Background:
Increasing numbers of patients with inflammatory bowel disease (IBD) have raised the need for a rapid noninvasive means to monitor disease activity. We validated two rapid tests for faecal calprotectin and one for faecal lactoferrin and compared them to the most common clinical and endoscopic scores, enzyme-linked immunosorbent assay (ELISA) calprotectin test and systemic inflammation markers.
Materials And Methods:
The clinical and endoscopic disease activity of 72 patients with colonic IBD, who underwent ileocolonoscopy, was determined. The patients provided stool samples to measure calprotectin and lactoferrin, and blood samples to measure systemic inflammation markers.
Results:
Rapid calprotectin tests correlated significantly with clinical and endoscopic indices and standard ELISA calprotectin in ulcerative colitis, but not in Crohn's disease. CalDetect correlated more closely with ELISA calprotectin than CerTest FC in concentrations exceeding 200 μg/g. CalDetect was also more sensitive in indicating histological remission or mild disease than was CerTest FC at cut-off of 200 μg/g. CerTest Lactoferrin was comparable to CalDetect in their correlation with clinical, endoscopic and histological scores.
Conclusions:
These rapid tests are suitable for identifying patients with inactive or mildly active disease, but as semiquantitative or qualitative tests, they cannot totally replace ELISA calprotectin in decision-making related to therapy.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
