Etiological Investigation of Fatal Liver Failure During the Course of Chronic Hepatitis B in Southeast China
Overview
Affiliations
Background: The purpose of this study was to clarify the relationships between patients who had fatal liver failure during the course of chronic hepatitis B and those who were also superinfected with hepatitis A, C, D, or E virus, as well as their hepatitis B virus e system status, so that suitable measures could be adopted to decrease the mortality of patients with chronic hepatitis B.
Methods: This study detected superinfections of hepatitis A, C, D, or E virus and the hepatitis B virus e system status in cases of fatal liver failure during the course of chronic hepatitis B by enzyme-lined immunosorbent assay.
Results: The frequency of superinfections of hepatitis A, C, D, and E virus was 1.4% (4/282), 6.4% (18/282), 1.8% (5/282), and 28.4% (80/282), respectively, overall, 37.9% (107/282). Hepatitis E was prominent and steady in superinfection rates during the past 12 years. In 62.1% (175/282) of patients, the causes of fatal liver failure were not clear. The serological status frequency of HBeAg(+) and anti-HBe(-), HBeAg(-) and anti-HBe(-), and HBeAg(-) and anti-HBe(+) was 20.6% (22/107), 23.4% (25/107), and 56.1% (60/107), respectively, in the group with superinfections of hepatitis A, C, D, or E virus and 31.4% (55/175), 21.1% (37/175), and 47.4% (83/175), respectively, in the group in which causes were not clear. The serological status HBeAg(+) and anti-HBe(-) was more frequent in the group in which causes were not clear than in the group with superinfections of hepatitis A, C, D, or E virus (P < 0.05). Statistically, there were no differences (P > 0.05) between the serological status HBeAg(-), anti-HBe(-) and HBeAg(-), anti-HBe(+) between the two groups.
Conclusions: These results suggest that superinfection (107/282) is an important factor in fatal liver failure. The mortality of chronic hepatitis B can be decreased by strict food sanitation and the use of safe blood products. There were no significant relationships between hepatitis B e antigen seroconversion and fatal liver failure during the course of chronic hepatitis B.
