Crohn’s Disease

Crohn's Disease is a chronic, relapsing, transmural inflammatory bowel disease (IBD) that can affect any segment of the gastrointestinal tract from the mouth to the anus, most commonly involving the terminal ileum and colon.

The etiology is multifactorial, arising from an inappropriate mucosal immune response to gut microbiota in genetically susceptible individuals. Environmental triggers include cigarette smoking, a Western diet (high-fat, high-sugar), stress, and frequent NSAID use. Key susceptibility genes include NOD2/CARD15.

Crohn's disease is characterized by patchy, transmural inflammation ("skip lesions") of the gut wall. Dysregulated Th1 and Th17 cell immune responses lead to mucosal damage, deep linear ulcerations (producing a "cobblestone" appearance), non-caseating granulomas, and muscular hypertrophy, which eventually promotes fibrosis, stricture formation, and fistulization.

• Prevalence: Highest in North America and Northern Europe (approx. 300 per 100,000).
• Age: Bimodal distribution with a primary peak at 15–30 years and a secondary peak at 50–70 years.
• Gender: Slightly more prevalent in females.

• Family history of inflammatory bowel disease
• Active cigarette smoking
• Caucasian or Ashkenazi Jewish descent
• Urban residence
• High intake of refined sugars and saturated fats

• Vital Signs: Tachycardia and low-grade fever during active flares.
• Inspection: Pallor (anemia), aphthous ulcers in oral cavity, abdominal distension, perianal skin tags or draining fistulas.
• Palpation: Tenderness in the right lower quadrant; palpable inflammatory mass.
• Auscultation: Hyperactive or high-pitched bowel sounds in early obstruction; absent bowel sounds in ileus/perforation.

• A. Clinical Assessment: History of chronic abdominal pain, weight loss, and diarrhea.
• B. Laboratory Testing: Blood panels for anemia and inflammation markers, and stool tests to rule out infections.
• C. Imaging Studies: CTE, MRE, or colonoscopy with ileoscopy showing segmental, transmural inflammation.
• D. Functional Tests: Video capsule endoscopy (contraindicated in known strictures).
• E. Biopsy Findings: Non-caseating granulomas, focal cryptitis, crypt distortion.
• F. Genetic Testing: Not routinely recommended for clinical diagnosis.
• G. Differential Diagnosis: Distinguishing from ulcerative colitis, celiac disease, and infectious colitis.

C-Reactive Protein (CRP)
Type: Blood Test
Purpose: Assess systemic inflammatory activity.
Expected Findings: Elevated CRP levels.
Interpretation: Correlates with active mucosal inflammation and clinical flares. Fecal Calprotectin
Type: Stool Test
Purpose: Assess localized intestinal mucosal inflammation.
Expected Findings: Significantly elevated (>250 µg/g).
Interpretation: Highly sensitive for distinguishing IBD from irritable bowel syndrome (IBS).

• Magnetic Resonance Enterography (MRE): - Purpose: Assess the small bowel without radiation. - Typical Findings: Segmental wall thickening, hyperenhancement, and comb sign (mesenteric hypervascularity). - Clinical Importance: Identifies transmural inflammation and strictures.
• CT Enterography (CTE): - Purpose: Evaluate acute abdominal complications. - Typical Findings: Bowel wall thickening, fluid collections, or free air. - Clinical Importance: Fast diagnostic imaging choice for suspected abscess or perforation.

• Ulcerative Colitis: Involves only the colon continuously from the rectum upward, mucosal-only inflammation, no skip lesions.
• Infectious Colitis: Acute onset, positive stool cultures, resolves spontaneously or with antibiotics.
• Celiac Disease: Malabsorption resolved by a gluten-free diet; positive tTG-IgA antibodies.

• Fibrotic bowel strictures/obstructions
• Enterocutaneous, enteroenteric, or perianal fistulas
• Intra-abdominal abscesses
• Severe malnutrition and osteoporosis
• Colorectal cancer (especially with long-standing colitis)

Crohn's disease is a life-long, relapsing condition. While there is no cure, over 70% of patients live active lives with appropriate medical maintenance. Approximately 60–70% of patients eventually require at least one surgical intervention.

• Primary: No proven primary prevention methods.
• Secondary: Strict adherence to maintenance therapy and permanent smoking cessation.
