J Hepatol:警惕他汀类药物相关肝毒性

2012-02-17 MedSci MedSci原创

 冰岛和瑞典的一项研究显示,他汀类药物相关的特异质性肝损伤虽然罕见,但可以非常严重。如果恢复后再次用药,可再现同类型的肝损伤。大多数患者开始用他汀类药物3~4个月后发生肝损伤,阿托伐他汀最常发生胆汁淤积型肝损伤,而辛伐他汀更常见肝细胞损伤。本文发表于《肝脏病学杂志》[J Hepatol 2012,56(2):374]。   该研究对1988-2010年间瑞典药物不良反应顾问委员会收到的、怀疑由

 冰岛和瑞典的一项研究显示,他汀类药物相关的特异质性肝损伤虽然罕见,但可以非常严重。如果恢复后再次用药,可再现同类型的肝损伤。大多数患者开始用他汀类药物3~4个月后发生肝损伤,阿托伐他汀最常发生胆汁淤积型肝损伤,而辛伐他汀更常见肝细胞损伤。本文发表于《肝脏病学杂志》[J Hepatol 2012,56(2):374]。

  该研究对1988-2010年间瑞典药物不良反应顾问委员会收到的、怀疑由他汀类所致不良反应的报告进行了分析,并仅纳入转氨酶>5倍正常上限和(或)碱性磷酸酶>2倍正常上限的病例。

  共217例怀疑有药物不良反应,药物性肝损伤(DILI)最常见(57%),其中59%至少有1次可能的DILI,年龄中位数为64岁,55%为男性。所报告的他汀类药物相关性DILI发生率为1.2例/10万使用者,其中41%与阿托伐他汀相关,38%与辛伐他汀有关,15%与氟伐他汀相关。2例患者死于急性肝衰竭,1例患者接受了肝移植,25例患者发生黄疸,3例患者再次应用同一种他汀后发生了相似类型的肝损伤。

  主持人点评:医师应对服用他汀类药物的患者加强随访监测,注意新发生的恶心、乏力和腹痛等症状,并进行肝功能检测,及时发现和处理特异质性肝损伤。
