背景

Methylprednisolone是一种合成的糖皮质激素受体激动剂,用于迅速抑制炎症。

体外实验:低剂量methylprednisolone(2-10 mg/kg)显著抑制TNF生成,而高剂量Methylprednisolone(50 mg/kg)增加LPS诱导的IL-10水平。0.01到100 μg/ ml Methylprednisolone也增加LPS激活小鼠腹腔巨噬细胞中IL-10的生物合成[1]。在WG患者和对照中,methylprednisolone (MP)下调自发的和葡萄球菌肠毒素B(SEB)诱导的外周血单核细胞(PBMC)释放趋化因子[2]。0.25 mM methylprednisolone直接抑制皮肤培养中的棘层松解[3]。

在体实验:在SCI后立即给予30 mg/kg(i.v.)methylprednisolone降低55%的TNF-α表达(P < 0.01)和NF-kB结合活性。Methylprednisolone可以抑制由TNFα-NF-kB级联诱导的创伤后炎症活动[4]。静脉内注射MP(30 mg/kg)使ED1阳性细胞的数量在发梢残端中减少82%,在尾端残端中减少66%。在成年大鼠中,在脊髓横断后不久迅速施用MP导致ED1阳性细胞长期减少和脊髓组织损失,减少前庭绒毛膜纤维的残余,并且减少损伤后1和2周时病变附近的前庭神经纤维的短暂发芽。损伤后2、4和8周,MP显著减少两个残端的组织损失[5]。

临床试验:在国家急性脊髓损伤研究(NASCIS)中心诊断的受伤8小时内的急性脊髓损伤患者中,MP治疗48小时,在损伤后6周(P = 0.09)和6个月(P = 0.07)运动得到改善。在急性脊髓损伤患者中,以每小时每千克5.4 mg输注23小时后,30 mg/kg MP改善神经系统恢复。在MP(30 mg/kg)治疗的患者中,14天时的死亡率显著增加二次感染[7]。在严重的肾性血管炎和狼疮肾炎患者中,MP已经进入临床试验。
