Correlations Between Viro-Immunologic Status of the Newly Diagnosed Patient with HIV Infection and Liver Damage

Abstract Liver damage can be a direct consequence of human immunodeficiency virus infection or indirect mechanisms triggered by human immunodeficiency virus. Hepatic fibrosis may be present in patients newly diagnosed with HIV infection or in those with viro-immunologic failure after initiation of antiretroviral therapy. In the present study we evaluated biologically and viro-immunologically the 351 patients newly diagnosed with HIV infection in the Regional Center Constanta between 01.01.2015 and 31.06.2024, subsequently re- evaluated one year after diagnosis and institution of specific medication. Liver fibrosis stage was assessed using APRI, FIB4 and FORNS scores. The cohort comprised 351 patients, 313 with HIV monoinfection. The mean age at diagnosis was 36.09 years, predominantly male (237 patients). The median CD4+ cell count was 269.5 cells/mm3, and the median HIV-RNA was 164 x103 copies/mL. Most cases were CDC staged A2 (91 cases) and C3 (77 cases). Patients with HIV monoinfection showed a significant association between CD4+ cell level and ALT (p=0.026) and AST (p<0.001), respectively. We observed statistically significant correlation between AST and viral load values (p=0.003 in monoinfection and 0.042 in coinfection). APRI, FIB4 and FORNS scores averaged higher in the coinfected group compared to the HIV monoinfected group. Statistically significant associations were found between APRI, FIB4, FORNS scores and CD4+ cell counts and HIV viral load values, respectively.

Benchmarking clinical risk prediction algorithms with ensemble machine learning for the noninvasive diagnosis of liver fibrosis in NAFLD.

Ensemble machine-learning methods, like the superlearner, combine multiple models into a single one to enhance predictive accuracy. Here we explore the potential of the superlearner as a benchmarking tool for clinical risk prediction, illustrating the approach to identifying significant liver fibrosis among patients with NAFLD. We used 23 demographic/clinical variables to train superlearner(s) on data from the NASH-clinical research network observational study (n = 648) and validated models with data from the FLINT trial (n = 270) and National Health and Nutrition Examination Survey (NHANES) participants with NAFLD (n = 1244). Comparing the superlearner's performance to existing models (Fibrosis-4 [FIB-4], NAFLD fibrosis score, Forns, AST to Platelet Ratio Index [APRI], BARD, and Steatosis-Associated Fibrosis Estimator [SAFE]), it exhibited strong discriminative ability in the FLINT and NHANES validation sets, with AUCs of 0.79 (95% CI: 0.73-0.84) and 0.74 (95% CI: 0.68-0.79) respectively. Notably, the SAFE score performed similarly to the superlearner, both of which outperformed FIB-4, APRI, Forns, and BARD scores in the validation data sets. Surprisingly, the superlearner derived from 12 base models matched the performance of one with 90 base models. Overall, the superlearner, being the "best-in-class" machine-learning predictor, excelled in detecting fibrotic NASH, and this approach can be used to benchmark the performance of conventional clinical risk prediction models.

Liver Fibrosis Scores as Predictors of Long-term Outcomes in Patients with ST-segment Elevation Myocardial Infarction

Background: Liver fibrosis scores (LFSs) are novel tools for predicting cardiovascular events in patients with coronary artery disease. This study was aimed at examining the prognostic value of LFSs in patients with ST-segment elevation myocardial infarction (STEMI). Methods: Between 2015 and 2019, 866 patients diagnosed with STEMI were consecutively enrolled. The definition of major cardiovascular events (MACEs) was all-cause death, nonfatal myocardial infarction, nonfatal ischemic stroke, and acute limb ischemia. We evaluated the predictive values of LFSs for MACEs with receiver operating characteristic (ROC) curve and restricted cubic spline (RCS) analysis. Kaplan-Meier (K-M) analysis was conducted to explore the relationship between LFSs and MACEs. Results: During a median follow-up of 4 years, 155 MACEs were observed. K-M analysis of MACEs revealed significantly lower event-free survival rates in patients with intermediate or high, rather than low, NFS, FIB-4, BARD, and Forns scores. The multivariable-adjusted hazard ratios (95% CI) for MACEs in patients with high versus low risk scores were 1.343 (0.822–2.197) for NFS, 1.922 (1.085–3.405) for FIB-4, 2.395 (1.115–5.142) for BARD, and 2.271 (1.250–4.125) for Forns. The ROC curve indicated that the predictive ability for MACEs was non significantly improved by addition of the NFS (AUC = 0.7274), FIB-4 (AUC = 0.7199), BARD (AUC = 0.7235), and Forns (AUC = 0.7376) scores into the basic model (AUC = 0.7181). RCS revealed a tendency toward a nonlinear positive association of MACEs with NFS, FIB-4, and particularly Forns scores. Conclusion: LFSs have potential utility for predicting adverse outcomes in patients with STEMI, thus indicating the importance of managing metabolic dysregulation.

