In 5 prospectively diagnosed patients with relapsing post-herpes simplex encephalitis (HSE), N-methyl-D-aspartate receptor (NMDAR) antibodies were identified. Antibody synthesis started 1 to 4 weeks after HSE, preceding the neurological relapse. Three of 5 patients improved postimmunotherapy, 1 spontaneously, and 1 has started to improve. Two additional patients with NMDAR antibodies, 9 with unknown neuronal surface antibodies, and 1 with NMDAR and unknown antibodies, were identified during retrospective assessment of 34 HSE patients; the frequency of autoantibodies increased over time (serum, p=0.004; cerebrospinal fluid, p=0.04). The 3 retrospectively identified NMDAR antibody-positive patients also had evidence of relapsing post-HSE. Overall, these findings indicate that HSE triggers NMDAR antibodies and potentially other brain autoimmunity.
在 5 例复发性单纯疱疹后脑炎(HSE)患者中,发现了 N-甲基-D-天冬氨酸受体(NMDAR)抗体。抗体合成始于 HSE 后 1 至 4 周,早于神经复发。5 例患者中有 3 例在免疫治疗后改善,1 例自发改善,1 例开始改善。在对 34 例 HSE 患者进行回顾性评估期间,还发现了另外 2 例 NMDAR 抗体阳性患者、9 例未知神经元表面抗体阳性患者和 1 例 NMDAR 和未知抗体阳性患者;自身抗体的频率随时间增加(血清,p=0.004;脑脊液,p=0.04)。这 3 例回顾性发现的 NMDAR 抗体阳性患者也有复发性 HSE 后证据。总的来说,这些发现表明 HSE 引发了 NMDAR 抗体,并可能引发其他脑自身免疫。
