[Guillain Barré- polyneuroradiculitis and Fisher-syndrome in cytomegalovirus infections (author's transl)].

In seven patients suffering from polyneuroradiculitis of the Guillain-Barré type and one case of Fisher syndrome, a cytomegalovirus infection was found. The elevation of the virus-specific IgM-antibodies was confirmed in all cases. The clinical course was severe and acute with respiratory disturbances, but complete remission occurred within 1-4 months. The complement fixing antibodies were highest during the first week of illness, so that further elevations could not be demonstrated, therefore making the IgM-antibody method of special importance. The role of cytomegalovirus infections in polyneuroradiculitis is also discussed.
