摘要:

目的 应用微量血清杀菌活性(SBA) 测定对肾功能不全患者在抗菌药物临床治疗过程进行监测,对用药剂量和间隔时间进行合理调整,制定个体化给药方案,以提高药效和减少毒副作用。方法 按肾功能减退时抗菌药物用药调整方案对使用头孢类抗菌药物治疗的48例肾功能不全[肾小球滤过率(GFR)<50 mL/min]住院患者(中度肾功能不全患者36例,重度肾功能不全患者12例)进行治疗,应用自行设计的SBA方法测定患者峰时和谷时的SBA浓度。结果 36例中度肾功能不全患者SBA测定结果峰值为1∶32~1∶128(中位数为1∶64),谷值为1∶8~1∶64(中位数为1∶32);12例重度肾功能不全患者SBA测定结果峰值为1∶64~1∶512(中位数为1∶128),谷值为1∶16~1∶128(中位数为1∶64)。两组患者SBA均高于合理建议值(P<0.01)。结论 肾功能不全患者在应用经肾脏代谢的抗菌药物时,存在用药过量而导致毒副作用的增加,加重肾功能的损害。肾功能不全的患者使用经肾脏代谢的抗菌药物治疗时,应同时进行SBA监测。

Abstract:

Objective To monitor serum bactericidal activity(SBA) determination in renal insufficiency patients during antibiotics treatment, to adjust the antibiotics dosage and dosing interval, to formulate individualized dosing regimen, and to improve the treatment and decrease the side effects. Methods A total of 48 renal insufficiency [glomerular filtration rate(GFR)<50 mL/min] patients undergoing cephalosporin treatment were enrolled, including 36 cases with middle renal insufficiency and 12 cases with severe renal insufficiency, their antibiotics dosage and dosing interval were adjusted according to the guideline of antibiotics treatment for renal insufficiency patients, and the peak and valley SBA values were measured by the method we designed. Results In 36 patients with middle renal insufficiency, the peak SBA value was 1∶32-1∶128(median 1∶64), and the valley SBA value was 1∶8-1∶64(median 1∶32). In 12 patients with severe renal insufficiency, the peak SBA value was 1∶64-1∶512(median 1∶128), and the valley SBA value was 1∶16-1∶128(median 1∶64). The SBA values in the 2 groups were all higher than reasonable suggestion value(P<0.01). Conclusions In patients with renal insufficiency undergoing antibiotics treatment mainly metabolized by kidney, there will increase the side effects and renal insufficiency. It should monitor SBA value, when using antibiotics mainly metabolized by kidney in patients with renal insufficiency.
