Frailty after Liver Transplantation: A Complex Unexplored Issue.

Frailty is a multidimensional syndrome predominantly studied in the elderly, characterized by reduced resistance to stressors due to diminished physiological reserve and resilience. Advances in surgical techniques and immunosuppressive drugs have improved long-term survival rates in solid organ transplant recipients, yet the 10-year survival is satisfying. However, liver transplant recipients have a noteworthy risk of developing frailty status. After liver transplant, frailty can be favored by socioeconomic, cultural, and health-related factors, leading to increased risks of hospitalization, morbidity, and mortality. Various tools for frailty assessment exist, but none are universally validated for post-transplant patients. The integration of socioeconomic and psychological factors into frailty evaluation could improve quality of life and long-term outcomes for transplant recipients. Multidisciplinary approaches, including psychosocial support, are essential for managing frailty and enhancing the overall care of transplanted patients. This narrative review aims to comprehensively address the principal frailty risk factors associated with liver transplantation.
