1、Steroid for Bacterial meningitis李慧玲 高雄市立小港醫院 神經科臨床問題 P (patient) : Becterial meningitis I (intervention) : Steroid C (comparison) : Placebo O (outcome) : Efficacy背景說明Steroid 在臨床上已被廣泛地應用，它具有 抗炎、止痛及減緩異常血腦障壁之微血管的 通透，以及降低顱內壓等作用。治療細菌性腦膜炎，雖然有著抗生素的介入 治療，但卻仍具高死亡率，且造成嚴重的後 遺症，不僅是一個衝擊，也是我們要去突 破的瓶頸。 背景說明 感染性疾病有
2、著強烈的地域性特色，在西方國 家細菌性腦膜炎最常見到的致病菌是鏈球菌 (Streptococcus Pneumoniae)、李斯特菌(Listeria monocytogenes)，或是奈瑟氏菌(Neisseria meningitids)；我國則是鏈球菌(Streptococcus Pneumoniae)和取而代之的克雷伯氏菌 (Klebsiella Pneumoniae)為主。 至於Steroid針對Bacterial meningitis的使用，目 前仍受爭議，至今尚無定論，但在有些病人身 上是可以加速改善症狀，但對於減少後遺症則 很難說。 期待目標 提供有用的文獻資料，期待進一步釐清

Overall, adjuvant corticosteroids were associated with lower case fatality (relativerisk (RR) 0.76, 95% condence intervals (CI) 0.59 to 0.98) and lower rates of both severe hearing loss (RR 0.36, 95% CI 0.22 to 0.60
7、) and long-term neurological sequelae (RR 0.66, 95% CI 0.44 to 0.99). In children, corticosteroids reduced severe hearing loss in bacterial meningitis caused by Haemophilus influenzae (RR 0.31, 95% CI 0.15 to 0.62), as well as in meningitis caused by other bacteria than H. influenzae (RR 0.42, 95%CI
