The impact of HBeAg states and hepatitis B virus DNA loads on the prognosis of chronic severe hepatitis B / 中华传染病杂志

ABSTRACT

Objective To evaluate the impact of hepatitis B e antigen (HBeAg) states and hepatitis B virus DNA loads on the prognosis of chronic severe hepatitis B.Methods A total of 406 hospitalized patients with chronic severe hepatitis B in Nanfang Hospital of Southern Medical University from January 2002 to December 2007 were retrospectively analyzed.The impact of HBeAg states and HBV DNA loads on the prognosis was evaluated.The measurement data were compared by t test and rates were compared by chi square test.Results Of all the 406 patients with chronic severe hepatitis B,208 (51.2%) patients were HBeAg-positive and the remaining 198 (48.8%) were HBeAgnegative.There was no significant difference of constituent ratio of male and female,average peak value of total bilirubin and average valley value of prothrombin activity between HBeAg-positive group and HBeAgnegative group.However,the average age of HBeAg-negative patients was (46.7±12.8) years old,which was significantly higher than that (38.3±13.5) years old in HBeAg-positive group (t = 6.43,P＜0.01 )the proportion of patients with liver cirrhosis in HBeAg-negative group (67.7%) was much higher than that in HBeAg-positive group (45.7%) (X2=19.97,P＜0.01);the improved rate in HBeAg-negative group (32.3%) was significant lower than that in HBcAg-positive group (44.7%) (X2=6.56,P＜0.05).Increasing HBV DNA levels was associated with lower improved rate in both 208 HBeAg-positive and 198 HBeAg-negative patients(X2=22.98,26.04,respectively,both P＜0.01 ).Conclusions HBeAg-negative patients with chronic severe hepatitis B has worse prognosis than HBeAg-positive patients;and the prognosis is getting worse with the increasing HBV DNA level regardless of the HBeAg status.
