Controversies exist regarding the classification of the different clinical phases of chronic hepatitis B (CHB) because hepatitis B virus (HBV) DNA and alanine aminotransferase levels fluctuate over time.1,2 To improve the distinction of clinical phases and the associated spectrum of clinical outcome,3,4 hepatitis B surface antigen (HBsAg) levels may be of help.5–7 We hypothesize that HBV genotype specific HBsAg levels are needed for the identification of different clinical HBV disease phases.7

Additional support was provided by Gilead Sciences, Inc. and Roche Molecular Systems via a CRADA through the NIDDK. The NIDDK (NIH) provided financial support for each of the clinical centers and a data coordinating center though a cooperative agreement. NIDDK project officers and scientists participate in meetings of the network investigators and offer suggestions on data analysis. The funding source did not have influence on analysis and interpretation of the data, writing of the report or the decision to submit for publication.
