Sue, I did not find any information about Psoriatic Cirrhosis. I did see some references that mention that autoimmune diseases like psoriatic arthritis can affect other organs, including liver. Also, there are many diseases that are non alcoholic. This could be a rare condition, or a combination of conditions. Either way, I want you to share this link to Mayo Liver Transplant Department with them. They can read about the Mayo Liver transplant Dept, and use the Contact information to speak to someone in the liver transplant dept about a second opinion.

I am a patient, and from my own experience, every liver patient has a journey that is as unique as that individual. I do not know, nor am I qualified to answer your questions about specific treatment, consequences, outcomes. Those questions should be addressed only by your friends liver specialist. I am willing, and available to provide any support, resources, and information from my own experiences that could be helpful. I received my own combined liver and kidney transplant at Mayo in 2009.

Let me know how I, or any of our members can be of support. We are always eager to talk with fellow patients on our health journeys.
