Peripheral levels of selected adipokines in patients with newly diagnosed multiple sclerosis.

Introduction: Multiple sclerosis (MS) is an autoimmune disease of the central nervous system. The exact aetiology is unknown. However, genetic and environmental factors are suggested to be involved in the pathogenesis of MS. Improper diet, resulting in obesity and metabolic syndrome, can contribute to this disease. Adipokines, secreted by adipose tissue, link the metabolism and immune system. Material and methods: We aimed to assess plasma levels of selected adipokines in newly diagnosed, treatment-naive individuals with multiple sclerosis. Our group comprised 58 individuals (31 MS patients and 27 controls, matched for age and BMI) without diabetes, hypertension, or dyslipidaemia. Circulating adiponectin and all adiponectin fractions, visfatin, and omentin concentrations were measured. Metabolic parameters were also assessed. Results: In MS individuals we observed the following results: higher concentrations of visfatin, lower levels of omentin, and no differences in adiponectin array. There were also correlations between some adipokines and metabolic parameters. After adjustment to BMI, a significant decrease in total adiponectin, high-molecular weight (HMW) adiponectin and omentin, and an increase in medium-molecular-weight (MMW) adiponectin were observed in the group of MS patients when compared to those of the controls. Conclusions: Our results indicate that adiponectin with its fractions, visfatin, and omentin cannot be considered as causative factors in the early phase of multiple sderosis. However, the potential role of adipokines in MS is possible because they might be involved in the pathogenesis of MS, regarded as an autoimmune disorder.
