Can HE return after a liver transplant in a 58-year-old man?

Question

Hello doctor,

My father is 58 years old and has liver cirrhosis caused by alcohol-related liver disease. He used to have repeated episodes of hepatic encephalopathy, with symptoms like confusion and drowsiness.

He underwent a liver transplant three months ago and is currently stable. Before the transplant, he was taking Lactulose and Rifaximin. Now, his doctor has continued Rifaximin for some time. His recent reports show slightly raised ammonia levels, but they are improving, and his liver function tests are stable.

Will Rifaximin completely prevent hepatic encephalopathy after a liver transplant, or is there still a chance it can return?
Also, how long is this medication usually continued after transplant?

Please suggest.

Thank you.

Hello,

Welcome to icliniq.com.

Thank you for reaching out.

I completely understand your concern about your father’s recovery after his liver transplant. You are doing the right thing by closely monitoring his health and reports.

Rifaximin does not completely guarantee that hepatic encephalopathy (HE, a brain condition caused by liver problems, leading to confusion, drowsiness, and changes in thinking) will never return, but it significantly reduces the risk. After a liver transplant, the new liver usually corrects the main cause of HE.

However, during the early recovery phase, the body is still adjusting. Since his ammonia levels are only slightly elevated and improving, Rifaximin is helping control ammonia production and supporting this transition.

There is still a small chance of recurrence, but the risk is much lower than before the transplant. In the first few months, especially within three to six months after surgery, the body is still healing and adapting.

If the liver continues to function well without complications like rejection or infection, the likelihood of HE returning becomes very low over time.

The duration of Rifaximin use after transplant varies from person to person. In most cases, it is continued for about three to six months. Once liver function stabilizes and ammonia levels return to normal, doctors may gradually reduce or stop the medication.

If your father had frequent or severe episodes of HE before the transplant, the doctor may choose to continue it longer for added safety.

Overall, your father’s current progress sounds reassuring, and regular follow-ups with his transplant team will help ensure the best recovery.

I hope this helps.
