Abstract：
Cold agglutinin syndrome (CAS) is a rare subset of autoimmune hemolytic anemia (AIHA) and can be classified as either primary or secondary. Secondary cold agglutinin disease has been associated with both viral and bacterial pathogens with the most common bacterial pathogen being Mycoplasma pneumoniae. Legionella pneumonia is a well-known causative agent for community-acquired pneumonia that can lead to a severe disease requiring hospitalization that is rarely associated with AIHA. We highlight the importance of recognizing Legionella pneumonia as a causative pathogen for CAS.
摘要：
冷凝集素综合征（CAS）是自身免疫性溶血性贫血（AIHA）的罕见子集，可分为原发性或继发性。继发性冷凝集素病与病毒和细菌病原体有关，最常见的细菌病原体是肺炎支原体。军团菌肺炎是众所周知的社区获得性肺炎的病原体，可导致需要住院治疗的严重疾病，很少与AIHA相关。我们强调承认军团菌肺炎是CAS的致病病原体的重要性。
