摘要
背景:肝硬化患者易发生多种感染,与免疫功能下降、肠道菌群紊乱有关。目的:观察口服微生态制剂对肝硬化患者细胞免疫功能、外周血单核细胞内毒素受体表达以及血清细胞因子和血浆内毒素水平的影响。方法:选取连续入院的肝硬化患者,予常规保肝治疗和口服微生态制剂4周,应用流式细胞术检测患者治疗前后外周血T细胞及其亚群和自然杀伤细胞、外周血单核细胞内毒素受体Toll样受体(TLR)4和CD14的表达,分别以酶联免疫吸附测定法和偶氮基质显色法检测细胞因子白细胞介素(IL)-1β、肿瘤坏死因子(TNF)-α、IL-10水平和血浆内毒素水平。结果:治疗前肝硬化患者外周血总T细胞(CD3)和CD4细胞数明显低于正常对照组(P<0.05),微生态制剂治疗后CD3和CD4亚群显著升高(P<0.05)。治疗前肝硬化患者外周血单核细胞内毒素受体TLR4和CD14的表达显著高于正常对照组(P<0.01),微生态制剂治疗后CD14表达显著降低(P<0.01),TLR4表达也呈下降的趋势,但差异无统计学意义。治疗前肝硬化患者血清IL-1β、TNF-α、IL-10水平显著高于正常对照组(P<0.05),微生态制剂治疗后血清细胞因子和血浆内毒素水平均无明显改变。结论:肝硬化患者存在细胞免疫功能下降和慢性炎症状态,微生态制剂可改善患者免疫功能的紊乱,因此可将其作为一种慢性肝病的辅助治疗。
