持续皮下胰岛素输注在人胰岛素过敏患者脱敏治疗中的应用

目的评价持续皮下胰岛素输注法在人胰岛素过敏患者脱敏治疗中的应用价值。方法对2例人胰岛素过敏患者采用赖脯胰岛素持续皮下泵入治疗，以0．01U／h稀释赖脯胰岛素溶液为起始基础率，逐步增加输注速率和浓度直至临床所需剂量，在此基础上调整治疗方案为3餐前皮下注射赖脯胰岛素联合口服药物治疗。结果2例患者在持续皮下赖脯胰岛素输注治疗的起始及加量过程中均未出现皮肤瘙痒症状，注射局部亦无风团出现：改用餐前皮下赖脯胰岛素注射联合口服药治疗后亦无上述症状出现。结论持续皮下输注胰岛素或速效胰岛素类似物可用于人胰岛素过敏患者的脱敏治疗。

Application of continuous subcutaneous insulin infusion in desensitization for allergy to recombinant human insulin

Objective To evaluate the values of continuous subcutaneous insulin/rapid insulin analoguc infusion in desensitization for allergy to recombinant human insulin. Methods Two patients allergic to recombinant human insulin received desensitization therapy by continuous subcutaneous insulin lispro infusion. The diluted insulin lispro solution was pumped with initial basal rate of O. O1 U/h, and the basal rate and insulin lispro concentration increased gradually until the insulin dosage for clinical treatment was reached. After that, continuous subcutaneous insulin lispro infusion was replaced by regimen of insulin lispro subcutaneous injection plus oral hypoglycemic agents. Results Local wheals were not observed in both two patients during continuous subcutaneous insulin lispro infusion or during bolus subcutaneous injection of insulin lispro after desensitization. Conclusion The desensitization therapy by continuous subcutaneous insulin/rapid insulin analogue infusion can be applied for allergy to recombinant human insulin.