Evaluation of liver fibrosis by non-invasive markers (transient elastography vs. APRI, FIB-4, and FORNS) in chronic hepatitis C virus carriers in a low-income country

Abstract Background: The interest in evaluating hepatic fibrosis stems from the fact that the risk of developing cirrhosis following hepatitis C virus (HCV) infection is estimated at 10%–20%. The aim of this study was to identify feasible, accessible, and affordable non-invasive methods other than transient elastography (TE) in the evaluation of liver fibrosis in a resource-limited country. Materials and Methods: This was a cross-sectional analytical study conducted over 24 months in two health facilities in Douala, Cameroon. All chronically infected HCV patients who had undergone a TE were enrolled. In this study, TE was considered the gold standard for evaluating hepatic fibrosis. Other non-invasive markers considered were the aspartate transaminase to platelet ratio (APRI) index, fibrosis-4 (FIB-4), and FORNS scores. The sensitivity (Se), specificity (Sp), positive predictive value, and negative predictive value of each marker to determine significant fibrosis and cirrhosis were calculated for different thresholds, and the best Se/Sp ratio evaluated by the area under the receiving operating characteristic curve. Results: One hundred eighty-four patients were enrolled. The mean age was 56.2 ± 10.6 years with a female predominance. There was a positive correlation between TE and the FIB-4 score, the APRI score, and the FORNS score. The threshold values to predict significant fibrosis for the FIB-4, APRI, and FORNS score were 2, 0.5, and 7.6, respectively. The threshold values to predict cirrhosis for the FIB-4, APRI, and FORNS scores were 3.2, 1.3, and 9.6, respectively. Conclusion: The FIB-4 score is the best at predicting significant fibrosis, while the APRI and FIB-4 scores are the best at predicting cirrhosis in hepatitis C patients when compared to TE as the gold standard.

A surveillance for advanced liver disease and characterization of hyperechogenic lesions after Fontan surgery in a prospective cohort of cases with congenital univentricular heart

Abstract Background The congenital univentricular heart (UH) is a rare disease corrected with the palliative Fontan’s intervention, that restores the survival of most child and young patients up to adultwood. Unlikely, these patients develop a series of complications, among all, the Fontan associated liver disease (FALD), that causes the occurrence of liver cirrhosis and hepatocellular carcinoma (HCC), that negatively impacts the life expectancy in the majority of cases. Purpose Our primary aim was to identify the presence of severe FALD in our patients by liver fibrosis and portal hypertension scores (FORNS, liver and spleen-platelet score or LSPS and SSPS), and by liver (LS) and spleen (SS) stiffness measurement in relation to time since Fontan, and secondarly to characterize all the abdominal-US hyperechogenic lesions (US-HL) according to the LI-RADS (LR) CT/MRI categories. Method One-hundred-46 outpatients (83 m/63 f, aged 25,2±11.0 yrs) born with UH corrected with Fontan circuit have been recruited prospectively from 2019 to 2023 (FUmean 24.5±15.1 mos). Each patient underwent a complete clinical history and instrumental examination, by imaging obtained with US, CT and MRI, a specific lab-test profile, and the LS and SS evaluation by transient elastography (VCTE, Fibroscan). ROC curves were built to select the scores cut-off proved to be the most accurate to diagnose and grade FALD. Based on the presence of US-HL found in 43 cases (29,5%), we grouped: 23 cases with LR-1 or 2 (benign), 15 with LR-3 (suspect) and 5 with LR-4 or 5 (malign). Results Features for definition of failing-Fontan appeared in 17.5%, 47.5% and 80% of cases with <15; 15-25 or >25yrs since Fontan surgery, respectively (p<0.01). All the scores used (FORNS with cut-off ≥4, LSPS ≥1.4, SSPS ≥2.3, LS ≥20.2 and SS ≥30.7) showed high sensitivity and specificity, improving FALD diagnostic accuracy and staging (all p<0.001). Moreover by identification of selective criteria related to advanced liver disease and portal hypertension, we applied a novel risk-score for failing-Fontan, that predicted a low-moderate risk profile (HR 0.30;CI 0.18-0.52) in 72 patients and a high risk profile (HR 3,29,CI 1.93-5.60) in 74 (51%). During FU, 13 patients (8.9%) died, 5 received OHT (3.4%) and 5 had HCC occurrence (3.4%). Finally, cases with US-HL stratified by classes LR-3-4-5 (20 cases, 46.5%) appeared significantly associated with a more advanced FALD (16/4, 75% vs. 68/58, 46%; p=0,004) and a longer time since Fontan (26.3±9.4 vs. 19.8±10.8; p=0,025). Conclusion The novel risk score proposed may help to predict the development of cirrhosis in high risk patients and focussed on the need for surveillance by imaging methods to characterized the US-HL, that appeared at risk of malignity (nodule size >20mm and/or presence of wash-out into portal-hepatocellular phase or into LR ≥3 classes).

