Restless legs syndrome in pediatric onset multiple sclerosis

Published:October 02, 2021DOI:https://doi.org/10.1016/j.msard.2021.103295

      Highlight

      • We investigated the prevalence of RLS/WED and to define the disease characteristics in young patients with pediatric onset multiple sclerosis (POMS).
      • Our study demonstrated high prevalence of RLS/WED in young patients with POMS. 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).
      • No statistical difference was detected about attack number, radiological features and laboratory data of OCB, ferritin levels, CRP, neutrophil-to-lymphocyte ratio, and 25-OH vitamin D.

      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.
