ABSTRACTHerpes simplex virus 1 (HSV-1) and varicella-zoster virus (VZV) cause serious central nervous system (CNS) diseases that are diagnosed with PCR using samples of cerebrospinal fluid (CSF) and, during later stages of such infections, with assays of intrathecal IgG antibody production. However, serological diagnoses have been hampered by cross-reactions between HSV-1 and VZV IgG antibodies and are commonly reported in patients with herpes simplex encephalitis (HSE). In this study we have evaluated VZV glycoprotein E (gE) as a new antigen for serological diagnosis of VZV-induced CNS infections. Paired samples of CSF and serum from 29 patients with clinical diagnosis of VZV CNS infection (n= 15) or HSE (n= 14), all confirmed by PCR, were analyzed. VZV gE and whole VZV were compared as antigens in enzyme-linked immunosorbent assays (ELISAs) for serological assays in which the CSF/serum sample pairs were diluted to identical IgG concentrations. With the gE antigen, none of the HSE patients showed intrathecal IgG antibodies against VZV, compared to those shown by 11/14 patients using whole-VZV antigen (P< 0.001). In the patients with VZV infections, significantly higher CSF/serum optical density (OD) ratios were found in the VZV patients using the VZV gE antigen compared to those found using the whole-VZV antigen (P= 0.001). These results show that gE is a sensitive antigen for serological diagnosis of VZV infections in the CNS and that this antigen was devoid of cross-reactivity to HSV-1 IgG in patients with HSE. We therefore propose that VZV gE can be used for serological discrimination of CNS infections caused by VZV and HSV-1.

Herpes simplex virus type 1 (HSV-1) infections cause typical dermal and mucosal lesions in children and adults. Also complications to the peripheral and central nervous system, pneumonia or hepatitis are well known. However, dissemination to viscera in adults is rare and predominantly observed in immunocompromised patients. Here we describe the case of a 70-year-old male admitted with macrohematuria and signs of acute infection and finally deceasing in a septic shock with multi organ failure 17 days after admission to intensive care unit. No bacterial or fungal infection could be detected during his stay, but only two days before death the patient showed signs of rectal, orolabial and genital herpes infection. The presence of HSV-1 was detected in swabs taken from the lesions, oropharyngeal fluid as well as in plasma. Post-mortem polymerase chain reaction analyses confirmed a disseminated infection with HSV-1 involving various organs and tissues but excluding the central nervous system. Autopsy revealed a predominantly retroperitoneal diffuse large B-cell lymphoma as the suspected origin of immunosuppression underlying herpes simplex dissemination.
