A Prospective Study of Therapeutic Effect of 6 Months Trial with Lamivudine
in Patients with Chronic Viral Hepatitis B
Abstract
- BACKGROUND/AIMS
The purpose of this study was to evaluate the effectiveness
of lamivudine treatment in patients with chronic liver disease caused by chronic infection
of hepatitis B virus (HBV).
METHODS
Thirty-ive patients with chronic infection of HBV were included in this study who
were diagnosed at Hanyang University Hospital from January 1998 to January 1999.
They received 150mg of lamivudine per oral once daily for 6 months with follow-p
of liver function test, serum HBV DNA and serologic markers for hepatitis B virus
every two months. Lamivudine was well tolerated. Eight patients underwent liver
biopsies before entering the study and follow-p biopsies were done at 5 patients.
RESULTS
Out of all 35 patients, chronic hepatitis patients histologically confirmed
were 8, chronic hepatitis patients clinically diagnosed were 25 and liver cirrhosis
patients clinically diagnosed were 2. The mean age was 35.7 years. Male-female ratio
was 2.2:1. There was no hepatitis B surface antigen (HBsAg) negative seroconversion.
The HBeAg loss rate was 26.9%(7/26) and HBeAg seroconversion rate was 10.7%(3/28)
at the end of follow-p. Ten patients were anti-Be positive prior to treatment,
3 of them became anti-Be negative at the end of follow-p. Five patients underwent
follow-p liver biopsies, in which histologic improvements were shown in 4 cases.
Serum replicative HBV DNA by bDNA assay was decreased in all patients and HBV DNA
was undetectable in 52.9%(9/17) at the end of treatment. Out of the 15 patients
with abnormal alanine aminotransferase (ALT) levels at baseline, ALT level
in 7 patients(46.7%) was normalized at treatment completion. Pretherapy ALT level
was the only predictive factor for loss of HBeAg by stepwise logistic regression
analysis(odds ratio : 1.0208) (95% Confidence Interval : 1.0023 ~ 1.0396) (p value=0.0271).
CONCLUSIONS
Lamivudine induced sustained suppression of HBV replication during treatment
in all patients. In treating patients with lamivudine, who had chronic liver disease due to
chronic infection of HBV, the improvement of liver function test and suppression of
viral replication appeared early and was sustained during the 6months treatment.
This, in turn, may induce histological improvement as well. Pretherapy ALT level
was the only predictive determinant for HBeAg loss during lamivudine therapy,
and that should be kept in mind in selecting patients for treatment.
