[Diagnostic difficulties in herpes simplex encephalitis patients: report of three cases].
Herpes simplex encephalitis (HSE) is a rare infection of the central nervous system. The prognosis is poor, even in those receiving anti-herpetic therapy (about 20% of patients die, and in 40% of cases neurological sequelae are severe). The diagnosis is based on clinical signs of encephalitis, typical pathological changes in MRI, and on the presence of anti-HSV antibody and/or HSV-DNA in the cerebrospinal fluid. Three cases of encephalitis are presented. The clinical course and pathological changes in the temporal lobes seen in MRI were characteristic of the HSV etiology. Early intrathecal synthesis of anty-HSV antibodies were not detected despite an increase in their serum level in the course of the disease. HSV-DNA detection with PCR was not performed. Nevertheless in all cases aciclovir therapy was introduced on the first day of hospitalization. Possibilities of diagnosing HSE on the basis of clinical signs and MRI scans during the first week of the disease are discussed, as well as the tissue whether the course of treatment would be changed accordingly to the PCR test results.
