Exclusion criteria
Exclusion criteria: 1. Histological or radiological evidence of cirrhosis 2. HIV infection 3. History of alcohol abuse or histological evidence of alcoholic liver disease 4. History of any long-term drug ingestion 5. Histological evidence of metabolic liver disease (haemochromatosis, Wilson?s disease, a1-antitrypsin deficiency) or autoimmune liver disease [antibodies to M2 antigen, Perinuclear antineutrophil cytoplasmic antibodies (p-ANCA), nuclear antigens, microsomes or smooth muscle] 6.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Proportion of patients who successfully step down to lamivudine monotherapy with virological control of replication throughout | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Proportion of patients who, even if there is virological rebound, achieve successful control on re-introduction of tenofovir 2. Accuracy of ALT monitoring in comparison with viral load monitoring 3. Accuracy of HBsAg quantification compared to viral load monitoring The primary and secondary outcomes will be assessed by virological measurements in blood samples obtained every 3 months. | — |
