Abstract Background With the rates of non-alcoholic fatty liver disease (NAFLD) on the rise, the necessity of identifying patients at risk of cirrhosis and its complications is becoming ever more important. Liver biopsy remains the gold standard for assessing fibrosis, although the costs, risks, and availability prohibit its widespread use for at-risk patients. Fibroscan has proven to be a non-invasive and accurate way of assessing fibrosis, although the availability of this modality is often limited in the primary care setting. The Fibrosis-4 (FIB-4) and Non-Alcoholic Fatty Liver Disease Fibrosis Score (NFS) are scoring systems which incorporate commonly measured lab parameters and BMI to predict fibrosis. In this study, we compared FIB-4 and NFS values to fibroscan scores to assess the accuracy of these inexpensive and readily available scoring systems for detecting fibrosis. Aims The aim of this study was to determine if non-invasive and inexpensive scoring systems (FIB-4 and NFS) can be used to rule out fibrosis in non-alcoholic fatty liver disease with comparable efficacy to fibroscan. Ultimately, we aim to demonstrate that these scoring systems can be used as an alternative to fibroscan in some patients. Methods Data was collected from 317 patient charts from the Vancouver General Hepatology Clinic. 93 patients were removed from the study due to insufficient data (missing Fibroscan score or lab work necessary for FIB-4/NFS). For the remaining 224 patients, FIB-4 and NFS were calculated and compared to fibrosis scores both independently and in combination. Results: Using a NFS score cut-off of -1.455 and a fibroscan score cut-off of ≥8.7kPa, the NFS had a sensitivity of 71.9%, a specificity of 75%, and a negative predictive value of 94.1%. For a fibroscan score cut-off of ≥8.0kPa, the NFS had a sensitivity of 66.7%, a specificity of 75.7%, and a negative predictive value of 91.5%. Using a fibroscan score cut-off of ≥8.7kPa, the FIB-4 score had a sensitivity of 53.1%, specificity of 84.9%, and a negative predictive value of 91.6%. For a cut-off of ≥8.0kPa, it had a sensitivity of 51.3%, and 85.9%, and a negative predictive value of 89.3%. Conclusions: The NFS and FIB-4 are non-invasive scoring systems that have high sensitivity and negative predictive value for fibrosis when compared to fibroscan scores. These findings suggest that the NFS and FIB-4 can provide adequate reassurance to rule-out fibrosis in select patients, and has promising use in the primary care setting where fibroscan access is often limited.

These findings suggest that the NFS and FIB-4 can provide adequate reassurance to rule out fibrosis in patients with NAFLD and can be used with select patients to circumvent the need for transient elastography or liver biopsy.

Alcoholic Fatty Liver Disease

Non-alcoholic fatty liver disease (NAFLD) has become the most common liver alteration worldwide. It encompasses a spectrum of disorders that range from simple steatosis to a progressive form, defined non-alcoholic steatohepatitis (NASH), that can lead to advanced fibrosis and eventually cirrhosis and hepatocellular carcinoma. On liver histology, NASH is characterized by the concomitant presence of significant fat accumulation and inflammatory reaction with hepatocellular injury. Until now, liver biopsy is still required to differentiate simple steatosis from NASH and evaluate the degree of liver fibrosis. Unfortunately, this technique has well-known limitations, including invasiveness and expensiveness. Moreover, it may be biased by sampling error and intra- or inter-observed variability. Furthermore, due to the increasing prevalence of NAFLD worldwide, to program a systematic screening with liver biopsy is not imaginable. In recent years, different techniques were developed and validated with the aim of non-invasively identifying NASH and assess liver fibrosis degrees. The non-invasive tests range from simple blood-tests analyses to composite scores and complex imaging techniques. Nevertheless, even if they could represent cost-effective strategies for diagnosing NASH, advanced fibrosis and cirrhosis, their accuracy and consequent usefulness are to be discussed. With this aim, in this review the authors summarize the current state of non-invasive assessment of NAFLD. In particular, in addition to the well-established tests, the authors describe the future perspectives in this field, reporting the latest tests based on OMICS, gut-miocrobioma and micro-RNAs. Finally, the authors provide an accurate assessment of how these non-invasive tools perform in clinical practice depending on the clinical context, with the aim of giving the clinicians a useful tool to try to resolve the diagnostic conundrum of NAFLD.

Alcoholic Fatty Liver Disease

The prevalence and severity of non-alcoholic fatty liver disease (NAFLD) is increasing, yet adequately validated tests for care paths are limited and non-invasive markers of disease progression are urgently needed. The aim of this work was to summarize the performance of Pro-C3, a biomarker of active fibrogenesis, in detecting significant fibrosis (F ≥ 2), advanced fibrosis (F ≥ 3), cirrhosis (F4) and non-alcoholic steatohepatitis (NASH) in patients with NAFLD. A sensitive search of five databases was performed in July 2021. Studies reporting Pro-C3 measurements and liver histology in adults with NAFLD without co-existing liver diseases were eligible. Meta-analysis was conducted by applying a bivariate random effects model to produce summary estimates of Pro-C3 accuracy. From 35 evaluated reports, eight studies met our inclusion criteria; 1568 patients were included in our meta-analysis of significant fibrosis and 2058 in that of advanced fibrosis. The area under the summary curve was 0.81 (95% CI 0.77–0.84) in detecting significant fibrosis and 0.79 (95% CI 0.73–0.82) for advanced fibrosis. Our results support Pro-C3 as an important candidate biomarker for non-invasive assessment of liver fibrosis in NAFLD. Further direct comparisons with currently recommended non-invasive tests will demonstrate whether Pro-C3 panels can outperform these tests, and improve care paths for patients with NAFLD.
