Abstract

We read with great interest the article entitled "HBV RNA profiles in chronic hepatitis B patients under different disease phases and anti-viral therapy" authored by Mak et al(1). The authors proposed that the reverse transcription efficiency in HBeAg-positive patients was significantly higher than that in HBeAg-negative patients, based on the RNA: DNA ratio in the two groups of patients (0.79 vs. 0.53; p< 0.001). We had found that a higher ratio of serum HBV RNA to HBV DNA was inversely related with reverse transcription efficiency of HBV pgRNA(2), and HBeAg-positive patients had a lower reverse transcription efficiency of HBV pgRNA than HBeAg-negative patients did. We here suggest that the ratio of serum HBV DNA: (HBV DNA + HBV RNA) is more reliable to assess the reverse transcriptional efficiency of pgRNA. The medians of ratio in our cohort were 0.56 (n = 54), 0.56 (n = 23), 0.69 (n = 64) and 0.66 (n = 4), for patients with HBeAg-positive chronic infection, HBeAg-positive chronic hepatitis, HBeAg-negative chronic infection, and HBeAg-negative chronic hepatitis, respectively. Inconsistent with the report by Mak et al., our data showed that the reverse transcriptional efficiency was lower in HBeAg-positive patients than in HBeAg-negative patients (0.56 vs. 0.68; p< 0.001). A schematic diagram for illustrating the efficiencies of covalently closed circular DNA (cccDNA) transcription and reverse transcription of pgRNA are shown in Figure 1.

抽象的

我们非常感兴趣地阅读了由Mak等(1)撰写的题为“慢性乙型肝炎患者在不同疾病阶段和抗病毒治疗下的HBV RNA谱”的文章。作者提出,基于两组患者的RNA:DNA比率,HBeAg阳性患者的逆转录效率显着高于HBeAg阴性患者(0.79 vs. 0.53; p <0.001)。我们发现,血清HBV RNA与HBV DNA的比例较高与HBV pgRNA的逆转录效率呈负相关(2),并且HBeAg阳性患者的HBV pgRNA的逆转录效率低于HBeAg阴性患者。我们在这里建议血清HBV DNA:(HBV DNA + HBV RNA)的比率对于评估pgRNA的逆转录效率更为可靠。对于HBeAg阳性慢性感染,HBeAg阳性慢性肝炎患者,我们队列的比率中位数分别为0.56(n = 54),0.56(n = 23),0.69(n = 64)和0.66(n = 4)。 ,HBeAg阴性慢性感染和HBeAg阴性慢性肝炎。与Mak等人的报告不一致,我们的数据表明,HBeAg阳性患者的逆转录效率低于HBeAg阴性患者(0.56比0.68; p <0.001)。图1显示了共价闭合环状DNA(cccDNA)转录和pgRNA逆转录效率的示意图。
