Investigation of anti-N-methyl-D-aspartate receptor and anti-myelin oligodendrocyte glycoprotein antibodies in patients with human herpesviruses-associated central nervous system infections

Human herpesviruses (HHVs) cause central nervous system (CNS) infections; however, the role of neural autoantibodies remains unclear. We aimed to assess the presence of anti-N-methyl-D-aspartate receptor (anti-NMDAR) and anti-myelin oligodendrocyte glycoprotein (MOG) antibodies in HHV-associated CNS infections. Seventeen adults with HHV DNA in the cerebrospinal fluid were tested using flow cytometry-based assays. None of the patients tested positive for anti-NMDAR antibodies. Anti-MOG antibodies were detected in two patients with VZV-associated CNS infection, one appearing after deterioration and the other at onset. Both patients recovered without sequelae. Anti-MOG antibodies may arise in VZV-associated CNS infections, warranting the consideration of autoimmune mechanisms.
