Summary: A new and controversial hypothesis suggests disease progression in MS may be related to CCSVI and the resulting toxic effects of parenchymal iron deposition in the central nervous system (CNS; Singh AV, Zamboni P, J Cereb Blood Flow Metab 2009;29:1867-78). When iron is present in the CNS, it simulates intrathecal expression of ferritin (Keirg et al, Clin Chim Acta 1993;216:153-66). An indirect test for deposition of iron in the CNS is quantification of ferritin.
The authors postulated that if CSSVI leads to parenchymal iron deposition in MS, there ought to be increased CSF ferritin levels. They quantified CSF ferritin levels from a previously published cohort with clinically definite MS (Petzold A, et al, Brain 2002;15:1462-473; Polman CH, et al, Ann Neurol 2005;58:840-6)....
