Brief Summary

Double-blind, placebo-controlled, entitled: "Intravenous Iron Metabolism in Restless Legs Syndrome

Detailed Description

To determine the effects of high-dose infusions of iron on Restless Legs Syndrome (RLS) symptoms and brain concentrations of iron.

Eligibility Criteria

Inclusion

  • Clinical diagnosis of Restless Legs Syndrome (RLS).
  • Presence of increased periodic leg movements of sleep (PLMS) before receiving treatment.
  • Patient sleep times are between 9pm and 9am.
  • Patient's RLS symptoms would occur daily if you were not on medication.

Exclusion

  • RLS secondary to other medical disorders as determined by history and physical/neurological examination.
  • On a treatment (e.g., psychiatric medication) that might significantly alter RLS symptoms or study results and who cannot discontinue medication for the extended period of the study.
  • History of multiple adverse drug reactions or specifically an allergy to IV iron.
  • Currently experiencing a serious medical condition (chronic organ failure, active inflammation or infection, congestive heart failure, etc.) that might alter iron metabolism, would place them at risk, or interfere with study participation.
  • An magnetic resonance imaging (MRI) is not possible because of medical reasons (Pacemaker; loose iron in the tissue) or concern about severe claustrophobia.
  • Any condition that is likely to increase iron loss (chronic bleeding, excluding menstruation; medically necessary phlebotomy) or consumption (pregnancy).
  • Serum ferritin \>300mg/L or percent iron saturation \>50%. This is to exclude subjects with probable hemochromatosis.
  • Significant medical (e.g., inflammatory bowel syndrome; bowel dysmotility syndromes) or surgical (e.g., gastrojejunal bypass, colectomy) GI tract problems; and active chronic inflammatory processes (e.g., active hepatitis, rheumatoid arthritis, systemic lupus erythematosus). This is to exclude conditions which will potentially alter iron metabolism.
