Handgrip strength is associated with 12-month survival in male patients suffering with advanced chronic liver disease.

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.

Specific nutrition evaluation of patients with advanced chronic liver disease: Development and validation.

BACKGROUND: Malnutrition is frequently identified in patients with advanced chronic liver disease (ACLD), and its early identification is necessary for effective nutrition treatment. The aim of this study was to develop and validate a tool for specific nutrition evaluation of patients with ACLD (SNE-ACLD). METHODS: SNE-ACLD was developed by consensus among experts using Delphi technique. The initial proposal for the SNE-ACLD had six domains (history of weight loss, changes in food intake, gastrointestinal symptoms, changes in functional capacity, presence of complications of liver disease, and a nutrition-focused physical examination) and 11 items. Fifteen experts participated in content validation. In a cross-sectional study design, the new tool was applied to 129 inpatients and outpatients from a gastrohepatology unit. Nutrition status was evaluated with SNE-ACLD and subjective global assessment by one researcher. Content validation and semantic analysis were obtained by content validity index. To verify accuracy of SNE-ACLD, the sensitivity, specificity, Youden index, and area under the receiver operating characteristic curve (AUC) were calculated. RESULTS: After five evaluative sequences conducted by experts, experts excluded the domain for history of weight loss and its respective item. The final version of SNE-ACLD consists of five domains and 10 items. The new instrument showed good accuracy in identifying any level of malnutrition (AUC = 0.83; 95% CI, 0.76-0.91) and severe malnutrition (AUC = 0.90; 95% CI, 0.79-1.00). CONCLUSION: SNE-ACLD can be used in nutrition assessment of patients with liver disease. Future works should investigate its agreement with other methods and its predictive value.

Effects of using symbiotics in the clinical nutritional evolution of patients with chronic pancreatitis: Study prospective, randomized, controlled, double blind.

Patients with chronic pancreatitis (CP) present malabsorption and changes in nutritional status. In this prospective, randomized, controlled, double-blinded, intervention study, developed at the Clinic of Pancreas, we aimed to assess whether the use of symbiotics changes the nutritional status, the biochemical data and the intestinal rate of these patients. The intervention consisted of administering 12 g/day of symbiotics composed of Lactobacillus casei, Lactobacillus rhamnosus, Lactobacillus acidophilus, Bifidobacterium bifidum and fructooligosaccharides to the intervention group and 12 g/day of medium absorption complex carbohydrate to the control group. The project was approved by the Ethics Committee of College of Technology and Science - FTC under the number process 0528-2008; reg. 498 e was registered under ClinicalTrials.gov. We evaluated 60 patients and the intervention lasted for 3 months, with monthly monitoring. A statistically significant reduction was observed in the results by day in relation to the initial frequency (x = 2.3) and the use of symbiotics in the second (x = 1.47) and third (x = 1.37) months (p = 0.001). In the control group, there was no significant change in this frequency (p = 0.157). The results showed an increase in the levels of hemoglobin (p < 0.001), hematocrit (p = 0.001), red blood cells (p < 0.001), total lymphocyte count (p < 0.002), serum magnesium (p < 0.001), albumin (0.001) and total serum cholesterol reduction (p < 0.001) with the use of symbiotics. The changes were not observed in the nutritional status of both groups. CONCLUSION: The use of symbiotics improved the clinical and laboratory profiles of the evaluated patients with CP, favoring the best clinical outcome, and may be a therapeutic option because of the low cost and therapeutic effectiveness in this population.

Effect of soy protein supplementation in patients with chronic hepatitis C: a randomized clinical trial.

AIM: To evaluate the effects of soy supplementation on insulin resistance, fatty liver and alanine aminotransferase (ALT) levels in non-diabetic patients with chronic hepatitis C (CHC). METHODS: In a prospective, randomized and single-blinded clinical trial, we compared patients with CHC who had casein as a supplement (n = 80) (control group), with patients who consumed a soy supplement diet (n = 80) [intervention group (IG)]. Both groups received 32 g/d of protein for 12 wk. RESULTS: Patients' baseline features showed that 48.1% were overweight, 43.7% had abdominal fat accumulation, 34.7% had hepatic steatosis and 36.3% had an homeostasis model assessment index of insulin resistance (HOMA-IR) ≥ 3.0. Descriptive analysis showed that protein supplementation diet reduced hepatic steatosis in both groups; however, significant reductions in ALT levels occurred in the soy group. Multiple regression modeling indicated that in the presence of severe fibrosis (F3/F4), γ glutamyl transferase elevation and high density lipoprotein (HDL) reduction, the intervention group had 75% less chance of developing hepatic steatosis (OR= 0.25; 95% CI: 0.06-0.82) and 55% less chance of presenting with an ALT level ≥ 1.5 × the upper limit of normal (ULN) (OR = 0.45, 95% CI: 0.22-0.89). Soy treatment did not have any effect on insulin resistance (OR = 1.92; 95% CI: 0.80-4.83), which might be attributed to the fact that the HOMA-IR values at baseline in most of our patients were in the normal range. Advanced hepatic fibrosis, an ALT level > 1.5 × ULN and visceral fat were predictors of an HOMA-IR ≥ 3. The IG group had a reduced risk of an ALT level > 1.5 × ULN. An HOMA-IR ≥ 3.0 and HDL < 35 mg/dL were also risk factors for increased ALT. CONCLUSION: Soy supplementation decreased ALT levels and thus may improve liver inflammation in hepatitis C virus (HCV) patients; it also reduced hepatic steatosis in a subgroup of patients but did not change insulin resistance. It should be considered in the nutritional care of HCV patients.
