Excess weight increases the risk of sarcopenia in patients with multiple sclerosis.

BACKGROUND: Multiple sclerosis (MS) is an autoimmune neurodegenerative disease. Nutritional status influences the course of the disease, however, its relationship with sarcopenia needs further investigation. The aim of the study was to identify patients with sarcopenia and assess its association with nutritional status and the clinical course of the disease. METHODS: The study assessed 110 patients submitted to evaluation of sociodemographic characteristics, level of physical activity, nutritional status, and presence of sarcopenia. The clinical course of the disease, age at onset, disease duration, disease-modifying therapy, and expanded scale of disability status (EDSS) were investigated. RESULTS: Mean age was 37.17 (SD = 10.60) years, disease duration was 6.29 years (SD = 4.65), with a predominance of female gender (80.90 %), relapsing-remitting clinical form (RRMS) (89.10 %) and mild level of disability (EDSS median = 1.92). The group had excess weight (53.6 %) according to body mass index (BMI) and abdominal fat accumulation measured by waist circumference (WC) (53.6 %). High percentage of fat mass ( % FM) was observed in 54.5 % and 38.2 % of the patients according to bioimpedance (BIA) and ultrasound (US), respectively. It was observed that 15.5 % were at risk for sarcopenia, which was associated with excess weight, and high % FM (p<0.05). CONCLUSION: These findings highlight the importance of including nutritional status indicators, and sarcopenia assessment in the care of patients with MS.

Cardiovascular risk estimated in individuals with multiple sclerosis: A case-control study.

BACKGROUND: Patients with multiple sclerosis (MS) had a 1.5-fold increase in cardiovascular diseases (CVD) mortality, compared with those without MS. Therefore, the aim of this study was to assess the CVD risk in MS patients by multiple cardiometabolic indexes and to investigate associated factors. METHODS: The MS group included 57 patients matched for age and sex to 57 healthy controls. They were evaluated for physical activity, smoking, anthropometric indices, blood pressure, and plasma biomarkers. Framingham risk score (FRS) and multiple cardiovascular risk indexes were calculated. Clinical course of disease, age at onset, disease duration, disease-modifying therapy, relapse rate, EDSS, physical and functional impairment were investigated. RESULTS: The mean age was 34.6 years old. The majority (89.5%) in the MS group had a RRMS clinical course and a mild level of disability (EDSS=1.0). WC (p = 0.022) and FM% (p = 0.007) were different between the MS and control groups. The FRS was higher in the MS group (10% versus 0%) and this was related with high prevalence of dyslipidemia (43.8% versus 36.8%). The atherogenic index of plasma (AIP) (0.013) and Castelli risk indexes I (CRI-I) (p = 0.017) and II (CRI-II) (p = 0.008) and non-HDL-C (p = 0.044) were higher in the MS group. CONCLUSION: MS patients, with controlled disease course, have a higher cardiovascular risk than comparable healthy individuals. We emphasize that the use of FRS, and the monitoring of CRI-I and II, as well as AIP, are important lipid markers to manage CVD risk in individuals with MS.
