METHOD: We reviewed retrospectively the demographic, clinical, biological characteristics and outcomes of 11 patients with HSV meningitis.
RESULTS: Among the 11 patients, six were infected with HIV, four had a documented history of genital herpes, and one recurrent meningitis. In all cases, the onset of symptoms was abrupt, with severe headache and fever. On admission, 9/11 patients had severe meningismus; two patients had HSV anogenital ulcerations. CSF analysis showed in every case a significant increased of leukocytes with a lymphocytic pleocytosis, a mild elevated protein level and a normal glucose level. HSV was detected in the CSF in every case by PCR: the typing performed on six patients was positive in every case for HSV-2. Intravenous acyclovir (IV ACV) was started in 10/11 cases (range: 3-10 days), switched to valaciclovir (VACV) (range: 5-7 days); one patient was treated with ACV per os for 10 days. The total resolution of symptoms occurred within 48hours in every case. Two patients presented with recurrent HSV-2 meningitis in the next two months, with favorable outcome under IV ACV: a switch to long term VACV 500mg/day was prescribed without any recurrence. No patient presented with recurrence after a median follow-up of 30 months.
CONCLUSION: Early recognition and treatment might improve the outcome of such infections. Adjunctive oral VACV after IV ACV treatment seems to be associated with a good clinical response in patients presenting with HSV meningitis. The duration of such treatments, including prophylactic treatments to prevent recurrent episodes must be better documented.
