Study Notes
Inflammatory Bowel Disease
- Ulcerative Colitis (UC) and Crohn's disease are both inflammatory bowel diseases that cause periods of remission and flare-ups.
Ulcerative Colitis
- Diarrhea is the most common manifestation of UC.
- Mild UC features less than 4 stools per day, small amounts of blood, normal CRP and ESR, and mild crampy abdominal pain.
- Moderate UC involves 4-6 bloody stools per day, mild anemia, and non-severe abdominal pain with no significant systemic toxicity.
- Severe UC is characterized by more than 6 bloody stools per day, severe cramps, and evidence of systemic toxicity like fever and tachycardia.
Crohn Disease
- Crohn's disease usually features less severe diarrhea than UC, with minimal blood or mucus in the stool.
- Crohn's disease can cause cramping or steady pain in the right lower quadrant (RLQ) or periumbilical region, with tenderness and a mass noted in the RLQ.
Comparing UC and Crohn's Disease
- Both diseases affect both sexes equally and peak in individuals between 15 to 30 years old.
- UC typically involves the rectum and sigmoid colon, potentially affecting the entire large bowel.
- Crohn's disease can affect any part of the GI tract, with the terminal ileum and ascending colon frequently involved.
- UC features a continuous distribution pattern in the bowel, while Crohn's disease presents with patchy, discontinuous patches of damage known as "skip lesions."
- UC involves lesions in the mucosa, while Crohn's disease affects the entire bowel wall (transmural).
- UC presents with a granular, dull, hyperemic, and friable mucosa, often with pseudopolyps. Crohn's disease exhibits a "cobblestone" appearance, with alternating areas of ulceration and fissures.
- Complications of UC include toxic megacolon, perforation, and massive hemorrhage.
- Crohn's disease can lead to obstruction, fistulization, abscess formation, and malabsorption.
Ulcerative Colitis and Crohn's Disease
- While both Ulcerative Colitis (UC) and Crohn's Disease (CD) have similar clinical presentations, there are differences in how they manifest.
- Both UC and CD share similar clinical features including periods of symptom-free remissions and sporadic periods of active disease (flare-ups).
- UC and CD manifest differently across several characteristics:
- Sex: Both UC and CD are equally common in males and females.
- Age of Onset: Both UC and CD typically peak in ages 15 to 30, but can occur at any age.
- Course of Disease: Both are chronic diseases with periods of remission and active disease.
- Diarrhea: Both diseases typically involve diarrhea, but UC often presents more severe diarrhea with blood and mucus, while CD may have less severe diarrhea without obvious blood or mucus.
- Abdominal Pain: UC is characterized by cramping in the left lower quadrant (LLQ) relieved by defecation, whereas CD presents with cramping or steady pain in the right lower quadrant (RLQ) or periumbilical area, with tenderness and masses in the RLQ.
- Nutritional Deficits: Both can lead to nutritional deficits, but CD often involves more severe deficits including anemia, weight loss, and multiple vitamin and mineral deficiencies.
- Constitutional Manifestations: UC may present fever and associated arthritic, skin, or other organ involvement, such as erythema nodosum or uveitis. While CD is likely to present with fever, malaise, fatigue, and possible associated conditions or urinary complications.
- Pathological Depth of Involvement: UC mainly impacts the mucosa, while CD is characterized by transmural (entire bowel wall) involvement.
- Portion of Bowel Involved: UC typically affects the rectum and sigmoid colon, potentially extending to the entire large bowel. In contrast, CD can impact any portion of the gastrointestinal tract, but primarily affects the terminal ileum and ascending colon.
- Distribution: UC is continuous from the rectum, while CD exhibits patchy involvement with skip lesions.
- Appearance of Mucosa: UC results in granular, dull, hyperemic, and friable mucosa with uniform disease in affected bowel that can potentially form pseudopolyps, whereas CD presents with a cobblestone appearance with areas of healthy tissue surrounded by ulceration and fissures.
- Complications: While both can cause complications, UC frequently leads to acute toxic megacolon, perforation, and massive hemorrhage, while CD often involves obstruction, fistulization, abscess formation, and malabsorption.
- Long Term: Both can lead to cancer, but UC is more likely to develop colorectal cancer, while CD can lead to colon cancer.
Ulcerative Colitis - Clinical Manifestations
- Diarrhea is the most common manifestation of UC.
- While scoring tools exist, they are typically reserved for research purposes.
- Clinically, UC is categorized into three severity levels:
-
Mild UC:
- Fewer than 4 stools daily with or without small amounts of blood.
- No signs of systemic toxicity (e.g., no tachycardia).
- Normal C-reactive protein (CRP) and/or erythrocyte sedimentation rate (ESR).
- Mild abdominal cramping, tenesmus (painful but ineffective urge to defecate), and periods of constipation are common, but severe abdominal pain, profuse bleeding, fever, and weight loss are not typically present.
-
Moderate UC:
- Frequent loose, bloody stools (4 to 6 per day).
- Mild anemia not requiring transfusions (hemoglobin > 10 g/dL).
- Mild abdominal pain.
- No or minimal signs of systemic toxicity.
- Usually maintains adequate nutrition, and weight loss is uncommon.
-
Severe UC:
- Frequent loose, bloody stools (6 or more per day) with severe cramping.
- Evidence of systemic toxicity: fever (temperature ≥ 37.8°C), tachycardia (heart rate ≥ 90 beats per minute), and anemia (hemoglobin < 10 g/dL).
