Abstract

BACKGROUND AND STUDY AIMS:

We aimed to evaluate the therapeutic efficacy of pegylated interferon alpha-2a 180μg as a treatment for hepatitis B 'e' antigen (HBeAg)-positive genotype D chronic hepatitis B patients.

PATIENTS AND METHODS:

Thirty patients attending the outpatient clinic at the National Hepatology and Tropical Medicine Research Institute were treated with peg.interferon alpha-2a (180μg) weekly for a period of 48 weeks. Pre-enrolment assessment was performed through biochemical, serological and quantitative HBV DNA testing. Liver biopsy was performed in all patients. Evaluation was done at weeks 12, 24 and 48 of treatment by liver enzymes, complete blood count (CBC), HBeAg/HBeAb and quantitative HBV DNA testing.

RESULTS:

At the end of 48 weeks of treatment only three cases (10%) of the study population showed HBeAg seroconversion and an undetectable HBV DNA level. None of responders exhibited hepatitis B surface antigen (HbsAg) loss. There were five (16.7%) primary non-responders, four (13.3%) relapsers, four (13.3%) cases flared at week 12, and 14 (46.6%) cases who were non-responders. No specific predictors of response could be identified among patients.

CONCLUSION:

One year of peg. interferon alpha-2a 180μg weekly led to HBeAg seroconversion and an undetectable HBV DNA level in 10% of cases. Considering the privilege of a finite duration of treatment, tailoring of treatment and proper patient selection is of great importance in considering this therapy as a first line of treatment among HBeAg-positive chronic HBV Egyptian patients.
