To report two female patients with paraneoplastic cerebellar degeneration (PCD) related to breast cancer that presented with rapid eye movement-sleep behavior disorder (RBD) and improved sleep symptoms with immunotherapy.
The two patients were evaluated through clinical scale and polysomnography before and after therapy with intravenous immunoglobulin.
RBD was successfully treated with immunotherapy in both patients. Score on the RBD screening questionnaire dropped from 10 to 1 or 0, allied with the normalization of polysomnographic findings.
A marked improvement in RBD after immunotherapy in PCD raises the hypothesis that secondary RBD may be an immune-mediated sleep disorder.
报告两例与乳腺癌相关的副肿瘤性小脑变性(PCD)女性患者,她们表现出快速眼动睡眠行为障碍(RBD),且免疫治疗后睡眠症状改善。
在静脉注射免疫球蛋白治疗前后,通过临床量表和多导睡眠图对这两名患者进行评估。
两名患者的RBD均通过免疫治疗成功治愈。RBD筛查问卷评分从10降至1或0,同时多导睡眠图检查结果恢复正常。
PCD患者免疫治疗后RBD明显改善,这提示继发性RBD可能是一种免疫介导的睡眠障碍。
