Outcome in Caucasian patients with hepatitis B e antigen negative chronic infection: A long-term observational cohort study

Sensitive polymerase chain reaction assays to measure hepatitis B virus (HBV) DNA became only available the last decade. Hence, the long-term outcome of Caucasian patients in Western Europe with hepatitis B e antigen (HBeAg)-negative chronic infection, especially with a baseline HBV DNA level ⩾2000 IU/mL, is still unclear. Out of a cohort of 1936 chronic HBV patients, 413 Caucasian individuals were identified with HBeAg-negative chronic infection, defined as persistently normal alanine aminotransferase (ALT) levels and HBV DNA levels <20 000 IU/mL. During a mean follow-up of 12 years, 366 (88.6%) maintained an HBeAg-negative chronic infection status, whereas 25 (6.1%) developed chronic active hepatitis (CAH). In total, Nine of these 25 CAH cases were related to immunosuppression. In total, 22 (5.3%) individuals had ALT > 2 × upper limit of normal due to non-HBV-related causes. The cumulative probability of spontaneously developing CAH after 10 years was almost exclusively seen in patients with baseline HBV DNA level ⩾2000 IU/mL (11.7% vs 1.2%; P < .001). Advanced liver disease developed significantly more in patients with baseline HBV DNA level ⩾2000 IU/mL (5.2% vs 1.5%; P = .018) and occurred especially in patients with obesity (16.7% vs 4.2%; P = .049). The incidence of hepatocellular carcinoma was 0.0%. Caucasian patients with HBeAg-negative chronic infection and baseline HBV DNA level <2000 IU/mL have an excellent long-term prognosis in the absence of immunosuppressive therapy. However, patients with baseline HBV DNA level ⩾2000 IU/mL are at risk to develop advanced liver disease.     

HBeAg阴性与阳性慢性乙型肝炎患者临床分析

目的观察乙肝病毒c抗原（HBeAg）阴性与阳性慢性乙型肝炎患者在年龄、ALT、乙肝病毒脱氧核糖核酸（HBVDNA）定量方面的特点。方法回顾性分析125例慢性乙型肝炎患者的临床资料,根据HBeAg表达情况分为HBeAg阴性与阳性慢性乙型肝炎两组,对两组患者的年龄、ALT和HBVDNA进行统计学分析。结果125例慢性乙型肝炎患者中,HBeAg阴性组24例,占19．2％;HBeAg阳性组101例,占80．8％。两组在平均年龄、HBVDNA之间比较,差异具有统计学意义;ALT之间比较没有统计学意义。在HBeAg阴性组中,HBVDNA定量较低,随着病毒载量的增高,ALT异常的数量呈下降趋势;在HBeAg阳性组中,HBVDNA定量较高,随着病毒载量的增高,ALT异常的数量大致呈上升趋势。结论HBeAg阴性慢性乙型肝炎患者年龄较HBeAg阳性患者高,ALT、HBVDNA定量水平低于HBeAg阳性者。随着病毒载量的增高,ALT异常的数量呈下降趋势,而后者则相反。     

慢性乙肝患者血清趋化因子RANTES水平与肝功能生化指标等的相关性研究

目的 了解慢性乙型肝炎(慢性乙肝)患者血清趋化因子RANTES水平,探讨血清RANTES水平与丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、总胆红素(TBil)、凝血酶原活动度(PTA)、乙型肝炎e抗原(HBeAg)及乙型肝炎病毒(HBV DNA)载量的相关性.方法 选择144例慢性乙肝患者(观察组)和18名健康人(对照组),采取静脉血并应用ABC-ELISA方法 检测其血清中趋化因子RANTES浓度,并与两组的肝功能检测生化指标、HBeAg和HBV DNA载量进行相关性分析,利用SPSS13.0软件进行统计分析.结果 慢性乙肝患者血清RANTES的浓度比正常对照组升高,血清RANTES浓度分别为(3930.12±2856.96)ng/ml和(329.46±152.23)ng/ml,两组之间差异比较均有统计学意义(P<0.05);RANTES水平与ALT(r=0.197,P:0.018)、AST(r=0.239,P=0.004)和Tnil(r=0.316,P=0.001)呈显著正相关;RANTES水平与PTA(r=-0.078,P=0.357)无显著相关;HBeAg阴性组与HBeAg阳性RANTES水平比较无统计学意义(P=0.407);HBV DNA低载量组(<105拷贝/ml)和HBVDNA高载量组(≥105拷贝/ml)RANTES水平比较无统计学意义(P=0.185).结论 慢性乙肝患者血清中RANTES表达水平增高,血清RANTES水平与ALT、AST和TBIL呈正相关,与PTA无相关性.RANTES水平可反映肝脏炎症活动及损害情况,不受HBeAg、HBV DNA载量影响,可能参与慢性乙肝发病.     

