DISEASE DEFINITION
Several cause exist for inflammation of the gut such as infection, toxin, autoimmune reaction, radiation and ischemia. When none of these causes are identified, a group of diseases with unknown etiology remains which are called chronic inflammatory bowel deseases (IBD). The chronic inflammatory bowel diseases include two distinet entities, ulcerative colitis (UC) and Crohn′s disease (CD), although there is a small group of patients with an intermediate form. 相似文献

AIM:To determine the tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6) and soluble interleukin 2 receptor (sIL-2r) from peripheral blood mononuclear cells (PBMC) in 25 Chinese patients with ulcerative colitis and 20 healthy controls.METHODS:PBMC were isolated by density gradient centrifugation of heparinized blood and cultures for 24 or 48 hours by stimulation with LPS or PHA. TNF-alphaand sIL-2r were measured by ELISA method and IL-6 measured by biossay.RESULTS:TNF-alphaproduction stimulated by LPS and sIL-2r production by PHA in ulcerative colitis were significantly lower than in healthy controls (TNF-alpha509(46-7244)ng/L vs 1995(117-18 950)ng/L, P < 0.05; sIL-2r 320U/mlplus minus 165U/ml vs 451U/mlplus minus 247U/ml, P < 0.05).Spontaneous TNF-alphaand sIL-2r production were not significantly different between ulcerative colitis and controls (TNF-alpha304(46-7044)ng/L vs 215(46-4009)ng/L,P > 0.05; sIL-2r 264U/mlplus minus 115U/ml vs 236U/mlplus minus139U/ml, P>0.05). IL-6 production by spontaneous release from PBMC in ulcerative colitis group was 109U/mlplus minus 94U/ml vs 44U/mlplus minus 39U/ml for those in healthy controls, P < 0.01. IL-6 stimulated by LPS in ulcerative colitis group was (261U/ml plus minus 80U/ml) higher than in healthy controls (102U/mlplus minus 54U/ml, P < 0.01). No correlation of TNF-alpha, IL-6, sIL-2r production was found to disease activity, disease location and medication.CONCLUSION:Cytokine production from PBMC was also disturbed in Chinese patients with ulcerative colitis. 相似文献

AIM: To analyze clinical features and response to treatment in inflammatory bowel disease (IBD) patients from the Hubei Province of China.METHODS: Clinical data was collected retrospectively from 74 patients with IBD [66 with ulcerative colitis (UC) and 8 with Crohn’s disease (CD)] admitted to The Second Hospital, Hubei Medical University from 1986 to 1995.RESULTS: The most common symptoms in IBD patients were abdominal pain, diarrhea, blood and mucus in stool, and constipation. Extraintestinal manifestations of IBD were not common. In these patients, inflammation was predominantly located in the sigmoid and left colon in UC cases, and in the ileum and colon in CD cases. Treatment with sulphasalazine and corticosteroids was effective in 95% of UC cases; However, about 42% of UC patients showed disease recurrence during the follow-up period of 1.11 years. Five out of eight CD patients had part of their intestine removed, whereas three were treated with anti-tuberculosis drugs or the antibiotic metronidazole. Out of four patients we followed up for 1-8 years, one died of severe complications after surgery, two experienced recurrence while in treatment with drugs, and one remained in remission under sulphasalazine treatment after surgery.CONCLUSION: Five percent of the patients reported a family history of IBD. About 34% of the patients were smokers and 32% of the patients were alcoholic. Epidemiological studies are urgently needed in the Hubei Province of China to assess the role that genetics and environmental factors play in the pathogenesis of inflammatory bowel diseases. 相似文献
