Another recent study explored the enhanced liver fibrosis (ELF) score, a validated circulating biomarker of liver fibrosis derived from serum levels of hyaluronic acid (HA), tissue inhibitor of metalloproteinase 1 (TIMP-1), and pro-collagen III amino-terminal pro-peptide (PIIINP), in 24 patients with TAK. Here, TIMP1 is linked to Hepatic fibrosis.
