Antibiotic-induced bacteriolysis exacerbates inflammation and brain damage in bacterial meningitis. Here the quality and temporal kinetics of cerebrospinal fluid (CSF) inflammation were assessed in an infant rat pneumococcal meningitis model for the nonbacteriolytic antibiotic daptomycin versus ceftriaxone. Daptomycin led to lower CSF concentrations of interleukin 1beta (IL-1beta), IL-10, IL-18, monocyte chemoattractant protein 1 (MCP-1), and macrophage inflammatory protein 1 alpha (MIP-1alpha) (P < 0.05). In experimental pneumococcal meningitis, daptomycin treatment resulted in more rapid bacterial killing, lower CSF inflammation, and less brain damage than ceftriaxone treatment.
抗生素诱导的细菌溶解会加剧细菌性脑膜炎的炎症和脑损伤。在这里,评估了非溶菌性抗生素达托霉素与头孢曲松在婴儿大鼠肺炎球菌性脑膜炎模型中的脑脊液(CSF)炎症的质量和时间动力学。达托霉素导致 CSF 中白细胞介素 1β(IL-1β)、IL-10、IL-18、单核细胞趋化蛋白 1(MCP-1)和巨噬细胞炎症蛋白 1α(MIP-1α)浓度降低(P < 0.05)。在实验性肺炎球菌性脑膜炎中,与头孢曲松治疗相比,达托霉素治疗导致更快的细菌清除、更低的 CSF 炎症和更少的脑损伤。
