The pathophysiology of bipolar disorder (BD) includes, among other processes, changes in the neuroplasticity and regulation of apoptosis, which could potentially be influenced by inflammatory mediators such as chemokines. The objectives of this study were to investigate serum chemokine levels in patients with BD and to compare results with those obtained with healthy subjects. Here, serum chemokine levels of 30 euthymic patients with BD type I and 30 healthy volunteers were investigated and compared. The chemokines assessed were CCL2, CCL3, CCL8, CCL 9, CCL10, CCL11, and CCL24. Patients with BD showed significant differences in chemokine levels when compared with healthy subjects. While serum levels of CXCL10 were increased (p = .018), CCL24 levels were lower in bipolar patients (p = .025) when compared with controls. There was no statistical difference in the serum levels of CCL2, CCL3, CCL24, CXCL9, and CXCL11 between patients and controls. The presence of chemokine abnormalities in patients with BD during euthymia suggests that these inflammatory mediators should be further investigated with regard to their potential role as longstanding markers of the disorder.
