Fig. 2From: Anti-cytokine autoantibodies in postherpetic neuralgiaEvaluation of antibodies against VZV and EBV in the HZ and PHN cohorts. Serum samples were assayed for antibodies against VZV and EBV by LIPS. a The antibody levels against the gE glycoprotein antigen of VZV and b antibody levels to the p23 capsid protein of EBV in the HZ and PHN groups. For VZV antibodies, the dotted line represents the previously established cutoff value [16]. The red square corresponds to patient #226 (see Table 2) who is the IL-6 seropositive PHN patient who was seronegative for VZV antibodiesBack to article page
