We analyzed the sera of 51 patients with various phenotypes of X-linked adrenoleukodystrophy (X-ALD), 20 patients with multiple sclerosis (MS) and 22 healthy volunteers for the presence of autoantibodies specific for the recombinant extracellular immunoglobulin-like domain of human myelin oligodendrocyte glycoprotein (rhMOG(Igd)) and myelin basic protein (MBP). Anti-rhMOG(Igd) autoantibodies were significantly more frequent in X-ALD and MS patients as opposed to healthy individuals (p<0.05). Anti-MBP autoantibodies were present in about one-fourth of X-ALD and MS patients but in less than 10% of healthy individuals. Anti-rhMOG(Igd) autoantibody responses were not accompanied by increased T cell reactivity against rhMOG(Igd). These findings may have important implications for the understanding of humoral anti-myelin immunoreactivity in demyelinating diseases of the central nervous system such as X-ALD and MS.
