Abstract: Background and Aims: Type IV collagen 7S (COL4-7S) is a simple, noninvasive biomarker for liver fibrosis. However, whether COL4-7S can detect advanced fibrosis (AF) and predict the prognosis of metabolic dysfunction-associated steatotic liver disease (MASLD) is unclear. We examined the clinical efficacy of COL4-7S in diagnosing AF and determining MASLD prognosis. Methods: Overall, 881 Japanese patients with biopsy-proven nonalcoholic fatty liver disease between 1994 and 2020 were enrolled. Serum COL4-7S levels were measured by radioimmunoassay, and 2 cutoff points were set as 5.1 ng/mL and 7.2 ng/mL. The patients were assigned to 3 groups based on the COL4-7S level. Cox regression analysis was used to estimate the predictive performance of COL4-7S for liver-related events (LREs). Results: = .286). The incidence rate of LREs was low when the Fibrosis-4 Index (FIB-4) <1.30. When the FIB-4 >1.30, effective stratification of the LRE risk group was possible by stratification of COL4-7S. A combination of FIB-4 and COL4-7S stratified risk groups for future LRE development more effectively than when used singly. Conclusion: COL4-7S accurately diagnosed AF and predicted LREs. COL4-7S and a combination of FIB-4 and COL4-7S might help physicians estimate the prognosis of future LRE risk.
