Glatiramer acetate (GA) is effective in the treatment of Multiple Sclerosis (MS) presumably by the induction of an immunoregulatory T-cell response. We have previously shown that GA directly induces the Th2 cytokines IL-13 and IL-5 in T-cells in vitro. In the present study we compared the in vitro response to GA in healthy controls, untreated and GA-treated MS patients and tested whether the induction of IL-13 and IL-5 secretion is also detectable in the serum of 25 MS patients treated with GA. Patients were grouped into clinical responders and nonresponders in order to determine a possible correlation with the immunological response. As a result we found a significant increase of IL-13 in the serum of clinical GA-responders whereas IL-13 was not detectable in controls, untreated MS (P < 0.001) and nonresponders (P = 0.015). Similarly, GA-treatment increased serum levels of IL-5 (P = 0.001). The correlation of serum IL-5 and clinical response was also significant (P = 0.039), however, there was an overlap between the different groups. The selective induction of IL-13 and IL-5 but not IL-4 by GA treatment suggests that the specific biological functions of these cytokines might be important for the therapeutic mechanism of GA. Measurement of serum IL-13 and IL-5 levels is a simple and inexpensive tool for monitoring the response to GA in MS patients.
