ABSTRACT

OBJECTIVES: The Global Leadership Initiative on Malnutrition (GLIM) is a framework aiming to standardize malnutrition diagnosis. However, it still needs to be validated, in particular for patients with chronic liver disease. This study aimed to validate the GLIM criteria in patients with liver cirrhosis awaiting liver transplant (LTx). METHODS: This was a retrospective observational study carried out with adult patients on the waiting list for LTx, consecutively evaluated between 2006 and 2021. The phenotypic criteria were unintentional weight loss, low body mass index, and reduced muscle mass (midarm muscle circumference [MAMC]). The etiologic criteria were high Model for End-Stage Liver Disease (MELD) and MELD adjusted for serum sodium (MELD-Na) scores, the Child-Pugh score, low serum albumin, and low food intake and/or assimilation. Forty-three GLIM combinations were tested. Sensitivity (SE), specificity (SP), positive and negative predictive values, and machine learning (ML) techniques were used. Survival analysis with Cox regression was carried out. RESULTS: A total of 419 patients with advanced liver cirrhosis were included (median age, 52.0 y [46-59 y]; 69.2% male; 68.8% malnourished according to the Subjective Global Assessment [SGA]). The prevalence of malnutrition by the GLIM criteria ranged from 3.1% to 58.2%, and five combinations had SE or SP >80%. The MAMC as a phenotypic criterion with MELD and MELD-Na as etiologic criteria were predictors of mortality. The MAMC and the presence of any phenotypic criteria associated with liver disease parameters and low food intake or assimilation were associated with malnutrition prediction in ML analysis. CONCLUSIONS: The MAMC and liver disease parameters were associated with malnutrition diagnosis by SGA and were also predictors of 1-y mortality in patients with liver cirrhosis awaiting LTx.

ABSTRACT

BACKGROUND: Chronic liver disease is associated with malnutrition that negatively impacts a patient's health-related quality of life (HRQoL). AIM: To evaluate the short-term effect of whey protein supplementation on the HRQoL and nutritional and functional status of patients waiting for liver transplantation. METHODS: This was a double-blind randomized clinical trial with patients waiting for liver transplantation who were randomized into two groups: WP (whey protein supplementation) and the control (casein supplementation). Both groups received 40 g (20 g in the morning and 20 g in the evening) for 15 days. Nutritional and functional status were evaluated. Energy balance was calculated as the difference between energy intake (24-hour recall) and total energy expenditure (assessed by indirect calorimetry). The chronic liver disease questionnaire was used to assess HRQoL. All measurements were performed before and after the intervention. RESULTS: Fifty-six patients were evaluated. Malnutrition was present in 56.9%, and it was directly associated with a poor HRQoL (p<0.05). No improvement on the nutritional and functional status was observed, in either group after protein supplementation. HRQoL improved after WP and casein supplementation, with no differences between groups (p>0.05). Patients who met protein requirements and had a positive energy balance demonstrated a higher HRQoL score (4.9, p<0.05), without between-group differences. CONCLUSION: Malnutrition substantially reduces HRQoL. Short-term WP or casein supplementation improved similarly the HRQoL.

RESUMO Racional: A doença hepática crônica está associada à desnutrição que afeta negativamente a qualidade de vida relacionada à saúde (QVRS). Objetivo: Avaliar o efeito da suplementação aguda de proteína do soro de leite na QVRS e no estado nutricional e funcional dos pacientes em lista de espera para o transplante hepático. Métodos: Ensaio clínico randomizado com pacientes à espera do transplante hepático que foram randomizados em dois grupos: PS (suplementação com proteína do soro de leite) e Controle (suplementação com caseína). Ambos os grupos receberam 40 g das proteínas (20 g pela manhã e 20 g à noite) por 15 dias. O estado nutricional e funcional foi avaliado. O balanço energético foi calculado como a diferença entre a ingestão energética (recordatório de 24 horas) e o gasto energético total (avaliado por calorimetria indireta). O questionário de doença hepática crônica (CDLQ) foi utilizado para avaliar a QVRS. Todas as medidas foram realizadas antes e após a intervenção. Resultados: Cinquenta e seis pacientes foram avaliados. A desnutrição esteve presente em 56,9% e, diretamente associada à baixa QVRS (p<0,05). A suplementação, com ambas as proteínas, não alterou o estado nutricional e funcional dos pacientes (p>0,05). Entretanto, a QVRS melhorou após a suplementação com PS e caseína, sem diferenças entre os grupos (p>0,05). Pacientes que alcançaram as necessidades proteicas e com balanço energético positivo tiveram maior escore de QVRS (4,9; p<0,05), sem diferenças entre os grupos (p>0,05). Conclusão: A desnutrição reduz substancialmente a QVRS. A suplementação aguda com PS ou caseína melhorou de forma similar a QVRS.
