[摘要] 目的 研究地衣芽孢杆菌辅助治疗溃疡性结肠炎(UC)的临床疗效及可能机制。 方法 将46例住院治疗的UC患者随机分成对照组及研究组,每组23例。对照组给予口服美沙拉嗪肠溶片1.0 g/次、4次/d,研究组在对照组基础上加用地衣芽孢杆菌活菌胶囊0.5 g/次、3次/d。疗程均为2个月。比较两组患者治疗前及治疗2个月后 Mayo疾病活动性评分、临床疗效及血清IL-17、IL-23、TNF-α水平。 结果 两组治疗后Mayo评分均较治疗前明显下降(P均<0.01),且以研究组降幅明显(P<0.01)。两组治疗总有效率无明显差异(P>0.05),但研究组显效率高于对照组(P<0.05)。两组治疗后血清IL-17、IL-23、TNF-α水平均较治疗前明显下降(P均<0.01),研究组IL-17、IL-23、TNF-α水平降低更明显(均P<0.01)。 结论 地衣芽孢杆菌联合美沙拉嗪较单用美沙拉嗪能更好地改善UC患者临床症状,可能与地衣芽孢杆菌协同下调血清IL-17、IL-23、TNF-α水平有关。

[Abstract] Objective To investigate the clinical effect of bacillus licheniformis in auxiliary treatment of ulcerative colitis (UC) and its possible mechanism. Methods A total of 46 cases of hospitalized patients with UC were randomly divided into control group (n=23) and study group (n=23). The control group was given treatment of mesalazine (1.0 g/times, 4 times/day), on the basis of this, the study group was treated with bacillus licheniformis capsule (0.5 g/times, 3 times/day). The course of treatment was 2 months. The Mayo disease activity score, clinical efficacy and serum IL-17, IL-23 and TNF-α levels were compared between the two groups before and after 2 months of treatment. Results The Mayo scores of the two groups after treatment were significantly lower than those before treatment(all P<0.01), and the study group decreased significantly (P<0.01). There was no significant difference in total effective rate between the two groups (P>0.05), but the effective rate of the study group was higher than that of the control group(P<0.05). After treatment, serum IL-17, IL-23 and TNF-α levels were significantly lower than those before treatment in two groups (all P<0.01), and the levels of IL-17, IL-23 and TNF-α were significantly lower in the study group(all P<0.01). Conclusion The combination of bacillus licheniformis and mesalazine can better improve the clinical symptoms of UC patients, it may be associated with the down-regulation of serum IL-17, IL-23, TNF-α levels.

溃疡性结肠炎(ulcerative colitis,UC)是一种主要累及结直肠黏膜的慢性非特异性炎症性疾病,临床以反复发作的黏液脓血便、腹痛、腹泻为主要症状。近年UC在我国的发病率逐渐上升,但病因及发病机制尚不明确。研究发现[1-2],肠道菌群失调是引起腸道免疫紊乱的重要因素,其在UC发病过程中起着重要作用,益生菌有助于改善UC患者临床症状,但具体机制尚不明确。本研究通过观察美沙拉嗪及美沙拉嗪联合地衣芽孢杆菌治疗UC的临床疗效,并比较两组治疗前后白细胞介素(interleukin,IL)-17、IL-23、TNF-α水平,探讨地衣芽孢杆菌治疗UC的可能机制。
