Mayr Yanyan Chen Aaron P. Thrift Graeme A. Macdonald Ingrid J. Hickman Clinical Transplantation ABSTRACTIntroductionMyosteatosis is fat infiltration within skeletal muscle. The impact of myosteatosis on physical function and clinical outcomes in patients referred for liver transplantation (LT) is unclear. We explored associations between myosteatosis and sarcopenia, frailty, physical function, and pre‐ and early post‐LT outcomes.MethodsMyosteatosis was assessed by computed tomography (CT) in 237 patients referred for LT (March 2018 to September 2022). Chi‐square/Fishers exact tests and multivariable regression compared myosteatosis and sarcopenia, frailty (liver frailty index), physical function (short physical performance battery, SPPB); and associations with pre‐LT unplanned hospitalizations, post‐LT surgical complications (Clavien–Dindo grade ≥ 3), and LT admission length of stay (LOS). Kaplan–Meier and Cox‐proportional hazards models explored myosteatosis and time to LT and unplanned admission. Fine–Gray model evaluated the competing risks of receiving an LT.ResultsMyosteatosis was present in 74 (31%) patients. Patients with myosteatosis were 2.5 times (95% confidence interval [CI] 1.1–5.7, p = 0.03) more likely to be frail, and 3.0 times (95% CI 1.6–5.6, p < 0.001) more likely to have a poor physical function (SPPB ≤ 9/12) than those without myosteatosis. Patients with myosteatosis versus those without were more likely to have a pre‐LT unplanned hospitalization (51% vs. 36%, p = 0.03), but significance was lost after adjusting for age, sex, Model for End‐stage Liver Disease (MELD), and the presence of hepatocellular carcinoma. Myosteatosis did not impact the likelihood of receiving an LT (p = 0.39), post‐LT complications (p = 0.93), or LOS in intensive care unit (ICU) (p = 0.66) or hospital (p = 0.34).ConclusionsMyosteatosis is prevalent in patients referred for LT and is associated with impaired physical function. Using existing CTs to assess myosteatosis in practice may help identify physically compromised patients. 10.1111/ctr.70034 http://onlinelibrary.wiley.com/termsAndConditions#vor |
