   Abstract 

Meningitis caused by varicella zoster virus (VZV) is quite rare among young immunocompetent adults though immunocompromised patients are often seen to be affected by reactivation of VZV presenting with primary clinical features of dermatomal rashes and neurological sequelae. Here, we report the clinical scenario of a young, healthy male who had presented with fever, headache, and onset of dermatomal rashes later than the fever and was eventually diagnosed to be a case of VZV meningitis. We would like to highlight the fact that even young immunocompetent patients though rarely, might contract VZV meningitis and clinicians should have a high index of suspicion and keen eyes to catch the more obvious features of VZV infection on complete physical examination and must not harbor any reservations in ordering polymerase chain reaction for VZV DNA or initiating aggressive antiviral therapy.

   Introduction Top


Infections by herpes viruses (herpes simplex Type 1 or 2, varicella zoster virus [VZV]) are frequent in humans, and such viruses tend to persist within cranial nerves, dorsal roots, and autonomic ganglia causing latent infections by virtue of reactivation.[1],[2],[3] Reactivation of VZV mainly presents with rash and pain affecting the entire dermatome and less frequently a zoster sine herpete.[1],[2],[3] VZV infection of the central nervous system (CNS) such as encephalitis, meningitis, myelitis, or vasculitis occurs rarely but is feared because of the numerous unfavorable outcomes of such presentations.[1],[3],[4] Reactivation of VZV is seen predominantly in older individuals and/or immunocompromised patients.[1],[2],[3] CNS infection with VZV in young immunocompetent adults is rare and unexpected, and only very few cases have been described so far in the world literature.[5],[6],[7],[8],[9] We bring to limelight, the scenario of a young immunocompetent patient with VZV meningitis.


   Case Report Top


A 33-year-old healthy Indian male employed as a software engineer developed intermittent holocranial throbbing headache, which soon progressed to severe continuous headache, associated with fever, photophobia, and vomiting for a duration of 3 days. He also complained of rashes over the skin of his left shoulder blade and left side of his body which was of the same duration. There was no past history of similar illness, contact with people having similar complaints, or chicken pox. There was no history of any other comorbidity. On examination, the patient was febrile, had neck stiffness and photophobia, and was found to have rashes along the cutaneous distribution of two lower intercostal nerves of the left side. Rest of general and systemic examination was unremarkable. His complete blood count was unremarkable except for raised erythrocyte sedimentation rate (30 mm/1st h). Renal function tests, liver function tests, and serum C-reactive protein were also reported normal. Serologies for dengue, typhoid, malaria, infectious mononucleosis, toxoplasma, rubella, cytomegalovirus, and herpes simplex antibodies were negative. Human immunodeficiency virus (HIV) serology was negative. Magnetic resonance imaging of the brain was normal. The cerebrospinal fluid (CSF) analysis showed cell count of 535 cells/µl CSF (differential count: 99% lymphocytes, 01% polymorphs), CSF protein was 115 mg/dl, CSF glucose was 34 mg/dl, and plasma glucose 76 mg/dl. CSF adenosine deaminase level was within normal limit (1 U/L). CSF Grams stain, Ziehl–Nielsen's acid-fast bacilli stain, India ink stain, cryptococcal antigen, common bacterial antigen assay (Haemophilus influenzae B, Streptococcus Group B, Streptococcus pneumoniae, Neisseria meningitidis A CYW 135, N. meningitidis B, and Escherichia coli), venereal disease research laboratory, and polymerase chain reaction (PCR) for tuberculosis were negative. CSF- PCR assays for herpes simplex I and II, enterovirus, and Mycobacterium tuberculosis were negative. CSF culture was negative for pyogenic organisms and tuberculosis. However, PCR for VZV conducted on blood and CSF was reported positive. He was treated with a broad spectrum antibiotic (ceftriaxone) and intravenous acyclovir (dose of 10 mg/kg body weight every 8 h) for 6 days. Gradual improvement in the condition of the patient was observed from 3rd day after initiation of parenteral acyclovir. He was discharged after in stable condition on oral acyclovir for 15 days.


   Discussion Top


Most neurological complications caused by VZV can occur in both primary and reactivated VZV although they seem to appear more frequently in herpes zoster than in VZV. Both immunocompetent and immunocompromised patients may suffer from these neurological complications, but they appear to be more frequent and more severe in the latter group. The common neurological complications associated with herpes zoster are postherpetic neuralgia, myelitis, encephalitis, ventriculitis, aseptic meningitis, and white-matter disease.[10] Meningitis is a rare complication of VZV infection In a review of 859 patients with varicella-zoster infection; meningitis was reported in only 0.5% within 60 days of diagnosis incidence increases with age including 2.5 cases/1000 in ages 21–50 versus 10.1 cases/1000 in those older than 80 years.[11] The incidence is increased in HIV-seropositive patients including 29.4 cases/1000 person-years as compared to the HIV-seronegative patients with 2.0 cases/1000 person-years.[12] Although the incidence of varicella and complications has decreased since the licensure of the vaccine, there may be breakthrough cases of varicella with aseptic meningitis and transient sensorineural hearing loss.[13] Patients with VZV meningitis may suffer from high fever, severe headache, cervical rigidity, seizure, ataxia, hemiplegia, and even coma; these symptoms may appear within days after the appearance of the skin lesion and sometimes without skin lesions also. CSF shows increased cell counts and elevated protein levels in the CSF [10] using sensitive laboratory analyses (e.g., PCR and detection of intrathecal production of specific antibodies), recent epidemiological studies found a portion of 5–29% of VZV in aseptic meningitis and encephalitis and it has been suspected that VZV infections had been underestimated in earlier publications.[9] Nevertheless, in immunocompetent patients without neurological deficits (as in our case), VZV meningitis is rare. We, therefore, highlight the importance of considering VZV as a possible cause for meningitis even in previously healthy young patients and the recommended diagnostic lumbar puncture. Detailed CSF diagnostic procedures including PCR and detection of intrathecal synthesis of antiviral antibodies (especially for VZV and herpes simplex viruses) should be considered even though CSF cell count and total protein seem to indicate a bacterial infection.[14] Since herpes zoster is a viral disease, conservative care or acyclovir administration is the routine treatment, and steroid therapy is employed as an optional addition. The administration of acyclovir within 48–72 h of the appearance of zoster effectively relieves acute pain and the vesicles, induces a higher rate of remission, and deters the virus from spreading throughout the patient's body, and they usually show a full recovery without developing other complications.[10]
