Background: Chronic Hepatitis B (CHB) entails an important
healthcare burden. The appropriate classification of CHB
patients regarding therapy requirements and prognosis often
requires a liver biopsy The aim of the study was to assess
the usefulness of new HBV biomarkers (qHBsAg, HBcrAg
and HBV-RNA) to predict clinical events in patients with CHB
Methods: Prospective study including 111 HBeAg-negative
patients: 74 naïve subjects with HBV DNA>2000 IU/mL
who underwent a liver biopsy and 37 CHB on nucleos(t)ide
analogues (NAs) with viral suppression for ≥2 years. Primary
endpoints were: treatment criteria in naïve patients (HBVDNA>
2000 IU/mL plus significant fibrosis in liver biopsy); and
HBsAg loss, development of hepatocellular carcinoma (HCC)
or liver decompensation for patients on NAs HBV-DNA was
quantified by qPCR (LLOD 20IU/mL), HBV-RNA by in-house
one-step RT-qPCR (LLOD 10 copies/mL) and HBcrAg by
chemiluminiscent enzyme immunoassay (LLOD 2 logU/mL)
Results: The majority were male and Caucasian, mean age
49 ± SD 14 years, 32% liver cirrhosis Among naïve patients,
20 (27%) met criteria for antiviral therapy throughout a median
follow-up of 10 8 months (IQR, 0 6-15 6 months) Baseline
biomarkers were higher among those who met treatment
criteria after liver biopsy: HBV-RNA (log cop/mL 2 61 vs
0 85, p<0 001), HBcrAg (logU/mL 3 81 vs 2 52, p<0 001),
HBV-DNA (logUI/mL 4 98 vs 3 93, p=0 001) and APRI
(0 58 vs 0 38, p=0 004) HBV-RNA presented the greatest
AUROC for identification of patients with criteria for antiviral
therapy (R=0 897) (Figure 1), followed by HBcrAg (R=0 785),
APRI (R=0 755) and HBV-DNA (R=0 748) The cut-off with
the highest Youden’s index was HBV-RNA>2.0 (Positive
predictive value=90%, Negative predictive value=95%)
Among NAs-virological suppressed patients, progressive
decrease of HBsAg (logUI/mL 2 75 vs 2 49, p=0 046), HBVRNA
(log cop/mL 0 74 vs 0 43, p=0 061) and improvement
of MELD score (8 7 vs 6 7, p<0 05) was observed when
comparing baseline and last follow-up results To date, 5
(14%) NAs-viral suppressed patients developed HCC All
presented liver cirrhosis, but only higher age (>50 years) and
AST (>40 UI/mL) at baseline were independent predictors
of HCC development (OR=4 5 and OR=10 5, respectively)
Conclusion: HBV-RNA is a useful non-invasive biomarker for
identification of naive HBeAg negative patients with significant
liver fibrosis who benefit from antiviral therapy. This marker
could avoid the performance of liver biopsy These results
need to be confirmed in a larger number of patients.

背景:慢性乙型肝炎(CHB)具有重要意義
醫療負擔。 CHB的適當分類
有關治療要求和預後的患者
需要進行肝活檢該研究的目的是評估
新的HBV生物標誌物(qHBsAg,HBcrAg
和HBV-RNA)來預測CHB患者的臨床事件
方法:前瞻性研究,包括111例HBeAg陰性
患者:74名初次接受HBV DNA> 2000 IU / mL的受試者
接受了肝活檢和核苷(t)的37 CHB的患者
具有≥2年病毒抑製作用的類似物(NAs)。主
終點是:初治患者的治療標準(HBVDNA>
2000 IU / mL加上肝活檢中明顯的纖維化);和
HBsAg丟失,肝細胞癌(HCC)的發展
NAs HBV-DNA患者的肝臟或肝代償失調為
通過qPCR定量(LLOD 20IU / mL),通過內部HBV-RNA定量
一步法RT-qPCR(LLOD 10拷貝/ mL)和HBcrAg通過
化學發光酶免疫法(LLOD 2 logU / mL)
結果:大多數為男性和白種人,平均年齡
49±SD 14歲,天真的患者肝硬化為32%,
在整個中位期間,有20名(27%)達到了抗病毒治療標準
隨訪10 8個月(IQR,0 6-15 6個月)基線
接受治療者中的生物標誌物較高
肝活檢後的標準:HBV-RNA(log cop / mL 2 61 vs
0 85,p <0 001),HBcrAg(logU / mL 3 81 vs 2 52,p <0 001),
HBV-DNA(logUI / mL 4 98 vs 3 93,p = 0 001)和APRI
(0 58 vs 0 38,p = 0 004)HBV-RNA表現最大
AUROC用於鑑定具有抗病毒標準的患者
治療(R = 0 897)(圖1),然後是HBcrAg(R = 0 785),
APRI(R = 0 755)和HBV-DNA(R = 0 748)與
尤登氏指數最高的是HBV-RNA> 2.0(陽性
預測值= 90%,負面預測值= 95%)
在NAs病毒學抑制的患者中,進行性
HBsAg降低(logUI / mL 2 75 vs 2 49,p = 0.046),HBVRNA
(log cop / mL 0 74 vs 0 43,p = 0 061)和改善
觀察到MELD得分(8 7 vs 6 7,p <0 05)
比較基線和最後隨訪結果迄今為止,5
(14%)NAs病毒抑制患者發展為HCC全部
表現為肝硬化,但年齡較大(> 50歲)且
基線時AST(> 40 UI / mL)是獨立的預測因子
肝癌發生率(OR = 4 5和OR = 10 5)
結論:HBV-RNA是一種有用的非侵入性生物標誌物,可用於
初次HBeAg陰性陰性患者的鑑別
肝纖維化誰受益於抗病毒治療。這個標記
可以避免肝活檢的表現
需要在更多的患者中得到證實。