Association between liver fibrosis and thrombotic or bleeding events in acute coronary syndrome patients

BackgroundThe prognostic implication of liver fibrosis in acute coronary syndrome (ACS) patients are scarce. We sought to evaluate whether liver fibrosis scores (LFS) were associated with thrombotic or bleeding events in patients with acute coronary syndrome.MethodsWe included 6386 ACS patients who underwent percutaneous coronary intervention (PCI). This study determined liver fibrosis with aspartate aminotransferase to platelet ratio index (APRI), aspartate aminotransferase to alanine aminotransferase ratio (AST/ALT ratio), Forns score, and nonalcoholic fatty liver disease fibrosis score (NFS). The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), a composite of all-cause mortality (ACM), myocardial infarction (MI), and ischemic stroke (IS).ResultsDuring the follow-up, 259 (4.06%) MACCE and 190 (2.98%) bleeding events were recorded. As a continuous variable or a categorical variable stratified by the literature-based cutoff, LFS was positively associated with MACCE (p > 0.05) but not with bleeding events. Compared with subjects with low APRI scores, AST/ALT ratio scores, Forns scores, and NFS scores, subjects with high scores had a 1.57- to 3.73-fold increase risk of MACCE after adjustment (all p < 0.05). The positive relationship between LFS and MACCE was consistent in different subgroups.ConclusionsIn ACS patients, increased LFS predicted an elevated risk of thrombotic events but not bleeding. LFS may contribute to thrombotic risk stratification after ACS.

Liver Health in Patients with Hemophilia: Residual Risk Factors of Liver-Related Complications after HCV Clearance

Background and Aim: Hepatitis C virus (HCV) is highly prevalent in patients with hemophilia, but today almost all patients achieve a sustained virological response (SVR) to therapy. Unfortunately, other risk factors (e.g. metabolic and/or alcohol) can make chronic hepatitis continue even after SVR and, potentially, evolve to cirrhosis. We herein report data from a prospective hepatological screening program aimed at evaluating any relevant risk factor of liver-related complications after SVR in patients with hemophilia. Methods: We enrolled 75 HCV-patients (median age: 54; range: 36-80): 68/7 hemophilia A/B, 63% suffering from a severe inherited bleeding disorder. At time of inclusion, 22 patients (29%) had achieved a SVR after successful interferon-based therapies, 48 (64%) after third generation antiviral agents, 5 (7%) had obtained a spontaneous virus clearance. All patients were screened for active etiologic factors of chronic hepatitis, biochemistry, liver stiffness measurement (LSM) and ultrasound-exploration (US) to rule in/out cirrhosis. Invasive diagnostic tests were adopted when appropriate. Data before SVR were available in 44 patients for pre/post-SVR analysis to explore their potential diagnostic accuracy to rule out an advanced chronic liver disease at time of the screening. Results: Thirty-one patients (41%) presented at least one active risk factor of potential chronic liver damage, metabolic syndrome being the most prevalent (36%). Twenty-nine patients (39%) had also HIV/HBV infection although adequately treated at time of the screening. Steatosis was detected by US in 37 patients (48%). Based on clinical, biochemical and/or morphological criteria 21 patients (28%) had signs cirrhosis. Among them, 4 patients (5%) had esophageal varices needing treatment, 3 (4%) hepatocellular carcinoma (HCC). One HCC was detected in a non-cirrhotic liver but was associated with metabolic comorbidities, 2 were HCC out of transplantation criteria and were addressed to a multi-disciplinary down-staging approach (e.g. surgery, chemoembolization, chemotherapy). Finally 2 of HCC were transplanted. All the non-invasive tests for cirrhosis (e.g. LSM, APRI, Fib4, Forns score) were sensibly reduced after virus clearance (p<0.05). On the contrary typical US-signs of cirrhosis did not significantly change after SVR. Eleven patients had LSM between 6-9 KPa. Interestingly, 3 of them had irregular liver surface, 1 caudate hypertrophic liver lobe, 6 splenomegaly, suggesting that non-invasive tests may not accurately rule out an advanced chronic liver disease after HCV clearance even for low levels of LSM. Conclusions: A residual risk of chronic liver damage after HCV-clearance is frequently observed. Non-invasive tests of fibrosis dramatically change after SVR and could be inaccurate to rule out cirrhosis. A specific diagnostic work-up is mandatory to preserve liver-health in this clinical setting.

