Background: Hepatitis B is one of the most common infectious diseases in China, and it is necessary to study biochemical indicators of HBV infected patients.
Methods: Biochemical and basic features of 1765 HBV infected patients and 840 general controls were collected and analyzed from Southwest China.
Results: A total of 23.5% of the patients were children or young persons (less than 40 years old). The co-infected rate was only 0.3% for those who were co-infected with Hepatitis C virus (HCV) or Treponema pallidum (TPa). Most of patients (1081 individuals) were under convalescent condition, and 4.2% and 34.6% HBV patients were at acute and chronic phase, respectively. The indicators of liver function were significantly different between HBV patients and normal controls. In order to further study the variation of biochemical features in HBV patients in different phase, they were divided into three groups (sample #1: patients in acute infected phase; sample #2: patients in chronic infected phase; and sample #3: patients in convalescent condition). Excluding total protein and globin, all other indicators of liver function were statically different among the three groups. Total protein and albumin gradually decreased from convalescent patients, chronic HBV-infected patients, to acute HBV-infected patients.
Conclusions: Biochemical features could be used to evaluate the progress and therapeutic effects of HBV-infection. Our analysis firstly reported basic and biochemical information of HBV patients in Southwest China.
