: The ongoing SARS-CoV-2 pandemic is a serious threat for the health of immunocompromised patients. Among neutralizing antibody-based therapeutics, convalescent plasma containing polyclonal anti-SARS-CoV-2 immunoglobulins has promising results in both congenital and iatrogenic immunodeficiencies in oncohematological and transplant patients.
: This article discusses case reports, case series and controlled studies detailing the efficacy of convalescent plasma in immunocompromised patients.
: Convalescent plasma, when administered at high neutralizing antibody titers, is a safe and effective treatment for frail immunocompromised patients. Genetic monitoring of refractory patients is recommended to intercept intra-host emergence of SARS-CoV-2 variants.
持续的 SARS-CoV-2 大流行对免疫功能低下患者的健康构成严重威胁。在基于中和抗体的治疗方法中,含有 SARS-CoV-2 多克隆中和抗体的恢复期血浆在血液肿瘤和移植患者的先天性和医源性免疫缺陷中具有良好的效果。
本文讨论了详细介绍恢复期血浆在免疫功能低下患者中的疗效的病例报告、病例系列和对照研究。
当恢复期血浆中的中和抗体滴度较高时,对虚弱的免疫功能低下患者是一种安全有效的治疗方法。建议对难治性患者进行基因监测,以拦截 SARS-CoV-2 变异株在体内的出现。
