Introduction and objectives: In this study, we aimed to evaluate LIF levels and its possible relationship with disease activity in patients with Takayasu's (TAK) and Giant cell arteritis (GCA) patients. Materials and methods: 23 Takayasu's arteritis, 9 Giant cell arteritis patients and 25 healthy volunteers were included in the study. Serum LIF levels were measured ELISA. Results: The mean age of Giant cell arteritis patients was statistically significantly higher than the other groups (p < 0.001). The rate of women was found to be higher in Takayasu's arteritis (p = 0.021). When healthy control, patients with GCA and Takayasu arteritis were compared, there was a difference in LIF values (p = 0.018). In subgroup analyzes, LIF values were found to be higher in GCA patients compared to healthy controls (p < 0.05). There was no statistically significant correlation between LIF and CRP (Rho = −0.038, p = 0.778), ESR (Rho = 0.114, p = 0.399) and ITAS (Rho = −0.357, p = 0.094). While CRP was statistically significantly higher in patients with disease activity (p = 0.003), there was no statistically significant difference between patients in terms of ESR and LIF values. While there was a statistically significant relationship between CRP (OR = 1.19 [1.03–1.37], p = 0.018) and disease activity in univariate analyses, no statistically significant variable was found in multivariable analyses. Conclusions: LIF values were significantly higher in patients with Giant cell arteritis compared to healthy controls.
