We report the case of a 75-year-old Chinese lady that presented delusional parasitosis with visual hallucinations four months after starting peritoneal dialysis. This psychosis is characterized by the persistent and unshakable belief of being infested with small living organisms, although there is no medical evidence for this. The patient had no previous history of psychiatric disorders, presented diminished visual acuity due to cataracts and macular degeneration, did not show cognitive deterioration, and was medicated with erythropoietin. During the course of the psychosis she presented an episode of visual hallucinations possibly related to Charles Bonnet syndrome. After two months of treatment with aripiprazole the psychotic symptoms remitted considerably. Aripiprazole is a neuroleptic to consider in the treatment of delusional parasitosis.
我们报告了一例75岁中国女性患者的病例，该患者在开始腹膜透析四个月后出现伴有视幻觉的妄想性寄生虫病。这种精神病的特征是持续且坚定不移地相信自己被微小的生物感染，尽管并无医学证据支持这一点。该患者既往无精神疾病史，因白内障和黄斑变性导致视力下降，未出现认知衰退，且正在接受促红细胞生成素治疗。在精神病病程中，她出现了一次可能与查尔斯·邦尼特综合征相关的视幻觉发作。使用阿立哌唑治疗两个月后，精神病症状显著缓解。阿立哌唑是治疗妄想性寄生虫病时可考虑使用的一种抗精神病药物。
