Evaluation of the Effectiveness of Tenofovir in Chronic Hepatitis B Patients

Objectives: HBV infection is a global public health problem. Tenofovir disoproxil fumarate and tenofovir alafenamide are nucleotide reverse transcriptase inhibitors and used for the treatment of chronic Hepatitis B infection. The aim of this study was to evaluate treatment response and efficacy of Tenofovir disoproxil fumarate. Materials and Methods: The study included hepatitis B positive patients who started to use Tenofovir disoproxil fumarate. We retrospectively reviewed electronic medical files of Hepatitis B patients. Hepatitis B surface antigen, Hepatitis B surface antibody, Hepatitis B e antigens, Hepatitis B e antibody, Hepatitis B viral DNA, aspartate aminotransferase, alanine aminotransferase values were evaluated in the 1st, 3rd, 6th, 9th, and 12th months. Result: None of the patients under Tenofovir disoproxil fumarate treatment was “primary resistant”. Alanine aminotransferase normalization at 12th month was seen in 80.4% of study population. Hepatitis B surface antigen seroconversion was detected only in one patient (0.85%) at 9th months and Hepatitis B e antigen seroconversion was observed in 9 patients (8.3%) under Tenofovir disoproxil fumarate treatment. At the sixth month of Tenofovir disoproxil fumarate treatment, complete response was found in 77 (65.8%), partial response in 21 (18%) and inadequate response were in 19 (16.2%). Among Hepatitis B e antigen positive patients, 44 (80 %) patients had undetectable Hepatitis B virus DNA levels at the end of 12th month and among Hepatitis B e antigens negative patients, 52 (91.2%) patients had undetectable Hepatitis B DNA levels at the end of 12th month (p
