typically results in acute, aggressive and angioinvasive infection, particularly in immunosuppressed individuals. Risk factors include immunosuppression in haematologic malignancy, uncontrolled hyperglycemia, iron overload states, and older chelator agents such as deferoxamine.
We describe a case of a 33-year-old female with transfusion-dependent beta thalassemia who was started on intravenous deferiprone therapy and subsequently presented with a retropharyngeal abscess. Despite intravenous broad spectrum antibiotics, she continued to deteriorate and developed aphasia. A CT scan of her head showed multiple hypodensities. Blood cultures grew species and a subsequent transesophageal echocardiogram showed a mass in the right atrium with a patent foramen ovale.
Although deferiprone, a newer iron chelator agent, has antifungal properties , this case illustrates that angioinvasive infections can occur in patients treated with deferiprone.
通常会导致急性、侵袭性和血管侵袭性感染,尤其是在免疫抑制个体中。危险因素包括血液系统恶性肿瘤中的免疫抑制、血糖控制不佳、铁过载状态以及去铁胺等较老的螯合剂。
我们描述了一名33岁依赖输血的β地中海贫血女性患者,她开始接受静脉注射去铁酮治疗,随后出现咽后脓肿。尽管使用了静脉广谱抗生素,她的病情仍持续恶化并出现失语。她的头部CT扫描显示多处低密度影。血培养培养出了菌种,随后的经食管超声心动图显示右心房有一个肿块,伴有卵圆孔未闭。
尽管新型铁螯合剂去铁酮具有抗真菌特性,但该病例表明接受去铁酮治疗的患者可能发生血管侵袭性感染。
