Background and AimsTenofovir disoproxil fumarate (TDF) demonstrated potent and sustainable antiviral efficacy and a good safety profile in patients with chronic hepatitis B (CHB) in controlled clinical trials. Real-world data are important to confirm effectiveness and safety data in patient populations encountered in routine clinical practice.MethodsThis non-interventional, prospective, 36-month study included treatment-naïve and treatment-experienced patients with CHB initiating their first TDF regimen (monotherapy or combination therapy) in routine clinical practice in France. Clinical, virologic, biochemical, compliance, and safety data were collected.ResultsData from 440 consecutive patients from 58 centers were analyzed. The majority of the cohort was male (71 %), hepatitis B “e” antigen-negative (HBeAg–) (74 %), and treatment-experienced (56 %); 11 % were aged ≥65 years; and comorbidities were reported in 39 %. After 12 months, 92 % of the overall cohort achieved virologic response (HBV DNA <69 IU/mL) which was maintained to 36 months (96 %); virologic response was achieved by >90 % of patients irrespective of HBeAg status, age, or prior treatment history. At 36 months, 77 % of patients had normal alanine aminotransferase levels. Fourteen patients lost hepatis B surface (HBs) antigen, and seven seroconverted to anti-HBs. TDF was well tolerated over the 36-month study, including in 14 women who became pregnant during the study. Median estimated glomerular filtration rate did not change markedly from baseline irrespective of prior treatment history.ConclusionsTDF demonstrated potent virologic and biochemical responses across a broad range of patients reflective of routine clinical practice. The safety profile was consistent with results from pivotal trials.

TE in alcoholics is influenced by major variations in the biochemical activity of the disease. The kinetics of variation of TE suggest that this method may be useful to assess alcohol abuse and control.

: More than half of our population of HIV-infected children had biological and/or radiological signs of liver affection. Regular follow-up of liver function is necessary in these patients, which is now possible with noninvasive procedures.
