One of these features is low serum ferritin. In this retrospective, pilot study, we assess the response to iron supplementation. Children were given oral ferrous sulfate (FS) or intravenous ferric carboxymaltose (IV FCM).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Children 5\u201318 years old with a diagnosis of RSD were evaluated clinically. Serum ferritin, iron profile, and video-polysomnography were obtained at baseline. Oral or IV iron supplementation was offered as part of routine care. Oral FS was one 325 mg tablet daily or 3 mg\/kg\/day liquid for 3 months. IV FCM was 15 mg\/kg, up to 750 mg as a single infusion. Adverse effects were assessed. Ferritin and iron profile were checked after 2\u20133 months. Eight weeks after FCM, the phosphorus level was checked. Clinical Global Impression (CGI) scale was obtained pre- and posttreatment.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>A total of 15 children received oral FS and 15 IV FCM. Baseline RSD severity, age, gender, or pretreatment lab values did not differ significantly between groups. CGI-improvement median score was \u201cminimally improved\u201d after oral FS and \u201cmuch improved\u201d after IV FCM (effect size 1.008, p &amp;lt; 0.023). All iron parameters were found to be significantly higher after intravenous iron treatment than oral iron, especially ferritin (effect size 3.743, p &amp;lt; 0.00003). Adverse effects: constipation, three with FS; noncompliance, one with FS; syncope, one with FCM infusion; and hypophosphatemia, zero post-FCM.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>In this retrospective, clinical case series, RSD responded to iron supplementation with improvement in both clinical and laboratory parameters.
