IL‐12 is a cytokine that induces Th1‐derived cytokines (interferon‐gamma (IFN‐γ) and IL‐2). The significance of IL‐12 in human autoimmunity is no clear, and the serum levels of IL‐12 in SLE are not clearly established. Therefore, we examined the levels of IL‐12 in 39 patients with active SLE, with sandwich ELISA. The levels of IL‐12 in patients were significantly higher than in normal subjects. Patients with high levels of IL‐12 also had high levels of IFN‐γ, while their levels of IL‐13 were significantly lower than in patients with normal levels of IL‐12. Patients with pulmonary involvement had high levels of IL‐12, and steroid therapy decreased the IL‐12 level in three patients. In a retrospective study of seven patients, various changes of IL‐12 and IL‐13 were recognized before disease flare. Thus, in SLE patients, the level of IL‐12 was increased and this increase was related to the change of Th1‐ or Th2‐derived cytokines with some organ involvement.
