Renoprotective Effects of Telbivudine in Chronic Hepatitis B
Hong Kong31 participantsStarted 2013-08-01
Plain-language summary
Renal impairment is common in patients with chronic hepatitis B infection. For those taking nucleotide analogues, renal toxicity of adefovir disoproxil (ADV) and tenofovir disoproxil fumarate (TDF) is a significant concern in chronic hepatitis B (CHB) patients. Early observational clinical data suggested that telbivudine (LdT) might have renoprotective effects. In this prospective study, consecutive CHB patients on combined lamivudine (LAM)+ADV/TDF are switched to LdT+ADV/TDF at recruitment and are followed up for 24 months. Estimated glomerular filtration rate (eGFR) is calculated with the Modification of Diet in Renal Disease (MDRD) equation. The effects of LdT on cell viability and expression of kidney injury or apoptotic biomarkers are investigated in cultured renal tubular epithelial cell line HK-2.
