T-helper 1/T-helper 2 cytokine imbalance and clinical phenotypes of acute-phase major depression.
Several studies have discussed the relationships between T-helper 1 (Th1) or Th2 cytokines and major depression. The aim of the present study was to investigate the relationships between Th1/Th2 cytokine balance and clinical phenotypes of acute-phase major depression. A total of 82 subjects including 42 patients with major depressive disorder and 40 healthy controls were recruited. Serum cytokine levels of interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha) and IL-10 were examined. Using ancova with age and body mass index (BMI) adjustments, there were no significant differences in serum IL-1beta, TNF-alpha, and IL-10 levels between patients with major depressive disorder and healthy controls. However, using ANCOVA with BMI adjustment only, the results showed that patients with major depressive disorder had significantly higher TNF-alpha levels than control subjects. In addition, using ANCOVA with age and BMI adjustments, significantly higher serum IL-1beta level and IL-1beta/IL-10 ratio were noted in patients with melancholic features than patients with non-melancholic features. However, there were no significant differences in serum IL-1beta, TNF-alpha and IL-10 levels between patients with and without suicide attempt. In conclusion, serum TNF-alpha, IL-1beta level and IL-1beta/IL-10 ratio might play an important role in the psychopathology of acute-phase major depressive disorder.
