RESUMO
Cirrhosis is characterised by a prolonged asymptomatic period in which the inflammation persists, increasing as the disease progresses. Characteristic of this is the increase in pro-inflammatory cytokines and pro-oxidant molecules which are determining factors in the development of multiple organ dysfunction. In the early development of cirrhosis, splanchnic arterial vasodilation, activation of vasoconstrictor systems (renin-angiotensin-aldosterone) and the sympathetic nervous system (noradrenaline) bring about bacterial translocation and systemic dissemination via portal circulation of bacterial products, and molecular patterns associated with damage, which exacerbate the systemic inflammation present in the patient with cirrhosis. Albumin is a molecule that undergoes structural and functional changes as liver damage progresses, affecting its antioxidant, immunomodulatory, oncotic and endothelial stabilising properties. Our knowledge of the properties of albumin reveals a molecule with multiple treatment options in patients with cirrhosis, from the compensated then decompensated phases to multiple organ dysfunction. Its recognised uses in spontaneous bacterial peritonitis, post-paracentesis circulatory dysfunction, acute kidney injury and hepatorenal syndrome are fully validated, and a treatment option has opened up in decompensated cirrhosis and in acute-on-chronic liver disease.

Introduction: Introduction: malnutrition and sarcopenia are frequent in the population with liver cirrhosis and have a negative impact on the performance status and life expectancy of these patients. There are multiple assessment tools for malnutrition and sarcopenia in cirrhosis. Objective: to assess malnutrition and sarcopenia in liver cirrhosis and to compare the accuracy of diagnostic tools in this population. Method: a cross-sectional analytical study was conducted with convenience sampling by using continuous inclusion of patients with liver cirrhosis in a tertiary care center during December 2018 to May 2019. The nutritional assessment was carried out with arm anthropometry, body mass index (BMI), and the algorithm of the Royal Free Hospital Subjective Global Assessment (RFH-SGA). For the evaluation of sarcopenia, the hand grip strength test with a hand dynamometer was applied. The results were reported in measures of central tendency expressed in frequency and percentage. Results: a total of 103 patients were included with a predominance of the male gender (79.6 %) and a mean age of 51 years (± 10). The etiology of liver cirrhosis corresponded more frequently to alcohol consumption (68 %) and most of the patients were Child-Pugh C (57.3 %) with a mean MELD of 21.9 (± 8.9). A mean BMI with dry weight of 25.2 kg/m2 was reported, and with respect to the WHO classification by BMI, 7.8 % were underweight and 59.2 % were malnourished by RFH-SGA. Sarcopenia was present in 88.3 % using the hand grip strength test, for which a mean of 18.99 kg was found. A Kendall's Tau-b rank correlation coefficient was performed between BMI and RFH-SGA, which showed no statistically significant association, as well as between mean arm muscle circumference percentiles and hand grip strength. Conclusions: global assessment in liver cirrhosis should include screening for malnutrition and sarcopenia, for which validated, accessible and safe application tools should be used, such as anthropometric assessment, RFH-SGA, and hand grip strength.
Introducción: Introducción: la malnutrición y la sarcopenia son frecuentes en la población con cirrosis hepática y generan un impacto negativo en el estado funcional y la esperanza de vida de estos pacientes. Existen múltiples herramientas para la valoración de la malnutrición y la sarcopenia en los pacientes con cirrosis hepática. Objetivo: valorar la malnutrición y la sarcopenia en la cirrosis hepática y comparar distintas herramientas diagnósticas aplicables en esta población. Método: se realizó un estudio analítico de corte transversal con muestreo a conveniencia mediante inclusión continua de pacientes con cirrosis hepática en un hospital de tercer nivel durante diciembre de 2018 a mayo de 2019. Se realizó la valoración nutricional con la antropometría del brazo, el índice de masa corporal (IMC) y el algoritmo del Royal Free Hospital Subjetive Global Assessment (RFH-SGA). Para la valoración de la sarcopenia se aplicó la fuerza de agarre de la mano con un dinamómetro. Los resultados se reportaron en medidas de tendencia central expresadas en frecuencia y porcentaje. Resultados: se incluyeron un total de 103 pacientes, predominando el género masculino (79,6 %), con una edad media de 51 años. La etiología más frecuente de la cirrosis hepática fue el consumo de alcohol (68 %), predominando la clase Child-Pugh C (57,3 %) con una media de MELD de 21,9 (± 8,9). Se reportó una media de IMC con peso seco de 25,2 kg/m2 y, respecto a la clasificación de la OMS, un 7,8 % se encontraban en bajo peso y un 59,2 % en malnutrición según la RFH-SGA. Un 88,3 % presentó sarcopenia al utilizar la fuerza de agarre de la mano, cuyo valor medio fue de 18,99 kg. Se realizó una correlación con Tau b de Kendall entre IMC y RFH-SGA sin evidenciarse ninguna asociación significativa, al igual que entre los percentiles de la circunferencia muscular media de brazo (MAMC) y la fuerza de agarre de la mano. Conclusiones: la valoración integral de la cirrosis hepática debe incluir el escrutinio de la malnutrición y la sarcopenia, existiendo herramientas de fácil acceso y aplicación segura validadas en esta población, como la valoración antropométrica, el RFH-SGA y la fuerza de agarre de la mano.
