Abstrakt:	Objective: To explore the impact of HBeAg positivity/negativity and HBV DNA loads on the prognosis of chronic severe hepatitis B. Methods: 206 patients with chronic severe hepatitis B hospitalized in Beijing Ditan Hospital from July 2002 to Dec. 2004 were analyzed. HBeAg positivity/negativity, HBV DNA loads and other factors relating to the prognosis of the patients were studied with univariate and multivariate analyses. Results: Chi2 univariate analysis showed that there was no significant difference in the prognosis between different HBeAg groups (chi2 = 0.440, OR = 0.777, 95% CI 0.424-1.425, P = 0.50). But there was a significant difference in the prognosis between different HBV DNA load groups: the prognosis of patients with lower HBV DNA loads was better than those with higher loads (chi2 = 9.806, OR = 3.055, 95% CI 1.554-6.007, P = 0.002), and the improving rates of the two groups were 53.1% and 27.0% respectively. Using multivariate logistic regression analysis, 9 screened factors showed great impact on the prognosis of chronic severe hepatitis B. Cirrhosis, hepatorenal syndrome, hepatic encephalopathy, PTA < 20%, TBil > 513 mmol/L, Alb < 30 g/L, CHO < 1.6 mmol/L, PLT < 5 x 10(9)/L, and higher HBV DNA loads (HBV DNA > 3 x 10(4) copies/ml in HBeAg negative patients and > 1 x 10(5) copies/ml in HBeAg positive patients) were shown to be associated with a poor prognosis. Coefficients of regression of the above factors were 1.539, 21.356, 1.398, 1.650, 2.440, 2.266, 1.738, 2.631 and 2.656 respectively. The coefficients of regression of HBV DNA loads were: B = 2.656, Wald = 7.768, P = 0.005, EXP(B) = 14.235, and 95.0% CI for EXP(B) = 2.199-92.133. Conclusions: Our results indicate that the HBV DNA loads were one of the most important factors influencing the prognosis of the chronic severe hepatitis B patients, the importance is only next to hepatorenal syndrome and over grade II hepatic encephalopathy. HBeAg positivity/negativity has no influence on the prognosis, but HBV DNA loads are important; the lower the viral loads, the better the prognosis.
