Study Notes
Crohn Disease - Manifestations
- Crohn disease is a chronic inflammatory bowel disease impacting the GI system.
- Symptoms vary widely, influenced by the location and severity of GI involvement.
-
Common symptoms:
- Persistent diarrhea
- Abdominal pain and tenderness, often relieved by defecation
- Fever, fatigue, and weight loss
- Anorectal lesions (e.g., fissures, ulcers, fistulas, abscesses)
Crohn Disease - Severity
- Crohn disease severity is assessed using the:
- Crohn’s Disease Activity Index (CDAI)
- Harvey-Bradshaw index
- Both indexes correlate and can be used to classify disease severity:
-
Clinical remission: CDAI < 150
- Asymptomatic without inflammatory sequelae.
- Achieved spontaneously or through medical/surgical intervention.
-
Mild Crohn disease: CDAI 150-220
- Ambulatory, tolerating an oral diet.
-
Moderate Crohn disease: CDAI 220-450
- Requires medication to manage symptoms.
-
Severe Crohn disease: CDAI > 450
- Persistent symptoms despite medication.
- May involve hospitalization due to fever, vomiting, obstruction, abscess, or other complications.
-
Clinical remission: CDAI < 150
Crohn Disease - Complications
-
Intestinal obstruction: Common complication caused by bowel inflammation and scarring leading to fibrosis and stricture.
- Symptoms: Abdominal distention, cramping pain, hyperactive bowel sounds (borborygmi), nausea, and vomiting.
- Fistulas: May be asymptomatic, especially when occurring between loops of small bowel.
-
Abscess: Formed by fistulization, causing chills, fever, abdominal mass, and elevated white blood cell count.
- Fistulas between the small bowel and colon can exacerbate diarrhea, weight loss, and malnutrition.
- Bladder involvement: Recurrent urinary tract infections (UTIs).
- Bowel perforation: Uncommon, but can lead to generalized peritonitis.
- Massive hemorrhage: Uncommon complication.
- Colorectal cancer: Increased risk with long-standing Crohn disease.
Hemorrhage
- Symptoms include pale mucous membranes, thirst, light-headedness, hypotension, reduced urine output
- Treatment includes blood transfusions, iron supplements, IV fluids, possibly surgery to remove damaged bowel, possibly vasoconstrictive medications
Megacolon
- Symptoms include fever, tachycardia, hypotension, dehydration, abdominal tenderness and cramping, change in the number of stools per day
- Treatment includes fecal disimpaction, enemas, suppositories, bowel decompression, colonoscopic decompression, bowel habit retraining, total abdominal colectomy
Diarrhea
- Symptoms include frequent loose stools, abdominal cramping, abdominal tenderness, stool that may or may not contain blood, thirst, dehydration, hypovolemia, malnutrition
- Treatment includes monitoring of intake and output, IV fluid, antidiarrheal medications (should be avoided in severe UC), possible guaiac testing
Fistulas
- Symptoms may include being asymptomatic between bowel loops, between bowel and bladder—frequent UTIs, between bowel and abdominal cavity—abscess, chills and fever, a tender abdominal mass, leukocytosis, between small bowel and colon—weight loss, malnutrition, possible exacerbation of diarrhea
- Treatment includes symptomatic treatment: antibiotics, antidiarrheal medication, IV fluid support, possible dissection of section of bowel with fistula if tissue cannot be repaired
