Arq Neuropsiquiatr 2003;61(3-B):728-730 FREQUENCY OF LYMPHOCYTIC MENINGITIS ASSOCIATED WITH MUMPS BEFORE AND AFTER A MASS CAMPAIGN FOR MUMPS VACCINATION IN

ABSTRACT- Objective: To describe the frequency of lymphocytic meningitis(LM) concomitant with mumps, before and after the mumps mass immunization campaign in 1997. Method: Demographic, clinical and cerebrospinal fluid(CSF) information was collected from the chart of all patients aged from 2 to 59 months, whose CSF exam was performed at the CSF Lab/FJS, between 1989 and 2001. LM was defined as pleocytosis composed by lymphomononuclear cells and negative exams for bacterial or mycologic infection. Results: Of 1,519 patients, 894(58.9%) had normal exams. LM was present in 301(19.8%) patients, out of which 22(7.3%) had concomitant mumps. The frequency of LM ranged from 15.8 % in 1989 to 19.7 % in 2001 and of LM with concomitant Mumps ranged from 10.5 % in 1989 to 4.7 % in 1995, when the last cases were registered. Conclusion: It is probable that the mumps vaccine campaign has influenced the absence of LM with concomitant Mumps, from 1996 to 2001. KEY WORDS: meningitis, mumps, immunization, cerebrospinal fluid, lymphocytic meningitis.
