We have evaluated flu vaccine coverage and variables associated with the lack of vaccination in cirrhotic subjects with particular attention to the cirrhosis etiology. Cirrhotic subjects consecutively referring to eight Italian centers were prospectively enrolled for a 6‐month period in 2019. Subjects were asked if they had received a flu vaccine in the last 12 months. Multiple logistic regression analysis was performed to identify independent predictors of lack of vaccination. A total of 818 cases were recruited. The overall vaccine coverage was 39.6% (26.9% in those younger than 65 years and 51.9% in those older than 64 years; p < 0.001). Age < 65 years (odds ratio [OR] = 2.38; 95% confidence interval [CI] = 1.68–3.36), alcoholic etiology (OR = 2.40; 95% CI = 1.49–3.85), birth abroad (OR = 2.7; 95% CI = 1.10–6.61), and residence in South/Sardinia island (OR = 1.66; 95% CI = 1.14–2.42) all resulted independent predictors of the likelihood of lack of vaccination. The lack of information regarding the vaccine as the reason for no vaccination was reported by 71.4% of foreigners and by 34.7% of natives (p < 0.001). In conclusion, much work still should be done to improve coverage among groups at higher risk of lack of vaccination identified in this survey. The ongoing SARS‐CoV‐2 pandemic may represent one more alert for improving seasonal flu vaccine coverage to avoid further stress to the National Health System. Highlights: Flu vaccine coverage is often perceived less beneficial in patients withliver disease resulting lower among cirrhotic subjects.Flu infection may cause collateral liver damage such as an usually mild and self‐limiting hepatitis and trigger hepatic decompensation in liver disease.Age (<65 years), birth abroad and alcoholic etiology resulted to be independent predictors of the likelihood of lack of flu vaccination in cirrhotic subjects.

Increased concentrations of serum aspartate transaminase (AST) and alanine transaminase (ALT) are common in COVID‐19 patients. However, their capacity to predict mortality, particularly the AST/ALT ratio, commonly referred to as the De Ritis ratio, is unknown. We investigated the association between the De Ritis ratio on admission and in‐hospital mortality in 105 consecutive patients with coronavirus disease of 2019 (COVID‐19) admitted to three COVID‐19 referral centres in Sardinia, Italy. The De Ritis ratio was significantly lower in survivors than nonsurvivors (median: 1.25; IQR: 0.91‐1.64 vs 1.67; IQR: 1.38‐1.97, P =.002) whilst there were no significant between‐group differences in ALT and AST concentrations. In ROC curve analysis, the AUC value of the De Ritis ratio was 0.701 (95% CI 0.603‐0.787, P =.0006) with sensitivity and specificity of 74% and 70%, respectively. Kaplan‐Meier survival curves showed a significant association between the De Ritis ratio and mortality (logrank test P =.014). By contrast, no associations were observed between the ALT and AST concentrations and mortality (logrank test P =.83 and P =.62, respectively). In multivariate Cox regression analysis, the HR in patients with De Ritis ratios ≥1.63 (upper tertile of this parameter) remained significant after adjusting for age, gender, smoking status, cardiovascular disease, intensity of care, diabetes, respiratory diseases, malignancies and kidney disease (HR: 2.46, 95% CI 1.05‐5.73, P =.037). Therefore, the De Ritis ratio on admission was significantly associated with in‐hospital mortality in COVID‐19 patients. Larger studies are required to confirm the capacity of this parameter to independently predict mortality in this group. [ABSTRACT FROM AUTHOR]
