Abstract

Autoimmune hemolytic anemia (AIHA) is a condition that causes an individual's immune system to destroy its own red blood cells. Immune cells are activated against the red blood cell antigens to induce hemolysis. Patients typically present with symptomatic anemia when the extent of hemolysis overcomes the bone marrow's ability to compensate. Steroids are typically the first-line treatment, along with supportive care and blood transfusion for severe anemia. This case report details a patient who had presented to the ED after a syncopal episode that was ultimately due to respiratory syncytial virus (RSV)-induced warm AIHA.

摘要

自身免疫性溶血性贫血(AIHA)是一种导致个体免疫系统破坏自身红细胞的病症。免疫细胞针对红细胞抗原被激活,从而引发溶血。当溶血程度超过骨髓的代偿能力时,患者通常会出现症状性贫血。类固醇通常是一线治疗药物,同时还包括支持性护理以及针对严重贫血的输血治疗。本病例报告详细介绍了一名患者,该患者在一次晕厥发作后被送往急诊科,最终诊断为呼吸道合胞病毒(RSV)诱发的温抗体型自身免疫性溶血性贫血。
