Elderly patients are having high mortality rates from COVID-19/SARS-CoV-2 infection compared to younger patients. The SARS-CoV-2 virus uses the ACE2 receptor as the entry point to the host cells. ARBs/ACEIs which are widely used in elderly patients, have been found to be associated with overexpression of ACE2.To decrease the severity of COVID-19 infection, ARB/ACEI should be switched to another class drug not known to cause a rise in ACE2 until the COVID-19 infection subsides. Specific human immunoglobulin can be tried for COVID-19 patients with critical conditions under supervision.
与年轻患者相比,老年患者因新型冠状病毒肺炎/严重急性呼吸综合征冠状病毒2(COVID-19/SARS-CoV-2)感染而死亡率较高。SARS-CoV-2病毒利用血管紧张素转换酶2(ACE2)受体作为进入宿主细胞的切入点。已发现广泛用于老年患者的血管紧张素Ⅱ受体阻滞剂(ARBs)/血管紧张素转换酶抑制剂(ACEIs)与ACE2的过度表达有关。为降低COVID-19感染的严重程度,在COVID-19感染消退之前,应将ARB/ACEI换用另一类已知不会导致ACE2升高的药物。对于病情危急的COVID-19患者,可在监护下尝试使用特异性人免疫球蛋白。