Association between Coronary Artery Plaque Progression and Liver Fibrosis Biomarkers in Population with Low Calcium Scores.

Background: The severity of nonalcoholic fatty liver disease (NAFLD) has been found to be associated with atherosclerosis burden. However, whether liver fibrosis scores can be used to predict atherosclerosis progression, especially for patients with low calcium scores, remains undetermined. Methods: A total of 165 subjects who underwent repeated coronary computed tomography angiography (CCTA) and had low calcium scores (<100) were enrolled. The segment stenosis score (SSS) from the CCTA was measured, and the association between SSS progression and biochemical parameters was analyzed in addition to liver fibrosis scores, including nonalcoholic fatty liver disease fibrosis score (NFS), fibrosis-4 index (FIB-4), aspartate aminotransferase (AST) to platelet ratio index (APRI), and Forns score. Results: When compared with those without plaque at baseline (SSS = 0), subjects with plaque had higher blood pressure, higher coronary artery calcium (CAC) scores, and higher liver fibrosis scores, including Forns score, Fib-4, and NFS. During the medium follow-up interval of 24.7 months, 60 (39.4%) patients displayed SSS progression, while the remaining 105 (63.6%) patients showed no CAD progression. In a multivariate analysis, being male having a high diastolic blood pressure (DBP), and having a high NFS liver fibrosis score were independently associated with the odds ratio for SSS progression. Conclusions: Higher baseline blood pressure and liver fibrosis markers are associated with the presence of coronary artery disease (CAD) plaques in subjects in early CAD stages. For disease progression, the male gender, DBP, and NFS appear to be independently associated with coronary atherosclerosis plaque progression in subjects with low calcium scores.

Non-invasive Liver Fibrosis Scores Are Associated With Recurrence of Postoperative Chronic Subdural Hematoma.

ObjectiveAlthough liver diseases have already been identified as a risk factor for increased recurrence and mortality in patients with chronic subdural hematoma (CSDH), the association between subclinical liver disease, specifically liver fibrosis (LF), and CSDH remains unknown. In the present study, we aimed to investigate the association between the LF scores and CSDH recurrence.MethodsWe retrospectively analyzed consecutive patients with CSDH who underwent burr-hole irrigation in the First Affiliated Hospital of Wenzhou Medical University between January 2015 and December 2018. The clinical data were collected, and the LF scores were calculated including aspartate aminotransferase–platelet ratio index (APRI), fibrosis-4 (FIB-4), and Forns index. Multivariable logistic regression analysis was applied to identify the association between the LF scores and CSDH recurrence, and Cox regression model and Fine–Gray competing risks model were performed to calculate hazard ratios (HRs) for CSDH recurrence based on time-to-event outcomes. The C-statistic, the integrated discrimination improvement (IDI), and the net reclassification improvement (NRI) evaluated the additive value of the LF scores to predict the recurrence of CSDH.ResultsA total of 419 patients with CSDH were included, hematoma recurrence was observed in 62 patients (14.80%) within 1 year after surgery. The LF scores were significantly higher in those who recurred, whereas the standard hepatic assays were mostly normal. The patients were assigned to groups of high and low LF scores based on the validated cut-offs; compared with the subjects with low scores, those with high score levels had significantly higher recurrence rates. After adjusting for potential confounders, the LF scores were independently associated with CSDH recurrence, multivariable-adjusted HRs (95% CI) for those with higher levels of APRI, FIB-4, and Forns score were 4.32 (1.37–13.60), 2.56 (1.20–5.43), and 2.02 (1.07–3.79) for the recurrence of CSDH, respectively. Moreover, adding the APRI to the conventional model improved the C-statistic from 0.731 to 0.763, with an NRI and IDI of 7.50 and 1.35%, respectively. Two further commonly-used LF score indices (FIB-4 score and Forns index) yielded comparable results.ConclusionsThe data from this study first indicated that the high LF scores were significantly associated with the recurrence of CSDH and that careful follow-up in these patients may be needed.

