Since vitamin D deficiency is a well-known feature in AIH [39], and vitamin D is also known to exert potent immunomodulatory roles [40,41,42], we also assessed the association of serum vitamin D levels with the differentially expressed proteins in the AIH group identified in the Cardiometabolic panel (CA1, CA3, GAS6, FCGR2A, TIMD4, EFEMP1) and Inflammation panel (4E-BP1, CCL19, CSF-1, CX3CL1, CCL23, IL-18R1, IL-10RB, OPG, CXCL10). Here, IL10RB is linked to autoimmune hepatitis.
