1、青岛大学硕士学位论文游离HCV核心抗原检测对不同基因型丙肝早期筛选早期治疗影响的研究姓名:张力申请学位级别:硕士专业:免疫学指导教师:高美华20120529中文摘要游离HCV核心抗原检测对不同基因型丙肝早期筛选早期治疗影响的研究摘要目的验证HCV核心(游离)抗原ELISA实验特异性、敏感性及有效缩短HCV检测窗口期的作用。讨论HCV核心(游离)抗原检测和HCVRNA的一致性。比较HCVRNA和HCV核心(游离)抗原阳性、HCVELISA阴性的有危险因素组治疗组和HCVRNA阳性HCV核心(游离)抗原阴性、HCVELISA阳性的治疗对照
2、组不同基因型经一段时间治疗后早期病毒学应答是否有统计学差异。方法比较300份正常体检人群组与35例随访确定HCV感染的有危险因素组HCVRAN和HCV(游离)核心抗原检测情况,危险因素为有与HCV感染者接触的暴露史。对35例有危险因素组中参与治疗的病人和40例病程在一年以上HCV慢性感染治疗对照组病人比较通过《丙型肝炎防治指南》确定治疗方案后治疗12周EVR情况。所有病人均排除其他肝炎病毒感染,均未经抗病毒治疗。结果300份HCVRNA和抗-HCV阴性体检人群组中有1例(0.33%)游离HCV核心抗原阳性,35例确诊HCV感染者丙肝核
3、心抗原初次检测33例为阳性(94.29%),经统计HCV一核心抗原ELISA法比Anti-HCVELISA法缩短窗口期约34—36天。有危险因素组和治疗对照组1型两组病人EVRP4、Anti—HCV阴性有危险因素组EVR均高于HCVRNA阳性HCV核心(游离)抗原阴性、Anti—HCV阳性治疗对照组。HCV核心抗原检测可作为丙肝检测的有效补充实验。关键词:丙型肝炎病毒核心抗原;丙型肝炎病毒核糖核酸;丙型肝炎病毒抗体;早期病毒学应答茎苎塑墨LI㈣__--_-·_-··_··_-_·__-·_-______-__-_-·-_·-__--_-_·___-_-。。oo-_-。__。-‘。。。。。。‘ooooo’o_o_-‘·--_____-____一一一一■'■r'■,●-JTheStudyofFreeHCVcoreAn5、tigenTest’valueinEarlyScreeningandEarlyTreatmentwithDifferentGenotypesforhepatitisCAbstractObjectiveWedetectedthespecificity,sensitivityandeffectivelyofHCVcore(free)antigenELISAtest,andvalidatedthetest’SfunctioninreducingtheHCVwindowperiod.Wediscussedtheconsistencybetwe6、enHCVcore(free)antigendetectionandHCVRNAdetection.WecomparedthestatisticaldifferencesofEVRbetweentheriskfactors’grouptreatedbydifferentgenotypeswhoseHCVRNAandHCVcore(free)antigendectectionwerepositive,andHCVelisadetectionwerenegativeandthematchedgrouptreatedbydifferentg7、enotypeswhoseHCVRNApositivedectectionwerepositive,HCVcore(flee)antigendectectionwerenegative,andHCVelisawarepositive.MethodsWecomparedthetestresultsofHCVRANandHCV(free)coreantigenbetween300casesofnormalphysicalexaminationpopulationgroupand35patientswithHCVinfectiondeter8、minedbyfollow-upwhohadriskfactors.Populationgroups谢t11riskfactorshadaexposure11isto巧ofmanycontactswithHCVinfec