Non-Invasive Liver Fibrosis Scores Are Associated With Contrast-Associated Acute Kidney Injury in Patients Undergoing Elective Percutaneous Coronary Intervention.

Previous studies have demonstrated that non-invasive liver fibrosis scores (LFSs) are associated with kidney function deterioration. This study aimed to assess the predictive performance of LFSs in contrast-associated acute kidney injury (CA-AKI) in coronary artery disease (CAD) patients undergoing elective percutaneous coronary intervention (PCI). This retrospective study involved 5627 patients. The frequency of CA-AKI was 6.3% (n = 353). In a multivariate logistic analysis after adjustment, non-invasive LFSs, including fibrosis-5 score (FIB-5), fibrosis-4 score (FIB-4), aspartate aminotransferase to alanine aminotransferase ratio (AAR), and aspartate aminotransferase to platelet ratio index were independent risk factors for CA-AKI (all P < .05), whereas the Forns score was not (P > .05). The highest predictive performance was observed for FIB-5 (area under the curve [AUC] = .644) compared to other LFSs. A restricted cubic spline analysis confirmed approximately linear relationships between LFSs and risks of CA-AKI. Furthermore, adding FIB-5 (AUC = .747; net reclassification improvement [NRI] = .441, P < .001; integrated discrimination improvement [IDI] = .008, P < .001) or AAR (AUC = .747; NRI = .419, P < .001; IDI = .006, P = .010) to an established clinical risk model could significantly improve the prediction of CA-AKI. The LFSs were significantly associated with CA-AKI, possibly serving as predictive tools for early identification of CAD patients undergoing elective PCI that are at high risk of CA-AKI.

Acoustic radiation force impulse elastography and liver fibrosis risk scores in severe obesity.

Identifying significant fibrosis is crucial to evaluate the prognosis and therapeutic interventions in patients with nonalcoholic fatty liver disease (NAFLD). We assessed the performance of acoustic radiation force impulse (ARFI) elastography, APRI, FIB-4, Forns, NFS and BARD scores in determining liver fibrosis in severe obesity. A prospective study included 108 patients undergoing bariatric surgery. Liver biopsy specimens were obtained intraoperatively and classified according to the NAFLD Activity Score. Patients were assessed with serological markers and shear wave velocity of the liver was measured with the Siemens S2000 ultrasound system preoperatively. Optimal cut-off values were determined using the area under the receiver operating characteristic curves (AUROC). In the entire cohort prevalence of NAFLD was 80.6%, steatohepatitis 25.9% and significant fibrosis 19.4%. The best tests for predicting significant fibrosis were FIB-4 and Forns scores (both AUROC 0.78), followed by APRI (AUROC 0.74), NFS (AUROC 0.68), BARD (AUROC 0.64) and ARFI (AUROC 0.62). ARFI elastography was successful in 73% of the patients. Higher body mass index (BMI) correlated with invalid ARFI measurements. In patients with BMI < 42 kg/m2, ARFI showed 92.3% sensitivity and 82,6% specificity for the presence of significant fibrosis, with AUROC 0.86 and cut-off 1.32 m/s. FIB-4 and Forns scores were the most accurate for the prediction of significant fibrosis in bariatric patients. Applicability and accuracy of ARFI was limited in individuals with severe obesity. In patients with BMI < 42 kg/m2, ARFI elastography was capable for predicting significant fibrosis with relevant accuracy.

