Abstract : Background: Sarcopenia is strongly associated with poor outcome in cirrhosis. There are little prospective data that sarcopenia influences outcomes in critically ill cirrhotics (CICs). Computed tomography (CT) is the gold standard for sarcopenia assessment in the intensive care unit (ICU), as it is independent of hydration status. Aim: This study aims to assess the prevalence of sarcopenia and study its impact on clinical outcomes in CICs. Methods: In this prospective observational study, CICs admitted to the liver ICU were enrolled, if meeting inclusion (age 18-70 years, abdominal CT scan within three months before ICU admission) and exclusion criteria (survival likely to be <24 h, coexisting chronic diseases). Clinical, hemodynamic, biochemical, and nutritional parameters, including length of stay (LOS), duration of mechanical ventilation (MV), development of new-onset infections (NOI), incidence of new-onset acute kidney injury (AKI), and overall survival, were recorded. CT images at the L3 level were analyzed using Slice-O-Matic V4.3 software to assess the skeletal muscle index (SMI) expressed as skeletal muscle area (cm2)/height (m2). Sarcopenia was defined if SMI was <50 cm2/m2 - males and <39 cm2/m2 - females. Data were analyzed using SPSS version 22. Results: Altogether 111 patients (M-83.8%; age 48.4±11.3 years; etiology: Alcohol - 56 [50.5%], non-alcoholic steatohepatitis - 27 [24.3%], viral - 12 [10.8%], and others - 16 [14.4%]; Child-Turcotte-Pugh - 11.9±1.8; model for end-stage liver disease - 27.8±7.3; sequential organ failure assessment - 10.5±4.1; APACHE - 23±8; and MV - 54 [48.6%]) were enrolled. Of these, 76 (68.5%) were sarcopenic and 35 (31.5%) non-sarcopenic. Sarcopenic CICs had higher overall mortality (72.4%) compared to non-sarcopenics (40%) (P=0.001, OR [95% CI] - 3.93 [1.69-9.12]), and higher prevalence of sepsis at ICU admission (53.9% vs. 31.4%, P=0.027, OR [95% CI] - 1.7 [1.0-2.92]) than non-sarcopenics. LOS, duration of MV, incidence of NOI, and development of new-onset AKI were comparable between groups. Multivariate binary logistic regression showed that sarcopenia, sepsis, and APACHE II score were independently associated with mortality. Conclusion: Two-thirds of CICs have sarcopenia at ICU admission, making them 1.7 times more susceptible to sepsis and increasing the risk of mortality by almost 4-fold in the ICU. Relevance for patients: Almost 70% of patients with chronic liver disease admitted to the ICU have low muscle mass (sarcopenia). The presence of sarcopenia per se makes them highly prone to infections and increases the chances of death by almost 4-fold; thus, highlighting the importance of nutrition optimization in this patient group.
