Abstract
Control of HBV infection in HIV/HBV co-infected patients treated with antiretroviral therapy – experience of Lodz Centre
- Clinic of Infectious Diseases and Hepatology, Medical University of Lodz, Poland
Aim of the study
To analyse the impact of combined antiretroviral therapy (cART) on selected markers of hepatitis B virus (HBV) infection, as well as assessment of the degree of fibrosis in antiretroviral patients who had HIV/HBV co-infection.
Material and methods
Analysis of HBs antigen (HBsAg), anti-HBs, HBsAg levels, anti-HDV, anti-HCV, as well as assessment of HBV DNA viraemia and liver fibrosis by elastography in people with HIV/HBV co-infection.
Results
Among 515 people under the care of the Lodz Centre at the time of treatment initiation 28 people (5.4%) HBsAg was detected. In HIV/HBV coinfected patients 14 people (50%) had anti-HCV and 6 (21.6%) had anti-HDV. In the group of 23 people treated with antiretroviral therapy for more than 12 months, all but one patient achieved HBV viraemia below the detection threshold. Six (26.1%) eliminated HBsAg, 3 (13%) produced anti-HBs. In the group we examined, four patients has fibrosis at level F4 on the Metavir scale – 3 patients were treated for more than 12 months and one patient was treated for less than 12 months.
Conclusions
Antiretroviral treatment of patients co-infected with HIV/HBV based on tenofovir (in the form of disoproxil or alafenamide) with emtricitabine or lamivudine leads to virological control of HBV infection.
