Multicenter Study
Bacterial meningitis: rapid diagnosis and microbial profile: a multicentered study.
Meningitis continues to be a formidable illness with high morbidity and mortality among children in India. The present study was undertaken to prospectively look for the prevalence of pyogenic meningitis at Gulbarga and to find out the utility of gram stain, Latex Agglutination Test and (LTA) and C-reactive protein in the rapid diagnosis of pyogenic meningitis from children. Over a 48-months period, 535 children with a presumptive clinical diagnosis of acute bacterial meningitis were investigated by direct microscopy, CRP, bacterial culture, latex agglutination test (L TA), cell count and cell type and biochemical tests. ⋯ Among 55 pretreated cases, only 05 (9.1%) CSF samples were culture positive, bacteria was observed in 36 gram stain smear, CRP was elevated in 16 CSF samples and 52 pretreated cases of suspected meningitis were diagnosed as pyogenic meningitis by latex agglutination test for detection of bacterial antigens. Many of the bacterial isolates were sensitive to gentamicin, cefotaxime and ceftriaxone and least sensitive to tetracycline and gentamicin. 13.1% of gram-negative bacilli were ESBL producers. To conclude, inclusion of latex agglutination test for detection of bacterial antigen in the routine diagnosis adds a valuable adjunct in the rapid and accurate diagnosis of pyogenic meningitis.
