Insights
Treatment for bacterial meningitis in children reduces serum oxidative stress but increases oxidative stress in the cerebrospinal fluid. This study highlights the complex impact of treatment on oxidant and antioxidant balance.
Area of Science:
- Biochemistry
- Pediatric Infectious Diseases
- Neurology
Background:
- Bacterial meningitis is a serious infection affecting children.
- Oxidative stress plays a role in the pathogenesis of bacterial meningitis.
- Understanding the impact of treatment on oxidative balance is crucial for patient outcomes.
Purpose of the Study:
- To evaluate the effects of bacterial meningitis treatment on serum and cerebrospinal fluid oxidant-antioxidant status in children.
- To compare oxidative and antioxidant markers before and after treatment in pediatric patients.
Main Methods:
- Collected serum and cerebrospinal fluid from 40 children with bacterial meningitis before and after treatment.
- Collected serum from 37 healthy children as controls.
- Assessed levels of total oxidant status, lipid hydroperoxide, oxidative stress index, uric acid, albumin, ceruloplasmin, total antioxidant capacity, vitamin C, total bilirubin, and catalase.
Main Results:
- Serum oxidative stress markers (total oxidant status, lipid hydroperoxide, oxidative stress index) were significantly lower after treatment compared to before treatment.
- Cerebrospinal fluid oxidative stress markers were significantly higher after treatment than before treatment.
- Serum and cerebrospinal fluid antioxidant markers showed variable changes, with some not significantly altered by treatment.
Conclusions:
- Bacterial meningitis treatment leads to decreased oxidative stress in serum but increased oxidative stress in cerebrospinal fluid in children.
- The findings suggest a complex interplay between treatment and the oxidant-antioxidant system in the central nervous system during bacterial meningitis recovery.
Abstract:
The aim of this study was to assess the effects of meningitis treatment on the serum and cerebrospinal-fluid oxidant and antioxidant status in children with bacterial meningitis. Forty children with bacterial meningitis, at ages ranging from 4 months to 12 years (mean age, 4 years), were enrolled in the study. Within 8 hours after admission (before treatment) and 10 days after clinical and laboratory indications of recovery (after treatment), cerebrospinal fluid and venous blood were collected. Thirty-seven healthy children (mean age, 4 years) were enrolled as control subjects, and only venous blood was collected. Serum total oxidant status, lipid hydroperoxide, oxidative stress index, uric acid, albumin, and ceruloplasmin levels were lower in the patient group after treatment (P<0.05). Serum total antioxidant capacity levels, vitamin C, total bilirubin, and catalase concentrations were not significantly altered by treatment (P>0.05). However, cerebrospinal fluid total oxidant status, lipid hydroperoxide, and oxidative stress index levels were higher, and cerebrospinal fluid total antioxidant capacity levels were lower after treatment than before treatment (P<0.05). In conclusion, we demonstrated that serum oxidative stress was lower, and cerebrospinal fluid oxidative stress was higher, after rather than before treatment in children with bacterial meningitis.

For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
