手足口病(hand, foot and mouth disease, HFMD)是临床上常见的疾病,是一种由肠道病毒引起的传染性疾病,其中以柯萨奇病毒感染多见,常发生在1~5岁儿童中,具有传播速度快、病情变化快、传染途径复杂等特点,临床表现为手足口部突发性湿疹,严重者可伴有不同程度的器官损伤,甚至发展为重症肺炎、肺水肿致患儿死亡[1]。文献[2]报道显示:HFMD发病机制复杂,虽然为水疱状疾病,但病程相对较短,1周内即可消退。目前,临床上对于HFMD尚缺乏有效的治疗方法,加强HFMD患儿早期诊断对临床有效的干预治疗具有重要的意义[3]。研究[4]表明:免疫球蛋白(Ig)和超敏C反应蛋白(hs-CRP)在HFMD的发生、发展中发挥了重要的作用,加强患儿Ig和hs-CRP测定能帮助患儿早期确诊,有助于指导临床治疗,但是不同学者试验结果存在争议。因此,本文以2015年10月至2017年10月我院收治的HFMD患儿76例(HFMD组)、健康体检儿童80名(对照组)作为研究对象,探讨Ig和hs-CRP在HFMD患儿中的临床检验效果及价值,现作报道。

摘要:
目的探讨免疫球蛋白(Ig)和超敏C反应蛋白(hs-CRP)在小儿手足口病(HFMD)中检测的临床价值及应用研究。 方法选取HFMD患儿76例(HFMD组),均采用利巴韦林治疗,根据治疗效果又分为好转组和无效组;选择同期儿童健康体检者80名(对照组)。分别检测HFMD组和对照组Ig(IgA、IgG、IgM)和hs-CRP水平,评价2个指标在HFMD的诊断与治疗疗效观察中的敏感性和特异性,并绘制ROC曲线进行相关性分析。 结果观察组Ig中IgA、IgG水平均低于对照组(P < 0.01),而IgM、hs-CRP均高于对照组(P < 0.01);观察组经利巴韦林治疗后64例好转,12例无效;好转组中IgA、IgG水平均高于无效组(P < 0.05),IgM、hs-CRP水平均低于无效组(P < 0.01)。IgA、IgG、IgM和hs-CRP在小儿HFMD中诊断敏感性、特异性差异无统计学意义(P>0.05),Ig联合hs-CRP诊断小儿HFMD敏感性、特异性,高于单一指标(P < 0.05)。 结论Ig和hs-CRP联合检测对于HFMD患儿早期诊断具有辅助筛查作用,且对于已明确患儿疾病严重程度、疾病的进展和指导临床治疗具有较高的临床价值,值得推广应用。 Abstract:ObjectiveTo investigate the clinical value and application research of immunoglobulin(Ig) and hypersensitive C reactive protein(hs-CRP) in children with hand, foot and mouth disease(HFMD). MethodsSeventy-six children with HFMD(HFMD group) were treated with ribavirin, and subdivdied into the improvement group and invalid group according to the therapeutic effects.Eighty health physical examination children were set as the control group.The levels of Ig(IgA, IgG and IgM) and hs-CRP in HFMD group and control group were detected.The sensitivity and specificity of two indexes in the diagnosis and treatment of HFMD were evaluated, and the ROC curve was plotted for correlation analysis. ResultsThe levels of IgA and IgG in HFMD group were lower than those in control group(P < 0.01).The levels of IgM and hs-CRP in HFMD group were higher than those in control group(P < 0.01).After the HFMD group were treated with ribavirin, 64 cases were improved, and 12 cases were invalid.The levels of IgA and IgG in improvement group were higher than those in invalid group(P < 0.05), and the levels of IgM and hs-CRP in improvement group were lower than those in invalid group(P < 0.01).The differences of the sensitivity and specificity of IgA, IgG, IgM and hs-CRP in the diagnosis of HFMD children were not statistically significant(P>0.05).The sensitivity and specificity of Ig combined with hs-CRP in the diagnosis of HFMD children were higher than those of single indicator(P < 0.05). ConclusionsThe joint detection of Ig and hs-CRP plays auxiliary screening function in the early diagnosis of HFDH, can identify the severity and development and guide the clinical treatment, and has high clinic value.It is worthy of promoting. -
