Abstract
Introduction:HBV is major health problem globally due to complications, including ACLF, cirrhosis and hepa¬tocellular carcinoma. ACLF due to exacerbation of CHB is associate with 30%-70% mortality. Reduction of HBV-DNA is therefore a target of therapy in ACLF-B.Methods:Patients with spontaneous reactivation of HBV [(ALT >5×ULN or >2× baseline) and HBV-DNA >20,000 IU/ml] were randomized to Tenofovir mono therapy (300 mg/day) or Tenofovir plus Telbivudine (600 mg/day) dual therapy with standard care. Clinical and biochemical parameters were evaluated at baseline, 1 week, 4 weeks and at 3 months. Virological evaluation was done at baseline and at 3 months. Primary end points were reduction of HBV-DNA and resolution of ascites, as applied. Secondary end point was reduction of liver related complications, therapy related adverse effects and survival at 3 months.Results:27 patients were enrolled. 15 received mono therapy with Tenofovir and 12 received dual therapy (Tenofovir plus Telbivudine). Baseline parameters in 2 groups had no significant difference. In both groups there was significant improvement of S. bilirubin, ALT, INR, CTP score and MELD score. Only MELD score showed significant improvement in patient with dual therapy at 3 months in comparison to mono therapy. 11 patients on Tenofovir mono therapy (n=15) showed undetected HBV-DNA (91.7%) at 3 months and one patient had detectable HBV-DNA (<2,000 IU/ml). 10 patients on dual therapy (n=12) had undetectable HBV-DNA (100%). Ascites resolved in 3 patients in both groups. Patients receiving dual therapy showed significant improvement in AKI on follow up compared to those on Tenofovir mono therapy. Among 5 deaths, 3 received mono therapy with Tenofovir and 2 dual therapy. Predictors of mortality had high S. bilirubin, HBV-DNA, MELD score and CTP score.Conclusion:In spontaneous reactivation of HBV presenting as ACLF, combination of Telbivudine plus Tenofovir is safer with less nephrotoxicity and better outcomes.
