摘　　要：目的比较RACE法和Sansure法检测核苷(酸)类似物经治和初治慢性乙型肝炎患者HBV RNA定量值的相关性和一致性。方法纳入南方医科大学南方医院门诊随访的慢性乙型肝炎患者并收集患者血清学、病毒学和生化数据。采集患者血清分别用RACE法和Sansure法检测HBV RNA水平,分析两者检测值的相关性和一致性。结果共入组101例慢性乙型肝炎患者,其中接受核苷(酸)类似物治疗62例,未曾接受核苷(酸)类似物治疗39例。治疗和未治疗组的HBsAg和HBV DNA水平存在显著差异,HBV RNA水平差异有统计学意义。两种方法相比,RACE法比Sansure法检测到的阳性患者更多(60/101和56/101),平均检测值更高(3.16和2.53 lg拷贝/mL)。HBV DNA水平与HBV RNA水平在治疗组没有相关性(RACE法R^2=0.4406,Sansure法R^2=0.5081),在未治疗组显著相关(RACE法R^2=0.8448,Sansure法R^2=0.8667)。RACE法和Sansure法HBV RNA检测值显著相关(R^2=0.8740);此外,两种HBV RNA检测方法Bland-Altman分析显示,95%一致性界限的范围较窄(在治疗组为-1.789~0.22 lg拷贝/mL,在未治疗组为-2.25~0.53 lg拷贝/mL);以RACE法为基准,Sansure法的偏差在治疗组为-0.78 lg拷贝/mL,在未治疗组为-0.86 lg拷贝/mL。两种方法线性回归后方程:Y(Sansure法)=0.9189X(RACE法)-0.3754。结论两种HBV RNA检测方法的相关性显著,一致性较好,可用线性回归方程互算;两种HBV RNA检测方法均可有效弥补血清HBV DNA检测对指导慢性乙型肝炎临床诊治方面的不足。Objective To compare Race method and Sansure method in HBV RNA quantification in naive and treated patients with chronic hepatitis B(CHB).Methods Clinical datas were collected from patients who were followed up in the outpatient department of Nanfang Hospital.RACE method and Sansure method were used to detect patients'serum HBV RNA levels.The correlation and consistency of the two assays were analyzed.Results A total of 101 patients were enrolled,including 62 patients who received nucleoside/nucleotide analogues(NAs)treatment and 39 patients who did not receive any NAs treatment(i.e.,na?ve patients).There were significant differences in HBsAg and HBV DNA levels between the treated and untreated groups.There were statistically differences in serum HBV RNA levels in the two groups.Detectable serum HBV RNA was seen in more patients in RACE group than in Sansure group,as well as higher mean levels of serum HBV RNA(3.16 lg copies/mL vs 2.53 lg copies/mL).There was no significant correlation between HBV DNA levels and HBV RNA levels in the treatment group(RACE R^2=0.4406,Sansure R^2=0.5081);while in the untreated group,there has significant correlation between the two methods(Race R^2=0.8448,Sansure R^2=0.8667).RACE and Sansure were significantly correlated in detectable HBV RNA levels(R^2=0.93498740,P<0.001).In addition,Bland-Altman analysis showed that the 95%of agreement of the two HBV RNA detection methods was relatively narrow(-1.789~0.22 lg copies/mL in the treatment group,and-2.25~0.53 lg copies/mL in the untreated group).If RACE method was used as the baseline,the deviation of Sansure method was-0.78 lg拷贝/mL in the treatment group and-0.86 lg拷贝/mL in the untreated group.Linear regression equation:Y(Sansure)=0.9189X(RACE)-0.3754.Conclusion The correlation between the two methods is significant and can be calculated by linear regression equation;Both the two HBV RNA detection methods can effectively make up for the deficiency of serum HBV DNA detection in guiding the clinical diagnosis and treatment of CH
