The influence of muscle performance and fatigue on prognosis in patients with compensated liver disease

Abstract

Abstract Background Poor muscle function is associated with a negative prognosis in advanced liver disease but the impact in compensated chronic liver disease is unknown. Similar prognostic uncertainty applies to fatigue. We aimed to assess the prognostic value of muscle performance and fatigue in a cohort of patients with compensated chronic liver disease. Methods We followed 241 patients with compensated chronic liver disease included in a study between 2010 and 2014. Subjects were 52 ± 15 years (mean ± SD; 134 females). All subjects performed four muscle function tests: “Timed Up and Go” test, walking speed, handgrip strength, and standing heel-rises. Fatigue was evaluated by fatigue impact scale. Follow up data was acquired through hospital records and registries. Results During follow up of 6.75 ± 1.4 years, 13 patients died (5.5%) and 11 (4.5%) patients underwent liver transplantation. A timed up and go over 10 s was not significantly associated with a lower survival (Kaplan-Meier, log rank test p = 0.132), or with transplant free survival (p = 0.543), Fig. 3. It was also not specifically associated with liver related causes of death (p = 0.597). The other physical functioning tests and fatigue were not significantly associated with mortality or transplant-free survival (p > 0.05 for all) except for maximal walking speed (2.2 vs. 1.9 m/s, p = 0.007). Conclusions Our study suggests that muscle function and fatigue are not key prognostic factors in compensated chronic liver disease. However, further confirmation in future studies is needed.
