What are your current ALT/AST Values? 11.6 Kpa may not be because of ongoing damage but from before you started taking entecavir. Stay on the medication and make sure ALT/AST are before or near normal range. Also, a bit more context may help. Were you in immune reactive state before? what was your condition before you started taking entecavir?
My present Alt/Ast 26.39/32.47. I started etv 3 years ago when HBV dna is around 176000 and Hbsag 1760. I only did fibroscan last december.
Your CAP of 305 indicates you have fatty liver. So you need to reduce weight by exercise and dieting. If you have high triglycerides you may need to take medication. See your doctor as fatty liver can also cause fibrosis to progress.
