【摘要】目的 比较匹多莫德与甘露聚糖肽治疗小儿哮喘的临床疗效。方法选取2012年7月—2013年7月中山市黄圃人民医院呼吸科收治的哮喘患儿120例,随机分为研究组和对照组,每组60例。两组患儿均给予常规治疗,对照组患儿加用甘露聚糖肽治疗,研究组患儿加用匹多莫德治疗。比较两组患儿哮喘控制效果,随访1年记录两组患儿哮喘急性发作次数、呼吸道感染次数及呼吸道感染持续时间,比较入院后1 d和出院当日细胞分数细胞分数、补体C3、免疫球蛋白A(IgA)、中性粒细胞计数和自然杀伤细胞(NK细胞)分数。结果研究组患儿哮喘控制效果优于对照组(u=5.321,P=0.000)。研究组患儿哮喘急性发作次数和呼吸道感染次数少于对照组,呼吸道感染持续时间短于对照组(P<0.05)。入院后1 d两组患儿细胞分数细胞分数、补体C3、IgA、中性粒细胞计数及NK细胞分数比较,差异无统计学意义(P>0.05);出院当日研究组患儿细胞分数、补体C3、IgA及中性粒细胞计数高于对照组(P<0.05);出院当日两组患儿细胞分数和NK细胞分数比较,差异无统计学意义(P>0.05)。出院当日两组患儿细胞分数细胞分数、补体C3、IgA、中性粒细胞计数及NK细胞分数均高于入院后1 d(P<0.05)。结论匹多莫德治疗小儿哮喘的临床疗效优于甘露聚糖肽,能有效减少患儿哮喘发作、呼吸道感染并改善其免疫功能,且未增加不良反应发生风险。

小儿哮喘是儿科常见的慢性呼吸系统疾病,是一种由多种细胞和细胞组分参与的气道慢性炎性疾病[1],其主要临床表现为可逆性气流受限引起的喘息、气促和胸闷等[2]。流行病学调查显示,小儿哮喘发病率为3%~5%[3]。目前,临床上治疗小儿哮喘主要采用β2受体激动剂、糖皮质激素及非甾体类药物[4]。由于哮喘是一种炎性疾病,因此改善患者免疫功能有助于预防哮喘。匹多莫德是一种具有生物活性的免疫促进剂,已有研究证实其可以改善小儿免疫功能[5]。甘露聚糖肽是从酵母细胞壁中提取的抗原活性物质,具有增强及调节免疫功能的作用[6]。有研究显示,匹多莫德与甘露聚糖肽治疗小儿哮喘均有效,但比较两种药物治疗小儿哮喘临床疗效的报道较少。本研究旨在比较匹多莫德与甘露聚糖肽治疗小儿哮喘的临床疗效。

【Abstract】Objective To compare the clinical effect on infantile asthma between pidotimod and mannatide.MethodsFrom July 2012 to July 2013,a total of 120 children with asthma were selected in the Department of Respiratory Medicine,Huangpu People′s Hospital of Zhongshan,and they were randomly divided into control group and study group,each of 60 cases.Based on conventional treatment,children of control group were given mannatide,while children of study group were given pidotimod.Asthma control cell cell percentage,alexin C3,IgA,neutrophil count and NK cell percentage after 1 day of admission and on the day of discharge were compared between the two groups;children of the two groups were followed up for 1 year to observe the times of acute attack of asthma and respiratory tract infection,and single infection duration.ResultsThe asthma control effect of study group was statistically significantly better than that of control group(u=5.321,P=0.000).No statistically significant differences of cell cell percentage,alexin C3,IgA,neutrophil count or NK cell percentage was found between the two group after 1 day of admission,nor was cell percentage or NK cell percentage between the two groups on the day of discharge(P>0.05),while cell percentage,alexin C3,IgA and neutrophil count of study group were statistically significantly higher than those of control group on the day of discharge(P<0.05). cell cell percentage,alexin C3,IgA,neutrophil count and NK cell percentage on the day of discharge of the two groups were statistically significantly higher than those after 1 day of admission(P<0.05).ConclusionPidotimod has better clinical effect in treating infantile asthma than mannatide,can more effectively reduce the asthmatic attack and incidence of respiratory tract infection,improve the immunologic function.