Serum hepatitis B virus (HBV) DNA levels at different stages of clinical course in patients with chronic HBV infection in an endemic area

The aims of this study were to investigate serum hepatitis B virus (HBV) DNA levels at different clinical stages in patients with chronic HBV infection, and to determine the serum HBV DNA level that discriminated HBeAg-negative chronic hepatitis B(CHB) cases from inactive HBsAg carriers. In all, 222 patients, encompassing 68 HBeAg-positive CHB patients (HBeAg-positive, ALT-elevation), 89 HBeAg-negative CHB patients (HBeAg-negative, ALT-elevation), and 65 inactive HBsAg carriers (HBeAg-negative, ALT-normal), were tested. The ALT levels had been tested more than twice during the previous six months, and the serum HBV DNA levels were quantified by a polymerase chain reaction-based assay. The serum HBV DNA levels of the HBeAg-negative patients were significantly lower than those of the HBeAg-positive patients (median 2.7 x 10(4) vs. 1.6 x 10(8) copies/mL; p=0.000). In addition, the HBV DNA levels of the HBeAg-negative CHB patients were significantly higher than those of the inactive HBsAg carriers (median 2.2 x 10(5) vs. 3.2 x 10(3) copies/ mL; p=0.000). The optimal HBV DNA level for discriminating HBeAg-negative CHB cases from inactive HBsAg carriers was 2.0 x 10(4) copies/mL. The serum HBV DNA levels were lower than the cutoff value in 72.3% (47/65) of the inactive HBsAg carriers, and in 31.5% (28/89) of the HBeAg-negative CHB patients. The serum HBV DNA levels differed significantly between these two groups. However, the levels in the two groups overlapped extensively, preventing the definition of a differentiation cut-off value.     

Identification of different states of hepatitis B virus infection with a quantitative PCR assay

The level of hepatitis B virus (HBV) DNA in serum reflects the replicative activity of HBV. To compare serum HBV DNA levels in different states of hepatitis B, 47 sera of patients with HBeAg-positive chronic hepatitis B, 4 sera of patients with HBeAg-negative chronic hepatitis B, 40 samples of patients after HBeAg seroconversion during alpha interferon treatment, 57 sera of inactive HBsAg carriers, and 42 sera of patients who had recovered from chronic hepatitis B more than 12 months prior to blood collection were checked for the presence of HBV DNA with the Amplicor HBV Monitor Test. In patients with HBeAg-positive chronic hepatitis B, the median of serum HBV DNA levels (8.3 x 10(8) copies/ml) was significantly higher than that for patients after HBeAg seroconversion (6.2 x 10(3) copies/ml) and than that for inactive HBsAg carriers (5.6 x 10(3) copies/ml). None of the patients who had recovered from hepatitis B had detectable HBV DNA in serum. Quantitative PCR proved to be a valuable tool for identification of different states of HBV infection. This technique was found to be a good method for determination of serum HBV DNA levels both for patients with HBeAg seroconversion and for inactive carriers who showed low viremia not detectable by conventional hybridization assays.     

Detection of hepatitis B viral DNA by polymerase chain reaction in patients with hepatitis B surface antigen

Hepatitis B virus (HBV) DNA was assayed using the polymerase chain reaction in serum samples of 116 hepatitis B surface antigen (HBsAg) carriers, including 30 positive for hepatitis B e antigen (HBeAg) and 86 negative for HBeAg. In the HBeAg-positive group, all were positive for HBV DNA. In the HBeAg-negative group, 80.2% were positive for HBV DNA (80.0% in the healthy carrier group, 90.0% in the chronic active liver disease group, and 69.2% in patients with cirrhosis). This study indicated that every HBeAg-positive carrier as well as the majority of HBeAg-negative carriers were infectious and, in the latter group, that viral replication is most active in patients with chronic active liver disease.     

