FIB-4 score as predictor of COVID-19-related severity in hospitalized patients.

AIM: To determine the impact of liver fibrosis on the prognosis of COVID and the liver injury associated with the infection. METHODS: Retrospective multicenter study including 575 patients requiring admission for COVID-19 between January and June 2020. FIB-4 was calculated within 6 months prior to infection and at 6 months post-infection. RESULTS: Baseline FIB-4 was increased in patients who died (1.91±0.95 vs. 1.43±0.85; p<0.001). In addition, the 17.1% (32/187) of patients with baseline FIB-4<1.45 died versus 52.9% (9/17) if FIB-4>3.25 (p<0.001). In the adjusted multivariate analysis, baseline FIB-4 (OR 1.61 (95%CI 1.19-2.18); p=0.002) was independently associated with mortality. Parameters associated with liver injury, including AST (28±10 vs. 45±56IU/L; p<0.001) and ALT (20±12 vs. 38±48IU/L; p<0.001) were significantly higher at admission compared to baseline. Also, FIB-4 was increased from baseline to the time of admission (1.53±0.88 vs. 2.55±1.91; p<0.001), and up to 6.9% (10/145) of patients with FIB-4<1.45 at admission died versus 47.5% if FIB-4>3.25 (58/122) (p<0.001). In the adjusted multivariate analysis, FIB-4 at admission (OR 1.14 (95%CI 1.03-1.27); p=0.015) was independently associated with mortality. Also, AST (42±38 vs. 22±17IU/L; p<0.001) and ALT (40±50 vs. 20±19 IU/L; p<0.001) were significantly reduced at 6 months after the resolution of infection. Accordingly, FIB-4 decreased significantly (2.12±1.25 vs. 1.32±0.57; p<0.001) six months after the infection. CONCLUSION: Increased FIB-4, either at baseline or at the time of admission, was related to the severity and mortality related to SARS-CoV-2 infection. However, the liver damage expressed by elevated transaminases and FIB-4 was reversible in most of patients.

Three double-dose reinforced hepatitis B revaccination scheme for patients with cirrhosis unresponsive to the standard regimen: an open-label randomised clinical trial.

OBJECTIVE: We aimed to compare the response rates between two different hepatitis B virus vaccination schedules for cirrhotic subjects who were non-responders to the first three 40 µg doses (month 0-1-2), and identify factors associated with the final response. DESIGN: A total of 120 cirrhotic patients (72.5% decompensated) were randomised at a 1:1 ratio to receive a single 40 µg booster vaccination at month 6 (classical arm) versus an additional round of three new 40 µg doses administered at monthly intervals (experimental arm). The main outcome was the rate of postvaccinal anti-hepatitis B surface antibodies levels ≥10 mIU/mL. RESULTS: Efficacy by ITT analysis was higher in the experimental arm (46.7%) than in the classical one (25%); OR 2.63, p=0.013. The experimental arm increased response rates compared with the classical one from 31% to 68% (OR 4.72; p=0.007), from 24.4% to 50% (OR 3.09; p=0.012) and from 24.4% to 53.8% (OR 3.62; p=0.007), in Child A, Model for End-Stage Liver Disease (MELD) <15 and MELD-Na<15 patients, respectively. Patients with more advanced liver disease did not benefit from the reinforced scheme. Both regimens showed similar safety profiles. Multivariable analysis showed that the experimental treatment was independently response associated when adjusted across three logistic regression models indicating equivalent cirrhosis severity. CONCLUSION: For cirrhotic patients, the revaccination of non-responders to the first three dose cycle, with three additional 40 µg doses, achieved significantly better response rates to those obtained with an isolated 40 µg booster dose. TRIAL REGISTRATION NUMBER: NCT01884415.

Liver stiffness accuracy by magnetic resonance elastography in histologically proven non-alcoholic fatty liver disease patients: a Spanish cohort.

