Significant histological changes and satisfying antiviral efficacy in chronic hepatitis B virus infection patients with normal alanine aminotransferase. Antiviral therapy decision in chronic HBV patients with normal ALT. Clin Res Hepatol Gastroenterol 2021; 45:101463. [PMID: 32571749 DOI: 10.1016/j.clinre.2020.05.011] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Accepted: 05/06/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIMS A proportion of chronic hepatitis B virus (HBV) infection patients with normal alanine aminotransferase (ALT) should start antiviral therapy based on liver biopsy. We aim to evaluate the proportion of such patients, find noninvasive methods for identifying and then evaluate antiviral efficacy. METHODS 253 chronic HBV infection patients with normal ALT were analyzed at baseline and 57 patients with histological indication for antiviral therapy (Histology activity index ≥5 and/or Ishak fibrosis score ≥3) and 140 patients with elevated ALT received entecavir therapy and were followed-up to 78 weeks with a second liver biopsy in this multi-center study. RESULTS 127 (50.2%) of 253 patients with normal ALT fulfilled histological indication for antiviral therapy. Aspartate aminotransferase (P=0.049), anti-hepatitis B virus core antibody (P=0.001) and liver stiffness measurement (P=0.000) were independent variables for identifying histological indication for antiviral therapy. A noninvasive model (AAF) performed best among independent variables and other noninvasive models with area under the operating characteristic curve of 0.887. Antiviral efficacy showed that 38 (66.7%) of 57 patients had undetectable HBV DNA. 12 (41.4%) of 29 patients who were hepatitis B e antigen (HBeAg)-positive at baseline achieved HBeAg loss and 3 (10.3%) achieved HBeAg seroconversion. 25 (43.9%) of 57 patients achieved histological response. Moreover, 57 patients with normal ALT had a similar antiviral therapy efficacy with 140 patients with elevated ALT (P>0.1) except proportion of inflammation improvement and histological response (P=0.005, P=0.049). CONCLUSIONS Half of chronic HBV patients with normal ALT should start antiviral therapy based on liver biopsy. A noninvasive model could be used as a reliable tool for antiviral therapy decision. Patients with normal or elevated ALT had a similar antiviral efficacy.

Efficacy of tenofovir disoproxil fumarate switch therapy in chronic hepatitis B patients with suboptimal response to adefovir-based combination therapy. Exp Ther Med 2019; 17:1196-1205. [PMID: 30679993 PMCID: PMC6327499 DOI: 10.3892/etm.2018.7081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2018] [Accepted: 09/06/2018] [Indexed: 02/05/2023] Open
Abstract
In the present study, the efficacy and safety of tenofovir disoproxil fumarate (TDF) switch therapy were assessed in patients with chronic hepatitis B exhibiting a suboptimal response to adefovir (ADV)-based combination therapy. First, the efficacy of the TDF switch therapy was retrospectively evaluated in 50 patients with chronic hepatitis B who failed to respond to ADV-based combination treatment. Among those, 48 patients with a median age of 35 years were hepatitis B e antigen (HBeAg)-positive and 17, 14 and 19 patients were previously treated with lamivudine (LAM) plus ADV, telbivudine plus ADV and entecavir (ETV) plus ADV, respectively. A total of 41 patients were treated with TDF alone and 9 with TDF plus ETV. The median time of follow-up was 102 weeks. The primary end-point was the cumulative probability of achieving a complete virologic response (CVR). The secondary end-points were the rate of alanine aminotransferase (ALT) normalization, HBeAg seroconversion in HBeAg-positive patients, and the plasma levels of creatinine and creatine kinase. The mean serum hepatitis B virus DNA levels prior to initiation of the TDF switch therapy were 4.8±1.6 log10IU/ml. The cumulative probability of achieving a VR at 24, 48, 96 and 108 weeks was 52.0, 76.0, 89.8 and 94.9%, respectively. The cumulative probability of normalization of ALT at 12, 24, 36, 48, 60,72, 84, 96, 108, 120 and 132 weeks was 34, 44, 50, 58, 66, 70, 74, 80, 90, 92 and 94%, respectively. HBeAg seroconversion was achieved in 5 patients. During the follow-up, 6 patients suffered from a virologic breakthrough, 3 patients failed to respond to the TDF treatment and the remaining patients were able to obtain VR following the continuation of TDF treatment. Slightly elevated serum levels of creatinine were observed in one patient, whereas creatine kinase activity did not increase in any of the subjects. In conclusion, TDF switch therapy is efficient and safe for patients with chronic hepatitis B with a suboptimal response to ADV-based combination therapy.
