Rationale And Objectives:
To define sarcopenic obesity (SaO) among chronic liver disease (CLD) patients via CT and MRI, and assess its impact on liver disease severity.
Materials And Methods:
CLD patients referred from the Gastroenterology and Hepatology Department diagnosed as chronic hepatitis B (N:101), cirrhosis (N:110), and hepatocellular carcinoma (N:169) with available information on body height, weight, Child-Pugh and MELD scores within 2 weeks of CT or MRI scanning were included in the study. Cross-sectional examinations were retrospectively evaluated for skeletal muscle index (SMI) and visceral adipose tissue area (VATA). The disease severity was assessed by Child-Pugh and MELD scoring.
Results:
The rate of sarcopenia and SaO in the cirrhotic patients was higher than that in the chronic hepatitis B patients (p <0.033 and p < 0.004, respectively). The rate of sarcopenia and SaO in HCC patients was higher than that in the chronic hepatitis B patients (p <0.001 and p <0.001, respectively). Sarcopenic patients in Chronic hepatitis B, cirrhotic, and HCC groups had higher MELD scores than nonsarcopenic patients (p <0.035, p <0.023, and p <0.024, respectively). Despite finding a similar increase in Child-Pugh scores in cirrhotic and HCC sarcopenic patients, results were statistically insignificant (p <0.597 and p <0.688). HCC patients with SaO had higher MELD scores than patients with other body composition catagories (p <0.006). Cirrhotic patients with SaO had higher MELD scores than nonsarcopenic obese patients (p <0.049). Chronic hepatitis B patients with obesity had low MELD scores (p <0.035). Cirrhotic and HCC patients with obesity had higher MELD scores (p <0.01 and p <0.024, respectively). Cirrhotic and HCC patients with obesity had higher Child-Pugh scores than nonobese patients but only HCC patients showed statistically significance (p <0.480 and p <0.001).
Conclusion:
Radiologic evaluation of SaO and harmonizing body composition with MELD scoring is critical in CLD management.
