Celiac.com 02/09/2009 - Doctors are recommending simple, low-cost blood tests to screen for celiac disease in patients who have Restless Leg Syndrome (RLS) with low serum ferritin, but who otherwise show no clear cause for iron deficiency.

Low iron reserves are a known risk factor Restless Leg Syndrome, as blood iron levels below 45-50ng/mL have been tied to more severe expressions of RLS. In fact, iron levels are so important to assessing RLS, that it is now common for doctors to test blood ferritin levels when first assessing Restless Leg Syndrome. Celiac disease is a common genetic disorder of the immune system that can cause iron deficiency.

Doctors S. Manchanda, C.R. Davies, and D. Picchietti of the College of Medicine at the University of Illinois at Urbana-Champaign recently set out to determine if celiac disease might play a role in iron deficiency in patients with Restless Leg Syndrome.

The doctors evaluated a series of four patients with Restless Leg Syndrome and blood ferritin below 25ng/mL, who had shown positive blood tests for celiac disease. Doctors confirmed celiac disease for all four patients via
