Background: five clinical phases were described in patients with chronic (HBV) infection: HBeAg- positive HBV infection, CHB, HBeAg negative HBeAg-negative CHB and occult infection.
 Aim: This study aimed to determine the incidence of unclassified phase (gray zone) hepatitis B its significant practice. 
 Patients methods: The was conducted retrospectively on 109 patients' who have HBs...

background to evaluate the strength of association and to determine the best prediction of response in terms of sensitivity and specificity among quantitative baseline hbv-dna levels in blood serum in patients with chronic hepatitis b (chb) infection who treated with interferon-alpha-2b. patients and methods totally, 78 chb patients with serum hbv-dna>105 copies/ml were treated with interferona...

BACKGROUND It is unclear whether hepatitis B e antigen (HBeAg) seroconversion induced by nucleos(t)ide analogues (NUC) has a prognosis that is similar to that of spontaneous HBeAg seroconversion. METHODS A total of 148 noncirrhotic NUC-induced HBeAg seroconverters were consecutively enrolled. A historical control of 407 noncirrhotic spontaneous HBeAg seroconverters was also recruited. We comp...

This study was performed to determine the factors for predicting the occurrence of acute exacerbation of hepatitis B virus infection in HBeAg-negative patients. Two hundred and sixteen patients with known times of HBeAg seroclearance were recruited. Liver biochemistry and virologic markers were monitored. Precore and core promoter mutations were determined by a line probe assay. The median age ...

BACKGROUND AND AIMS There is paucity of Indian data regarding serum HBsAg levels (qHBsAg) in treatment-naïve chronic hepatitis B (CHB). This study was done to determine correlation of qHBsAg with hepatitis B e antigen (HBeAg) and hepatitis B virus (HBV) DNA levels and its ability to independently categorize subgroups of CHB. METHODS We studied 131 treatment-naive CHB patients and initially cl...

T cell proliferative responses to hepatitis B virus-encoded envelope antigen (S + preS2 + preS1), recombinant core antigen (HBcAg), and natural hepatitis B e antigen (HBeAg) were examined in 22 HBeAg-positive patients with chronic type B hepatitis and 17 healthy hepatitis B surface antigen (HBsAg) carriers. The results showed that HBeAg-positive patients had (a) higher levels of T cell response...

BACKGROUND We studied whether hepatitis B surface antigen (HBsAg)/anti-HBs immune complex levels in chronic hepatitis B (CHB) patients receiving antiviral therapy could be used as a response marker at baseline (BL) or early during treatment to predict treatment outcome. METHODS An experimental array-based assay (immunological multi-parameter chip technology [IMPACT]; Roche Diagnostics, Penzbe...

HBeAg seroconversion is an important stage in the evolution of a chronic hepatitis B virus (HBV) infection that usually leads to control of viral replication and a reduced risk for liver cirrhosis and cancer. Since current therapies for the HBV-associated liver inflammation that is known as chronic hepatitis B (CHB). Rarely induce permanent HBeAg seroconversion, there is a need to understand th...
