摘要:
SummaryThe mode of contamination, presentation, clinical evolution and liver histology of 10 native Belgian patients with chronic hepatitis B likely due to a peculiar viral strain, the so called precorc mutant hepatitis B virus were reviewed. This viral strain first described in Southern European regions is characterizxd by a mutation of a single base change at nucleotide 1896 in the preterminal codon of the precore region which creates a stop codon that prevents the production of HBeAg. In this setting, abnormal liver biochemistry and active viral replication as evidenced by IIBV DNA positivity often coincides with a serological profile similar to that observed in healthy HBsAg carriers. Our data indicate that chronic hepatitis related to such a viral strain may be observed in a native Belgian population. This unusual presentation of chronic hepatitis B should thus be kept in mind when interpreting atypical sero-biochemical features, evaluating the risk of infectivity and the potential benefit of antiviral therapy.
