In order to study the long-term course after herpes simplex virus type 2 (HSV-2) meningitis and/or myeloradiculitis the records of 40 consecutive patients were studied. During the year following the acute phase, verified or suspected neurologic recurrences were noted in nearly half of the patients: 1 or more episodes of recurring meningitis were noted in 8 patients; new episodes of myelitis or radiculitis in 3; distinct attacks of headache in 4; and diffuse neurologic complaints impairing daily life in 3. Recurring mucocutaneous symptoms were observed in 16 patients. Eleven patients experienced concurrent or separate episodes of recurring mucocutaneous and neurologic symptoms, 7 had neurologic recurrences only and 5 had only mucocutaneous recurrences. As considerable morbidity may result, patients with HSV-2 meningitis and/or myeloradiculitis should be identified by means of thorough history-taking, careful examination and a specific viral diagnosis in order to enable adequate advice and counseling to be provided and to aid decision-making regarding antiviral therapy.
Forsgren et al. (2002) studied this question.
