Antiviral therapy is aimed to persistently suppress hepatitis B virus (HBV) to prevent liver complications and improve survival and long-term administration of nucleos(t)ide analogues represents an attractive treatment strategy. Five oral analogues are available, and all inhibit viral replication in most patients during the first year of therapy. By converse, long-term monotherapy is associated to high rates of resistance with lamivudine, and intermediate rates with Adefovir and Telbivudine. Third-generation analogues such as Entecavir and Tenofovir may efficiently inhibits viral replication in most patient for many years as they couple potency and high genetic barrier. In patients developing drug-resistance, specific rescue protocols based upon 'early add-on' have been developed to rapidly and efficiently control viral replication. In cirrhotics, long-term effective analog-based therapy prevented clinical decompensation for many years, but not liver cancer development. Long-term administration of NUCs, either as a monotherapy or as a sequential combination, inhibits HBV replication in most HBeAg-negative patients for at least 5 years, preventing clinical decompensation in cirrhotics.

This study aims to assess the nephrotoxicity and efficacy of tenofovir disoproxil fumarate (tenofovir), telbivudine and entecavir. A retrospective study of 587 patients with chronic hepatitis B treated with tenofovir (n = 170), telbivudine (n = 184) and entecavir (n = 233) for at least 1 year. Renal function and efficacy were assessed. The estimated glomerular filtration rate (eGFR) decreased significantly in the tenofovir group after a mean of 17 months treatment (from 92.2 to 85.6 mL/min/1.73 m(2), p < 0.001), but increased in the telbivudine group after a mean of 32 months of treatment (from 86.1 to 95 mL/min/1.73 m(2), p < 0.001). There was no significant change in eGFR in the entecavir group after a mean of 44 months. By multivariate analysis, pre-existing renal insufficiency (p = 0.003), tenofovir (p = 0.007) and diuretic treatment (p = 0.001) were independent predictors for renal function deterioration. Cumulative virological breakthrough was 0% in tenofovir after 2 years, 3.4% in entecavir after 7 years and 22.9% in telbivudine after 5 years. Liver cirrhosis (p = 0.008) and virological breakthrough (p = 0.040) were independently associated with increased risk of hepatocellular carcinoma development. Tenofovir may lead to deterioration in renal function as assessed by serial eGFR measurements. Although telbivudine appeared to be associated with an improvement in eGFR, it was associated with high rates of virological breakthrough, which was an independent risk factor for HCC development. With low rates of virological breakthrough and preservation of renal function, entecavir could be the best choice among these three agents.
