Suppurative meningitis should be recognized as being a complication of varicella. The clinician must assiduously exclude suppurative meningitis that at times may be clinically indistinguishable from the typical postinfectious encephalomyelitis of varicella. Misdiagnosis of the cause of CNS alterations during the course of varicella is possible.

The neurologic complications of varicella-zoster (VZ) virus infections are manifested as zoster with or without CNS involvement, encephalomyelitis, or ocular involvement. Usually the association of VZ virus in these conditions has been determined by finding VZ antibodies in the serum. In a few instances, VZ antibodies have been detected in the CSF. We report two cases of VZ virus infection followed by neurologic complications involving the CNS in which VZ antibodies were present in the CSF. These two cases underscore the need and value of determining the presence of VZ antibodies in the CSF in certain instances.

Postinfectious encephalomyelitis is an acute demyelinating illness that usually has its onset 3 to 7 days after the onset of a viral exanthem and has a monophasic course over 2 to 4 weeks. Recurrent bouts of postinfectious encephalomyelitis have been described that have resolved spontaneously or with short courses of steroid therapy. We report a patient who developed a chronic, steroid-dependent encephalomyelitis secondary to a varicella infection at 5 months of age.

In the brains and spinal cords of 153 adult patients dying with acquired immunodeficiency syndrome (AIDS) at New York and Memorial Hospitals a subacute encephalitis with multinucleated cells was present in 28% of all patients. This encephalitis was characterized by multinucleated cells primarily located in the white matter and associated with myelin pallor and sparse infiltrates of rod cells, macrophages, gemistocytic astrocytes and lymphocytes. The incidence per 12 month period ranged from 0 to 43% and significantly increased between 1983-84 (14%) and 1984-85 (43%). Recent virologic and pathologic studies suggest that this encephalitis may be caused by direct LAV/HTLV-III infection of the central nervous system (CNS). Cytomegalovirus encephalomyelitis and toxoplasmosis were the most common opportunistic infections (26% and 10%, respectively). Progressive multifocal leukoencephalopathy, herpes simplex ventriculitis, varicella-zoster leukoencephalitis and fungal infections were infrequent (less than 3% each). A nonspecific encephalitis with microglial nodules and with mild white matter changes occurred in 17%, vacuolar myelopathy in 29% and CNS lymphoma in 6%. Less than 20% of patients had either normal brains or terminal metabolic encephalopathies. This survey shows that neuropathologic complications of AIDS are frequent. Infections are the most common complication and are caused by probable LAV/HTLV-III infection, or by opportunistic organisms.

The case of a patient with encephalomyelitis and laboratory signs of a central nervous system herpes zoster infection without cutaneous lesions is reported. The diagnosis was supported by the serological evidence of intrathecal synthesis of specific antibodies against Varicella-zoster virus (VZV).

In recent years, herpes simplex virus has been recognized as an important CNS pathogen in neonates and adults. The recent development of effective antiviral therapy has substantially reduced the excessive morbidity and mortality associated with these infections. For neonatal herpes simplex infections, the current drug of choice is vidarabine. The results of ongoing clinical trials comparing vidarabine with acyclovir in neonatal herpes may lead to a change in the recommended therapy. In the adult, the therapy of choice for herpes simplex encephalitis is acyclovir. Although effective, the present therapies for herpes simplex infections of the CNS leave much room for improvement. In addition to the development of more effective antiviral drugs and less invasive diagnostic techniques, prevention of these often devastating infections will be important in reducing morbidity and mortality. The CNS diseases associated with varicella and herpes zoster may have a different pathogenesis. The implication for therapy in these diseases favors nonspecific supportive therapy in the varicella-associated syndromes. The few anecdotal reports of the use of vidarabine and acyclovir in herpes zoster encephalitis and the histopathologic evidence suggesting viral invasion of the CNS in many cases of zoster-associated neurologic syndromes makes the use of specific antiviral therapy in zoster encephalomyelitis more rational. However, appropriate therapeutic recommendations will have to be based on controlled clinical trials that have not yet been performed.

We studied 19 patients with postinfectious encephalomyelitis complicating natural measles-virus infections, and our results support the hypothesis that this demyelinating disease has a pathogenesis similar to that of experimental allergic encephalomyelitis. Early myelin destruction was demonstrated by the presence of myelin basic protein in cerebrospinal fluid, and lymphocyte proliferative responses to myelin basic protein were found in 8 of 17 patients tested. A lack of intrathecal synthesis of antibody against measles virus suggests that measles encephalomyelitis may not be dependent on virus replication within the central nervous system. Similar lymphoproliferative responses to myelin basic protein of lymphocytes from single patients with encephalomyelitis after rabies vaccine or after varicella or rubella virus infections suggest a common immune-mediated pathogenesis for the perivenular demyelinating disease that can follow the injection of neural tissues or infection by a variety of viruses.

A middle-aged woman had five discrete episodes of herpes zoster. The first attack consisted of uncomplicated herpes zoster ophthalmicus. The subsequent four episodes involved thoracic, cervical, and finally sacral dermatomes and were complicated by myelitis or encephalomyelitis. During the most recent attack, while she was receiving corticosteroids, varicella-zoster virus was cultured from the CSF. In addition, the patient had strong evidence of systemic lupus erythematosus, with a history of Raynaud's phenomenon, migratory arthralgia, and unexplained anemia before the first attack of zoster with subsequent development of a positive lupus cell preparation and elevated antinuclear antibody levels.

Varicella-zoster virus (VZV) was isolated on two occasions from the cerebrospinal fluid of an elderly woman with encephalomyelitis complicating thoracic zoster. Antibodies to ZV-induced membrane antigen (FAMA) were present in cerebrospinal fluid in a titer of 1:64; serum antibodies were 64-fold higher. Further evidence for local antibody production was derived from simultaneous measurements of immunoglobulin G and albumin in cerebrospinal fluid and serum and calculation of a cerebrospinal fluid-IgG index.
