Telbivudine prevents hepatitis B virus recurrence and improves renal function after liver transplantation in clinical observation of 17 cases / 中华器官移植杂志

ABSTRACT

Objective To approach the effect of telbivudine for preventing recurrence of virus and improving renal function in patients with hepatitis B cirrhosis after liver transplantation with renal insufficiency,and observe the mid-and long-term efficacy.Methods We prospectively researched 17 cases of hepatitis B cirrhosis after liver transplantation with renal insufficiency.Maintenance irnmunosuppression protocol at our centre mainly included calcineurin inhibitor (tacrolimus for 12 cases,and sirolimus for 5 cases).These recipients (n =17) remained under the entecavir (n =10),tenofovir (n =4),lamivudine + adefovir (n =3) for at least 6 months before transformation to telbivudine.We detected HBV-DNA level in serum and ensured no rejection during study,necessarily punctured the graft liver for biopsy to determine if there was rejection.The basal values of blood serum creatinine (Scr) and estimated glomerular filtration rate (eGFR,CKD-EPI formula) were recorded.The Scr and eGFR at 6th month before research and basal values and at 6th and 12th month after telbivudine administration were detected,at the same time the general state and adverse reactions were evaluated.Results During the average follow-up period of 20.2 months,1 patients died.The Ser levels detected in the rest 16 patients were 105.74± 18.24,112.26± 18.67,96.48±22.0 and 89.17± 19.56μμmol/L respectively at 6th month before,basal time and 6th,12th month after telbivudine administration.The eGFR values were 72.56 ± 14.39,66.23 ± 16.61,79.77 ± 20.15 and 83.93 ± 23.67 mL/(minute,m2) at different time points respectively.As compared with the basal value,the Scr and eGFR levels were improved obviously (P＜0.05) at 6th and 12th month after telbivudine administration.The proportion of patients with eGFR ＜60 mL/(min·m2) in 16 cases was 25％,37.5％,12.5％ and 6.3％ respectively at 6th month before,basal time and 6th,12th month after telbivudine administration.The serum creatine phosphokinase level was increased (1 023 IU/L) in 1 patient (6.3％),and decreased after transformation of telbivudine to tenofovir at 3rd month after end of research.No rejection and HBV occurred.Conclusion The telbivudine improves renal function in patients with hepatitis B cirrhosis after liver transplantation with renal insufficiency.Meanwhile,telbivudine prevents hepatitis virus B recurrence.However,large samples of long-term clinical data are needed to further confirm.
