The study included 90 participants divided into three groups: 40 patients with hypothyroidism, 26 patients with hyperthyroidism, and 24 healthy controls. Serum IL-6 and IL-23 concentrations were measured, A significant difference in serum IL-6 levels was observed among the three groups (F = 8.709, P < 0.001). The highest mean IL-6 concentration was recorded in the hyperthyroid group (46.7693 +/- 43.0165), followed by the control group (33.9306 +/- 31.2150), whereas the hypothyroid group showed the lowest concentration (16.6500 +/- 11.6646). Tukey's test demonstrated a significant difference between the hypothyroid and hyperthyroid groups, while the control group was not significantly different from either group. Serum IL-23 levels also differed significantly among the groups (F = 4.803, P = 0.011). The hyperthyroid group had the highest mean IL-23 concentration (26.9527 +/- 23.2794), followed by the control group (21.4263 +/- 11.3879), and the hypothyroid group had the lowest concentration (15.3270 +/- 8.9544).
