[Sandfly fever Naples virus (serotype Toscana) infection with meningeal involvement after a vacation in Italy].

HISTORY AND CLINICAL FINDINGS: A 69-year-old man was admitted to our hospital with severe headache, recurrent episodes of fever and deterioration of general health. He returned from a vacation in Tuscany (Italy) a few days before admission. Physical examination revealed slight nuchal rigidity and an elevated body temperature of 37.8 C but was otherwise unremarkable.

INVESTIGATIONS: Differential blood count showed a lymphocytopenia. Other abnormal laboratory findings included an elevated blood sedimentation rate and a slightly increased C-reactive protein value. Abdominal sonography demonstrated a marginally enlarged spleen.

DIAGNOSIS, TREATMENT AND CLINICAL COURSE: A lumbar puncture was performed. Cerebrospinal fluid analysis revealed a lymphocytic meningitis. Serological examination of a blood sample showed specific IgM-antibodies against sandfly fever Naples virus (SFNV), subtype Toscana virus (TOSV). After this diagnosis had been made initially instituted intravenous administration of antibiotics and antiviral medication were discontinued. The patient's symptoms improved rapidly under symptomatic treatment. Slight headaches without episodes of fever persisted for a few weeks without residual neurological symptoms.

CONCLUSIONS: A history of travel should always be sought in patients with clinical signs for meningitis. Considering the increasing spread and incidence of SFNV and its subtype Toscana in mediterranean countries, such virus should be kept in mind when treating patients who present such symptoms after returning from those countries during the summer season.
