Global Leadership Initiative on Malnutrition-defined malnutrition coexisting with visceral adiposity predicted worse long-term all-cause mortality among inpatients with decompensated cirrhosis.

Background/objectives: Malnutrition coexisting with abdominal adipose tissue accumulation bring a double burden on prognosis. More recently, the Global Leadership Initiative on Malnutrition (GLIM) has reached a novel consensus concerning the diagnostic criteria, that is, a two-step modality combining nutritional risk screening and subsequent phenotypic/etiologic parameters for comprehensive evaluation in hopes of harmonizing the malnutrition diagnosis. We aimed to elucidate their synergistic impact among inpatients with decompensated cirrhosis concerning long-term mortality.

Subjects/methods: Malnutrition, visceral obesity, and visceral adiposity were defined by the Global Leadership Initiative on Malnutrition (GLIM), visceral fat area (VFA), and visceral to subcutaneous adipose tissue area ratio (VSR) on computed tomography, respectively. Accordingly, the patients were categorized into different groups given their nutritional status and visceral obesity/adiposity. Multivariate Cox regression was performed to identify independent risk factors associated with 1-year all-cause mortality. Kaplan-Meier curves with log-rank tests were compared among distinct groups.

Results: Totally, 295 patients were recruited. GLIM, VFA, and VSR identified 131 (44.4%), 158 (53.6%), and 59 (20%) patients with malnutrition, visceral obesity and visceral adiposity, respectively. Malnutrition coexisted with visceral obesity in 55 (MO group) relative to visceral adiposity in 40 patients (MA group). Multivariate Cox analysis showed that MA (hazard ratio: 2.48; 95% confidence interval: 1.06, 5.79; P = 0.036) was independently associated with dire outcome rather than MO. Moreover, patients with cirrhosis in the MA group had the worst survival status when compared with other groups (log-rank test: P < 0.001).

Conclusions: The current study indicated that coexisting GLIM-defined malnutrition and VSR-defined visceral adiposity were in relation to worse long-term mortality among inpatients. It is imperative to delicately manage nutritional status and provide personalized treatment in this vulnerable subgroup for achieving better prognosis.
