Vitamin D immunomodulatory potential in multiple sclerosis.

Multiple sclerosis (MS) is an autoimmune disease of unknown etiology whose treatment is of limited efficiency and therefore has a high social burden. As it has been suggested that myelin destruction model, the clinical manifestation and the potential of therapeutic response in MS are correlated, it is quite justifiable that we study various factors (genetic, hormonal, environmental) that take part in the autoimmune process in order to improve the control over the disrupted immune regulation. Results from epidemiological and clinical studies clearly suggest that changes in vitamin D serum concentrations are correlated with the magnitude of the risk of developing MS, the phases of relapse and remittance and with gender differences in vitamin D metabolism.

Female sex hormones and cytokine secretion in women with multiple sclerosis.

Unlabelled: Data from experimental and clinical research suggest that sex hormones may influence the autoimmune process in multiple sclerosis (MS). Studies on the hormonal profile of patients with MS and its relation to the disease activity provide heterogeneous results.

Objectives: The aim of this study is to investigate the changes in serum levels of estradiol and progesterone and their correlations with the cytokine profile and the degree of disability in women with relapsing-remitting MS (RRMS).

Clinical and laboratory study of pro-inflammatory and antiinflammatory cytokines in women with multiple sclerosis.

Unlabelled: Multiple sclerosis (MS) is an autoimmune demyelinating disorder of the central nervous system characterised with a complex system of interactions between proinflammatory and anti-inflammatory cytokines in its course.

Aim: The aim of the present study was to investigate the serum levels of cytokines TNF-a, IFN-gamma, IL-4 and IL-10 in female patients with MS and healthy individuals, the changes occurring in the relapse and remission phases of the disease and their correlation with the severity of the neurological deficit.

Patients And Methods: Thirty-five women with relapsing-remitting MS were examined.

Female sex hormones and multiple sclerosis.

Multiple sclerosis is the most frequent debilitating neurological disease in young subjects. The autoimmune process predominantly affects females. This paper presents a review of experimental and clinical data about the effect of female sex hormones and conditions associated with hormonal alterations on the disease process.
