Interrelations between interleukin-6, interleukin-1 beta, plasma C-reactive protein values, and in vitro C-reactive protein generation in patients with inflammatory bowel disease.

Abstract

Acute phase proteins are released from the liver in response to cytokines, and

Serum C-reactive protein levels predict neurological outcome after aneurysmal subarachnoid hemorrhage

“…It is strongly stimulated by interleukin-6 [1][2][3]6,7,[20][21][22][23] . Additionally, IL-1, which has been implicated in the pathogenesis of cerebral vasospasm, also provides a strong stimulus for CRP synthesis 1,[3][4][5] .…”

Is interleukin-6 important in inflammatory bowel disease?

“…The present study provides evidence that the IL-6 gene is involved in determining susceptibility and disease Table 2 Functional effect of biallelic G/A polymorphism in the 4th intron of IL-6 and IL-6 VNTR polymorphism on IL-6 protein production in whole blood samples stimulated with 10 g/mL LPS for 24 h. Ulcerative colitis (UC) and Crohn's disease (CD) patients were not undergoing any steroid treatment for at least a month prior to assay (17) phenotype in Crohn's disease patients. A modest increase in the frequency of the less common IL-6*G allele was noted in Crohn's disease when compared to ulcerative colitis patients and healthy controls.…”

“…[13][14][15][16] Other studies have shown that IL-6 production by isolated monocytes in vitro, both spontaneously and after LPS stimulation, is similar in IBD patients and healthy controls. 10,17 When these results were re-analysed accounting for the number of monocytes per 10 ml, the stimulated IL-6 production was increased in CD compared to UC and healthy controls. 17 We were unable to confirm any of these observations since our results showed marginally lower IL-6 production in CD patients.…”

The more likely explanation is a methodological one.…”

Kallikrein – Kinin System and Coagulation System in Inflammatory Bowel Diseases

“…The lower levels of coagulation intermediates or fragments in UC patients, as compared with Crohn's disease, may be simply due to more superficial distribution of intestinal inflammation always found in UC. In addition patients with Cronh's disease have higher tissue IL-1 and plasma IL-6 levels (Mazlam & Hodgson, 1994). A role of intrinsic coagulation activation pathway, associated with the contact system, in IBD is unclear.…”
