[C-reactive protein, lactate and LDH isoenzymes in the cerebrospinal fluid in the diagnosis in childhood meningitis]. / La proteína C reactiva, el lactato y los isoenzimas de la LDH a nivel del LCR en el diagnóstico de las meningitis infantiles.

C reactive protein lactate and LDH isoenzymes were quantified in CSF of 32 children with meningitis (27 bacterial and 5 viral). Results in cases with bacterial meningitis were as follows. C reactive protein sensitivity was 11.1% and specificity was 100%. Lactate sensitivity was 33.3% and its specificity was 80%. LDH1 and LDH5 had a sensitivity of 44.4%, and specificities of 100 and 60% respectively. Considering these results an has believe that none of these tests is definitive in diagnosis of bacterial meningitis in children.
