2D shear wave elastography of the rectus femoris muscle in patients with cirrhosis: Feasibility and clinical findings. A pilot study - 02/03/23
Highlights |
• | RFMS using 2D-SWE is feasible and reproducible in patients with cirrhosis. |
• | RFMS is highly variable within frailty classes. |
• | Thickness of VM and RF correlate with LFI. |
• | These measurements could represent a complementary assessment for frailty. |
Abstract |
Background and aims |
Frailty is frequent in cirrhosis and associated with skeletal muscle abnormalities and worse prognosis. 2D shear-wave elastography (2D-SWE) could mirror biomechanical properties of skeletal muscle reflecting muscle quality. However, there is no data on 2D-SWE on skeletal muscle stiffness assessment in cirrhosis and on frailty.
Methods |
Outpatients with cirrhosis were prospectively included in a single center. Skeletal muscle stiffness was studied at the rectus femoris by 2D-SWE. Ileo-psoas area and index (area/height2), and antero-posterior diameter of rectus femoris (RF) was measured on ultrasound.
Results |
We included 44 patients (24 male, age 59 [IQR 49–66]) with a median liver frailty index (LFI) of 3.7 (IQR 3.2–4.0). Measurement of RF muscle stiffness (RFMS) was feasible in all with high inter-measurement reproducibility. RFMS did not correlate with LFI, liver function and skeletal muscle diameters. Ileo-psoas index was lower in frail patients (1.7 vs 1.0 cm2/m2, p = 0.024). RF antero-posterior diameter inversely correlated with LFI (r -0.578: p<0.001).
Conclusion |
RFMS by 2D-SWE is feasible and reproducible in cirrhosis and is independent of liver function and LFI, and warrants further studies in this setting. RF antero-posterior diameter could be reported as an objective parameter mirroring sarcopenia and frailty.
