What parameters does CDAI use?

CDAI (Best 1976): 8 weighted variables over 7 days: stool frequency, abdominal pain, general well-being, extraintestinal manifestations, antidiarrhoeal use, abdominal mass, haematocrit, body weight deviation. Each multiplied by a weighting factor.

What CDAI defines clinical remission?

CDAI 450 = severe. Clinical response is typically defined as a decrease of >= 100 points; remission as CDAI < 150.

What are limitations of CDAI?

CDAI does not incorporate endoscopic or laboratory data. Symptoms can be confounded by IBS-type symptoms, strictures, or post-operative anatomy. Biomarkers (CRP, faecal calprotectin) and endoscopy are needed for mucosal healing assessment.
