[Clinical and prognostic study of anti-N-methyl-D-aspartate receptor encephalitis children with paroxysmal sympathetic hyperactivity syndrome].

The data of clinical characteristics, medical cost and prognosis of 22 anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis children from the Department of Neurology, Capital Institute of Pediatrics between May 2018 and January 2021 were analyzed, and 6 of them occurred paroxysmal sympathetic hyperactivity syndrome (PSH). It was found that the anti-NMDAR encephalitis children with PSH had severer consciousness disorder [median Glasgow Coma Scale (GCS) score at admission: 7.5], longer duration of consciousness disorder (median time: 53 days), higher hospitalization cost (median cost: 230 000 RMB), severer neurological injury at onset [median modified Rankin Scale (mRS) score at admission: 4], and longer recovery time of neurological function (median time of mRS score recovered to 0-2: 7 months), compared with those without PSH (all P<0.05). Therefore, more attention should be paid to sympathetic excited symptoms of anti NMDAR encephalitis, and thus identify and intervene early on PSH to reduce the neurological damage and economic burden.分析了2018年5月至2021年1月首都儿科研究所附属儿童医院神经内科收治的22例抗N-甲基-D-天冬氨酸受体（NMDAR）脑炎中，6例伴发交感神经过度兴奋综合征（PSH）患儿的临床特征、花费及预后，发现伴PSH的抗NMDAR脑炎意识障碍重（入院时GCS中位评分7.5分）、意识障碍持续时间长（中位天数53 d）、住院花费高（中位花费23.0万元）、起病时神经功能损伤重（入院时mRS中位分数4分）、神经功能恢复时间长（mRS恢复至0~2分，中位时间7个月），与不伴PSH的抗NMDAR脑炎患儿比较差异均有统计学意义（P<0.05）。故应重视抗NMDAR脑炎的交感神经兴奋症状，早期识别并干预PSH，以期减少疾病对患者神经功能的损伤及经济负担。.
