Background: Advanced chronic liver disease (ACLD) patients are usually malnourished, and both conditions in combination increase the likelihood of unfavourable clinical outcomes. Handgrip strength (HGS) has been suggested as a relevant parameter for nutritional assessment and predictor of adverse clinical outcomes in ACLD. However, the HGS cut-off values for ACLD patients have not yet been reliably established. The aims of this study were to preliminarily identify HGS reference values in a sample population of ACLD male patients and to assess their association with survival over a 12-month follow-up period., Methods: This was a prospective observational study with preliminary analysis of outpatients and inpatients. A total of 185 male patients with a medical diagnosis of ACLD met the inclusion criteria and were invited to participate in the study. The physiological variation in muscle strength related to the age of the individuals included in the study was considered to obtain cut-off values., Results: After categorising HGS by age group (adults: 18-60 years; elderly: ≥60 years), the reference values obtained were 32.5 kg for the adults and 16.5 kg for the elderly. During the 12-month follow-up, 20.5% of the patients died, and 76.3% of those had been identified with reduced HGS., Conclusions: Patients with adequate HGS showed significantly higher 12-month survival than those with reduced HGS within the same period. Our findings show that HGS is an important predictive parameter for clinical and nutritional follow-up in ACLD male patients., (© 2023 The British Dietetic Association Ltd.)

Background: Different nutritional screening instruments can be used to identify the risk of malnutrition in advanced chronic liver disease patients. The present study aimed to evaluate and compare two nutrition screening tools with the Global Leadership Initiative on Malnutrition (GLIM) diagnostic criteria for malnutrition in patients with advanced chronic liver disease., Methods: Two nutritional screening tools, Nutritional Risk Screening 2002 (NRS-2002) and Royal Free Hospital Nutritional Prioritizing Tool (RFH-NPT), were assessed for 166 patients with liver cirrhosis. We compared medium/high nutritional risk screening with the diagnosis of malnutrition, using the GLIM criteria as the reference standard., Results: According to the GLIM criteria, 57.3% of the patients were malnourished. NRS and RFH-NPT identified, respectively, 36.1% and 52.4% of patients with nutritional risk. RFH-NPT presented better agreement with the diagnosis according to GLIM criteria (k = 0.64; 95% confidence interval = 0.52-0.75), higher sensitivity (80%), higher negative predictive value (79%) and larger area under the curve (82.3%) compared to the NRS., Conclusions: RFH-NPT, when compared with the GLIM method, has substantial agreement in identifying nutritional risk, good sensitivity and good value for diagnosing malnutrition in patients with advanced chronic liver disease., (© 2020 The British Dietetic Association Ltd.)

Background: Insulin resistance promotes liver disease progression and may be associated with a lower response rate in treated hepatitis C virus (HCV) infected patients. n-3 polyunsaturated fatty acid (PUFA) supplementation may reduce insulin resistance. The present study aimed to evaluate the effect of n-3 PUFA supplementation on insulin resistance in these patients., Methods: In a randomised, double-blind clinical trial, 154 patients were screened. After applying inclusion criteria, 52 patients [homeostasis model assessment index of insulin resistance (HOMA-IR ≥2.5)] were randomly divided into two groups: n-3 PUFA (n = 25/6000 mg day(-1) of fish oil) or control (n = 27/6000 mg day(-1) of soybean oil). Both groups were supplemented for 12 weeks and underwent monthly nutritional consultation. Biochemical tests were performed at baseline and after intervention. Statistical analysis was performed using the Wilcoxon Mann-Whitney test for comparisons and the Wilcoxon test for paired data. Statistical package r, version 3.02 (The R Project for Statistical Computing) was used and P < 0.05 (two-tailed) was considered statistically significant., Results: Comparisons between groups showed that n-3 PUFA supplementation was more effective than the control for reducing HOMA-IR (P = 0.015) and serum insulin (P = 0.016). The n-3 PUFA group not only showed a significant reduction in HOMA-IR 3.8 (3.2-5.0) versus 2.4 (1.8-3.3) (P = 0.002); serum insulin 17.1 (13.8-20.6) μIU mL(-1) versus 10.9 (8.6-14.6) μIU mL(-1) (P = 0.001); and glycated haemoglobin 5.4% (5.0-5.7%) versus 5.1% (4.8-5.6%) (P = 0.011), but also presented an increase in interleukin-1 97.5 (0.0-199.8) pg mL(-1) versus 192.4 (102.2-266.8) pg mL(-1) (P = 0.003) and tumour necrosis factor 121.2 (0.0-171.3) pg mL(-1) versus 185.7 (98.0-246.9) pg mL(-1) (P = 0.003)., Conclusions: n-3 PUFA supplementation reduces insulin resistance in genotype 1 HCV infected patients., (© 2015 The British Dietetic Association Ltd.)
