8-hydroxy-2--deoxyguanosine and Meningitis--Bacterial

To examine the involvement of reactive oxygen species, we measured the concentration of 8-hydroxy-2'-deoxyguanosine (8-OHdG), a biomarker of oxidative stress, in cerebrospinal fluid samples from 63 children with and without meningitis. We observed that the mean concentration of 8-OHdG in samples obtained during the early phase of bacterial meningitis, but not aseptic meningitis, was significantly higher than that in control samples. Clinical and laboratory improvement was associated with a fall in the 8-OHdG concentration in the patients with bacterial meningitis. Our findings suggest the presence of enhanced oxidative stress in the central nervous system of children with bacterial meningitis.
