Antibodies to Epstein-Barr virus and cytomegalovirus in Guillain-Barre syndrome.

Autor(es): Wahren B,Link H

Resumo: Twenty-three patients with Guillain-Barré syndrome (GBS) were investigated for serum antibody titres against Epstein-Barr virus capsid antigen (EBV-VCA), cytomegalovirus (CMV) and herpes simplex virus type 1 (HSV1). The geometric mean EBV-VCA titre was 45 in GBS, compared with 15-22 in healthy adults and 60 in sarcoidosis. Nine of the 15 GBS patients (60%) from whom multiple serum specimens were available, displayed a four-fold variation in antibody titre to EBV-VCA during the course of their disease. The geometric mean titres against CMV and HSV were also slightly higher in GBS compared with controls, but no titre variations were observed. Serial samples of both serum and cerebrospinal fluid (CSF) were available from 2 patients. Serum antibody titres against EBV were significantly higher in both during the initial phase of the disease. Serum antibody titres against CMV were also significantly elevated in 1 patient, but not until the second month after onset. The CSF antibody titres against EBV were higher in the beginning of the disease compared with the values during convalescence, but the titres observed were low. No measurable CSF antibody titres against CMV were found. The observation of varying serum antibody titres against EBV during the course of GBS can be interpreted as primary infections or as manifestations of reactivated latent virus infections. Further studies of the pathogenetic significance of this for the aetiology of the disease are warranted.
