Juvenile hemochromatosis (JH) is a rare autosomal recessive disorder of iron metabolism, genetically heterogeneous. In JH, symptomatic organ involvement occurs as early as the second decade of life. Heart failure and/or arrhythmias are the most frequent causes of death. Phlebotomy is the safest, most effective, and most economic therapeutic approach in hemochromatosis patients but is not indicated during the treatment of severe congestive heart failure with unstable hemodynamic status. The treatment of iron overload in these prohibitive clinical situations has to be carried out using iron chelators. We report a case of heart failure in the setting of unrecognized juvenile hemochromatosis successfully treated by the simultaneous administration of deferoxamine and deferiprone. To our knowledge, this is the first patient affected by JH treated with combined chelation regimen.
青少年血色病(JH)是一种罕见的常染色体隐性铁代谢紊乱疾病,具有遗传异质性。在青少年血色病中,有症状的器官受累早在生命的第二个十年就会出现。心力衰竭和/或心律失常是最常见的死亡原因。放血疗法是血色病患者最安全、最有效且最经济的治疗方法,但在严重充血性心力衰竭且血流动力学状态不稳定的治疗期间并不适用。在这些禁忌的临床情况下,必须使用铁螯合剂来治疗铁过载。我们报告了一例未被识别的青少年血色病合并心力衰竭的病例,通过同时给予去铁胺和地拉罗司成功治疗。据我们所知,这是首例接受联合螯合疗法治疗的青少年血色病患者。
