Abstract
Serum tumor necrosis factor (TNF) levels in 33 patients with inflammatory bowel disease (IBD) were measured by using a sensitive enzyme immunoassay. Four of five Crohn's diseases (CD) and nine of twenty eight ulcerative colitis (UC) had elevated levels of serum TNF. In active CD or UC, a greater fraction of patients studied had significantly increased serum TNF levels (3/3 for CD and 8/11 for UC). Production of TNF by peripheral blood monocytes when stimulated by lipopolysaccharide was also increased in these patients and correlated with their serum TNF levels. These results suggest that TNF may have some pathoetiological meaning in IBD.
