Abstract
Introduction
Frailty and sarcopenia are associated with an increased risk of hospitalization and mortality in patients with end-stage liver disease. The ability to identify frail patients at risk of adverse outcomes could help optimize liver transplant (LT) evaluations and pre-transplant care. This study compared sarcopenia, via L3-psoas muscle index (L3-PMI), to frailty, via liver frailty index (LFI) and analyzed associated outcomes after liver transplantation (LT).
Methods
A retrospective review of consecutive LT-recipients with cross-sectional abdominal/pelvic imaging were reviewed over 5 years at a single transplant center.
Results
Four hundred and twenty-six patients underwent transplant during this study interval; 31% of patients were sarcopenic. Two hundred eight patients underwent LFI evaluation: 25% were frail, 59% were prefrail, and 16% were robust. Sarcopenic patients had higher LFI scores indicating greater frailty (p = 0.02). Both sarcopenia and LFI-frailty were associated with significantly higher MELD-Na scores. Length of post-LT hospital stay was increased in sarcopenic (mean 14 vs. nonsarcopenic 11 days, p = 0.02) and LFI-frail patients (mean 13 vs. 10 prefrail, 8 robust, p = 0.04). As a categorical variable, neither LFI-frailty nor sarcopenia were significantly associated with reduced survival at 1-year (robust 100%, prefrail 93.5%, frail 91.1%, p = 0.31) (nonsarcopenic 94.4%, sarcopenic 91.4%, p = 0.30). However, LFI score was significantly associated with mortality at 1-year (OR 2.133, p = 0.047).
Conclusions
Radiographic sarcopenia is a suitable proxy for in-person frailty assessment as both L3-PMI and LFI capture frail patients’ pre-LT. However, physical assessment with frailty better predicts 1-year mortality post-LT than the measurement of muscle mass.
期刊介绍:
Clinical Transplantation: The Journal of Clinical and Translational Research aims to serve as a channel of rapid communication for all those involved in the care of patients who require, or have had, organ or tissue transplants, including: kidney, intestine, liver, pancreas, islets, heart, heart valves, lung, bone marrow, cornea, skin, bone, and cartilage, viable or stored.
Published monthly, Clinical Transplantation’s scope is focused on the complete spectrum of present transplant therapies, as well as also those that are experimental or may become possible in future. Topics include:
Immunology and immunosuppression;
Patient preparation;
Social, ethical, and psychological issues;
Complications, short- and long-term results;
Artificial organs;
Donation and preservation of organ and tissue;
Translational studies;
Advances in tissue typing;
Updates on transplant pathology;.
Clinical and translational studies are particularly welcome, as well as focused reviews. Full-length papers and short communications are invited. Clinical reviews are encouraged, as well as seminal papers in basic science which might lead to immediate clinical application. Prominence is regularly given to the results of cooperative surveys conducted by the organ and tissue transplant registries.
Clinical Transplantation: The Journal of Clinical and Translational Research is essential reading for clinicians and researchers in the diverse field of transplantation: surgeons; clinical immunologists; cryobiologists; hematologists; gastroenterologists; hepatologists; pulmonologists; nephrologists; cardiologists; and endocrinologists. It will also be of interest to sociologists, psychologists, research workers, and to all health professionals whose combined efforts will improve the prognosis of transplant recipients.
