Compare the effect of combined therapy between telbivudine plus adefovir dipivoxil and lamivudine plus adefovir dipivoxil corresponding to renal function in patients with hepatitis B virus infection / 中华肝脏病杂志

ABSTRACT

Objective@#To compare the effect of combined therapy using lamivudine (LAM) plus adefovir (ADV) versus telbivudine (LdT) plus adefovir corresponding to the renal function of CHB patients.@*Methods@#A total of 120 patients with chronic hepatitis B were enrolled. According to single daily dosing, they were divided into 4 groups LdT + ADV group (n = 32), ADV+LdT group (n = 28), LAM + ADV group (n = 38) and ADV + LAM group (n = 22). Hepatorenal function, HBV serological markers, HBV DNA quantification, creatine kinase (CK) and other parameters were examined every 3 months. Serum alanine aminotransferase (ALT) normalization rate, undetectable HBV DNA rate, hepatitis B e antigen (HBeAg) seroconversion rate, level of serum creatinine (CR) and estimated glomerular filtration rate (eGFR) were analyzed at baseline time, and at weeks 24 and 52.Stastical data were analyzed by t- test and analysis of variance, count data using χ 2 test.@*Results@#There was no statistically significant difference between the four groups in terms of ALT normalization rate, HBeAg seroconversion rate, undetectable HBV DNA rate at 24 and 52 weeks. Compared with baseline, at 24 weeks of treatment, there was no significant change in serum creatinine and eGFR in the 4 groups, but after 52 weeks of treatment, serum creatinine decreased in LdT + ADV and ADV + LdT groups and eGFR increased (P < 0.05); Serum creatinine in ADV and ADV + LAM increased, and eGFR was decreased than before (P < 0.05). After treatment, there was no significant difference in renal function between the four groups at 24 weeks, but at week 52, eGFR increased and serum creatinine decreased in LdT + ADV group compared with LAM + ADV group (P < 0.05); ADV + LdT Compared with ADV + LAM group, eGFR increased and serum creatinine decreased (P < 0.05). At 52 weeks of treatment, 5 patients with mildly impaired renal function in the ADV + LdT group [n = 10, eGFR 60-90 ml·min-1 ·(1.73 m2)-1] returned to normal, and none of the ADV + LAM group (n = 9) returned to normal.@*Conclusion@#For patients with mild impaired renal function, adding LdT combined with ADV can improve renal function compared to that of LAM plus ADV.
