Factors related to the outcome of patients with chronic severe hepatitis B and effectiveness of antivirus therapy / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To investigate the factors related to the outcome of patients with chronic severe hepatitis B and effectiveness of antivirus therapy.</p><p><b>METHODS</b>The effects of the factors including age, prothrombin activity (PTA), serum HBeAg, Anti-HBe, HBV-DNA load, with or without complication, antivirus therapy and so on, on outcome of 330 patients with chronic severe hepatitis B were analyzed in this retrospective study.</p><p><b>RESULTS</b>The mortality of patients with chronic severe hepatitis B was significantly higher among patients at higher age, with lower PTA, and with more complications. The mortality of patients with HBV-DNA more than 1x10(5) copies/ml (52.3 percent) was higher than that of patients whose HBV-DNA was less than 1x10(5) copies/ml (32.9 percent). There was no correlation between serum HBeAg or anti-HBe and the mortality. The mortality of patients with HBV-DNA higher than 1x10(5) copies/ml (30.38 percent) who were treated with lamivudine in 2005 was lower than that of patients whose HBV-DNA was less than 1x10(5) copies/ml (54.64 percent) who were not treated with any antiviral therapy in 2001.</p><p><b>CONCLUSION</b>The higher serum virus load is the key factors of the mortality in addition to the other factors such as older age, lower PTA, more complication in the patients with chronic severe hepatitis B. The usage of antivirus therapy may be associated with lower mortality.</p>

Virological, serological and clinical characteristics of anti-HBc IgM positive chronic hepatitis B patients / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To investigate the clinical characteristics of anti-HBc IgM positive chronic hepatitis B patients and the relation of anti-HBc IgM development to serum HBV DNA load and the state of HBeAg/anti-HBe.</p><p><b>METHODS</b>The clinical data were collected from patients with chronic hepatitis B hospitalized in the Infectious Diseases Hospital, Zhangjiakou city, and in Ditan Hospital, some of whom were anti-HBc IgM positive and some others were negative. Their HBV DNA load was examined by real-time PCR, and HBeAg/anti-HBe was detected by AXSYM auto-enzyme analyzer with the third generation EIA regent.</p><p><b>RESULTS</b>Totally 200 patients were enrolled in this study. The number of patients with mild, moderate and severe hepatitis was 71, 83 and 46. The anti-HBc IgM positive patients were older and had longer course of disease than those of anti-HBc IgM negative patients. Of the anti-HBc IgM positive group, 45.71 percent and 54.29 percent had mild and moderate hepatitis, which were significantly different from those in the anti-HBc IgM negative patients (30.00 percent and 70.00 percent). But there was no difference between anti-HBc IgM positive and negative patients in serum HBV DNA level, the state of HBeAg/anti-HBe and outcome.</p><p><b>CONCLUSION</b>The anti-HBc IgM state of chronic hepatitis B patients was related to the severity of hepatitis, but not with virus load and state of HBeAg/anti-HBe.</p>