Liver Fibrosis Scoring Systems as Novel Tools for Predicting Recurrent Cardiovascular Events in Patients with a Prior Cardiovascular Event

Abstract Objective: Regarding the secondary prevention of cardiovascular disease (CVD), there is great interest in preventing recurrent cardiovascular events (RCVEs). The prognostic importance of liver fibrosis scores (LFSs) has previously been reported in various CVDs. We hypothesized that LFSs might also be useful predictors for RCVEs in patients with prior cardiovascular events (CVEs). Herein, we aimed to evaluate the associations of LFSs with RCVEs in a large, real-world cohort of coronary artery disease (CAD) patients with a prior CVE. Methods: In this multicenter prospective study, 6527 consecutive patients with angiography-diagnosed CAD who had experienced a prior CVE (acute coronary syndrome, stroke, percutaneous coronary intervention, or coronary artery bypass grafting) were enrolled. LFSs were computed according to the published formulas: non-alcoholic fatty liver disease fibrosis score (NFS) includes age, body mass index (BMI), impaired fasting glycemia or diabetes mellitus (DM), aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio, platelets, and albumin; fibrosis-4 (FIB-4) includes age, AST, ALT, and platelets; Forns score includes age, gamma-glutamyltransferase (GGT), and platelets; BARD includes BMI, AST/ALT ratio, and DM; GGT/platelet ratio includes GGT and platelets; AST/ALT ratio includes AST and ALT; and AST/platelet ratio index includes AST and platelets. The originally reported cutoffs were used for the categorization of low-, intermediate-, and high-score subgroups. All patients were followed up for the occurrence of RCVEs (comprising cardiovascular death, non-fatal myocardial infarction, and stroke). Cox and Poisson regression analyses were used to assess the relationship of baseline LFSs with the risk of RCVE. Results: During a mean follow-up of (54.67 ± 18.80) months, 532 (8.2%) RCVEs were recorded. Intermediate and high NFS, FIB-4, Forns, and BARD scores were independently associated with an increased risk of RCVE (hazard ratios ranging from 1.42 to 1.75 for intermediate scores and 1.35 to 2.52 for high scores). In the subgroup analyses of sex, age, BMI, DM, and hypertension status, the increased risk of RCVEs with high LFSs (NFS, FIB-4, Forns, and BARD) was maintained across the different subgroups (all P &lt; 0.05). Conclusion: This study showed that LFSs are indeed independently associated with RCVEs, suggesting that LFSs may be used as novel tools for risk stratification in CAD patients with a prior CVE.

A Polygenic Risk Score to Refine Risk Stratification and Prediction for Severe Liver Disease by Clinical Fibrosis Scores

A polygenic risk score based on well-known genetic variants in PNPLA3, TM6SF2, MBOAT7, and GCKR predicts hepatic fat content (polygenic risk score-hepatic fat content [PRS-HFC]). Here, we hypothesized that the addition of PRS-HFC to clinical fibrosis scores may improve risk stratification and prediction of severe liver disease (SLD). We used data from 266,687 individuals in the UK Biobank, evaluating the incidence of cirrhosis, decompensated liver disease, hepatocellular carcinoma, and/or liver transplantation during a median follow-up period of 9 years. Nonalcoholic fatty liver disease fibrosis score, Fibrosis-4, aspartate aminotransferase-to-platelet ratio, BARD, and Forns scores, and PRS-HFC, were computed. All analyses were stratified according to the presence of diabetes, obesity, and a positive fatty liver index (≥60). Unfavorable genetics (PRS-HFC, ≥0.396) further stratified the risk of SLD in subjects in intermediate-/high-risk classes of fibrosis scores, with a higher effect in those with metabolic risk factors, and the prediction was improved by integrating PRS-HFC (areas under the receiver operating characteristic increased for all scores with a P value of approximately 10-2 to 10-4, except for the aspartate aminotransferase-to-platelet ratio in the overall population and in subjects with obesity). PRS-HFC improved diagnostic accuracies and positive predictive values for SLD in intermediate-high clinical score risk classes. Risk stratification and prediction were not affected or were poorly affected by unfavorable genetics in subjects without metabolic risk factors. Integration of genetics with clinical fibrosis scores refines individual risk and prediction for SLD, mainly in individuals at risk for nonalcoholic fatty liver disease. These data provide evidence from a prospective cohort that common genetic variants capture additional prognostic insights not conveyed by validated clinical/biochemical parameters.

Diagnostic Accuracy of the Forns Score for Liver Cirrhosis in Patients With Chronic Viral Hepatitis.

