Abstract Background The aim of this study was to propose a simple predictive score to differentiate NASH from simple steatosis. Results This study included 64 patients who had biopsy-proven NAFLD, of which 34 patients had steatohepatitis and 30 had simple steatosis. Clinical, anthropometric, and biochemical variables of the study population were analyzed. Univariate analysis showed platelet count, ferritin, and transaminases (ALT&AST) were predictors of NASH. This led to the proposal of a new diagnostic tool, FAT score (F signifies Ferritin, A indicates AST&ALT, T denotes t in Platelet) with AUROC of 0.95. The ROC curves for the significant variables were plotted and cutoff values were identified. Each component is awarded a score of 0 or 1, based on this cutoff value. The component is awarded a score of 1 if the component score is above the cutoff value and 0, if the score is below cutoff. The maximum score which can be obtained is 4. A score of ≥ 3 was able to predict NASH from simple steatosis with a sensitivity of 76.5% and a specificity of 100%. The score was validated with a cohort of 84 liver biopsy patients wherein a cutoff ≥ 3 was found to give a specificity of 100% in the validation cohort. Conclusions FAT score is a simple predictive model to differentiate NASH from simple steatosis (cutoff of more than or equal to 3) without performing a liver biopsy. A FAT score less than 3 rules out the need for biopsy.

Abstract Objectives The aim of the study was to compare food patterns in patients with simple steatosis (SS) and non-alcoholic steatohepatitis (NASH). Methods Prospective study was approved by LEC and enrolled subjects with confirmed non-alcoholic fatty liver disease (SS or NASH group). Nutrilogic software (Nutrilogic, Russia) was used for diet assessment. Dietary patterns were assessed according to the Healthy Eating Index (HEI): amounts of the major groups of foods and food products (grains, fruits, vegetables, dairy products, meats, fats and confectioneries) consumption were compared to the levels described in the HEI, and individual deviation rates were obtained. Nonparametric statistics (Mann-Whitney U test) was used to compare deviation rates found in subjects of SS and NASH groups. Results Subjects in NASH group (n = 22) were younger (Mean ± SD: 48.6 ± 13.4 y.o.) than those in SS group (n = 156; 56.5 ± 12.3 y.o., P = 0.008). Main macronutrients consumption did not differ between the groups. Although dietary patterns of major groups of foods consumption did not differ between SS and NASH groups, analysis of the foods subgroups revealed dissimilarity in the structure of vegetables and fats consumption. Patients with NASH consumed larger amounts of potatoes (0.14 ± 0.08 vs 0.11 ± 0.15, P = 0.006), and lower – of onions (0.02 ± 0.03 vs 0.07 ± 0.1, P = 0.006); they also consumed lower amounts of dairy butter (0.14 ± 0.44 vs 0.15 ± 0.21, P = 0.009) compared to subjects with simple steatosis. No other difference in the structure of vegetables (beans, root crops, leafy and other vegetables), fats (animal fats, vegetable oils, margarines) and other major groups of foods consumption was revealed. Conclusions Dietary patterns of patients with non-alcoholic steatohepatitis and simple steatosis differ. The obtained results may help in diet modification in patients with NAFLD in case of confirmation in larger multicenter trials. Funding Sources Russian Science Foundation, grant #1976-30014.

Effectively assessing subtle hepatic metabolic functions by novel non-invasive tests might be of clinical utility in scoring NAFLD (non-alcoholic fatty liver disease) and in identifying altered metabolic pathways. The present study was conducted on 39 (20 lean and 19 obese) hypertransaminasemic patients with histologically proven NAFLD {ranging from simple steatosis to severe steatohepatitis [NASH (non-alcoholic steatohepatitis)] and fibrosis} and 28 (20 lean and eight overweight) healthy controls, who underwent stable isotope breath testing ([13C]methacetin and [13C]ketoisocaproate) for microsomal and mitochondrial liver function in relation to histology, serum hyaluronate, as a marker of liver fibrosis, and body size. Compared with healthy subjects and patients with simple steatosis, NASH patients had enhanced methacetin demethylation (P=0.001), but decreased (P=0.001) and delayed (P=0.006) ketoisocaproate decarboxylation, which was inversely related (P=0.001) to the degree of histological fibrosis (r=−0.701), serum hyaluronate (r=−0.644) and body size (r=−0.485). Ketoisocaproate decarboxylation was impaired further in obese patients with NASH, but not in patients with simple steatosis and in overweight controls. NASH and insulin resistance were independently associated with an abnormal ketoisocaproate breath test (P=0.001). The cut-off value of 9.6% cumulative expired 13CO2 for ketoisocaproate at 60 min was associated with the highest prediction (positive predictive value, 0.90; negative predictive value, 0.73) for NASH, yielding an overall sensitivity of 68% and specificity of 94%. In conclusion, both microsomal and mitochondrial functions are disturbed in NASH. Therefore stable isotope breath tests may usefully contribute to a better and non-invasive characterization of patients with NAFLD.
