    Study Notes

    Ulcerative Colitis

    • Hallmark sign of ulcerative colitis is bloody diarrhea
    • Other symptoms include:
      • Abdominal cramping
      • Fecal urgency
      • Tenesmus
    • Extra-intestinal symptoms:
      • Arthralgias
      • Arthritis
      • Iritis or uveitis
      • Aphthous skin lesions
      • Gallstones
    • On physical exam:
      • Check orthostatic blood pressure, pulse, and nutritional state
      • Identify signs of dehydration
      • Perform abdominal and rectal exam
    • For diagnosis:
      • Obtain complete blood count (CBC), serum albumin, and inflammatory markers
        • Erythrocyte sedimentation rate
        • C-reactive protein
      • Perform sigmoidoscopy
        • Edematous mucosa with mucopus and erosions
        • Deep ulceration and spontaneous bleeding
      • Do not perform colonoscopy during severe disease due to risk of perforation
      • Perform colonoscopy after treatment and improvement to determine extent of disease
      • Exact mechanism and cause of inflammation unknown.
    • Location of inflammation:
      • Begins in the rectum and moves backwards to the sigmoid colon in a continuous fashion (subtotal colitis)
      • Inflammation can extend beyond the rectum and sigmoid colon to include the entire colon (total colitis)
    • Treatment goals:
      • Alleviate acute symptoms
      • Prevent recurrence
    • Treatment options:
      • Aminosalicylic acid (5-ASA)
      • Corticosteroids
      • Immunomodulating drugs
      • Biologic therapies
      • Janus kinase inhibitors

    Crohn's Disease

    • Crohn's disease affects the entire intestinal wall (transmural inflammation)
    • Location of inflammation:
      • Can occur anywhere from the mouth to the anus
      • Inflammation occurs in a discontinuous and skip lesion pattern—gaps between inflamed areas are normal
      • Most common area inflamed is the terminal ileum of the small intestine
      • Second most common area is the large intestine
    • Inflammation involves macrophages and neutrophils attacking the intestinal wall causing damage. This results in transmural inflammation
    • T-cell lymphocytes infiltrate.
    • Transmural inflammation forms non-caseating granuloma (indicative of chronic inflammation)
    • Exact mechanism and cause of inflammation unknown.

    Complications of IBD

    • Crypt abscesses:
      • Epithelium of the crypt breaks down and the lumen fills with polymorphonuclear cells
      • Can lead to mild fever
      • Abscesses can rupture leading to peritonitis.
      • Treatment for abscesses
        • Intravenous antibiotic therapy
      • Drainage to prevent rupture
    • Fistula formation:
      • Worsening inflammation causes tunneling between two structures with the lumen of one section of bowel in communication with another section of bowel.
      • Location can be anywhere a lesion is adjacent to an area (e.g., fistula between a segment of bowel and the bladder).
      • Associated with pain and severe infection
      • Usually requires surgical intervention
    • Obstruction
    • Malabsorption of vitamins A, D, B12
      • Occurs when a patient has had multiple surgical procedures
    • Colon cancer

    Gastric Ulcer

    • Commonly located in the antral region of the stomach
    • Increased permeability to hydrogen ions in the stomach mucosa
    • Increased amount of acid
    • H. pylori infection directly affects mucosa
    • Symptoms:
      • GI bleeding
      • GI discomfort
      • Pain that increases after a meal
    • Long-standing inflammation can lead to stomach cancer
    • Monitoring:
      • Serial esophagogastroduodenoscopies (EGD) and biopsy
    • Gastric ulcers that progress to gastric cancer may be asymptomatic.
    • Monitoring is important for this reason.
    • Symptoms of gastric cancer may be non-specific.
    • Once symptoms are present, gastric cancer is often advanced and incurable.
    • Symptoms of gastric cancer:
      • Weight loss
      • Abdominal pain
      • Dysphagia
      • Indigestion
      • Heartburn
      • Anemia
      • Hematemesis

    Inflammatory Bowel Disease (IBD)

