Hydralazine is rarely associated with antineutrophilic cytoplasmic antibody (ANCA) vasculitis. In the appropriate clinical scenario, such as in a patient with pulmonary, renal, or cutaneous manifestations, finding antibodies against nuclear and cytoplasmic neutrophil antigens may suggest drug-induced vasculitis after exposure to hydralazine. We present the case of an elderly man diagnosed with focal alveolar hemorrhage with elevated concentrations of anti-myeloperoxidase antibody, anti-proteinase-3 antibody, and antinuclear antibodies in the setting of prolonged hydralazine therapy. We observed a rapid clinical improvement with hydralazine discontinuation and systemic corticosteroids. We did not observe further disease activity while on mycophenolate mofetil six months later.
肼屈嗪很少与抗中性粒细胞胞浆抗体(ANCA)血管炎相关。在合适的临床情况下,比如在有肺部、肾脏或皮肤表现的患者中,发现抗核及抗中性粒细胞胞浆抗原的抗体可能提示在接触肼屈嗪后发生了药物性血管炎。我们报告一例老年男性病例,该患者在长期接受肼屈嗪治疗的情况下,被诊断为局灶性肺泡出血,同时抗髓过氧化物酶抗体、抗蛋白酶-3抗体和抗核抗体浓度升高。停用肼屈嗪并给予全身性糖皮质激素治疗后,我们观察到患者临床症状迅速改善。六个月后,患者在接受霉酚酸酯治疗期间未观察到疾病进一步活动。
