Restless Leg Syndrome (RLS) is a common neuropathic disorder in patients with end stage renal disease (ESRD). Study Design: Because micronutrient depletion has been associated with RLS in ESRD and because the vitamin biotin is dialyzable, the investigators examined the relationship between biotin status and RLS in ESRD. Objectives: To assess the prevalence of biotin deficiency in those with and without RLS (Study 1) and to determine the effect of biotin supplementation on RLS symptoms (Study 2) in patients receiving chronic dialysis due to ESRD.

Condition Intervention
End Stage Renal Disease Restless Legs Syndrome Dietary Supplement: Biotin Supplementation Dietary Supplement: Sugar Pill

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: Biotin Deficiency and Restless Legs Syndrome: Evidence for a Causal Relationship From Randomized, Double-Blind, Placebo-Controlled Trial

Primary Outcome Measures:
  • Biotin Status of Dialysis Patients [ Time Frame: Measurement at baseline and after 8 weeks of treatment ]
    Biotin status is measured using Propionyl CoA carboxylase and Propionyl CoA carboxylase activation coefficients that are from isolated lymphocyte samples. This is a measurement that is independent of kidney function.

  • Change in Restless Legs Syndrome (RLS) symptoms after Biotin treatment [ Time Frame: Baseline RLS score measurement and measurement after 8 weeks of treatment ]
    The RLS is measured using the International Restless Legs Syndrome Scale, a validated tool for assessing severity of RLS in patient who have been diagnosed with RLS.

Detailed Description:
Setting and Participants: ESRD patients receiving chronic dialysis as outpatients at Saint Patrick Hospital in Missoula, Montana.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • ESRD requiring hemodialysis or peritoneal dialysis therapy for a duration of at least 3 months.

Exclusion Criteria:

  • History of consumption of more than 300 micrograms daily of biotin
  • Oral contraceptive therapy containing high amounts of estrogen because studies in rats provide evidence that high doses of steroid hormones reduce biotin status {Wang, 1997 #1634}
  • Women of childbearing age because of concern that biotin deficiency may be teratogenic {Mock, 2009 #2568}.
