A new risk score can identify first-degree relatives at higher risk for advanced nonalcoholic fatty liver disease (NAFLD) fibrosis. This tool aids in targeted screening for NAFLD in families with a history of advanced liver fibrosis.
Area of Science:
- Hepatology
- Genetics
- Public Health
Background:
- Nonalcoholic fatty liver disease (NAFLD)-related fibrosis has a heritable component.
- Identifying at-risk first-degree relatives for advanced fibrosis is crucial but challenging.
- Current methods for familial risk stratification in NAFLD are limited.
Purpose of the Study:
- To develop and validate a simple risk score for identifying first-degree relatives at higher risk of NAFLD with advanced fibrosis.
- To aid in early detection and intervention for familial NAFLD.
- To improve surveillance strategies for individuals with a family history of NAFLD.
Main Methods:
- A prospective, cross-sectional, familial study with derivation and validation cohorts in the US and Finland.
- Inclusion of adult probands with and without NAFLD and advanced fibrosis, and their first-degree relatives.
- Liver fibrosis assessment, primarily via magnetic resonance elastography, for all participants.
Main Results:
- The NAFLD Familial Risk Score was developed using age, type 2 diabetes, obesity, and proband's advanced fibrosis status.
- The score demonstrated high accuracy (AUC=0.94) in detecting advanced fibrosis in validation cohorts.
- The NAFLD Familial Risk Score significantly outperformed the Fibrosis-4 index (AUC=0.70).
Conclusions:
- The NAFLD Familial Risk Score is a simple, accurate tool for identifying advanced fibrosis in first-degree relatives.
- This score has significant implications for targeted surveillance in families affected by NAFLD.
- Early identification can lead to timely interventions and improved patient outcomes.
