This clinical trial focuses on children with malignant brain tumors, which are aggressive growths in the brain that can spread to other areas. The study aims to understand how different antibiotics behave in the body, specifically in the cerebrospinal fluid (CSF)</b), which is the fluid surrounding the brain and spinal cord. The antibiotics being studied include amoxicillin, clavulanic acid, ciprofloxacin, sulfamethoxazole, trimethoprim, cefotaxime sodium, fosfomycin, cefuroxime sodium, ceftriaxone sodium, linezolid, vancomycin, meropenem anhydrous, and gentamicin. These medications are used to treat infections and are administered either orally or through an intravenous infusion, which means they are given directly into a vein.
The purpose of the study is to measure the levels of these antibiotics in the CSF and blood plasma after they are administered to children with brain tumors that have spread or are at risk of spreading to the lining of the brain and spinal cord. This will help researchers understand how well these antibiotics can reach the CSF and potentially treat infections in this area. The study will involve regular monitoring of antibiotic levels in the body over a period of time to gather data on how the drugs are distributed and how long they stay active in the CSF.
Participants in the study will receive either the antibiotics or a placebo, and their progress will be closely monitored by medical professionals. The study is designed to provide valuable information that could improve the treatment of infections in children with brain tumors, helping to ensure that the antibiotics used are effective in reaching the areas where they are needed most. This research is important for developing better treatment strategies for managing infections in children with these serious conditions.
