Understanding Crohn's Disease and CDAI
What is Crohn's Disease?
Crohn's disease is a lifelong inflammatory bowel disease that can affect any segment of the gastrointestinal tract from mouth to anus. It is characterized by chronic inflammation, causing various symptoms and complications that significantly impact quality of life.
Common Symptoms
- •Abdominal Pain: Cramping and discomfort
- •Diarrhea: Frequent, sometimes bloody stools
- •Weight Loss: Due to malabsorption and reduced intake
- •Fatigue: From chronic inflammation and anemia
CDAI Development and Use
Clinical Trials: Standardized endpoint measurement
Disease Management: Objective assessment of activity
Quality of Life: Comprehensive symptom evaluation
Important Clinical Notes
Remission Definition: CDAI <150 indicates clinical remission and is the target for treatment.
Treatment Response: A reduction of ≥70 points from baseline indicates clinically meaningful improvement.
Severe Disease: CDAI >450 indicates severe activity requiring intensive management.
Limitations: CDAI doesn't assess endoscopic healing or histological improvement.
Complementary Assessments: Should be used alongside endoscopic findings and biomarkers.
