Varicella zoster virus (VZV) is an uncommon but well recognized cause of neurological disease in HIV-infected patients. Analysis of cerebrospinal fluid (CSF) using the polymerase chain reaction (PCR) in HIV-infected patients presenting with neurological disease has increasingly allowed diagnosis of VZV-associated pathology. We report clinical, radiological and virological data from 15 consecutive patients with VZV-associated neurological disease. Clinical presentation was varied, including meningo-encephalitis in 9 and isolated cranial nerve palsies in 6. VZV deoxyribonucleic acid (DNA) was detected by PCR in CSF of 11/15; pleocytosis was present in only 6/15, raised protein in 11/15. Magnetic resonance imaging (MRI) appearances were focal signal abnormalities in 8, meningeal enhancement in 2 and normal in 2. With specific anti-VZV therapy 10 patients recovered fully. The predictive value of PCR on CSF for diagnosis of VZV-associated neurological disease should take into account the patient's clinical presentation, concurrent infections and response to anti-VZV therapy.

We present the case of a 48-year-old HIV-positive man, who developed acute onset of pain in both upper limbs associated with proximal weakness and distal paraesthesia. Eight weeks prior to this presentation he had had varicella zoster affecting his right S1 dermatome. CD4 count was 355 cells/mm(3) and he was antiretroviral therapy (ART) naive. Power was 0/5 proximally and 4/5 distally in the upper limbs. Reflexes were absent and there was sensory loss in the C5, C6 and T1 dermatomes. Cerebrospinal fluid (CSF) examination showed a lymphocytosis with low glucose; however, CSF Mycobacterium tuberculosis (TB), and herpes simplex virus polymerase chain reaction (HSV PCR) were negative as was syphilis serology. Electromyography showed marked motor axonal loss. Magnetic resonance imaging (MRI) did not show any cervical spinal lesion. Varicella zoster virus (VZV) PCR was positive in the CSF. He was treated with high-dose intravenous aciclovir with good resolution of his syndrome over time and was commenced on ART. We believe this to be the first case report of varicella reactivation causing bilateral neuralgic amyotrophy in an HIV-positive patient.

Varicella zoster virus (VZV)-mediated vasculitis is a rare cause of stroke, but should be considered in HIV patients where vasculitis can occur in association with central nervous system - immune reconstitution inflammatory syndrome (CNS-IRIS). A literature search revealed 7 reports of VZV vasculitis over the years with no unifying management strategy, highlighting the difficulty in managing rare conditions in the absence of clear guidelines. This is the first documented case of VZV-mediated vasculitis presenting as stroke in the United Kingdom. Our patient made a full recovery with multidisciplinary input from HIV, neurology and radiology specialists.