OBJECTIVES: to evaluate the performance of magnetic resonance elastography (MRE) to stage liver fibrosis in patients with histologically confirmed nonalcoholic fatty liver disease (NAFLD) and to assess the impact of potential confounding factors in MRE diagnostic accuracy. The secondary objective was to compare MRE with other non-invasive methods for staging fibrosis such as transient elastography (TE) and non-invasive scores (APRI and FIB-4). METHODS: sixty-five histologically confirmed NAFLD patients were prospectively enrolled at the Hospital Universitario Virgen del Rocío (Seville, Spain). Liver stiffness was measured by MRE, TE and non-invasive scores (APRI and FIB-4). Fibrosis was assessed by liver biopsy using the steatosis, activity and fibrosis (SAF) score. Patients were classified into three groups according to the consistency between MRE and histopathological findings: underestimation, concordance and overestimation groups. Areas under the ROC curve (AUROC) and diagnostic performance were evaluated. RESULTS: the area under the ROC curve (AUROC) of MRE in advanced fibrosis (≥ F3) was 0.90 (0.82-0.97), while TE AUROC was 0.82 (0.72-0.93) (p = 0.22) and lower for the non-invasive test (FIB-4 0.67 and APRI 0.62). Inflammatory activity, steatosis grade and higher levels of liver biochemistry appeared to overestimate MRE results in the univariate analysis, but only gamma-glutamyl transferase (GGT) was statistically significant in the multivariate analysis (p < 0.01). Age, sex, body mass index (BMI), weight, diabetes mellitus (DM), high blood pressure (HBP), platelets or lipidic profile did not affect MRE accuracy. CONCLUSIONS: MRE is an effective and non-invasive method for detecting and staging liver fibrosis in NAFLD patients. MRE is more accurate than TE and allows the study of liver anatomy. Histological inflammation and surrogate biomarkers of inflammation can overestimate liver stiffness, but only GGT was statistically significant in the multivariate analysis. Important features of NAFLD patients such as obesity, DM, or lipidic profile did not affect MRE accuracy.

Prevalence of non-alcoholic fatty liver disease (NAFLD) in a cohort of patients with type 2 diabetes: the PHIGNA-DM2 study.

Introduction: Background: type 2 diabetes (T2D) is a risk factor for nonalcoholic fatty liver disease (NAFLD). Objective: to evaluate the prevalence of NAFLD in a cohort of patients with T2D. Methods: an observational, descriptive study performed between May 2018 and December 2019 at the Endocrinology and Nutrition Unit. The χ² test was performed for qualitative variables and a non-parametric test for the comparison of medians of quantitative variables. Steatosis degree was defined by the coefficient attenuated parameter (CAP): (S0: < 248 dB/m; S1: 248-268 dB/m; S2: 268-288 dB/m; S3: > 288 dB/m) or stiffness: F0-F1: < 8 kPa; F2: 8-10 kPa; F3: 10-15 kPa; F4: > 15 kPa, using transient elastography (TE) (FibroScan®). A univariate analysis was performed and subsequently a multivariate analysis with statistically significant variables used to study the predictive factors of intense steatosis and advanced fibrosis. Results: n = 104 patients with T2D; 84 (80.7 %) were obese. TE demonstrated advanced fibrosis in 20 % and intense steatosis (S3) in more than 50 %. Lower total bilirubin (OR: 0.028; 95 % CI: (0.002-0.337); p = 0.005) was found to be an independent factor for S3 steatosis in the multivariate analysis. BMI ((OR: 1.497; 95 % CI: (1.102-2.034); p = 0.01)) was a predictive factor for advanced fibrosis in a multivariate analysis. Conclusions: NAFLD-associated intense steatosis and NAFLD-associated fibrosis were commonly found in patients with T2DM and obesity. Diabetic patients should be screened for liver disease as one more target organ.

Introducción: Antecedentes: la diabetes de tipo 2 (DM2) es un factor de riesgo para la enfermedad del hígado graso no alcohólico (EHGNA). Objetivo: evaluar la prevalencia de la EHGNA en una cohorte de pacientes con DM2. Métodos: estudio descriptivo observacional realizado entre mayo de 2018 y diciembre de 2019 en la Unidad de Endocrinología y Nutrición. Se realizó una prueba de χ² para las variables cualitativas y una prueba no paramétrica para la comparación de medianas de variables cuantitativas. El grado de esteatosis se definió mediante el parámetro coeficiente atenuado (CAP): (S0: < 248 dB/m; S1: 248-288 dB/m; S2: 268-288 dB/m; S3: > 288 dB/m) o rigidez: F0-F1: < 8 kPa; F2: 8-10 kPa; F3: 10-15 kPa; F4: > 15 kPa, usando la elastografía transitoria (TE) (FibroScan®). Se realizó un análisis univariante y posteriormente un análisis multivariante con las variables estadísticamente significativas para estudiar los factores predictivos de esteatosis intensa y fibrosis avanzada. Resultados: n = 104 pacientes con DM2; 84 (80,7 %) eran obesos. La TE demostró fibrosis avanzada en el 20 % y esteatosis intensa (S3) en más del 50 %. Los niveles disminuidos de bilirrubina total (OR: 0.028; 95 % CI: (0.002-0.337); p = 0.005) se encontraron como factores independientes para la esteatosis S3 en el analisis multivariable. El IMC (OR: 1.497; 95 % CI: (1.102-2.034); p = 0.01) fue un factor predictivo de fibrosis avanzada. Conclusiones: la esteatosis intensa asociada a EHGNA y la fibrosis asociada a EHGNA se encontraron comúnmente en pacientes con DM2 y obesidad. Los pacientes diabéticos deben someterse a pruebas de detección de enfermedad hepática como un órgano diana más.
