药物诱发的免疫性溶血性贫血

摘要

药物诱发的免疫性溶血性贫血( DIIHA)少见.临床表现为中重度溶血性贫血常见机制是产生药物依赖性抗体,常见药物为抗生素(如头孢替坦、头孢曲松钠和哌拉西林).少见机制是产生非药物依赖的自身抗体,致特发性温抗体型自身免疫性溶血性贫血,最常见药物是氟达拉滨.治疗首要是停药,并积极处理合并症.%Drug-induced immune hemolytic anemia (DHHA) is seldom seen,whose clinical manifestation is mild-to-severe hemolytic anemia. The common mechanism is the presence of drug-dependent antibodies,and the common drugs are antibiotics, such as cefotetan,ceftriaxone and piperacillin. On other hand,the uncommon mechanism is the presence of non-drug-dependent antibodies that can lead to idiopathic autoimmune hemolytic anemia. In such case,the most common drug is flu-darabine. Importantly,drug use should be stopped and the complications be actively treated.
