摘要目的:探索直接肾素抑制剂阿利吉仑用于重型新型冠状病毒肺炎（COVID-19）合并高血压患者治疗的可行性。方法:回顾性病例分析3例重型及1例危重型COVID-19合并高血压患者应用阿利吉仑降血压治疗的有效性和安全性。结果:4例患者，男2例，女2例，平均年龄78岁（66~87岁），均以呼吸道症状起病，3例经新型冠状病毒（2019-nCoV）核酸或抗体检测确诊（重型），1例为临床诊断合并心功能不全（危重型）。既往高血压病诊断明确，2例服用钙离子拮抗剂（CCB），1例服用血管紧张素转换酶抑制剂（ACEI），1例服用血管紧张素Ⅱ受体拮抗剂（ARB）治疗。入院后停用ACEI或ARB，1例患者因心力衰竭采用阿利吉仑联合利尿剂治疗；3例患者用阿利吉仑联合CCB治疗，其中2例患者治疗1~2周后因血压偏低而停用CCB。在抗病毒、改善氧合的综合治疗基础上服用阿利吉仑降压治疗3~4周，4例患者血压控制满意且无不适主诉，病情好转，均已达到出院标准并已出院。结论:初步临床结果显示阿利吉仑对重型COVID-19合并高血压患者的降压治疗是有效和安全的，但应增加病例数进一步做相关的临床治疗研究。

abstractsObjective:To explore the feasibility of direct renin inhibitor aliskiren for the treatment of severe or critical coronavirus disease 2019 (COVID-19) patients with hypertension.Methods:The antihypertensive effects and safety of aliskiren was retrospectively analyzed in three severe and one critical COVID-19 patients with hypertension.Results:Four patients, two males and two females, with an average age of 78 years (66-87 years), were referred to hospital mainly because of respiratory symptoms. Three were diagnosed by positive novel coronavirus 2019 (2019-nCoV) nucleic acid or antibody, and the critical patient with cardiac insufficiency was clinically determined. Two patients were treated with calcium channel antagonist (CCB), one with angiotensin converting enzyme inhibitor (ACEI), and one with angiotensin Ⅱ receptor antagonist (ARB). After admission, ACEI and ARB were discontinued, one patient with heart failure was treated by aliskiren combined with diuretic.Three patients were treated with aliskiren combined with CCB among whom two withdrew CCB due to low blood pressure after 1 to 2 weeks. Based on comprehensive treatment including antiviral and oxygenation treatment, blood pressure was satisfactorily controlled by aliskiren after three to four weeks without serious adverse events. All patients were finally discharged.Conclusion:Our preliminary clinical data shows that antihypertensive effect of aliskiren is satisfactory and safe for severe COVID-19 patients complicated with hypertension.