    • Chronic and relapsing
    • Origin is unknown but is associated with:
      • Genetics
      • Alterations of the epithelial barrier functions
      • Immune reactions to the intestinal flora
      • Abnormal T-cell responses
    • Genetic predisposition seems to be triggered by unknown mechanisms.
      • Possibly related to infections with:
        • Campylobacter
        • Salmonella
    • Seems to be a combination of both genetic predisposition and environmental factors.
    • This combination leads to the immune system attacking the GI tract.
    • Common IBD diseases:
      • Ulcerative Colitis
      • Crohn's Disease
    • Symptoms and risk factors overlap

    Risk factors for Ulcerative Colitis and Crohn's Disease

      • Especially someone with an immediate family member with the disease
    • History of smoking:
      • Especially in Crohn's Disease
    • High fat diet:

    Inflammatory Bowel Disease (IBD)

    • Chronic and relapsing inflammatory condition with an unknown origin
    • Associated with genetics, epithelial barrier dysfunction, immune response to intestinal flora, and abnormal T-cell responses
    • There is a predisposition for developing IBD, possibly triggered by infections like Campylobacter or Salmonella in the large and/or small intestine.
    • Result of a combination of genetic predisposition and environmental factors that lead to the immune system attacking the GI tract.

    • Patients classified as mild, moderate, or severe based on disease severity
    • Symptoms include bloody diarrhea, abdominal cramping, fecal urgency, and tenesmus
    • May have extra-intestinal symptoms like arthralgias, arthritis, iritis or uveitis, aphthous skin lesions, or gallstones

    Diagnosing Ulcerative Colitis

    • History: Ask about frequency of stools and presence of rectal bleeding.
    • Physical Exam: Assess volume status (orthostatic blood pressure, pulse, and nutritional state), signs of dehydration, abdominal tenderness, and rectal bleeding.
    • Laboratory Tests: Complete blood count (CBC), serum albumin, and inflammatory markers (erythrocyte sedimentation rate and C-reactive protein).
    • Sigmoidoscopy: Key diagnostic tool. Mucosa will appear edematous with mucopus and erosions. In severe cases, deep ulceration and spontaneous bleeding may be present.
    • Colonoscopy: Performed after treatment and improvement to determine the extent of the disease. Not recommended in severe cases due to the risk of perforation.

    Treatment

    • Goal: Alleviate acute symptoms and prevent reoccurrence.
    • Pharmacological Management:
      • Aminosalicylic acid (5-ASA)
      • Corticosteroids
      • Immunomodulating drugs
      • Biologic therapies
      • Janus kinase inhibitors

    Ulcerative Colitis vs. Crohn's Disease

    • Location of Inflammation:
      • Ulcerative Colitis: Begins in the rectum and moves backward to the sigmoid colon, extending continuously (subtotal colitis). Can involve the entire colon (total colitis).
      • Crohn's Disease: Occurs anywhere from the mouth to the anus in a discontinuous, skip lesion pattern with normal gaps between inflamed areas. Most common area: terminal ileum of the small intestine; second most common area: large intestine.

    Pathology

    • Ulcerative Colitis: Inflammation limited to the mucosal layer of the colon.
    • Crohn's Disease: Transmural inflammation (all three layers of the intestinal wall), resulting in non-caseating granuloma formation.

    Complications

    • Crypt Abscesses: Epithelium of the crypt breaks down, lumen fills with polymorphonuclear cells, may cause mild fever. Rupture can lead to peritonitis.
    • Fistula Formation: Tunneling between two structures, communication between bowel segments. Can occur anywhere a lesion is adjacent to another area (e.g., bowel-bladder fistula). Associated with pain and severe infection, often requiring surgical intervention.
    • Obstruction:
    • Malabsorption: Vitamins A, D, B12, especially with multiple surgical procedures.
    • Colon Cancer:

    Gastric Ulcer

    • Location: Antral region of the stomach.
    • Increased Permeability to Hydrogen Ions: Leads to increased acid levels.
    • H. pylori Infection: Direct effects on the gastric mucosa.

    • Complications: Long-standing inflammation can lead to stomach cancer.
    • Monitoring: Serial esophagogastroduodenoscopies (EGD) and biopsies.
