• Nucleos(t)ide analogues [NA(s)] has evolved the therapeutic 

manipulation of patients with chronic hepatitis B (CHB) improving the 

outcome of HBV transplant patients after liver transplantation (LT). 

• NAs have been used, either as monoprophylaxis or in combination 

with hepatitis B immune globulin (HBIG) after LT. 

BACKGROUND

Page 3: TELBIVUDINE IS ASSOCIATED WITH IMPROVEMENT OF RENAL FUNCTION IN PATIENTS AFTER LIVER TRANSPLANTATION 1 Maria Ioannidou, 1 Evangelos Cholongitas, 2 Themistoklis

• During long-term therapy with NAs in CHB patients, minimal rates of 

GFR decline have been reported, except for telbivudine

• LT recipients may represent a group of patients, in which the role of 

telbivudine needs further evaluation, because these patients are 

considered at high risk for renal dysfunction due to the concomitant 

use of the calcineurin inhibitors (CNIs)

BACKGROUND

OBJECTIVES

To evaluate the impact of telbivudine on renal function in liver transplant (LT) recipients

Page 5: TELBIVUDINE IS ASSOCIATED WITH IMPROVEMENT OF RENAL FUNCTION IN PATIENTS AFTER LIVER TRANSPLANTATION 1 Maria Ioannidou, 1 Evangelos Cholongitas, 2 Themistoklis

• 34 recipients were included in this prospective study 

• Inclusion criteria: 

    a) they had no evidence of HBV recurrence, and 

    b) they were under stable immunosuppression regimen without

         steroids during the last 12 months before baseline

MATERIALS & METHODS

Page 6: TELBIVUDINE IS ASSOCIATED WITH IMPROVEMENT OF RENAL FUNCTION IN PATIENTS AFTER LIVER TRANSPLANTATION 1 Maria Ioannidou, 1 Evangelos Cholongitas, 2 Themistoklis

• In 17 recipients (study group 1) remained on the same NA(s) as before baseline 

and were followed for 12 months (1st period). At this time point (month 12), they 

were switched to telbivudine monoprophylaxis for another 12 months (2nd period).

• The rest 17 (group 2)  patients continued their original non-telbivudine NA(s) 

prophylaxis.

• The changes GFR (ΔGFR) between baseline and after 12 months (1st period) and 

between 12 months and 24 months (2nd period) were evaluated.

CONCLUSIONS

• We showed that telbivudine administration in LT recipients for HBV cirrhosis was effective and it was associated with significant improvement in renal function, 

• However, this remains to be confirmed in larger well-designed studies
