RESUMO
BACKGROUND AND AIMS: Metabolic dysfunction (MD)-associated fatty liver disease has been proposed to identify individuals at risk of liver events irrespectively of the contemporary presence of other liver diseases. The aim of this study was to examine the impact of MD in patients cured of chronic hepatis C (CHC). PATIENTS AND METHODS: We analysed data from a real-life cohort of 2611 Italian patients cured of CHC with direct antiviral agents and advanced liver fibrosis, without HBV/HIV, transplantation and negative for hepatocellular carcinoma (HCC) history (age 61.4 ± 11.8 years, 63.9% males, median follow-up 34, 24-40 months). Information about ultrasonographic steatosis (US) after sustained virological response was available in 1978. RESULTS: MD affected 58% of patients, diagnosed due to the presence of diabetes (MD-diabetes, 19%), overweight without diabetes (MD-overweight, 37%) or multiple metabolic abnormalities without overweight and diabetes (MD-metabolic, 2%). MD was more frequent than and not coincident with US (32% MD-only, 23% MD-US and 13% US-only). MD was associated with higher liver stiffness (p < 0.05), particularly in patients with MD-diabetes and MD-only subgroups, comprising older individuals with more advanced metabolic and liver disease (p < 0.05). At Cox proportional hazard multivariable analysis, MD was associated with increased risk of HCC (HR 1.97, 95% CI 1.27-3.04; p = 0.0023). Further classification according to diagnostic criteria improved risk stratification (p < 0.0001), with the highest risk observed in patients with MD-diabetes. Patients with MD-only appeared at highest risk since the sustained virological response achievement (p = 0.008), with a later catch-up of those with combined MD-US, whereas US-only was not associated with HCC. CONCLUSIONS: MD is more prevalent than US in patients cured of CHC with advanced fibrosis and identifies more accurately individuals at risk of developing HCC.

The aim of this study was to examine the impact of features of dysmetabolism on liver disease severity, evolution, and clinical outcomes in a real-life cohort of patients treated with direct acting antivirals for chronic hepatitis C virus (HCV) infection. To this end, we considered 7,007 patients treated between 2014 and 2018, 65.3% with advanced fibrosis, of whom 97.7% achieved viral eradication (NAVIGATORE-Lombardia registry). In a subset (n = 748), liver stiffness measurement (LSM) was available at baseline and follow-up. Higher body mass index (BMI; odds ratio [OR] 1.06 per kg/m2 , 1.03-1.09) and diabetes (OR 2.01 [1.65-2.46]) were independently associated with advanced fibrosis at baseline, whereas statin use was protective (OR 0.46 [0.35-0.60]; P < 0.0001 for all). The impact of BMI was greater in those without diabetes (P = 0.003). Diabetes was independently associated with less pronounced LSM improvement after viral eradication (P = 0.001) and in patients with advanced fibrosis was an independent predictor of the most frequent clinical events, namely de novo hepatocellular carcinoma (HCC; hazard ratio [HR] 2.09 [1.20-3.63]; P = 0.009) and cardiovascular events (HR 2.73 [1.16-6.43]; P = 0.021). Metformin showed a protective association against HCC (HR 0.32 [0.11-0.96]; P = 0.043), which was confirmed after adjustment for propensity score (P = 0.038). Diabetes diagnosis further refined HCC prediction in patients with compensated advanced chronic liver disease at high baseline risk (P = 0.024). Conclusion: Metabolic comorbidities were associated with advanced liver fibrosis at baseline, whereas statins were protective. In patients with advanced fibrosis, diabetes increased the risk of de novo HCC and of cardiovascular events. Optimization of metabolic comorbidities treatment by a multi-disciplinary management approach may improve cardiovascular and possibly liver-related outcomes.

