Hello, Mlicool, and welcome to the forum. I am sorry that your FIL is so sick. Is he on a transplant list? If so, he is certainly at the top of it, if he has been through evaluation and found to be a good candidate for transplant. If not, you can expect the worst. He is in liver failure and will not live much longer without a transplant. Most transplants occur with a MELD in the mid to high 30s up to low 40s.
I assume your father has never had treatment for hep C or it didn't work for him. At this stage, his only chance of living is a transplant. I have been through evaluation myself and was placed on the waiting list July 18th of this year. My current MELD is a 22, so I feel transplant is not going to happen for me anytime soon.
Where is your FIL hospitalized? Is it a transplant center, as well?
Hugs,
Connie
