Liver Transplant Criteria and Process for Hepatitis C
A liver transplant can be a life-saving option for individuals suffering from severe liver damage, particularly those with Hepatitis C (HCV)-related liver damage.
In such cases, the surgery involves replacing the damaged liver with a healthy donor liver, a process that can take up to 8 hours. After the surgery, the transplant recipient is typically taken to a recovery room for a few hours before being transferred to the intensive care unit (ICU).
For those who undergo liver transplantation due to HCV-related liver damage, long-term survival rates are generally favorable. Five-year survival rates for liver transplant recipients in related liver failure contexts, including acute-on-chronic liver failure (ACLF) and presumably HCV-related damage, are around 76% or higher, with one-year survival often exceeding 80%.
Life expectancy post-transplant substantially depends on multiple factors such as the severity of liver disease before transplant, comorbidities, patient age, and the occurrence of complications. In well-selected patients, liver transplantation offers a significant survival benefit, adding many years of life expectancy compared to patients who do not receive a transplant. For example, living donor liver transplants have reported high 1-year patient survival rates (around 97%) and extended life expectancy gains of up to 13–17 years for some patients.
The introduction of direct-acting antiviral (DAA) therapies for Hepatitis C has transformed outcomes for transplant recipients. Achieving a sustained virologic response (SVR), meaning the virus is no longer detectable after treatment, significantly improves liver histology, reduces the risk of disease progression, and lowers liver-related mortality. This means that patients who undergo liver transplant and clear HCV with antiviral therapies post-transplant have much better long-term outcomes, as reinfection of the graft can be effectively controlled or prevented.
However, the criteria for a liver transplant require a person to have irreversible liver disease that would be fatal without a transplant, have no contraindications for the transplant surgery, and pass an extensive transplant evaluation process. Contraindications for a liver transplant include cancer that has spread outside the liver, severe heart and/or lung disorders, uncontrolled sepsis, acquired immune deficiency syndrome (AIDS), cancer in the bile ducts, persistent refusal of medical care, an abnormality in internal anatomy that makes transplant impossible, and lack of help or social support.
HCV infections are a leading cause of liver transplants in the United States. Approximately 5-25% of individuals with a chronic HCV infection will develop cirrhosis within 10-20 years. People with untreated chronic HCV infections may eventually develop complications of the liver, such as cirrhosis or cancer. To try and prevent any potential complications prior to a liver transplant, a person will work with their healthcare team to treat any underlying conditions and ensure they are receiving adequate treatment for the HCV infection.
It's important to note that without a liver transplant, HCV-related liver failure can be life threatening. The National Health Service in the United Kingdom states it can take up to a year to recover from a liver transplant. People who receive a new liver need outpatient follow-up after the transplant, including routine blood work and checkups, to monitor for potential transplant complications and review immunosuppressant medication compliance and side effects.
In conclusion, liver transplants offer a significant survival benefit for individuals with HCV-related liver damage. With careful patient selection, timely transplantation, and effective management of HCV with antiviral treatments, five-year survival rates after liver transplant can be approximately 70-76% or higher, one-year survival rates can approach 97%, and life expectancy can be improved by adding more than a decade in well-selected patients.
