Clinical utility of hepatitis B surface antigen levels during the natural history and treatment of chronic hepatitis B infection

THE SERUMAL CONCENTRATION OF HBSAG IN PATIETS WITH CHB/HIV CO-INFECTION COMPARING WITH CHB MONO-INFECTION IN THE DIFFERENT PHASES OF NATURAL COURSE OF CHRONIC HEPATITIS В

The prevalence and inclination to chronization of viral hepatitis B is 3 – 5 times higher in patients with HIV-infection than in HIV-negative ones. The natural clinical course of chronic hepatitis B (CHB) in patients with HIV has the features, connected with immune suppression and mutual influence of viruses. The quantitative determination of HBsAg allows the more precise monitoring of the natural course and the dynamics of treatment of patients with CHB but these features are little studied in patients with co-infection CHB/HIV. In the work was presented the comparative analysis of the results of quantitative determination of the serumal HBsAg in 59 Patients with co-infection CHB/HIV and 60 ones with chronic hepatitis. At the study it was established, that in patients with CHB/HIV co-infection were observed the reliably higher qHBsAg levels than in HIV-negative ones both in whole and in each CHB phase that depends on the immune suppression degree and DNA level of hepatitis B virus.
