| More Details: | Background: Platelet Derived Growth Factor Receptor beta (PDGFRβ) has been associated to hepatic stellate cell activation and has been the target of multiple therapeutic studies. However, little is known concerning its use as a diagnostic agent. Methods: Circulating PDGFRβ levels were analysed in a cohort of patients with liver fibrosis/cirrhosis due to chronic alcohol abuse, viral hepatitis, or non-alcoholic fatty liver disease (NAFLD). The diagnostic performance of PDGFRβ as individual blood parameter, or in combination with other metabolic factors was evaluated. Findings: sPDGFRβ levels are progressively increased with increasing fibrosis stage and the largest difference was observed in patients with significant fibrosis, compared to no or mild fibrosis. The accuracy of sPDGFRβ-levels predicting fibrosis could be increased by combining it with albumin levels and platelet counts into a novel diagnostic algorithm, the PRTA-score, generating a predictive value superior to Fib-4, APRI, and AST/ALT. The sPDGFRβ levels and the PRTA-score are independent of liver disease aetiology, thus overcoming one of the major weaknesses of current non-invasive clinical and experimental scores. Finally, we confirmed the diagnostic value of sPDGFRβ levels and the PRTA-score in an independent patient cohort with NAFLD which was staged for fibrosis by liver biopsy. Interpretation: The PRTA-score is an accurate tool for detecting significant liver fibrosis in a broad range of liver disease aetiologies.
