ABSTRACT
<p><b>OBJECTIVE</b>To analyze the information of the supplementary card for hepatitis B and the laboratory confirmed result of immunoglobulin M antibody to hepatitis B virus (HBV) Core Antigen (anti-HBc IgM) for the suspected acute hepatitis B to evaluate the hepatitis B report data on pilot surveillance.</p><p><b>METHODS</b>200 counties were established in China for hepatitis B pilot surveillance and 63 641 cases were reported. We added a supplementary card in National Notificable Disease Reporting System (NNDRS) and all the reported hepatitis B cases in NNDRS were required to fill the supplementary card. Venous blood 5 ml was collected and a confirmed test of anti-HBc IgM was made for suspected acute hepatitis B. We made confirmed diagnosis for the suspected acute hepatitis B according to the supplementary card information of the reporting card and the confirmed test result of anti-HBc IgM.</p><p><b>RESULTS</b>63 641 hepatitis B cases were reported in 200 hepatitis B pilot surveillance counties in 2013. Among 1 723 cases which were filled with the HBsAg positive within six months in supplementary card, 735 cases were reported as chronic hepatitis B, the proportion was 42.66%. Among 4 582 cases which were filled with anti-HBc IgM positive in supplementary card, 2 436 cases were reported as acute hepatitis B, the proportion was 53.16%. 1 829 cases were reported as chronic hepatitis B, the proportion was 39.92%. The validity cases of the information for liver puncture and the HBV surface antigen (HBsAg) transform during the recovery period in supplementary cards for all the reporting cases were 579 and 4 961, and the rate were 0.91% and 7.80%, respectively. 4 302 suspected acute cases were made confirmed diagnosis, and 1 197 cases (27.82%) were confirmed acute and 2 590 cases (60.20%) were confirmed chronic.</p><p><b>CONCLUSION</b>Clinical doctors failed to make full use of the information of supplementary cards to make classification diagnose for hepatitis B. Suspected acute hepatitis B with anti-HBc IgM positive should be pay attention to follow up and further distinguish acute or chronic hepatitis B according to the HBsAg transform.</p>
