ABSTRACT
BACKGROUND: Restless legs syndrome/Willis-Ekbom disease (RLS/WED) was shown to have a high prevalence among adults with multiple sclerosis (MS).
OBJECTIVE: We aimed to investigate the prevalence of RLS/WED and to define the disease characteristics in young patients with pediatric onset multiple sclerosis (POMS) METHOD: 50 patients with POMS were questioned for the presence of RLS/WED. The demographic, clinical and laboratory data were compared between POMS patients with and without RLS/WED, including the total number of clinical and/or radiological MS attacks, interval between first two attacks, EDSS, number of the hyperintense and/or contrast-enhancing lesions, localization of demyelinating lesions, IgG index in cerebrospinal fluid, oligoclonal band, serum ferritin, C-reactive protein, ratio of neutrophil to lymphocyte count, and 25‑hydroxy vitaminD.
RESULTS: Eleven patients (22%) had RLS/WED – mostly of moderate in severity (54.5%). Mean EDSS score was significantly higher in POMS patients with RLS/WED than those without (p = 0.003). The Ig G index was almost two times higher in POMS patients with RLS/WED, but it failed to reach to the statistically significant level (p = 0.073).
CONCLUSION: Our study demonstrated high prevalence of RLS/WED in young patients with POMS. Higher EDSS scores in patients with POMS and RLS/WED indicates disease-related factors in the emergence of RLS/WED.
