Clinical Relevancies of Sarcopenic Obesity in Patients with Metabolic Dysfunction-Associated Fatty Liver Disease (MASLD).

AIM

Sarcopenic obesity (SO) is associated with adverse outcomes in diseased patients. This study aimed to examine the prevalence and risks associated with SO, with a focus on the impact of SO on cardiovascular risk in patients with MASLD.

MATERIALS AND METHODS

In this cross-sectional study, patients with MASLD were prospectively enrolled. Through dual-energy X-ray absorptiometry (DXA) scans, their body compositions were analyzed to identify who had SO and osteopenia/osteoporosis. The primary aim is to investigate risks associated with SO, followed by analyzing the association between SO and cardiovascular disease (CVD).

RESULTS

Two hundred and twenty-three patients with MASLD were enrolled. The prevalence of SO was 47.1%, respectively. Patients coexisted with MASLD and SO had increased visceral adipose tissue (VAT), higher fatty liver index (FLI) and fibrosis 4 (FIB-4) score. Regression analysis revealed higher FLI and FIB-4 score, as well as history of hypertension, were risks associated with SO. The 10-year atherosclerotic cardiovascular disease (ASCVD) risk score was higher in patients coexisted with MASLD and SO compared to those without (10.1% vs. 7.3%, p = 0.006). Regression analysis showed that increased VAT and FIB-4 score were associated with raised risk of ASCVD.

CONCLUSION

Prevalence of SO in MASLD patients is considerable. The presence of SO also linked to higher risk of ASCVD. Therefore, the recognition of SO in patients with MASLD is important in clinical care.
