Association analysis between variants of the interleukin-1beta and the interleukin-1 receptor antagonist gene and antidepressant treatment response in major depression.

ABSTRACT: This study investigated the possible association of the interleukin-1 beta (IL-1beta) C-511T promoter polymorphism and the interleukin-1 receptor antagonist (IL-1Ra) (86bp)(n) variable number of tandem repeats (VNTR) polymorphism with antidepressant response to paroxetine and mirtazapine treatment. The study group consisted of 101 patients suffering from DSM-IV major depression participating in a randomized double-blind controlled clinical trial. Patients homozygous for the IL-1beta-511T allele had a significantly faster and more pronounced response to paroxetine treatment than IL-1beta-511C allele carriers. No association was found for the IL-1beta C-511T polymorphism with mirtazapine treatment response. The IL-1Ra VNTR showed neither an association with paroxetine nor with mirtazapine tr
