Additional investigation for autoimmune antibodies including antinuclear antibody (ANA), lupus double-stranded DNA, Sjogren’s anti-Ro (SS-A) and anti-La (SS-B), neuromyelitis optica (NMO), and myelin oligodendrocyte glycoprotein (MOG) were nonrevealing (Table 1). Here, SSB is linked to neuromyelitis optica.
