深圳市首例H5N1型人禽流感临床报告

目的探索H5N1型人禽流感病例的临床特点及诊治经验。方法一例H5N1型人禽流感患者,采用荧光定量RT-PCR评价抗病毒治疗效果,流式细胞术监测细胞免疫,即时动态的放射学检查、血气分析、生化检查监测病情变化,即时的细菌学检查监测细菌感染情况和抗生素治疗效果。采用抗病毒、禽流感恢复期血浆、机械辅助通气、糖皮质激素、免疫调节、抗生素、对症支持等综合治疗。结果患者以高热、咳嗽、呼吸困难为主要症状,临床诊断为重症病毒性肺炎,合并急性呼吸窘迫综合征(ARDS)和多脏器功能衰竭,并继发严重肺部细菌感染。联合奥司他韦和禽流感患者恢复期血浆治疗,患者体内的病毒在短期内得到有效控制和清除;机械通气、激素及其他对症支持治疗有效控制ARDS和多脏器功能衰竭;多黏菌素治疗有效控制广泛耐药的铜绿假单胞菌感染;免疫调节治疗促进患者免疫功能的恢复。结论H5N1型人禽流感病情重、进展快,严重的ARDS及多器官功能障碍综合征是主要临床特征。早期清除病毒、及时正确的对症辅助支持治疗、选择有效抗生素控制继发细菌感染是治疗成功的关键。激素和免疫调节剂的使用值得进一步探索。恢复期血浆治疗是重症禽流感治疗的有益尝试。

Successful treatment of the first case of human H5N1 avian influenza in Shenzhen

was recovered by the comprehensive treatment with glucocorticoids,mechanical ventilation and other measurements mentioned above.Conclusions Severe ARDS and MODS is the main characteristics of human H5N1 avian influenza,which cause high morbidity.The comprehensive treatments including effective antiviral treatment at early phase,successful treatment of ARDS and MODS,prevention and control secondary microbial infection are critical for the recovery of the patient.The antiviral effect of convalescent plasma therapy is encouraging.
