Rose,
As others have said...knowledge is key. AIH is a fully treatable condition. The earlier it is found the better and as I said before, it sounds like he doesn't have cirrhosis. Sure it's scary initially but the more you know, the more you'll come to see that it doesn't mean that there is a defined time for him to be with you. All patients are different but the majority of AIH patients lead perfectly normal lives with the proper treatment. It sounds like they have given him exactly what he needs to be on. Also make sure he speaks to the doc about calcium + Vit D supplements and a multivitamin. He should have a baseline bone density scan as long term prednisone use can lead to thin bones. He, absolutely, should not have any alcohol. No over the counter medications unless he checks with his hepatologist (he is seeing a hepatologist, ya?). When he starts feeling a little better, exercise will help him tremendously. It also helps with fending off any joint/muscle issues. Try to make sure there are plenty of healthy snacks around. The pred side effects will kick in soon. One is ravenous hunger! At least it was for me but as I said, everyone's different. There is a lot of water retention and weight gain with the pred but if the munchies are filled with sugary and fatty snacks...more than normal weight will be gained. Weight gain for liver patients is an issue as you need to try to avoid fatty liver disease on top of all that. Other side effects, irritability (not just sad emotional changes but anger as well), facial hair (not so much an issue with men but I sure wasn't happy when my chin needed waxing ), I developed a slight hump on my upper back, insomnia was a big one for me. My hep prescribed different sleeping pills till I found one that worked. I only took it every 3 days and dealt with some of the insomnia. Had I known it was coming I would have planned on painting the house in the middle of the night...instead I lay there ticked off that I couldn't sleep I did clean the freezer and garage out at 2 am on separate nights! So it's kinda productive. Have him rest/sleep whenever he needs to. All the side effects were pretty much gone by the time I was decreased to 10mg. Think positive thoughts as there is always a silver lining, we just need to look for it sometimes.
I am currently off the pred and only on azathioprine. I was on pred for a total of 22 months. The doctor's goal will be to get him off the pred as the long term side effects aren't good for the body. If he needs to stay on the pred because his body won't let him off, then they'll try to maintain him on the lowest possible dose...again, side effects are gone on the lower than 10mg dose for most patients. But that's to think about later.
Sorry for the long winded-ness. Ask whatever you need to ask. Oh and you said he's lacking energy? The pred might change that soon enough. It may make him feel like superman, unstoppable...that's where the insomnia bit comes from. I had a huge amount of energy but then again, I know others who couldn't sleep at night but were super sleepy in the day. For me it was like having 20 cups of coffee (that's how my hepatologist put it---I went in for a monthly check up when I was still on 30 mg and couldn't stop talking and told him he better lower my dose because I was way too wired). So he did since my lab work was fine!
Do you know how often he's going in for blood work? He should have his labs done before any prednisone weaning. Each drop in pred should be preceded by lab work.
OK...I probably should have avoided the late night java! Gotta hit the hay before my 12 mile training walk in the morning...see...some people live perfectly normal lives with a chronic illness...I gripe about it occasionally when I don't feel like taking my meds or I wouldn't mind having a glass of wine with dinner...but it takes a minute to pull them out and I never ever have a hangover!
Life could be so much worse so I am grateful that if I had to choose a disease, I may have chosen this one
Take care of yourself and see your doc if you feel overwhelmed...then think about how he may feel and that might help you put things into perspective...
