Hello, Theresa, and welcome to the forum. I am so very sorry to hear about what is happening to your b.f. Unfortunately, the posts you picked up on are two years old. You might get more replies if you start a New Topic. You can copy and paste what you've already written to a new page.
I have no idea why your b.f.'s liver and kidneys suddenly failed, unless it was drug related or he ingested a toxin. I am sure the doctors are doing everything they can for him. Please do keep us updated.
JAdams, welcome. You might want to post on a separate thread (click on New Topic instead of Reply) so more people will see it and you will get more input. Your friend's problems may be related to toxicity from some drug she has taken, such as acetaminophen.
