Selected cytokine profiles during remission in bipolar patients.

The aim of the study was to examine the cytokine status in bipolar patients during immediate remission after acute episodes of mania or depression and in patients with sustained (≥6 months) remission, compared with healthy controls. The study was performed on 121 bipolar patients, of whom 35 were in immediate remission after mania, 41 were in immediate remission after depression, and 45 were in >6-month remission on lithium monotherapy or lithium combined with other drugs. The control group consisted of 78 healthy individuals without any history of psychiatric or immunological illnesses. Serum concentrations of IL-1β, IL-2, IL-6, IL-10, TNF-α and IFN-γ were determined using the Human Th1/Th2 Cytometric Bead Array method. The concentration of IL-10 was higher in patients in remission after mania and the concentration of IFN-γ was higher in those in remission after depression than in healthy controls. On the other hand, cytokine concentrations in patients with sustained remission were not different from those of healthy subjects. The results obtained in this study show that sustained remission in bipolar patients achieved mostly by lithium maintenance brings the cytokine status to a level similar to healthy control subjects.
