ARTICLE HIGHLIGHTS
Research background

Non-alcoholic fatty liver disease (NAFLD) is a spectrum of disease ranging from simple steatosis to non-alcoholic steatohepatitis (NASH), through to advanced fibrosis and cirrhosis. Many patients with NAFLD remain undiagnosed and recognizing those at risk is very crucial. Although liver biopsy is the gold standard method for diagnosing and staging NAFLD, non-invasive imaging and lab modalities are also very promising in diagnosing these diseases.

Research motivation

The main motivation for this research was to objectively assess existing non-invasive modalities alone or in combination and determine whether they could accurately help in diagnosing and staging liver disease, foregoing the need for invasive diagnostics such as liver biopsy.

Research objectives

The objective of this research was to combine clinical, lab, and imaging data and assess their ability to accurately diagnose and stage NAFLD without invasive diagnostics such as liver biopsy.

Research methods

This study was conducted on NAFLD/NASH patients (n = 73) who underwent Fibroscan examinations at Saint George Hospital University Medical Center over 17 mo in order to assess liver fibrosis. Obtained Fibroscan results were correlated to laboratory tests and calculated aspartate transaminase (AST)/alanine transaminase (ALT) ratio, AST platelet ratio index (APRI) score and Fibrosis-4 score.

Research results

A significant age difference was observed across fibrosis stages of investigated patients. The mean stiffness score was 9.48 ± 11.77 KPa. A significant positive correlation was found between Bilirubin, PT INR, partial thromboplastin time, glucose, and platelet count when compared across fibrosis stages, in addition to AST/ALT ratio, APRI, and Fib-4 scores.

Research conclusions

We conclude that ultrasound alone is not efficient in the assessment of the advancement of liver disease. Furthermore, the high positive relation between AST/ALT ratio, APRI and Fib-4 scores with fibrosis stages in NAFLD patients suggests that they could be used clinically in combination with Fibroscan to predict significant fibrosis and cirrhosis and to avoid liver biopsy.

Research perspectives

More research and data is required to make better recommendations. As more and more fields of clinical medicine forego invasive diagnostics in favor of their non-invasive counterparts, the data for such a shift in the diagnosis and staging of NAFLD is encouraging.
