Young patients with both type 1 diabetes mellitus and asthma have a unique IL‐12 and IL‐18 secretory pattern. Background: The expression of the regulatory cytokines interleukin (IL)‐12 and IL‐18 in patients with both Th1‐ and Th2‐mediated diseases, type 1 diabetes mellitus (T1DM) and asthma, is unknown. Objective: To investigate the in vivo and in vitro IL‐12 and IL‐18 secretion patterns in patients with both T1DM and asthma. Methods: Peripheral blood mononuclear cells (PBMC) were collected from 44 patients. Mean age 19.4 ± 4.7 yr (10.5–28 yr), divided into four paired groups: T1DM and asthma, asthma only, T1DM only, and healthy controls. T‐cell proliferative response was assessed. IL‐12 and IL‐18 serum levels and expression by PBMC following in vitro stimulation by lipopolysaccharide (LPS) were determined by enzyme‐linked immunosorbent assay (ELISA). Results: Patients with T1DM and asthma had higher serum levels of both IL‐12 and IL‐18 compared to controls: 146.2 ± 69.2 and 109.7 ± 34.6 pg/mL, p = 0.038 and 436.1 ± 117.9, 320.2 ± 99.1 pg/mL, p = 0.028, respectively. Stimulated IL‐12 secretion was significantly lower in these patients compared to those with one disease only: 809 ± 426.4, 2111.6 ± 2214.3, 3188.1 ± 2692.9 pg/mL and after 48 h: 956.3 ± 489.3, 2429.8 ± 2394.6, 3874.5 ± 2820.3 pg/mL, respectively, p < 0.03 for all. The IL‐18/IL‐12 serum ratio was also significantly higher in patients with both diseases compared to those with asthma only, p = 0.017. Conclusion: Patients with both T1DM and asthma display a different pattern of IL‐12 and IL‐18 expression compared to patients with one disease only and controls.
