Early response to lamivudine therapy in clinically non-cirrhotic chronic hepatitis B patients with decompensation.

This study aimed to elucidate the rate and predictors of early (6 months) therapeutic responses to lamivudine, the rate of early mortality and the use of the model for end-stage liver disease (MELD) and Index in predicting the survival in patients with a clinical diagnosis of non-cirrhotic chronic hepatitis B with decompensation. Ninety-eight patients with lamivudine therapy were enrolled and MELD and Index scores were calculated. Surviving patients were treated with lamivudine for more than 6 months. Four (4.1%) of the 98 patients died after initiation of lamivudine therapy. After a 6-month lamivudine therapy, 80 (85.1%) patients and 71 (75.5%) patients had normal alanine aminotransferase (ALT) values and negative hepatitis B virus (HBV) DNA (<200 copies/mL), respectively, and hepatitis B e antigen (HBeAg)-negative patients had a significantly higher rate of negative HBV DNA than HBeAg-positive patients (P=0.002). The rates of HBeAg seroconversion and negative HBV DNA were 28.8 and 63.5%, respectively, and patients with HBeAg seroconversion had a significantly higher rate of negative HBV DNA (P=0.004). By multivariate analyses, older age, HBV nongenotype B infection, negative HBeAg and higher ALT levels were factors associated with negative HBV DNA, and a higher ALT level was associated with HBeAg seroconversion at month 6 after lamivudine therapy. MELD score and Index score were significantly associated with death and areas under the receiver operating characteristic curve for predicting survival were 0.936 and 0.907 respectively. We concluded that after 6-month lamivudine therapy, the patients who survived achieved favourable biochemical, virological responses and rate of HBeAg seroconversion. Both MELD and Index scoring systems are good models to predict the 6-month survival.

Baseline HBV DNA level is the most important factor associated with virologic breakthrough in chronic hepatitis B treated with lamivudine

AIM： To identify the factors associated with virologic breakthrough and to select a subgroup of patients who respond well to lamivudine without developing virologic breakthrough （VBT）.
METHODS： Of 79 patients who had received lamivudine therapy for 9-57 mo, 34 were HBeAg-positive and 45 were HBeAg-negative, 24 developed virologic breakthrough and 55 did not. Clinical and virologic factors were compared between the two groups.
RESULTS： The median duration of therapy was 25 （9-57） mo. Virologic breakthrough was defined as a 〉 1 log HBV DNA increase following initial suppression. When several factors, including gender, duration of infection, baseline HBV DNA, and baseline ALT in HBeAg-positive chronic hepatitis patients were analyzed by logistic regression, the most important predictor of virologic breakthrough was the baseline HBV DNA （r^2 = 0.12, P 〈 0.05）. When HBeAg-postitive chronic hepatitis patients were divided into two groups by a point of 6.6 log HBV DNA, the incidence of virologic breakthough between two groups was significantly different.
CONCLUSION： Lamivudine may remain an effective first line therapy for those HBeAg-positive patients with a baseline HBV DNA 〈 6.6 log10 copies/mL.

Diagnosis and treatment of chronic hepatitis B: an update

The diagnosis of chronic hepatitis B virus (HBV) infection is made using a combination of serological, virologic, biochemical, and histologic markers. The natural history of HBV infection can be divided into four phases: immune tolerance, immune clearance (HBeAg-positive chronic hepatitis B), inactive HBsAg carrier, and reactivation (HBeAg-negative chronic hepatitis B). Patients in the immune clearance and reactivation phases, with elevated alanine aminotransferase (ALT) and HBV DNA levels, are candidates for antiviral therapy. The primary goal of therapy for chronic hepatitis B is suppression of viral replication, which has been shown to reduce hepatic necroinflammation and retard progression of hepatic fibrosis. Long-term suppression of serum HBV DNA is likely to reduce progression to cirrhosis and hepatic decompensation and decrease the risk of hepatocellular carcinoma. Current antiviral therapy for chronic hepatitis B includes interferon alfa, peginterferon alfa-2a, lamivudine, adefovir, entecavir, and telbivudine. In patients with HBeAg-positive chronic hepatitis B, antiviral treatment is indicated when the serum HBV DNA level is = or > 10(5) copies/mL (20,000 IU/mL) and the ALT level is elevated. For HBeAg-negative patients, the threshold for initiation of therapy is lower, i.e., a serum HBV DNA level = or > 10(4) copies/mL (2,000 IU/mL) in association with an elevated ALT level. The presence of at least moderate necroinflammation and the presence of fibrosis on liver biopsy, which is optional and not mandatory before therapy, may be useful in supporting the decision to initiate therapy, particularly in patients with normal ALT levels. While undergoing therapy, patients require monitoring every 3 to 6 months to ensure compliance and to test for the development of resistance if an oral agent is used. Issues that remain controversial or need to be studied further are the necessity of a baseline liver biopsy, the HBV DNA and ALT thresholds for initiation of therapy, the optimal duration of antiviral therapy, selection of one agent over another, and the role of combination therapy.     

Dynamics of hepatitis B e antigen index ratio correlate with treatment response in chronic hepatitis B patients.

BACKGROUND/AIM: Hepatitis B e antigen (HBeAg) seroconversion is an important event in the natural history of chronic hepatitis B virus (HBV) infection. Whether early dynamics of HBeAg index ratio could predict therapeutic endpoint of HBeAg seroconversion in patients receiving lamivudine remains unclear and thus deserves investigation. METHODS: A total of 52 patients (males/females, 40/12; mean age, 31.1+/-7.5 years) with HBeAg-positive chronic hepatitis B and serum alanine aminotransferase (ALT) level > or = 5 x upper limit of normal were enrolled. They received daily 100 mg lamivudine for at least 1 year. Pretreatment HBeAg index ratio and the dynamics during treatment [early serologic response (ESR) and serologic breakthrough (SB)] between responders and non-responders were compared. RESULTS: Of these 52 patients, mean pretreatment serum ALT level was 580 IU/l and baseline HBeAg index ratio (S/N) was 37.9. The overall 1-year on-treatment combined response rate was 50%. By using linear regression analysis, HBeAg index ratio was positively correlated with serum HBV DNA level (Pearson's correlation coefficient: 0.62, P<0.0001). By using multivariate logistic regression analysis, ESR could predict the success of treatment response (P=0.0302), and SB had a 90% positive predictive value of treatment failure. CONCLUSIONS: HBeAg index ratio is closely correlated with serum HBV DNA level, and the dynamics of HBeAg index ratio may predict 1-year on-treatment combined response to lamivudine in HBeAg-positive chronic hepatitis B patients.
