A 71-year-old white man developed direct antiglobulin positive haemolytic anaemia after 16 months of levodopa therapy for Parkinson's disease. Immunoglobulin G autoantibodies directed against Rh antigens were found in the patient's serum and on his erythrocytes. Reduction of levodopa dosage to one sixth with the aid of a peripheral decarboxylase inhibitor (benserazide) largely eliminated autoimmune haemolysis while maintaining adequate control of neurologic symptoms.
一名71岁白人男性在接受左旋多巴治疗帕金森病16个月后发生直接抗人球蛋白阳性溶血性贫血。在患者血清和红细胞上发现了针对Rh抗原的免疫球蛋白G自身抗体。借助外周脱羧酶抑制剂（苄丝肼）将左旋多巴剂量减至六分之一，在充分控制神经症状的同时，基本消除了自身免疫性溶血。
