(1) Introduction: Zonulin (ZO) has been proposed as a marker of intestinal permeability. Only a few studies have analyzed to date how diet influences the serum concentration of ZO among patients with non-alcoholic fatty liver disease (NAFLD). We performed a six-month dietetic intervention to evaluate the association between fiber intake and ZO concentration in 32 individuals with NAFLD. (2) Methods: Fiber content in the diet was estimated by Food Frequency Questionnaire (FFQ) and by analyzing 72-h nutritional diaries. ZO concentrations in serum were measured before and after the intervention by immunoenzymatic assay (ELISA). Fatty liver was quantified using the Hamaguchi score before and after the dietetic intervention. (3) Results: During the intervention, the dietary fiber intake increased from 19 g/day to the 29 g/day concomitant with an increase in the frequency of fiber consumption. All patients experienced significant (all p < 0.05) improvements in serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma-glutamyltransferase (GGTP) activities. We also detected decreased serum triglycerides (p = 0.036), homeostatic model assessment insulin resistance (HOMA-IR (p = 0.041) and insulin content (p = 0.34), and improvement of fatty liver status according to the Hamaguchi score (p = 0.009). ZO concentration in serum decreased by nearly 90% (7.335 ± 13.492 vs. 0.507 ± 0.762 ng/mL, p = 0.001) and correlated with the amount of dietary fiber intake (p = 0.043) as well as the degree of fatty liver (p = 0.037). (4) Conclusion: Increasing nutritional fiber results in reduced serum ZO levels, reduced liver enzymes and improved hepatic steatosis in patients with NAFLD, possibly by altering intestinal permeability. Increased dietary fiber intake should be recommended in patients with NAFLD.

Nonalcoholic fatty liver disease (NAFLD) includes a wide spectrum of liver diseases, ranging from pure steatosis to nonalcoholic steatohepatitis (NASH), and eventually to liver cirrhosis with its complications. Identifying advanced fibrosis in patients is crucial to evaluating prognosis and possible therapeutic intervention. A novel, simple, and highly accurate scoring system called BARD, which identifies patients with NAFLD and without significant fibrosis, has been recently introduced and validated in North America..The aim of this study is to validate the BARD scoring system in a Polish cohort with NAFLD.

Background and Aims: The European Reference Network on Hepatological Diseases (ERN RARE‐LIVER) launched the prospective, multicentre, quality‐controlled R‐LIVER registry on rare liver diseases. The aim of this study was to assess the presentation and outcome of autoimmune hepatitis (AIH) after 1 year of treatment.Methods: Data were prospectively collected at the time of diagnosis and after 6 and 12 months follow‐up. Complete biochemical response (CBR) was defined as normalization of alanine aminotransferase (ALT) and immunoglobulin G (IgG) serum levels.Results: A total of 231 patients from six European centres were included in the analysis. After 6 months of treatment 50% (106/212), and after 12 months 63% (131/210) of patients reached CBR with only 27% (56/211) achieving a steroid‐free CBR within the first year.Overall, 16 different treatment regimens were administered. Change of treatment, mostly due to intolerance, occurred in 30.4% within the first 6 months. In multivariate analysis, younger age at diagnosis (odds ratio [OR] = 1.03 [95% confidence interval (CI) 1.01–1.05]; p = .007), severe fibrosis (OR .38 [95% .16–.89], p = .026) and change of treatment within the first 6 months (OR .40 [95% CI .2–.86]; p = .018) were associated with a lesser chance of ALT normalization at 12 months follow‐up.Conclusion: The landscape of AIH treatment in Europe is highly heterogeneous, even between expert centres. The results from this first European multicentre prospective registry reveal several unmet needs, highlighted by the overall low rates of CBR and the frequent failure to withdraw corticosteroids.

Nutrients play a fundamental role as regulators of the activity of enzymes involved in liver metabolism. In the general population, the action of nutrients may be affected by gene polymorphisms. Therefore, individualization of a diet for individuals with fatty liver seems to be a fundamental step in nutritional strategies. In this study, we tested the nutrient-induced insulin output ratio (NIOR), which is used to identify the correlation between the variants of genes and insulin resistance. We enrolled 171 patients, Caucasian men (n = 104) and women (n = 67), diagnosed with non-alcoholic fatty liver disease (NAFLD). From the pool of genes sensitive to nutrient content, we selected genes characterized by a strong response to the NIOR. The polymorphisms included Adrenergic receptor (b3AR), Tumor necrosis factor (TNFα), Apolipoprotein C (Apo C III). Uncoupling Protein type I (UCP-1), Peroxisome proliferator activated receptor γ2 (PPAR-2) and Apolipoprotein E (APOEs). We performed three dietary interventions: a diet consistent with the results of genotyping (NIOR (+)); typical dietary recommendations for NAFLD (Cust (+)), and a diet opposite to the genotyping results (NIOR (−) and Cust (−)). We administered the diet for six months. The most beneficial changes were observed among fat-sensitive patients who were treated with the NIOR (+) diet. These changes included improvements in body mass and insulin sensitivity and normalization of blood lipids. In people sensitive to fat, the NIOR seems to be a useful tool for determining specific strategies for the treatment of NAFLD.

AIM: To describe a Polish population with nonalcoholic fatty liver disease (NAFLD) with regard to HFE gene mutations, as well as analyzing demographic and clinical data.

BACKGROUND In living donor liver transplantation (LDLT), 2 patients undergo surgery, and the advantages and disadvantages for both patients should be considered. This study evaluated the long-term quality of life in living liver donors, and its impact on their activities of daily living focusing on mood and mental health. MATERIAL AND METHODS In total, 101 living liver donors (69 female and 32 male patients, median age of 36.8 years) were surveyed at a median time of 61.8 months after liver donation (range 7-169 months). The generic Short Form Health Survey (SF-36), the Patient Health Questionnaire 9 (PHQ-9), and the Questionnaire of Physical Activity (IPAQ) were used. The results of SF-36 were compared to a matched control group (n=72) using the Wilcoxon test; the SF-36, the PHQ-9, and the IPAQ scores were analyzed using Spearman's rank correlation. Linear regression model was used to check for dependencies between variables of interest. The IPAQ results were compared between the study group and the general Polish population. RESULTS There were no significant differences in the SF-36 domains between the study group and control group except body pain, which was higher in the living liver donor group (P<0.05). In 30.6% of patients, the PHQ-9 survey revealed mood disturbances. The PHQ-9 scores were higher in female-donors (P<0.05). Both summary scores of the SF-36 correlated to the PHQ-9 (P<0.001). In 89.1% of patients, physical activity was below the population norm and was lower in female donors than in male donors (P<0.01). CONCLUSIONS LDLT had no impact on donors' physical and mental health. Physical activity of living liver donors was lower than that of the general population. The SF-36 and the IPAQ measures seem to be reliable in the care of living liver donors. The PHQ-9 survey results and the inclination to depression of female living liver donors requires further study.
