Hepatitis B virus concentrations in serum determined by sensitive quantitative assays in patients with established chronic hepatitis delta virus infection.

To clarify the correlation between hepatitis B virus (HBV) DNA levels and serum alanine aminotransferase (ALT) levels in patients with established chronic hepatitis delta virus (HDV) infection, sensitive HBV quantitative assays were used for the study. Thirty-four consecutive patients with chronic liver disease who were positive for both hepatitis B surface antigen (HBsAg) and antibody to HDV (anti-HDV), including 19 patients with chronic hepatitis, 8 patients with liver cirrhosis and 7 patients with hepatocellular carcinoma. All were negative for hepatitis Be antigen (HBeAg) and positive for antibody to HBeAg. HBV DNA was detected in 25 (73.5%) of the 34 patients using real-time detection PCR, and the HBV DNA levels of these patients were significantly lower compared with HBeAg status and ALT level-matched patients with chronic liver disease positive for HBsAg but negative for anti-HDV. There was no correlation between serum HBV DNA and ALT levels among the 34 patients with chronic liver disease positive for anti-HDV. Whereas serum ALT levels in anti-HDV-positive HBsAg carriers with HDV RNA were significantly higher than those without HDV RNA. Liver damage in patients with established chronic HDV infection may be caused mainly by ongoing HDV infection not by HBV replication.     

Cytokine patterns correlate with liver damage in patients with chronic hepatitis B and C

T-cell immunoregulatory cytokines influence the persistence of hepatitis C virus (HCV) chronic infection and the extent of liver damage. Th1 cytokines positively correlate with hepatic inflammation in chronic hepatitis B virus (HBV) infection. The pro-inflammatory, cytokines IL-6 and IL-18, are involved in viral clearance and in metabolic and viral hepatic diseases, respectively. The aim of this study was to evaluate the profile of Th1/Th2 cytokines in HCV and HBV hepatitis. HBV-infected patients showed higher plasma IFN-gamma levels than the HCV+ patients or the control group (p <0.0001). Plasma TNF-alpha and IL-2 were higher in HBV+ in comparison to HCV+ patients (p <0.001) or the control group (p <0.005). Plasma IL-6 and IL-18 were higher in both groups of patients compared to the control group (p <0.04). In HCV+ and HBV+ groups, IL-6 was positively correlated with the duration of the illness (p <0.01 and <0.001, respectively) and viral load (p <0.001 and <0.001, respectively), while IL-18 was positively correlated with serum ALT activity (p <0.01 and <0.001, respectively) and serum AST activity (p <0.01 and <0.001, respectively). We found that in HCV+ and HBV+ patients there are higher levels of Th1 cytokines, particularly in the course of chronic hepatitis B, and that IL-18 and IL-6 levels may have important roles as markers of both inflammation and hepatic injury, particularly in the course of hepatitis C.     

The degrees of hepatocyte cytoplasmic expression of hepatitis B core antigen correlate with histologic activity of liver disease in the young patients with chronic hepatitis B infection

Subcellular localizaton of HBcAg have been found to be related to the activity of liver disease and HBV replication. The aim of this study was to determine whether the degree of expression of HBcAg in the hepatocyte nucleus and cytoplasm reflects the level of viral replication and histological activity in chronic HBV infection. A total of 102 patients with biopsy proven chronic hepatitis B were included. There was a highly significant correlation between the levels of HBV DNA in serum and the degree of expression of HBcAg in the nucleus for HBeAg-positive(p=0.000) and negative patients(p=0.04). There was a highly significant, correlation between the degrees of expression of HBcAg in hepatocyte cytoplasm and histologic activities (p<0.01) for HBeAg-positive patients. The degrees of expression of HBcAg in the hepatocyte cytoplasm correlated positively with the lobular activities (p<0.01), but not correlated with the portal activity and fibrosis for HBeAg-negative patients. In conclusion, in the young patients with chronic B viral hepatitis, the degree of expression of HBcAg in the hepatocyte nucleus may affect viral load, and the degree of expression of HBcAg in the hepatocyte cytoplasm may affect histologic activities of liver disease.     

血清乙肝病毒外膜大蛋白检测及其与病毒复制的关系

慢性乙型肝炎患者血清和肝组织中HBV DNA含量与庚型肝炎病毒感染的关系

目的：观察慢性乙型肝炎（CH－B）患者血清、肝组织中HBV DNA含量与庚型肝炎病毒（HGV）感染的关系，探讨HGV感染对CH－B患者乙型肝炎病毒（HBV）复制的影响。方法：应用逆转录－聚合酶链反应（RT－PCR）、免疫组织化学法、荧光定量PCR（FQ－PCR）技术方法对56份CH－B患者血清HGV RNA、肝组织HGV Ag、血清及肝组织中HBV DNA含量分别进行了检测，并将血清HGV RNA与肝组织HGV Ag的表达、HGV RNA、HGV Ag阳性与阴性患者HBV DNA含量分别进行了对比研究。结果：血清HGV RNA、肝组织HGV Ag阳性分别为10份（17．9％）、8份（14．3％）。血清HGV RNA阳性与肝组织HGV Ag表达显著相关（P＜0．01），但部分肝组织HGV Ag阴性患者亦有血清HGV RNA表达。血清HGV RNA、肝组织HGV Ag阳性与阴性患者血清及肝组织中HBV DNA含量差异无显著性（P＞0．05）。结论：HGV感染对CH－B患者HBV复制无影响。HGV可在肝脏中复制，但致病性可能较微弱。

Symptomatic anti-HBe positive chronic hepatitis B in Taiwan with special reference to persistent HBV replication and HDV superinfection

Ninety-four patients, who were admitted with symptoms of liver disease and found to be positive for hepatitis B surface antigen and antibody to hepatitis B e antigen (anti-HBe), were examined for hepatitis B virus (HBV) DNA in serum and immunoglobulin antibody to hepatitis B core antigen and liver biopsies were stained for hepatic hepatitis B core antigen. Of 94 patients, 34 (36%) had evidence of HBV replication and 35 (37%) evidence of hepatitis D virus (HDV) superinfection. Most of the latter two groups of patients (greater than 70%) had evidence of chronic active hepatitis or active cirrhosis in their liver biopsies. The majority of these patients (greater than 80%) also had high levels of serum alanine aminotransferase (greater than 200 U/L) during the acute stage of their illness, and suffered from prolonged hepatic inflammation (greater than 1 year). Many of the patients (59%) also experienced frequent (1-6 episodes) relapsing exacerbations during a two-year follow-up period. Thus, persistent replication or reactivation of HBV and HDV superinfection were the two major causes of clinical exacerbations in anti-HBe-positive chronic HBV carriers in Taiwan, and also played an important role in the progression of their liver diseases and unfavorable outcomes.