Serum hepatitis B surface antigen levels correlate with high serum HBV DNA levels in patients with chronic hepatitis B: a cross-sectional study

Purpose: The hallmark of chronic hepatitis B (CHB) infection is the presence of hepatitis B surface antigen (HBsAg) positivity for at least 6 months. Recently, serum levels of HBsAg have been compared with serum HBV DNA as a surrogate marker to monitor CHB patients. However, data correlating these two markers are scarce. Hence, the present study was done to correlate HBV DNA with HBsAg in CHB patients. Materials and Methods: Consecutive patients of CHB were included. HBV DNA was measured by real-time polymerase chain reaction (PCR). Serum HBsAg was measured by Architect HBsAg. Results: Of the 198 patients enrolled, 166 fulfilled the inclusion criteria (mean age 43 ± 14 years, 87% males) and the median HBV DNA was 1.7 × 10³ (range 6.0–1.1 × 10⁸) IU/ml. Median HBsAg was 8.7 × 10³ (range 5.0–3.2 × 10⁵) IU/ml. Overall correlation between HBV DNA and HBsAg was weak but significant (Spearman ρ = 0.443, P < 0.01). Correlation in HBe antigen-positive group was better (ρ = 0.402, P < 0.01) in comparison to HBe antigen-negative group (ρ = 0.193 P = 0.05). Good correlation existed in treatment-naïve group (ρ = 0.538, P < 0.01). Correlation was regardless of normal or raised alanine transaminase (ALT). Eighty (48%) patients had high HBV DNA (≥2000 IU/ml). Correlation in high DNA group was significant (P < 0.01). The best cut-off of HBsAg for diagnosing high DNA is 3.36 ×10³ IU/ml. Conclusions: Serum HBsAg correlates with HBV DNA in CHB patients, especially in high serum HBV DNA, HBe antigen-positive and treatment-naïve group. HBsAg levels can be used for predicting high serum HBV DNA levels.

Clinical implications of serum hepatitis B virus RNA quantitation in untreated chronic hepatitis B virus-infected patients

Serum hepatitis B virus (HBV) RNA quantitation may be useful for managing untreated chronic HBV-infected patients, but its distribution characteristics and relationship to HBV DNA are unclear. A retrospective cohort including 149 untreated HBV-infected patients was divided into four clinical phenotypes: hepatitis B envelope antigen (HBeAg) positive with normal alanine transaminase (ALT; EPNA) or with elevated ALT (EPEA), HBeAg-negative with normal ALT (ENNA) or with elevated ALT (ENEA). Serum HBV RNA levels were quantified by a high-sensitivity real-time fluorescent quantitative PCR method and liver biopsy was performed in those with undetectable serum HBV DNA or RNA. The detectable serum HBV RNA levels (log₁₀ copies/mL) in EPNA, EPEA, ENNA, and ENEA were 6.02±1.48, 6.54±1.27, 2.51±0.78 and 3.54±1.25, respectively. The low level (< 2.0 log₁₀ copies/mL) comprised mainly of ENNA phenotype (76.9%), while the high level (> 6.0 log₁₀ copies/mL) was HBeAg-positive patients (98.1%). Serum HBV RNA level were significantly correlated with serum HBV DNA and HBsAg in HBeAg-positive phenotypes, but a correlation only with HBV DNA was observed in ENEA patients. Serum HBV DNA and RNA were both independent risk factors associated with elevated ALT in HBeAg-negative patients. Seven serum HBV DNA-undetectable but RNA-detectable patients underwent liver biopsy, showing moderate or severe liver inflammation. Varying serum HBV RNA levels can reflect natural disease phases in untreated HBV-infected patients, indicating that this biomarker could reflect liver inflammation in untreated HBeAg-negative patients as successfully as serum HBV DNA. Serum HBV RNA can complement clinical management strategies when serum HBV DNA is undetectable.
