. Corticosteroids: Systemic
      1. Agents
        1. Prednisone 40-60 mg/day orally until improving, then decrease daily dose by 5-10 mg each week
        2. Methylprednisolone (Medrol) 40-60 mg/day orally
        3. Hydrocortisone (Cortef) 200-300 mg/day orally
        4. Methylprednisolone (Solu-Medrol) 40 mg IV daily
      2. Taper Corticosteroids gradually to prevent rebound
        1. Continue starting dose until clinical response (typically 10-14 days)
        2. After response, reduce dose by 5mg per week
      3. Efficacy
        1. Systemic Corticosteroids do not maintain remission and have serious side effects
    3. Coticosteroids: Uceris (extended release Budesonide)
      1. Uceris (extended release Budesonide) 9 mg orally daily for up to 8 weeks
      2. Uceris cost is an oral budesonide tablet that primarily works locally in colon
      3. Contrast with Entocort EC that targets ileum and ascending colon in Crohn's Disease
      4. Contrast with Systemic Corticosteroids with their multitude of adverse effects
        1. Uceris Systemic Corticosteroid effects are increased with CYP3A4 Inhibitors

Ulcerative Colitis (C0009324)

Definition (MEDLINEPLUS)

Ulcerative colitis (UC) is a disease that causes inflammation and sores, called ulcers, in the lining of the rectum and colon. It is one of a group of diseases called inflammatory bowel disease.

UC can happen at any age, but it usually starts between the ages of 15 and 30. It tends to run in families. The most common symptoms are pain in the abdomen and blood or pus in diarrhea. Other symptoms may include

  • Anemia
  • Severe tiredness
  • Weight loss
  • Loss of appetite
  • Bleeding from the rectum
  • Sores on the skin
  • Joint pain
  • Growth failure in children

About half of people with UC have mild symptoms.

Doctors use blood tests, stool tests, colonoscopy or sigmoidoscopy, and imaging tests to diagnose UC. Several types of drugs can help control it. Some people have long periods of remission, when they are free of symptoms. In severe cases, doctors must remove the colon.
