Short-term sequential analysis of sex hormones and helper T cells type 1 (Th1) and helper T cells type 2 (Th2) cytokines during and after multiple sclerosis relapse.

摘要

Multiple sclerosis (MS) is an immune-mediated disease with a clear sex-bias that may be attributed to sex hormones, sex' linked genes or both. Here we sought to determine the evolution pattern of cortisol and sex hormones at MS relapse and 2-months later in 7 male patients with relapsing remitting MS, and whether there was a correlation with a specific Th1 and Th2 cytokine pattern. Our findings indicate the activation of the hypothalamic-pituitary-adrenal axis and the concomitant upregulation of pro- and anti-inflammatory cytokines during relapse. The further increase of sex hormones, in particular estradiol in our male MS patients suggest their possible implication in the physiopathology of the illness and a putative anti-inflammatory and neuroreparatory effect.
