Background. Herpesviruses are ubiquitous and commonly cause neurological syndromes. A paucity of data exists describing the clinical profiles and outcomes of these viruses in cerebrospinal fluid (CSF).
Objectives. To describe the clinical profile and outcomes of patients with a positive CSF viral panel testing for six herpesviruses (herpes simplex virus 1 and 2 (HSV1; HSV2), varicella zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV) and human herpesvirus 6 (HHV6)).
Methods. A retrospective descriptive study included all hospitalised patients aged 13 years and older in whom a herpesvirus was detected by a herpesvirus panel performed on CSF. A folder review was performed to acquire demographic, clinical and laboratory information.
Results. We identified 204 CSF herpesviruses in 184 patients. Most were people living with HIV (n=137/184, 74.5%). EBV was the most frequently identified herpesvirus (n=152/204, 74.5%). The herpesvirus was considered the cause of the clinical neurological syndrome in 20 patients (20/184, 10.9%), of whom most had VZV (7/20, 35%). Patients with VZV presented with encephalopathy (4/11, 36.4%), meningoencephalitis (3/11, 27.3%) and stroke (3/11, 27.3%). Encephalopathy, seizures and lower-limb weakness (n=5/19, 26.3%) were more common in patients with CMV. Those with HSV1 presented with seizures (n=2/5, 40%) and those with HSV2 with encephalopathy (n=3/6, 50%) and meningoencephalitis (n=2/6, 33.3%). EBV was the most common herpesvirus in patients with tuberculosis (TB) (45/49, 91.8%). Antiviral therapy was prescribed in 19/184 (10.3%) patients. The in-hospital mortality rate of all patients was 21.7%.
Conclusion. EBV was the most common herpesvirus detected on CSF. Most patients with TB and HIV had EBV detected in their CSF, which may represent reactivation in these patients. This study highlighted the undertreatment of CMV and overtreatment of EBV. Greater awareness regarding the clinical indications for antiviral therapy in this setting is needed.
