The remaining 2 cytokines/chemokines that were not influenced by age, G-CSF and FGF-2, exhibited significant differences between TAK and GCA without significantly different levels between HD-TAK and HD-GCA [G-CSF: TAK vs. GCA, 28.3 (17.8–66.5) pg/mL vs. 0.3 (0–13.7) pg/mL, p = 0.003, HD-TAK vs. HD-GCA, 26.2 (0–36.5) pg/mL vs. 8.7 (0–26.3) pg/mL, p = 0.49; FGF-2: TAK vs. GCA, 70.0 (47.1–111.6) pg/mL vs. 38.0 (30.8–45.4) pg/mL, p < 0.001, HD-TAK vs. HD-GCA, 63.2 (21.3–82.7) pg/mL vs. 21.2 (2.8–40.8) pg/mL, p = 0.080]. The gene discussed is CSF3; the disease is temporal arteritis.
