Goal. To study the effect of combination antiviral therapy with tenofovir and emtricitabine or lamivudine with and without prior monotherapy with lamivudine. Study. We reviewed charts of 31 HIV-/HBV-coinfected patients. Twelve 3TC-naïve patients initially received tenofovir plus emtricitabine. Nineteen epivir experienced patients who had previously failed epivir were given tenofovir plus emtricitabine. Results. Baseline median HBV DNA was similar in the epivir-naïve (5.8×107 copies/mL) and experienced group (7.3×107 copies/mL, P  =  .65). The median time to complete suppression of HBV was 466 days in the naïve group and 877 days in the experienced (P  =  .001). After 12 months, 6/10 (60%) naïve patients and 3/14 (21%) experienced patients had HBV DNA below the detectionlimit (P  =  .067). After 24 months, 5/5 (100%) naïve patients and 4/13 (31%) experienced patients had an undetectable HBV DNA level (P  =  .015). Conclusions. The median time to suppression of HBV DNA was significantly shorter among treatment naïve patients. There was a significantly greater proportion of naïve patients with suppressed HBV DNA at 24 months. Our results support using initial dual therapy in those with HIV/HBV coinfection.
