How many years will he be in prison? Hepatitis is a slow progressing disease and if he hasn't had it very long he could treat when he gets out. Do you know the stage of his liver damage? With little or no damage yet he should be ok for some time,if not years. I do believe he should treat again with a good Dr as soon as he's able. I hope someone out there knows a prisoner advocacy group he or you could contact.
The mouth sores are most likely related to the interferon when you are on treatment but after about a week or two when the interferon leaves your body so should they.
It seems the prison system didn't want to pay for his treatment, something I heartedly disagree with considering how much rampant hcv is in the jail system. My husband was in and out all of his life (dead now) and they always just told him he was fine and didn't need to treat because his liver enzymes were good (Uh yes he wasn't drinking or doing drugs in jail so his liver did have some downtime).
Anyway - as you realize the cost of treatment is exorbitantly staggering I'm sure you know why they did this to him. Yes, I cannot imagine how they could consider stopping treatment without a 12 week PCR to see if he had cleared. While a 60% reduction at week 4 is pretty slow he was responding and increasing the dosage of riba might have done something positive about getting him to UND.
My best bet the doctor just didn't care.
Hopefully since you son is young and living a liver healthy lifestyle right now (whether by choice or not!) he will have a chance to treat again.
I wish you all the best. As someone who's been there (although it wasn't my son which is heartbreaking) I do know the frustration and heartache you are going through and I hope somehow you can get this situation resolved and perhaps he can attempt to treat again.
I'll leave it to the smart guys in here to give you any stats or things. I'm kind of just all about the heart (cause I'm not as smart ;)
Good luck!

The mouth sores are a sign that the main drug, interferon, is reducing his white blood cell level. There are medications to counteract that but they are very very expensive and that may have had a role in their decision.
