Abstract

Background: Herpes zoster meningitis and meningoencephalitis, rare complications of herpes zoster, may follow the onset of rash, precede it, or even occur without rash. There have been few studies describing the order of occurrence of neurological symptoms and zoster.
Objective: We compared the clinical and laboratory features, treatments, and progress of the conditions among patients with herpes zoster meningitis and meningoencephalitis according to the timing of zoster onset in relation to neurological symptoms and also according to the immune status.
Methods: We performed a retrospective review of 21 patients with meningitis and 3 patients with meningoencephalitis who showed the characteristic rash of herpes zoster at National Health Insurance Service Ilsan Hospital between March 2000 and June 2015.
Results: The 11 patients in whom zoster preceded neurological symptoms had a shorter duration of neurological symptoms (median 3 days; range 1∼10) than did the 13 patients who experienced neurological symptoms first (median 10 days; range 4∼27) (p＜0.05). The intervals between the onset of neurological symptoms and a) presentation to the hospital, b) cerebrospinal fluid tests, and c) intravenous acyclovir treatment were all shorter in the patients with zoster preceding neurological symptoms (p＜0.05). No significant differences in age or immune status were observed between the two groups. In the 9 immunocompromised patients, higher incidence of meningoencephalitis and neurologic complications was noted in comparison to the 15 immunocompetent patients (p＜0.05).
Conclusion: Antecedent zoster rash in varicella zoster virus-induced meningitis and meningoencephalitis appears to lead to more rapid initiation of diagnostic tests and antiviral treatment. The possibility of central nervous system complications should not be overlooked even in patients with herpes zoster.
