Objective To investigate the correlation between serum protein level of insulin growth factor 1 (IGF‐1) and the degree of liver fibrosis in patients with chronic hepatitis C (CHC) combined with type 2 diabetes mellitus (T2DM). Methods The cases are divided into four groups. Then serum levels of IFG‐1, alanine aminotransferase (ALT), aspartate aminotransferase (AST), hepatitis C virus (HCV) RNA, and HCV genotypes were detected simultaneously in patients with hepatitis C, liver stiffness measurement (LSM) was measured by transient elastography, and aspartate aminotransferase platelet ratio (APRI) score was determined. Results There was no significant difference between CHC with T2DM group and CHC group in diabetes family history (P > 0.05), but the difference between the two groups were significantly lower than that of T2DM group ( P < 0.05). The levels of fasting insulin and homeostatic model assessment of insulin resistance (HOMA‐IR) in CHC group with T2DM group were significantly higher than those in the other two groups ( P < 0.05), while the IGF‐1 RNA and the serum protein level in the two groups were significantly lower than those in the CHC group, and were lower than those in the control group ( P < 0.05). The level of serum IGF‐1 was negatively correlated with HOMA‐IR, LSM, and APRI score in CHC with T2DM group ( r = −0.71, −0.75, and −0.69; P < 0.01). Conclusion The degree of hepatic fibrosis in patients with CHC combined with T2DM was higher than that in non‐T2DM patients with CHC, which was mainly related to insulin resistance (IR) induced by 1b genotype HCV infection. IR can lead to impaired synthesis of IGF‐1, and the degree of damage has a corresponding relationship with hepatic fibrosis. The degree of hepatic fibrosis in patients with chronic hepatitis C (CHC) combined with type 2 diabetes mellitus (T2DM) was higher than that in non‐T2DM patients with CHC, which was mainly related to insulin resistance (IR) induced by 1b genotype hepatitis C virus infection. IR can lead to impaired synthesis of insulin growth factor 1, and the degree of damage has a corresponding relationship with hepatic fibrosis.
