ABSTRACT

BACKGROUND: Liver cirrhosis is a worldwide burden and is associated with poor clinical outcomes, including increased mortality. The beneficial effects of dietary modifications in reducing morbidity and mortality are inevitable. AIM: The current study aimed to evaluate the potential association of dietary protein intake with the cirrhosis-related mortality. METHODS: In this cohort study, 121 ambulatory cirrhotic patients with at least 6 months of cirrhosis diagnosis were followed-up for 48 months. A 168-item validated food frequency questionnaire was used for dietary intake assessment. Total dietary protein was classified as dairy, vegetable and animal protein. We estimated crude and multivariable-adjusted hazard ratios (HRs) with 95% confidence intervals (CIs), applying Cox proportional hazard analyses. RESULTS: After full adjustment for confounders, analyses showed that total (HR = 0.38, 95% CI = 0.2-1.1, p trend = 0.045) and dairy (HR = 0.38, 95% CI = 0.13-1.1, p trend = 0.046) protein intake was associated with a 62% lower risk of cirrhosis-related mortality. While a higher intake of animal protein was associated with a 3.8-fold increase in the risk of mortality in patients (HR = 3.8, 95% CI = 1.7-8.2, p trend = 0.035). Higher intake of vegetable protein was inversely but not significantly associated with mortality risk. CONCLUSION: A comprehensive evaluation of the associations of dietary protein intake with cirrhosis-related mortality indicated that a higher intakes of total and dairy protein and a lower intakes of animal protein are associated with a reduced risk of mortality in cirrhotic patients.

ABSTRACT

Since conducting a long-term randomised clinical trial is not logical and feasible to find the optimum dosage of salt intake in patients with cirrhosis, cohort studies are the best design to assess the long-term effects of dietary salt on the survival of cirrhotic patients. This cohort study aimed to evaluate the association between dietary intake of salt and mortality risk in cirrhotic patients. The present study was designed as a cohort in three referral hospitals in Iran in 2018. One hundred and twenty-one patients aged between 20 and 70 years with established cirrhosis were recruited. Dietary intakes, demographic data and disease severity were evaluated at the baseline. Participants were followed up annually. Crude survival was greater in patients with low-to-moderate salt consumption rather than in those with high consumption, and in non-consumers [34⋅26 (95 % CI 33⋅04, 35⋅49) v. 30⋅41 (95 % CI 27⋅13, 33⋅69) v. 32⋅72 (95 % CI 30⋅63, 34⋅80), P = 0⋅028; log-rank test]. Using the Cox proportional hazard model, it was shown that the risk of mortality in the high-salt consumption category was approximately 126 % higher than that of the reference category (non-consumers) [HR value 2⋅26, (95 % CI 0⋅91, 5⋅63)], while this risk for the low-to-moderate consumption group was about 28 % lower than the reference category [HR value 0⋅72, (95 % CI 0⋅26, 1⋅99), P-trend = 0⋅04]. In conclusion, a high daily dietary intake of salt might increase the rate of mortality and moderate salt restriction (instead of elimination of salt) decreases the risk of death.

ABSTRACT

AIM: The aim of this study was to determine the relation between different food groups intake, nutritional status of cirrhotic patient and the stage of the disease. BACKGROUND: Protein-energy malnutrition (PEM) is a common problem in cirrhotic patients. Food intake assessment is highly important in the investigation regarding the health-disease process. METHODS: In this cross-sectional study, sixty eight ambulatory cirrhotic patients, with a mean age of 54 years, were included. In order to assess the stage of the disease and malnutrition status, Child-Pugh score and Subjective Global Assessment index were used respectively. Dietary intakes were assessed using a 168-item semi-quantitative validated food frequency questionnaire. Odds ratios (OR) and the corresponding 95% confidence intervals (CI) were computed, using logistic regression models. RESULTS: After adjustment for confounders, we found significant inverse relations between intakes of nuts (OR=0.140, CI=0.031-0.625) and olive (OR=0.212, CI=0.049-0.917) with severity of disease and boiled potatoes (OR=0.154, CI=0.040-0.592) and legumes (OR=0.090, CI=0.020-0.406) with malnutrition status. Inversely, solid fats (OR=3.324, CI=1.080-10.238) and mayonnaise (OR=5.215, CI=1.203-22.612) were positively associated with disease severity and malnutrition, respectively. CONCLUSION: These findings suggest that selection of healthy foods was negatively associated with severity of hepatic cirrhosis whereas unhealthy food groups had a positive relation with disease severity and malnutrition.

ABSTRACT

AIM: To evaluate the association between dietary protein sources with disease severity, malnutrition and anthropometric measurements in cirrhotic patients. BACKGROUND: Although the beneficial effects of protein and some amino-acids have been shown previously, no study has evaluated the effects of different dietary sources of proteins in patients with hepatic cirrhosis. METHODS: In this cross-sectional study, dietary intakes of patients with hepatic cirrhosis were assessed using a valid and reliable food frequency questionnaire. The association between different dietary sources of proteins and nutritional status, anthropometric measurements, and disease severity were evaluated. RESULTS: Muscle strength (MS) increased significantly in highest tertile of dairy and vegetable protein sources compared with the lowest one (p=0.045). Dietary dairy and vegetable protein intakes had a positive significant correlation with body weight, MS, visceral fat percentage (VFP), and triceps skin-fold thickness (TST), and negative significant correlation with malnutrition stage. CONCLUSION: Our results indicate that consumption of proteins from dairy and vegetable sources is associated with improvement in nutritional and anthropometric status of patients with hepatic cirrhosis. Further prospective studies are needed to confirm these results.
