Levamisole-induced vasculitis (LIV) is becoming an increasingly common entity secondary to both rising cocaine use in the UK and high levels of adulteration of cocaine with various contaminants. We report the first documented case of LIV secondary to adulterated cocaine in Ireland, which presented as a 6-year history of recurrent vasculitis of unknown aetiology. Classically, LIV is diagnosed by a combination of positive ANCA serology and agranulocytosis however, given the frequency of cocaine use, we urge acute physicians to consider the diagnosis in cases of typical retiform (angulated) purpura in association with a history of cocaine use.
左旋咪唑诱导的血管炎(LIV)在英国因可卡因使用量上升以及可卡因被各种污染物高度掺假而成为越来越常见的病症。我们报告了爱尔兰首例有记录的因掺假可卡因导致的LIV病例,该病例表现为6年不明病因的复发性血管炎病史。经典地,LIV通过抗中性粒细胞胞浆抗体(ANCA)血清学阳性和粒细胞缺乏症来诊断,然而,鉴于可卡因使用的频率,我们敦促急症医生在出现典型的网状(角形)紫癜且有可卡因使用史的病例中考虑该诊断。
