Fecal levels of leukocyte markers reflect disease activity in patients with ulcerative colitis

OBJECTIVE: A prominent feature of inflammatory bowel disease (IBD) is the presence of inflammatory cells in the gut mucosa, and which contribute to the ongoing inflammatory process. The aim of the study was to evaluate fecal neutrophil, eosinophil, mast cell and macrophage markers in the assessment of disease activity in patients with ulcerative colitis (UC). METHODS: Twenty-eight patients with active UC; 4 with proctitis, 16 with left-side colitis and 8 with total colitis, were included in the study. Patient history, endoscopy and histopathology were examined and fecal and serum samples were evaluated at inclusion and after 4 and 8 weeks of treatment. Fecal samples were analysed for myeloperoxidase (MPO), eosinophil protein X (EPX), mast cell tryptase, IL-1beta and TNF-alpha using immunoassays. Blood samples were analysed for MPO, EPX, C-reactive protein, orosomucoid and leucocyte counts. RESULTS: Fecal MPO and IL-1beta levels were elevated in all patients at inclusion despite different disease extensions. Striking reductions in fecal levels of MPO, EPX, tryptase and IL-1beta were observed after 4 weeks of treatment in 20/28 patients with complete remission after 8 weeks. No further reductions were seen in 20/27 patients at 8 weeks. Endoscopic score correlated to IL-1beta at all visits (p<0.01), to MPO at visits 2 and 3 (p<0.05, p<0.001), EPX at visit 2 (p<0.05) and tryptase at visit 3 (p<0.01). Levels of fecal markers also related to histological indices of the disease. CONCLUSIONS: Measurements of fecal MPO, EPX and IL-1beta could be objective complements to endoscopical and histopathological evaluations in the daily care of patients with UC.

Tumor necrosis factor-alpha in serum of patients with inflammatory bowel disease as measured by a highly sensitive immuno-PCR.

BACKGROUND: The significance of serum concentrations of tumor necrosis factor-alpha (TNF-alpha) in the pathogenesis of inflammatory bowel disease (IBD) is uncertain. We measured TNF-alpha in serum from IBD patients by immuno-PCR to analyze the relationship between TNF-alpha and pathophysiologic state in IBD. METHODS: Serum samples were collected from 54 healthy blood donors, 29 patients with ulcerative colitis (UC; 46 samples), and 7 patients with Crohn disease (CD; 8 samples). DNA label was generated by PCR amplification using biotinylated primer and was bound with streptavidin to biotinylated third antibody. TNF-alpha sandwiched by antibodies was detected by PCR amplification of the DNA label. RESULTS: TNF-alpha could be measured in all samples. The median serum concentration in IBD patients overall was approximately 390-fold higher than in healthy donors (median increase, 380-fold for UC, 640-fold for CD). The median serum TNF-alpha concentration was 1.7-fold higher in the active stage of UC than in the inactive stage (P <0.05), and this difference could be detected in individual patients. CONCLUSIONS: Sensitive measurement of serum TNF-alpha could provide an important pathophysiologic marker for the presence and activity of IBD.     

Serum interleukin-18 concentrations in patients with inflammatory bowel disease

Elevated expression of interleukin (IL)-18 mRNA and protein in intestinal mucosa, attributable to activated monocytes and macrophages in that site, has been reported in patients with inflammatory bowel disease (IBD). However, changes in serum IL-18 concentrations in patients with IBD have not been reported. We measured bioactive IL-18 in serum from patients with IBD, using an enzyme-linked immunosorbent assay (ELISA). Mean serum IL-18 concentrations in 5 patients with Crohn disease (CD) were 400 pg/mL, approximately 1.7 times higher than concentrations in 21 control subjects (p < 0.01). However, serum IL-18 was not increased in patients with ulcerative colitis (UC). These results suggest that like other T-helper type 1 (Th1) cytokines IL-18 may play a key pathogenetic role in Th1-mediated disorders, such as CD. Regulation and expression of IL-18 appears to differ between CD and UC, and serum IL-18 may be a useful clinical marker for CD.

Does the urinary excretion of α1-microglobulin and albumin predict clinical disease activity in ulcerative colitis?

Introduction  There remains some difficulty in determining disease activity during the development of inflammatory bowel disease (IBD). The excretion levels of some inflammatory response molecules increase as a result of the onset of this disease. We studied urinary alfa-1-microglobulin (α1-MG) and albumin levels in patients with active and inactive ulcerative colitis (UC) and investigated whether we could use these parameters as an activity index. Methods  The study was carried out at Gazi University Faculty of Medicine, Nephrology and Gastroenterology Departments, between December 2003 and March 2006. In total, 35 patients (male/female: 16/19, mean age: 38.3±2.4 years) and 13 healthy controls (male/female: 6/7, mean age: 35.8±2.8 years) were enrolled in the study. Nineteen patients had symptoms of active disease and the remaining 16 patients had inactive disease. Results  There was a significant difference in serum C-reactive protein (CRP), urinary albumin excretion, and α1-MG excretion levels between patients and controls. Patients with active disease had significantly higher serum CRP and α1-MG levels than those with inactive disease and controls. Patients with active disease had higher microalbuminuria levels than inactive patients, but this difference was not statistically significant. Urinary albumin and α1-MG excretion did not correlate with serum CRP levels. Conclusion  The present study suggests that, as with CRP, urinary levels of albumin and α1-MG increase during the active period of UC. During the inactive period, concentrations of these parameters are comparable to controls. The measurement of α1-MG and/or microalbuminuria could provide information on disease severity and response to treatment.