IntroductionLiver cirrhosis is an irreversible and end-stage disease. It results from chronic liver damage characterized by the replacement of normal liver tissue by fibrosis, leading to the progressive loss of liver function. Making an early diagnosis of cirrhosis is important for patients with chronic hepatitis because early antiviral therapy can prevent the progression of cirrhosis and even induce regression. There have been efforts to develop surrogate markers for liver cirrhosis as the biopsy is invasive, costly, and difficult to standardize.MethodsThis was a cross-sectional study conducted at the Section of Chemical Pathology, the Department of Pathology and Laboratory Medicine in Collaboration with the Section of Gastroenterology, Department of Medicine, the Aga Khan University, from January to December 2018. A total of 90 patients (>18 years of age) with a history of chronic viral hepatitis, who were attending the FibroScan® (Echosens, Paris, France) clinic were included. Patients with a history of autoimmune liver diseases and hepatocellular carcinoma were excluded from the study. Blood samples withdrawn were analyzed on ADVIA Centaur® (Siemens Healthineers, Erlangen, Germany), and Forns scores were calculated based on the following four parameters: patient age, total cholesterol, gamma-glutamyl transferase (GGT), and platelet count.ResultsThe median age of the patients was 38.5 years [interquartile range (IQR): 21]. Among the study population, 59 (65.6%) were males and 31 (34.4%) were females; 26 patients showed reactivity for hepatitis B surface antigen (HBsAg), and 63 patients were found chronic with hepatitis C virus (HCV). The proportion of HCV was observed to be higher as compared with that of Hepatitis B virus (HBV). Nineteen patients were found to have jaundice and only one patient had ascites. An Area Under the Receiver Operating Curve (AUROC) was generated to determine the diagnostic accuracy of the Forns score. It was observed that the Forn score value of >7.110 had an AUROC of 0.9928 (95% CI: 0.9821-1.003, p-value: <0.001) with a sensitivity of 100% (95% CI: 91.19-100.0%) and specificity of 94% (95% CI: 83.45-98.75%), with a higher positive likelihood ratio of 16.67.ConclusionThis study found the Forns score to be sensitive and specific in diagnosing liver cirrhosis in patients with chronic hepatitis. The Forns score at a cutoff of 7.11 is highly sensitive as well as a specific noninvasive method that can be used to ascertain the status of fibrosis in chronic hepatitis patients.

The Diagnosis Value of a Novel Model with 5 Circulating miRNAs for Liver Fibrosis in Patients with Chronic Hepatitis B.

Methods Differential expression of five selected miRNAs (hsa-mir-1225-3p, hsa-mir-1238, hsa-miR-3162-3P, hsa-miR-4721, and hsa-miR-H7) was verified by qRT-PCR in the plasma of 83 patients and 20 healthy controls. The relative expression of these miRNAs was analyzed in different groups to screen target miRNA. A logistic regression analysis was performed to assess factors associated with fibrosis progression. The receiver operating characteristic (ROC) curve and discriminant analyses validated the ability of these predicted variables to discriminate the nonsignificant liver fibrosis group from the significant liver fibrosis group. Furthermore, the established models were compared with other prediction models to evaluate the diagnostic efficiency. Results These five tested miRNAs all had signature correlations with hepatic fibrotic level (p < 0.05), and the upregulation trends were consistent with miRNA microarray analysis previously. The multivariate logistic regression analysis identified that a model of five miRNAs (miR-5) had a high diagnostic accuracy in discrimination of different stages of liver fibrosis. The ROC showed that the miR-5 has excellent value in diagnosis of fibrosis, even better than the Forns score, FIB-4, S index, and APRI. GO functions of different miRNAs mainly involved in various biological processes were markedly involved in HBV and revealed signaling pathways dysregulated in liver fibrosis of CHB patients. Conclusions It was validated that the combination of these five miRNAs was a new set of promising molecular diagnostic markers for liver fibrosis. The diagnosis model (miR-5) can distinguish significant and nonsignificant liver fibrosis with high sensitivity and specificity.

Impact of liver fibrosis score on prognosis in patients with previous myocardial infarction: A prospective cohort study.

