Features of the course of enteroviral infections with meningitis in adults during the epidemic season in 2013

Abstract

Solid sample of 135 patients aged of 15-17 years (54), 18-19 years (18), 20-59 years (63) with enteroviral infection and meningitis was examined. The peak of diseases was observed in July (43 persons), August (46), and September (22). The state of the moderate grade was in all patients. There were compared the frequency and severity of symptoms in individuals older than 20 years and adolescents aged 15-17 years. Initial pleocytosis in CSF - at day 1-3 (4-7th day in case of two-wave current) was less than 100 in 10, from 100 to 1000 in 40, more 1000 cells per 3 mm 3 - in 13 adult patients, including 17 - with a predominance of neutrophils (71 to 93% in cytosis of160-1584 cells per 3 mm 3). Enteroviral RNA in CSF was detected with the use of PCR in 132 patients, including 12 patients with cytosis of 3-28 cells in 3 mm 3. Maximum cytosis was 5952 cells per 3 mm 3 in patient of 17years old. In the peripheral blood of 28 patients there was noted leukocytosis of12,000-18,700 with a shift of the formula to the left. Most patients were discharged at the 9-13th day of the hospital stay. In 45,9% ofpatients the cases registered in Moscow were introduced from other regions and far abroad.
