In a prospective study we compared the usefulness of various laboratory tests (albumin, alpha-1-proteinase inhibitor (A1PI), cholinesterase (CHE), C-reactive protein, erythrocyte sedimentation rate, hematocrit) and activity indices (CDAI, VHAI) in relation to the disease activity by endoscopic criteria. Except for hematocrit highly significant differences (p less than 0.0005) of the mean values of all test results were found for patients without or with slight mucosal lesions compared with patients with severe inflammation of the mucosa. Further analysis of the data indicates the highest test efficiency (84%), sensitivity (80%), and specificity (88.6%) for CHE. CHE showed good correlations to all other tests; the highest correlation was found between CHE and VHAI (r = -0.78). We suggest that a suppression of CHE synthesis mediated by endotoxins and cytokines rather than an increased intestinal loss explains the decreased CHE in severe Crohn's disease. It is concluded from the data that CHE is a useful test to assess the inflammatory activity of Crohn's disease.

UI	MeSH Term	Description	Entries
D007422	Intestines	The section of the alimentary canal from the STOMACH to the ANAL CANAL. It includes the LARGE INTESTINE and SMALL INTESTINE.	Intestine
D008297	Male		Males
D011237	Predictive Value of Tests	In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

D002097	C-Reactive Protein	A plasma protein that circulates in increased amounts during inflammation and after tissue damage. C-Reactive Protein measured by more sensitive methods often for coronary heart disease risk assessment is referred to as High Sensitivity C-Reactive Protein (hs-CRP).

D003424	Crohn Disease	A chronic transmural inflammation that may involve any part of the DIGESTIVE TRACT from MOUTH to ANUS, mostly found in the ILEUM, the CECUM, and the COLON. In Crohn disease, the inflammation, extending through the intestinal wall from the MUCOSA to the serosa, is characteristically asymmetric and segmental. Epithelioid GRANULOMAS may be seen in some patients.

D006400	Hematocrit	The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.