Liver fibrosis score (LFS) has been used for predicting the cardiovascular outcomes (CVOs) in diverse populations. However, the association of LFS with CVOs in patients with previous myocardial infarction (MI) remains undetermined. We aimed to examine the prognostic value of LFS in patients with prior MI in a prospective cohort. A total of 3718 patients with previous MI were consecutively enrolled from March 2009 to January 2019. Five LFSs including the fibrosis-4 (FIB-4) score, non-alcohol fatty liver disease fibrosis score (NFS), Forns score, HUI score and BARD score were used. The CVOs covered major adverse cardiac event (MACEs), cardiovascular mortality and all-cause mortality. Cox proportional hazards model was used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs). During a mean follow-up of 47.4±24.8months, 431 (11.6%) MACEs occurred. Kaplan-Meier analysis demonstrated that higher LFSs resulted in a significantly higher probability of CVOs. Compared to the lowest score group, multivariable-adjusted HRs (95% CIs) of the highest group of FIB-4, NFS, Forns score, HUI score and BARD score were 1.75 (1.32-2.33), 2.37 (1.70-3.33), 2.44 (1.61-3.73), 1.58 (1.16-2.14) and 1.27 (1.03-1.57) respectively. These LFSs were also independent predictors of cardiovascular mortality and all-cause mortality. Similar results were observed across subgroups analysis. The addition of LFSs to a prediction model significantly increased the C-statistic for CVOs. The present study firstly demonstrated that LFS could be used as a risk stratification tool for predicting CVOs in patients with previous MI, which should be evaluated further.

Abstract 15135: Liver Fibrosis Scores Predict Cardiovascular Outcomes in Patients With Previous Myocardial Infarction

Introduction: Liver fibrosis score (LFS) has been used for predicting the cardiovascular outcomes (CVOs) in diverse populations. However, the association of LFS with CVOs in patients with previous myocardial infarction (MI) remains undetermined. Hypothesis: The aim of the present study was to examine the prognostic value of LFS in patients with prior MI in a prospective cohort. Methods: A total of 3718 patients with previous MI were consecutively enrolled from March 2009 to January 2019. Five LFSs were used including the fibrosis-4 (FIB-4) score, non-alcohol fatty liver disease fibrosis score (NFS), Forns score, HUI score and BARD score in the current study. The CVOs covered major adverse cardiac event (MACE), hard endpoint, cardiovascular mortality and all-cause mortality. Cox proportional hazards model was used to calculate hazard ratios (HR) with 95% confidence intervals (CI). Results: During a mean follow-up of 47.4±24.8 months, 431 (11.6%) MACE occurred. Kaplan-Meier analysis demonstrated that higher LFSs resulted in a significantly higher probability of CVOs. Compared to the lowest score group, multivariable-adjusted HRs (95% CI) for the highest group of FIB-4, NFS, Forns score, HUI score and BARD score were 1.76 (1.33-2.34), 2.39 (1.71-3.34), 2.46 (1.62-3.74), 1.60 (1.18-2.17) and 1.28 (1.03-1.58), respectively. These LFSs were also independent predictors of hard endpoint, cardiovascular mortality and all-cause mortality. Similar results were observed across subgroups analysis. The addition of LFSs to a prediction model significantly increased the C-statistic for CVOs. Conclusions: The present study firstly demonstrated that LF scores might affect the prognosis in patients with previous MI, suggesting that LF scores may be helpful to further risk stratification and supporting LF scores screening in patients with previous MI.

Preoperative noninvasive assessment for liver fibrosis in hepatocellular carcinoma patients with chronic hepatitis B: Comparison of two-dimensional shear-wave elastography with serum liver fibrosis models

PurposeTo investigate the diagnostic performance of two-dimensional shear-wave elastography (2D-SWE) in hepatocellular carcinoma patients with chronic hepatitis B adapted to hepatectomy comparing to serum liver fibrosis models. Method100 patients with chronic hepatitis B who first diagnosed with hepatocellular carcinoma and had undergone 2D-SWE measurements before the hepatectomy were included. The performance of 2D-SWE and serum models in the diagnosis of liver fibrosis was assessed using receiver operating characteristic (ROC) analyses. ResultsThe areas under ROC (AUCs) for 2D-SWE, Forns score, aspartate transaminase-to-platelet ratio index (APRI) and Fibrosis 4 Score (FIB-4) were 0.983, 0.757, 0.745, 0.710 in the diagnosis of significant fibrosis (F ≥ 2) respectively, and 0.896, 0.718, 0.626, 0.575 in the diagnosis of cirrhosis (F = 4) respectively. The AUCs for 2D-SWE in the diagnosis of significant fibrosis and cirrhosis were significantly higher than those for the serum fibrosis models (p < 0.05). The AUCs of Forns in the diagnosis of significant fibrosis (F ≥ 2) showed no statistical differences (p > 0.05) with those of APRI and FIB-4 while in the diagnosis of cirrhosis (F = 4), they are significantly higher (p < 0.05). Conclusions2D-SWE is a reliable method for preoperative noninvasive assessment of liver fibrosis in HCC patients with CHB, with notably higher diagnostic accuracy than serum liver fibrosis models.
