The effect of a single dose of ceftazidime on circulating concentrations of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) in a rat model of sepsis was studied. IL-6 concentrations were significantly elevated (100 to 200 times the baseline) 6 h after ceftazidime administration in both septic and nonseptic (control) rats. TNF-alpha concentrations increased significantly in nonseptic (approximately 40 times the baseline) rats but not septic (approximately 2 to 3 times the baseline) rats. Ceftazidime administration was not associated with an increase in endotoxin concentrations. These findings suggest that ceftazidime modulation of proinflammatory cytokine concentrations may be independent of its antimicrobial properties.
研究了单剂量头孢他啶对脓毒症大鼠模型中白细胞介素-6(IL-6)和肿瘤坏死因子α(TNF-α)循环浓度的影响。在给予头孢他啶6小时后,脓毒症大鼠和非脓毒症(对照)大鼠的IL-6浓度均显著升高(为基线的100至200倍)。非脓毒症大鼠的TNF-α浓度显著增加(约为基线的40倍),而脓毒症大鼠的TNF-α浓度未显著增加(约为基线的2至3倍)。给予头孢他啶与内毒素浓度升高无关。这些发现表明,头孢他啶对促炎细胞因子浓度的调节可能与其抗菌特性无关。
