A 66 year old patient with multiple myeloma and monoclonal cryoglobulinaemia who developed a severe haemolytic anaemia following a cytomegalovirus infection is reported. The presence of a high titre of anti-'i' cold antibody of IgM subclass is demonstrated. Anti-'i' antibody disappeared when complement-fixation antibody titres against cytomegalovirus decreased. Various pathogenetic mechanisms involved in the development of haemolytic anaemia associated with cytomegalovirus infection are discussed. To our knowledge, this is the first case described in the English language publications associating severe haemolytic anaemia with an anti-'i' antibody after a cytomegalovirus infection in an immunocompromised patient.
报告了一名66岁患有多发性骨髓瘤和单克隆冷球蛋白血症的患者,其在巨细胞病毒感染后发生了严重的溶血性贫血。证实存在高滴度的IgM亚类抗“i”冷抗体。当针对巨细胞病毒的补体结合抗体滴度降低时,抗“i”抗体消失。讨论了与巨细胞病毒感染相关的溶血性贫血发生过程中涉及的各种发病机制。据我们所知,这是英文出版物中描述的首例免疫功能低下患者在巨细胞病毒感染后出现严重溶血性贫血并伴有抗“i”抗体的病例。
