Abstract
AIM
To investigate the effects of the expression of Th1/Th2 cytokines in intestinal mucosa with ulcerative colitis.
METHODS
Thirty patients (24 males, 6 females, age 18-79 years) with severe ulcerative colitis (UC) were examined by colonoscope, the diagnosis was confirmed by histological method. Bacterial infection was excluded through consecutive stool cultures twice. And ameba, schistosomiasis, gastroen-terological cancer and endocrine diseases were also excluded. Ulcerative colitis was found in omni-colon (n = 15) , sigmoid (n = 9), rectum (n = 6), respectively. Its clinical categories included relapse (n = 20), persistent (n = 7) and initial (n = 3).They were treated by Sulphasalazine (SASP) and glucocorticoid after histological diagnosis. Eight weeks later, they were re-examined by colonoscope. The expression of cytokines in the intestinal mucosa of UC patients were detected by a semi-quantitative assay, reverse transcription-polymerase chain reaction(RT-PCR) before and after treatment respectively.
RESULTS
Comparison with control groups, the expression of TNF-α, IL-2 was increased but IL-4 was decreased in the intestinal mucosa in acute stage. Sulphasalazine (SASP) and glucocorticoid inhibited inflammation by reducing the expression of TNF-α from 1.22±0.02 to 0.78±0.08 (P<0.01) and of IL-2 from 0.82±0.06 to 0.47±0.04 (P<0.01), and elevate the expression of IL-10 from 0.68±0.03 to 0.91±0.02(P<0.01).
CONCLUSION
There is an imbalance of Th1 and Th2 phenotype cytokine in patients with ulcerative colitis.
