The analysis in patients with AIH (n = 16) also showed that females are characterized by decreased hepatic hepcidin mRNA expression [0.3 (0.44) versus 1.56 (0.87); P = 0.004] and, in the same group, serum hepcidin levels associated positively with INR (P = 0.003). Here, HAMP is linked to autoimmune hepatitis.
