Brief Summary:
Tenofovir alafenamide (TAF), active against both HIV and HBV, demonstrates similar antiviral efficacy but improved renal and bone safety compared to tenofovir disoproxil fumarate (TDF) in HIV-1-infected patients. HIV-1-infected patients whose estimated glomerular filtration rate (eGFR) between 30-69 mL/min were shown to have minimal change in eGFR and improved proteinuria, albuminuria, and bone mineral density after switching to a single-tablet regimen containing Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide (EVG/cob/FTC/TAF). For treatment of chronic HBV infection, a similar proportion of HBV-monoinfected patients who received TAF and those who received TDF achieved undetectable HBV DNA at 48 weeks of therapy. Although TAF is effective for HIV and HBV suppression, data on efficacy of TAF are limited among patients co-infected with both viruses. Currently, only one open-label, single-arm study had investigated the efficacy and safety of TAF in HIV/HBV-coinfected patients. In this study, 72 HIV/HBV-coinfected patients switching to EVG/cob/FTC/TAF were enrolled, and 91.7% of them maintained or achieved virologic suppression for both HIV and HBV at 48 weeks of therapy. Seroconversion occurred in 2.9% of HBsAg-positive participants and in 3.3% of HBeAg-positive participants. Improvements in eGFR and declines in markers of bone turnover of the participants were observed. The limitations of the above study are the small sample size. Taiwan is a country hyperendemic for HBV infection, with 19.8% of HIV-positive patients who were born before the implementation of nationwide neonatal vaccination in 1986 had concurrent chronic HBV infection. To further the understanding of the difference between TAF- and TDF-containing combination antiretroviral therapy among HIV/HBV-coinfected patients, the investigators plan to conduct an observational study to evaluate the efficacy and safety of EVG/cob/FTC/TAF as maintenance treatment of HIV/HBV-coinfected patients.
