It has been suggested that the immune-endocrine communication plays an important role in development and progression of multiple sclerosis (MS). Interferon beta (IFNβ-1b) treatment is the therapy of choice in patients suffering from relapsing remitting or secondary chronic progressive multiple sclerosis. While typical adverse events of IFNβ-1b treatment such as flu-like symptoms or fatigue are well studied, little is known about the acute changes in the immune and neuroendocrine system. Therefore, we analyzed the short-term effects of IFNβ-1b on cortisol, epinephrine, norepinephrine, prolactin and growth hormone (GH) plasma levels before and 4, 8 and 24 h after IFNβ-1b administration in healthy subjects. Moreover, we determined heart rate, blood pressure, body temperature, leukocyte and lymphocyte subsets and plasma levels of interleukin (IL)-1β, IL-6, IL-10 and tumor necrosis factor (TNF)-α. IFNβ-1b led to an increase in body temperature and heart rate, and in parallel, elevated cortisol, prolactin and GH plasma levels at 4 and 8 h after IFNβ-1b injection. There were no significant alterations in blood pressure, norepinephrine or epinephrine plasma levels. Simultaneously, IFNβ-1b injection led to an immediate granulocytosis while concomitantly decreasing peripheral lymphocytes, especially natural killer (NK) cells. At the same time, IL-6, IL-10 and TNF-α plasma levels showed an overall increase. Overall, cytokine administration exerts strong stimulatory effects on the hypothalamic-pituitary-adrenal (HPA)-axis that may contribute to the side effects of IFNβ-1b therapy and affect the efficacy of IFNβ-1b treatment.
