ABSTRACT
The main objectives of this study are to evaluate the resistance rates of Streptococcus pneumonia to penicillin G, ceftriaxone and vancomycin in patients with meningitis; to analyze possible risk factors to the antimicrobian resistance; to describe the serotypes detected and to suggest an initial empirical treatment for meningitis. The sensitiveness and serotypes of all isolated S. pneumoniae of patients with acute bacterial meningitis received by the Paraná State Central Laboratory from April 2001 to august 2002 have been evaluated. One hundred S. pneumoniae have been isolated, of which 15 percent were resistant to penicillin, 1 percent to cephalosporin and 0 percent to vancomycin. The serotypes most found were 14 (19 percent), 3 and 23F (10 percent each). When only the resistant serotypes were analyzed, the most prevalent was the 14 with 44 percent. The risk factors found in relation to the S. pneumoniae resistance were age under one year old (p=0.01) and previous use of antibiotic (p=0.046). The resistance rates found, which were moderate to penicillin, low to cephalosporin and neutral to vancomycin, suggest the isolated use of a 3rd generation cephalosporin as an initial empirical therapy for the treatment of acute bacterial meningitis with a communitarian background.
RESUMO
Este estudo teve como objetivo avaliar as taxas de resistência de Streptococcus pneumoniae, isolados de pacientes com meningite, à penicilina G, ceftriaxona e vancomicina; avaliar possíveis fatores de risco para resistência antimicrobiana; descrever os sorotipos encontrados e sugerir a terapêutica empírica inicial para meningite. Foram isoladas 100 amostras de S. pneumoniae, encontrando-se 15 por cento de resistência à penicilina, 1 por cento à cefalosporina e 0 por cento à vancomicina. Os sorotipos mais encontrados foram 14 (19 por cento), 3 e 23F (10 por cento cada). Analisando-se os resistentes, o sorotipo 14 (44 por cento) também foi o mais freqüente. Os fatores de risco para resistência de S. pneumoniae encontrados foram idade menor que um ano (p=0,01) e o uso prévio de antibiótico (p=0,046). As taxas de resistência encontradas, moderada a penicilina, baixa para cefalosporina e nula para vancomicina, sugerem como terapêutica empírica inicial para tratamento da meningite bacteriana aguda de origem comunitária, a cefalosporina de terceira geração isoladamente.
