    Review, Journal:  Telbivudine-induced rhabdomyolysis in a patient undergoing haemodialysis: A case report and review of literature. (Pubmed Central) -  Dec 27, 2023   
    While his CK and myoglobin levels decreased rapidly, his muscle weakness and pain improved slowly. Learning points include: patients undergoing haemodialysis and concomitantly receiving antiviral treatment for HBV, should have their serum levels of CK and myoglobin monitored regularly; treatment with corticosteroids maybe required; relief from rhabdomyolysis-induced muscle weakness and pain may be slow due to nerve fibre damage.

    Journal:  High Frequency of Antiviral Resistance Mutations in HBV Genotypes A2 and H: Multidrug Resistance Strains in Mexico. (Pubmed Central) -  Aug 14, 2023   
    Lamivudine (3TC), telbivudine (LdT), entecavir (ETV), adefovir (ADF), and tenofovir (TFV) are drugs used to treat hepatitis B virus (HBV) infection, but specific mutations allow some viruses to become resistant to antiviral drugs or to acquire immune escape capacities...Resistance mutations were found in genotypes A2 (11.8%, 2/17), and H (10.2%, 11/108), and escape mutations were detected in HBV genotypes A2 (11.8%, 2/17), H (10.2%, 11/108), F1b (9.1%, 1/11) and G (5.6%, 1/18). The highest prevalence of antiviral resistance mutations or escape mutations was detected in HBV genotypes A2 and H. The earliest cases of HBV multidrug resistance were detected in Mexico.

    Break Down of a Root Cause: A Case of Potential Tenofovir Induced Rhabdomyolysis (Exhibit Hall) -  Jul 29, 2023 - Abstract #ACG2023ACG_2937;    
    Our patient presented with RM without common risk factors and an unrevealing workup...In a case of chronic hepatitis B with a patient on telbivudine, RM occurred shortly after the addition of tenofovir, leading to suspicion for a combination effect...To the best of our knowledge, there has not been a case of RM in a non-HIV patient with chronic hepatitis B on tenofovir alone. While our case cannot prove causation, we suggest a high level of suspicion should be given to tenofovir toxicity in future cases of RM if no other obvious etiology is identified.

    Hepatitis delta treatment utilization in the United States: an analysis of commercially insured adults with hepatitis delta virus infection (Poster Area) -  Apr 12, 2023 - Abstract #EASLILC2023EASL_ILC_330;    
    In a large US national, primarily commercial, healthcare claims database, fewer than 40% of patients with HDV were treated with HBV-specific antiviral therapies, and very few patients (1.1%) were treated with Peg-IFN, the current off label standard of care for HDV infection. Greater awareness of the importance of timely initiation of antiviral therapy for patients with combined HBV/HDV infection is urgently needed.

    Retrospective data, Journal:  Meta-Analysis of the Risk for Abnormal Liver Function in Pregnancy with High HBV DNA After Antiviral Therapy Withdrawal. (Pubmed Central) -  Sep 20, 2022   
    The telbivudine treatment group was compared with the control group: at 0-12 weeks: RR = 0.77; 95% CI, 0.43-1.39; at 12-24 weeks: RR = 0.62, 95% CI, 0.23-1.64...There was no significant difference between the 4-week group and the 4-12 week group and the control group. In pregnant women with a high HBV DNA load, immediate withdrawal after antiviral treatment in the second or third trimester of pregnancy did not increase the risk for ALF after delivery.

    Clinical, Journal:  Developmental consequences of children born from mothers with telbivudine treatment during late pregnancy: A prospective study with 3-year follow-up. (Pubmed Central) -  Jan 27, 2022   
    Multivariate regression analyses showed that exposure to LdT during pregnancy was independently associated with infant's development in gross motor (OR 6.49, 95% CI 1.37-30.20, P = 0.02) and adaptive (OR 0.18, 95% CI 0.05-0.71, P = 0.01) at 36 months. These results suggest that prenatal LdT exposure might affect neurological development in long-term observation.Abbreviations: LdT: telbivudine; HBV: hepatitis B virus; HBsAg: hepatitis B surface antigen; HBeAg: hepatitis Be antigen; HbsAb: hepatitis B surface antibody; ALT: alanine aminotransferase; NA: nucleoside/nucleotide analog; LAM: lamivudine; MTCT: mother-to-child transmission; GDS: Gesell Developmental Schedule; OR: odds ratio; CI: confidence interval; DQ: developmental quotient; RMB: renminbi; BMI: body mass Index; HBIG: hepatitis B immunoglobulin.

    Clinical, Journal:  Comparison of the efficacy and safety of tenofovir and telbivudine in interrupting mother-to-child transmission of hepatitis B virus. (Pubmed Central) -  Jan 27, 2022   
    However, no serious adverse events were observed in infants and mothers of all groups.TBV and TDF can effectively reduce the HBV DNA level and MTCT rate in pregnant women with high HBV DNA load (≥2 × 105 IU/mL); both antiviral drugs are safe for infants and mothers. Since TDF was more effective in reducing HBV DNA levels during the second trimester, its use during the period is recommended to prevent HBV MTCT.

    We found a moderate or strong signal for increased risk of spontaneous abortion when comparing ETV with tenofovir disoproxil fumarate (TDF) and telbivudine (LdT), with RORs equal to 1.58 (95% CI, 1.09-2.30) and 2.13 (95% CI, 1.04-4.36), respectively...Futhermore, a strong signal for increased risk of spontaneous abortion was identified in patients with HBV infection when comparing ETV or ADV with lamivudine (LAM), with RORs of 3.55 (95% CI, 1.54-8.18) and 2.85 (95% CI, 1.15-7.08), respectively...Moreover, no obvious signal association of human teratogenicity with exposure to ETV or ADV was identified in fetuses during pregnancy. Nevertheless, owing to the limitations of a spontaneous reporting database, which inevitably contains potential biases, there is a pressing need for well-designed comparative safety studies to validate these results in clinical practice.
