Body composition in ambulatory patients with multiple sclerosis.

The aim of this study was to compare between ambulatory patients with multiple sclerosis (MS) and control subjects, bone mineral density (BMD), and body composition, that is, percent of bone minerals (M%), fat (F%), and remaining substances (L%). Total body composition and BMD were measured by dual-energy X-ray absorptiometry in 68 patients with definite MS and Expanded Disability Status Scale (EDSS) score ≤ 6.5 (41 females and 27 males) and 114 control individuals (72 females and 42 males). The amount of F%, L%, M%, and BMD in the whole body, arms, and trunk was not statistically different between MS patients (males and females) and controls, except in the lower extremities of female patients where there was increased F% and reduced L% compared with controls. There were no correlations between F%, L%, M%, and BMD at any anatomic region with EDSS or the cumulative corticosteroid dose. The reduced L% in the lower extremities of female patients suggests a possible increased subsequent risk of osteoporosis in the legs. Brief steroid courses administered during disease exacerbations in ambulatory MS patients did not result in obvious adverse consequences. Copyright Â
