Abstract

Objective To investigate the influence of olsalazine on tumor necrosis factor-alpha (TNF-α) and interleukin-10 (IL-10) in patients with chronic ulcerative colitis.Methods Sixty patients with chronic ulcerative colitis (observation group),including 22 chronic recurrent cases and 38 chronic persistent cases,were enrolled and treated with olsalazine.Meanwhile,60 healthy volunteers without disease history of ulcerative colitis were selected as control group.The concentrations of TNF- α and IL-10 in serum of the two groups were detected by ELISA and compared.Results Before treatment,the concentration of TNF- α in serum of the observation group was significantly higher than that of control group [ (57.2 ± 10.1 )ng/L vs.(27.2 ± 6.9) ng/L],while IL-10 was significantly lower than that of control group[ (9.2 ± 2.1 ) ng/L vs.(17.3 ±2.9) ng/L] (P ＜0.05).Before treatment,the concentration of TNF-α in serum in chronic persistent patients and chronic recurrent patients[ (56.9 ± 9.9),(57.3 ± 9.7) ng/L ] were significantly higher than that in control group,and serum IL-10 in chronic persistent patients and chronic recurrent patients [ (9.1 ± 2.3 ),(8.4 ± 2.5 ) ng/L ] was significantly lower than that in control group (P＜ 0.05 ).The concentration of TNF- α in serum in observation group after treatment was obviously lower than that before treatment [(28.1 ±8.9) ng/L vs.(57.2 ± 10.1 ) ng/L],and IL-10 was obviously higher than that before treatment [(13.4 ± 10.7) ng/L vs.(9.2 ±2.1 )ng/L] (P ＜ 0.05).The concentration of serum TNF-αand IL-10 in chronic persistent and chronic recurrent patients before and after treatment had statistical significance (P＜0.05 ).Conclusions Olsalazine can significantly decrease the concentration of TNF- α and increase the concentration of IL-10 in serum in patients with chronic ulcerative colitis.It is worthy of application in clinic. Key words: Colitis, ulcerative; Tumor necrosis factor-alpha; Interleukin-10; Olsalazine
