【摘要】 目的:探讨HCV-cAg在丙型肝炎中的诊断价值。方法:选取2017年2月-2019年2月于本院就诊的72例疑似丙型肝炎患者为研究对象。采用实时荧光定量PCR法检测HCV-RNA水平,分析HCV-RNA与HCV-cAg的检测结果,HCV-RNA不同载血量血清的HCV-cAg阳性率。结果:HCV-cAg检测的准确度88.9%(64/72),特异度92.7%(38/41),灵敏度83.9%(26/31)。HCV-RNA载血量血清数值<103 IU/mL、≥103 IU/mL且<104 IU/mL、≥104 IU/mL且<105 IU/mL、≥105 IU/mL且<106 IU/mL、>106 IU/mL患者的HCV-cAg阳性率分别為4.9%、75.0%、83.3%、91.7%、100%。结论:HCV-cAg诊断丙型肝炎的准确度、特异度及灵敏度均较高,HCV-RNA载血量血清数值越大,HCV-cAg阳性率越高,因此HCV-cAg的检测可作为HCV-RNA的补充检测,临床应用价值较高。

Diagnostic Value of HCV-cAg in Hepatitis C/SUN Jian. //Medical Innovation of China, 2021, 18(05): -110

[Abstract] Objective: To explore the diagnostic value of HCV-cAg in hepatitis C. Method: A total of 72 suspected hepatitis C patients admitted to our hospital from February 2017 to February 2019 were selected as the research subjects. The level of HCV-RNA was detected by real-time fluorescence quantitative PCR, and the detection results of HCV-RNA and HCV-CAG were analyzed, the positive rate of HCV-CAG in serum with different blood loads of HCV-RNA was analyzed. Result: The accuracy, specificity, and sensitivity of HCV-cAg detection were 88.9% (64/72), 92.7% (38/41), 83.9% (26/31). The positive rates of HCV-cAg were 4.9%, 75.0%, 83.3%, 91.7%, 100% in patients with HCV-RNA blood load and serum value <103 IU/mL, ≥103 IU/mL and <104 IU/mL, ≥104 IU/mL and <105 IU/mL, ≥105 IU/mL and <106 IU/mL, >106 IU/mL, respectively, the higher the serum value of HCV-RNA blood load. Conclusion: The accuracy, specificity and sensitivity of HCV-cAg in the diagnosis of hepatitis C are high, the higher the serum value of HCV-cAg blood carrying volume, the higher the positive rate of HCV-cAg, therefore, the detection of HCV-cAg can be used as a supplementary detection of HCV-RNA, its clinical application value is high.

丙型肝炎为全球范围内传染性疾病,临床数据显示丙型肝炎发病率出现逐年上升趋势,该病感染率较高,约为3%[1]。丙型肝炎是一种经血液传播丙型肝炎病毒性疾病,慢性化为该病主要临床特征,该病危害性较大,随病情加重会进一步发展为肝细胞癌,对患者身体健康产生较大威胁,降低了患者生活质量,影响了正常生活和工作[2]。当前没有针对性疫苗,因此早期治疗和诊断非常重要,HCV-cAg检测可有效缩短窗口期,探究HCV-cAg的诊断价值具有非常重要的作用[3]。HCV-cAg检测对感染患者病情监控具有较好的预测作用,另外与抗原抗体复合物结合,可为患者临床治疗提供有效理论依据和临床治疗,有利于患者尽早发现疾病和改善症状[4]。该研究围绕HCV-cAg在丙型肝炎中的诊断价值,旨在为临床提供有效指导,现报道如下。
