Nutritional profile of multiple sclerosis.

Background: multiple sclerosis (MS) is an inflammatory, neurodegenerative disease of the central nervous system. Weight loss and malnutrition are prevalent in advanced stages of MS. Objective: the aim of this study was to define the nutritional profile in moderate-advanced MS (especially by documenting malnutrition) and its evolution. Methods: a case-control study was designed; cross-sectional observational study was complemented by a 12-month prospective longitudinal observational study of MS patients. Nutritional status was evaluated by collecting clinical, anthropometric, dietary and analytical data. Results: one hundred and twenty-four patients with MS and 62 controls were recruited; 8% of the patients were malnourished or at risk of malnutrition. Only MS patients with advanced disability needed nutritional support. During the follow-up, five patients died and four of them received nutritional support. Conclusions: malnutrition was unusual in our sample of patients with moderate-advanced MS. The need for nutritional support is related to dysphagia in patients with advanced neurological disability. The nutritional status of patients with moderate-advanced MS is defined by a tendency to overweight and by the decrease in basal energy expenditure and handgrip strength test in relation to the loss of muscle mass. The deficient intake of polyunsaturated fatty acids, fiber and vitamin D is exacerbated in the evolution of the disease.