BACKGROUND AND AIMS: The efficacy and safety of glecaprevir/pibrentasvir (G/P) for patients infected with hepatitis C virus (HCV) have only been investigated in clinical trials, with no real-world data currently available. The aim of our study was to investigate the effectiveness and safety of G/P in a real-world setting. METHODS: All patients with HCV consecutively starting G/P between October 2017 and January 2018 within the NAVIGATORE-Lombardia Network were analyzed. G/P was administered according to drug label (8, 12 or 16â¯weeks). Fibrosis was staged either histologically or by liver stiffness measurement. Sustained virological response (SVR) was defined as undetectable HCV-RNA 12â¯weeks after the end of treatment. RESULTS: A total of 723 patients (50% males) were treated with G/P, 89% for 8â¯weeks. The median age of our cohort was 58â¯years, with a median body mass index of 23.9â¯kg/m2, and median liver stiffness measurement of 6.1â¯kPa; 84% were F0-2 and 16% were interferon-experienced. Median HCV-RNA was 1,102,600â¯IU/ml, and 49% of patients had HCV genotype 1 (32% 1b), 28% genotype 2, 10% genotype 3 and 13% genotype 4. The median estimated glomerular filtration rate was 90.2â¯ml/min, platelet count 209x103/mm3 and albumin 4.3â¯g/dl. The SVR rates were 94% in intention-to-treat and 99.3% in per protocol analysis (8-week vs. 12 or 16-week: 99.2% vs. 100%). Five patients failed therapy because of post-treatment relapse; a post-treatment NS5A resistance-associated substitution was detected in 1 case. SVR rates were lower in males (p = 0.002) and in HCV genotype-3 (p = 0.046) patients treated for 8â¯weeks, but independent of treatment duration, fibrosis stage, baseline HCV-RNA, HIV co-infection, chronic kidney disease stage and viral kinetics. Mild adverse events were reported in 8.3% of the patients, and 0.7% of them prematurely withdrew treatment. Three patients died of drug-unrelated causes. CONCLUSIONS: In a large real-world cohort of Italian patients, we confirmed the excellent effectiveness and safety of G/P administered for 8, 12 or 16â¯weeks. LAY SUMMARY: A large number of patients with hepatitis C virus have been treated with glecaprevir/pibrentasvir (G/P) within the NAVIGATORE-Lombardia Network, in Italy. This is the first real-world study evaluating effectiveness and safety of G/P in patients with hepatitis C virus treated according to international recommendations. This study demonstrated excellent effectiveness (with sustained virological response rates of 99.3%) and safety profiles.

BACKGROUND & AIMS: Transaminasemia develops via different pathways in patients with celiac disease; no information is available on risk factors specifically attributable to celiac disease. METHODS: We analyzed data collected from consecutive patients referred from January 1997 through December 2009 to the celiac disease clinic at the Spedali Civili of Brescia, Italy. We assessed the factors affecting hypertransaminasemia in 683 patients with celiac disease (based on serologic and biopsy analysis, cohort A; 34 ± 14 years of age) and 304 with functional syndromes (cohort B; 37 ± 13 years of age). RESULTS: Hypertransaminasemia was detected in 138 patients in cohort A (20%). It was associated with malabsorption (odds ratio [OR], 2.22; P = .004), diarrhea (OR, 1.72; P = .005), and increasing severity of mucosal lesion (Marsh-Oberhuber class; OR, 1.46; P = .001) but not with body mass index (BMI) or the serum level of tissue-transglutaminase antibodies (tTG). Hypertransaminasemia was detected in 22 patients in cohort B (7%) and was associated with the World Health Organization's BMI categories (OR, 7.9; P < .001). In subsets of patients studied with the same analytical method (313 of cohort A and 188 of cohort B), the level of tTG was significantly higher in cohort A at baseline (25.2 ± 16.9 U/L aspartate aminotransferase [AST]) than in cohort B (20.6 ± 9.9 U/L AST, P < .0001) and was related to BMI in cohort B (P = .0012) but not cohort A. When patients were placed on gluten-free diets, the levels of AST decreased from 25.2 ± 16.9 U/L to 19.9 ± 6.6 U/L (P < .0001), independently of the changes of duodenal histology and tTG and correlated with BMI (P = .0007); the prevalence of hypertransaminasemia decreased from 13% to 4%. CONCLUSIONS: Patients with celiac disease have a higher prevalence of hypertransaminasemia than controls (patients with functional syndromes). Hypertransaminasemia is related to the severity of the duodenal lesion and malabsorption but not BMI. By contrast, there was a positive correlation between the levels of AST and BMI in controls; this relationship was restored when patients with celiac disease were placed on gluten-free diets.

BACKGROUND AND AIM: Increased pretreatment gamma-glutamyl-transpeptidase (gammaGT) is common in patients with chronic hepatitis C and with little or no alcohol consumption. The mechanism involved in this phenomenon is unclear, and the aim of this study was to investigate factors associated with increased gammaGT levels, specifically looking at the role of cholestasis that frequently accompanies hepatitis C. METHODS: Fifty patients with chronic hepatitis C enrolled in two trials of antiviral treatment, 25 with normal and 25 with elevated pretreatment gammaGT levels, were retrospectively selected. In addition to the common liver function and virological tests, other values measured were serum bile acid concentration and composition by gas-chromatography as a sensitive index of cholestasis, and liver biopsy scores for cholestasis and steatosis in addition to siderosis, fibrosis and inflammation. RESULTS: Total mean serum bile acid concentration was 11.6 +/- 1.4 micromol/L and 8.5 +/- 1.2 micromol/L (not significant) in patients with elevated and with normal gammaGT, respectively, and individual bile acid composition was similar in the two groups. By univariate analysis, serum gammaGT level was linearly related to total serum bile acid (P < 0.05) and to cholestasis score (P < 0.001) among other variables, but steatosis score (P < 0.001) and Knodell score (P < 0.04) were the only variables independently associated with elevated serum gammaGT level by multivariate analysis. CONCLUSIONS: Increased serum gammaGT level in patients with chronic hepatitis C is associated with liver steatosis and fibrosis, and indicates more advanced liver disease rather than reflecting the cholestasis that often accompanies this condition.
