RESUMEN

BACKGROUND: Physical exercise (PE) has been proven to be beneficial in patients with cirrhosis; effects in cognitive function and cerebral hemodynamics, are yet to be explored. AIM: To evaluate the effects of a PE program (LFN-exercise protocol) in hepatic/cerebral hemodynamics. METHODS: Randomized open clinical trial in patients with cirrhosis; Control: Diet(n = 13),Intervention: Diet + exercise(n = 14) for 12 weeks. Patients received an educational session, mental exercises (printed book and sudoku), and high-protein diet. Exercise intervention consisted of walking 4 times/week with an intensity rated between 12 and 14 on the Borg scale, monitored through bracelet accelerometers. Patients received weekly text messages to encourage adherence and had monthly in-person visits. RESULTS: Patients were mainly Child-Pugh A(88.9 %), median MELD 8(8-10), mean age 53±8 years. In the exercise group the number of steps increased from 9667±3008 to 11,931±4463 (p = 0.002), vs 8004±3224 to 8903±3504 (p = 0.053) in controls. Exercise decreased HVPG from 11(8-14) to 8(6-11)mmHg (p = 0.032) vs no change in the control group from 14(12-16) to 15(11-17)mmHg (p = 0.959). Intervention group showed better cerebral hemodynamics, cognitive function, nutritional status and quality of life after the intervention. Adherence was >90 %, with no adverse events. CONCLUSION: The LFN-exercise protocol improves portal hypertension, cerebral hemodynamics and cognitive function, as well as nutritional status and quality of life. GOV NUMBER: NCT03932552.

RESUMEN

BACKGROUND: The implementation of nutritional strategies targeting several variables at once could benefit patients with cirrhosis. Non-alcoholic beer has different compounds that exert antioxidant, anti-inflammatory and nutritional properties. AIM: To evaluate the effect of diet + exercise and non-alcoholic beer on nutritional status, endothelial function and quality of life in patients with cirrhosis. METHODS: In this randomized open clinical trial, patients with cirrhosis were randomized into two groups: The intervention (non-alcoholic beer + diet + exercise) and control (water + diet + exercise) group. Treatment consisted of 330 mL non-alcoholic beer/day or the same amount of water, plus an individualized dietary plan and an exercise program with a pedometer-based bracelet to reach at least 5000 steps/d and > 2500 above the baseline during 8 wk. Endothelial function (flow-mediated dilation, plethysmography), biochemical and nutritional variables and quality of life (CLDQ) were evaluated. RESULTS: Forty-three patients were included in the study, 21 in the control group and 22 in the intervention group. The mean age was 53.5 ± 7.8 years, 60% were women, the median MELD score was 8 (7-10) and most patients were Child-Pugh A (88%). Adherence to the interventions was > 90% in both groups, there were no adverse events and all biochemical parameters remained stable in both groups. Endothelial function improved in both groups. All measured nutritional parameters improved in the intervention group, compared to only 2 in the control group and quality of life improved in both groups; however, more domains improved in the intervention group. CONCLUSION: The intervention consisting of non-alcoholic beer, diet and exercise seems to be safe and well tolerated in patients with cirrhosis, and shows improvement in nutritional status, endothelial function, and quality of life. These results need to be further confirmed.

RESUMEN

AIM: Evaluate the association between phase angle and the development of hepatic encephalopathy in the long-term follow-up of cirrhotic patients. METHODS: This was a prospective cohort study. Clinical, nutritional and biochemical evaluations were performed. Mann-Whitney's U and χ2 tests were used as appropriate. Kaplan-Meier curves and Cox proportional Hazards analysis were used to evaluate the prediction and incidence of hepatic encephalopathy. RESULTS: Two hundred and twenty were included; the most frequent etiology of cirrhosis was hepatitis C infection, 52% of the patients developed hepatic encephalopathy (18.6% covert and 33.3% overt); the main precipitating factors were infections and variceal bleeding. Kaplan-Meier curves showed a higher proportion of HE in the group with low phase angle (39%) compared to the normal phase angle group (13%) (P = 0.012). Furthermore, creatinine and phase angle remained independently associated to hepatic encephalopathy in the Cox regression multivariate analysis [hazard ratio = 1.80 (1.07-3.03)]. CONCLUSION: In our cohort of patients low phase angle was associated with an increased incidence of hepatic encephalopathy. Phase angle is a useful nutritional marker that evaluates cachexia and could be used as a part of the integral assessment in patients with cirrhosis.

RESUMEN

BACKGROUND: Malnutrition is a frequent complication of cirrhosis and it has been associated to more severe disease and development of complications. Phase angle is a bedside reliable tool for nutritional assessment based on conductivity properties of body tissues. AIM: To evaluate the association between malnutrition assessed through phase angle and mortality in patients with liver cirrhosis. METHODS: We performed a prospective cohort study in a tertiary care centre; 249 patients were enrolled with 48 months of follow-up. Clinical, nutritional (malnutrition = phase angle ≤ 4.9°) and biochemical evaluations were performed. Student's t-test and χ(2) method were used as appropriate. Kaplan-Meier curves and multivariate Cox regression were used to evaluate mortality. RESULTS: Mean follow-up was 33.5 months. Survival analysis showed higher mortality in the malnourished group compared to the well-nourished group (p = 0.076), Kaplan-Meier curves were further stratified according to compensated and decompensated status showing higher mortality in compensated patients according to Child-Pugh (p = 0.002) and Model for End-Stage Liver Disease score (p = 0.008) when malnutrition was present. Multivariate analysis showed that malnutrition was independently associated with mortality (HR = 2.15, 1.18-3.92). CONCLUSIONS: In our cohort, malnutrition was independently associated with mortality. This is the first study showing higher mortality in malnourished compensated cirrhotic patients.
