| Summary: | Abstract Background and aims The ideal non-invasive marker to identify patient at risk for liver fibrosis in the general population is unknown. Current guidelines (EASL) recommend using the FIB-4 score as a screening tool but the low specificity may result in a large number of potentially false-positive results. Recently, the liver risk score (LRS) has been suggested to more accurately identify patients at-risk. The aim of our study was to identify populations at-risk using the two scores. Materials and methods “Cerbafib” was a prospective cohort derived from laboratories throughout the Paris region. The prevalence of advanced liver fibrosis was assessed using the non-invasive FIB-4 score with a cut-off of 2.67 (rule-in) and 1.3 (rule-out) and the LRS with a cut-off of < 6 (minimal risk), ≥ 6 to < 10 (low risk), ≥ 10 to < 15 (medium risk) and ≥ 15 (high risk). Results Between January and April 2023, 179 865 patients were included in the cohort. The mean age was 52 years and 45% were men. FIB-4 identified 55 376 (31%) patients requiring specialist referral ( ≥ = 1.3) and 4002 patients (2.2%) with suspected advanced fibrosis. LRS identified 38 175 (21%) patients with estimated liver stiffness ≥ 6 kPa, 1 933 patients (1%) ≥ 10 kPa and 35 (0.02%) patients ≥ 15 kPa. There was a poor correlation between the two tests (r = 0.45). Conclusion The Liver Risk Score is a practical tool to identify a population in need of further hepatologic evaluation. Compared to FIB-4, the population identified by LRS is smaller and different. An adapted new pragmatic screening algorithm using LRS should be considered. |
