BackgroundAlthough malnutrition and sarcopenia are prevalent in cirrhosis, their impact on outcomes following liver transplantation is not well documented.MethodsThe associations of nutritional status and sarcopenia with post‐transplant infections, requirement for mechanical ventilation, intensive care (ICU) and hospital stay, and 1 year mortality were assessed in 232 consecutive transplant recipients. Nutritional status and sarcopenia were assessed using the Royal Free Hospital‐Global Assessment (RFH‐GA) tool and the L3‐psoas muscle index (L3‐PMI) on CT, respectively.ResultsA wide range of RFH‐SGA and L3‐PMI were observed within similar Model for End‐stage Liver Disease (MELD) sub‐categories. Malnutrition and sarcopenia were independent predictors of all outcomes. Post‐transplant infections were associated with MELD (OR = 1.055, 95%CI = 1.002–1.11) and severe malnutrition (OR = 6.55, 95%CI = 1.99–21.5); ventilation > 24 h with MELD (OR = 1.1, 95%CI = 1.036–1.168), severe malnutrition (OR = 8.5, 95%CI = 1.48–48.87) and suboptimal donor liver (OR = 2.326, 95%CI = 1.056–5.12); ICU stay > 5 days, with age (OR = 1.054, 95%CI = 1.004–1.106), MELD (OR = 1.137, 95%CI = 1.057–1.223) and severe malnutrition (OR = 7.46, 95%CI = 1.57–35.43); hospital stay > 20 days with male sex (OR = 2.107, 95%CI = 1.004–4.419) and L3‐PMI (OR = 0.996, 95%CI = 0.994–0.999); 1 year mortality with L3‐PMI (OR = 0.996, 95%CI = 0.992–0.999). Patients at the lowest L3‐PMI receiving suboptimal grafts had longer ICU/hospital stay and higher incidence of infections.ConclusionsMalnutrition and sarcopenia are associated with early post‐liver transplant morbidity/mortality. Allocation indices do not include nutritional status and may jeopardize outcomes in nutritionally compromised individuals.

We developed and validated a new accurate model for GFR assessment in cirrhosis, the Royal Free Hospital cirrhosis GFR, using readily available variables; this remains to be tested and incorporated in prognostic scores in patients with cirrhosis. (Hepatology 2017;65:582-591).

There is ongoing evidence that vitamin D is related to the pathophysiology of cirrhosis. Although the incidence of vitamin D deficiency in chronic liver diseases and cirrhosis is strongly documented, its pathogenic association with advanced liver fibrosis remains controversial. There is evidence of a significant relation of 25(OH)D levels with the degree of liver dysfunction, considering that an inverse correlation of 25(OH)D levels with both Child-Pugh score and Model for End-Stage Liver Disease has been reported. In addition, vitamin D deficiency has been shown to increase the risk for overall mortality and infections in patients with cirrhosis. Vitamin D deficiency has been also associated with advanced stages of hepatocellular carcinoma and poor prognosis. Finally, there are studies suggesting that patients with chronic hepatitis C and normal vitamin D levels have higher virological response to treatment. However, there are not enough studies conducted in cirrhotic-only populations. The association between vitamin D and cirrhosis demonstrates a great potential for clinical application. The relation between vitamin D deficiency and the degree of liver function, degree of fibrosis and infectious complications could support its use as a prognostic index and a diagnostic tool.
